The curative treatment of thoracic (lung and oesophagus), digestive (gastric, pancreatic, hepatic, colorectal), and urologic (renal, bladder, prostatic) cancers needs a surgical resection. For patients aged of 70 years old and more, this surgery is associated to an increased morbid-mortality especially because of more frequent co-morbidities. Comprehensive geriatric assessment (CGA) allows distinguishing patients for whom a resection surgery can be complicated by high morbid-mortality or a loss of autonomy. It has been proved that for old patient population without cancer, CGA associated with a geriatric intervention plan (GIP) allows autonomy preservation, decrease of institution admission, and survival improvement. The reference study showed that a CGA associated to a GIP improves survival of old patients who had a cancer surgery. However this study included patients from 60 years old and the GIP consisted in 3 home visits and 5 phone calls during the 4 weeks following hospital discharge.

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.
