Cytokine profiling of ascites at primary surgery identifies an interaction of tumor necrosis factor-α and interleukin-6 in predicting reduced progression-free survival in epithelial ovarian cancer

OBJECTIVES Epithelial ovarian cancer (EOC) typically presents with advanced disease. Even with optimal debulking and response to adjuvant chemotherapy, the majority of patients will have disease relapse. We evaluated cytokine and chemokine profiles in ascites at primary surgery as biomarkers for progression-free survival (PFS) and overall survival (OS) in patients with advanced EOC. METHODS Retrospective analysis of patients (n =70) who underwent surgery at Roswell Park Cancer Institute between 2002 and 2012, followed by platinum-based chemotherapy. RESULTS The mean age at diagnosis was 61.8 years, 85.3% had serous EOC, and 95.7% had stage IIIB, IIIC, or IV disease. Univariate analysis showed that ascites levels of tumor necrosis factor (TNF)-α were associated with reduced PFS after primary surgery. Although the ascites concentration of interleukin (IL)-6 was not by itself predictive of PFS, we found that stratifying patients by high TNF-α and high IL-6 levels identified a sub-group of patients at high risk for rapid disease relapse. This effect was largely independent of clinical prognostic variables. CONCLUSIONS The combination of high TNF-α and high IL-6 ascites levels at primary surgery predicts worse PFS in patients with advanced EOC. These results suggest an interaction between ascites TNF-α and IL-6 in driving tumor progression and resistance to chemotherapy in advanced EOC, and raise the potential for pre-treatment ascites levels of these cytokines as prognostic biomarkers. This study involved a small sample of patients and was an exploratory analysis; therefore, findings require validation in a larger independent cohort.

Use of common analgesics is not associated with ovarian cancer survival

Background: Use of analgesics has been associated with lower risk of ovarian cancer, but, to date, very few studies have explored the association between analgesics and ovarian cancer survival. Methods: We examined the relationship between self-reported prediagnostic use of aspirin, ibuprofen, and acetaminophen and overall survival (OS), progression-free survival (PFS), ascites at the time of primary treatment, and persistence of disease after primary treatment among 699 women diagnosed with epithelial ovarian carcinoma. The associations between use of these medications and OS and PFS were estimated using Cox proportional hazards models. We utilized unconditional logistic regression models to estimate associations between medication use and presence of ascites and persistence of disease. Results: Prediagnostic intake of aspirin, both low-dose and regular-dose, ibuprofen, and acetaminophen was not associated with any of the outcomes of interest. Conclusions: Our results indicate a lack of association between prediagnostic intake of selected analgesics and OS, PFS, presence of ascites at the time of primary treatment, and persistence of disease after primary treatment. Impact: Prediagnostic intake of analgesics may not be associated with ovarian cancer outcomes. Cancer Epidemiol Biomarkers Prev; 24(8); 1291–4. ©2015 AACR.

Oral Contraceptive Use and Reproductive Characteristics Affect Survival in Patients With Epithelial Ovarian Cancer: A Cohort Study.

Objectives Prognostic risk factors influencing survival in patients with epithelial ovarian cancer (EOC) include tumor stage, grade, histologic subtype, debulking, and platinum status. Little is known about the impact of hormonal milieu and reproductive factors before cancer diagnosis on clinical outcome. We sought to evaluate whether oral contraceptive (OC) use carries any prognostic significance on overall survival (OS) in patients with EOC. Methods Newly diagnosed patients with EOC, fallopian tube, and primary peritoneal cancers between 1982 and 1998 were prospectively evaluated with a comprehensive epidemiologic questionnaire. A retrospective chart review was performed to abstract clinicopathologic data, including OS. A Kaplan-Meier analysis was performed to compare survival across various exposures. A Cox regression model was used to compute adjusted hazards ratios (aHRs) and 95% confidence intervals (CIs). Results We identified 387 newly diagnosed cancers with evaluable information in this cohort. Decreased risk of death was observed in women who reported prior use of OC (aHR, 0.79; 95% CI, 0.58–1.09), previous pregnancy (aHR, 0.77; 95% CI, 0.57–1.04), or a live birth (aHR, 0.81; 95% CI, 0.60–1.08) after adjusting for age at diagnosis, stage, and histologic subtype. Oral contraceptive use was associated with a crude reduced risk of death (HR, 0.55; 95% CI, 0.42–0.72), with reported median OS of 81 months in OC users versus 46 months in nonusers. Patients who reported a single live birth experienced the largest potential survival advantage (aHR, 0.61; 95% CI, 0.39–0.94). Oral contraceptive use and prior pregnancy were associated with improved survival across all strata. Conclusions Oral contraceptive use may have lasting effects on epithelial ovarian tumor characteristics conferring favorable prognosis. Putative mechanisms that affect tumor biology include complex interactions between ovarian cells, host immune cells, and hormonal microenvironment during carcinogenesis. Future efforts should be directed to determine the role of reproductive factors in antitumor immunity.

