FLABRA: Frontline approach for BRCA testing in OC treatment naïve population. A LATIN AMERICA Epidemiologic Study - FLABRA

This study aims to answer very important questions regarding the prevalence of somatic and germline mutations (sBRCAm and gBRCAm) in a population of newly diagnosed ovarian cancer patients from Latin America. These answers may be extremely helpful in the counseling for genetic risk and treatment approach in these populations and will aid in making treatment decisions in the future

FLABRA is a cross-sectional, multi-center, epidemiological observational study designed to evaluate the prevalence of BRCA mutations in newly diagnosed ovarian cancer patients across understudied ethnic groups in Latin America. Secondary objectives of the study are to evaluate the prevalence of sBRCAm versus gBRCAm in newly diagnosed ovarian cancer patients and to describe current ovarian cancer counselling and treatment approach patterns at front line setting across Latin America. In the Screening Visit, consecutive eligible patients who have been newly diagnosed with ovarian cancer within the last 120 days will be invited to participate. After having provided consent, patients will be asked to provide ethnicity and cancer family history information. Patients will self-identify to one or more of the defined broad ethnic groups (Native American, Afro-Caribbean, Caucasian) based on self-reported ancestry information. Archived tumor blocks or twenty 10-µm sections from eligible patients will be requested from the local pathology lab and used for BRCA mutations testing. Patient medical records will be reviewed for data relevant to the ovarian cancer diagnosis, including basic demographics, medical history, and treatment history. During the Devolution Visit, results of the tumor BRCA test will be communicated to the patient, and information about counselling approach and treatment plan will be recorded in the medical chart. This Devolution Visit will be the last visit for this study for the cases of non-mutated patients. For patients for whom a BRCA mutation have been identified in tumor, additional test in blood looking for the specific point mutation found in tumor will be performed to investigate if these patients harbor a germline BRCA mutation. For these patients a further visit will be organised to communicate results to the patient and data regarding germline test results will be recorded in the medical chart of the patient.
