Significance of CA 72-4 in colorectal carcinoma. Comparison with CEA and CA 19-9.

In order to evaluate the usefulness of CA 72-4 tumour-associated antigen assay in colorectal carcinoma, we have studied 70 patients with benign colorectal diseases and 127 patients with colorectal cancer at different stages. The results were compared with those obtained by CEA and CA 19-9. No significant differences were found in any of the stages according to Dukes' classification when comparing stages A, B and C. However, there were differences with CEA (P < 0.001), CA 19-9 (P < 0.001) and CA 72-4 (P < 0.001) when comparing stages A, B and C with stage D. In the ROC curve, at a specificity of 95%, the sensitivities of CEA, CA 19-9 and CA 72-4 were 46.4%, 20.5% and 40.1%, respectively. In conclusion, CA 72-4 showed better sensitivity and specificity scores than CA 19-9. CEA increased individual sensitivity from 46.4% to 59.8% when combined with CA 72-4, showing a decrease of merely 0.9% in specificity.

Receiver operating characteristic (ROC) curve analysis of the tumor markers CEA, CA 19-9 and CA 72-4 in gastric cancer.

Pre-surgery serum levels of CA 72-4, CEA and CA 19-9 were quantified by the enzyme immunoassay method in 167 patients with histological diagnosis of gastric adenocarcinoma and in 92 patients with an endoscopic diagnosis of benign gastric pathology. CA 72-4 showed a better correlation between its serum levels and the different clinical stages of the disease than CEA and CA 19-9. At the individual study of stages I-II, CA 72-4 proved positive in 36.9% of patients while CEA and CA 19-9 appeared positive in 10.8% and 8.6%, respectively. In the ROC curve, at a specificity of 95%, the sensitivities of CA 72-4, CEA and CA 19-9 were 59.8%, 21% and 26.3% respectively. The discriminatory capacity of the test (area under the ROC curve +/- SD) was 0.86 +/- 0.03 in the case of CA 72-4, 0.52 +/- 0.03 for CEA and 0.58 +/- 0.03 for CA 19-9. In conclusion, in our series and with regard to CEA and CA 19-9, CA 72-4 shows better sensitivity and discriminatory capacity. CEA and CA 19-9 do not provide significant benefits when combined with CA 72-4 due to the good results obtained with the later marker alone.
