Key clinical point: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) led to acceptable survival outcomes in patients with relapsed or refractory diffuse large B cell lymphoma (DLBCL), particularly in those achieving a partial or complete response to chemotherapy before allo-HSCT.
Major finding: At a median follow-up of 38.3 months, the estimated 5-year overall survival and event-free survival rates were 38.4% (95% CI 24.7%-51.8%) and 30.6% (95% CI 18.8%-43.3%), respectively, with patients who achieved a partial or complete response before allo-HSCT having overall survival and event-free survival rates of 54.1% (95% CI 34.2%-70.3%) and 46.4% (95% CI 28.1%-62.9%), respectively.
Study details: This retrospective study included 52 adult patients with relapsed or refractory DLBCL who either had an active disease status or achieved a partial or complete response before transplantation and underwent allo-HSCT.
Disclosures: This study did not disclose any funding source. The authors declared no conflicts of interest.
