Summary

Objective: Gestational trophoblastic neoplasia epidemiology and treatment results in the Slovak Republic in the years 1993–2017. Methods: Retrospective analysis results of gestational trophoblastic neoplasia treatment in the Centre for gestational trophoblastic disease in the Slovak Republic in Bratislava in the years 1993–2017 according to prognostic scoring and staging system FIGO/WHO (International Federation of Gynecology and Obstetrics/World Health Organization). Results: The Centre for Gestational Trophoblastic Disease was created in the Slovak Republic in the year 1993, after the split of former Czechoslovakia. A total of 100 patients with gestational trophoblastic neoplasia were treated in this Centre in the years 1993–2017. According to prognostic scoring and staging system FIGO/ WHO, 74% patients were at a low risk and 26% of patients were at a high-risk of gestational trophoblastic neoplasia. There were 56, 2, 32 and 10% patients in stages I, II, III, and IV, respectively. The total curability and mortality rates were 96 and 4%, respectively. The curability rate 100% was achieved in stages I–III and in all placental site trophoblastic tumours, and the curability rate 60% was achieved in stage IV. In the years 1993 –2017, the incidences were 1 in 59,315 pregnancies and 1 in 42,299 deliveries for choriocarcinoma, 1 in 489,348 pregnancies and 1 in 348,965 deliveries for placental site trophoblastic tumours, 1 in 139,814 pregnancies and 1 in 99,704 deliveries for invasive mole, and 1 in 39,947 pregnancies and 1 in 28,487 deliveries for persistent gestational trophoblastic neoplasia. In the Czech Republic in the same period of time, there were treated 281 (301) patients with the curability rate 98.6% (98.7%). Conclusion: The results of the treatment of gestational trophoblastic neoplasia in the Slovak Republic are comparable with those achieved by leading centers specialized for the treatment of this disease in Europe and in the world. Early detection and centralisation of the treatment are crucial points for successful treatment, as the high curability rate of gestational trophoblastic neoplasia is achieved by effective therapy.
