Late-Breaking Abstracts

Are you conducting groundbreaking research with practice-changing potential? Do you have late-stage results or novel data that will not be available at the time of regular abstract submissions?

 

We recognise the potential importance of such studies and value to the ESGO congress attendees, members of our society and wider community.

 

We invite you to submit your Late-breaking abstracts for presentation at the 27th European Congress on Gynaecological Oncology. This is your opportunity to showcase new and impactful research for the first time at the leading European event in the field.
