Functional impairment prior to major non-cardiac surgery is associated with mortality within one year in elderly patients with gastrointestinal, gynaecological and urogenital cancer: A prospective observational cohort study

Objective: To investigate the prognostic value of elements of the Geriatric Assessment, in particular the Timed Up and Go (TUG) Test and the Barthel Index of Activities of Daily Living (ADL) for one-year post-operative mortality in elderly patients with cancer. Materials and Methods: This prospective cohort study included patients 65 years of age or older undergoing elective major surgery for cancer between June 2008 and June 2010. Preoperative functional status was measured by the TUG Test and the Barthel Index of ADL Cognitive state was assessed by the Mini Mental State Examination (MMSE). Complications were recorded prospectively. The degree of resection was noted. Results: Data from 131 patients (56% women; median age, 71 years) were analysed at 1 year of follow-up. Mortality after 1 year was 282%. Twenty-nine patients (22.3%) were dependent in ADLs, and 43 (35.2%) impaired in TUG. Thirteen patients (10.7%) were both, dependent in ADIs and impaired in TUG. Short-term complications after surgery occurred in 66% of patients, and major complications occurred in 29%. Patients who were dependent in ADLs and impaired in TUG had significantly higher 1-year mortality (OR, 4.5; 95% CI, 1.21-18.25; p = 0.034). Lower scores on the MMSE (OR, 0.64; 95% CI, 0.43-0.95; p = 0.048) and incomplete surgical resection (OR, 325; 95% CI, 1.15-9.20; p = 0.026) were independently associated with higher 1-year mortality. Conclusion: Functional assessments, such as ADL and TUG scores, as well as mild cognitive impairment, are predictors of long-term outcome in elderly cancer patients. (C) 2017 The Authors.
