A 65-year-old man presents with new liver lesions on surveillance imaging 2 years after a right hemicolectomy for cecal adenocarcinoma. The primary tumor was pT3N1, microsatellite stable, and KRAS wild type. He completed adjuvant FOLFOX. His CEA level is 22 ng/mL. There are two 1.5-cm lesions in the right lobe near the dome of the liver and a 4-cm lesion in segment II. No luminal recurrence is detected endoscopically, and there is no evidence of peritoneal or pulmonary disease.
