Associations of physical activity and sedentary time with health-related quality of life in patients with localized renal cell cancer: a cross-sectional analysis within the ReLife study.

Purpose: This study examined the associations of device-measured moderate-to-vigorous physical activity (MVPA) and sedentary time as well as self-reported MVPA with health-related quality of life (HRQoL) in patients with localized renal cell cancer (RCC) in the recovery phase after surgery.

Methods: At 3 months post-surgery, 341 patients with stage I-III RCC participating in the ReLife study wore an ActivPAL3 device to determine MVPA and sedentary time. The SQUASH questionnaire was used for assessing self-reported MVPA, and the EORTC QLQ-C30 for assessing HRQoL (range 0-100).
