    Abstract:
    BACKGROUND: The aim of this study is to diagnose the evaluation of concentration of CEA and TPS in postoperative monitoring of patients with colorectal cancer. PATIENTS AND METHODS: We measured 178 consecutive patients with histopathologically confirmed colorectal cancer: 101 men and 78 women ages 22-86 (average age 54.7). Markers' CEA nad TPS concentration were evaluated before operation and every month after operation during the first 3 months and then every 3 months during 2 years. Relapse was detected in 47 patients. RESULTS: In postoperative period in non-relapse group the mean (the average) concentration of CEA was 1.92+/-2.03 ng/ml and TPS 65.54+/-33.96 U/l and respectively in relapse group for CEA was 1.92+/-2.03 ng/ml and for TPS 65.54+/-33.96 U/l. The obtained results in investigated group show significantly statistical. The relapse was confirmed by using CEA concentration in 42 patients (89.4%). In case of TPS concentration relapse was confirmed in 38 patients (80.85%). The relapse was detected in 45 patients (95.74) if increase in CEA or TPS concentration was treated as a way of detecting relapse. TPS markers point out that the increase of TPS concentartion may be ahead of relapse symptoms at about 2-6 months. CONCLUSIONS: TPS is a useful marker in postoperative monitoring of patients with colorectal cancer. The evaluation of TPS concentration allow to diagnose the recurrence of colorectal cancer earlier than by using burden markers--CEA. Common evaluation of TPS and CEA increase sensitivity in detection of relapse in patients with colorectal cancer.
