Abstract
BACKGROUND Evidence about the impact of marital status before hematopoietic cell transplantation (hct) on outcomes after hct is conflicting. METHODS We identified patients 40 years of age and older within the Center for International Blood and Marrow Transplant Research registry who underwent hct between January 2008 and December 2015. Marital status before hct was declared as one of: married or living with a partner, single (never married), separated or divorced, and widowed. We performed a multivariable analysis to determine the association of marital status with outcomes after hct. RESULTS We identified 10,226 allogeneic and 5714 autologous hct cases with, respectively, a median follow-up of 37 months (range: 1-102 months) and 40 months (range: 1-106 months). No association between marital status and overall survival was observed in either the allogeneic (p = 0.58) or autologous (p = 0.17) setting. However, marital status was associated with grades 2-4 acute graft-versus-host disease (gvhd), p < 0.001, and chronic gvhd, p = 0.04. The risk of grades 2-4 acute gvhd was increased in separated compared with married patients [hazard ratio (hr): 1.13; 95% confidence interval (ci): 1.03 to 1.24], and single patients had a reduced risk of grades 2-4 acute gvhd (hr: 0.87; 95% ci: 0.77 to 0.98). The risk of chronic gvhd was lower in widowed compared with married patients (hr: 0.82; 95% ci: 0.67 to 0.99). CONCLUSIONS Overall survival after hct is not influenced by marital status, but associations were evident between marital status and grades 2-4 acute and chronic gvhd. To better appreciate the effects of marital status and social support, future research should consider using validated scales to measure social support and patient and caregiver reports of caregiver commitment, and to assess health-related quality of life together with health care utilization.

Abstract
BACKGROUND Follow-up is integral for hematopoietic cell transplant (HCT) care to ensure surveillance and intervention for complications. We characterized the incidence of, and predictors for, being lost to follow-up. METHODS Two-year survivors of first allogeneic (10,367 adults and 3,865 children) or autologous (7,291 adults and 467 children) HCT for malignant/non-malignant disorders from 2002-2013 reported to the Center for International Blood and Marrow Transplant Research were selected. The cumulative incidence of being lost to follow-up (defined as having missed 2 consecutive follow-up reporting periods) was calculated. Marginal Cox models (adjusted for center effect) were fit to evaluate predictors. RESULTS The 10-year cumulative incidence of being lost to follow-up among adult allogeneic and autologous HCT survivors was 13% (95% CI, 12-14) and 15% (95% CI, 14-16), respectively. Among pediatric HCT survivors, estimates were 25% (95% CI, 24-27) and 24% (95% CI, 20-29), respectively. In adult allogeneic HCT survivors, younger age, non-malignant disease, public/no insurance (reference: private), living farther from the HCT center, and being unmarried were associated with being lost to follow-up. For adult autologous HCT survivors, older age and testicular/germ cell tumor (reference: non-Hodgkin lymphoma) were associated with greater risk of being lost to follow-up. Among pediatric allogeneic HCT survivors, older age, public/no insurance (reference: private), and non-malignant disease were associated with being lost to follow-up. Among pediatric autologous HCT survivors, older age was associated with greater risk of being lost to follow-up. CONCLUSION Follow-up focusing on minimizing attrition in high-risk groups is needed to ensure surveillance for late effects.
