[Fundamental studies on the introduction of chemotherapy of uterine cervical carcinoma--tissue level of 5-FU after oral administration].
In Japan, oral 5-FU has been popularly used as an adjuvant chemotherapy to surgical operation mainly gastrointestinal carcinomas. This drug is generally administered consecutively at a low dose over a long term, because of its distribution at high levels in the upper gastrointestinal organs after oral administration. The authors have attempted to introduce the oral administration of 5-FU as an adjuvant chemotherapy in the treatment of uterine cervical carcinoma, and the results of a preliminary trial are reported in this paper; that is, the 5-FU level in target organs was measured after oral administration of 5-FU in 44 cases of uterine cervical carcinoma. Judging from the 5-FU level in organs removed about 2 hours after preoperative administration of 5-FU at 300 mg, the distribution of the drug to bilateral lymph nodes and the uterine cervix was good, and when calculated on the basis of the trace as 0, the average tissue level was 0.0432 microgram/g in the left lymph node, 0.0104 microgram/g in the right lymph node and 0.0190 microgram/g in the uterine cervix. From the above, it was concluded that, in the application of oral 5-FU as an adjuvant chemotherapy to treatment of uterine cervical carcinoma, a different manner application procedure should be established from that used to treat gastrointestinal carcinoma; that is, 5-FU should be administered intermittently at a moderate dose.
