研究目的:

为验证二甲双胍在乳腺癌合并糖尿病前期患者新辅助化疗中的抗癌作用,我们拟开展一项全国多中心、随机、双盲、安慰剂对照研究,研究分为四个步骤,其目的分别为: 1、 筛选BPD人群:在拟行新辅助化疗的乳癌患者中,利用口服葡萄糖耐量(OGTT)+胰岛素释放试验,检测胰岛β细胞功能、胰岛素抵抗的状况。 2、 二甲双胍抗癌作用:符合新辅助化疗治疗指征、伴有糖尿病前期[空腹血糖受损(IFG)、糖耐量异常(IGT)]的乳癌患者,随机分为2组:第1组接受安慰剂治疗,第2组接受二甲双胍(格华止)850mg 一日两次治疗。主要终点为新辅助化疗结束后两组间pCR率是否有差异。 3、 二甲双胍抗癌作用与胰岛素敏感性的关系:新辅助化疗结束后,进行OGTT+胰岛素释放试验,观察二甲双胍抗癌作用是否与胰岛素敏感性的改善有关。 4、 继续随访,观察其它次要终点: (1) 糖脂代谢方面:糖尿病发生情况(每年行1次OGTT,观察糖尿病发生情况),糖尿病并发症及合并症发生情况(3-5年)。 (2) 肿瘤方面:Ki-67等指标(新辅助化疗结束后),乳癌事件及全因死亡率(5-10年)。  

Objectives of Study:

In order to identify the effect of metformin in the breast cancer patients with prediabetes during neoadjuvant chemotherapy, we are going to conduct a nationwide multicenterrandomizeddouble blindplacebo control clinical study, it includes four major steps: 1. Screening for prediabetes patients: Administer OGTT and insulin releasing test to identify the status of pancreatic β cell function and insulin resistance in breast cancer patients who are planning to take neoadjuvant chemotherapy; 2. Anti-cancer effect of metformin: Conform to the indications of neoadjuvant chemotherapy and coexistence of prediabetes [impaired fasting glucose(IFG)impaired glucose tolerance(IGT)] in breast cancer patients, and randomize in two groups: group 1 will receive placebo treatment, group 2 will receive metformin 850mg bid. The primary endpoint is PCR rate in two groups after finish neoadjuvant chemotherapy; 3. Relationship between anti-cancer effect of metformin and insulin sensitivity: After finish neoadjuvant chemotherapy, administer OGTT and insulin releasing test again and identify whether the anti-cancer effect of metformin is associate with insulin sensitivity improved; 4. Follow up and confirm secondly endpoints: (1) Glucolipid metabolism: The prevalence of diabetes(administer OGTT once per year and identify the prevalence of diabetes) and diabetic complications(3 to 5 years); (2)Oncological:Breast cancer events (3 to 5 years).
