Background: We performed a retrospective analysis of non-Hodgkin’s lymphoma (NHL) patients who received autologous stem cell transplant (ASCT) (n = 140) in our centre from 1992-2015. The study aimed to evaluate the patient outcomes based on age, NHL subtypes, and conditioning regimen.
Method: Data were gathered for this retrospective investigation using electronic records and case notes. Refractory illness, relapse, progressive disease, or death were all considered progression events. Time from ASCT to the last follow-up or progression event was used to define progression-free survival (PFS), and time from ASCT to death or the final follow-up was used to define overall survival (OS).
Results: Median age at ASCT was 55 years (16-68). Amongst patients ≤60 years (n = 109) and >60 years (n = 31), there was no significant difference in PFS (P = 0.756), OS (P = 0.711), neutrophil (12.5 vs 11 days) and platelet (12 vs 14 days) engraftment times. Amongst follicular lymphoma (FL) patients (n = 54) who received BEAM (carmustine, etoposide, cytarabine, melphalan) (n = 30) or Cy/TBI (cyclophosphamide/total body irradiation) (n=24) conditioning, there was no significant difference between PFS (P = 0.111) and OS (P = 0.667). There was no significant difference (P = 0.46) in the incidence of second malignancies in the patient receiving BEAM or TBI-based conditioning.
Conclusion: ASCT can be safely performed for NHL in patients >60 years with outcomes similar to those ≤60 years. TBI based conditioning appear safe with similar outcomes to BEAM in FL patients. Prospective studies are needed to confirm these findings.
