Other related information <Study Design>
This is a Japanese, multi-center, observational study. Patients with newly diagnosed FIGO stage III - IV OC after 1st January, 2019 will be enrolled sequentially.
Patients those who have undergone or are planning to undergo BRACAnalysis, which detects BRCA mutations, are eligible for this study. In this study, data of 200 subjects will be collected at approximately 20 sites in Japan. To reduce regional bias of study sites, the number of enrolled patients per site will be capped.
The patient's clinical background information, sample collection information, etc. at enrollment will be collected and recorded from the medical records, etc.
Archived formalin-fixed paraffin-embedded (FFPE) samples from enrolled patients will be forwarded to the central laboratories for BRCA testing according to Sample Handling Procedures. Histopathology will be assessed by the central pathologists using serial sections of the submitted samples.

Summary of the rationale
Although gBRCAm testing was approved in Japan, tBRCAm had not been approved yet. Additionally, limited epidemiological data on the prevalence of tBRCAm in OC patients exists in Japan. Therefore, the objective of this study is to investigate BRCA mutations and homologous recombination deficiency (HRD) score in patients with newly diagnosed advanced (at the first diagnosis of) OC.
