To further investigate the significance of PCDHGA9 in colorectal cancer, we collected clinicopathological information of CRC patients, which was then assessed in combination with PCDHGA9 expression, particularly in regards to patient age, gender, tumor location, tumor size, tumor stage, tumor differentiation, tumor invasion degree, and lymphatic vascular metastasis. This evidence concerns the gene PCDHGA9 and colorectal carcinoma.
