IL6 and hepatocellular carcinoma: For example, Öcal et al. (2021) reported a significant association between IL-6 and overall survival, even in multivariate analysis, while Carpizo et al. (2014) reported 22 patients (7 with HCC) after TARE with survival of more than 6 months who had lower baseline IL-8 levels but no correlation with IL-6.
