Applicative Value of Serum CA19-9, CEA,CA125 and CA242 in Diagnosis and Prognosis for Patients with Pancreatic Cancer Treated by Concurrent Chemoradiotherapy

Objective: To evaluate the application value of serum CA19-9, CEA, CA125 and CA242 in diagnosis andprognosis of pancreatic cancer cases treated with concurrent chemotherapy. Materials and Methods: 52patients with pancreatic cancer, 40 with benign pancreatic diseases and 40 healthy people were selected. Theelectrochemiluminescence immunoassay method was used for detecting levels of CA19-9, CEA and CA125, anda CanAg CA242 enzyme linked immunoassay kit for assessing the level of CA242. The Kaplan-Meier methodwas used for analyzing the prognostic factors of patients with pancreatic cancer. The Cox proportional hazardmodel was applied for analyzing the hazard ratio (HR) and 95% confidential interval (CI) for survival timeof patients with pancreatic cancer. Results: The levels of serum CA19-9, CEA, CA125 and CA242 in patientswith pancreatic cancer were significantly higher than those in patients with benign pancreatic diseases andhealthy people (P<0.001). The sensitivity of CA19-9 was the highest among these, followed by CA242, CA125and CEA. The specificity of CA242 is the highest, followed by CA125, CEA and CA19-9. The sensitivity andspecificity of joint detection of serum CA19-9, CEA, CA125and CA242 were 90.4% and 93.8%, obviouslyhigher than single detection of those markers in diagnosis of pancreatic cancer. The median survival time of52 patients with pancreatic cancer was 10 months (95% CI7.389~12.611).. Patients with the increasing level ofserum CA19-9, CEA, CA125, CA242 had shorter survival times (P=0.047. 0.043, 0.0041, 0.029). COX regressionanalysis showed that CA19-9 was an independent prognostic factor for patients with pancreatic cancer (P=0.001,95%CI 2.591~38.243). Conclusions: The detection of serum tumor markers (CA19.9, CEA, CA125 and CA242)is conducive to the early diagnosis of pancreatic cancer and joint detection of tumor markers helps improve thediagnostic efficiency. Moreover, CA19-9 is an independent prognostic factor for patients with pancreatic cancer.

The clinical value of serum CEA, CA19-9, and CA242 in the diagnosis and prognosis of pancreatic cancer.

AIM: Serum tumour markers carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and CA242 were investigated to evaluate the values of single and combined test in the diagnosis and prognosis of pancreatic cancer. METHODS: Pre-operative serum CEA, CA19-9 and CA242 were measured in 105 pancreatic cancers, 70 non-pancreatic malignancies and 30 benign pancreatic diseases. RESULTS: The sensitivity of CA19-9 alone was the highest in pancreatic cancer patients (80%), but the specificity was significantly lower than that of CEA and CA242 (P<0.01). The combination of CEA and CA242 could increase the specificity to 92%. In serum CA242 positive patients, the survival time was remarkably shorter than that of patients with negative result (P<0.01). The survival time in patients with more than two markers positive expression of CEA, CA19-9 and CA242 was obviously shorter than that of only one or no marker positive expression (P<0.05). CONCLUSION: The diagnostic rate of CA19-9 in pancreatic cancer is better than that of CEA and CA242. Combined detection of CEA and CA242 can improve the diagnostic specificity obviously. High levels of serum markers are associated with advanced stage of the disease. Patients with two or three markers positive expression of CEA, CA19-9, and CA242 simultaneously had a shorter survival time.

Combined Detection of CEA,CA 19-9, CA 242 and CA 50 in the Diagnosis and Prognosis of Resectable Gastric Cancer

Our aim was to investigate the value of combined detection of serum  carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9, CA 242 and CA 50 in diagnosis and assessment of prognosis in consecutive gastric cancer patients. Clinical data including preoperative serum CEA, CA 19-9, CA 242, and CA 50 values and information on clinical pathological factors were collected and analyzed retrospectively. Univariate and multivariate survival analyses were used to explore the relationship between tumor markers and survival. Positive rates of tumor markers CEA, CA 19-9, CA 242 and CA 50 in the diagnosis of gastric cancer were 17.7, 17.1, 20.4 and 13.8%, respectively, and the positive rate for all four markers combined was 36.6%. Patients with elevated preoperative serum concentrations of CEA, CA 19-9, CA 242 and CA 50, had late clinical tumor stageand significantly poorer overall survival. Five-year survival rates in patients with elevated CEA, CA 19-9, CA 242 and CA 50 were 28.1, 25.8, 27.0 and 24.1%, respectively, compared with 55.0, 55.4, 56.4 and 54.5% in patients with these markers at normal levels (p<0.01). In multivariate Cox proportional hazards analyses, an elevated CA 242 level was determined to be an independent prognostic marker in gastric cancer patients. Combined detection of four tumor markers increased the positive rate for gastric cancer diagnosis. CA 242 showed higher diagnostic value and CA 50 showed lower diagnostic value. In resectable gastric carcinoma, preoperative CA 242 level was associated with disease stage, and was found to be a significant independent prognostic marker in gastric cancer patients.
