研究目的:

我们拟通过本项目研究,明晰二甲双胍治疗肺腺癌脑转移瘤放疗患者神经认知功能障碍的疗效和安全性;了解二甲双胍对肺腺癌脑转移患者临床预后的影响;筛选出疗效相关的分子标志物,为肿瘤患者放疗后脑损伤神经的治疗策略提供新思路和试验依据。  

Objectives of Study:

Through this study, we intend to clarify the efficacy and safety of metformin in the treatment of neurocognitive dysfunction in patients with lung adenocarcinoma with brain metastases.To understand the effect of metformin on the clinical prognosis of patients with lung adenocarcinoma with brain metastases;Screening for molecular markers related to efficacy,so as to provide a new idea and experimental basis for the treatment strategy of brain injury nerve after radiotherapy for tumor patients.

药物成份或治疗方案详述:

将以上海交通大学医学院附属新华医院肺癌脑转移瘤放疗患者为研究对象,采用随机、双盲、安慰剂对照的临床研究方法,将入组病人分为颅脑放疗+二甲双胍组和颅脑放疗+安慰剂组。放疗前两周患者开始服用二甲双胍或安慰剂500mg qd,放疗开始时剂量增加至500mg tid,直至病情进展,或毒副作用无法忍受,或患者退出临床试验。放疗前、放疗后0-3个月、放疗后3-6个月、放疗后6-9个月分别进行白质和海马区MRI弥散峰度扫描(DKI)。每次MRI检查前采用MoCA量表对患者的认知功能进行评分。 

Description for medicine or protocol of treatment in detail:

Patients receiving radiotherapy for lung adenocarcinoma with brain metastases from Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine will be selected as study subjects ,using randomized, double-blind, placebo-controlled clinical study method. Enrolled patients are divided into the craniocerebral radiotherapy plus metformin group and the craniocerebral radiotherapy plus placebo group.Patients begin to take metformin or placebo 500 mg qd two weeks before radiotherapy. Than the dosage will increase to 500mg tid at the beginning of radiotherapy until the disease progresses, or the toxic and side effects become intolerable, or the patients withdraw from the clinical trial.During the study period, MRI diffusion-kurtosis imaging (DKI) will be used to scan the white matter and hippocampus regions before radiotherapy, 0-3 months after radiotherapy, 3-6 months after radiotherapy, and 6-9 months after radiotherapy. Meanwhiles, MoCA scale will be used to score the cognitive function for the patients before each MRI examination.

盲法:

采用两级盲法设计,第一级为两处理组所对应的代号(随机指定为A、B),第二级为各代号所对应的处理。两级盲底分别单独密封,全部处理编码所形成的盲底连同产生随机数的初值等参数,密封后各一式两份,分别存放于试验单位和统计单位两处妥善保存,试验期间,盲底不得拆阅。如果发生了任何非规定情况所致的盲底泄露,并影响了该试验结果的客观性,则该试验将被视作无效。

Blinding:

We designed a two-stage blind method,the first stage is the code corresponding to the two processing groups (randomly assigned as A and B), and the second stage is the processing corresponding to each code.The treatment code of the two stages shall be sealed separately. All parameters such as the treatment code formed by coding and the initial value of random number shall be processed in two copies after being sealed. The treatment code shall be properly stored in the test unit and the statistical unit respectively.The test shall be deemed invalid if there is any leakage of the blind bottom due to any non-specified circumstances which would affect the objectivity of the results of the test.
