[The Clinical-Biological Features and Prognosis of Patients with Mantle Cell Lymphoma]

To analyze the clinical-biological features and outcomes of patients with mantle cell lymphoma (MCL).

The clinical and laboratory data of 104 patients with newly diagnosed MCL who were admitted to the Department of Hematology, Fujian Medical University Union Hospital from January 2011 to December 2019 were retrospectively analyzed, and the efficacy was observed through survival analysis.

Among 104 MCL patients, 88 were male and 16 were female. The median age was 54 (25-79) years old, 93.0% (93/100) of the patients with advanced stage (III and IV stages) and 48.08% (50/104) of the patients with bone marrow infiltration. Patients with Ki-67≥50% had higher WBC counts and LDH levels. Univariate analysis showed that the patients with WBC≥15×10⁹/L, bone marrow involvement, high LDH, high β₂-MG levels, Ki-67≥50%, SOX11^-, had lower OS and EFS rates (P =0.005, 0.049, 0.033, 0.025, 0.042, 0.018 and 0.001, 0.021, 0.024, 0.035, 0.014, 0.026). The OS rate and EFS rate of patients in R-CHOP and R-Hyper-CVAD treatment groups were significantly higher than those in other treatment groups (P =0.02, 0.002 and P =0.001, 0.001). Patients with autologous stem cell transplantation (ASCT) had higher OS rate and EFS rate (P =0.037, 0.013). Multivariate COX analysis showed that only WBC count, SOX11 expression and whether achieved CR after 4 courses treatment were the independent factors affecting the prognosis.

MCL mainly occur in elderly men. There are many factors affecting patients' survival, while WBC≥15×10⁹/L, negative expression of SOX11 and failure to achieve CR after 4 courses of treatment are adverse factors for MCL patients.
