The liver is a unique organ where immunity can be biased toward ineffective response notably in the context of viral infections. Chronic viral hepatitis depends on the inability of the T-cell immune response to eradicate antigen. In the case of recombinant Adeno-Associated-Virus, used for therapeutic gene transfer, conflicting reports describe tolerance induction to different transgene products while other studies have shown conventional cytotoxic CD8 T cell responses with a rapid loss of transgene expression.

Current classification organizes these tumors into four molecular subgroups (WNT, SHH, Group 3, and Group 4 MB). Recently, a comprehensive classification has been established, identifying numerous subtypes, some of which exhibit a poor prognosis.

- Primary liver cancer can originate from two cell types, leading to different types of tumors: hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICCA), with combined tumors (cHCC-CCA) displaying mixed characteristics.
- Researchers utilized deep learning to categorize tumors in a study involving 405 cHCC-CCA patients, successfully distinguishing between HCC and ICCA types.
- This deep learning method showed potential for enhancing treatment strategies and improving patient outcomes for those with complex liver cancers.
Background & Aims: Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a rare primary liver cancer (PLC) associated with a poor prognosis. Given the challenges in its identification and its clinical implications, biomarkers are critically needed. We aimed to investigate the diagnostic and prognostic value of the immunohistochemical expression of Nestin, a progenitor cell marker, in a large multicentric series of PLCs.

Materials And Methods: Two centers prospectively included patients who underwent liver biopsy, B-mode ratio and CAP evaluation all on the same day between June 2017 and July 2019. MRI and histological morphometry were also performed in center 1.
