Medical News: Cancer Biomarkers Missing in Action - Ovarian Cancer - Medscape

With a handful of possible exceptions, Diamandis wrote, "very few, if any, molecules have been identified that are expressed only by a cancer tissue but not by the corresponding normal tissue."
Cancer biomarkers are missing in action despite the availability of "highly sophisticated and powerful technologies" to discover them, as well as large investments, Diamandis wrote, adding that the last biomarker approved by the FDA -- in 2009 -- was HE4 protein, indicated for monitoring recurrence but not early detection of ovarian cancer."

• Note that this commentary documents the hazards of reports on promising biomarkers for cancer screening.



• The author points out that one of the major problems is finding biomarkers released in significant amounts from asymptomatic (usually small) tumors, but not from normal tissues.

media article: Initial Trials on New Ovarian Cancer Tests (blood) Exhibit Extremely High Accuracy

Blogger's Note:
media reporting issues = watch the word 'extremely' (94 patients in study); comment on symptoms/early stage;

also note the research comment regarding lack of access to ovarian cancer patients/study ?? (needs 500 pts)

 ..........................................................................................................................
“The caveat is we don’t currently have 500 patients with the same type of ovarian cancer, so we’re going to look at other types of ovarian cancer,” said Fernandez. “It’s possible that there are also signatures for other cancers, not just ovarian, so we’re also going to be using the same approach to look at other types of cancers. We’ll be working with collaborators in Atlanta and elsewhere.”

comments in the media item:
In addition to having a relatively low prevalence ovarian cancer is also asymptomatic in the early stages. Therefore, if further testing confirms the ability to accurately detect ovarian cancer by analyzing metabolites in the serum of women, doctors will be able detect the disease early and save many lives.

JCO (Special Issue) Overview: Host Factors and Cancer Outcome

"A solitary focus on tumor-related factors may explain some of the
failures of clinical translations of preclinical discoveries, which often
take place in systems (eg, the cell culture) that do not involve host
influences. There is growing evidence that it is necessary to go beyond
the cell into the whole organism to fully understand the biology of
cancer and its treatment. In the clinic, we are constantly reminded that
the cancer cell does not exist in isolation in the controlled environment
that is possible in the laboratory—it exists within a complex host
that interacts with both the cancer cell and the treatments that are used
to target that cancer cell. It is our hope that this special issue of Journal
of Clinical Oncology will stimulate future basic and translational research
that will facilitate the incorporation of these complex tumor,
treatment, and host factor interactions to optimize the care provided
to our patients."

Continental Divide? The Attitudes of US and Canadian Oncologists on the Costs, Cost-Effectiveness, and Health Policies Associated With New Cancer Drugs

From the Sunnybrook Odette Cancer Center; University of Toronto; Keenan Research Center in the Li Ka Shing Knowledge Institute, St. Michael's Hospital; Institute for Clinical Evaluative Sciences, Toronto; McMaster University; Juravinski Cancer Center at Hamilton Health Sciences, Hamilton; Peel Regional Cancer Center, Mississauga, Ontario, Canada; University of Michigan School of Medicine, Ann Arbor, MI; Charles Sammons Cancer Center, Baylor University Medical Center, Dallas, TX; and the Center for the Evaluation of Value and Risk in Health, Institute for Clinical Research and Health Policy Studies, Tufts Medical Center, Boston, MA.


ABSTRACT

Purpose Oncologists in the United States and Canada work in different health care systems, but physicians in both countries face challenges posed by the rising costs of cancer drugs. We compared their attitudes regarding the costs and cost-effectiveness of medications and related health policy.

Methods Survey responses of a random sample of 1,355 United States and 238 Canadian medical oncologists (all outside of Québec) were compared.

Results Response rate was 59%. More US oncologists (67% v 52%; P < .001) favor access to effective treatments regardless of cost, while more Canadians favor access to effective treatments only if they are cost-effective (75% v 58%; P < .001). Most (84% US, 80% Canadian) oncologists state that patient out-of-pocket costs influence their treatment recommendations, but less than half the respondents always or frequently discuss the costs of treatments with their patients. The majority of oncologists favor more use of cost-effectiveness data in coverage decisions (80% US, 69% Canadian; P = .004), but fewer than half the oncologists in both countries feel well equipped to use cost-effectiveness information. Majorities of oncologists favor government price controls (57% US, 68% Canadian; P = .01), but less than half favor more cost-sharing by patients (29% US, 41% Canadian; P = .004). Oncologists in both countries prefer to have physicians and nonprofit agencies determine whether drugs provide good value. 

(blogger's usual take (based on abstract): and patients in the determination process ??)

