Incidence of gestational trophoblastic disease in Tokat province, Turkey.

Objective: This study investigated the incidence of gestational trophoblastic disease (GTD) in Tokat province, Turkey.

Material And Methods: The medical records of patients who had been diagnosed and treated at one university hospital, six government hospitals, and one specialist hospital in Tokat province between January 2005 and December 2012 were evaluated retrospectively.

Results: During the study period, there were 59,754 births and GTD was diagnosed in 73 cases. The calculated GTD incidence was 1.22/1000. The mean age of the patients diagnosed with GTD was 28.6±7.3 (range 17-51) years. In GTD, complete moles occurred in 26%, partial moles in 74%, and no invasive moles, choriocarcinomas, or placental site trophoblastic tumours were found. Only two patients received chemotherapy (methotrexate). There was no mortality associated with the disease during follow-up.

Conclusion: The incidence of GTD in Tokat province was 1.2 per 1000 births. Early diagnosis, treatment, and follow-up play a critical role in preventing the morbidity and mortality associated with disease. The incidence of GTD, which has a high recovery rate with adequate treatment and follow-up, can be determined from regional and community-based research.
