Further, HCC expression of PCNAP1 was related to TNM clinical stage, lymph node metastasis, and maximum tumor diameter (χ2 = 10.337, 6.718, and 8.164; P < 0.05), but not related to gender or age (χ2 = 6.228 and 5.309; P = 0.459 and 0.656) (Table 1). This evidence concerns the gene PCNAP1 and hepatocellular carcinoma.
