Impact of pregnancy on non-metastatic breast cancer: a case control study.

ABSTRACT

The diagnosis of breast cancer during pregnancy remains uncommon and therefore leads to non-standardized management. We reviewed retrospectively 28 such women treated at this centre and compared them with age and stage matched controls. Differences in management and outcome were analysed for statistical significance. There was no significant difference in overall survival (P = 0.86) and relapse-free survival (P = 0.48) between the two groups. Chemotherapy after the first trimester of pregnancy carried no significant morbidity. Pregnancy does not appear to be an adverse prognostic factor for breast cancer.
