Abstract
We are often faced with a situation in which a tumor has increased in size, as a result of a recurrence, despite repeated operations and radiotherapy (coupled with all kinds of chemotherapy and immunotherapy), and where all possibilities have been exhausted and no operation or cure is possible.
In order to try to maintain the quality of life with respect to the terminal stadium of oral carcinoma, we tried a chemotherapy method using a totally implanted one-shot intraarterial injection system via A. thyroidea superior and A. carotis externa. We are submitting a summary report as it may be of some help.
Compared with intraarterial injection methods based on non-implanted devices that have been used to date, this method offers many advantages-no risks of infection; no need to worry about such contingencies as the catheter being occluded or pulled out; and no imposition of extra restrictions regarding daily activities such as the taking of baths, and so on. Moreover, apart from intraarterial injection, it can be used for dropinstillation and repeating blood sampling such as that used for determining blood gas. It was possible to pursue the course of treatment with about one visit per week to the hospital.
