Platinum-based adjuvant chemotherapy on moderate - and high-risk stage I and II epithelian ovarian cancer patients. Long-term single institution exper



Background Although the optimal management of women with FIGO stages I and II epithelial ovarian cancer (EOC) is still controversial, platinum-based adjuvant chemotherapy (CT) is the mainstay of treatment. Suboptimal survival results have led to major efforts to identify prognostic factors, improve surgical staging and develop adjuvant therapies to improve patients' outcomes.

Patients and methods We evaluate in a retrospective study clinical efficacy and the toxicity profile of a platinum-based adjuvant CT in FIGO stages I and II EOC treated at our institution from March 1984 to December 2006. Grade I FIGO stages IA-IB were excluded from the analysis. In the first period (1984-1997), patients received a platinum-based regimen without taxanes. In the second period from 1997 onwards, patients were treated with carboplatin and paclitaxel. Four to six cycles of adjuvant CT were administered. Potential predictive factors of efficacy and the role of paclitaxel addition were also analysed.

Results One hundred and fifty-eight patients (60 treated with paclitaxel) met inclusion criteria and were evaluable. Median age at diagnosis was 53.7 years (range 19-81) and most patients had an Eastern Cooperative Oncology Group performance status score (ECOG) of 0-1 (91.8%); 82.9% patients had pathological stage I and 17.1% pathological stage II. With a median follow up of 8.34 years (range 4.4-11.6), 103 patients (74.1%) were free of disease and 110 of them were alive (79.1%). Median relapse-free survival (RFS) and median overall survival (OS) had not been reached at the time of the analysis. No survival difference was found between paclitaxel and carboplatin combination or non-paclitaxel-containing regimens. Statistically significant prognostic factors for better RFS in the multivariate analysis were: ECOG 0 (p=0.023; HR 0.32; 95% CI 0.17-0.57); FIGO I stage (p<0.001; HR 0.30; 95% CI 0.15-0.58); I-II histological grade (p=0.005; HR 0.38; 95% CI 0.19-0.75); mucinous histology (p=0.013; HR 0.28; 95% CI 0.13-0.53); non-surgical adherences (p<0.002, HR 0.32; 95% CI 0.15-0.54); paracolic gutters inspection (p=0.033; HR 0.50; 95% CI 0.26-0.95) and liver surface biopsies (p=0.048; HR 0.64; 95% CI 0.41-0.98).Toxicity was generally mild and non-haematologic events were the most commonly found (62.9% of the total). The most frequent haematologic toxicities were neutropenia (41.7% in all grades, 9.5% grade 3-4) and anaemia (29.1% in all grades, 3.2% grade 3-4).

Conclusions The long-term outcome of this series is comparable to the published evidence and reflects the limited activity of platinum-based CT in the adjuvant setting. The potential survival advantage of the addition of paclitaxel to carboplatin cannot be definitively answered due to the small number of patients, the limited follow-up and the retrospective nature of the study. More effective and specific treatments are clearly required, in particular for those patients with stage II and undifferentiated tumours. Quality of surgery entails prognostic value.

Lynch Syndrome and MYH-Associated Polyposis: Review and Testing Strategy. Goodenberger M, Lindor NM.



Abstract
Individuals with Lynch syndrome have an increased risk for colorectal cancer, endometrial cancer, and other associated cancers such as gastric cancer, ovarian cancer, urothelial cancers, hepatobiliary tract cancer, brain cancer, cancer of the small intestine, pancreatic cancer, and particular skin cancers.
Lynch syndrome caused by defects in DNA mismatch repair genes, and diagnostic testing for Lynch syndrome begins with microsatellite instability and immunohistochemical analysis on the tumor specimen followed by germline genetic testing and possibly further studies on the tumor. MYH-associated polyposis syndrome is a recently characterized, autosomal recessive, polyposis syndrome caused by biallelic mutations in the MYH gene. Individuals carrying 2 copies of the mutation have a significantly increased risk of polyposis, colorectal cancer, upper gastrointestinal polyps and additional features commonly seen in familial adenomatous polyposis syndrome. Genetic testing for MYH mutation is complicated by the phenotypic overlap of MYH-associated polyposis with other colorectal cancer syndromes. This study serves to clarify the best testing approach.

Surgical management of bowel obstruction in gynaecological malignancies.



Abstract

PURPOSE OF REVIEW: Bowel obstruction in gynaecological malignancies continues to present clinical challenges and a multidisciplinary approach to discuss management is crucial. Surgery, usually with palliative intent, is associated with significant morbidity and mortality. There is an absence of level 1 evidence and national guidelines, and only limited quality-of-life data.
RECENT FINDINGS: Acute bowel obstruction in gynaecological cancer patients is rare and surgery is associated with a higher morbidity and mortality rate. Less commonly, emergency bowel obstruction cases will have had radiotherapy or recent chemotherapy, which also increases surgical morbidity and mortality. However, most often, bowel obstruction in irradiated gynaecological cancer patients is not due to cancer. Ovarian cancer is the most common malignancy. Caution is needed in those EOC patients with ascites, short treatment-free interval, acute abdomen and chemoresistance. Comorbidities are frequent. The decision for surgery should be made on an individual basis. Palliative care input is important early in patient management as for most patients the surgical goal is palliation and not cure. There is still a paucity of published data on quality-of-life assessments.
SUMMARY: There is a need to identify those patients who may benefit from palliative surgical intervention and those who will not. Ideally, agreed national guidelines should be produced and regularly reviewed.

