OBJECTIVE: To determine, according to histological tumor grade, the reliability of preoperative endovaginal ultrasound in the detection of myometrial invasion in patients with stage I endometrial cancer.
PATIENTS AND METHODS: Sixty-one patients with stage I endometrial carcinoma were evaluated with preoperative endovaginal ultrasound compared to postoperative results of pathologic examination, in a six-year retrospective study.
RESULTS: Twenty-nine patients had a deep myometrial invasion (stage IC). The mean endometrial thickness was 9.5 mm in stage IA, 17.0 mm in stage IB and 20.0 mm in stage IC disease (P = 0.01). The sensitivity and the specificity of the ultrasound in the assessment of myometrial invasion in grade 1 tumors were 100% and 93.7%, respectively. They fell to 69.2% and 88.9% for high-grade tumors. The global accuracy of ultrasound was 82%.
DISCUSSION AND CONCLUSIONS: The performance of preoperative ultrasound varies according to the literature. The association of morphological and morphometric criteria enables an increase in the sensitivity of the exam. In grade 1 tumors, the preoperative endovaginal ultrasound could help in identifying a group of patients at low risk of lymph node metastasis for which a pelvic lymphadenectomy would be avoidable.
