ABSTRACT
Uterine cervical cancer is the second most common gynecological malignancy worldwide. Clinically, many early cervical cancers may be asymptomatic. Cervical tumors may have exophytic or endophytic growth. The role of ultrasound for assessing uterine cervical cancer has been considered as very limited. Cervical stromal invasion can also be estimated using transvaginal ultrasound. Cancer of the uterine cervix may be assessed by transvaginal ultrasound. Bladder and rectal involvement can also be assessed by transvaginal ultrasound. Some studies have assessed the role of ultrasound for detecting pelvic lymph node involvement in uterine cervical cancer. There are few reports about the role of Three-dimensional (3D) ultrasound for local staging of cervical cancer. Transvaginal ultrasound is highly accurate for measuring tumor size. However, when considering tumor volume estimation, 3D ultrasound is more accurate than two-dimensional (2D) ultrasound. Parametrial infiltration can be assessed by 2D ultrasound in the transverse plane of the cervix, analyzing the integrity of the pericervical fascia.
