Abstract
To investigate the clinical efficacy of R-EDOCH protocol in the treatment of newly diagnosed double expression lymphoma. The clinical data of 51 patients with newly diagnosed double expression lymphoma treated by R-EDOCH protocol were retrospectively analyzed in the period from May 2012 to October 2017, then overall remission rate (ORR), disease control rate (DCR), progression-free survival (PFS) rate and total survival (OS) rate were evaluated; moreover the patients were grouped according to IPI score and whether accepting hematopoietic stem cell transplantation(HSCT) and the clinical efficacy was compared. The ORR was 96.08% (49/51) and DCR was 100.00% (51/51) in all patients. Six cases out of 51 patients (11.76%) relapsed and progressed during the followed-up. The followed-up showed that 2 year-PFS rate and OS rate were 84.31% (43/51) and 94.12% (48/51) respectively. The ORR, SD rate, 2 year-PFS rate and OS rate in the patients with IPI 0-2 and 3-5 scores were no statistically different(p>0.05); the 2 year-PFS and OS rates between patients in subgroup of IPI 0-2 and 3-5 scores also were not statistically different (p>0.05), no matter whether the patients received auto-HSCT or not. The comparison of 2 year-PFS and OS rates in auto-HSCT patients and non-auto-HSCT patients showed no statistical difference(p>0.05). The R-EDOCH protocol in treatment of newly diagnosed double expression lymphoma possess the good overall clinical efficacy, the combination of R-EDOCH with auto-HSCT displays ascending trend of PFS.
