Abstract:
Serum levels of CA-125 and squamous cell carcinoma-associated antigen (SCC) were measured in 30 patients with squamous cell carcinoma and 12 patients with adenocarcinoma of the uterine cervix. SCC was elevated in 67% of patients with squamous cell carcinoma but in only 25% of patients with adenocarcinoma. In contrast, CA-125 was elevated in 75% of patients with adenocarcinoma but in only 26% of patients with squamous cell carcinoma. These data demonstrate the applicability of the measurement of CA-125 as a tumor marker for cervical adenocarcinoma and confirm the value of the measurement of SCC antigen in patients with cervical squamous cell carcinoma. Moreover, we show that measurement of SCC antigen in adenocarcinoma and measurement of CA-125 in squamous cell carcinoma are of insufficient clinical value.
