Combining the staging system of the International Federation of Gynecology and Obstetrics with the scoring system of the World Heath Organization for Trophoblastic Neoplasia. Report of the Working Committee of the International Society for the Study of Trophoblastic Disease and the International Gynecologic Cancer Society

During the past 5 years the International Society for the Study of Trophoblastic Disease and the International Gynecological Cancer Society have moved to modify the staging system for trophoblastic disease by combining the staging of the International Federation of Gynecology and Obstetrics (FIGO) with the scoring system of the World Health Organization (WHO). By making significant changes in both, the classification will be more acceptable worldwide leading to uniform use by physicians reporting management results in trophoblastic disease. This is the report of the Rome Workshop, which will be presented for ratification to the FIGO Staging Committee in September 2000.
