INTRODUCTION: Patient reported outcomes (PROs) including symptoms and health related quality of life (HRQOL) predict mortality in multiple cancers, such as myeloma, head and neck, lung and prostate cancer. The relationship of PROs with survival is not clear in hematopoietic cell transplantation (HCT). We tested three hypotheses about the relationship between HRQOL and survival after HCT: (1) Pre-HCT HRQOL (particularly physical HRQOL) reflects functional status and predicts survival after allogeneic (allo) HCT independently of traditional risk factors and indices; (2) Post-HCT change in physical HRQOL reflects the “toll” of the HCT and predicts subsequent outcomes, including survival, among early survivors; (3) Since autologous (auto) HCT is associated with lower risks for treatment-related morbidity and mortality, PROs may not be as predictive for this group. METHODS: We tested these hypotheses using data from the 711 participants in BMT CTN 0902 (sponsored by NHLBI and NCI, NCT 01278927), a randomized study of pre-transplant exercise and stress management training for patients undergoing auto or allo HCT. Because the primary analysis for BMT CTN 0902 did not show a significant effect for exercise or stress management training, intervention groups were combined for these analyses. However, auto and allo recipients were analyzed separately because of the expected substantial differences in the subsequent risks for morbidity and mortality in the two populations. The HRQOL measures used were the physical component score (PCS) and mental component score (MCS) from the SF-36, measured pre-HCT and at day 100. RESULTS: Among 310 alloHCT recipients with a median follow-up of 23 months, while there were no pre-HCT clinical covariates (including age, conditioning intensity, donor type, graft source, disease, disease stage) that predicted survival, pre-HCT physical HRQOL (PCS on the SF-36) was strongly prognostic for survival (HR for death of 0.72 per 10 points increase, 95% CI 0.60-0.85, p
