ObjectivesBecause gestational trophoblastic disease is rare, little evidence is available from randomized controlled trials on optimal treatment and follow-up. Treatment protocols vary within Europe, and even between different centers within countries. One of the goals of the European Organization for Treatment of Trophoblastic Diseases (EOTTD) is to harmonize treatment in Europe. To provide a basis for international standardization of definitions, treatment and follow-up protocols in gestational trophoblastic disease, we evaluated differences and similarities between protocols in EOTTD countries.MethodsMembers from each EOTTD country were asked to complete an online structured questionnaire comprising multiple-choice and multiple-answer questions. The following themes were discussed: incidence of gestational trophoblastic disease and gestational trophoblastic neoplasia, definitions, guidelines, classification system, treatment, recurrence, and follow-up.ResultsForty-four respondents from 17 countries participated in this study. Guidelines were present in 80% of the countries and the FIGO (Fédération Internationale de Gynécologie et d'Obstétrique) staging and risk classification was often used to estimate risks. Agreement about when to start chemotherapy for post-molar gestational trophoblastic neoplasia was present among 66% of the respondents. Preferred first-line treatments in low- and high-risk gestational trophoblastic neoplasia were methotrexate (81%) and EMA-CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) (93%), respectively. The definition of human chorionic gonadotropin normalization after hydatidiform mole evacuation was two consecutive normal values for nine countries. The FIGO definition of post-molar gestational trophoblastic neoplasia based on human chorionic gonadotropin plateau or rise was agreed on by 69% of respondents, and only 69% and 74% defined low-risk and high-risk disease, respectively, using FIGO criteria. There were major differences in definitions of recurrence, chemotherapy resistance and follow-up protocols among countries, despite EOTTD consensus statements.ConclusionsThis questionnaire provides a good overview of current clinical practices in different countries. Based on the survey results, it is clear that there are several gestationaltrophoblastic disease-related topics that need urgent attention within the EOTTD community to create more uniformity and to aid the development of uniform guidelines in Europe.

Abstract Gestational trophoblastic disease (GTD) commonly occurs in reproductive females, but is extremely rare in perimenopausal females. In this study, we reported a case of hydatidiform mole in a 48-year-old perimenopausal female admitted due to a giant uterine mass of 28 weeks’ gestational size. The serum human chorionic gonadotropin (HCG) level ranged from 944 to 1,286 mIU/mL before treatments. The signs of preeclampsia and hyperthyroidism were relatively prominent. Hysterectomy was performed and chemotherapy was scheduled when the serum HCG level remained at a plateau, about 528 mIU/mL. The symptoms of preeclampsia and hyperthyroidism were relieved after treatment. Accordingly, we concluded that GTD could occur in perimenopausal woman and hysterectomy usually is the optimal treatment.

ObjectivesGiven the rarity of gestational trophoblastic disease (GTD), specialized regional and national centers for GTD have been established. These centers serve at least 3 purposes: to improve care for women with GTD, to enhance research though collaboration, and to educate other clinicians. This study was undertaken to understand the potential GTD knowledge gap by examining both patient and physician inquiries received at a specialized GTD center.MethodsAll electronic consults received by specialists at our center between March 2016 and March 2017 were analyzed. Information collected included source of inquiry, reason for the consult, type of GTD, and the advice provided. Descriptive statistics were used to analyze the major trends.ResultsWe analyzed 102 electronic consults. Physicians sent 49 (48%) and patients sent 53 (52%) consults. Most e-consults were sent by physicians and patients within the United States; however, 11% of the consults were directed from international locations. Among physicians, gynecologic oncologists (65%) were the most common specialty to consult our institution followed by medical oncologists (18%) and obstetrician gynecologists (16%).Most questions from gynecologic (62%) and medical oncologists (77%) concerned treatment regimens. This was contrasted by general obstetrician gynecologists who more commonly asked about human chorionic gonadotropin monitoring (62%). Difficulty with appropriate Federation of Gynecology and Obstetrics staging and World Health Organization risk score assignment were common themes. Most of the confusion centered on the use of chest computed tomography rather than plain chest x-ray for the assessment of lung metastases. Unlike physicians, patient e-consults were most concerned with the duration of human chorionic gonadotropin monitoring (51%) and timing of future conceptions.ConclusionsBoth physicians and patients in the United States and abroad frequently use electronic consults to improve their knowledge about GTD management and follow-up. Although the type of inquires varied, they highlight fundamental gaps in understanding and potential opportunities for formal education.

