Abstract:
The G8 questionnaire is a geriatric screening tool recommended by the SIOG and the EAU. To save time and resources, it can precede a comprehensive geriatric assessment (CGA) in a two-step evaluation. Based on our experience, this 8-item questionnaire is easy and fast to perform (4 - 5 minutes), even by medical staff untrained in geriatrics. The G8 questionnaire has become an established screening tool also in geriatric oncology. It has been shown in several studies that it provides an independent prognostic indicator for the overall survival of cancer patients. However, some critical aspects remain: its low specificity (60 %), its focus on nutritional aspects, and possible interobserver differences. These aspects should be known and taken into account by clinicians.
