Summary
Bcl-2 expression in prostate cancer predicts worse outcomes. Patients with Bcl-2 negative tumors had longer biochemical recurrence-free survival, indicating Bcl-2
Area of Science:
- Oncology
- Molecular Biology
- Pathology
Background:
- Prostate cancer is a significant health concern.
- Identifying predictive factors for biochemical recurrence (BCR) after radical prostatectomy (RP) is crucial for patient management.
Purpose of the Study:
- To investigate Bcl-2 expression in localized prostate cancer.
- To evaluate Bcl-2 as a predictive factor for BCR following RP.
Main Methods:
- Retrospective analysis of 171 Korean patients undergoing RP.
- Immunohistochemical assessment of Bcl-2 expression in RP specimens using tissue microarray.
- Statistical analysis including Cox proportional hazard models.
Main Results:
- Bcl-2 expression was detected in 24.6% of patients.
- Bcl-2 negative patients showed significantly longer BCR-free survival.
- Univariate and multivariate analyses identified Bcl-2 expression as a significant predictor of BCR, alongside PSA, SVI, and positive surgical margin.
Conclusions:
- Bcl-2 expression in RP specimens is associated with poorer patient outcomes.
- Post-operative Bcl-2 expression may serve as a valuable predictor of BCR after RP.
