Advances in targeting nano drug therapy and its carrier of colorectal cancer / 国际外科学杂志

ABSTRACT

Colorectal cancer is currently the world's fourth incidence of malignant tumors,the early clinical manifestations are not obvious,so the early diagnosis is difficult to find,most of them are in progress.Treatment of advanced stage with chemotherapy,interventional therapy,radiotherapy and other methods,in which chemotherapy in the killing of tumor cells at the same time,the normal cells of the body also has a killing effect.In recent years,all kinds of new nano targeting delivery system has been developed,which can be targeted to the tumor tissue,so it is more and more important in the treatment of intestinal tumor,especially with metastasis.The author has made an overview of the types of nano drug carrier materials,the research status and its application in the research of colorectal cancer.