Undetectable antimüllerian hormone levels and recovery of chemotherapy-induced ovarian failure in women with breast cancer on an oral aromatase inhibitors



Abstract
OBJECTIVE: Knowledge of the menopause status of a woman with breast cancer is important for good clinical practice. Long-lasting amenorrhea is frequent in this population, often for reasons other than definitive menopause. Antiestrogens like tamoxifen or oral aromatase inhibitors (AIs) may reactivate the ovary causing vaginal bleeding, menstruation, pregnancy, and unopposed endometrial stimulation. In contrast to tamoxifen, AIs are not active against breast cancer in the presence of functional ovaries. Antimüllerian hormone (AMH) is a potential marker of residual ovarian function that can predict not only the onset of menopause but also chemotherapy-induced amenorrhea (CIA) and fertility. We assess the value of AMH in women who recovered from CIA on an AI.

Retrospective study of the impact of pharmacogenetic variants on paclitaxel toxicity and survival in patients with ovarian cancer.



PURPOSE: Paclitaxel has a broad spectrum of anti-tumor activity and is useful in the treatment of ovarian, breast, and lung cancer. Paclitaxel is metabolized in the liver by CYP2C8 and CYP3A4 and transported by P-glycoprotein. The dose-limiting toxicities are neuropathy and neutropenia, but the interindividual variability in toxicity and also survival is large. The main purpose of this study was to investigate the impact of genetic variants in CYP2C8 and ABCB1 on toxicity and survival.
METHODS: The 182 patients previously treated for ovarian cancer with carboplatin and paclitaxel in either the AGO-OVAR-9 or the NSGO-OC9804 trial in Denmark or Sweden were eligible for this study. Genotyping was carried out on formalin-fixed tissue. The patients' toxicity profiles and survival data were derived from retrospective data. CYP2C8*3, ABCB1 C1236T, G2677T/A, and C3435T were chosen a priori for primary analysis; a host of other variants were entered into an exploratory analysis.
RESULTS: Clinical data and tissue were available from a total of 119 patients. Twenty-two single nucleotide polymorphisms (SNPs) in 10 genes were determined. Toxicity registration was available from 710 treatment cycles. In the primary analysis, no statistically significant correlation was found between CYP2C8*3, ABCB1 C1236T, G2677T/A, and C3435T and neutropenia, sensoric neuropathy, and overall survival.
CONCLUSION: CYP2C8*3 and the ABCB1 SNPs C1236T, G2677T/A, and C3435T were not statistically significantly correlated to overall survival, sensoric neuropathy, and neutropenia in 119 patients treated for ovarian cancer with paclitaxel/carboplatin.

Sugars in diet and risk of cancer in the NIH-AARP diet and health study



Abstract
Prospective epidemiologic data on the effects of different types of dietary sugars on cancer incidence have been limited. In this report, we investigated the association of total sugars, sucrose, fructose, added sugars, added sucrose and added fructose in the diet with risk of 24 malignancies.
Participants (n = 435,674) aged 50-71 years from the NIH-AARP Diet and Health Study were followed for 7.2 years. The intake of individual sugars was assessed using a 124-item food frequency questionnaire (FFQ)......... We identified 29,099 cancer cases in men and 13,355 cases in women. In gender-combined analyses, added sugars were positively associated with risk of esophageal adenocarcinoma ; added fructose was associated with risk of small intestine cancer ; and all investigated sugars were associated with increased risk of pleural cancer. In women, all investigated sugars were inversely associated with ovarian cancer. We found no association between dietary sugars and risk of colorectal or any other major cancer.
Measurement error in FFQ-reported dietary sugars may have limited our ability to obtain more conclusive findings. Statistically significant associations observed for the rare cancers are of interest and warrant further investigation.

Long-term clinical and immunological effects of p53-SLP® vaccine in ovarian cancer patients



Abstract

Vaccine-induced p53-specific immune responses were previously reported to be associated with improved response to secondary chemotherapy in small cell lung cancer patients. We investigated longterm clinical and immunological effects of the p53-SLP® vaccine in recurrent ovarian cancer patients. Twenty patients were immunized with the p53-SLP® vaccine between July 2006 and August 2007.
Follow-up information on patients was obtained. Clinical responses to secondary chemotherapy after p53-SLP® immunizations was determined by computerized tomography and/or tumour marker levels (CA125). Disease-specific survival was compared with a matched historical control group. Immune responses were analysed by flow cytometry, proliferation assay, IFN-γ ELISPOT and/or cytokine bead array. Lymphocytes cultered from skin biopsy were analysed by flow cytometry and proliferation assay.
Of twenty patients treated with the p53-SLP® vaccine, seventeen were subsequently treated with chemotherapy. Eight of these volunteered another blood sample. No differences in clinical response rates to secondary chemotherapy or disease-specific survival were observed between immunized patients and historical controls (p=0.925, resp. p=0.601). P53-specific proliferative responses were observed in 5/8 patients and IFN-γ production in 2/7 patients. Lymphocytes cultured from a prior injection site showing inflammation during chemotherapy did not recognise p53-SLP®. Thus treatment with the p53- SLP® vaccine does not affect responses to secondary chemotherapy or survival, although p53-specific T-cells do survive chemotherapy.

