Title: [2d and 3d line hormonal therapy in postmenopausal metastatic breast tumor. Comparison of medroxyprogesterone acetate and aminoglutethimide in tamoxifen-resistant patients]. Author: Garcia-Giralt E, Omodei Zorini C, Ferri L, Ayme Y, Carton M, Daban A, Delozier T, Fargeot P, Fumoleau P, Gorins A. Journal: Clin Ter; 1994 Aug; 145(8):113-21. PubMed ID: 7955956. Abstract: In order to evaluate the effectiveness of second and third line hormone therapy for postmenopausal (spontaneous or surgical) women with metastatic tamoxifen-resistant breast cancer, 293 women aged 36 to 91 (mean 63.6) were divided into two groups submitted to a multicenter study of two treatment schedules: a) Aminoglutethimide (AG; 500 mg daily plus hydrocortisone 40 mg daily); b) Medroxyprogesterone (MPA; 1,000 mg daily per os). Of the 293 patients receiving second line hormone therapy, only 161 were available for third line treatment. In phase 1, 153 patients were treated with AG: 36% had objective responses (complete or partial); of 140 patient receiving MPA, 33% had objective responses (p = 0.045, significant). In the AG-treated group, duration of response was 11.3 +/- 8.4 months as against 8.3 +/- 5.6 months in the MPA group (p = 0.07, significant). In phase 2, 87 women previously treated with MPA received AG, and 74 previously AG-treated patients were given MPA. There were no significant differences in the results obtained. In conclusion, there were no significant differences in the results obtained by AG and MPA treatment as far as toxicity and survival was concerned but there was a statistically significant advantage for AG as second and third line management both as to objective responses and mean time until renewed progression of the disease.[Abstract] [Full Text] [Related] [New Search]