 






Conclusion Oncologists in the United States and Canada generally have similar attitudes regarding cancer drug costs, cost-effectiveness, and associated policies, despite practicing in different health care systems. The results support providing education to help oncologists in both countries use cost-effectiveness information and discuss drug costs with their patients.

Abstract: Cervical manifestation of a borderline type ovarian cancer with pseudomyxoma peritonei - a case report

Note: mucinous cell type is a cell type found in numerous organs including colon/rectum Abstract: Borderline tumours of the ovary (BOTs) are rare tumour entities that do not show any destructive or invasive growth in the majority of cases, even though they can display characteristics of malignant tumours The mucinous subtype can also originate from the appendix, and ovarian metastases can mimic primary ovarian BOTs, often accompanied by peritoneal manifestation in terms of pseudomyxoma peritonei. In cases where a concomitant appendiceal tumour is present, it may prove difficult to determine the primary tumour. This report describes a special case of BOT with a specific example of the complexity of the differential diagnosis of pseudomyxoma peritonei. Especially the case was simultaneously linked to appendiceal and ovarian cancer. Moreover, this case was exceptional for its unusual manifestation of BOT in the cervix.

Recurrent Ovarian Cancer: Use of Contrast-enhanced CT and PET/CT to Accurately Localize Tumor Recurrence and to Predict Patients’ Survival1 — Radiology

Abstract

Purpose: To compare accuracy and interobserver variability in the detection and localization of recurrent ovarian cancer with contrast material–enhanced (CE) computed tomography (CT) and positron emission tomography (PET)/CT and determine whether imaging findings can be used to predict survival.

Conclusion: Preliminary data suggest that CE CT and PET/CT may have similar accuracy in detection of recurrent ovarian cancer. Tumor size, number, and SUVmax may have potential as prognostic biomarkers for patients with recurrent ovarian cancer.

Casting light on 25-hydroxyvitamin D deficiency in ovarian cancer: A study from the NHANES (National Health and Nutrition Examination Surveys)

Abstract

Objectives

Ecological studies have long described a higher incidence of ovarian cancer in more extreme latitudes, where sun exposure, and presumably vitamin D exposure, is lower. Basic science studies have also noted polymorphisms of the vitamin D receptor in ovarian cancers. The aim of this study is to examine the relationship of serum vitamin D to ovarian cancer.

Conclusions

Prevalent ovarian cancer cases have lower serum 25-hydroxyvitamin D (25[OH]D) than the general population. Deficiency in vitamin D may provide an etiologic link between the long-known ecologic findings regarding latitude and the basic science noting polymorphisms in the vitamin D receptor.

SGO White Paper Ovarian Education Campaign [INTRODUCTORY PARAGRAPH-Herzog/Coleman] Project I-Background, Screening & Surveillance

Note: this journal requires subscription ($$$)

 Abstract

Ovarian cancer is a heterogeneous, rapidly progressive, highly lethal disease of low prevalence. The etiology remains poorly understood. Numerous risk factors have been identified, the most prominent involving an inherited predisposition in 10% of cases. Women with germline mutations associated with Hereditary Breast/Ovarian Cancer and Lynch syndromes have dramatically elevated risks (up to 46% and 12%, respectively). Risk-reducing salpingo-oophorectomy is the best method to prevent ovarian cancer in these high-risk women. Significant risk reduction is also seen in the general population who use oral contraceptives. Since up to 89% patients with early-stage disease have symptoms prior to diagnosis, increased awareness of the medical community may facilitate further workup in patients who otherwise would have had a delay. Despite enormous effort, there is no proof that routine screening for ovarian cancer in either the high-risk or general populations with serum markers, sonograms, or pelvic examinations decreases mortality. Further evaluation is needed to determine whether any novel biomarkers, or panels of markers, have clinical utility in early detection. Prospective clinical trials have to be designed and completed prior to offering of any of these new diagnostic tests. CA125 is currently the only biomarker recommended for monitoring of therapy as well as detection of recurrence. This commentary provides an overview on the background, screening and surveillance of ovarian cancer.

Objective To identify risk factors for the presence of a non-invasive lesion of the fallopian tube in women with a BRCA1 or BRCA2 mutation (abstract)

Objective

To identify risk factors for the presence of a non-invasive lesion of the fallopian tube in women with a BRCA1 or BRCA2 mutation.

Conclusion

The prevalence of tubal p53 signature and TIC (tubal intra-epithelial carcinoma)  increases with age at salpingectomy and with BMI. Oral contraceptive use is associated with a decrease in the prevalence of TICs.

