Indications and developments of video-assisted thoracic surgery in the treatment of lung cancer

The term video-assisted thoracic surgery (VATS) is used to describe a modern minimally invasive surgical technique that nowadays represents a valid alternative to open procedures (i.e., thoracotomy) for many chest diseases. The VATS approach is presently used in many intrathoracic disorders, but while well established in benign chest disease, its role continues to evolve regarding the management of lung cancer. It is currently considered for the evaluation and treatment of suspected (or known) pleural effusion and in the diagnosis of indeterminate pulmonary nodules, and it has a complementary role to standard cervical mediastinoscopy in the invasive staging of mediastinal lymph nodes. It has also become an accepted approach for resection of peripheral early-stage lung cancer (stage I) in many centers worldwide and considerable experience has been accumulated in respect to this field, but absolute indications have yet to be firmly defined. This paper reviews indications and current data regarding minimally invasive approaches for the staging and treatment of lung cancer
