The aim of this study was to determine the cytomorphological characteristics of circulating tumor cells (CTCS) in patients with colo-rectal cancer and compare them with the primary tumor and metastasis. CTCS were obtained from blood using differential gel centrifugation and detected using standard immunocytochemistry using anti-CEA. Primary CTCs were defined as those detected before surgery and secondary CTCs those detected after. Surgical specimens of the primary tumor and metastasis were evaluated using standard histological methods with hematoxillin and eosin. CTCs both primary and secondary retained the cytomorphological characteristics of the primary tumor, showing marked intra-patient pleomorphism. There were no differences between primary and...
