Abstract; Background: The expression of estrogen and progesterone receptors and human epidermal growth factor receptor-2 has been reported to have invaluable prognostic role. This study aimed at determining the expression ER, PR and HER2 in women with breast cancer in Kampala, Uganda.Methods: Expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) was determined immunohistochemically. Logistic regression was performed to determine the effect of the independent factors in predicting the risk of not expressing the breast markers. A two-tailed p<0.05 was regarded to be statistically significant.Results: ER, PR and HER2 were expressed in 53.4%, 46.6% and 18.5%, respectively. Co-expression of ER and PR and triple negative breast cancer was present in 42.7% and 37.9%, respectively. Age was an independent predictor of expression of ER (AOR = 0.18, 95% CI: 0.062-0.541, p = 0.002), PR (AOR = 0.35, 95% CI: 0.129-0.968, p = 0.043).Conclusion: Majority of patients in this study had less than 50 years and the majority of them had infiltrating ductal carcinoma of no special type with grade 2. Age predicted independently the expression of both ER and PR in our study. |
