Frailty screening for predicting rapid functional decline, rapid progressive disease, and shorter overall survival in older patients with gastrointestinal cancer receiving palliative chemotherapy-a prospective, clinical study

Objectives: A growing number of older patients with cancer require well-founded clinical decision-making. Frailty screening is suggested as a service to improve outcomes in vulnerable older patients with cancer. This prospective study examined the value of frailty screening to predict rapid functional decline, rapid progressive disease (PD) and shorter overall survival (OS) in older patients with gastrointestinal cancer receiving palliative chemotherapy. Materials and Methods: Patients aged >= 70 years were screened for frailty in an oncologic department after clinical decision but before starting palliative chemotherapy. Screening was repeated at first response evaluation after approximately two months of chemotherapy. Frailty screening tools included performance status (PS), Charlson Comorbidity Index, G-8 using two different cut-offs (G8(14),G8(11)), VES-13, Timed-Up-and-Go, Handgrip strength and falls. Results: A total of 170 patients were included, median age was 75.5 (70-88) years and 65.9% were male. The frequency of frailty varied from 14% to 74% according to the chosen frailty tool. In multivariate analysis G8(14) predicted OS (HR 1.5; 95%CI 1.0-2.4), whereas G8(11) predicted PD (OR 2.4; 1.1-5.6) and OS (HR 2.1; 1.4-2.9). VES-13 predicted functional decline (OR 3.5; 1.0-11.6), PD (OR 3.5; 1.5-8.4) and OS (HR 1.7; 1.2-2.4). Timed Up-and-Go predicted OS (HR 1.8; 1.1-2.7). Handgrip strength and falls predicted functional decline (OR 4.5; 1.1-19 and OR 6.1; 1.4-25.8, respectively). PS predicted PD (OR 6.2; 2.6-14.7) and OS (HR 2.2; 1.5-3.2). Conclusion: VES-13 was useful for predicting all three endpoints of interest. Frailty tools covering domains of functioning and nutrition are suggested for older patients with advanced gastrointestinal cancer. (C) 2020 Elsevier Ltd. All rights reserved.

Automated summary

This study aimed to explore the predictive value of frailty screening in older patients with gastrointestinal cancer and found that different tools can predict different outcomes, suggesting the use of frailty tools covering multiple domains for these patients.
