title: Triple negative breast cancer - our experience and review.
abstract: Triple negative breast cancer (TNBC) constitutes 10-25% of patients with breast cancer. TNBC is an aggressive phenotype affecting younger age groups and has poor prognosis. We retrospectively analysed 50 triple negative breast cancer patients attending our outpatient department among 270 breast cancer patients. The incidence of TNBC was 18.5%, and most of them were premenopausal 56% (28/50) with mean age was 46.66 ± 13.87 (Range 28-72 years). Most of them had Invasive ductal cancer 94% (47/50) and were high grade (Grade 3-96%)(48/50). Five patients presented with metastatic disease (2 patients only Skeletal, 1 patient with Skeletal and Lung, 1 patient with Lung and 1 patient with Liver) and 7 patients developed recurrence (all 7 had chest wall recurrence, 3 had supraclavicular lymph node recurrence, 2 had skeletal metastases and 1 had developed brain metastases) during follow up. The mean disease free survival was 15 months (Range 3-58 months) and overall survival was 20.14 months (Range 5-70 months). Fifty six percent (28/50) of patients were premenopausal and mean age of presentation was 46.66 ± 13.87 years (Range 28-72 years). Ten percent (5/50) presented with metastatic disease and 15% (7/45) developed metastases during follow up. Five patients (10%) died during follow up. Hence, Triple negative breast cancer is aggressive, with rapid progression leading to mortality in younger patients.
