Oligometastasis represents a transitional state between early localized disease and widespread metastasis, characterized by limited tumor burden and distinct tumor biological behavior. Due to the relatively restricted number of metastatic lesions and involved organs, aggressive systemic therapy combined with local consolidative therapy offers potential for cure. With rapid advancements in molecular targeted therapies and immunotherapy, comprehensive management of oligometastatic non-small cell lung cancer (NSCLC) has gained increasing attention. This review summarizes the definition of NSCLC oligometastasis, recent therapeutic progress, and existing challenges, aiming to provide insights for clinical diagnosis and treatment strategies.
