Physical performance tests are a reflection of health in older adults.

The Timed Up and Go test is an easy-to-administer tool measuring physical performance.

In older adults undergoing oncologic surgery, an impaired TUG has been associated with higher rates of postoperative complications and increased short term mortality.

The objective of this study is to investigate the association between physical performance and long term outcomes.

Patients aged ≥65 years undergoing surgery for solid tumors in three prospective cohort studies, ‘PICNIC’, ‘PICNIC B-HAPPY’ and ‘PREOP’, were included. The TUG was administered 2 weeks before surgery, a score of ≥12 seconds was considered to be impaired.

Primary endpoint was 5-year survival, secondary endpoint was 30-day major complications. Survival proportions were estimated using Kaplan-Meier curves. Cox- and logistic regression analysis were used for survival and complications respectively.

Hazard ratios (aHRs) and Odds ratios (aOR) were adjusted for literature-based and clinically relevant variables, and 95% confidence intervals (95% CIs) were estimated using multivariable models.
