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

Overview

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.

The impact of the aging of population on cancer incidence and consequences is clear: in very few years, more than 50% of older adults will be diagnosed with malignant tumors, with a relevant increase in mortality compared to younger adults, and a dramatic burden of disability. Many of these patients will be potential candidates for oncospecific treatments, either curative, adjuvants or palliative. Despite this scenario, many trials on cancers still exclude patients based on their age or set survival and treatments' toxicity as the main outcomes, neglecting other meaningful outcomes such as functional status or quality of life. Therefore, clinical decisions regarding this specific population are not always based on real-life data. Moreover, older adults are a highly heterogeneous population, based on clinical, functional, and psychosocial aspects. This is why, in such a population group, the individualization of treatments is pivotal. Frailty has been proposed as a better marker of biological age than chronological age. This concept indicates a reversible state of risk of increased vulnerability to external or internal stressors, exposing the patients to a higher risk of adverse events, including disability and mortality. However, there is no agreement on the most suitable frailty tools to be used in practice. In older adults with cancer, frailty, which is easily measured in any setting through quick clinical scales, could be an ideal trigger to select candidate patients for a subsequent more extensive comprehensive geriatric assessment (onwards, CGA) and potential interventions. Among these interventions, multi-component approaches including physical exercise and nutritional recommendations have shown a positive impact on both mortality and functional status in patients with different cancers and could be proposed for either pre-habilitation or re-habilitation in older cancer patients with mild-moderate frailty. Considering these premises, 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 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. The PROFIT study will add relevant evidence for the management of older cancer patients. The impact, for the individual and the society, is high, in light of the aging of the population: the results will allow providing oncologists and other professionals with tools to improve the personalization of treatments, to finally provide adequate and tailored care programs. This might contribute to avoid the exclusion of patients who could benefit from active treatments and, on the other hand, reducing overtreatment for those who will likely not benefit from it. The clinical trial will also provide information on the most suitable content and on the impact of an intervention aimed at strengthening the functional status and improving the quality of life in older cancer patients with mild-moderate frailty, who might be potential candidates for subsequent onco-specific treatments. The project will also deliver adapted materials and eHealth solutions to be potentially scaled up for this profile of users, as a benefit for the society even beyond this project.
