Frailty screening by Geriatric-8 and 4-meter gait speed test is feasible and predicts postoperative complications in elderly colorectal cancer patients.

Introduction: Identification of frail older colorectal cancer patients might help to select those prone to adverse events and may lead to adjustment of treatment plans. However, the prognostic validity of screening for frailty is unknown.

Methods: This retrospective study evaluates colorectal cancer patients ≥70 years who underwent elective surgery between May 2016 and December 2018.
