Objective: In this study, we aimed to report the effectiveness of hematopoietic cell transplantation–specific comorbidity index (HCT-CI) and GATMO scores in predicting overall survival (OS) who underwent autologous stem cell transplantation (ASCT). Material and methods: The data of 263 MM and 204 lymphoma patients who underwent ASCT in the last 11 years were retrospectively analyzed. Results: Neutrophil engraftment time, thrombocyte engraftment time and collected CD34+ cell counts were similar in MM patients with HCT-CI>2 and HCT-CI≤2 (all p>0.05). Although the estimated median OS of MM patients with HCT-CI ≤2 tended to be higher than those with HCT-CI>2, this difference was not statistically significant (52.8 vs 45 months, p=0.172). No effect of GATMO score on CD34 + count, engraftment times and OS in MM patients was detected (p>0.05). The effect of HCT-CI score on lymphoma patients was examined, it was found that the neutrophil engraftment time was longer (p=0.039) and the number of collected CD34+ cells was lower (p=0.02) in patients with HCT-CI>2 than those with HCT-CI≤2. While the estimated median OS of lymphoma patients with HCT-CI≤2 was 51.5 months, the estimated median OS of patients with HCT-CI>2 was 9.5 months (p=0.012). When lymphoma patients were divided into four groups according to their GATMO scores, the OS of the four groups was found to be different from each other (p<0.001). Conclusion: HCT-CI and GATMO scores predict OS in lymphoma patients but not MM patients. © 2021 Elsevier Ltd |
