PeRsonalizing the Approach to the Oncologic Frail Individual Through Tailored Assessment and Intervention (PROFIT Study)

The PROFIT study has two complementary aims. The first aim is to compare, in a cohort study enrolling N=257 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 the IF-VIG), testing their ability to predict survival, functional status (ECOG, Barthel Index), quality of life (EuroQol5D) and resources utilization (visits, hospital admissions, treatments) at 3, 6 and 12 months. The second aim, which motivates the registration in ClinicalTrials.gov, is to conduct a randomized controlled trial (RCT) enrolling N=134 patients per group, with similar characteristics to those enrolled for aim 1, but with mild-moderate frailty (G8≤14 points); we will compare a multi-component CGA-based intervention including physical exercise and nutritional recommendations with usual care, measuring the impact on the same outcomes as for aim 1, at 3 and 6 months. The use of ad hoc eHealth solutions (App/platform for exercise) will foster patients' empowerment and sustainability of the intervention. We will also assess patients, caregivers, and professionals' experience with the intervention through focus groups. Participants will be recruited from outpatients and from post-acute care units.
