This is a study that evaluates an optimization of the monitoring of patients with lung cancer in order to extend the survival of patients by improving their quality of life and decreasing anxiety generated by the achievement of balance sheets imaging. The spacing of the follow-up imaging also helps to reduce the cost of such monitoring. The main objective of this study is to evaluate the overall survival of patients.

With a 5-year survival of about 15% pulmonary cancer is very poor prognosis. About 70 to 75% of cancers are diagnosed at advanced stages. Relapses are common and rarely curable. At least 75% of relapses are symptomatic and there is no standard monitoring after curative treatment or not. Currently, the most common monitoring strategy involves the completion of a clinical examination every 3 to 6 months associated with chest X-ray or CT-scan.

An intensive clinical and imaging monitoring has not yet shown any survival advantage but monitoring of symptoms appears to have a significant medical and economic advantage compared to imaging monitoring. This non-personalized approach is a source of anxiety for patients, especially with the approach of the date of the imaging assessment. In contrast, this monitoring can leave symptomatic patients with untreated relapse for several weeks because many symptomatic patients wait the date of the imaging assessment to consult.

the investigators have developed a score based on the dynamics and the association of clinical signs to alert the physician to a possible recurrence of lung cancer. The referring physician is alerted so early and convenes the patient for a checkup. One of the explanations which could demonstrate the gain in survival is the possibility offered by the application SENTINEL is to treat the relapses earlier, thus avoiding to wait a too much important deterioration of general condition between two monitoring follow-up more or less spaced.
