Lack of a caregiver is associated with shorter survival in myeloma patients undergoing autologous stem cell transplantation

Abstract

There is increasing evidence that social infrastructure and a healthy social network can improve cancer survival. Mayo Clinic has an outpatient stem cell transplantation program for myeloma. Safe outpatient transplantation requires a caregiver to be present. Patients lacking a caregiver are transplanted as an inpatient. We reviewed outcomes on over 2000 patients with multiple myeloma, 2103 transplanted as an outpatient compared with 41 hospitalized for transplantation. Although progression-free survival following transplantation was identical between the two groups, overall survival was shorter in those hospitalized. This suggests that the absence of a caregiver for transplantation is an important surrogate of the social infrastructure associated with poor outcomes in transplanted patients with multiple myeloma