Phase II Clinical Study of the Combination Chemotherapy Regimen of Irinotecan Plus Oral Etoposide for the Treatment of Recurrent Ovarian Cancer




OBJECTIVE: To evaluate the efficacy and safety of the combination chemotherapy regimen of irinotecan plus oral etoposide for the treatment of patients with recurrent ovarian cancer after previous treatment with platinum and taxane agents.
PATIENTS AND METHODS: A total of 42 patients with recurrent ovarian cancer who had an evaluable lesion and provided informed consent for participation in the present study were analyzed. Irinotecan was administered intravenously at a dose of 60 mg/m on days 1 and 15. Etoposide was administered orally at a daily dose of 50 mg/body weight from days 1 to 21. A 28-day period comprised one cycle. The tumor response, adverse events, progression-free survival, and overall survival were examined. Tumor response was evaluated based on the Response Evaluation Criteria in Solid Tumors and the serum CA125 levels (Gynecologic Cancer Intergroup criteria). Adverse events were assessed according to the NCI-CTCAE (version 3.0).
RESULTS: Partial response was observed in 21 patients, stable disease in 14 patients, and progressive disease in 7 patients. The response rate was 50.0%, and the clinical benefit (partial response + stable disease) rate was 83.3%. Hematological toxicities of at least grade 3 severity included leukopenia in 21 patients (50.0%), neutropenia in 22 patients (52.4%), thrombocytopenia in 1 patient (2.4%), anemia in 9 patients (21.4%), and febrile neutropenia in 3 patients (7.1%). Nonhematological toxicities of at least grade 3 severity included queasy feeling in 5 patients (11.9%), vomiting in 3 patients (7.1%), and diarrhea in 2 patients (4.8%). Acute myeloid leukemia occurred in one patient (2.4%).
CONCLUSIONS: It is suggested that combination chemotherapy with irinotecan plus oral etoposide offers significant clinical benefit to patients with recurrent ovarian cancer previously treated with platinum and taxane agents.

Diagnostic performance of urgent referrals for suspected gynaecological malignancies.



PURPOSE: The objective of this study was to investigate the outcome of the urgent referrals with suspected gynaecological malignancy.
CONCLUSION: The overall predictive value of two-week wait referrals for suspected gynaecological malignancies is low. Refinement of the current referral guidelines is required with particular emphasis in the premenopausal women where the diagnostic performance of the urgent referrals is significantly poorer.

Studying Therapy Response and Resistance in Mouse Models for BRCA1-Deficient Breast Cancer




Gynecological Cancers. [Methods Mol Biol. 2011]



Abstract
The clinical problems raised in patients presenting with all forms of gynecological malignancy are currently addressed using conventional cross-sectional imaging, usually MRI. In general, F-18 FDG PET-CT has not been shown to have a clinical role in any of these cancers at presentation, although studies are under way to use this form of metabolic imaging to predict prognosis and the response to treatment. Although F-18 FDG PET-CT is superior to conventional imaging techniques, it is only moderately sensitive in demonstrating lymph node metastasis preoperatively, and is inadequate for local staging of patients with endometrial cancer. In ovarian cancer, F-18 FDG PET-CT provides an accurate assessment of the extent of disease, particularly in areas difficult to assess for metastases by CT and MRI such as the abdomen and pelvis, mediastinum, and supraclavicular region. F-18 FDG PET-CT is a sensitive method of detecting pelvic and para-aortic lymph nodal disease in cervical cancer, and appears to be superior to MRI and CT despite the limitations in identifying small foci of disease. In the main, as elsewhere in patients with cancer, the value of PET-CT is in identifying and defining the extent of recurrent disease, in distinguishing between posttreatment fibrosis and recurrence, and possibly in monitoring response to therapy.

full free access: Lessons From the Adjuvant Bevacizumab Trial on Colon Cancer: What Next?



"........Finally, how should we consider the use of antiangiogenic therapy in general in the adjuvant setting? Will VEGF blockade ever suffice when administered as single antiangiogenic agent in combination with chemotherapy, or will we need to combine bevacizumab with other antiangiogenic agents? Although an easy solution at this stage would be to lose interest in the therapeutic potential of antiangiogenic therapy in the adjuvant setting because of these initial disappointing results, the more challenging way forward will require a better understanding of the underlying mechanisms of why bevacizumab treatment differs so much in the adjuvant setting versus the macrometastatic setting. Only by achieving this goal will it be possible to make a more informed decision on this important matter"

Abstract:

Purpose:     Preclinical studies have suggested accelerated tumor growth, local invasion, and distant metastasis after withdrawal of treatment with some antiangiogenic agents. To investigate whether discontinuation of bevacizumab treatment is associated with accelerated disease progression or increased mortality, we retrospectively analyzed five randomized, placebo-controlled phase III studies in 4,205 patients with breast, colorectal, renal, and pancreatic cancer.

Conclusion This retrospective analysis of five placebo-controlled clinical trials does not support a decreased time to disease progression, increased mortality, or altered disease progression pattern after cessation of bevacizumab therapy.

Summary
by: Hazel Burnham
 
CRD Summary: The authors concluded that oestrogen therapy use increased ovarian cancer in a duration-dependent manner; adding progestins appeared to reduce this effect to some extent. The conclusions appeared to be supported by the evidence but the limited search, lack of reporting of review methods and study quality, and reliance upon predominantly observational studies mean that findings should be interpreted with caution.
CRD Commentary: The review question was stated and appropriate inclusion criteria were defined. Limiting the search to English language published studies identified in one database plus references and linked articles may have resulted in the omission of other relevant studies and raised the potential for publication and language bias. However, no evidence of publication bias was found. Methods used to select studies and extract data were not described, so it is not known whether efforts were made to reduce reviewer errors and bias. Study validity was not assessed, so results from these studies and any synthesis may not be reliable.
Other than duration of oestrogen-only therapy/oestrogen plus progestin therapy use, no information was provided about participants. No information was provided about which potential confounders were adjusted for in individual studies. Data were pooled using meta-analysis and heterogeneity was assessed. Studies were predominantly observational and adjustments were made for potential confounders. The authors’ conclusions appeared to be supported by the evidence, but the limited search, lack of reporting of review methods and study quality, and reliance upon predominantly observational studies mean that findings should be interpreted with caution.

