[Effect of Modified LMB 89± Rituximab Regimen on Long-Term Benefits for Patients's with Burkitt Lymphoma]

To investigate the effect of modified LMB 89± rituximab regimen on long-term clinical benefit for patients with Burkitt lymphoma.

Clinical data of 43 patients with Burkitt lymphoma were collected and retrospectively analyzed in the period from July 2006 to October 2017. Forty-three patients were divided into 2 groups, including Hyper-CVAD regimen, R-EPOCD regimen or VDCLP regimen treated group as control (20 patients) and modified regimen group with modified LMB 89±rituximab regimen (23 patients); the event-free survival (EFS) rate, overall survival (OS) rate, cumulative incidence of relapse (CIR), non-relapse mortality rate (NRM) and adverse reaction incidence of 2 groups were compared. At the same time, the efficacy analysis for patients of modified regimen group was performed according to age and using rituximab or no.

The EFS rate and OS rate of modified regimen group were significantly higher than those of control group (P＜0.05). The CRR rate and NRM rate of modified regimen group were significantly lower than those of control group (P＜0.05). The EFS rate and OS rate of patients for ＜40 years old were significantly higher than those of patients for ≥40 years old in modified regimen group (P＜0.05). The EFS rate and OS rate of patients with rituximab were significantly higher than those of patients without rituximab in modified regimen group (P＜0.05). There was no significant difference in the adverse reaction incidence between 2 groups (P＞0.05).

Modified LMB 89± rituximab regimen in the treatment of patients with Burkitt lymphoma can efficiently prolong survival time and shows the better safety; and the remigen combined with rituximab is more helpful to improve the clinical prognosis and show the better clinical effects for the patients≤40 years old.
