Circulating Th17 and Th1 cells, and their ratio were associated with survival in HCC.

<p>(<b>A and B</b>)Patients with high levels of circulating Th17 cells had significantly shorter OS and DFS than those with low levels. (<b>C and D</b>)Patients with high levels of circulating Th1 cells had significantly longer OS and DFS than those with low levels. (<b>E and F</b>)Kaplan-Meier curves reveal a significant difference in the cumulative recurrence and survival rates of patients with different Th17/Th1 ratios. The patients with high Th17/Th1 ratios had significantly shorter OS and DFS than those with low Th17/Th1 ratios.
