A phase I clinical study of intravenous Tegafur was conducted in nineteen previously treated patients with primary lung cancer. The dose of Tegafur was elevated from 1.0 to 3.0 g/m2/day for five consecutive days to determine the maximum tolerated dose. The dose-limiting factors were gastrointestinal and neurological toxicity and fatigability observed with the dose level of 2.5 g/m2/day for 5 days. Hematologic, hepatic and renal toxicities were not observed. Gastrointestinal toxicity including nausea, vomiting, anorexia and diarrhea of over grade 2 were seen to result from the dose of 2.5 g/m2/day. Neurological toxicity consisted of headache, dizziness, anxiety and depression. At the dose level of 2.0 g/m2/day, one patient, who had epileptic seizures in the past, experienced a psychomotor seizure. Depression (Grade 2 CNS toxicity) was observed at the dose level of 3.0 g/m2/day. Dose limiting factors were neurological toxicities. The pharmacokinetics of tegafur and 5-FU (the active form of Tegafur) has been studied in all patients. Serum level of tegafur was measured by HPLC method, and serum level of 5-FU was analyzed by GC-MS method. At the dose level greater than 2.0 g/m2/day for 5 days, the mean serum 5-FU values appear over the therapeutic range (0.1 micrograms/ml). In conclusion, 2.5 g/m2/day for 5 days was considered to be MTD, and 2.0 g/m2/day for 5 days intravenous administration was recommended for the phase II trial of single agent chemotherapy.

A phase I clinical study of tegafur (ftorafur) was conducted in 29 patients with various advanced solid tumors. To evaluate its efficacy and toxicity, the initial dose of 0.5 g/m2/day x 21 days at 3-week intervals was progressively increased to a maximum dose of 1.5 g/m2/day. Tegafur was administered orally in two or three divided doses. Diarrhea was the dose-limiting toxic effect and occurred more often in patients with abnormal pretreatment liver function. Nausea occurred in about one-half of the patients, but vomiting was infrequent. Skin rash and mucositis occurred in 10% and 7% of the patients, respectively. Neurologic toxic effects of tegafur were infrequent and mild. The hematologic toxicity of tegafur was minimal. Antitumor activity could be evaluated in 21 patients with measurable disease. One complete and three partial responses were observed in four of 17 patients who had adenocarcinoma of unknown primary origin. All responses occurred at doses greater tan or equal to 1.0 g/m2/day. The recommended dose of tegafur for this schedule of administration is 1.0 g/m2/day.

Thermotherapy combined with Tegafur and Picibanil was performed in 32 patients with cancer of the urinary bladder. The thermotherapy was performed with a closed circulation type of thermotherapeutic apparatus manufactured for trial, using a 3-way catheter. The flow quantity of the perfusate was 150 ml/min at a constant temperature of 43 degrees C. The temperature was monitored at the inlet and outlet catheter at the urethral meatus. The thermotherapy was performed for 6 hours once a week. Tegafur and Picibanil were added to the perfusate at the time of thermotherapy. No anesthesia was used. Complete disappearance of tumor occurred in 9 cases. The concentration of Tegafur in the serum, tumor and bladder wall was simultaneously measured. The serum levels after two hours of thermotherapy with 16 gm of dissolved Tegafur showed that FT-207 was 28.837 mcg/ml and 5-FU, 0.028 mcg/ml. After 4 hours the FT-207 was 36.464 mcg/ml and 5-FU, 0.040 mcg/ml. By the 6th hour FT-207 was 39.430 mcg/ml and 5-FU, 0.049 mcg/ml. After 24 hours FT-207 was 11.242 mcg/ml and 5-FU, 0.013 mcg/ml in the serum, while FT-207 was 8.205 mcg/g and 5-FU, 0.274 mcg/g in the bladder tumor, and FT-207 was 17.029 mcg/g and 5-FU, 0.157 mcg/g in the bladder wall. Nausea was observed in 1 case in which a large quantity of Tegafur was absorbed. No other side effects were noted.

A 47-year-old man with ascending colon cancer with multiple liver metastases and bone metastasis (VII thoracic vertebra) showed a remarkable response to the combination therapy of tegafur and cisplatin. Tegafur (1,200 mg/day) was administered through continuous intravenous infusion mixed with IVH, and cisplatin was given every two weeks at a dose of 100 mg. The total dose of tegafur was 39.6g and that of cisplatin was 300mg. After therapy, primary and metastatic lesions were remarkably reduced according to various imaging techniques, and the serum CEA level of 34ng/ml at diagnosis decreased 3.7 ng/ml. Various tumor-related symptoms were improved. Drug toxicity caused slight nausea and leucopenia. Right hemicolectomy with R2 lymph node dissection was performed after chemotherapy. Histologically, primary lesion and regional lymph nodes showed diffuse fibrosis and necrosis, and only a few cancer cells remained some vessels. These results suggested that the combination chemotherapy of tegafur and cisplatin is useful for the treatment of colon cancer.

