将下面句子转换为英文：先是针对几个大型数据库筛选出对ECM和药物靶点敏感的基因然后使用Cox回归构建风险模型优选出6个与DDFS相关的DEDREGs。后用临床数据和题目对模型进行评估接着分析与免疫环境、肿瘤微环境和药物微环境的相关性。最后展示实验过程的结果评价分险模型然而该文章还存在部分问题需要作修改后再次提交。

First, genes sensitive to ECM and drug targets were selected from several large databases. Then, Cox regression was used to construct a risk model, and 6 DEDREGs related to DDFS were selected. The model was evaluated using clinical data and the topic, followed by an analysis of the correlation with immune environment, tumor microenvironment, and drug microenvironment. Finally, the results of the experimental process were presented, and the risk model was evaluated. However, there are some issues in this article that need to be revised before resubmission
