Abstract:
Objective:To investigate the clinical features, survival and prognostic factors of elder patients with diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of elder patients with diffuse large B-cell lymphoma enrolled in the Cancer Hospital of Chinese Academy of Medical Sciences from April 2006 to December 2012 were retrospectively collected. All the patients were divided into R-CHOP-like group and CHOP-like group according to the dosage regimen. And the differences in demographic characteristics, clinical features, survival time and prognostic factors were compared between these two groups.Results:A total of 158 patients were enrolled, of which 78 patients in the R-CHOP-like group and 80 patients in the CHOP-like group were eligible. There were no significant differences between two groups on age, gender, pathological staging, B symptoms, bulky mass, ECOG score, IPI score, pathological type, LDH level, β 2-MG level, lymphocyte/monocyte ratio(LMR), neutrophils/lymphocyte ratio(NLR), platelet/lymphocyte ratio(PLR), Ki-67 index and bone marrow invasion. In the R-CHOP like group, the median progression-free survival (PFS) time was 10 months, and the median overall survival (OS) time was 30 months. The 1-year and 2-year PFS rates were 46.2% and 19.2%, respectively. The 1-, 2-, and 5-year OS rates were 79.5%, 59.0%, and 19.2%, respectively. In the CHOP-like group, the median PFS was 7 months, and the median OS was 15 months. The 1-year and 2-year PFS rates were 27.5% and 12.5% respectively. The 1-year, 2-year, and 5-year OS rates were 65.0%, 32.5% and 13.8%, respectively. The median PFS time and OS time in the R-CHOP group were significantly better than those in the CHOP group ( P<0.05 for both). A stratified analysis showed that the PFS time and OS time were superior in the R-CHOP-like group compared to the CHOP-like group among patients older than 70 years ( P<0.05 for both). In patients with stage Ⅲ-Ⅳ, the PFS time and OS time in the R-CHOP-like group were also superior to CHOP-like group ( P<0.05 for both). Univariate Cox regression analysis showed that IPI score, LDH value, β 2-MG value, ECOG score, LMR, and PLR had an significant effect on prognosis ( P<0.05 for all). Multivariate Cox regression analysis showed that lymphocyte/monocyte ratio and platelet/lymphocyte ratio were independent prognostic factors for diffuse large B-cell lymphoma ( P<0.05 for both). Conclusions:The R-CHOP-like chemotherapy regimen is superior to the CHOP-like regimen in the first-line treatment of patients with diffuse large B-cell lymphoma. ECOG score, LMR and PLR may be independent prognostic factors for diffuse large B-cell lymphoma. ECOG score, LMR and PLR are independent prognostic factors.
