[Bi-weekly chemotherapy with medium-dose docetaxel for advanced and recurrent breast cancers (The 15th study of Keiji Breast Cancer Study Group)].
The efficacy and safety of bi-weekly administration of medium-dose docetaxel (TXT) were evaluated in patients with advanced and recurrent breast cancers. The additional effect of 5'-DFUR for non-responders was also evaluated. Forty patients with advanced and recurrent breast cancers were treated and 38 cases of 40 were evaluated (34 with recurrent cases and 4 with advanced cases). All cases were female, and their mean age was 56.0 (38-74). TXT of 60 mg/body, which was equivalent to 30-50 mg/m2 for standard-sized Japanese women, was administered every two weeks. 5'-DFUR of 800 mg/body was added for non-responders after 5 weeks. The response rate was calculated from the data of 32 cases with measurable lesions, and side effects were evaluated in about 34 cases with exact records. Two hundred seventy-one courses were performed for 38 patients (4-24 courses per person, average 7.13 courses). The mean dosage per course of TXT was 58.4 mg/body (38.3 mg/ m2). Three complete and 7 partial responses were observed (overall response rate: 31.3%). Ten non-responders were evaluated for the additional effect of 5' DFUR, and one case reached PR. Grade 3/4 bone marrow suppression occurred in 9 patients, and Grade 3/4 general malaise was observed in two patient. According to the results, bi-weekly administration of medium dose TXT is an active and safe regimen in patients with advanced and recurrent breast cancers. The additional effect of 5'-DFUR was observed in one of 10 non-responders of bi-weekly chemotherapy with medium-dose TXT.
