ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship of clinopathological features and outcome of rituximab treatment for diffuse large B-cell lymphoma (DLBCL).</p><p><b>METHODS</b>Sixty-nine patients with DLBCL received intravenous infusion of rituximab in combination with different chemotherapy regimens have been retrospectively analyzed. The influencing factors such as age, stage, serum level of lactate dehydrogenase (LDH) and bulky disease were analyzed retrospectively in terms of the response. The anti-/ pro-apoptosis proteins were detected by immunohistochemistry (SP methods). The correlation of protein expression with efficacy of rituximab treatment was also analyzed.</p><p><b>RESULTS</b>In the patients with previously untreated aggressive B-NHL, the combination of rituximab with chemotherapy achieved an overall response rate (ORR) of 90.7% and CR of 69.8%, while in the patients with relapsed disease, that was 80.8% (ORR) and 30.8% (CR). The disease stage (P = 0.046), serum lactate dehydrogenase (LDH) (P = 0.024), physical status (P = 0.009) and bulky disease (P = 0.013) were found to be unfavorable factors for the immunochemotherapy. The treatment efficacy in the patients with Bcl-2 overexpression was better than that in cases with negative one. No correlation of the bax and survivin expression with immunochemotherapy efficacy was observed.</p><p><b>CONCLUSION</b>The immunochemotherapy regimen (rituximab plus chemotherapy) can improve the response rate and CR rate without significant increase in toxicity in patients with diffuse large B-cell lymphoma. The advanced stage, high serum LDH level, relapsed disease, bulky disease and negative Bcl-2 expression are unfavorable factors affecting the therapeutic efficacy.</p>