Partners of long-term gynaecologic cancer survivors: Psychiatric morbidity, psychosexual outcomes and supportive care needs (abstract)

Objective

To describe long-term psychological morbidity, unmet supportive care needs, positive changes, sexual outcomes and relationship satisfaction in partners of gynaecologic cancer survivors, as compared with respective survivors.

Method

Self-report measures were administered to a cross-sectional sample of 68 partners recruited via patient survivors.

Conclusion

The majority of partners reported excellent sexual outcomes and little perceived change since the survivors' diagnosis. The association between unmet needs and psychological morbidity suggests a useful target for further intervention. Despite methodological limitations, these data are novel and present a starting point for further investigation to improve outcomes for survivors and partners.

The National Cancer Database report on advanced-stage epithelial ovarian cancer: Impact of hospital surgical case volume on overall survival and surgical treatment paradigm (abstract)

Objective

To examine the effect of hospital procedure volume and other prognostic variables on overall survival outcome and likelihood of receiving standard recommended care among patients with advanced-stage epithelial ovarian cancer.

Conclusions

Hospital ovarian cancer surgical volume ≥ 21 cases/year is associated with a higher likelihood of patients with Stage IIIC/IV epithelial ovarian cancer receiving standard treatment (surgery followed by adjuvant chemotherapy). Even after adjusting for treatment paradigm and other factors, hospital volume ≥ 21 cases/year was significantly predictive of improved overall survival outcome.

Hospice enrollment for terminally ill patients with gynecologic malignancies: Impact on outcomes and interventions (abstract)

Objective 

To determine survival and interventions for patients with non-curative gynecologic malignancies based on supportive care enrollment.

  
Conclusions
While retrospective reviews evaluating hospice are challenging, our data suggest no detrimental impact on survival for hospice patients. Continued evaluation for patients at the end-of-life is necessary in order to optimize resource utilization.

pilot program - Drug mishap reporting system created for consumers - Canadian Medical Association Journal

Note: the article does not mention until the final statements that this is a pilot project NOR does the website



The new national medication incident reporting system is the first of its kind to directly engage Canadian consumers

http://safemedicationuse.ca/report/index.html

"Health care practitioners and hospitals have been reporting medication incidents using similar tools for years, but there’s never been a formal mechanism to collect incident reports from consumers," says Bonnie Salsman, project lead for the website, which was developed with support from Health Canada.


In the past, if a consumer wanted to report a medication mistake, they had to use a tool designed for health care workers, or else ask a medical practitioner to report the incident on their behalf.


"It wasn’t a consumer-friendly process. It was really difficult for people to get their concerns heard without doing a considerable amount of footwork first," says Salsman. "That there were still patients who took the initiative to report incidents using the practitioner reporting system showed us how helpful a consumer tool would be."


The website offers Canadians a simplified form to report any medication incident involving the use of prescription and nonprescription drugs, natural health products, imported products, or devices used to administer medicine. Consumers can report incidents that occur at any stage in the prescribing, dispensing, administration, or monitoring of a medication. They can also offer their own suggestions on how to avoid similar mishaps in future....cont'd

According to the 2008 Commonwealth Fund International Health Policy Survey of Sicker Adults, 1 in 10 Canadians with health problems have reported receiving the wrong medication or doses when filling a prescription or when hospitalized in the last two years, while nearly 1 in 7 said they had experienced a medication error in the past two years.
The Institute for Safe Medication Practices Canada will continue to monitor the success of the website’s pilot phase in the coming months, and expects to report preliminary results to Health Canada this fall.

ISMP Canada will:

• review your report
• look for system problems that could cause errors to happen
• prepare recommendations that are designed to prevent mistakes with medication
• send recommendations about medication safety to health professionals and consumers
• provide consumer-focused information and tips about medication safety on the SafeMedicationUse.ca website

ISMP Canada will not:

• investigate a complaint on your behalf with an organization or health professional that is responsible for an error in care
• investigate the actions of individual practitioners
• report (for disciplinary purposes) the incident to professional authorities responsible for regulating the practice of health professionals
• release or publish any information that could identify the reporter of an incident, a patient, a health professional or an organization involved in an incident

How to Avoid a Heart Attack: Putting It All Together -Journal of the American Osteopathic Association

Note: this is not specific to treatment-related cardiovascular concerns

Conclusion
The central question posed in the letter to the editor by Juhl et al2 is whether supplements of vitamins E and C and the B vitamins have demonstrated an evidence-based reduction in patients' cardiovascular risk. Unfortunately, the authors' criticism of the perceived deficiencies of a previously published study1 does not constitute evidence to support their position; it serves only to point out those perceived flaws.

