title: [Clinical study on the serum carcinoembryonic antigen, immunosuppressive acidic protein and C-reactive protein levels in patients with adult T cell leukemia].
abstract: Serum carcinoembryonic antigen (CEA), immunosuppressive acidic protein (IAP) and C-reactive protein (CRP) levels were measured in patients with adult T cell leukemia (ATL) in order to clarify their significance in this disease. Mean (+/- SD) serum CEA levels in 11 patients with acute ATL (3.1 +/- 1.3 ng/ml) and 7 patients with smoldering ATL (3.1 +/- 0.5 ng/ml) were significantly higher than in sera of 222 healthy controls (2.4 +/- 1.3 ng/ml). However, the levels in 7 patients with chronic ATL and healthy controls showed no differences. On the other hand, mean (+/- SD) serum IAP levels in patients with acute ATL (928 +/- 395 micrograms/ml), chronic ATL (487 +/- 125 micrograms/ml) and smoldering ATL (429 +/- 90 micrograms/ml) were significantly higher than in sera of healthy controls (359 +/- 103 micrograms/ml). However, the levels in patients with smoldering ATL and healthy controls showed no differences. Serum IAP levels in crisis in chronic and smoldering ATL were similar to those in patients with acute ATL. 85% of ATL patients with IAP levels above 500 micrograms/ml had CRP levels above 1+. Serum CEA, IAP and CRP levels were serially measured in a number of patients. Serum IAP and CRP levels reflected each patient's clinical course more than serum CEA levels. Overall the simultaneous measurements of serum CEA, IAP and CRP levels revealed a potential usefulness for determination of ATL subtype, and serum IAP and CRP levels may provide a way to evaluate the effectiveness of chemotherapy.
