  • Abstract The conditional survival of patients after frontline therapy for diffuse large B-cell lymphoma (DLBCL) approaches that of the general population once patients have survived disease free for 2 years. We sought to determine the conditional survival of patients among patients with relapsed de novo DLBCL successfully undergoing an autologous stem-cell transplant (ASCT) after first relapse. A total of 478 patients with de novo DLBCL, relapsed after 1 treatment from the Collaborative Trial in Relapsed Aggressive Lymphoma (CORAL) and LY.12, were included. Patients were followed prospectively after ASCT for a median of 5.3 and 8.2 years, respectively. Individual patient data were analyzed for event-free survival (EFS) and overall survival. Standardized mortality ratios (SMRs) were estimated using French and Canadian life tables. The EFS estimates declined with each year of follow-up after ASCT and were 50.1% (95% confidence interval [CI]: 43.7% to 56.3%) and 43.4% (95% CI: 36.7% to 49.9%) at 5 years in CORAL and LY.12, respectively. The rate of death stabilized once patients achieved at least 4 years of EFS. Compared with the age- and sex-matched population, the SMR was significantly higher until 5 years after ASCT, when values were no longer statistically significant. Patients undergoing ASCT for relapsed DLBCL continue to have a higher rate of death at least until they have survived event free for 5 years. These observations can help to determine endpoints for future clinical trials in this population and for patient counseling. This trial was registered at as #NCT00078949.
