Tissue polypeptide antigen (TPA), TPS, Cyfra 21-1, Cytokeratins 8-18 (CTKRS 8-18), SCC and CA 125 were measured in blood samples drawn at diagnosis from 43 patients with endometrial cancer, 47 with cervical cancer, 11 with cervical intraepithelial neoplasia (CIN), and 236 with benign uterine disease as controls. The cut-off values for all antigens were chosen at the 95th percentile of the standard Gaussian variate of controls; these limits were 98 U/L for TPA, 127 U/L for TPS, 1.6 ng/mL for Cyfra 21-1, 1.2 ng/mL for CTKRS 8-18, 48 U/mL for CA 125, and 2.8 ng/mL for SCC. TPA had the same sensitivity as SCC for squamous cell carcinoma of the cervix (42%) and a higher sensitivity than CA 125 for endometrial cancer (40% vs 12% respectively). TPA was more sensitive than TPS for both cervical (40% vs 13%) and endometrial cancer (40% vs 21%). TPA and SCC had a higher sensitivity than Cyfra 21-1 (34%) and CTKRS 8-18 (27%) for squamous cell carcinoma of the cervix. In conclusion, as for soluble cytokeratin fragments, the serum TPA seems to be the most reliable marker for the management of cervical and endometrial cancer.

Abstract

Tissue polypeptide antigen (TPA), TPS, Cyfra 21-1, Cytokeratins 8-18 (CTKRS 8-18), SCC and CA 125 were measured in blood samples drawn at diagnosis from 43 patients with endometrial cancer, 47 with cervical cancer, 11 with cervical intraepithelial neoplasia (CIN), and 236 with benign uterine disease as controls. The cut-off values for all antigens were chosen at the 95th percentile of the standard Gaussian variate of controls; these limits were 98 U/L for TPA, 127 U/L for TPS, 1.6 ng/mL for Cyfra 21-1, 1.2 ng/mL for CTKRS 8-18, 48 U/mL for CA 125, and 2.8 ng/mL for SCC. TPA had the same sensitivity as SCC for squamous cell carcinoma of the cervix (42%) and a higher sensitivity than CA 125 for endometrial cancer (40% vs 12% respectively). TPA was more sensitive than TPS for both cervical (40% vs 13%) and endometrial cancer (40% vs 21%). TPA and SCC had a higher sensitivity than Cyfra 21-1 (34%) and CTKRS 8-18 (27%) for squamous cell carcinoma of the cervix. In conclusion, as for soluble cytokeratin fragments, the serum TPA seems to be the most reliable marker for the management of cervical and endometrial cancer.