Multiple meta-analyses and reviews of published medical literature have convincingly established that there are few, if any, objective, evidence-based, well-designed trials to support the use of supplements of vitamins E or C or those in the B family to reduce risk of cardiovascular events. Furthermore, I am unaware of any study that advocates the use of these supplements to help patients or to rejuvenate our ailing medical delivery system.

If Dr Juhl and his coauthors2 seek to establish the medical value of these supplements, I would recommend that they design, participate in, and publish a study to establish their yet unproven hypothesis. Until such a goal is accomplished, my opinion (shared by researchers at the Mayo Clinic,3 the Cleveland Clinic,5 the AHRQ,12 and the American Heart Association19) is that published evidence clearly does not support the use of vitamins E, C, B6, B9, or B12 to improve patients' cardiovascular health.

A prospective study of dietary acrylamide intake and the risk of breast, endometrial, and ovarian cancers — Cancer Epidemiology, Biomarkers & Prevention

WHO website: What is acrylamide?

Abstract

Background
Acrylamide is a probable human carcinogen formed during cooking of many common foods. Epidemiological studies of acrylamide and breast cancer risk have been null; however, positive associations with ovarian and endometrial cancers have been reported. We studied acrylamide intake and risk of breast, endometrial, and ovarian cancers in a prospective cohort study.

Methods
We assessed acrylamide intake among 88,672 women in the Nurses' Health Study using food frequency questionnaires administered every four years. Between 1980 and 2006 we identified 6301 cases of invasive breast cancer, 484 cases of invasive endometrial adenocarcinoma, and 416 cases of epithelial ovarian cancer. We used Cox proportional hazards models to study the association between acrylamide and cancer risk.

Results
We found no association between acrylamide intake and breast cancer overall or according to estrogen and progesterone receptor status. We found an increased risk of endometrial cancer among high acrylamide consumers (adjusted relative risk [RR] for highest versus lowest quintile=1.41, 95% CI: 1.01-1.97, p-value for trend=0.03). We observed a non-significant suggestion of increased risk for ovarian cancer overall (RR 1.25, CI: 0.88-1.77, p-trend=0.12), with a significantly increased risk for serous tumors (RR 1.58, CI: 0.99-2.52, p-trend=0.04). Associations did not differ by smoking status.

Conclusions
We observed no association between acrylamide and breast cancer. Risk of endometrial cancer and possibly ovarian cancer was greater among high acrylamide consumers.

Impact
This is the second prospective study to report positive associations with endometrial and ovarian cancers. These associations should be further evaluated to inform public health policy.

Background: To explore the influence of ovarian cancer histotype on the effectiveness of adjuvant radiotherapy (RT).

Methods: A review of a population-based experience included all referred women with no reported macroscopic residuum following primary surgery who underwent adjuvant platin-based chemotherapy (CT), with or without sequential RT, and for whom it was possible to assign histotype according to the contemporary criteria.

Results: Seven hundred and three subjects were eligible, of these 351 received RT. For those with apparent stage I and II tumors, the cohort with clear cell (C), endometrioid (E), and mucinous (M) disease who additionally received RT exhibited a 40% reduction in disease-specific mortality and a 43% reduction in overall mortality.

Conclusions: The curability of those with stage I and II C-, E-, and M-type ovarian carcinomas was enhanced by RT-containing adjuvant therapy. This benefit did not extend to those with stage III or serous tumors. These findings necessitate reassessments of the role of RT and of the nonselective surgical and CT approaches that have characterized ovarian cancer care.

How to follow-up patients with epithelial ovarian cancer
Miller, Rowan E; Rustin, Gordon JS

Abstract

Purpose of review: Despite optimal primary treatment most patients with advanced epithelial ovarian cancer will relapse. This review discusses the controversy regarding surveillance and the timing of treatment for recurrent disease.

Recent findings: Routine physical examination has a limited role in the detection of recurrent ovarian cancer. PET/computed tomography (CT) has been shown to be useful in detecting small volume disease not apparent on traditional imaging in patients with suspected recurrence based on symptoms and/or rising CA125. The results of PET/CT can alter treatment plans and have particular use in guiding site-directed therapy. The benefits of early detection and systemic treatment of recurrence are now in doubt following the presentation of the MRC/EORTC CA125 surveillance trial. The impact on survival of secondary cytoreductive surgery requires more investigation.

Summary: Uncertainties remain in the surveillance and timing of treatment for relapsed disease. Patients should be informed of these uncertainties and become involved in decisions regarding their follow-up.

