ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy, safety and prognostic impact of rituximab plus CHOP (R-CHOP) regimen on patients with diffuse large B-cell lymphoma (DLBCL), to access the impact of R-CHOP on patients' prognosis and to compare that with CHOP regimen.</p><p><b>METHODS</b>Five hundred and seven newly diagnosed DLBCL patients were enrolled from Jan. 1, 2000 to May 1, 2010. Patients were administered with 6 cycles of CHOP or at least 4 cycles of R-CHOP treatments. Rituximab was administered intravenously on day 1 at a dose of 375 mg/m(2). The typical CHOP regimen include cyclophosphamide (750 mg/m(2), IV), doxorubicin (50 mg/m(2), IV) and vincristine (1.4 mg/m(2), IV, maximum 2 mg) and prednisone (60 - 100 mg, oral, day 3 - 7). The complete response (CR) rates, overall response (OR) rates, and side events of these 2 groups were compared.</p><p><b>RESULTS</b>Of the 411 analyzable patients, 224 received CHOP regimen and 187 received R-CHOP regimen. CR rate for R-CHOP group and CHOP group was 77.01% and 71.43%, respectively. OR rate in R-CHOP group was higher than that in the CHOP group (95.19% vs 87.95%, P = 0.007). The median follow-up time of R-CHOP group was 28.1 months vs that of 35.2 months in CHOP group. There was significant difference in progression free survival (PFS) and overall survival (OS) between 2 groups (P = 0.018 and 0.034, respectively). At the end of follow-up, the estimated median PFS in R-CHOP group had not been reached, while that was 84.8 months in CHOP group. The median OS in both groups had not yet been reached. The adverse events in R-CHOP group were similar with that in CHOP group.</p><p><b>CONCLUSIONS</b>R-CHOP is a safe and effective regimen for management of newly diagnosed DLBCL, with a better remission rate, PFS and OS.</p>
