Advance of surgery for non-small-cell lung cancer with limited liver metastases / 中华胸心血管外科杂志

ABSTRACT

Objective Lung cancer has been the most common cause of cancer death worldwide.More than three quarters is diagnosed at advanced stage.Nearly one half has distant metastases outside the chest cavity.It has been recognized that oligometastatic state exists in natural history of malignant tumors,which has significantly better prognosis than those with polymetastases.The eighth edition of TNM staging system defined NSCLC with a single metastasis as a new separated stage(M1 b).Long-term survival of oligometastatic NSCLC patients treated with local control methods has been reported in literatures.But whether surgical resection of liver metastasis has benefit or not remains unknown.We performed a systematic review of surgical therapy for NSCLC with limited liver metastases.
