Tumor marker for Ca colon for follow up
Correct Answer: CEA
Description: Up to a half of all patients with colorectal cancer will develop liver metastases at some point and regular imaging of the liver (by ultrasound and CT scan) and measurement of carcinoembryonic antigen (CEA) is designed to diagnose this early, in order to allow curative metastectomy. Trials of the optimum follow-up pathway have suggested that CEA measurement alone can be as effective as regular imaging.Ref: Bailey and Love, 27e, page: 1266
