Objective: To investigate the expression of cell proliferating nuclear antigen (Ki67) and cytokeratin 19 (Ck19) in hepatocellular carcinoma (HCC), and correlation with the clinicopathological features and apparent diffusion coefficient (ADC) value of hepatocellular carcinoma. Methods: The data of 203 newly diagnosed HCC patients in the Affiliated Cancer Hospital of Zhengzhou University from January 2014 to October 2019 were retrospectively collected, and the expression of Ki67 and Ck19 and ADC values in all patients were analyzed. The relationship between Ki67 and Ck19 and the clinical pathological characteristics of the patient, and calculate the difference and correlation with the ADC value was analyzed. Results: There were statistically significant differences in tumor vascular tumor thrombus, alpha-fetoprotein (AFP), postoperative tumor recurrence, lymph node metastasis, and HCC differentiation between Ki67 positive and negative groups (χ²=5.156, 12.741, 29.925, 3.963, 77.408, all P<0.05),and negatively correlated with ADC value (r=-0.214, P=0.002). The average ADC value of HCC in the low Ki67 group was significantly higher than that of the high Ki67 group (1 089±280 vs 1 009±212, P<0.05). There were statistically significant differences in tumor vascular tumor thrombus, AFP, postoperative tumor recurrence, and lymph node metastasis between Ck19 positive and negative groups (χ²=9.058, 27.034, 4.053, 14.187, all P<0.05), but not correlated with ADC value (r=0.062, P=0.380). The expression differences of Ki67 and Ck19 in different HCC recurrence time groups were statistically significant (P<0.05). Conclusion: The positive expression of Ki67 and Ck19 in HCC was associated with the prognosis and recurrence of HCC. CK19 was not correlated with the ADC value, while Ki67 was negatively correlated with the ADC value, indicating that ADC value could provide certain imaging information for the biological characteristics of preoperative HCC.