Evaluation of Metachronous Breast and Endometrial Cancers: Preroutine and Postroutine Adjuvant Tamoxifen Use.

Background The time interval between diagnoses of breast cancer (BC) and endometrial cancer (EC) is not well established in women with metachronous primary tumors. We sought to examine this interval and identify associations with treatment-related and clinicopathologic factors. Methods We identified 141 patients who developed both cancers during 1966 to 2013. Patients were divided into 2 groups: group 1, BC first, and group 2, EC first. Subanalysis performed of group 1 (59 patients) stratified around adjuvant tamoxifen use: pre-1990 BC diagnosis and post. Results Fifty-nine and 82 patients were in groups 1 and 2, respectively. The mean time interval was comparable (76 vs 74 months, P = 0.861). Subanalysis divided group 1 into pre- (n = 27) and post- (n = 32) 1990 and resulted in different mean time intervals between diagnosis of metachronous cancers (106 vs 50 months, respectively [P = 0.042]). Median progression-free survival (PFS) and overall survival (OS) for EC were longer in the pre group (PFS, 51 vs 26 months [P = 0.169]; OS, 59 vs 27 months [P = 0.190]). Median PFS and OS for BC were also longer in this group (PFS, 147 vs 109 months [P = 0.005]; OS, 166 vs 114 months [P < 0.001]). Conclusions Our data indicate the mean time interval between the diagnosis of EC and BC was approximately 6 years. Disease-specific EC survival was worse for patients with a previous diagnosis of BC. Stratification around implementation of tamoxifen use shows comparable grade and stage but different time interval and survival, suggesting resulting effects from adjuvant therapy for BC. These results are useful in counseling women at risk.BACKGROUND The time interval between diagnoses of breast cancer (BC) and endometrial cancer (EC) is not well established in women with metachronous primary tumors.

Evaluation of satisfaction with work–life balance among U.S. Gynecologic Oncology fellows: A cross-sectional study

To characterize the state of satisfaction with work–life balance (WLB) among gynecologic oncology fellows in training, risk factors for dissatisfaction, and the impact of dissatisfaction on career plans. A cross-sectional evaluation of gynecologic oncology fellows was performed using a web-based survey. Demographic data, fellowship characteristics, and career plans were surveyed. The primary outcomes were satisfaction with WLB and career choices. p < 0.05 was used as a test for significance. Regression analysis was used to estimate prevalence ratios (PRs) for various potential risk factors for dissatisfaction. Of 52.5% responding fellows, 22.2% were satisfied with WLB, but 83.3% would be physicians again and 80.3% would select gynecologic oncology again. Satisfaction with WLB was significantly associated with age (PR = 0.70, 95% CI: 0.54–0.91), working fewer than 80 h per week (PR = 4.35, 95% CI: 1.34–14.10), and fatigue (PR = 0.31, 95% CI: 0.12–0.75). Career and WLB satisfaction were not associated with gender, marital status, and whether or not the fellow is a parent. Those satisfied with WLB planned to work an average of 3.5 years longer than those who were not (p < 0.05). Gynecologic oncology fellows are not generally satisfied with their WLB, although this does not alter their overall career or specialty satisfaction. Satisfaction with WLB predicts a longer post-fellowship career. Further studies are needed to determine the workforce impact of this lack of perceived balance.
