Abstract

Allogeneic hematopoietic cell transplantation (HCT) can potentially cure indolent non-Hodgkin lymphoma (NHL). However, the optimal timing and indications remain unclear. Here, we review recent published reports on the subject and summarize our approach.Recent prospective clinical trials of allogeneic HCT in indolent NHL are marked by substantial variation in eligibility criteria, patient populations, and transplant approach. Nonetheless, several common themes are apparent. Indolent NHL is highly susceptible to immunologic graft-versus-lymphoma effects and relapse rates after allogeneic HCT are uniformly low. Allogeneic HCT early in the disease course produces the highest overall and progression-free survival, but also increases patient exposure to potential transplant-related complications such as chronic graft-versus-host disease. In contrast, allogeneic HCT can be reserved as a 'last resort' for patients who are refractory to conventional chemotherapy, delaying their exposure to graft-versus-host disease and other transplant-associated risks. No trials have directly addressed the optimal timing of allogeneic HCT in indolent NHL nor prospectively compared different transplant approaches.Excellent outcomes have been reported with allogeneic HCT for indolent NHL, both early and late in the disease course. The optimal timing of allogeneic HCT is unknown and depends heavily on patient preferences.
