abstract: Cochrane review - Optimal primary surgical treatment for advanced epithelial ovarian cancer



Abstract

BACKGROUND:

Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is one of the most important prognostic factors for survival of women with epithelial ovarian cancer. An optimal outcome of cytoreductive surgery remains a subject of controversy to many practising gynae-oncologists. The Gynaecologic Oncology group (GOG) currently defines 'optimal' as having residual tumour nodules each measuring 1 cm or less in maximum diameter, with complete cytoreduction (microscopic disease) being the ideal surgical outcome. Although the size of residual tumour masses after surgery has been shown to be an important prognostic factor for advanced ovarian cancer, it is unclear whether it is the surgical procedure that is directly responsible for the superior outcome that is associated with less residual disease.

OBJECTIVES:

To evaluate the effectiveness and safety of optimal primary cytoreductive surgery for women with surgically staged advanced epithelial ovarian cancer (stages III and IV).To assess the impact of various residual tumour sizes, over a range between zero and 2 cm, on overall survival.

MAIN RESULTS:

There were no RCTs or prospective non-RCTs identified that were designed to evaluate the effectiveness of surgery when performed as a primary procedure in advanced stage ovarian cancer.We found 11 retrospective studies that included a multivariate analysis that met our inclusion criteria. Analyses showed the prognostic importance of complete cytoreduction, where the residual disease was microscopic that is no visible disease, as overall (OS) and progression-free survival (PFS) were significantly prolonged in these groups of women. PFS was not reported in all of the studies but was sufficiently documented to allow firm conclusions to be drawn.When we compared suboptimal (> 1 cm) versus optimal (< 1 cm) cytoreduction the survival estimates were attenuated but remained statistically significant in favour of the lower volume disease group There was no significant difference in OS and only a borderline difference in PFS when residual disease of > 2 cm and < 2 cm were compared (hazard ratio (HR) 1.65, 95% CI 0.82 to 3.31; and HR 1.27, 95% CI 1.00 to 1.61, P = 0.05 for OS and PFS respectively).There was a high risk of bias due to the retrospective nature of these studies where, despite statistical adjustment for important prognostic factors, selection bias was still likely to be of particular concern. Adverse events, quality of life (QoL) and cost-effectiveness were not reported by treatment arm or to a satisfactory level in any of the studies.

AUTHORS' CONCLUSIONS:

During primary surgery for advanced stage epithelial ovarian cancer all attempts should be made to achieve complete cytoreduction. When this is not achievable, the surgical goal should be optimal (< 1 cm) residual disease. Due to the high risk of bias in the current evidence, randomised controlled trials should be performed to determine whether it is the surgical intervention or patient-related and disease-related factors that are associated with the improved survival in these groups of women. The findings of this review that women with residual disease < 1 cm still do better than women with residual disease > 1 cm should prompt the surgical community to retain this category and consider re-defining it as 'near optimal' cytoreduction, reserving the term 'suboptimal' cytoreduction to cases where the residual disease is > 1 cm (optimal/near optimal/suboptimal instead of complete/optimal/suboptima

LIFE Before Death : The Lancet Oncology - documentary/commentary



Genesis of the LIFE Before Death project lay in remarks from WHO. “The project co-producer Mike Hill and I read a 2009 WHO statement saying that 600 million people worldwide were going to suffer in their lifetime from untreated pain due to a lack of access to medicinal opiates”, explains Australian documentary maker Sue Collins. “We found that a very alarming statistic”, she added. Here are three more alarming statistics: more than 5 billion people worldwide have no access to essential pain medicines; this year 3·6 million people will die with untreated severe pain from cancer and AIDS; and 99·9% of these deaths will be in low-income and middle-income countries.

The predicted truncation from a (ovarian) cancer-associated variant of the MSH2 initiation codon alters activity of the MSH2-MSH6 mismatch repair complex



Abstract

Lynch syndrome (LS) is caused by germline mutations in DNA mismatch repair (MMR) genes. MMR recognizes and repairs DNA mismatches and small insertion/deletion loops. Carriers of MMR gene variants have a high risk of developing colorectal, endometrial, ovarian, and other extracolonic carcinomas. We report on an ovarian cancer patient who carries a germline MSH2 c.1A>C variant which alters the translation initiation codon. Mutations affecting the MSH2 start codon have been described previously for LS-related malignancies. However, the patients often lack a clear family history indicative of LS and their tumors often fail to display microsatellite instability, a hallmark feature of LS...."(technical)

Prognostic Role of Vitamin D Status and Efficacy of Vitamin D Supplementation in Cancer Patients: A Systematic Review - the Oncologist



Abstract  

Background. Whether or not hypovitaminosis D can influence the prognosis of cancer patients and whether or not vitamin D (vitD) supplementation improves outcome remain controversial.


