[A case of uterine cervical cancer in which UFT was an effective preoperative treatment]

We report a case in which UFT was effective as a preoperative treatment for stage II b cervical cancer. The patient was a 66-year-old female whose chief complaint was brown vaginal discharge. Following cytological, histological and CT examinations, a diagnosis was made of papillary squamous cell carcinoma invading the vagina and left parametrium. We administered UFT (600 mg/day, for 5 days) as one course, and conducted two courses with an interval of 2 days. The tumor had shrunk 2 weeks later and a radical hysterectomy was performed after additional treatment with intraarterial cisplatin (120 mg/body) infusion. Thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD), which are enzymes in 5-FU metabolism, and the labeling index (ID) of DNA fragmentation in the tumor were estimated before and after UFT. The results showed that TS was 0.69 pmol/g tissue and DPD 39.98 pmol/mg/min before UFT, and that LI of DNA fragmentation was 21.8 +/- 5.0% before UFT and 37.9 +/- 16.2% after UFT. We suggest that preoperative UFT administration is an effective treatment for cervical cancer, and that TS, DPD and LI of DNA fragmentation might be useful biomarkers to estimate the sensitivity of UFT.
