Abstract: The coix ester and triglyceride are the main active ingredients with antitumor properties in semen coicis. Its therapeutic agent, the Kanglaite injection, is a new broad-spectrum type of antitumor diphase emulsion, which can be intravenously administered. In recent years, various studies have demonstrated that a good curative effect could be observed among the several chemotherapeutic regimens using the Kanglaite injection, particularly the non-small cell lung cancer and primary liver cancer, with only mild toxicity. Kanglaite injection can prevent the development of lung cancer, as well as increase the immunity of patients and enhance the clinical efficacy of other treatments. This thesis mainly studies the recent antitumor mechanisms and applications of KLT in the treatment of pancreatic malignant tumors.