full free access: How Research Influences Policy Makers: Still Hazy After All These Years — J. Natl. Cancer Inst. Steven Lewis (author)



"Libraries have been written about the theory and practice of public policy making. Yet, this enormous scholarship has proved insufficient to lift the veil of mystery and idiosyncrasy that shrouds the art of decision making. The heady ambition to turn both clinical practice and health policy into evidence-based bastions of rationalist decision making has been downgraded; the vocabulary is now “evidence-informed,” and the realm of admissible evidence has been greatly expanded to include preferences, political contingencies, and psychology (1). This newfound conceptual modesty and nuance does not suggest that we should abandon efforts to understand decision-making processes and to enhance the role of research-based evidence in policy. It merely confirms the complexity, contingency, and messiness of the terrain............This leads to a second issue: the definition of “use.” The questionnaires simply asked whether the respondents intended to use the brief. We do not know what “use” means.." cont'd

abstract: Indication for oophorectomy during cytoreduction for intraperitoneal metastatic spread of colorectal or appendiceal origin(cytoreductive surgery/HIPEC)



BACKGROUND: The incidence of ovarian metastases at the time of peritoneal carcinomatosis, and the influence of such metastases on survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), are unknown.
METHODS: This retrospective analysis included 194 women subjected to CRS and HIPEC since 2001. The incidence of ovarian metastases, disease-free survival and disease-specific survival were analysed.
RESULTS: The histological diagnosis was colorectal cancer carcinomatosis in 108 patients, peritoneal mucinous carcinomatosis (PMCA) in 23 and disseminated peritoneal adenomucinosis (DPAM) in 63. Ninety-nine patients underwent oophorectomy during the HIPEC procedure. Ovarian metastases were confirmed in at least 52 per cent of the patients. There was a significant difference in disease-free survival between women with or without ovarian metastases in both PMCA and DPAM groups (P = 0·044 and P = 0·010 respectively). No significant differences in survival were found in the group with colorectal cancer carcinomatosis.
CONCLUSION: When peritoneal carcinomatosis of colorectal or appendiceal origin is confirmed, at least 52 per cent of ovaries will have synchronous metastases. Disease-free survival after a HIPEC procedure for PMCA or DPAM is significantly lower in women with ovarian metastases. Oophorectomy during CRS for peritoneal carcinomatosis should be strongly considered.

abstract: Metastatic neoplasms of the ovaries: a clinicopathological study of 97 cases (metastatic breast, GI neoplasms....)



OBJECTIVE: To present the clinicopathological features of metastatic ovarian neoplasms with emphasis in the diagnostic challenge.
METHODS: This is a retrospective study including 97 patients with pathological diagnosis of metastatic ovarian neoplasms, examined during the decade 2000-2009. The gross, microscopical and immunohistochemical characteristics as well as the clinical data (age of the patients, origin of the neoplasm, symptoms, treatment options) and 5-year survival rates were examined.
RESULTS: The mean age of the patients is 55 years (range 26-78 years). 62.89% of the tumors were metastatic from extragenital organs (from stomach 21.65%, breast 15.46%, colon 15.46%, appendix 3.09%, pancreas 2.06%, lung 1.03% and kidney 1.03%, sarcoma 1.03% melanoma 1.03%) and 37.11% tumors originated from the genital tract. The 3-year survival rates ranged from 25.39% for metastatic ovarian neoplasms originating outside the genital tract up to 29.41% for those originating from the genital tract. Tumor immunohistochemistry is a helpful aid in the differential diagnosis mainly between primary mucinous ovarian tumors and metastatic colon cancers and in the recognition of metastatic breast cancers and other neoplasms of the GI tract.
CONCLUSION: The management of metastatic ovarian neoplasms should include specific immunohistochemical methods in order to identify the primary neoplasm site. The differential diagnosis of a pelvic mass should always include metastatic neoplasms of the ovaries.

abstract: Tubal ligation and the risk of ovarian cancer: review and meta-analysis — Hum Reprod Update (serous/mucinous/endometrioid)



BACKGROUND The reduction of ovarian cancer (OC) risk in women with a history of tubal ligation (TL) has been reported repeatedly, mostly on small populations. We have aimed to provide a critical overview of the studies available to date and to conduct a meta-analysis.
METHODS There were 40 relevant studies identified. The studies were divided into two groups for strict and extended meta-analysis, respectively. Subgroup analysis was performed for age, time dependency since TL, histological types of OC and BReast CAncer (BRCA) mutation.
RESULTS Meta-analysis of 13 strictly selected studies showed a reduced risk of epithelial OC by 34%. The protective effect of TL was confirmed even in a subgroup of women 10–14 years after the procedure. The risk reduction was confirmed for the endometrioid (RR = 0.40) and serous (RR = 0.73) cancers but not for mucinous.
CONCLUSIONS The review of relevant articles, as well as the meta-analysis of selected studies, yields consistent data on a significant reduction of OC risk in women who had undergone TL. The results of this meta-analysis should provide an impulse for further research on the etiology of ovarian epithelial cancers, focusing particularly on the importance of retrograde transport of endometrial cells.

summary: Abagovomab: an anti-idiotypic CA-125 targeted immunotherapeutic agent for ovarian cancer phase 111 MIMOSA trial



