Bcl-2 and p53 gene products (Bcl-2, p53) are important regulators of apoptosis and cell proliferation, and their immunohistochemical expression may help to identify high-risk breast cancer patients. The authors evaluated p53 and Bcl-2 immunoreactivity in 178 node-negative breast cancers (NNBC) with long-term follow-up (median, 60 months). Bcl-2 was seen in 111 (62%) cases, and was significantly associated with small tumor size, nonductal morphology, low tumor grade, estrogen-receptor (ER) pos...Expand abstract
