title: Does preoperative serum squamous cell carcinoma antigen level predict occult extracervical disease in patients with stage Ib invasive squamous cell carcinoma of the cervix?
abstract: Preoperative serum squamous cell carcinoma antigen levels were obtained from 65 patients with International Federation of Gynecology and Obstetrics stage Ib invasive squamous cervical cancer before planned radical hysterectomy to determine whether elevated squamous cell carcinoma antigen levels (greater than 2.5 ng/mL) predicted occult extracervical extension of disease. Although the specificity of a normal level was good (0.91), the sensitivity of an elevated level was only 0.68. Not all patients with nodal metastases had elevated serum squamous cell carcinoma antigen levels; in particular, no patient with occult para-aortic nodal disease had elevated serum squamous cell carcinoma antigen.
