Pulmonary metastatic tumors are mainly treated by surgical resection of metastatic tumors, supplemented by chemotherapy, radiotherapy, Chinese medicine and other comprehensive treatments to prolong the survival cycle of patients. The general surgical choice tends to be conservative and advocates the so-called economic resection, which means preserving the patient’s normal lung tissue as much as possible and improving the postoperative quality of life as long as the metastases can be completely removed. Lung wedge resection has become the standard surgical procedure for the surgical treatment of most types of lung cancer metastases. The other is minimally invasive, which is also the current trend of development, and the application of lung metastases treated by televised laparoscopic surgery is also gaining attention, with the dual role of confirming the diagnosis and treatment.
