Pregnancy Outcome and Safety of Interrupting Therapy for Women With Endocrine Responsive Breast Cancer

The best available evidence suggests that pregnancy after breast cancer does not increase a
woman's risk of developing a recurrence from her breast cancer. In particular, the most
recent data suggest that this is the case also in women with a hormone receptor-positive
breast cancer. There is also no indication of increased risk for delivery complications or
for the newborn. The aim of the study is to investigate if temporary interruption of
endocrine therapy, with the goal to permit pregnancy, is associated with a higher risk of
breast cancer recurrence.The study aims also to evaluate different specific indicators
related to fertility, pregnancy and breast cancer biology in young women. A
psycho-oncological companion study on fertility concerns, psychological well-being and
decisional conflicts will be conducted in interested Centers.
