As showed in Table 3, univariate analysis indicated that satellite nodules, microvascular invasion, CHK1-S in tumor tissue, the ratio of CHK1-S/L in tumor tissues and adjacent nontumor tissues were significantly associated with RFS of HCC patients, whereas other features, including age at diagnosis, gender, differentiation, cirrhosis, and envelope invasion, AFP, CHK1-L in tumor or adjacent normal tissue were not. The gene discussed is AFP; the disease is neoplasm.
