Tissue polypeptide-specific antigen and CA 125 as serum tumor markers in ovarian carcinoma. 1994

A Shabana, and M Onsrud

Department of Gynecology, University Hospital, Trondheim, Norway.

The serum levels of tissue polypeptide-specific (TPS) antigen were measured using the M3 monoclonal antibody in an enzyme immunoassay in 33 patients with ovarian cancer, in 26 women with benign pelvic masses and in 26 women with a laparoscopically proven normal pelvis. The results were compared with the serum levels of the CA 125 antigen. At a cutoff level of 135 U/l for TPS and 20 U/l for CA 125 (95th percentile of the healthy controls), the sensitivity of the tests for detecting a malignant tumor was 77% for TPS and 87% for CA 125. The specificities were 85% for TPS and 92% for CA 125. Adding TPS to CA 125 did not increase the diagnostic values compared to using the CA 125 test alone. For both markers, the rate of positivity was higher in advanced stage than in early-stage ovarian cancer. No correlation between marker levels and survival was found. Serial determinations performed with 4 patients during therapy and follow-up showed that both TPS and CA 125 are good predictors of tumor response and recurrence.

D010051	Ovarian Neoplasms	Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.

D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D012680	Sensitivity and Specificity	Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)	Specificity,Sensitivity,Specificity and Sensitivity
