Aminoglutethimide 125 mg twice daily and hydrocortisone 20 mg twice daily was used to treat 76 postmenopausal women with advanced breast cancer. There were 4 CR, 17 PR (objective response rate 28%). Highest response was in soft tissue. CNS toxicity was less than with conventional dose AG (drowsiness 7% v. 31%), although the incidence of rash was equivalent. Previous responders to tamoxifen had a higher response (33%) than previous non-responders (9%). The lower toxicity and maintained efficacy suggest that this should be the standard dosage regimen.