Participatory Evidence: Opportunities & Threats

Download MP3 | Request a Transcript  |  ShareThis In medicine, evidence separates modern scientific treatment from Folk Art. Medical evidence is acquired through observation, experimentation, and information sharing in scientific peer-reviewed journals. When new treatments are used, millions of patients around the world provide additional evidence for what works and what doesn't.
In our new world of instant information exchange and empowered patients, how are clinicians and empowered patients challenging traditional ways to collect, evaluate, and publish evidence? What evidence should we trust? This program, moderated by Peter Frishauf, frames the issues and proposes at least one solution to sorting through the evidence puzzle.

abstract: DNA copy numbers profiles in affinity-purified ovarian clear cell carcinoma (research/pathology)

Note: in research

CONCLUSIONS: This study provides the first high resolution, genome-wide view of DNA copy number alterations in ovarian CCC. The findings provide a genomic landscape for future studies aimed at elucidating the pathogenesis and developing new target-based therapies for CCCs.


Abstract

PURPOSE: Advanced ovarian clear cell carcinoma (CCC) is one of the most aggressive ovarian malignancies, in part because it tends to be resistant to platinum-based chemotherapy. At present, little is known about the molecular genetic alterations in CCCs except that there are frequent activating mutations in PIK3CA. The purpose of this study is to comprehensively define the genomic changes in CCC based on DNA copy number alterations.

EXPERIMENTAL DESIGN: We performed 250K high-density single nucleotide polymorphism array analysis in 12 affinity-purified CCCs and 10 CCC cell lines. Discrete regions of amplification and deletion were also analyzed in additional 21 affinity-purified CCCs using quantitative real-time PCR.

RESULTS: The level of chromosomal instability in CCC as defined by the extent of DNA copy number changes is similar to those previously reported in low-grade ovarian serous carcinoma but much less than those in high-grade serous carcinoma. The most remarkable region with DNA copy number gain is at chr20, which harbors a potential oncogene, ZNF217. This discrete amplicon is observed in 36% of CCCs but rarely detected in serous carcinomas regardless of grade. In addition, homozygous deletions are detected at the CDKN2A/2B and LZTS1 loci. Interestingly, the DNA copy number changes observed in fresh CCC tissues are rarely detected in the established CCC cell lines.

CONCLUSIONS: This study provides the first high resolution, genome-wide view of DNA copy number alterations in ovarian CCC. The findings provide a genomic landscape for future studies aimed at elucidating the pathogenesis and developing new target-based therapies for CCCs.

abstract: FDG-PET/CT in advanced ovarian cancer staging: Value and pitfalls in detecting lesions in different abdominal and pelvic quadrants compared with laparoscopy

CONCLUSION:

Our results suggest that PET/CT may prove a useful tool for pre-surgical staging of ovarian cancer with a sensitivity and specificity of 78 and 68%, respectively. However, it may be used in combination with laparoscopy for better results. PET/CT showed an adequate correlation between SUVmax values and laparoscopy findings of lesions >5mm, but a high rate of false negative results in lesions <5mm such as in carcinomatosis. PET/CT should be used carefully in early stage disease, with low risk of peritoneal infiltration, because of high rate of false positive results, to avoid unnecessary therapy procedures.

abstract: Messenger RNA expression and methylation of candid tumor suppressor genes and risk of ovarian cancer (serous cell type)

Note: edited stats for ease of reading (italics)

Abstract

To investigate the association of expression and promoter methylation of tumor-suppressor genes with risk of ovarian cancer, we conducted a case-control study of 102 patients with serous epithelial ovarian cancer and 100 patients without ovarian cancers.

We measured mRNA expression levels (by real-time reverse transcription polymerase chain reaction) and methylation status (by methylation-specific polymerase chain reaction) of five candidate genes (BRCA1, BRCA2, hMLH1 (Lynch Syndrome gene) , MGMT, and DNMT3B) in tumors from the cases and normal ovaries from the controls.

We found that mRNA expression levels of the five genes were decreased in tumors than in normal ovaries with 0.39-fold for BRCA1, 0.25-fold for BRCA2, 0.42-fold for hMLH1, 0.45-fold for MGMT, and 0.87-fold for DNMT3B, calculated by the 2(-DeltaDeltaCT) method.

Ovarian cancer risk (odds ratios, ORs) was associated with low expression of all genes

2.95 for BRCA1,

3.65 for BRCA2,

5.25 for hMLH1 (one of the Lynch Syndrome genes)

However, methylation status was not associated with gene expression levels in the tumors, except for hMLH1 whose mean (+/- SD) gene expression was significantly lower in methylated (13.0 +/- 7.6) than in unmethylated (31.2 +/- 44.8) tumors (P < 0.001).

We concluded that low mRNA expression of these tumor-suppressor genes, likely due to molecular mechanisms in addition to the promoter methylation in some instances, may be a biomarker for ovarian cancer risk in this study population. Larger studies are needed to validate our findings.

