Mantle cell lymphoma (MCL), an uncommon lymphoma subtype, is clinically characterized by its heterogenous behavior. Established prediction system including several clinical and biological parameters can help in determining the aggressiveness of MCL in younger patients. However, there are limited parameters on predicting the clinical outcome of older patients. The present study was performed to identify the prognostic factors and optimal treatment modalities in older Chinese MCL patients.Patients (age ≥ 65 yrs) with MCL from 19 comprehensive hospitals in China were included. Clinical characteristics, therapeutic strategies, progression-free survival (PFS) and overall survival (OS) time of these patients were collected.Totally, 259 eligible patients were enrolled. The median age of patients was 69 years (range, 65-88). The median of PFS and OS were 29 months (95%CI: 26-37) and 76 months (95%CI: 61-96) months, respectively. Multivariate regression analysis determined that ECOG score ≥ 2, high MIPI score and absence of maintenance treatment were independently associated with poorer PFS of MCL patients; while ECOG score ≥ 2 and absence of maintenance treatment were independently correlated with a poorer OS. Patients with MCL who received BTKi-containing regimens or maintenance therapy showed significantly longer PFS and OS than those who did not receive these therapies. Maintenance treatment can improve the survival rate of older patients with MCL regardless of TP53 status.ECOG ≥ 2, high MIPI score, and absence of maintenance therapy were associated with poorer survival outcomes for older Chinese MCL patients. Maintenance therapy and BTKi-containing regimens have been shown to increase the survival rate of older Chinese MCL patients.
