Abstract
There is controversy about the prognostic significance of occult lymph node metastases detected by immunohistochemistry with the anti-cytokeratin antibody CAM 5.2. The aim of this study was to characterize occult lymph node metastases in colorectal carcinomas that might be associated with a higher risk of recurrence. Three hundred fifty-eight lymph nodes from 10 recurrent and 9 nonrecurrent cases of colorectal carcinoma were examined. All these patients had been reported originally as having no lympho node metastases by routine hematoxylin and eosin staining. Three 10-μm sections or ten 3-μm sections (30-μm total thickness) from each lymph node were stained with CAM 5.2 and examined for the presence of occult lymph node metastases. Occult metastases were detected in 67 of 175 lymph nodes from the recurrent cases, and in 23 of 183 lymph nodes from the nonrecurrent cases. The frequency of positive nodes was significantly higher in the recurrent cases. The recurrent cases had metastases in nodes more distant from the main tumor than did the nonrecurrent cases. Detection of occult lymph node metastases with cytokeratin immunohistochemistry may make it possible to identify patients with a higher risk of recurrence after the removal of a primary colorectal tumor.
