Abstract:
BACKGROUND: High-dose chemotherapy and autologous stem cell transplantation (ASCT) can offer durable remission in many patients with relapsed or high-risk lymphoma. However, elderly patients are often not considered ASCT candidates based on age alone. SUBJECTS, MATERIALS, AND METHODS: A retrospective analysis of patients ≥70 years of age with a diagnosis of Hodgkin or non-Hodgkin lymphoma receiving ASCT between 2000 and 2016 at two partner institutions was performed. Clinical data were extracted from institutional databases and individual medical records. Multivariate analysis was performed to examine the association of clinical variables with transplant outcomes. RESULTS: One hundred seven patients were identified. Median age at transplant was 72 years (range, 70-79). The most common lymphoma subtype was diffuse large B-cell (n = 63, 59%). Median time to neutrophil and platelet engraftment were 10 and 12 days, respectively. With a median follow-up for survivors of 20 months following ASCT (range, 6 months to 13.1 years), estimates for 2-year progression-free survival and overall survival were 58% (95% confidence interval [CI], 48%-67%) and 65% (95% CI, 55%-74%), respectively. Two-year estimate for relapse was 34% (95% CI, 25%-44%) and nonrelapse mortality (NRM) was 7% (95% CI, 3%-14%). Multivariate analysis showed that more recent date of transplant was associated with lower NRM. The Hematopoietic Cell Transplantation-Comorbidity Index score was not predictive of NRM in this data set (high-risk vs. low-risk, hazard ratio 3.45, p = .065). CONCLUSION: Eligibility for ASCT should be an individualized decision, and age should not be an absolute contraindication to ASCT in healthy elderly patients with lymphoma. IMPLICATIONS FOR PRACTICE: Although high-dose chemotherapy and autologous stem cell transplantation (ASCT) can offer durable remission in many patients with relapsed or high-risk lymphoma, elderly patients are often not considered candidates due to concern for excess toxicity and mortality. This retrospective study showed favorable transplant outcomes, including survival and toxicity, in a large cohort of lymphoma patients over 70 years of age who underwent ASCT. Eligibility for ASCT should be an individualized decision, and age should not be an absolute contraindication to ASCT in healthy elderly patients with lymphoma.
