RESUMO
In the single-arm non-interventional OTILIA study, patients with newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage IIIB-IV ovarian cancer received bevacizumab (15 mg/kg every 3 weeks for up to 15 months) and standard carboplatin-paclitaxel. The primary aim was to assess safety and progression-free survival (PFS). Subgroup analyses according to age were prespecified. The analysis population included 824 patients (453 aged <70 years, 371 aged ≥70 years). At data cutoff, the median bevacizumab duration was 13.8 months. Grade ≥3 adverse events (AEs), serious AEs, and AEs leading to bevacizumab discontinuation were more common in older than younger patients, whereas treatment-related AEs were less common. Median PFS was 19.4 months, with no clear difference according to age (20.0 vs. 19.3 months in patients <70 vs. ≥70 years, respectively). One-year OS rates were 92% and 90%, respectively. Mean change from baseline in global health status/quality of life showed a clinically meaningful increase over time. In German routine oncology practice, PFS and safety were similar to reported randomized phase 3 bevacizumab trials in more selected populations. There was no notable reduction in effectiveness and tolerability in patients aged ≥70 years; age alone should not preclude use of bevacizumab-containing therapy. ClinicalTrials.gov: NCT01697488.
RESUMO
UNLABELLED: The aim of this study was to investigate the influence of sex hormone levels on tumor biology and patients' outcome in ovarian cancer. PATIENTS AND METHODS: One hundred and six patients with ovarian cancer were enrolled into this prospective study. Serum and ascites samples were obtained intraoperatively. Concentrations of estradiol, FSH, LH and prolactin were measured and correlated with parameters of tumor biology, such as FIGO stage, tumor spread and postoperative tumor residual mass. Patients with primary ovarian cancer were compared to patients with recurrent disease. Influence factors on progression-free survival and overall survival were analyzed using the Kaplan-Meyer method. RESULTS: Serum FSH concentrations were significantly higher and estradiol concentrations in ascites were significantly lower in patients with recurrent disease. According the multivariate analysis, only FSH level in ascites was seen to be an independent prognostic factor for patients' survival. CONCLUSION: High level of FSH in the ascites provides prognostic information in patients with ovarian cancer and is inversely correlated with patients' survival.

Epidemiological and cell culture studies indicate that ovarian carcinoma growth is dependent on estrogen stimulation. However, possibly due to the lack of a reliable biomarker that helps to select patients according to prognostically relevant estrogen receptor (ER) levels, clinical trials using anti-estrogenic therapeutics in ovarian carcinoma have had inconsistent results. Therefore, we tested if ER expression analysis by a quantitative method might be useful in this regard in formalin-fixed paraffin-embedded (FFPE) tissue. In a study group of 114 primary ovarian carcinomas expression of estrogen receptor 1 (ESR1) mRNA was analyzed using a new method for RNA extraction from FFPE tissue that is based on magnetic beads, followed by kinetic PCR. The prognostic impact of ESR1 mRNA expression was investigated and compared to ERalpha protein expression as determined by immunohistochemistry. In univariate survival analysis the expression level of ESR1 mRNA was a significant positive prognostic factor for patient survival (hazard ratio (HR) 0.230 (confidence interval (CI) 0.102-0.516), P=0.002). ERalpha protein expression was correlated to ESR1 mRNA expression (P=0.0001); however, ERalpha protein expression did not provide statistically significant prognostic information. In multivariate analysis, ESR1 mRNA expression emerged as a prognostic factor, independent of stage, grade, residual tumor mass, age, and ERalpha protein expression (HR 0.227 (CI 0.078-0.656), P=0.006). Our results indicate that the determination of ESR1 levels by kinetic PCR may be superior to immunohistochemical methods in assessment of biologically relevant levels of ER expression in ovarian carcinoma, and is feasible in routinely used FFPE tissue.
