Non-myeloablative allogeneic hematopoietic cell transplantation (HCT) offers a potentially curative therapy for older patients with hematologic malignancies. However, the treatment modality is underutilized and, to date, there are only limited data on outcomes in people older than 60 years. This study describes the toxicities and outcomes of non-myeloablative allogeneic HCT, conditioned with low-dose total body irradiation with or without fludarabine, in patients aged 60-75 years enrolled in prospective multicenter clinical trials. Increasing age was not associated with adverse outcome. Relapse risk and comorbidity burden predicted survival; fit patients with low risk of disease relapse did well after transplant regardless of age. Despite demonstrating the feasibility of non-myeloablative allogeneic HCT in patients aged 60-75 years, the study raises important questions regarding how best to manage older patients with high-risk hematologic malignancies and how to optimize our approach to allogeneic HCT in this age group.
