Introduction/BackgroundEndometrial cancer is the most common malignant neoplasm of the female genital tract in developed countries, with a prevalence that is increasing. Preoperative assessment of the degree of myometrial invasion is of great importance when choosing the most appropriate treatment in terms of extension of hysterectomy and sampling of pelvic and/or para-aortic lymph nodes.ObjectivesTo determine the value of transvaginal ultrasound to diagnose the degree of myometrial invasion in the preoperative staging of endometrial cancer, comparing the results with the MRI and the anatomical part of pathology, which is the standard gold.MethodologyRetrospective observational study performed between January 2012 and December 2014. We included women with endometrial cancer diagnosed and treated at the Obstetrics and Gynecology Service of Las Palmas de Gran Canaria, where ultrasound and MRI were performed in the staging preoperative. Patients who underwent surgical treatment due to the need for an anatomical piece were included.ResultsA total of 164 patients were included, with a mean age of 66 years. The endometrioid histological type was present in 82.9% of the patients. 64.2% of the patients had an IA stage at the time of diagnosis and 17.5% had an IB stage. On the other hand, they showed a G1 53.7%, G2 18.3% and G3 27.4%. 12.2% of the patients presented relapse, living 86% of the patients without disease. The percentage of deaths is 6.1%. Transvaginal ultrasound showed a sensitivity of 60% and a specificity of 83.2%, while MRI had a sensitivity of 66% and a specificity of 80%.ConclusionTransvaginal ultrasound is a useful, accessible and inexpensive method for the study of myometrial infiltration in Endometrial Cancer, without significant differences with the results obtained with Magnetic Resonance Imaging (MRI). However, the final stage gives us the anatomical piece.DisclosureNothing to disclose.
