Key clinical point: The combination of the prognostic mantle cell lymphoma (MCL) International Prognostic Index (MIPI) with biological risk factors Ki-67 and p53 expression identifies a subset of patients with MCL having poor prognosis.
Major finding: Patients with high combined MIPI (MIPI-c) or p53 expression > 50% (high-risk disease) vs low, low-intermediate, or high-intermediate MIPI-c and p53 expression ≤ 50% (low-risk disease) had significantly shorter median failure-free survival (hazard ratio [HR] 2.97) and overall survival (HR 3.69) at median follow-ups of 9.6 and 9.4 years, respectively (both P < .0001). The results were confirmed in validation cohorts.
Study details: The training cohort included 684 patients with MCL from the MCL-Younger and MCL-Elderly trials with evaluable data for Ki-67 or p53; patients were classified as having high-risk or low-risk disease. The validation cohorts included 230 and 44 patients from the MCL0208 and Nordic-MCL4 trials, respectively.
Disclosures: This study did not receive any funding. Some authors declared serving on advisory boards or speakers’ bureaus of or receiving research funding, consultancy fees, or honoraria from various sources.
