Post-transplant cyclophosphamide (PTCy) has significantly increased the successful use of haploidentical donors with a relatively low incidence of graft-versus-host disease (GVHD). Given its increasing use, we sought to determine risk factors for GVHD after haploidentical hematopoietic cell transplantation (haplo-HCT) using PTCy. Data from the Center for International Blood and Marrow Transplant Research on adult patients with acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or chronic myeloid leukemia who underwent PTCy-based haplo-HCT (2013 to 2016) were analyzed and categorized into 4 groups based on myeloablative (MA) or reduced-intensity conditioning (RIC) and bone marrow (BM) or peripheral blood (PB) graft source. In total, 646 patients were identified (MA-BM = 79, MA-PB = 183, RIC-BM = 192, RIC-PB = 192). The incidence of grade 2 to 4 acute GVHD at 6 months was highest in MA-PB (44%), followed by RIC-PB (36%), MA-BM (36%), and RIC-BM (30%) (P = .002). The incidence of chronic GVHD at 1 year was 40%, 34%, 24%, and 20%, respectively (P < .001). In multivariable analysis, there was no impact of stem cell source or conditioning regimen on grade 2 to 4 acute GVHD; however, older donor age (30 to 49 versus

Predicting the duration of systemic therapy in patients with chronic graft-versus-host disease (cGVHD) is of critical clinical importance when counseling patients and for treatment planning. cGVHD characteristics associated with this outcome have not been studied in severely affected patients. The National Institutes of Health (NIH) cGVHD scoring provides a standardized set of organ severity measures that could represent clinically useful and reproducible predictive characteristics. We analyzed 227 previously treated patients most with moderate (n = 54) or severe (n = 170) cGVHD defined by NIH criteria who were prospectively enrolled in a natural history protocol (NCT00092235). Patients received a median of 4 prior systemic therapy regimens and were seen at the NIH for a single time-point visit and were then monitored for survival and ability to discontinue cGVHD systemic therapy. With a median follow-up of 71.1 months, the cumulative incidence of systemic therapy discontinuation was 9.5% (95% confidence interval, 6.0% to 13.9%) at 2 years and 27.7% (95% confidence interval, 20.9% to 34.8%) by 5 years after the initial visit. Factors associated with a higher incidence of immunosuppression discontinuation included lower NIH global severity (P = .019) and lung (P = .030) scores and less extensive deep sclerosis (37% body surface area, P = .024). Lower patient- and clinician-reported 0 to 10 severity NIH scores and noncyclosporine prophylaxis regimens were also associated with higher incidence of immunosuppression discontinuation (P .05). In conclusion, we found low success rates for immune suppression discontinuation in previously treated patients who were severely affected with cGVHD. NIH scoring and clinical measures provide new standardized disease-specific tools to predict discontinuation of systemic therapy.

Methods: The present study examined the association between fatigue, pain, overall quality of life, and perceived health status with employment at 1-year post-transplant. Participants (N1⁄4404) completed a lifestyle survey 1-year post-SCT. Participants provided current employment status and whether change was attributable to their health status. Results: Participants were predominatelymarried/partnered (81.7%), Caucasian/Non-Hispanic (81.6%), males (52%) between ages 19-76 (mean: 56 years) and majority underwent autologous transplants (70.1%). Prior to illness diagnosis, 60.8% were employed Full-Time, which decreased at the time of transplant (35.5%) and at 1-year post-SCT (31.0%). Employment status was correlated with all variables of interest (p