The present study was undertaken to investigate whether human chorionic gonadotropin (hCG) beta-core fragment (hCG beta cf) was directly produced by gestational trophoblastic tumors. Immunoreactivity of hCG beta cf was demonstrated in the extracts as well as in the culture media of hydatidiform mole tissues. It was also present in the extracts of choriocarcinoma tissues, and its molar concentration exceeded that of intact hCG. The presence of hCG beta cf was then confirmed by gel chromatography and Western blot analysis. Immunohistochemistry showed localization of hCG beta cf immunoreactivity to the syncytiotrophoblasts and scattered cells in the stroma of mole tissue, and to syncytiotrophoblastic cells in choriocarcinoma. Immunoreactivity of hCG beta cf was also detected in the sera of the patients with gestational trophoblastic disease, although the hCG beta cf/hCG ratio was less than one hundredth of that in the tissue extracts. Serial measurement of serum hCG beta cf levels after mole evacuation showed that they declined much more rapidly than those of hCG and became undetectable in the patients with subsequent spontaneous resolution, while hCG beta cf remained or became detectable before the rise of hCG was observed in the patients with subsequent persistent trophoblastic disease. Taken together, these results suggest that hCG beta cf is directly produced by gestational trophoblastic tumors, and monitoring of hCG beta cf in the serum after mole evacuation may be useful for early prediction of subsequent development of postmolar persistent trophoblastic disease.

A case of a 56-year-old woman with a mole pregnancy and a human chorionic gonadotropin (HCG)-induced thyreotoxicosis is presented. A proper diagnosis was only made after a period of patient and doctor's delay. After performing a hysterectomy, the HCG quickly normalized. Thyroid function normalized with thiamazol treatment. It is well known that older women have a higher risk to develop gestational trophoblastic disease (GTD). Furthermore, the chance of persistent trophoblastic disease is increased in this population. The literature on risk factors for developing persistent GTD and the possibilities for treatment in older patients is reviewed.

ObjectiveThe aim of this study was to compare serum human chorionic gonadotropin (hCG) levels in patients with gestational trophoblastic disease (GTD) using 2 commercially available hCG immunoassays.MethodsSerum samples were obtained from patients with GTD attending the Botucatu Medical School Trophoblastic Diseases Center of São Paulo State University (UNESP), from November 2014 to October 2015. Serum hCG levels were measured with both Architect i2000SR and Immulite 2000 XPi chemiluminescence assays. Serum hCG levels were compared against the null hypothesis. Agreement in clinical management decisions based on the hCG results was determined by comparing baseline hCG measurements and the hCG curves obtained with both assays.ResultsSeventy-three patients with GTD were included in the analysis. Of these, 45 had hydatidiform mole and spontaneous remission, whereas 28 had gestational trophoblastic neoplasia (GTN). There was a perfect (zero difference) agreement in mean hCG levels between Immulite 2000 XPi and Architect i2000 when hCG is less than 100 mIU/mL. For hCG values greater than 100 mIU/mL, there was a significant difference between assays (P< 0.05), with levels measured via Architect i2000SR being higher than those measured by Immulite 2000 XPi in patients with hydatidiform mole/spontaneous remission (R2= 90%,P< 0.01) and GTN (R2= 98%,P< 0.01). Baseline clinical management decisions showed agreement in 100% (73/37) of cases (κ = 1.0,P< 0.001), whereas decisions based on hCG curve agreed in 98% (71/72) of cases (κ = 0.93,P< 0.001).ConclusionsImmulite 2000 XPi is the most frequently recommended assay for diagnosing and monitoring patients with GTD. However, our results suggest that because Immulite 2000 XPi and Architect i2000 show very similar performance in measuring hCG levels and in determining clinical management, Architect may be used as an alternative.
