AFP and cirrhosis of liver: The results showed that recurrence was correlated with CTC count (χ2=5.128P=0.024), tumor number (χ2=4.464, P=0.035), liver cirrhosis (χ2=11.559, P=0.001), Milan criteria (χ2=8.773, P=0.003), and University of California San Francisco (UCSF) criteria (χ2=10.225, P=0.001), while there were no significant differences in other groups like preoperative AFP (χ2=1.328, P=0.249).
