I. Chemotherapy

Sullivan and associates (1959) reported new tech-nique of continuous, long-term arterial infusion of an antimetabolite to the patients with advanced can-cer in conjunction with the systemic administra-tion of its metabolite antagonist to prevent general toxicities and potential usefulness in this new meth-od has been reported by many authors.

In the past few years, we also tried intra-arterial regional infusion in 11 instances for the treatment of patients with advanced brain tumor (s). One of the drugs commonly used was methotrexate. FUdR and Nitrogen Mustard were also used for several cases.

Results were far more unsatisfactory. Seven cas-es out of these 11, died soon after chemotherapy without showing any noticeable improvement and definite palliation attributable to this therapy could not be obtained in any case. However, it is too early to evaluate the benefits of this kind of infusion therapy. Most of patients we treated were at or near the terminal stage and they developed severe systemic reactions despite ussage of the massive doses of antidote. Consequently, in most instances, it was unable to give full closes of anticancer agents. Better results might be expected if we treat patients at earlier stage and infusion can be continued for more prolonged period in the range of months rather than weeks.

II. Radiation Therapy

Results of 285 cases of brain tumors treated with radiation in our series of 1955-1964 were present-ed.

In the group of glioblastoma, results indicated that radiation following surgery may expect a mu-ch longer longevity.

In the cases of chromophobe adenoma, more re-markable improvement of visual function could be obtained in the group treated with surgery and subsequent irradiation as compared with that treat-ed with surgery alone. In view of this it would be incorrect to assume that radiation therapy alone is necessarily of equal effectiveness to combination therapy. Comparing the results obtained between the group treated with estimated tumor doses of more than and less than 6000R, more favorable results were noticed in the latter group.
