ESGO-GCIG Rare Cancers Guidelines Project The European Society of Gynaecological Oncology (ESGO) and the Gynecologic Cancer Intergroup (GCIG) jointly developed clinically relevant and evidence-based algorithms for rare tumours, based on the previously elaborated initial project that was published in the Int J Gyn Cancer in 2014. The first guidelines draft was presented at the GCIG meeting in Chicago in June 2019 for comments and revision. After this meeting, both GCIG and ESGO societies circulated the different guidelines for definitive validation. Working Groups Acknowledgements ESGO and GCIG would like to express sincere gratitude to the international experts’ panel and reviewers, who devoted their time and effort to the ESGO-GCIG Rare Cancers guidelines and algorithms project. For each tumour type, two chairs from different national cooperative groups were invited to co-ordinate the activity. Each of the working groups included members from the GCIG groups, a pathologist and the ESGO methodologist, François Planchamp (France). The released Rare Cancers Algorithms Mobile App include the following tumour types prepared by the working groups below.
