Results and Publications
Publication and dissemination plan
Upon completion the study will be published in peer reviewed, open access journals in order to increase the dissemination of the results generated. It will also form the basis for a thesis to be put forward for the award of a PhD at the University of Manchester and will be available to be viewed in this format. The results of the study will also be presented at national and international meetings to inform both clinicians and scientists with an interest in endometrial cancer. An abstract submission is being prepared for presentation at the European Gynaecological Oncology Congress in November 2017, submission to journals is likely to be in early 2018. Patients recruited to the study will be informed of the trial results and public engagement events will be undertaken to increase awareness of the study’s findings within the lay population.
