Profile of Triple Negative Breast Cancer: A Retrospective Review.

Background: Triple-Negative Breast Cancer (TNBC) is a particularly aggressive tumor. Major responses to chemotherapy in TNBC do not necessarily correlate with better survival, indicating a need for further research into treatment strategies and underlying molecular mechanisms. This study is aimed at assessing the profile of Triple Negative Breast Cancer. Methodology: This study retrospectively evaluated the profile of TNBC patients at Lagos State University Teaching Hospital, Ikeja. Sociodemographic data, tumour grade, and type of chemotherapy administered were abstracted from the hospital's cancer register. Statistical analyses were conducted using SPSS version 27.0, with associations between sociodemographic characteristics, tumour grade, and type of therapy established using chi-square tests. Key relationships were considered statistically significant at p-values ≤ 0.05. Result: A total of three hundred and thirty (330) patients were recruited. The mean age of presentation was 49.96 ± 11.39 years, with the minimum and maximum ages of 22 and 80 years, respectively. The most represented age group was between 41-50 years, constituting about a third of all the patients. About three quarters of the tumours were moderately differentiated. Correlating tumour grade with the age of the patients was statistically significant, p value =0.05. Conclusions: Triple-negative breast Cancers remain a moderately differentiated tumour and are seen predominantly in the middle-aged group.
