The present study was performed to examine the possibility of intra-lymphatic chemotherapy with minimally invasiveness for cervical lymph node metastasis by using the lymph node metastasis mouse model showing lymphadenopathy. This study revealed that selective intra-lymphatic administration of anticancer agent is available. Moreover, it became clear that irradiation of ultrasonic waves after the simultaneous administration of nano-microbubbles and anticancer agent into the metastatic lymph node via lymphatic vessel enhanced effective induction of anticancer agent into the cells of the targeted lymph node.
