Receptor Status and Associated Clinico- Histopathological Characteristics among Women with Breast Cancer in a Ugandan Tertiary Hospital
Background: The breast cancer landscape in Uganda is characterized by late disease and poor outcomes. Even though receptor status is an important prognostic factor, it is not routinely conducted in the country. This study was set to describe the oestrogen receptors (ER) status and associated clinico-histopathological features of breast cancer among women in Uganda.
Method: A cross sectional descriptive study, carried out among women with histologically confirmed breast cancer, recruited at the Mulago Hospital breast clinic and determined their receptor status determined by immunohistochemistry (IHC), which was preceded by H&E staining.
Results: In total 114 women were enrolled over a 5 months period. Mean age was 47 years (13-87), half (50%) of the women had advanced disease (T4 tumours), 48/114 (42%) presented more than 12 months after onset of symptoms and most had poorly differentiated (grade III) invasive ductal carcinomas, 61/114 (53%) and 50/114 (44%) were ER- negative tumours.
Conclusion: Breast cancer is common among young African premenopausal women, it presents mostly as T4 tumours and close to half are ER negative. This is an over representation of ER negative tumours.
