ABSTRACT
Background and Objectives: - Carcinoma Breast is most common malignancy in females in USA and second among cases deaths in females (after lung cancer). There is considerable geographic , ethnic and racial variability in Breast cancer in evidence with about 5 fold variation throughout the world. Triple negative breast cancer is a heterogonous disease diagnosed by Immune Histo Chemistry (IHC).Triple Negative Breast cancer is characterized by tumor that do not express ER or PR and HER2neu . Proto typical Triple Negative Brest cancer is aggressive in nature and associate with poor prognosis. The Objectives of this study is to analyse the clinical and Pathological features of Triple Negative Breast Cancer and compare the result with similar studies in literature. Fifty Methods:- cases Triple negative Breast Cancer were included in this study. Clinical and pathological features and treatment were noted. Incidence Result:- of Triple Negative Breast Cancer was 35%. The median age of presentation was 45yrs. There were 4% males Triple negative Breast cancer cases out of female patients, most of patients were Pre (or) Perimenopausal(65%). 4% patients had family history of malignantly. Most common stage of presentation was stage III (46%). In Stage IV, Lung and bone metastasis was common. Ten Patients received Neoadjuvant chemo therapy (NACJ) and disease progressed in 4% while on Neoadjuvant chemotherapy, Even though 45 patients had surgery only 34 were eligible to received Adjuvant Radiotherapy. Total of 18% Patients had either progressive disease while on treatment (8%) (or) recurrence 10%. Eighteen percent patients died due to the disease. 33% patients on follow up. There were more Invasive Duct Cell carcinoma (IDCC) cases with medullary differentiations (or) Purse medullary Carcinomas (12%). No deaths Occur in the medullary variants TNBC. Majority of the tumor were high grade margins were negative in most of the cases. Incidence of Tri Inclusion:- ple negative breast cases was higher than western literature but comparable to Indian Studies. The age of Presentation was about 10 years younger than western data. Triple Negative Breast cancer was more common in young, pre (or) perimenopausal women. Small number of patients had family history, majority were state II (or) III. There was high number of progressive disease, recurrence and death while on the study (or) within less than 1 yr of treatment. Triple Negative Breast cancer is very aggressive disease with relatively better prognosis in the medullary variant Triple Negative Breast Cancer.
