[Experimental study on the effect of UFT with concomitant radiotherapy of uterine cervical cancer]

In order to examine effectiveness of the chemotherapy with concomitant radiotherapy, an experimental study was designed using AMCC-1 cell line established from a human uterine cervical carcinoma in our laboratory. The growth of AMCC-1 cells cultured in plastic flask was inhibited significantly in the group treated with a half of minimal effective doses of 60Co and 5-FU in comparison with the control group. The 5-FU treatment after radiation inhibited the AMCC-1 cell growth more effectively than that before radiation. The growth of AMCC-1 tumor transplanted into nude mice was inhibited significantly in the group given a combination chemoradiotherapy, consisted of oral administration of three quarters of minimal effective dose of UFT for fourteen consecutive days and radiation of a half of minimal effective dose of 60Co. The oral administration of UFT after radiation inhibited the AMCC-1 tumor growth more effectively than that before radiation. These results suggest that the radiotherapy with administration of UFT was more effective against uterine cervical cancer than radiation alone and it is important to administer UFT orally after radiation as well as before radiation.
