Multimodal Treatment of Primary Advanced Ovarian Cancer.

Epithelial ovarian cancer is the second most common malignancy of the female genital tract, with approximately 7,400 new cases annually in Germany. With 5,500 deaths per year, ovarian cancer is the leading gynecologic cause of death. Epithelial ovarian cancer is characterized by morphologic heterogeneity with 4 molecular biological subtypes (immunoreactive-like, differentiated-like, proliferative-like, mesenchymal-like) with different prognosis. Significantly improved survival is achieved by optimal debulking with no residual disease (R0). Systematic lymphonodectomy of clinical negative lymph nodes has no effect on overall survival in advanced ovarian cancer. Interval debulking in advanced ovarian cancer after three cycles of neoadjuvant chemotherapy with carboplatin/paclitaxel is controversial. Standard chemotherapy for advanced ovarian cancer consists of six cycles of carboplatin AUC5 and paclitaxel 175 mg/m ² , in a three-week cycle. Intraperitoneal chemotherapy is not a standard therapy. Anti-hormonal therapy with an aromatase inhibitor plays a minor role in therapy of both low grade serous ovarian cancer (LGSOC) and high grade serous ovarian cancer (HGSOC). A major achievement in ovarian cancer therapy has been the results of the SOLO-1 trial, in which olaparib as a first line maintenance monotherapy resulted in an overall 70% lower risk of disease progression in patients with advanced Breast Cancer Gene (BRCA)-mutated ovarian cancer.
