Abstract
Research question
This study explored the knowledge, attitudes and practice of physicians towards fertility
and pregnancy-related issues in young BRCA-mutated breast cancer patients.
Design
Physicians attending two international breast cancer conferences completed a 26-item
questionnaire exploring fertility preservation, pregnancy during (BCP) or after breast
cancer. A statistical comparison was carried out of the responses exploring the same
issues in young breast cancer patients overall or specifically in those with BRCA mutations.
Results
The survey was completed by 273 physicians. Ovarian tissue cryopreservation (33% versus
40%; P = 0.009) and gonadotrophin-releasing hormone analogues during chemotherapy (74% versus
81%; P = 0.001) were less commonly suggested in BRCA-mutated patients than in the overall breast cancer population. 42% of respondents
agreed or were neutral on the statement that ovarian stimulation should not be considered
safe in BRCA-mutated breast cancer patients.
45% and 30% agreed or were neutral on the statement that pregnancy in breast cancer
survivors may increase the risk of recurrence in BRCA-mutated patients or in the overall breast cancer population, respectively (P < 0.001). 15% and 3% disagreed that transplanting the cryopreserved ovarian tissue
can be considered safe in BRCA-mutated patients or in the overall breast cancer population, respectively (P < 0.001). 33.3% were against the addition of platinum agents as neoadjuvant chemotherapy
in BRCA-mutated patients with BCP.
Conclusions
Several misconceptions on fertility preservation and pregnancy-related issues in breast
cancer patients persist even among physicians directly involved in breast cancer care.
Focused research efforts to address these issues in BRCA-mutated breast cancer patients and education to improve physicians’ knowledge and
adherence to available guidelines are urgently needed.
