Prostate cancer is one of the most common malignant tumors among males, and nearly all patients will inevitably de-velop castration-resistant prostate cancer (CRPC). The prognosis of CRPC patients is very poor. How to implement the individualized treatment plan with minimal side effects and optimum benefit as well as how to prolong the patients' lives have recently become impor-tant issues. Current staging and grading systems fail to provide accurate prognoses of most CRPC, which have complicated biological behaviors. Over the past few years, a host of tumor molecular markers have been discovered and can provide prognostic information for CRPC. This review summarizes the molecular prognostic biomarkers that affect the prognosis of CRPC.

Objective To investigate the expression and clinical significance of bcl-2 and NF-κB/ p65 in different subgroups of diffuse large B-cell lymphoma (DLBCL). Methods Immunohistochemical staining was used to detect the expressions of CD10, bcl-6, and MUM-1 in the DLBCL patients. According to immunohistochemical algorithm of Hans et al. DLBCL were subdivided into GCB and non-GCB/ABC subgroups and the expressions of bcl-2 and NF-κB/p65 were detected. The expressions of bcl-2 and NF-κB/ p65 in GCB DLBCL were compared with that in ABC DLBCL,and the correlation of bcl-2 and NF-κB/p65 expressions with survival in the two major subgroups of DLBCL were analyzed. Results The expression rates of bcl-2 and NF-κB/p65 proteins in DLBCL were 67.1% and 77.1%, and there was significant correlation between them. The expression rates of bcl-2 and NF-κB/p65 were 52.0 % and 56.0 % in GCB DLBCL, but were 75.6 % and 88.9 % in ABC DLBCL. The expression rates of two proteins were higher in ABC DLBCL than in GCB DLBCL. There was no significant correlation between bcl-2 and NF-κB/p65 protein expressions and overall survival within the GCB DLBCL subgroup, but bcl-2 and NF-κB/p65 expressions had a significant effect on overall survival within the ABC subgroup. Conclusion bcl-2 and NF-κB/p65 expressions are associated with poor survival in the ABC subgroup only. Hence, the significance of bcl-2 and NF-κB/p65 protein expressions should be assessed in the context of DLBCL subgroups in the future.
