Abstract

The objective of this study was to determine the clinical presentation, treatment, and outcome of patients diagnosed with possible ectopic molar gestation registered with the Trophoblastic Disease Screening and Treatment Centre, Weston Park Hospital, Sheffield between 1986 and 2000. From the 5581 women registered, those with a diagnosis of ectopic molar pregnancy were identified from a computer database. Information regarding the relevant history of each patient and the clinical presentation, treatment, and outcomes of gestational trophoblastic disease (GTD) was determined by reviewing referral forms, case notes, and pro formas completed by the referring gynecologist. Histological review of the cases was undertaken where possible. Suspected ectopic molar gestations comprised 31/5581 (0.55%) of registrations. Known risk factors for ectopic pregnancy were identified in 79% of cases. Central histological review confirmed only six cases of GTD: three choriocarcinoma and three early complete moles. Four patients subsequently required chemotherapy. All patients are now in complete remission. We conclude that ectopic GTD is uncommon, with a UK incidence of approximately 1.5 per 1,000,000 births. Initial management is usually surgical removal of the conceptus, pathological suspicion of the diagnosis and registration with a screening center. Chemotherapy may be required and the prognosis is excellent.
