The combined effects of X-ray irradiation and 5-FU derivatives (5-FU, tegafur, HCFU) treatment were investigated in mouse adenocarcinoma-755. Mice were given a single irradiation 5 Gy or 10 Gy of 6-MV X-rays and orally administered 5-FU derivatives at the time of pre- or post-irradiation. Under these conditions, antitumor activity and survival time were compared between pre- and post-irradiation. Under these conditions, antitumor activity and survival time were compared between pre- and post-irradiation, in combination with 5-FU, tegafur or HCFU. The antitumor effects and survival time were greater for pre-irradiation treatment than for post-irradiation. Among 5-FU derivatives, the highest combination effect was shown by HCFU, followed by 5-FU and tegafur. The concentration of 5-FU in the tumor was correlated with the antitumor effect of each drug.
