Abstract
Background: Breast carcinoma is the most common malignant tumor and also one of the leading cause of the carcinoma deaths in women. There are many prognostic factors established for breast carcinoma. The most important prognostic factors of breast cancer are tumor size, histological grade and lymph nodal stage.
Objectives: To study the relative frequency, distribution and histomorphological features of breast carcinoma in the study group.
Materials and Methods: A total of 165 breast carcinoma specimens (Mastectomy) were enrolled between the period of September 2014 to August 2016. Age, tumor size, tumor grade, necrosis, associated breast lesions, lymph node involvement, lymphovascular invasion, lymphocytic response, skin infiltration, margin status were analyzed.
Results: Median age of the study group was 49 years. Invasive Carcinoma - Not Otherwise Specified was the commonest type, 38 cases (23%) had tumor less than 2 cm, 99 cases (60%) were of 2 to 5 cm in size and 28 cases (17 %) were more than 5 cm in size, 56.4% were grade 2 tumors. Node positive cases were 58.25 % (n=96), Skin infiltration was seen in 6.1% (n= 10), necrosis was seen in 47.3% (n=78), Lymphovascular invasion was seen in 74.5% (n=123), Positive margins were noted in 7.9% (n=13). Lymphocytic infiltration response was seen in 74.5% (n= 123).
Conclusion: Invasive carcinoma was the most common type. Incidence was more common at younger age group as compared to western population. More than half of the patients presented with lesser tumor size, lymph nodal metastasis, lesser grade and more lymphocytic response. This study population had better prognostic factors.
