Abstract

To report the expression of estrogen receptors, progesterone receptors and human epidermal growth factor receptor (Her-2/neu) in 158 Kenyan women with breast cancer and correlation with other prognostic indicators in this high-risk group. This study stressed the importance of routine assessment of the steroid receptors and Her-2/neu as a mode of therapeutic selection of patients for antihormonal or targeting monoclonal antibody (Herceptin) therapy, directed at the juxtamembrane domain of Her-2/neu protein in the developing countries such as Kenya. The study population consisted of 158 female patients with histologically confirmed breast carcinoma seen at the pathology department of The Nairobi Hospital. An immunohistochemical (IHC) study of ER, PR and Her-2/neu was conducted, followed by fluorescent in situ hybridization (FISH) validation for Her-2/neu gene amplification in cases initially scored as positive 2+ with IHC. Mastectomy samples registered at the pathology department of The Nairobi Hospital were used for this study. The study was approved by the institution's ethical review committee and informed consent obtainedfrom the concerned patients. In the studied cohort, positivity for both hormonal receptors and Her-2/neu w...Continue Reading

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
