We propose to perform a prospective and randomized study to evaluate the impact of a CGA with GIP in 70 years old and more patients with a thoracic, digestive or urologic cancer resection, respectively 1, 3, 6 and 12 months after discharge. CGA and GIP will focus on 8 distinct fields: autonomy, co-morbidities, co-medication, mobility, nutritional status, depression, cognitive function and social status. The impact of such a strategy on autonomy and survival has never been studied.
