Validation of the G8 Screening Tool for Prognostic Assessment of Frailty and Early Mortality in Elderly Individuals With Cancer: Prospective Cohort Study in Brazil - CORALINE (LACOG 0625)
This is a prospective observational cohort study including 250 individuals aged 70 years or older newly diagnosed with solid tumors. In this non-interventional study, all patient contacts will be conducted via telephone or video call.
After obtaining informed consent which will be conducted electronically, an initial telemedicine assessment will be performed. During this evaluation, sociodemographic and clinical data will be collected, and a Comprehensive Geriatric Assessment (CGA) will be conducted. The assessment will be performed by a trained professional using internationally recognized, validated instruments that are preferably culturally adapted to the Brazilian population. The G8 score will be calculated based on information collected at baseline. Additionally, medication use, the Charlson Comorbidity Index, Mini Nutritional Assessment, and self-rated health status will be recorded. The total G8 score ranges from 0 to 17, with higher scores indicating better health status (abnormal G8 score ≤14).
調査の概要
詳細な説明
There will be no access to or review of medical records in this study; all information will be obtained directly from participants through telemedicine assessments and follow-up contacts.
Participants will continue to receive treatment and clinical evaluations as determined by their treating physicians, according to standard clinical practice.
No intervention is proposed in this study.
Participants will be contacted for follow-up at 3, 6, 12, 18, 24, and 36 months.
During follow-up, information regarding treatment continuation, treatment discontinuation due to toxicity, and survival status will be collected.
The primary endpoints are overall survival and early mortality, defined as death occurring within six months after study inclusion, as well as overall survival at 1 year and 3 years.
Following approval by the Research Ethics Committee, the study will be conducted in a decentralized manner, with recruitment occurring through spontaneous demand or referral by treating physicians from different institutions, preferably among investigators affiliated with LACOG who are aware of the study protocol.
