Randomized trials have already demonstrated that geriatric intervention was able to improve survival in the general elderly population but only a few have been performed in cancer patients. At the end, these data are not sufficient to consider geriatric intervention as validated in this setting. Case Management, coordinated by a geriatrician and a trained nurse, could improve prognosis of elderly patients with cancer. This approach, can be integrated in daily oncology practice. This strategy will be compared to usual oncological management in a randomized phase III trial.