Conclusion. Hypovitaminosis D seems to be associated with a worse prognosis in some cancers, but vitD supplementation failed to demonstrate a benefit in prostate cancer patients. The currently available evidence is insufficient to recommend vitD supplementation in cancer patients in clinical practice.

Note: per reference, one study included -  ovarian cancer

EvidenceUpdates - Strategies to identify the lynch syndrome among patients with colorectal cancer: a cost-effectiveness analysis. (focus on women/risk reduction strategies) - abstract



"..... At current rates of germline testing, screening, and prophylactic surgery, the strategies reduced deaths from colorectal cancer by 7% to 42% and deaths from endometrial and ovarian cancer by 1% to 6%....."  

CONCLUSION: Widespread colorectal tumor testing to identify families with the Lynch syndrome could yield substantial benefits at acceptable costs, particularly for women with a mutation associated with the Lynch syndrome who begin regular screening and have risk-reducing surgery. The cost-effectiveness of such testing depends on the participation rate among relatives at risk for the Lynch syndrome.

abstract: Comparing diagnostic delay in cancer: a cross-sectional study in three European countries with primary care-led health care systems (UK, Netherlands, Sweden)



Conclusions. A large-scale study comparing cancer delays in European countries and based on primary care-held records is feasible but would require supplementary sources of data in order to maximize information on demographic variables, the cancer stage at diagnosis and treatment details. Such a large-scale study is timely and desirable since our findings suggest systematic differences in the way cancer is managed in the three countries.

Continuing Medical Education

Abstract

Method
Selective review of the literature.


Results
COCs suppress gonadotropin secretion and thereby inhibit follicular maturation and ovulation. Their correct use is associated with 0.3 pregnancies per 100 women per year, their typical use, with 1 pregnancy per 100 women per year (Pearl index). COCs have effects on the cardiovascular and hemostatic systems as well as on lipid and carbohydrate metabolism. When given in the presence of specific risk factors, they significantly increase the likelihood of cardiovascular disease and thromboembolism. Women with persistent human papilloma virus (HPV) infection who take COCs are at increased risk of developing invasive cervical cancer. On the other hand, COCs lower the cumulative incidence of endometrial and ovarian cancer by 30% to 50%, and that of colorectal cancer by 20% to 30%. Other malignancies seem to be unaffected by COC use.


Conclusion
As long as personal and familial risk factors are carefully considered, COCs constitute a safe, reversible, and well-tolerated method of contraception.

MicroRNA Processing and Binding Site Polymorphisms Are Not Replicated in the Ovarian Cancer Association Consortium



Background: Single nucleotide polymorphisms (SNP) in microRNA-related genes have been associated with epithelial ovarian cancer (EOC) risk in two reports, yet associated alleles may be inconsistent across studies.

Results:
After adjustment for European ancestry, no overall association was observed between any of the analyzed SNPs and EOC risk.

Conclusions: Common variants in these evaluated genes do not seem to be strongly associated with EOC risk.

Impact: This analysis suggests earlier associations between EOC risk and SNPs in these genes may have been chance findings, possibly confounded by population admixture. To more adequately evaluate the relationship between genetic variants and cancer risk, large sample sizes are needed, adjustment for population stratification should be carried out, and use of imputed SNP data should be considered

RANZCOG College Statement on prophylactic oophorectomy in older women undergoing hysterectomy for benign disease: Is the evidence sufficient to change practice?



Conclusion:  A survey of gynaecologists revealed that few currently appear to adhere to the College Statement regarding prophylactic oophorectomy at the time of hysterectomy for benign disease. High quality evidence regarding either harm or benefit following retention of ovaries after menopause is lacking. Nevertheless, dialogue between clinicians and patients on this topic is important.

Markman M.

Cancer Treatment Centers of America, Eastern Regional Medical Center, Philadelphia, PA, USA.

Abstract

Pegylated liposomal doxorubicin (PLD) has become a major component in the routine management of epithelial ovarian cancer. The drug is frequently employed as a single agent in the platinum-resistant setting, and recently reported data reveal the superiority of the combination of PLD plus carboplatin, compared with the platinum drug plus paclitaxel, in delaying the time to disease progression in women with recurrent (potentially platinum-sensitive) disease. Current research efforts involving PLD in ovarian cancer are focusing on adding novel targeted drugs to this cytotoxic agent. The utility of such approaches in the platinum-resistant population, compared with the sequential administration of single agents active in this setting, remains to be determined.

