The study is a retrospective observational study. The study is designed to be multicentric and it will analyze medical records from selected patients that underwent major lung resection using DaVinci surgical platform performed in the participating centers.

There are no risks for the patients, as this is a retrospective data collection.

The investigators will recruit all patients who underwent major lung resection (segmentectomy, lobectomy, bilobectomy, or pneumonectomy using a robotic system) from May 2015 to December 2022.

Patients are divided into two groups: older than 80 years (case- very elderly patients) and younger than 80 years (control- elderly).

the aim: Minimally invasive techniques such as robot-assisted thoracoscopic surgery (RATS) can potentially reduce surgical trauma and therefore prove particularly beneficial for elderly patients.

Inclusion Criteria:

• Age >18 years at the moment of surgery
• Suspected or confirmed diagnosis of lung cancer
• The patient can be candidate in terms of cardiac, kidney, liver and respiratory function the primary pathology is under control or controllable
• Absence of extrapulmonary metastases that are not controlled or controllable
• All procedures included use of DaVinci robot system

Exclusion Criteria:

• Age < 18 years at the moment of surgery
• Patients who cannot undergo surgery, as they do not meet the conditions outlined above

the study will focus on the population of subjects undergoing lung resection with the DaVinci surgical platform from May 2015 to December 2022.

The anatomical resections considered will be segmentectomy, lobectomy, bilobectomy or pneumonectomy using robotic system.
