The authors have treated 15 patients with advanced gastrointestinal carcinoma with a cyclical regimen of combined Ftorafur (N/sub 1/-((2-furanidyl-))-5-Fluorouracil, a 5-FU pro-drug) and external beam radiation. The most common toxicity in general, and the most common limiting toxicity was nausea and vomiting, in contrast to oral FT alone where diarrhea is more prominent. Stomatitis was seen only once and no other form of serious toxicity was encountered. Two-thirds of the patients responded in subjective terms (pain relief). There was 1 partial response of FT alone (pulmonary metastases outside the treatment field). The sole patient whose treatment field was outside the abdomen (chest portals for esophageal carcinoma) developed pneumonitis which contributed to his death. No other delayed effects were noted. Serum FT levels were related to the infested dose and in the microgram range while serum 5-FU levels were in the nanogram range indicating slow decomposition of FT into 5-FU.
