Approach for oligometastasis in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) harboring a limited number of distant metastases, referred to as the oligometastatic state, has been indicated for surgery for the past several decades. However, whether the strategy of surgical treatment results in a survival benefit for such patients remains controversial. Experientially, however, thoracic surgeons often encounter long-term survivors among surgically resected oligometastatic NSCLC patients. In this article, the current situation of surgical approach and potential future perspective for oligometastatic NSCLC are reviewed.
