In conclusion, CA50 and CA125 were the most sensitive tumor markers in both endometrial carcinoma and cervical adenocarcinoma, while SCC was the most reliable antigen for squamous cell carcinoma of the cervix. Because of the affinity of SCC, CA50 and CA125 for different histological types of cervical carcinoma, the combined evaluation of SCC with CA50 or CA125 showed an increased SE with respect to each marker alone.

Abstract

CA125 (reference value [RV] = 35 U/mL), CA50 (RV = 20 U/mL), CA72.4 (RV = 3.8 U/mL) and SCC (RV = 3.6 ng/mL) levels were retrospectively assayed in blood samples collected at diagnosis from 42 patients with endometrial carcinoma, 45 patients with cervical carcinoma and 68 patients with benign uterine pathology as controls. Among the patients with endometrial carcinoma. CA50 was the antigen with the highest sensitivity (SE) (34.4%) followed by CA125 (26.2%), CA72.4 (21.9%) and SCC (16.7%). The incidence of elevated serum CA125 and CA72.4 levels was significantly greater in advanced stages than in early ones (66.7% vs 19.4%, p = 0.032 for CA125; 66.7% vs 11.5%, p = 0.012 for CA72.4), while CA50 positivity was not significantly correlated with the extent of disease (50% in advanced stages vs 30.8% in early ones, p = 0.38). Among the patients with cervical carcinoma, CA125 and CA50 respectively showed a SE of 33.3% and of 42.9% for adenocarcinoma, while SCC had a SE of 33.3% and of 42.9% for squamous cell adenocarcinoma; in particular among the patients with squamous cell carcinoma, the incidence of elevated SCC levels was correlated with the extent of tumor (57.1% in advanced stages vs 12.5% in early ones, p = 0.013). In conclusion, CA50 and CA125 were the most sensitive tumor markers in both endometrial carcinoma and cervical adenocarcinoma, while SCC was the most reliable antigen for squamous cell carcinoma of the cervix. Because of the affinity of SCC, CA50 and CA125 for different histological types of cervical carcinoma, the combined evaluation of SCC with CA50 or CA125 showed an increased SE with respect to each marker alone.
