| Summary: | Background:
B-cell lymphoma 2 (Bcl-2) is an antiapoptotic protein and an important clinical breast cancer prognostic marker. The aim of this study was to evaluate the relationship between the BCL2 expression and clinico-pathological parameters in breast cancer.
Materials and Methods:
Present study is observational cross-sectional study of 100 biopsy proven cases of breast cancer, and cases with resection specimens were included. IHC analyses for ER, PR, Her2neu, Ki67 and Bcl2 were performed in each case.
Results:
Bcl2 expression was seen in 52% cases. BCL2-positive expression was associated with lower histological grade (0.026), low Ki-67 level (<14%, P < 0.001), hormone receptor positivity (P < 0.001) and luminal breast cancer (P < 0.001) but no association with tumour size, lymphovascular invasion, perineural invasion and TNM stage.
Conclusion:
Expression of Bcl-2, an antiapoptotic protein, is associated with low-grade, slowly proliferating, luminal A-type BC. IHC analysis of Bcl-2 is simple, inexpensive, readily available test to stratify early-stage hormone-positive patients who can be included in clinical trials for Bcl-2 inhibitors. |
