Abstrakt:	Genetic testing has become increasingly used in medical practice to enable genetic cancer risk assessment. In Hereditary Breast and Ovarian Cancer syndrome (HBOC), it can be used to screen pathogenic germline variants. The access to early diagnosis, from the request until the proper interpretation of genetic tests depends on medical knowledge. The aim of this study was to evaluate the knowledge of family physicians, oncologists, geneticists and gynecologists regarding genetic testing for patients with suspected HBOC in Brazil. A cross-sectional survey of physicians was performed using a self-administered questionnaire. One hundred and ninety-two physicians answered the questionnaire (23 were geneticists, 38 gynecologists, 39 family physicians, and 92 oncologists). Only 15.4% of family physicians and 26% of gynecologists feel prepared to order genetic testing for patients with personal and/or family history of breast and/or ovarian cancer. Even though 87% of the oncologists have genetic testing available in their clinical practice, only 51.1% consider they have sufficient knowledge to manage patients after detecting a pathogenic germline variant and 17.4% do not feel comfortable interpreting them. Most oncologists and geneticists are very knowledgeable about recommendations for genetic testing order and management of HBOC patients. On the other hand, gynecologists and family physicians order genetic testing less frequently (28.9% and 7.7%, respectively) and have difficulties interpreting (26.3% and 2.3%, respectively) and managing these patients. These observations raise important issues regarding the implementation of genetic testing in Brazil, including the development of training programs for physicians from different specialties.
