[The effect of combined chemotherapy with UFT, cis-platinum and aclarubicin in metastatic brain tumors].

Thirteen patients with metastatic brain tumors were treated with two different chemotherapy regimens. Six patients were treated with three antitumor drugs, UFT, CDDP and ACR (Group A) and the other seven patients were treated with two antitumor drugs, CDDP and ACR (Group B). Initial response to each therapy was compared with the changes in tumor size on CT scan and clinical state before and after treatment. Five cases in Group A demonstrated complete remission and one case revealed partial response on CT scan. The residual tumor on CT scan at one month in one case of partial response also completely disappeared after three months. It was thought that there might have been an effect of UFT in this case. Four cases in Group B showed complete remission and three cases revealed partial response on CT scan. However, the CT findings in the three cases of partial response were unchanged on follow-up CT scan. Clinical state evaluated by Karnofsky scale did not deteriorate in Group A, while three cases showed a deteriorated Karnofsky scale in Group B. As side effects, there were mild myelosuppression, nausea and vomiting in both Groups, which did not persist for a long time. The cause of death in both Groups was mainly recurrence of the primary lesion or metastasis to other organs. It was thought that the effect in Group A was better than that in Group B as a result of these findings. The tissue concentration of ACR was measured in six patients, and the mean value was 0.558 micrograms/g at 15 min. This concentration was thought high enough to kill tumor cells.
