[Colorectal cancer and preoperative geriatric assessment]

With the ageing of the population and the increase in the incidence of cancer in the population over 75 years of age, a partnership between geriatricians and oncologists is becoming necessary to optimise the management of these patients. There is great variability in the profiles of elderly patients and age cannot be the only criterion of the decision making. Thus, it is necessary to identify patients who will benefit from an in-depth geriatric assessment (IGA) and the G8 screening tool used in oncology consultations allows to do so. The EGA offers a multidisciplinary approach to functional, psychological, nutritional, cognitive and social status of the person, and has been shown to have prognostic value for survival and relevance in guiding treatment choices.
