Geriatric assessment and the variance of treatment recommendations in geriatric patients with gastrointestinal cancer-a study in AIO oncologists.

The higher variance of treatment recommendations indicates that it is less likely for elderly patients to get the optimal recommendation. Although the proposed therapeutic regimen varied higher in elderly patients and the oncologists rated the GA results as 'useful', the GA results did not influence the individual recommendations or its variance. Continuing education on GA and research on implementation into clinical practice are needed.
