[Clinical trial of fadrozole hydrochloride for postmenopausal patients with recurrent breast cancer].
Eleven recurrent postmenopausal breast cancer patients with osseous or lung metastases were received fadrozole hydrochloride at a dose of 1 mg twice a day for more than 8 weeks. The median disease-free interval of these 11 patients with metastasis was 74 months. Out of 11 evaluable cases, 2 PR, 6 long-NC and 3 PD were observed. The overall response rate was 18.2% and the long-NC rate was 54.5%. The average overall duration of responses and long-NC were 567 days and 573 days, respectively. There was no adverse drug reaction. A combination therapy with fadrozole hydrochloride 2 mg daily and cyclophosphamide 100 mg orally on days 1-14 was given to 14 postmenopausal patients with recurrent breast cancer. The median disease-free interval of these 14 patients with metastasis was 33 months. There were 2 CR, 3 PR, 4 long-NC, 2 NC and 3 PD. The overall response rate and long-NC rate were 35.8% and 28.6%, respectively. The average overall duration of responses and long-NC were 700 days and 443 days, respectively. The adverse drug reactions were anorexia (Grade 2) and neutropenia (Grade 1 and 2). These results suggested that a combination therapy with fadrozole hydrochloride and cyclophosphamide can be effective and contribute to survival time in the treatment of postmenopausal breast cancer.
