Predicting One-Year Mortality in Older Cancer Patients: Performance of G8, SPPB, and IF-VIG in the PROFIT Study

The first aim was to compare, in a cohort study enrolling older adults (>65 years) with lung, gastrointestinal and prostate cancer, different easy measures of frailty (Geriatric 8 questionnaire (G8), Short physical Performance Battery (SPPB) and Índex de Fragilidad (IF-VIG), testing their ability to predict survival, functional status (ECOG, Barthel Index), quality of life (EuroQol5D) and resource utilization (visits, hospital admissions, treatments) at 3, 6 and 12 months.