Frank words about breast screening - Open Medicine - Analysis and Comment



"......As recently observed in the New England Journal of Medicine, we should “work to prevent vested interests from being granted the loudest voices in health care.”2 The vested interests in what has been termed “the mammography wars”2 are clearly those in the imaging industry, those involved directly in screening programs, and even those in the not-for-profit sector, whose fundraising capacity is enhanced by a public committed to fighting breast cancer.
It is reasonable for women to choose to be screened, but only if they are completely informed about the probability of benefit versus the probability of harm. For 2000 women aged 40–49 who undergo screening for 10 years, the benefit is much smaller in terms of avoiding death from breast cancer than is the harm arising from over-diagnosis and unnecessary treatment for breast cancer, to say nothing of the increased rates of mastectomy associated with screening.22,23 These issues are not widely known to the general public. After over 20 years of involvement in the screening controversy I can only conclude that this is information few want to hear and many want to suppress."

Glossary | The Cochrane Collaboration (worth bookmarking)



examples:

Adverse effect search for term
An adverse event for which the causal relation between the drug/intervention and the event is at least a reasonable possibility. The term ‘adverse effect’ applies to all interventions, while ‘adverse drug reaction’ (ADR) is used only with drugs. In the case of drugs an adverse effect tends to be seen from the point of view of the drug and an adverse reaction is seen from the point of view of the patient.See also: Adverse event, Side effect Also called: Adverse reaction
Baseline characteristics search for term
Values of demographic, clinical and other variables collected for each participant at the beginning of a trial, before the intervention is administered.
Causal effect search for term
An association between two characteristics that can be demonstrated to be due to cause and effect, i.e. a change in one causes the change in the other. Causality can be demonstrated by experimental studies such as controlled trials (for example, that an experimental intervention causes a reduction in mortality). However, causality can often not be determined from an observational study.

Molecular Test Aids in Identifying Cancers of Unknown Origin - Medscape (pathology/molecular diagnostic test - 15 different cancer types...)



".....The identity of most tumors can be determined "with confidence" by clinicians with histologic, clinical, and radiographic findings, say the study authors, led by James P. Grenert, MD, from the Department of Pathology at UCSF. "However, when tumors are poorly differentiated or metastatic with no clear primary, identifying the tissue of origin is difficult," they write.
Immunohistochemical stains may or may not be helpful in identifying the tumor origin. Molecular testing of tumors is an additional means of characterizing these tumors, the authors say.
TOO is the only molecular diagnostic test for cancer tissue of origin cleared by the US Food and Drug Association, the manufacturer notes. It is limited to identifying 15 types of tumor tissues: bladder, breast, colorectal, gastric, testicular germ cell, kidney, hepatocellular, nonsmall-cell lung, non-Hodgkin's lymphoma, melanoma, ovarian, pancreas, prostate, thyroid, and sarcoma. These 15 tumor types represent 90% of all cancers, the company points out....."cont'd

RID: Preventing "C.diff" - Clostridium difficile



AHRQ: Health Care: 20 Tips to Help Prevent Medical Errors: Patient Fact Sheet



conference notice: (Human Genome Meeting - Sydney) HGM 2012 • Scientific Program



draft agenda

(adverse event) abstract: Inadvertent cystotomy at laparoscopic hysterectomy – Sydney West Advanced Pelvic Surgery (SWAPS)



Conclusion: 
Inadvertent cystotomy is a recognised complication at hysterectomy. The rate in the SWAPS unit is comparable to that of other published series. Overall, there has been a decline in the rate of bladder injury, which appears attributable to more experience gained with an acquisition of increased skill levels and improved techniques.

Predictive Factors in Relapsed Ovarian Cancer for Complete Tumor Resection



"Results:

Overall, 177 consecutive patients (pts) were analyzed. The median age at first diagnosis was 55 years (range, 23-83 years). The complete tumor resection rate was 44.6%. Predictive factors that correlated with an adverse surgical outcome in terms of residual tumor were ascites <500 ml (Odds ratio, OR=0.3; 95% Confidence interval, CI=0.1-0.8 p<0.05), tumor involvement of the small bowel (OR=0.22; 95% CI=0.07-0.71 p<0.05), tumor spread in the upper abdomen (OR=0.33; 95% CI=0.1-0.9 p<0.05) and platinum resistance (OR=0.1, 95% CI=0.06-0.5 p<0.01).

Serous tumor histology (OR=5.8) appeared to have a protective effect. Age and initial FIGO stage were of no predictive significance.

Conclusion:

Platinum-sensitive patients without ascites, no intestinal tumor involvement, tumor restricted to middle and lower abdomen, and of serous papillary histology have significantly higher complete tumor resection rates. Prospective studies are warranted to evaluate the predictive value of these factors."

