[Clinical trial on the effect of tegafur (SF-SP)]

SF-SP capsules containing sustained release granules of tegafur were orally administered 800 mg, b.i. d. for more than 4 weeks in 20 cases of advanced cancer, 11 of whom were evaluable (stomach 7, colon 1, liver 1, bile 1 and pancreas 1). The evaluation of antitumor effects was based on criteria of the Japan Society for Cancer Therapy, which are are almost the same as those of WHO. One partial remission out of 7 cases of stomach cancer was obtained, and its duration was 40 weeks. Toxicities were anorexia, nausea and vomiting, diarrhea and stomatitis, one case each of anorexia, and nausea and vomiting occurred within 10 days after SF-SP administration. No bone marrow depression, hepatic and renal disorders occurred after long-term SF-SP administration. SF-SP seems to be useful in the treatment of patients with gastric cancer.
