Does the eastern cooperative oncology group performance status scale affect physical activity of patients undergoing allogeneic hematopoietic stem cell transplantation in a bioclean room?

Purpose: The aim of this study was to examine the criterion validity of the Eastern Cooperative Oncology Group Performance Status Scale (ECOG PS) for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) in a bioclean room. Subjects: The participants were 27 HSCT patients (13 males, 14 females, mean age 47 ± 14.1 years). Methods: We assessed the relationship between ECOG PS Grade 1-3 and the mean daily steps measured with a pedometer. Results: The mean daily steps of grades 1 to 3 were 2,411 ± 1,068, 1,205 ± 572, and 597 ± 216 steps/day, respectively, with a statistically significant correlation. [Conclusion] ECOG PS is a simple and valid tool for assessing the overall condition of HSCT patients in a bioclean room.
