Because of lacking of head-to-head comparison among recently effective novel agents' combination regimens for newly diagnosed patients with mantle-cell lymphoma (MCL) who are ineligible for intensive therapy like autologous stem-cell transplantation, the optimal option for these patients still remains undefined. We searched relevant published reports. Three randomized controlled trials with 1459 subjects were identified. In the network meta-analysis, ibrutinib plus bendamustine and rituximab (Ibru + BR) significantly improved progression-free survival (PFS) when compared to bortezomib, rituximab, cyclophosphamide, doxorubicin, and prednisone (VR-CAP; hazard ratio [HR]: 0.55, p = .03) and rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; HR: 0.35, p < .001) for newly diagnosed patients with MCL ineligible for intensive therapy. Among these first-line treatment regimens (Ibru + BR, VR-CAP, R-CHOP, and BR), Ibru + BR had the highest probability of 94.9% to be the best intervention in PFS analysis. No significant difference was found in adverse events analysis. Our data indicated that Ibru + BR seemed to prolong the PFS when compared to VR-CAP and R-CHOP for newly diagnosed patients with MCL ineligible for intensive therapy. Considering our limits, prospective clinical trials directly comparing these regimens are warranted.
