Abstract:
A 60-year-old male undergoing pelvic evisceration with D3 lymph node dissection for pR0 in 2006f or carcinoma of the rectum was diagnosed pathologically with moderately differentiated adenocarcinoma, fStage ⅡA(UICC pT3, pN0, M0). Follow-up CT revealed hypovascular liver tumors with intrahepatic bile duct dilation in the right lobe 8 years after the pelvic evisceration. We conducted right lobe hepatectomy. The resected specimens showed that the tumor extended predominantly along the right intrahepatic bile duct. Histological findings and an immunohistochemical examination of CK7, CK20, and CDX2 revealed metastasis of the rectum cancer. We finally diagnosed him with intrahepatic bile duct metastasis from rectal adenocarcinoma.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
