The endocrine effects of 125 mg (low dose) aminoglutethimide (AG) twice daily (b.d.) were compared with those of 125 mg AG + 20 mg hydrocortisone (HC) b.d. in 23 and 45 postmenopausal patients with advanced breast cancer, respectively. The patients in each group were drawn from two separate populations, but the mean age and weight of the groups were similar and there were no significant differences between the pretreatment serum levels of the hormones investigated. Serum oestrone and oestradiol levels were suppressed by both treatments, but there was a significantly greater suppression by AG + HC. This greater suppression is probably due to the observed increase in serum androstenedione (i.e. precursor) levels with AG alone, whilst with AG + HC these levels were found to be reduced. In terms of suppression of serum oestrogen levels it is of benefit to combine low dose AG with HC.
分别对23例和45例绝经后晚期乳腺癌患者进行研究,比较每日两次服用125毫克(低剂量)氨鲁米特(AG)与每日两次服用125毫克AG加20毫克氢化可的松(HC)的内分泌效应。每组患者来自两个不同群体,但两组的平均年龄和体重相似,所研究激素的治疗前血清水平之间无显著差异。两种治疗均能抑制血清雌酮和雌二醇水平,但AG + HC的抑制作用明显更强。这种更强的抑制作用可能是由于单独使用AG时血清雄烯二酮(即前体)水平升高,而使用AG + HC时这些水平降低。就抑制血清雌激素水平而言,低剂量AG与HC联合使用有益。
