    Abstract:
    Blood samples from more than 1,000 patients with colorectal cancer were tested in the leukocyte migration test (LMT) and by a radioimmunoassay for carcinoembryonic antigen (CEA) for evaluation of: 1) the correlation of LMT response to the status of disease and 2) the use of LMT and CEA determination in the monitoring of patients after surgical removal of the primary tumor. A total of 320 patients, which were tested repeatedly, constituted the key group of the investigation: Of these, 56 patients developed recurrences or metastases whereas 217 patients showed no sign of reactivated disease. The group of patients with persistent absence of disease showed test profiles of either persistent negativity (50%) or conversion of one or both parameters; persistently positive profiles were rarely encountered. Patients with recurrences and metastases showed either positive profiles or conversion of positivity; only 3 patients were negative in both tests. However, despite significant disease-related response of the LMT, the test is not recommended as an adjunct to postsurgical monitoring, because of its technical complexity.
