The antitumor effect of hyperthermia combined with fluorouracil and its analogues.

The effectiveness of 5-fluorouracil (5-FU), FT-207 and FT-207 + uracil in combination with two repetitions of 43 degrees C hyperthermia in the treatment of the Meth-A-Fibrosarcoma and Sarcoma-180 was examined in vivo in BALB/c mice. The antitumor effect was evaluated in terms of inhibition of tumor growth by measuring the tumor for 7 days. The 5-FU concentration in each tumor was also monitored. Hyperthermia combined with FT-207 or FT-207 + uracil showed a synergistic effect for the inhibition of growth of both tumors which was not observed with 5-FU. There were no significant differences in the intratumoral concentration of 5-FU in unheated or heated Sarcoma-180 for any drug treatment after the first hyperthermia treatment, except for significant decreases in the group given 5-FU with the first hyperthermia treatment. After the second hyperthermia treatment, significant decreases in the concentration of 5-FU and FT-207 + uracil were observed. In the Meth-A-Fibrosarcoma, the intratumoral concentration of 5-FU decreased significantly in the group given 5-FU and increased significantly in the group given FT-207 + uracil after the first hyperthermia treatment, while there were significant decreases in 5-FU, FT-207 and FT-207 + uracil administered with the second hyperthermia treatment. Hyperthermia combined with FT-207 or FT-207 + uracil is considered to be effective.[1]
