Abstract

OBJECTIVE: The objective of this study was to describe the sonographic characteristics of squamous cell cancer (SCC) and adenocarcinoma (AC) of the cervix using transvaginal ultrasound. METHODS: Women with early stage cervical cancer undergoing transvaginal ultrasound examination before surgery were prospectively included. The sonographic characteristics were assessed with regard to tumor morphology, vascularization, size, extension and location. Histological assessment of tumor subtype, size, growth pattern, extension and location was performed. Both sonographic and histological assessments were carried out according to a standardized protocol. RESULTS: Fifty-five women were recruited. Ten were excluded because no tumor was seen on ultrasound examination and five were excluded because radical surgery was aborted as a result of positive lymph nodes, detected using the sentinel node technique. Among the remaining 40 women, 20 had AC and 20 had SCC. At pathological examination, 34 women had tumors confined to the cervix, three had parametrial invasion and three had vaginal invasion. Hypoechogenicity was associated with SCC in 73% (11/15) of the women, while isoechogenicity indicated AC in 68% (13/19) of the women (P = 0.03). Mixed echogenicity (n = 4) showed a non-significant association with larger tumor volume (P = 0.23). Hyperechogenicity was found in two women, both of whom had the less malignant villoglandular AC. Color Doppler signals were found in all cases of AC and in 90% (18/20) of cases of SCC, compared with most normal cervical tissue in which virtually no detectable vascularization was found. CONCLUSION: We found that the sonographic appearance of SCC and AC differs. This knowledge should be useful in the clinical evaluation of cervical tumors.
