Introduction: Breast cancer is the most common female cancer in the world. Triple negative breast cancer (TNBC) is a recently identified biological variant with aggressive tumor behavior and poor prognosis. Data of hormonal status from the Indian population is scarce due to financial constraints in performing immunohistochemistry evaluation. The present study aims to prospectively analyze receptor status of all breast cancer patients and identify TNBC and compare their clinical profile and short term survival with other non-TNBC group.
Materials and methods: All cytologically and histopathologically confirmed cases of carcinoma breast were prospectively enrolled. In a longitudinal study at tertiary care hospital in central India based on the hormonal status, they were further divided into TNBC and other groups. Comparison of risk factors, clinical profile and short-term survival was carried out.
Results: A total 85 patients were enrolled and of them 37 (43.7%) were TNBC. On comparing risk factors ie, age, age at menarche, total reproductive age, age at first child birth, and menopausal status – no statistical significance was observed between the TNBC and non-TNBC groups. But on comparison of clinical profile TNBC tumors were significantly large with majority of patients presenting as locally advanced breast cancer (83%). No statistical difference was observed in axillary lymph node status between two groups. TNBC tumors were histologically more aggressive (grade 3) compared to other groups. No statistically significant difference was observed in short term overall survival but all three deaths were observed in the TNBC group only and two local recurrences after surgery were observed in the TNBC group.
Conclusion: TNBC forms a large proportion of carcinoma breast patients in a central Indian scenario and needs more research to identify appropriate treatment planning considering aggressive histology and advanced presentation.