Tegafur is a prodrug of the antineoplastic agent fluorouracil, and is administered in a 1:4 molar ratio with the fluorouracil modulator uracil. Oral tegafur/uracil 300 mg/m(2)/day plus calcium folinate 75 or 90 mg/day for 28 days every 35 days was as effective as intravenous (IV) fluorouracil 425 mg/m(2)/day plus folinic acid 20 mg/m(2)/day for 5 days every 28 or 35 days in the treatment of patients with metastatic colorectal cancer in two large, randomised, nonblind, multicentre trials (n = 816 and 380). Median survival time among patients treated with tegafur/ uracil or fluorouracil was approximately 12 months in both trials. Results from both trials also demonstrated no significant between-group differences in overall response rates among patients treated with oral tegafur/uracil (12 and 11%) or IV fluorouracil (15 and 9%). In elderly patients (aged > or = 70 years) with metastatic colorectal cancer, results from small noncomparative studies showed that treatment with oral tegafur/uracil afforded overall response rates of 12.5 to 29% and was well tolerated. During preoperative treatment with oral tegafur/uracil plus calcium folinate as an adjunct to radiotherapy in patients with stage II or III rectal cancer, the maximum tolerated dosage of tegafur/uracil was 350 mg/m(2)/day (administered 5 days per week for 5 weeks). Among the 15 patients who were followed for 5 to 8 months, three had a complete response to treatment. Treatment with tegafur/uracil was also given postoperatively. The most common adverse events associated with oral tegafur/uracil were anaemia, nausea/vomiting, diarrhoea, thrombocytopenia, mucositis, neutropenia, asthenia, anorexia and abdominal pain. Oral tegafur/uracil was associated with a significantly more favourable tolerability profile than IV fluorouracil in the two large randomised trials. In particular, stomatitis and most adverse haematological events were less frequent.

The purpose of this study was to evaluate the efficacy, assessed as response rate, and toxicity of UFT (Tegafur-Uracil) in combination with oxaliplatin as first-line treatment of advanced colorectal cancer (CRC). In all, 84 patients with recurrent or metastatic CRC with measurable disease were included. Treatment consisted of oxaliplatin 85 mg m(-2) in 120-min intravenous (i.v.) infusion on days 1 and 15; i.v. l,leucovorin (l,LV) 250 mg m(-2) given in 2 h on day 1, followed by oral UFT 390 mg m(-2) on days 1-14, and oral l,LV 7.5 mg/12 h on days 2-14. Cycles were repeated every 28 days. A total of 492 cycles of chemotherapy were delivered with a median of six per patient (range 1-12). There was one complete response (1%) and 28 partial responses (34%) for an overall response rate of 35% (95% confidence interval (CI): 24-46%). A total of 36 patients (44%) had stable disease, whereas 17 (21%) had a progression. The median time to progression was 7.3 months and the median overall survival was 16.8 months. A prescheduled preliminary analysis was performed after inclusion of 16 patients who detected a high gastrointestinal toxicity, which led to a reduction of the UFT dose to 300 mg m(-2). With this new dosage, grade 3-4 diarrhoea and grade 3-4 nausea/vomiting dropped to 21 and 14% of patients, respectively. Other grade 3-4 toxicities were stomatitis in one (1%), anaemia in three (5%), neutropenia in two (3%), thrombocytopenia in one(1%), fatigue in six (9%), peripheral sensory neuropathy in nine (14%) and laryngopharyngeal dysesthesia in two patients (2%). The combination of oxaliplatin and UFT-l,LV is an active, easy-to-administer regimen with moderate toxicity. Hence, this regimen is worthy of further investigation.

To evaluate ambulatory patient cancer chemotherapy, the clinical response, toxicities and survival time were analysed among 19 patients with non-curative or recurrent colorectal cancer who were treated by Uracil/Tegafur (UFT) plus oral Leucovorin (UZEL) for the past 2 years. The patients were administered UFT (300 mg/m2/day) and UZEL (75 mg/body/day) for 28 days with a one-week interval every 35 days as one course.A partial response (PR) was observed in 6 patients (31.6%) and stable disease (SD) in 8. The median survival time was 16 months. Although nausea/vomiting, diarrhea and leucopenia were noted, no severe side effects were observed. These results suggested that UFT plus Leucovorin therapy might be a useful cancer chemotherapy for ambulatory patients with advanced colorectal cancer.
