Results from a multidisciplinary clinic guided by geriatric assessment before stem cell transplantation in older adults

Abstract

AbstractLimitations found on geriatric assessment (GA) track with worse outcomes after hematopoietic cell transplantation (HCT). We report on a multidisciplinary team clinic (MDC), consisting of a cancer-specific GA and a multidisciplinary team of providers, to assess candidacy and create an individualized optimization plan for allogeneic HCT candidates aged ≥60 years and autologous HCT and adoptive T-cell therapy candidates aged ≥70 years. Among the 247 patients evaluated in the MDC, allogeneic HCT candidates comprised the majority (60%), followed by autologous HCT (37%) with occasional older cellular therapy candidates (3%). Almost all patients meeting program-required minimum ages for MDC optimization at our institution were assessed (98%). Relative to historical control subjects undergoing GA alone, allogeneic HCT patients aged ≥60 years who underwent MDC appraisal had similar frequencies of high-risk disease, reduced intensity regimens, and high comorbidity but fewer GA-graded functional impairments. The MDC cohort experienced fewer inpatient deaths, shorter length of stay, and fewer discharges to nursing facilities compared with control subjects. Improvements in early mortality were observed over time; 1-year overall survival improved from 43% in the pre-MDC era to 70% in the recent MDC era, and 1-year nonrelapse mortality decreased from 43% to 18%. The 31 autologous HCT recipients aged ≥70 years optimized by the MDC achieved 0% nonrelapse mortality and 97% overall survival at 1 year. A GA-guided MDC for older HCT candidates is feasible and seems to reduce transplant-associated morbidity and mortality. An MDC should encourage broader and safer utilization of transplantation in older patients.
