Finding the biomarker or biomarkers with high sensitivity and specificity in colorectal cancer, and thus a high diagnostic value will determine their clinical usefulness in clinical practice. An effective noninvasive blood test would be an ideal method to detect colorectal cancer. Discovered in 2007 a novel tumor marker CCSA-2 showes a promising results in patients with colorectal cancer.The aim of the study was the evaluation of diagnostic and clinical value of a novel marker - colon cancer specific antigen-2 (CCSA-2) in colorectal adenocarcinoma in comparison to carcinoembryonic antigen (CEA) in patients operated during the years 2008 to 2010 at Wrocław Medical University 1st Department and Clinic of General, Gastroenterological and Endocrinologic Surgery.Material and methods. The study was performed on 40 patients with colorectal cancer and 40 patients in control group consisted of healthy subjects who had colonoscopy examinations with negative results (no pathology in the colon was found). The obtained results were statistically analyzed using nonparametric tests - Mann Whitney U and Kruskal-Wallis and Spearman's rank correlation coefficients. To determine the clinical value of CCSA-2 and CEA in those groups, their sensitivity and specifity was evaluated using ROC analysis. This analysis determines the accuracy and diagnostic value of both tests.Results. There was a positive correlation between markers in patients with colorectal cancer and a statistically significant relationship according to which respondents with higher concentrations of CCSA-2 also have higher concentrations of CEA (R=0.754, p<0,001). Concentrations of tumor markers increase and correlate with the clinical progression of the disease. Accuracy of CCSA-2 test using ROC analysis showed a slightly lower measurement of antigen CCSA-2 as diagnostic value in colorectal cancer in comparison to measurement of antigen CEA (accuracy of tests: CCSA-2 - 52%, CEA - 60%).Conclusions. CCSA-2 as a single tumor marker has a low diagnostic value in colorectal cancer because of low sensitivity and specifity. The diagnostic value of novel marker is slightly lower than previously understood and accepted in clinical practice - CEA.
