Background: Pregnancy-associated breast cancer (PABC) is breast cancer diagnosed during pregnancy or within 1 year of delivery. It is the most frequent malignancy diagnosed during pregnancy or lactation. There is a paucity of information on PABC in our hospital. Aim: The aim of the study is to highlight the clinicopathological features, treatment, and outcome of PABC in the center. Materials and Methods: It was a 6-year prospective study of PABC from January 2007 to December 2012 at our hospital. Information documented included patient's biodata, clinical features, pathological types, receptor status, staging, treatment, and outcome of PABC patients. Results: A total of 1344 patients had breast cancer during the study period. 31 patients (2.3%) had PABC. Age ranged 20–43 years, median 31 years. Common clinical features were: breast lump/mass – 27 (87.1%) patients, skin thickness – 10 (32.3%), nipple retraction – 9 (29.0%), and inflammation – 6 (19.4%). 19 (61.3%) patients were diagnosed in pregnancy: first trimester – 4 (12.9%), second trimester – 7 (22.6%), third trimester – 8 (25.8%), while 12 (38.7%) were within 1 year of delivery. Twenty-two patients (71.0%) had advanced disease. Twenty-four (77.4%) patients had invasive ductal carcinoma. Thirteen (59.1%) patients were ER/PR positive, 6 (27.3%) were triple negative, and 3 (13.6%) were HER2 positive. Twenty-four patients (77.4%) had vaginal delivery. Three patients (9.7%) had spontaneous abortion and 1 patient (3.2%) had still birth. 25 babies (80.6%) were alive and well. 17 patients (54.8%) had modified radical mastectomy (2 patients in second trimester and 15 patients after delivery), 25 (80.6%) had chemotherapy, 14 (45.2%) had radiotherapy, and 1 (3.2%) received trastuzumab. Mortality was 8 (25.8%). Conclusion: PABC constituted 2.3% of all breast cancer patients in our hospital. Majority (71%) presented with advanced disease. 3 out of every 4 were invasive ductal carcinoma, while 1 in 4 were triple negative. The mortality was 25.8%.
