Abstract

The Authors assayed CA 125 (cut-off value: 65 and 35 U/ml), CA 19.9 (cut-off value: 40 U/ml) and CA 72.4 (cut-off value 3.8 U/ml) immunoreactivity in blood samples drawn before surgery in 34 patients with ovarian carcinoma and in 47 patients with benign ovarian pathology. With a cut-off value of 65 U/ml, CA 125 had a sensitivity (SE) for ovarian carcinoma of 85.3%, a specificity (SP) of 89.4%, a diagnostic accuracy (DA) of 87.7%; with a cut-off value of 35 U/ml CA 125 had a SE of 88.2%, a SP of 66.0%, a DA of 75.3%; CA 19.9 had a SE of 20.6%, a SP of 70.2%, a DA of 49.4%; CA 72.4 had a SE of 64.7%, a SP of 93.6%, a DA of 81.5%. CA 125 was expressed by all ovarian carcinoma histotypes. CA 72.4 seems to have a high correlation with mucinous histotype, analogously to CA 19.9. However CA 72.4 seems to be preferable to CA 19.9 for its greater sensitivity and specificity.
