Treatment of gestational trophoblastic neoplasia according to the FIGO 2000 staging and scoring system: a 20 years’ experience

Objective. To reassess the efficacy of the Federation of Gynecology and Obstetrics (FIGO) 2000 staging and risk factor scoring system in comparison to the original World Health Organization (WHO) prognostic scoring system (1983) in a single‐institute setting. Design. Retrospective review of the medical records of 89 patients with gestational trophoblastic neoplasia. Setting. Mackay Memorial Hospital, Taipei, a regional referral center for northern Taiwan, over a 20‐year period. Methods. All selected patients were classified retrospectively by the original WHO prognostic scoring system (1983) and the FIGO 2000 system. Main outcome measure. Efficacy as the correlation of risk categorization by percentage of patients between the original WHO scoring system (1983) and the FIGO 2000 system. Results. The correlation was 97%. Only two patients were classified as middle risk group in the original WHO system (1983), but as high‐risk group by the FIGO 2000 system. Conclusion. There was good correlation between the original WHO (1983) and FIGO 2000 systems. Treatment outcomes by FIGO 2000 system were somewhat better than by the original WHO classification.