Abstract/free full access: Scope of nanotechnology in ovarian cancer therapeutics

Note: in research/technical

Abstract
This review describes the use of polymer micelle nanotechnology based chemotherapies for ovarian cancer. While various chemotherapeutic agents can be utilized to improve the survival rate of patients with ovarian cancer, their distribution throughout the entire body results in high normal organ toxicity. Polymer micelle nanotechnology aims to improve the therapeutic efficacy of anti-cancer drugs while minimizing the side effects.

Conclusions
Polymer micelle nanotechnology has demonstrated that nanoparticles are capable of loading anti-cancer drugs which can be specifically targeted to tumors through the conjugation of tumor specific antibody/moiety. Multi-functional polymer micelles, including nanogels/magnetic based micelles, possess characteristics which could improve ovarian cancer therapy. These formulations have capabilities of MRI visible targeting, targeted photodynamic therapy, thermosensitive therapy and luminescence/nearinfrared/
multi-model imaging properties, which will allow tracking and monitoring of nanoformulations and accumulated drug(s) at the tumor site during the therapy procedure.

Quality of life and meaning of life: measuring the unmeasurable

Note: see Einstein's quote at the top of this blog

Abstract

Quality of life (QoL) in medicine and in oncology is an accepted parameter for the evaluation of the benefit of treatments. Scientific methods exist to assess QoL measures in clinical trials. However, many components of the person that are properly humane and determine the patient’s attitude towards the disease are not measured by current criteria. Based on clinical experience, the author considers that a shift in knowledge and in doctors’ attitudes is required to also include non-measurable parameters in the doctor-patient relationship.

Conclusion
The majority of older newly diagnosed cancer patients underwent the recommended cancer treatment but partial or complete cancer treatment refusal in older newly diagnosed cancer patients was not uncommon.

abstract: Ranked importance of outcomes of first-line versus repeated chemotherapy among ovarian cancer patients

Purpose  

To examine the importance of possible outcomes of first-line versus repeated chemotherapy to ovarian cancer patients and to compare doctors' treatment intentions with patients' beliefs about cure.

Methods  

Women with newly diagnosed (74) or relapsed (48) ovarian cancer were prospectively followed over 2 years. The level of importance they ascribed to four chemotherapy outcomes and their beliefs about cure were assessed. Their doctors independently specified intent of successive treatments.

Results  

Approximately half (54%) of newly diagnosed ovarian cancer patients (65% with residual disease >2 cm and 49% with no or ≤2 cm residual disease) ranked ‘tumour shrinkage (or decrease in blood levels of CA125)’ as ‘most important’ during first-line chemotherapy. Approximately two thirds (65–70%) of all women whose disease had relapsed also ranked ‘tumour shrinkage’ as ‘most important’ during repeated chemotherapy. Few women (<8%) rated symptom relief or absence of side-effects as most important. While both patients' and doctors' belief about cure decreased over successive treatments, patients grew more optimistic relative to doctors over time. Women's reports of advice by doctors about cure were consistent with doctors' stated intents for repeat chemotherapy. However, discordance between doctors' actual treatment intent and patients' beliefs about cure increased from 24% at first-line to 83% by fourth-line chemotherapy.

Conclusions  

Women prioritise tumour response as the most important outcome of chemotherapy for ovarian cancer. This priority predominates in women with residual and relapsed disease despite declining likelihood of cure. Women may still hope for a cure while acknowledging their doctor's advice that their disease is incurable.

Correlation of extreme drug resistant assay results and progression-free survival following intraperitoneal chemotherapy for advanced ovarian cancer (Oncotech assay)

Abstract

The aim of this study was to determine if in vitro extreme drug resistance (EDR) to platinum and/or taxane chemotherapy was predictive of patient response to intraperitoneal (I.P.) chemotherapy in patients with stage III or recurrent epithelial ovarian cancer (EOC).

Fifty-six patients were retrospectively identified who underwent optimal cytoreductive surgery for primary or recurrent eOC and then received at least three cycles of either intravenous (I.V.) or I.P. chemotherapy with platinum and paclitaxel-based chemotherapy. EDR to platinum and/or paclitaxel was determined using a commercially available assay (Oncotech, Inc., Tustin, CA).

The primary outcome measure was progression-free survival (PFS).

Twenty-nine (52%) patients received I.P. chemotherapy and 27 (48%) received I.V. chemotherapy. The patients were well matched in terms of age, stage, grade and histology. Ten (35%) patients in the I.OP. arm and ten (37%) patients in the I.V. arm showed EDR to either platinum and/or paclitaxel. Median PFS for all I.P. chemotherapy patients was 23 months, compared with 13 months for those receiving I.V. chemotherapy (p = 0.04).

