c-erbB-2 ONCOPROTEIN OVER-EXPRESSION IN BREAST CANCER AND ITS RELATIONSHIP TO HISTOLOGY AND GRADE IN A UGANDAN POPULATION
Abstract
Objective: To evaluate c-erbB-2 oncoprotein over expression in breast cancer patients of Kyadondo county and also relate this oncoprotein to histological type and grade of the tumour.
Design: Cross-sectional study.
Setting: Pathology Department, Faculty of Medicine, Makerere University.
Subjects: Seventy two breast cancer patients who were among the 174 entered in survival study had their paraffin breast tissue blocks retrieved from archives of Pathology Department and had their c-erbB-2 determined by peroxidase-labeled streptavidin-biotin immunohistochemical method.
Results: c-erbB-2 oncoprotein was over expressed in 33.3% of the tumours and correlated positively with histological grade (p = 0.007). TH oncoprotein over expression was not restricted to any particular histological type and there was no association with age of patient.
Conclusion: The over expression of c-erbB-2 oncoprotein observed in one third of breast cancer patients of this African population could partly explain the observed poor survival rate reported in this community.
