Abstract

Background: Breast cancer is the commonest cancer in the female. Immunohistochemistry of breast cancer hormone receptor (ER and PR) and Her2 are very useful tools for assessing the tumor cells behavior and making choice of chemotherapy.

Aims and Objective: The study aimed to describe the immunohistochemical profiles of breast carcinoma at University of Calabar Teaching Hospital (UCTH), Calabar.

Method: This is a descriptive study of immunohistochemistry of breast carcinoma in UCTH using archival paraffin-embedded blocks of breast cancer tissue. The records of cases diagnosed as breast cancer in a five year period (2010-2014) in the department of Histopathology of UCTH are stained immunohistochemically for Oestrogen receptor(ER), Progesterone receptor(PR) and Human epidermal growth factor receptor 2(Her2). The demographic variables and receptor status were collated and analyzed. The status is related to the histopathologic characteristics of tumor size, histologic grade, and histologic subtypes. The findings were presented in tables and charts and statistical significance of variables tested.

Result: One hundred and forty-seven (147) cases of breast cancer samples were analyzed. The mean age at diagnosis was 46.31+/-12.75 years old. The age ranged from 21-80 years old, the modal and median ages were 40 and 45 years respectively. Sixty-four percent (64%) were estrogen receptor positive. Progesterone receptor positive was 40.14% and Her2 positive was 21.09%.

Conclusion: The majority of the breast cancer is estrogen receptor positive but progesterone receptor and Her2 receptor negative.
