Diagnosis and Staging

  • Stefano Cirillo
Part of the Updates in Surgery book series (UPDATESSURG)


Over the past several decades, the 5-year survival rates after resection of colorectal liver metastases have almost doubled, from about 30% to about 60%. Among other factors, this improved survival has been attributed to better preoperative imaging techniques, which have improved patient selection. In patients being considered for surgical therapy of hepatic colorectal metastases, a high-quality crosssectional imaging study, either contrast-enhanced CT or MRI, should be performed to evaluate these metastases before surgery. MRI, however, is inferior to CT in the evaluation of extrahepatic disease but superior in patients after preoperative chemotherapy. PET/CT appears to improve patient selection and should be considered as part of the preoperative evaluation of resectability in high-risk patients.
