In the univariate model, mutations of TP53 (11%) and NOTCH1 (4%), and deletions of TP53 (16%) andCDKN2A(20%),weresignificantly associatedwithinferioroutcomes(togetherwithMIPI, MIPI-c, blastoidmorphology, and Ki67 > 30%); however, inmultivariate analyses, only TP53 mutations (HR, 6.2; P <.0001) retained prognostic impact for overall survival (OS), whereas TP53 mutations (HR, 6.9; P <.0001) andMIPI-c high-risk (HR, 2.6; P5.003) had independent prognostic impact on time to relapse. TP53-mutated cases had a dismal outcome, with a median OS of 1.8 years, and 50% relapsed at 1.0 years, compared to a median OS of 12.7 years for TP53-unmutated cases (P <.0001). TP53 mutations were significantly associated with Ki67 > 30%, blastoid morphology, MIPI high-risk, and inferior responses to both induction- and high-dose chemotherapy. In conclusion, we show that TP53mutations identify a phenotypically distinct and highly aggressive form of MCL with poor or no response to regimens including cytarabine, rituximab, and autologous stem-cell transplant (ASCT). We suggest patients with MCL should be stratified according to TP53 status, and that patients with TP53 mutations should be considered for experimental frontline trials exploring novel agents.",
