    Abstract:
    In order to use FT-207 rectum suppository for a long-term maintenance chemotherapy of squamous cell carcinoma of the uterine cervix, we examined its pharmacokinetics by single administration at a dose of 1 g employing chemical assay. The results were as follows: 1. The blood level of FT-207 showed its peak of 30 mcg/ml at 2 hours after administration, of which half-time was 9 hours. Inter-individual differences were few in changes in the curve. 2. The blood level of 5-FU showed two peaks, 0.25 mcg/ml at 4 hours and 0.017 mcg/ml at 36 hours after administration. There were large inter-individual differences in its alteration. 3. At the time of operation, both FT-207 and 5-FU showed low concentrations in blood. 4. The level of 5-FU in cervical focus was 0.068 mcg/g which was the highest among those in all genital organs, and 2.7 times higher than the level of 5-FU in blood. 5. There was a significantly positive correlation at r = 0.174 (p less than 0.1) between the level of 5-FU in the focus of cervical cancer and the level of FT-207 in blood.
