Poster Information
Abstract: The World Health Organisation classifies endometrial hyperplasia into the two categories of hyperplasia without atypia and atypical hyperplasia1. The most significant risk factor for progression to endometrial carcinoma is presence of cellular atypia2–4, however, the incidence of carcinoma beyond stage 1 in women with atypical hyperplasia on biopsy has been found to be as low as 2% following hysterectomy5. This raises the potential efficacy of conservative management in such women, who may therefore benefit from assessment of myometrial involvement with MRI prior to radical surgery6.
At present, the Royal College of Obstetricians and Gynaecologists do not recommend routine MRI of the pelvis in women with atypical hyperplasia7. We have found, however, correlations between final histological outcomes of hysterectomy specimens and several pre-operative MRI variables. More data is required to demonstrate whether quotients such as DWIq, 60CONq and 120CONq values can increase the accuracy with which MRI scans are staged. For now, we suggest MRI may have beneficial influence on the management in women with more severe histology on endometrial biopsy.
Summary: Our aim was to evaluate the role of pre-operative MRI in staging endometrial disease and so its potential to influence the management of women with atypical hyperplasia at our study centre.References: 1.Carcangiu, M.
