Introduction/Background Endometrial carcinoma is the most prevalent gynaecological malignancy in developed countries, and the 4th most frequent neoplasm in women. Staging gynaecological pelvic MRI is the best method for pre-treatment assessment, with the aim of estimating the extent of the disease. It is believed that in specialised centres, ultrasound has similar accuracy for assessing myometrial invasion. With this study our focus was to assess the accuracy of ultrasound in staging endometrial carcinoma.

Methodology A model form was created with the echographic parameters to be assessed in suspected endometrial carcinoma, in order to standardise the assessment of the extent of the disease. Statistical analysis was then carried out to analyse the agreement between echographic and surgical staging. Associations were considered statistically significant if p <0.05.

Results The form was correctly applied to 37 women diagnosed with endometrial carcinoma. The Kappa value obtained (0.178) indicated that there was no agreement between ultrasound staging and surgical staging. Although the p-value was not statistically significant, there was agreement between these variables in the majority of cases (73 per cent). There was also a weak association between the Doppler score and surgical staging (Tau value - 0.288).

Conclusion As well as being important in the diagnosis of endometrial cancer, gynaecological ultrasound also seems to play a role in its staging, especially in an initial assessment and at earlier stages, as shown in our study. It would therefore be pertinent to invest in training in gynaecological ultrasound in order to optimise the care provided, as well as from a perspective of saving resources. The small sample size could be an important limitation in our study, influencing the results obtained.
