Correlations of CTC number and PCP with HCC prognosis‐related clinical parameters. (A) The scatter plots show the comparison of preoperative CTC numbers under different clinical stratification criteria, including single or multiple tumors, tumor diameter, MVI, thrombosis, AJCC stage, and BCLC stage. (B) The scatter plots show the comparison of preoperative PCP under different clinical stratification criteria, including single or multiple tumors, tumor diameter, MVI, thrombosis, AJCC stage, and BCLC stage (Mann–Whitney t test, two‐tailed and one‐way ANOVA test). AJCC, American Joint Committee on Cancer; BCLC, Barcelona Clinic Liver Cancer stage; CTC, circulating tumor cell; MVI, microvascular invasion; PCP, proliferative CTC percentage.
