【摘要】　目的　探讨老年性乳腺癌术前内分泌治疗效果及降期后手术优点。　方法　 2004年5月－2010年12月19例老年性局部晚期乳腺癌患者，术前给予口服芳香化酶抑制剂（aromatase inhibitors，AI）2～10个月，进行疗效观察，降期后手术及术后同一有效内分泌药物继续治疗并随访，时间1～66个月。　结果　自AI治疗开始至手术时，临床完全缓解2例，部分缓解11例，稳定3例，进展3例；手术14例，另5例由于全身状况差、基础疾病严重不能耐受手术或局部进展而放弃手术，5年总生存率68%，无瘤生存率47%。　结论　术前内分泌治疗疗效可靠，不良反应轻，特别适应老年伴有内科疾病不适应化学疗法的患者，可以增加保乳手术率和手术切除率。
【Abstract】　Objective　 To investigate the clinical value of neo-adjuvant endocrine therapy for locally advanced breast cancer in elderly patients and the advantages of operation after down-staging of breast cancer.　Methods　 From May 2004 to December 2010, 19 patients with locally advanced breast cancer were treated with Aromatase inhibitor (AI) neo-adjuvant endocrine therapy for 2 to 10 months before operation. The clinical efficacy was observed. Operation was performed after down-staging of the cancer. After the operation, patients continued taking the same effective drug and were followed-up for 1 to 66 months.　Results　 From AI treatment to the time of operation, there were 2 cases of clinical complete response, 11 cases of clinical partial response, 3 cases of stable disease, and 3 cases of progressive disease. A total of 14 patients were operated, and 5 other patients could not have the operation for bad body conditions, serious basic-diseases or local progress of the disease. The 5-year overall survival rate was 68%, and the disease-free survival rate was 47%.　Conclusion　 Neo-adjuvant endocrine therapy has a reliable clinical effect and low side-effects. It is especially suitable for elderly patients excluded from chemotherapy because of internal medical diseases. It can also increase the rate of breast-conserving and surgical excision.
