title: Influence of mastectomy technique on sex steroid receptor analysis.
abstract: Accurate analysis of hormone receptors in breast carcinoma is critical from prognostic and therapeutic standpoints. Controversy exists over whether there is receptor decay when specimens are obtained upon completion of, rather than prior to, mastectomy. In addition, the effect of mastectomy technique on receptor concentration has not been addressed. Twenty patients with breast carcinoma had biopsy specimens taken prior to and upon completion of modified radical mastectomy. Ten had axillary dissection followed by mastectomy (Group A). The others had mobilization of the breast before axillary dissection (Group B). The estrogen receptor concentration was higher in 14 of 20 premastectomy specimens. All 10 patients in Group B had positive receptors before mastectomy; 5 were negative after mastectomy. All seven patients in Group A with positive premastectomy receptors remained so postmastectomy. We concluded that if a tumor specimen for receptor analysis is not obtained prior to modified radical mastectomy, axillary dissection should precede breast mobilization.
