| Outline of Final Research Achievements |
In order to develop a minimally invasive treatment for lymph node(LN) metastasis of oral cancer, a lymphogenous anticancer drug administration method using a LN upstream in the lymph network as a drug administration site was examined. In this study, MXH10 / Mo / lpr which is a lymph node swollen mouse was used as an experimental animal. When tumor cells are injected into the subiliac LN(SiLN) of this mouse, it has been known that the metastatic lesion is indced in the proper axillary LN which is a downstream LN of the SiLN. As a result of this study, the following was clarified; when drug administration rate to LN was fast, drug delivery to the downstream LN was not sufficiently done; anticancer agent-encapsulated liposomes having large particle size showed prolonged retention in the target LN; and drug delivery performance of anticancer drugs was improved by ultrasonic irradiation after injecting the anticancer agent-encapsulated liposomes into the metastatic LN.
