Abstract: Recently，maintenance therapy of traditional Chinese medicine（TCM）for advanced non-small cell lung cancer（NSCLC）has been carried out in many places of China. This paper trimmed the theoretical foundation，main content and the current situation of maintenance therapy，and summed up the literature of this field related to TCM in recent years. We obtained a result that TCM could relief clinical symptoms，prolong the progression-free survival，and improve the quality of life of advanced NSCLC. Meanwhile，there's some insufficiency in these studies，such as inadequate sample，low quality，and etc. We look forward to more highquality and normalized study.
