OVArian Cancer Non-Interventional Study - OVATAR

This is a multicentre, non-interventional, prospective study to be carried out in representative hospitals in order to assess ovarian, fallopian tube and peritoneal cancer management in Russia. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. Treatment assignment will be done according to the current practice. It is planned to enrol 300 subjects in up to 30 sites in Russian Federation. The average number of patients per site is planned as 10-15; there are no restrictions on minimum and maximum number of subjects per site in this study. The disease treatments approaches in 1st line treatment of serous and endometrioid ovarian, peritoneal and fallopian tube cancer (both chemotherapy and surgery) is considered as the primary outcome variable in this study. Along with other diagnosis examinations the analysis of frequent mutations in the gen BRCA1 (5382insC, 4154delA, 185delAG and C61G (c.300T\>G)) will be performed by local or regional laboratories. Those patients with BRCAm+ OC (Ovarian Cancer) will be observed prospectively during 2 years after the baseline visit or till progression at the 1st line treatment with regards to OC treatment details and outcomes. The patients for whom BRCA mutations not found will participate in the baseline assessments only and will not be followed up. Accordingly, 1 study visit (screening/baseline) is planned for all patients and 1 FU visit (Year 2) is planned for BRCAm+ patients. The subpopulation of the patients with the congenital serous and endometrioid ovarian, peritoneal and fallopian tube cancer with the corresponding family history will undergo the broadened genetic testing panel (sequencing of all coding areas of genes BRCA1 and BRCA2). Information regarding patient demographics, the disease characteristics, management approaches, diagnostic tests performed and medication received by the patient will be taken from the medical records.
