G8 Screening Tool Validation in Older Adults With Cancer in Portugal
Sponsor: Hospital de Braga
Summary
The G8 screening tool is widely recommended for the identification of frailty in older adults with cancer. However, prospective validation data in the Portuguese population are currently lacking. This prospective observational study aims to evaluate the diagnostic performance of the G8 screening tool compared with a Comprehensive Geriatric Assessment (CGA) in older adults with cancer. Patients aged ≥70 years with solid tumors will be assessed using both the G8 screening tool and a multidimensional CGA. Frailty will be defined as impairment in at least one CGA domain. The performance of the G8 will be evaluated in terms of sensitivity, specificity, and area under the receiver operating characteristic curve. This study aims to provide the first prospective validation of the G8 screening tool in Portuguese older adults with cancer and to support its implementation in clinical practice.
