Integrative comparison of cHCC-ICC with hepatocellular carcinoma and intrahepatic cholangiocarcinoma revealed that combined and mixed type cHCC-ICCs are distinct subtypes with different clinical and molecular features. Integrating laser microdissection, cancer cell fraction analysis, and single nucleus sequencing, we revealed both mono- and multiclonal origins in the separate type cHCC-ICCs, whereas combined and mixed type cHCC-ICCs were all monoclonal origin. Notably, cHCC-ICCs showed significantly higher expression of Nestin, suggesting Nestin may serve as a biomarker for diagnosing cHCC-ICC. Our results provide important biological and clinical insights into cHCC-ICC.Graphical Abstract
Authors: Kreidieh M, Zeidan YH, Shamseddine A Abstract Treatment recommendations for primary liver malignancies, including hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), are complex and require a multidisciplinary approach. Despite surgical options that are potentially curative, options for nonsurgical candidates include systemic therapy, radiotherapy (RT), transarterial chemoembolization (TACE), and radiofrequency ablation (RFA). Stereotactic Body Radiation Therapy (SBRT) is now in routine use for the treatment of lung cancer, and there is growing evidence supporting its use in liver tumors. SBRT has...
Publication date: 10 June 2019Source: Cancer Cell, Volume 35, Issue 6Author(s): Marco Seehawer, Luana D’Artista, Lars ZenderPrognosis of combined hepatocellular carcinoma-intrahepatic cholangiocarcinoma, a type of primary liver cancer comprising areas with HCC and ICC histopathology, is dismal, and it is unclear if such tumors develop clonally and how they should be treated. In this issue of Cancer Cell, Xue et al. (2019) provide answers to these questions.
This article summarizes the milestones in the development of erdafitinib leading to this first approval for the treatment of urothelial carcinoma.
Conclusion: HBV promotes the aggressiveness of HCC in Chinese. Contributions of HBV to ICC and other etiological factors to HCC might be indirect via arousing non-resolving inflammation.

CONCLUSIONS: The landscape of DDR mutations and their association with genetic and clinicopathological features demonstrated that PLC patients with altered DDR genes may be rational candidates for precision oncology treatment. PMID: 31068370 [PubMed - as supplied by publisher]
Rationale: Wilson disease (WD) is an autosomal recessive hereditary disease in which the patient usually has a reduced risk of developing cancer. In particular, with the exception of hepatocellular carcinoma and cholangiocarcinoma, the incidence of cancer is significantly lower in WD patients compared with the general population. This case study presents a rare case of WD complicated with primary breast cancer. Patient concerns: A 40-year-old woman who was diagnosed with WD at 25 years of age found a lump in her left breast. She has a family history of cancer. Diagnoses: Ultrasound and mammography results were high...
