Feasibility and Implementation of a Multimodal Supportive Care Program to Improve Outcomes in Older Patients Undergoing Allogeneic Stem Cell Transplantation.

Increasingly, patients age ≥65 years are undergoing allogeneic hematopoietic stem cell transplantation (allo-SCT). Although age alone is a well-documented predictor of overall survival (OS) and nonrelapse mortality (NRM), growing evidence suggests that poor functional status and frailty associated with aging may have roles as well. Our goal in the present study was to identify and improve these and other aging-related maladies by developing a multimodal supportive care program for older allo-SCT recipients. We designed and implemented a multimodal supportive care program, Enhanced Recovery in Stem Cell Transplant (ER-SCT), for patients age ≥65 years undergoing allo-SCT. The ER-SCT program consists of evaluation and critical interventions by key health care providers from multiple disciplines starting before hospital admission for transplantation and extending through 100 days post-allo-SCT. We determined the feasibility of implementing this program in a large stem cell transplantation center. After 1 year of ongoing process improvements, multiple evaluations, and enrollment, we found that a dedicated weekly clinic was necessary to coordinate care and evaluate patients early. We successfully enrolled 57 of 64 eligible patients (89%) in the first year. Our data show that a multimodal supportive care program to enhance recovery for older patients undergoing allo-SCT is feasible. © 2021 American Society for Transplantation and Cellular Therapy.

Hemorrhagic cystitis after allogeneic hematopoietic stem cell transplants is the complex result of BK virus infection, preparative regimen intensity and donor type.

BACKGROUND: Hemorrhagic cystitis is a common cause of morbidity after allogeneic stem cell transplantation, frequently associated with BK virus infection. We hypothesized that patients with positive BK viruria before unrelated or mismatched related donor allogeneic hematopoietic stem cell transplantation have a higher incidence of hemorrhagic cystitis. DESIGN AND METHODS: To test this hypothesis, we prospectively studied 209 patients (median age 49 years, range 19-71) with hematologic malignancies who received bone marrow (n=78), peripheral blood (n=108) or umbilical cord blood (n=23) allogeneic hematopoietic stem cell transplantation after myeloablative (n=110) or reduced intensity conditioning (n=99). Donors were unrelated (n=201) or haploidentical related (n=8). RESULTS: Twenty-five patients developed hemorrhagic cystitis. Pre-transplant BK viruria detected by quantitative PCR was positive in 96 patients. The one-year cumulative incidence of hemorrhagic cystitis was 16% in the PCR-positive group versus 9% in the PCR-negative group (P=0.1). The use of umbilical cord blood or a haploidentical donor was the only significant predictor of the incidence of hemorrhagic cystitis on univariate analysis. There was also a trend for a higher incidence after myeloablative conditioning. Multivariate analysis showed that patients who had a positive PCR pre-transplant and received haploidentical or cord blood grafts with myeloablative conditioning had a significantly higher risk of developing hemorrhagic cystitis (58%) than all other recipients (7%, P<0.001). CONCLUSIONS: Hemorrhagic cystitis is the result of a complex interaction of donor type, preparative regimen intensity, and BK viruria.
