Postchemotherapy histological analysis of major intrahepatic vessels for reversal of attachment or invasion by colorectal liver metastases

Although tumor reduction via present‐day prehepatectomy chemotherapy can render initially unresectable disease potentially resectable, little is known about the effects of such chemotherapy on liver metastases with known attachment to or invasion of major intrahepatic vessels. We histologically assessed the relationships of liver tumors to major intrahepatic vessels after chemotherapy.
