Participants

Questionnaires are sent annually to transplant survivors as part of the Fred Hutchinson Cancer Research Center (FHCRC) long-term follow-up research program. Non-responders to the initial survey are sent a reminder letter 1 month later. All patients who underwent allogeneic transplantation from any graft source at FHCRC and who consented to allow their information to be used for research purposes were included. Patients were aged 18 or greater at the time of the survey. The analyzed data were from surveys administered by mail or online, according to the participants’ choice, from July 1, 2015 to June 30, 2016. The dataset was sealed as of September 30, 2016. The Institutional Review Board of FHCRC approved the study, and all patients provided written informed consent at the time of their transplants.
