Objectives. To study (1) the prevalence of different types of gestational trophoblastic neoplasia (GTN) in the local and nonlocal population of women at Al Wasl Hospital, a tertiary level referral centre for northern Emirates, (2) the safety of cervical preparation before uterine evacuation, (3) the role of repeat uterine evacuation in curing these cases, and (4) the percentage of cases ultimately requiring chemotherapy. Material and Methods. Retrospective analysis of case records of 35 women with diagnosis of gestational trophoblastic neoplasia were managed in the Department of Obstetrics and Gynecology at Al Wasl Hospital, over a 2-year period between January 2007 to December 2008. Results. 35 cases of gestational trophoblastic neoplasia were seen in a 2-year period (January 2007 to December 2008) at Al Wasl Hospital, with 7000 deliveries per year, prevalence being 1 in 400 live births. 60% cases were local Arabs. Histopathology revealed complete mole in 13 cases, partial mole in 17 cases, hydropic degeneration of villi in 4 cases, and no identifiable tissue in 1 case. No cases of choriocarcinoma or placental site trophoblastic tumour were seen during the study period. 34% cases received cervical preparation with prostaglandins prior to surgical curettage. Complications were minor. 62% were cured by primary suction curettage, 12% after second (repeat) uterine evacuation, and 25% needed single drug chemotherapy. 8% cases defaulted after primary evacuation and were lost to followup. Conclusions. Prevalence of GTN in the local Arab population is similar to other Asian populations. The majority of cases are cured by simple suction uterine curettage. Cervical preparation with prostaglandins should be done in selected cases to avoid perforation during evacuation. Second (repeat) uterine evacuation can be curative in some cases with strict selection criteria and avoid the need for chemotherapy. Regional registry of cases is needed to estimate the true incidence of this disease.