Patients with EDR to platinum and/or taxane who underwent I.V. chemotherapy had a median PFS of 13.5 months, whereas those who underwent I.P. treatment had a median PFS of 15 months (p = 0.69). Median overall survival had not been reached at the time of analysis. No significant difference in PFS was noted between patients who underwent I.P. and those who underwent I.V. chemotherapy when EDR was predicted to either platinum or paclitaxel or both. These data suggest that the decision to offer I.P. chemotherapy, with the attendant increase in morbidity, in the setting of EDR to platinum and/or taxane chemotherapy, may not be beneficial. 

Prospective studies, preferably analyzing platinum or taxane EDR individually, are required to validate these observations.

Weekly paclitaxel in the treatment of recurrent ovarian cancer - abstract

Abstract:

Weekly paclitaxel is a highly active and well tolerated regimen that is increasingly being adopted for the treatment of relapsed ovarian cancer. This regimen is usually administered at 80-90 mg/m(2)/week, and the use of a 1 h infusion helps minimize myelosuppression. When compared with the 3-weekly schedule, weekly paclitaxel is better tolerated, with a reduced frequency of grade 3-4 toxic effects. Single-agent weekly paclitaxel for relapsed ovarian cancer yields response rates in the range of 20-62%; however, response duration can be short. Responses to weekly paclitaxel have been observed in patients whose tumors are resistant to 3-weekly paclitaxel. The level of activity of weekly paclitaxel for relapsed disease has led to its detailed evaluation in the first-line setting, and interest has been enhanced by the results of a Japanese Gynecological Oncology Group study that demonstrated a survival advantage for weekly paclitaxel compared with 3-weekly paclitaxel in combination with carboplatin as initial treatment. The enhanced efficacy of weekly paclitaxel may be due to greater drug exposure, a direct antiangiogenic effect, or both. Current research topics include the combination of weekly paclitaxel with molecular-targeted agents and the use of molecular profiling to better select patients for treatment.

Second-line treatment of first relapse recurrent ovarian cancer.Australian and New Zealand Journal of Obstetrics and Gynaecology abstract

Review Article

cytoreductive surgery • intraperitoneal chemotherapy • ovarian cancer
ABSTRACT

First-line therapy of advanced ovarian cancer involves primary cytoreductive surgery and adjuvant systemic chemotherapy. Progression of incompletely resected disease or recurrence after cytoreduction is inevitable. The approach to second-line treatment is ill-defined and chemotherapy remains the conventional approach, with surgery being reserved in some patients to debulk or palliate symptoms. Increasing evidence suggests that secondary cytoreduction improves progression-free and overall survival. This approach may be appropriate in selected patients. Intraperitoneal chemotherapy delivered in the adjuvant setting postoperatively has been shown to be more effective than systemic chemotherapy in advanced ovarian cancer after primary surgery. However, its use has not been well accepted and has not been adopted in secondary surgery. Hyperthermic intraperitoneal chemotherapy delivered intraoperatively during surgery has been of clinical interest and may prove to be efficacious and advantageous. The support of the gynaecological cancer medical and surgical community to embrace the efforts and assist in the recruitment of appropriate patients into randomised trials of first relapse recurrent ovarian cancer will provide answers to questions and establish evidence that would impact the care of ovarian cancer patients.

Prognostic Relevance of Uncommon Ovarian Histology (abstract) multinational study

 Note:   and stage 1/11??;  see abstract for authors

Prognostic Relevance of Uncommon Ovarian Histology in Women With Stage III/IV Epithelial Ovarian Cancer.

BACKGROUND::
The prognostic relevance of uncommon epithelial ovarian cancer (EOC) histological subtypes remains controversial. The Gynecologic Cancer InterGroup (GCIG) initiated this meta-analysis to assess the relative prognosis of women with a diagnosis of rare EOC histologies from completed, prospectively randomized studies performed by cooperative GCIG study groups.

METHODS::
Studies eligible for analysis included first-line treatment of at least 150 patients with stage III/IV EOC treated with a platinum/taxane-based regimen. Collaborating groups were to provide patient-level data. Serous acted as the reference histology, and a proportional hazards model was used to estimate the relative rate of progression or death.

