ABSTRACT
Objective: To asses the frequency of HER-2/neu Oncoprotein over expression in invasive ductal breast cancer and correlate it various prognostic parameters.
Design:
Cross-sectional study.
Place: Department of pathology Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi.
Subjects & Methods: Seventy two (72) formalin fixed paraffin embed ded blocks of diagnosed invasive ductal carcinoma were retrieved and 5 p.m
Results:
179 aspirates were obtained from 158 patients. The cytological diagnosis were; 78 (43.6%) reactive, 43 (24.0%) tuberculous lymphadenitis, 27 (15.1%) suppurative inflammation, 15 (8.3%) non Hodgkin's lymphoma, 05 (2.8%) Hodgkin's lymphoma, 03 (1.7%) leukemic infiltration, 02 (1.1%) cytological diagnosis uncertain, 06 (3.4%) material inadequate. 06 cytological diagnosis were false negative and one was false positive. The overall accuracy was 96%.