Abagovomab: an anti-idiotypic CA-125 targeted immunotherapeutic agent for ovarian cancer
Rachel N Grisham​‌1, Jonathan Berek​‌2, Jacobus Pfisterer​‌3 & Paul Sabbatini​‌1
Ovarian cancer remains the leading cause of death due to gynecologic malignancies. Most patients present with advanced disease at the time of diagnosis. Although many have a good initial response to surgical debulking and platinum-based chemotherapy, relapse is common, with the eventual development of chemotherapy resistance. Innovative treatments are needed in the remission setting to prolong the disease-free interval or prevent recurrence. Abagovomab is a murine monoclonal anti-idiotypic antibody (molecular wieght: 165–175 kDa) that functionally imitates the tumor-associated antigen, CA-125. It has been shown to be well tolerated and to induce a sustained immune response in initial Phase I and II clinical trials. An ongoing, double-blind, placebo-controlled, multicenter, Phase III trial (MIMOSA) completed its double-blind period in December 2010 and will compare abagovomab maintenance therapy to placebo, which will definitively determine the efficacy of this immunotherapeutic approach in patients with ovarian cancer.

Effect of Occult Metastases on Survival in Node-Negative Breast Cancer — NEJM



Conclusions

Occult metastases were an independent prognostic variable in patients with sentinel nodes that were negative on initial examination; however, the magnitude of the difference in outcome at 5 years was small (1.2 percentage points). These data do not indicate a clinical benefit of additional evaluation, including immunohistochemical analysis, of initially negative sentinel nodes in patients with breast cancer.

European Journal of Human Genetics - Abstract of article: On the origin and diffusion of BRCA1 c.5266dupC (5382insC) in European populations



"The BRCA1 mutation c.5266dupC was originally described as a founder mutation in the Ashkenazi Jewish (AJ) population. However, this mutation is also present at appreciable frequency in several European countries, which raises intriguing questions about the origins of the mutation. We genotyped 245 carrier families from 14 different population groups (Russian, Latvian, Ukrainian, Czech, Slovak, Polish, Danish, Dutch, French, German, Italian, Greek, Brazilian and AJ) for seven microsatellite markers and confirmed that all mutation carriers share a common haplotype from a single founder individual.............Our results illustrate that (1) BRCA1 c.5266dupC originated from a single common ancestor and was a common European mutation long before becoming an AJ founder mutation and (2) the mutation is likely present in many additional European countries where genetic screening of BRCA1 may not yet be common practice."

Conclusion:
This independent validation study demonstrated similar performance indices to those recently published. However, in this study, HE4 and ROMA did not increase the detection of malignant disease compared with CA125 alone. Although the initial reports were promising, measurement of HE4 serum levels does not contribute to the diagnosis of ovarian cancer

abstract: High prevalence of symptoms associated with ovarian cancer among Australian women



Background:  Symptoms associated with ovarian cancer are often vague and non-specific, such as abdominal bloating and pain. Presently, nothing is known about the prevalence of these symptoms among women in the community.
Aims:  To identify the prevalence and correlates of symptoms associated with ovarian cancer in a nationally representative sample of Australian women. Methods:  Women answered questions about symptoms associated with ovarian cancer via computer-assisted telephone interviews. Binomial regression was used to assess the association between reporting symptoms, demographic characteristics and sexual problems.
Results:  Data on 2235 women aged 18-70 who had not had an oophorectomy or hysterectomy were analysed. Prevalences of symptoms were abdominal bloating 52%, abdominal pain 37%, increased abdominal size 30%, pelvic pain 29%, feeling full quickly 18% and unable to eat normally 15%. One-third of women (32%) reported three or more symptoms, 2% reported all six and 32% of women reported none. Severe symptoms were generally reported by <10% of women reporting symptoms, and symptoms usually persisted for 5 days or less a month. Older women were less likely to report symptoms, as were women who had been pregnant. There was an association between symptoms and sexual difficulties whereby women who reported multiple ovarian cancer symptoms were more likely to report sexual problems.
Conclusions:  There is a high prevalence of ovarian cancer symptoms in the Australian community. Because of this, awareness campaigns will likely impact a large number of women who do not have ovarian cancer.

Define: C-reactive protein (CRP) is a protein found in the blood, the levels of which rise in response to inflammation (an acute-phase protein). ...
en.wikipedia.org/wiki/C-reactive_protein
Abstract

BACKGROUND: Evidence suggests that inflammation may be associated with increased risk of ovarian cancer but there is paucity of studies investigating this association, especially using over-time changes in inflammatory biomarkers.

MATERIALS AND METHODS: We conducted a prospective population-based case-control study nested within the Finnish Maternity Cohort (FMC). Within the FMC, 170 women with ovarian cancer who had donated serum samples to the cohort twice, ≥1 year apart, before cancer diagnoses were identified. One control per case was matched for age, parity and sampling date.

RESULTS: Comparing the highest with lowest tertiles, the odds ratio (OR) of ovarian cancer using the first set of serum samples (mean lag time to cancer diagnosis 9.0 years) was 1.62 [95% confidence interval (CI) 0.93-2.83]. However, analysis conducted using the second set of serum samples donated closer to cancer diagnosis (mean lag time 6.4 years) revealed a significantly increased risk of ovarian cancer comparing extreme tertiles of C-reactive protein (CRP) concentrations; OR 1.96 (95% CI 1.11-3.4). Over time, increases in individuals' CRP concentrations were also associated with increased risk; OR 1.90 (95% CI 1.12-3.23).

