Abstract

The aim of this study is to systematically evaluate the safety and efficacy of rituximab plus CHOP (R-CHOP combined regimen) in patients with previously untreated diffuse large B cell lymphoma (DLBCL). Electronic database were searched for randomized-controlled studies only comparing R-CHOP to CHOP standard alone in patients with untreated DLBCL were included. The risk ratios (RRs) with their 95% corresponding intervals (95% CI) were employed to estimate the efficacy of overall response (OR), complete response (CR), risk of dying and relapse rate in followed-up period. Total ten case-control studies containing 2941 patients met the inclusion criteria. The addition of R to standard CHOP were showed to increase the proportion of CR (RR=1.23, 95% CI=1.13-1.35, P<0.00001) and OR (RR=1.39, 95% CI=1.24-1.55, P<0.00001) in a fixed-effect model, indicating that rituximab combined with CHOP regimen is efficacy than CHOP alone. It did not increase the overall risk of dying as a consequence of infection (RR=0.79, 95% CI=0.55-1.13, P=0.20). Furthermore, the relapse rates is significantly lower in R-CHOP (RR=0.52, 95% CI=0.38-0.71, P<0.0001). The adverse effects were also not significant (P>0.05). In summary, R-CHOP regimen is superior to s...Continue Reading
