Although the survival rate of diffuse large B cell lymphoma (DLBCL) has increased with years, there are still patients who do not achieve complete remission or who relapse, especially patients with activated B cell-like (ABC) DLBCL. Bortezomib, a proteasome inhibitor, has shown activity in diffuse large B cell lymphoma, especially in the subtype of ABC DLBCL. We conducted a meta-analysis to compare the efficacy and adverse events in bortezomib-containing regimens with standard R-CHOP regimen in treating DLBCL. Our results show that comparing to standard R-CHOP regimen, bortezomib-containing regimen could not prolong the survival in patients with ABC DLBCL. And patients who received bortezomib had a trend of higher risk with peripheral neuropathy, although there is no significant statistical difference.