CONCLUSION: The results suggest that inflammation may precede ovarian cancer since increasing CRP concentrations, both across tertiles and longitudinally at the individual level, were associated with increased risk.

abstract: A systematic review of gynecological cancer surveillance in women belonging to Hereditary Nonpolyposis Colorectal Cancer (Lynch syndrome) fa



Conclusions.
Currently available published studies on gynecological cancer surveillance in women with HNPCC do not adequately allow for evidence-based clinical decisions. Detection of endometrial cancer or hyperplasia in nonsymptomatic women belonging to a HNPCC family is improved by adding routine endometrial sampling along with transvaginal ultrasound for surveillance visits. No benefit was shown for ovarian cancer surveillance.

Note: tables for survival data (longterm) eg. cell types

"....The Gynecology Tumour Group of our institution has elected to continue to advise the use of CRT in women with stage Ic and II endometrioid and mucinous lesions, and all stage I and II clear cell disease, on the basis of these data and a recently published analysis of histotype-specific outcomes [32]. However, RT will be targeted to the pelvis, with consideration of extending the field to include paraaortic nodes if stage IIc (given the higher rate of occult nodal involvement reported for this stage [26]). RT will be dropped from our prescription for those with serous tumors.
Our findings also bring into question the nonselective surgical and CT approaches that have characterized ovarian cancer care and are of potential clinical importance for those with other tumors, which have been collectively defined by presumed organ of origin rather than underlying biological features"

full free access abstract + full paper: Social and ethical implications of BRCA testing — Ann Oncol



Abstract:
"Oncologists are asked with increasing frequency to counsel their patients with respect to the medical, psychological and social repercussions of genetic testing for cancer susceptibility that may have been prescribed by physicians or carried out through direct-to-consumer tests. This article critically reviews the main ethical and social implications of BRCA testing, focusing on genetic responsibility and genetic discrimination. Genetic responsibility toward oneself and others is a highly debated implication of genetic testing for cancer predisposition that requires broad considerations of the boundaries between individual and community rights and a reappraisal of the notion of autonomy as relational. Physicians’ duty to warn ‘at risk’ relatives can be an ethical quandary, yet confidentiality is key to the patient–doctor relationship. Mutation carriers may be subject to different forms and degrees of genetic discrimination and many individuals at risk have forgone BRCA testing to avoid potential discrimination. The scientific and medical community, together with patients and the public, has actively engaged against genetic discrimination. The legislation in many countries now protects against genetic discrimination by insurance companies and employers. Legal and regulatory issues are not the final answer to discrimination and profound cultural changes are required to create understanding and acceptance of all differences...."

  Note:  pdf file


Conclusions and Emerging Trends in Biomarkers for Ovarian Cancer

"The ultimate aim of effective screening techniques is to bring about a reduction in mortality form ovarian cancer. As early detection continues to be vital in ovarian cancer patients, biomarkers may hold the key to unlocking effective screening strategies for the general population. It is also important to identify screening techniques with low false positive rates and high positive predictive value so that the number of negative surgical interventions can be minimized. Since our currently available single markers are not highly sensitive or specific, a combination of markers may be utilized as a profile for risk assessment. The current problem with screening panels is that the improvement in sensitivity usually correlates with a decrease in specificity, making the target positive predictive value hard to obtain. The multimodal screening profiles of the genetic markers could be utilized in the future for risk assessment, early diagnosis, prognosis and response to therapeutic treatment. Recent literature reports state that the screening is only recommended for the high risk population identified as those with a family history of the disease, women with BRCA1 and BRCA2 mutations, or with hereditary non polyposis colorectal cancer. Recent literature reports also emphasize that the different subtypes of ovarian cancer may have different genetic biomarker expression profiles. Current randomized controlled screening trials are directed towards finding the best molecular and genetic markers for the specific histology of the ovarian tumor with the most impact on reduction in morbidity and mortality. The tumor markers identified in these trials may also lead to novel targets for antitumor therapy."

Abstract/full free access: An evaluation of access to health care services along the rural-urban continuum in Canada



Conclusion

Inequities in access to care along the rural-urban continuum exist and can be masked when evaluation is done at a very large scale with gross indicators of rural-urban. Understanding the relationship between rural-urban and other determinants will help policy makers to target interventions appropriately: to specific demographic, provincial, community, or rural categories.

Conclusions. The randomized trial reported significantly more surgical-site infections than the clinical database. The DGCD reported only 50% of the deep and organ-space infections, and hence, the low-overall agreement indicates a need for more careful database registration.

abstract: Phase II study evaluating consolidation whole abdominal intensity-modulated radiotherapy (IMRT) in patients with advanced ovarian cancer stage FIGO III - The OVAR-IMRT-02 Study



BACKGROUND:
".... Recurrences of the disease occur mostly intraperitoneally. Ovarian cancer is a radiosensitive tumor, so that the use of whole abdominal radiotherapy (WAR) as a consolidation therapy would appear to be a logical strategy. WAR used to be the standard treatment after surgery before the chemotherapy era; however, it has been almost totally excluded from the treatment of ovarian cancer during the past decade because of its high toxicity. Modern intensity-modulated radiation therapy (IMRT) has the potential of sparing organs at risk like kidneys, liver, and bone marrow while still adequately covering the peritoneal cavity with a homogenous dose. Our previous phase I study showed for the first time the clinical feasibility of intensity-modulated WAR and pointed out promising results concerning treatment tolerance. The current phase-II study succeeds to the phase-I study to further evaluate the toxicity of this new treatment. Methods / design: The OVAR-IMRT-02 study is a single-center one arm phase-II trial. Thirty seven patients with optimally debulked ovarian cancer stage FIGO III having a complete remission after chemotherapy will be treated with intensity-modulated WAR as a consolidation therapy. A total dose of 30 Gy in 20 fractions of 1.5 Gy will be applied to the entire peritoneal cavity including the liver surface and the pelvic and para-aortic node regions. Organ at risk are kidneys, liver (except the 1cm-outer border), heart, vertebral bodies and pelvic bones. Primary endpoint is tolerability; secondary objectives are toxicity, quality of life, progression-free and overall survival.

