Platinum sensitivity is the most important prognostic factor in patients with ovarian cancer metastatic to the brain. This novel finding should be considered in the strategy of multimodal therapy for brain metastases in ovarian cancer.

Aim: To determine quality of life, effectiveness and safety of oral netupitant-palonosetron (NEPA)–based antiemetic prophylaxis in the real-world setting. Materials & methods: Prospective, noninterventional study in adults receiving highly or moderately emetogenic chemotherapy and NEPA for three cycles. NEPA was administered per summary of product characteristics. Results: A total of 2429 patients enrolled, 2173 were evaluable. ‘No impact on daily life’ due to vomiting was reported by 85%/82% of patients in the highly emetogenic chemotherapy/moderately emetogenic chemotherapy groups in cycle 1, with rates of 54%/59% for nausea. Overall, complete response rate was 89%/87%/75% in the acute/delayed/overall phases. NEPA was well tolerated. Conclusion: NEPA had beneficial effects on the quality of life of a heterogeneous group of cancer patients and was safe and effective in the real-world setting.

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 formalinfixed 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 ERa 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), PZ0.002). ERa protein expression was correlated to ESR1 mRNA expression (PZ0.0001); however, ERa 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 ERa protein expression (HR 0.227 (CI 0.078-0.656), PZ0.006). 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.
