[The CEA test and other immunological tests as disease course controls in gastrointestinal adenocarcinoma].
161 patients with adenocarcinoma of the gastrointestinal tract were studied to determine the value of the CEA test and a battery of non-specific immunological tests during the course of the disease. The ability of these tests to detect a tumor recurrence in radically operated patients was evaluated. A false negative preoperative CEA value was found in 40% of the patients with gastric carcinoma and 32% with colorectal carcinoma. Patients with a negative preoperative CEA value, and those with only slightly elevated values, had a distinctly better prognosis regarding initial operability and tendency to postoperative recurrence than patients with primarily markedly elevated values. With few exceptions, the development of distant metastases was detected earlier and more easily with the CEA test than by the usual routine follow-up methods. However, in the event of isolated local recurrence the CEA test was positive in only 1 of 5 patients. This reflects the direct correlation between tumor size and CEA elevation. The CEA test is a valuable supplement in the follow-up of patients with gastrointestinal carcinoma.