DISCUSSION: Intensity-modulated WAR provides a new promising option in the consolidation treatment of ovarian carcinoma in patients with a complete pathologic remission after adjuvant chemotherapy. Further consequent studies will be needed to enable firm conclusions regarding the value of consolidation radiotherapy within the multimodal treatment of advanced ovarian cancer. Trial registration: NCT01180504.

abstract: Phase II trial of combretastatin A4 phosphate, carboplatin, and paclitaxel in patients with platinum-resistant ovarian cancer



Note: searching blog for A4 will provide further research specific to  clear cell/A4


CONCLUSIONS: The addition of CA4P to paclitaxel and carboplatin is well tolerated and appears to produce a higher response rate in this patient population than if the chemotherapy was given without CA4P. A planned randomised trial will test this hypothesis.

abstract: Indication for oophorectomy during cytoreduction for intraperitoneal metastatic spread of colorectal or appendiceal origin



BACKGROUND: The incidence of ovarian metastases at the time of peritoneal carcinomatosis, and the influence of such metastases on survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), are unknown.
CONCLUSION: When peritoneal carcinomatosis of colorectal or appendiceal origin is confirmed, at least 52 per cent of ovaries will have synchronous metastases. Disease-free survival after a HIPEC procedure for PMCA or DPAM is significantly lower in women with ovarian metastases. Oophorectomy during CRS for peritoneal carcinomatosis should be strongly considered.

PURPOSE: To review the role of adjuvant radiotherapy (RT) in the outcome and recurrence patterns of granulosa cell tumors (GCTs) of the ovary.

CONCLUSION: Ovarian GCTs can be indolent, with patients achieving long-term survival. In our series, adjuvant RT resulted in a significantly longer DFS. Ideally, randomized trials with long-term follow-up are needed to define the role of adjuvant RT for ovarian GCTs.

Promoting genetic literacy: cancer control in the BRCA era - Cutting Edge - Cancer World (including Lynch Syndrome/spectrum of cancers)



Note: worth reading; covers a variety of concerns
 
IN BRIEF
  • Accounting for around 5%–10% of all breast cancers, harmful mutations in BRCA1 or BRCA2 increase a woman’s chance of developing breast cancer over their lifetime by approximately five times compared to the normal population.
  • Carriers of the harmful BRCA1/2 mutations are also approximately 10–30 times more likely to develop ovarian cancer, with these mutations accounting for around 10% of all ovarian cancers.
  • There is no single BRCA mutation, but a wide variety of mutations on these two genes, many of which have yet to be recorded. Only some have been demonstrated to be harmful.
  • BRCA mutations can also raise the risk of other cancers, including gastric, pancreatic, colon and prostate cancer, as well as melanoma and male breast cancer.
  • Other ‘cancer genes’ include mutated APC genes, responsible for familial adenomatous polyposis, which lead to colon cancer, and mutated MLH1, MSH2 MSH6, or PMS2 genes, which are associated with hereditary non-polyposis colon cancer (HNPCC) (Lynch Syndrome), a syndrome that also raises the risk of endometrial (uterine), stomach, ovarian, small bowel (intestinal), urinary tract, liver, and bile duct cancers.

abstract: Healthy eating index and ovarian cancer risk. [Cancer Causes Control. 2011] - PubMed result




The evidence for a role of diet on ovarian cancer prevention remains inconclusive.
While many studies have evaluated individual foods and food groups, the evaluation of a comprehensive dietary quality index for predicting cancer risk has received little attention.
This study investigates the association between the Healthy Eating Index (HEI), which reflects adherence to the current USDA Dietary Guidelines for Americans and ovarian cancer risk in a population-based case-control study in New Jersey. A total of 205 cases and 390 controls completed the Block 98.2 food frequency questionnaire (FFQ) in addition to reporting on potential risk factors for ovarian cancer. FFQ data were then utilized to calculate the HEI score, and cup, ounce, gram, or caloric equivalents for the 12 different food groups comprising the index. In multivariate models, the OR for the highest tertile of the HEI score compared with the lowest (reflecting a better diet compared with a worse diet) was 0.90 (95% CI: 0.55-1.47).
There was limited evidence for a statistically significant association between any of the 12 individual food components and ovarian cancer risk. Based on this study's results, neither individual food groups nor dietary quality showed potential for preventing ovarian cancer.

abstract: A non-BRCA1/2 hereditary breast cancer sub-group defined by aCGH profiling of genetically related patients (BRCAx)



Germline mutations in BRCA1 and BRCA2 explain approximately 25% of all familial breast cancers.

Despite intense efforts to find additional high-risk breast cancer genes (BRCAx) using linkage analysis, none have been reported thus far.

Here we explore the hypothesis that BRCAx breast tumors from genetically related patients share a somatic genetic etiology that might be revealed by array comparative genomic hybridization (aCGH) profiling.

