Abstract:
Introduction Non-pegylated liposomal doxorubicin (NPLD) is considered a good alternative to conventional doxorubicin for the treatment of older patients (pts) with aggressive lymphomas and/or at high risk for cardiological toxicity. The use of R-COMP for the treatment of older pts with DLBCL has been supported by several small retrospective studies . In this report we describe the characteristics and outcomes of pts who were prospectively enrolled in the Elderly Project (EP) and who were treated with R-COMP and compared them with pts treated with conventional R-CHOP. Methods. This analysis was conducted starting from the dataset of the EP study. The use of NPLD was allowed according to 648/96 law, treatment decision was left to physician discretion and was independent of frailty status. For the purposes of this analysis, we included all pts who were treated with full doses of R-CHOP and R-COMP. The study endpoint were progression free survival (PFS) and overall survival (OS). A propensity score analysis was conducted to account for the main confounding factors. Results Overall 691 out of 1163 pts of the EP were treated with R-CHOP (383; 55%) or R-COMP (308; 45%); median age was 71 and 76 years for R-CHOP and R-COMP, respectively (p & lt; 0.001) (Table 1). Pts were similarly distributed among different IPI groups for R-COMP or R-CHOP. Based on simplified Geriatric Assessment (sGA) 88%, 11% and & lt;1% of the R-CHOP treated pts and 61%, 32% and 6% of the R-COMP pts were FIT, UNFIT, and FRAIL (p & lt;0.001). Elderly Prognostic Index (EPI) score was low, intermediate, and high in 39%, 54% and 8% of R-CHOP pts and 27%, 49% and 24% of R-COMP pts (p & lt;0.001). PFS at 3-years was 70% for R-CHOP and 64% for R-COMP (p=ns). OS at 3-years was 77% for R-CHOP and 71% for R-COMP (p=ns). The propensity score analysis was conducted in 610 pts and confirmed no significant differences in terms of PFS and OS in the comparison between R-CHOP and R-COMP treated pts (PFS; HR 1.17, 95% CI 0.84-1.63; OS: HR 1.04 95% CI 0.64-1.48). No differences were registered in terms of interruption of treatment due to toxicities (7% for R-CHOP and 11% for R-COMP). Conclusions Data from the prospective observational EP study did not show significant differences in terms of efficacy comparing R-COMP to standard R-CHOP. The higher frequency of UNFIT and FRAIL pts among those treated with NPLD suggests R-COMP is a good strategy to offer a curative treatment to these groups of pts. Figure 1 Figure 1.
