Moreover, Wang et al. revealed that the IL-11 has a chief role in postsurgical HCC recurrence; they also found that the IL-11/STAT3 signaling pathway promotes the proliferation of tumor cells and that the inhibition of IL-11/STAT3 signaling could reduce the postsurgical recurrence of HCC (Wang et al., 2019). Here, IL11 is linked to hepatocellular carcinoma.
