The 3-year cumulative incidence of disease-free survival (DFS) and severe GVHD-relapse-free survival (GRFS) were 71.4% and 55.6%, respectively. ES was significantly associated with the subsequent development of aGVHD, both grade II-IV (41.4% vs. 17.3% in those with and without ES, p=0.01) and grade III-IV (34.5% vs. 8.5% in those with and without ES; p=0.003). Chronic GVHD occurred at significantly higher rates in patients with prior Grade II-IV (66.7% vs. 0% for Grade 0-I; p<0.001) and Grade III-IV aGVHD (75% vs. 4.3% for Grade 0-II; p<0.001). Compared to non-obese patients, the PK model predicted lower melphalan exposure (p=0.02) in obese patients where adjusted ideal body weight was utilized, suggesting overcorrection of the dose. There was no impact of melphalan exposure on immunologic rejection. The median melphalan exposure was 6.81 mg*hr/L (range, 4.4-8.8). Compared to a melphalan exposure ≤6.8 mg*hr/L, a melphalan exposure >6.8 mg*hr/L was associated with a higher incidence of ES (48.8% vs. 19.1%; p=0.005), grade II-IV aGVHD (39.3% vs. 10.1%; p=0.002), and grade III-IV aGVHD (31.5% vs. 2.5%; p<0.001).

The prevailing model of psychosocial care in oncology is a brief consultation for patients who screen positive for distress at a particular timepoint. This model is insufficient for hematopoietic cell transplantation (HCT). Patients and caregivers have evolving needs throughout the HCT process, and psychosocial care models should meet these needs. This white paper, a collaboration between the Association of Oncology Social Work's Blood Cancer/HCT Special Interest Group and the American Society for Transplantation and Cellular Therapy's Social Work Special Interest Group, presents a gold standard model for the integration of social work in HCT. The model structures social work visits in every phase of HCT and integrates social workers within the interdisciplinary team. In this model, social workers conduct assessments with all patients (autologous and allogeneic) at the initial HCT consultation and again during work-up. They subsequently follow all patients and caregivers as they progress through transplant. This ongoing management reduces the burden on other team members to identify and address psychosocial needs. It also creates many organic opportunities to implement interventions to improve outcomes. There is a need to build institutional capacity for psychosocial care.
