AFP and intrahepatic cholangiocarcinoma: Interestingly, although all of our patients were confirmed to have ICC by puncture pathology, the patients with higher AFP and HBV-DNA levels seemed to have a better response to TAI treatment than those with lower AFP and HBV-DNA levels, suggesting that in real-world clinical practice, a considerable proportion of ICCs confirmed by puncture pathology are actually mixed cell carcinomas; similarly, and the more HCC components, the better the response to TAI with the FOLFOX regimen will be.
