title: [Clinical study of preoperative chemotherapy of primary breast cancer. 1. Efficacy of a combined use of CPA (endoxan) and FT-207 (or 5-FU dry syrup)].
abstract: In twenty-nine cases of primary breast cancer preoperative treatment using CPA and FT-207 (or 5-FUDS) was performed to determine their efficacy. Daily dose of each anticancer drugs was as follows: CPA 50-200 mg, FT-207 200-600 mg, 5-FUDS 200 mg, p.o.. The total doses were CPA 1.8 g, FT-207 5.0g, 5-FUDS 3.4 g in average. In 11 cases (37.9%) reduction in tumor size was obtained. According to Ohboshi's criteria, over Grade II a effect was seen in 5 cases (17.2%), while Grade III effect was not seen in any of the cases. Effective cases were more frequently observed among those which received CPA at 25 mg/kg or more, or FT-207 (5-FUDS) at 80 mg/kg or more. Main side effects were G. I tract symptoms such as anorexia and nausea. To obtain definitive conclusion on the clinical significance of use of CPA and FT-207 (5-FUDS) as preoperative chemotherapy for breast cancer, further studies are required.