RESULTS::
Data on 8704 women with stage III/IV EOC from 7 randomized trials were included in these analyses. Two hundred twenty-one patients (2.5%) had clear cell carcinoma; 264 (3.0%), mucinous; and 36 (0.4%), transitional cell. The mean age of patients with serous histology was greater than those with mucinous (4.1 years) and clear cell (2.6 years, P < 0.001). Mucinous, clear cell, and transitional cell tumors were more likely to be completely resected than serous (P < 0.05). When controlling for age and residual disease, mucinous and clear cell tumors had shorter times to progression (hazards ratio [HR], 2.1; 95% confidence interval [CI], 1.8-2.4 and HR, 1.6; 95% CI, 1.4-1.9, respectively) and death (HR, 2.7; 95% CI, 2.3-3.1 and HR, 2.2; 95% CI, 1.8-2.6, respectively) compared with serous. The median overall survival for serous, clear cell, mucinous, and endometrioid histologies were 40.8, 21.3, 14.6, and 50.9 months.

CONCLUSIONS:: Mucinous and clear cell carcinomas are independent predictors of poor prognosis in stage III/IV EOC. Studies targeting these rare histological subtypes are warranted and will require significant intergroup collaboration.

abstract : Whole blood-derived miRNA profiles as potential new tools for ovarian cancer screening : British Journal of Cancer

Conclusion:

Our proof-of-principle study strengthens the hypothesis that neoplastic diseases generate characteristic miRNA fingerprints in blood cells. Still, the obtained OvCA-associated miRNA pattern is not yet sensitive and specific enough to permit the monitoring of disease progression or even preventive screening. Microarray-based miRNA profiling from peripheral blood could thus be combined with other markers to improve the notoriously difficult but important screening for OvCA.

Upstaging pathologic stage I ovarian carcinoma based on dense adhesions is not warranted: A clinicopathologic study of 84 patients originally originally classified as FIGO stage II

Note: very interesting study, albeit abstract

 

Abstract

BACKGROUND: 

FIGO stage II ovarian cancer comprises 8% of ovarian cancers. It is a common but not universal practice to upstage densely adherent pathologic stage I tumors to stage II. FIGO guidelines are not clear, and data supporting this practice are sparse.

METHODS:

We retrospectively reviewed patients with stage II ovarian cancer and grouped them based upon histologic evidence of extraovarian extension. Tumors densely adherent to extraovarian structures but without histologic tumor outside the ovary were considered pathologic stage I. All others were considered surgical-pathologic stage II. Three histologic patterns of extraovarian tumor involvement were identified.

RESULTS:

Eighty-four patients were studied. Twenty-four patients had pathologic stage I disease and 60 had histologic evidence of extraovarian pelvic spread and were surgical-pathologic stage II. The 5-year survival for stage I was 100%, and the median survival was not reached. The 5-year survival for those with surgical-pathologic stage II disease was 56.8% and the median survival was 73months. There were no differences observed based upon pattern of extraovarian spread. The survival difference between pathologic stage I and surgical-pathologic stage II was significant (p<0.001). There were no differences seen in 5-year survival among surgical-pathologic stage II patients with serous, endometrioid or clear cell histologies (64.5%, 64.8% and 64.3% respectively).

CONCLUSION:

These retrospective data suggest that the practice of upstaging densely adherent pathologic stage I tumors to stage II may not be warranted. Cell type is not a prognostic factor in stage II.

Characteristics and survival associated with ovarian cancer diagnosed as first cancer and ovarian cancer diagnosed subsequent to a previous cancer

Abstract

Objective:
To examine the risk of subsequent primary ovarian cancer among women diagnosed previously with cancer (subsequent cohort) and to compare demographic and tumor characteristics affecting overall survival of these women and women diagnosed with first primary ovarian cancer (index cohort).


Methods: 
We identified the two cohorts of women using the 1973-2005 Surveillance, Epidemiology and End Results (SEER) result data. We calculated relative risk of subsequent primary ovarian cancer and estimated 5-year risks of dying (hazard-ratios) after diagnosis of the first or subsequent primary ovarian cancer in the two cohorts, respectively using Cox modeling.


Results:
Women diagnosed with index cancers of the corpus uteri, colon, cervix, and melanoma at age younger than 50 had increased risk of ovarian cancer within 5 years after diagnosis (p<0.05); young breast cancer survivors had continued risk beyond 20 years. In 5-year follow-up survival analysis, the factors associated with a better survival (p<0.05) were similar in both cohorts and included more recent diagnosis; localized or regional disease; age <50 years at diagnosis; and being white versus black. A lower risk of dying from mucinous, endometrioid, or non-epithelial tumors than from serous was seen after 15 months (p<0.01), or after 32 months from diagnosis of the index and subsequent cohorts, respectively. (clear cell??)


Conclusions:
Age, stage, and histology affect ovarian cancer survival. The increased risk of ovarian cancer over time, especially among breast and colon cancer survivors who are less than 50 years of age, suggests common etiologies and necessitates careful surveillance by health care providers and increased survivors awareness through educational efforts.