Note: worth paying attention to the stats

full free access: Individualized Cost-Effectiveness Analysis



Summary Points

Cost-effectiveness analyses typically express their principal results as incremental cost-effectiveness ratios (ICERs).
ICERs are useful in making decisions for allocation of resources at a population level, but typical ICER measures have shortcomings when used for individual decisions.
For the same ICER, the cost-effectiveness may vary among individuals because not everyone assigns the same priorities to specific outcomes, shares the same attitudes toward risk, or faces the same distribution of expected outcomes.
ICER information can be enhanced by providing additional metrics that individualize cost-effectiveness analyses.
These metrics include the per person net benefit and cost, subgroup ICER estimates for observed measured sources of heterogeneity, and distributions of outcomes and costs for unknown or unmeasured sources of heterogeneity.

Risk for CRC in Lynch Syndrome May Be Lower Than We Thought: Prevalence of Alterations in DNA Mismatch Repair Genes in Patients With Young-Onset Colorectal Cancer - Medscape Oncology



"Clearly, as we develop more accurate estimates of risks associated with specific mutations, personalized screening methods and intervals will need to be further clarified among those with LS. Although it appears that the overall risk for CRC among those with LS may be lower than previously thought, there are likely to be specific mutations that confer a higher risk and require more intensive screening protocols."

European Journal of Cancer : Primary versus secondary cytoreduction for epithelial ovarian cancer: A paired analysis of tumour pattern and surgical outcome



Conclusions Secondary cytoreduction due to EOC appears to be associated with significantly lower optimal tumour debulking rates compared to primary setting, since the disease tends to recur in patterns less accessible to complete resection such as gastrointestinal serosa, mesentery and upper abdomen. By maximal surgical effort, tumour residuals significantly correlate between primary and secondary cytoreduction. No other predictors of surgical outcome or tumour-pattern could be identified.

Poly(ADP-Ribose) Polymerase Inhibition Synergizes with 5-Fluorodeoxyuridine but not 5-Fluorouracil in Ovarian Cancer Cells-abstract



"5-Fluorouracil (5-FU) and 5-fluorodeoxyuridine (FdUrd, floxuridine) have activity in multiple tumors, and both agents undergo intracellular processing to active metabolites that disrupt RNA and DNA metabolism." "These findings underscore differences in the cytotoxic mechanisms of 5-FU and FdUrd and suggest that combining FdUrd and PARP inhibitors may be an innovative therapeutic strategy for ovarian tumors."

Factors Associated with Altered Long-Term Well-Being After Prophylactic Salpingo-Oophorectomy Among Women at Increased Hereditary Risk for Breast and Ovarian Cancer-abstract




Proteomic biomarkers in combination with CA 125 for detection of epithelial ovarian cancer using prediagnostic serum samples from the prostate, lung, colorectal, and ovarian (PLCO) cancer screening trial



RESULTS:

CA 125 levels were elevated (≥35 U/mL) in 61.5% of 65 patients who had CA 125 data available from samples that were collected <12 months before cancer diagnosis; however, levels of the additional 7 biomarkers were not different between cases and the 3 control groups individually or combined. Two panels that combined CA 125 and the 7 biomarkers failed to improve the sensitivity of CA 125 alone.

CONCLUSIONS:

In contrast to earlier findings from analyzes of postdiagnostically collected sera, the addition of 7 biomarkers to CA 125 did not improve sensitivity for preclinical diagnosis beyond CA 125 alone.

" The strongest evidence for reproductive disease due to asbestos is in regard to ovarian cancer. Unfortunately, effects on fertility and the developing fetus are under-studied. The possibility of other asbestos-induced health effects does exist. These include brain-related tumors, blood disorders due to the mutagenic and hemolytic properties of asbestos, and peritoneal fibrosis. It is clear from the literature that the adverse properties of asbestos are not confined to the pulmonary system."

Cochrane review: Short versus long duration infusions of paclitaxel for any advanced adenocarcinoma.



OBJECTIVES:

To assess the effectiveness and toxicity of short versus long infusions of paclitaxel for any advanced adenocarcinoma.

"Adverse events were not comprehensively reported for any of the other comparisons. Outcomes were incompletely documented and QoL outcomes were not reported in any of the trials. The strength of the evidence is weak in this review as it is based on meta analyses of very few trials or single trial analyses and all trials were at moderate risk of bias and two were published in abstract form only."

irrespective of location, C. difficile is an ongoing and unresolved issue (both hospital/non-hospital acquired) and in particular for cancer patients;

it seems the SARS cases of the past have not impacted the 'lessons-not-learned' category and yet people continue to die due to lapses in policy amongst other issues/concerns, patient safety efforts (eg. handwashing...) still need to be addressed (obviously)

 Highlights


► Ovarian endometriosis is known to transform into ovarian cancer, but its etiology is not clarified.
► A stressful microenvironment within the endometriotic cyst may lead to cancer development.
► Ovarian clear cell carcinoma has unique gene expressions, which may serve as a molecular marker.
► Carcinogenic microenvironment affects the phenotype, character and gene expression of a cancer.
► We might be able to develop new treatment based on the analysis of the influence of microenvironment.
