The expression level of COX7C associates with venous thromboembolism in colon cancer patients

Venous thromboembolism (VTE) is a common complication of colon cancer. In the present study, we aimed to explore the association of the oncogene COX7C to VTE in colon cancer patients. Samples from 580 patients were examined histologically for VTE and pathological characteristic of cancer. Gene mutation and expression analysis were performed using polymerase chain reaction-based assays to evaluate genes related to VTE, including COX7C. Univariate analysis between clinical pathological factors and VTE was conducted. Logistic regression analysis was performed for the prediction of VTE by pathological factors and gene expressions. Among patients investigated, a total of 56 patients had VTE. COX7C had a significant correlation with VTE (p < 0.001). Despite a correlation between tumor size, invasion depth of tumor, lymph node metastasis, lymph node metastasis, distant metastasis, lymphovascular invasion, histologic type and pathology type, Ki-67, and some other genes, to VTE (p > 0.05), only COX7C expression demonstrated significance in its ability to predict VTE. Here, we show that COX7C upregulation strongly correlates with VTE in colon cancer, which implicates its role as a biomarker and therapeutic target of VTE in colon cancer.
