The goal of this observational study is to identify and describe the clinical characteristics, health status, socio-economic impacts and quality of life of patients alive for three years after diagnosis of metastatic Lung cancer and no longer receiving cytotoxic chemotherapy. The main question is to identify the needs of these patients in terms of health status (impact of cancer treatments, incidence of new diseases, cardiovascular, diabetes, second cancers), socio-economic aspects, quality of life and return to employment.

Participants will be asked to answer quality of life questionnaires at the time of inclusion and 6 and 12 months after inclusion and then, every year up to 5 years in this study.

They will be followed regularly, in consultations, according to the usual practices of the physicians in each participating center.

Inclusion Criteria:

• Patient over 18 years old
• Patients alive after more than three years from diagnosis with stage IV or Stage III NSCLC or SCLC, not treated with cytotoxic chemotherapy at the time of inclusion (the patient may be undergoing imunotherapy, targeted therapy or surveillance).
• Patients covered by the French National Health Insurance program or with thirdparty-payer health insurance

Exclusion Criteria:

• Difficulties for understanding French
• Patients undergoing treatment with cytotoxic chemotherapy
• Patients under legal guardianship, under curatorship or tutorship
• Insufficient cognitive capacity to answer questions
• Inability to obtain data collection (lost to follow-up, patient's refusal for data collection)
• Patients refusing the collection of their data (an information sheet will be provided)

Patients will be recruited by GFPC centers which is a large French network of hospitals and clinics particularly active in pneumology and thoracic oncology centers participating in clinical research.

The principal investigator in each center will identify consecutive patients eligible for inclusion. Patients will be asked to confirm their consent for data collection.
