[Effectiveness of LH-RH agonist for bone metastases of breast cancer--report of a case].

A 44-year-old premenopausal woman with bone metastases of breast cancer was initially treated with systemic chemotherapy (CEF) and radiation therapy after standard mastectomy. However, progressive change of bone metastases with elevation of tumor markers (CEA, NCC-ST 439) was detected, so continuous administration of LH-RH agonist and combination chemotherapy (CEF) were conducted. Subsequently, complete objective regression was attained after 40 weeks.
