Abstract

Background: Development of a geriatric screening tool is necessary to identify elderly cancer patients who would benefit from comprehensive geriatric assessment (CGA). We develop and evaluate the G-8 screening tool against various reference tests.

Patients and methods: Analyses were based on 364 cancer patients aged>70 years scheduled to receive first-line chemotherapy included in a multicenter prospective study. The G-8 consists of seven items from the Mini Nutritional Assessment (MNA) questionnaire and age. Our primary reference test is based on a set of seven CGA scales: Activities Daily Living (ADL), Instrumental ADL, MNA, Mini-Mental State Exam, Geriatric Depression Scale, Cumulative Illness Rating Scale-Geriatrics, and Timed Get Up and Go. We considered the presence of at least one questionnaire with an impaired score as an abnormal reference exam. Additional reference exams are also discussed.

Results: The prevalence of being at risk varied from 60% to 94% according to the various definitions of the reference test. When considering the primary reference test, a cut-off value of 14 for the G-8 tool provided a good sensitivity estimate (85%) without deteriorating the specificity excessively (65%).

Conclusion: The G-8 shows good screening properties for identifying elderly cancer patients who could benefit from CGA.
