422, 95%CI = 1.183–3.273, P = 0.031), p-TNM Stage (HR = 1.752, 95% CI = 1.312–2.437, P = 0.042) and high expression of PRC1 protein (HR = 2.391, 95% CI = 1.528–2.908, P = 0.024) were independent prognostic factors for adenocarcinoma patients (Fig. 2c). This evidence concerns the gene PRC1 and adenocarcinoma.
