Kit for predicting postoperative survival time of lung squamous carcinoma patient and application of kit

The invention discloses a kit for predicting postoperative survival time of a lung squamous carcinoma patient and application of the kit, and relates to the technical field of gene engineering. The kit comprises a reagent for detecting a target region, wherein the target region is selected from a non-coding region of a WDR74 gene. It is found that the WDR74 gene is a drive gene of lung squamous carcinoma, and based on the detection result of the mutation of the non-coding region of the WDR74 gene, the survival time of the lung squamous carcinoma patient after an operation can be predicted, auxiliary information is provided for the diagnosis and/or treatment of the lung squamous carcinoma patient, and the survival rate of the lung squamous carcinoma patient is improved. 本发明公开了一种预测肺鳞癌患者术后生存时间的试剂盒及其应用，涉及基因工程技术领域。该试剂盒包括用于检测目标区域的试剂；所述目标区域选自WDR74基因的非编码区。本发明的发明人发现，WDR74基因为肺鳞癌的驱动基因，基于对WDR74基因非编码区突变的检测结果，能够预测肺鳞癌患者手术后生存时间的长短，为肺鳞癌患者的诊断和/或治疗提供一种辅助性的信息，提高肺鳞癌患者生存率。