As BRCA1 and BRCA2 tumors can be identified on the basis of specific genomic profiles, the same may be true for a subset of BRCAx families. Analyses used aCGH to compare 58 non-BRCA1/2 familial breast tumors (designated BRCAx) to sporadic (non-familiar) controls, BRCA1 and BRCA2 tumors. The selection criteria for BRCAx families included at least three cases of breast cancer diagnosed before the age of 60 in the family, and the absence of ovarian or male breast cancer.

Hierarchical cluster analysis was performed to determine sub-groups within the BRCAx tumor class and family heterogeneity. Analysis of aCGH profiles of BRCAx tumors indicated that they constitute a heterogeneous class, but are distinct from both sporadic and BRCA1/2 tumors. The BRCAx class could be divided into sub-groups. One subgroup was characterized by a gain of chromosome 22. Tumors from family members were classified within the same sub-group in agreement with the hypothesis that tumors from the same family would harbor a similar genetic background. This approach provides a method to target a sub-group of BRCAx families for further linkage analysis studies.

abstract: Clear cell carcinoma of the ovary: A report from the first Ovarian Clear Cell Symposium, June 24th, 2010 (plus blogger's commentary)



Blogger's Notes: with the exception of the 2 mutations mentioned, there is nothing new in this abstract;  social media can overcome past issues with patient accrual


OBJECTIVES: Recent literature has highlighted histological types of ovarian carcinoma as distinct diseases, each with unique clinical and molecular features. Historically, the diagnosis of ovarian clear cell carcinoma (CCC) has been of concern to both patients and physicians due to reports that CCC is associated with a worse prognosis than the more common serous type of ovarian carcinoma (HGSC). This review discusses the unique features of ovarian CCC.

METHODS: In June of 2010, a group of researchers and clinicians convened in Vancouver to review and discuss the clinical, pathological, molecular, and treatment-related features of CCC.

RESULTS: CCC is the second most common type of ovarian epithelial cancer, representing 5-25% of ovarian carcinomas. It is characterised by its association with endometriosis, and frequent mutations of ARID1A and PIK3CA. Low-stage CCC appears to have a better outcome than stage matched HGSC, while the opposite is true for high-stage disease, suggesting that the current standard treatments applied to HGSC (high grade serous) are ineffective for CCC.

CONCLUSIONS: Ovarian CCC is highly distinct from HGSC, and a clearer understanding of the basic biology of this disease is needed. Alternative therapies should be explored: irradiation and targeting disease-specific molecular markers should be examined in greater detail. Finally, novel approaches to clinical trial design are needed due to the smaller numbers of patients affected.

abstract: Surgical staging of early stage epithelial ovarian... [Gynecol Oncol. 2011] - PubMed result



Note: positive lymph node findings upgrade staging from early stage to advanced stage; full access is by subscription ($$$)


OBJECTIVES: The objectives of this study were to determine the adequacy of surgical staging performed on surgically treated epithelial ovarian cancer (EOC) patients with apparent early stage disease and to determine if receipt of surgical staging had an influence on survival.
METHODS: Detailed surgical staging information was collected from medical records for 721 patients diagnosed between 1998 and 2000 with EOC. Patients resided in California or New York and were identified through population-based cancer registries.
RESULTSNearly 90% of patients had removal of the omentum and evaluation of bowel serosa and mesentery but only 72% had assessment of retroperitoneal lymph nodes and the majority of patients did not receive biopsies of other peritoneal locations. Only lymph node assessment (as well as node assessment combined with washings and omentectomy) had a statistically significant association with improved survival. The 5-year survival for women with node sampling was 84.2% versus 69.6% for those without this surgical procedure, and patients who did not have lymph node assessment had nearly twice the risk of death as those who did. When patients were stratified by receipt of chemotherapy, lack of node sampling had an effect only on patients who also had no chemotherapy (adjusted HR=2.2, CI=1.0-4.5).
CONCLUSIONS: The results of this population-based study confirm the prognostic importance of surgical staging for women with EOC, and the important role of gynecologic oncologists in treating these patients. Adjuvant chemotherapy does not appear to further improve survival for those women who receive adequate surgical staging.

"Learning about hereditary cancer may influence an individual's self-concept, which otherwise represents a complex but stable cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements-the first related to feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing one's privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales and demonstrates its applicability in different Western populations."

Abstract

There is evidence that hormone replacement therapy (HRT) may both stimulate and inhibit breast cancers, giving rise to a spectrum of activities, which are frequently hard to understand. Here we summarise the evidence for these paradoxical effects and, given the current data, attempt to give an indication where it may or may not be appropriate to prescribe HRT.It is clear that administration of oestrogen-progestin (E-P) and oestrogen alone (E) HRT is sufficient to stimulate the growth of overt breast tumours in women since withdrawal of HRT results in reduction of proliferation of primary tumours and withdrawal responses in metastatic tumours. E-P, E including tibolone are associated with increased local and distant relapse when given after surgery for breast cancer. For women given HRT who do not have breast cancer the only large randomised trial (WHI) of E-P or E versus placebo has produced some expected and also paradoxical results. E-P increases breast cancer risk as previously shown in observational studies. Risk is increased, particularly in women known to be compliant. Conversely, E either has no effect or reduces breast cancer risk consistent with some but not all observational studies. Two observational studies report a decrease or at least no increase in risk when E-P or E are given after oophorectomy in young women with BRCA1/2 mutations. Early oophorectomy increases death rates from cardiovascular and other conditions and there is evidence that this may be reversed by the use of E post-oophorectomy. HRT may thus reduce the risk of breast cancer and other diseases (e.g., cardiovascular) in young women and increase or decrease them in older women.
