Abstract: This study introduces the antitumor mechanisms of Kanglaite injection and its applications in lung cancer surgery. The obvious curative effect of the treatment, as well as its safety, reliability, and low cost, can be assessed with positive results. Kanglaite injection can stop the development of lung cancer and help patients recover their health after the operation. The therapeutic effect of Kanglaite injection combined with cisplatin was better than when these treatments were used individually. In addition, the combined therapy had few adverse reactions. The positive curative effects of using Kanglaite injection were observed for several chemotherapeutic regimens, thus, further clinical applications are recommended.
