Abstract:
Objective:To investigate the effect and prognostic factors of rituximab-containing chemotherapy regimen in treatment of patients with mantle cell lymphoma (MCL).Methods:The clinical data of 56 patients aged ≤65 years in the First Affiliated Hospital of Soochow University from June 2007 to November 2018 were retrospectively analyzed. Rituximab-containing chemotherapy regimen was used, and the effects of clinical features, treatment regimen and biological indexes on overall survival (OS) and progression-free survival (PFS) were observed.Results:The median age of 56 patients was 57 years old, including 43 males and 13 females. Among these cases, 24 patients received R-CHOP chemotherapy regimen; 29 patients received cytarabine-containing chemotherapy regimen, including R-hyper CVAD/R-MA regimen used in 15 patients and R-CHOP alternating with R-DAHP regimen used in 14 patients; and 3 patients received other treatment regimens. Among 56 patients, 19 patients received autologous hematopoietic stem cell transplantation (ASCT) consolidation therapy. The median OS time was 74 months, 2-year OS rate was 83.8%, 3-year OS rate was 70.9%, 2-year PFS rate was 72.0% and 3-year PFS rate was 49.7%. International prognostic index (IPI) high-risk and receiving ASCT or not during the treatment were independent influencing factors of OS and PFS in MCL patients. The overall response rate (ORR) in cytarabine-containing regimen group was higher compared with that in R-CHOP regimen group (93.1% vs. 83.3%), and there was no statistically significant difference ( χ2=0.465, P=0.495). In addition, there were no significant differences between two groups in both OS ( χ2=0.291, P=0.590) and PFS ( χ2=0.912, P=0.339). ASCT consolidation prolonged the median OS time (72 months vs.124 months, χ2=3.973, P=0.040) and the median PFS time (34 months vs. 90 months, χ2=3.984, P=0.046) in MCL patients achieving remission after induction therapy. Among patients in simplified MCL IPI (sMIPI) score middle-high risk group, compared with those not receiving ASCT, patients receiving ASCT therapy could obtain better OS and PFS (OS: χ2=5.037, P=0.025; PFS: χ2=6.787, P=0.009); among patients of sMIPI score low risk, there were no statistically significant differences in OS and PFS between the group receiving ASCT and not (all P > 0.05). Conclusions:Cytarabine-containing chemotherapy regimen has no predicatively satisfactory value in improving the prognosis and survival for MCL patients. For MCL patients who have achieved remission after reduction therapy and those in sMIPI score middle-high risk group, ASCT consolidation therapy can improve the prognosis and can be taken as the first-line consolidation treatment in young patients.
