Abstract
AIMS This study aimed to re-evaluate the incidence of hydatidiform mole (HM) and determine gestational trophoblastic disease (GTD) registration rates in Ireland following the establishment of the National GTD Registry in 2017. METHODS We performed a 3-year retrospective audit of HM cases (January 2017 to December 2019) reported in our centre. In 2019, we surveyed Irish pathology laboratories to determine the number of HMs diagnosed nationally and compared this data to that recorded in the National GTD Registry. Additionally, we compared both local and national HM incidence rates to those reported internationally. RESULTS In the 3-year local audit, we identified 87 HMs among 1856 products of conception (POCs) providing a local HM incidence rate of 3.92 per 1000 births. The 1-year pathology survey recorded 170 HMs in 6008 POCs, yielding a national incidence rate of 2.86 per 1000 births. Importantly, the local HM incidence rate exceeded the national incidence rate by 37% and the local partial HM incidence (1 in 296 births) was 64% higher than the nationally incidence rate (1 in 484 births). Notably, 42% of the HM and atypical POCs diagnosed nationally were not reported to the National GTD Registry. CONCLUSIONS Our study reveals increased HM incidence rates both locally and nationally compared with previous Irish studies. The higher local PHM incidence may reflect more limited access to ploidy analysis in other pathology laboratories nationally. Significantly, almost half of the women with diagnosed or suspected HM were not registered with the National GTD Centre.

Abstract
Complete hydatidiform mole with coexisting fetus (CHMCF) is rare, and diagnosis is challenging due to limited data. Here, we present the case of a patient with noninvasive prenatal test (NIPT) resulting in "likely molar pregnancy" in the second trimester. Subsequent ultrasound confirmed a cystic appearing portion of the placenta. At 22 weeks, the patient delivered a demised fetus and two placentas. Pathology was consistent with CHMCF. This case is the first to show primary detection of a CHMCF with single-nucleotide polymorphism (SNP)-based NIPT prior to ultrasound identification. Our case suggests the use of SNP-based NIPT as an alternative noninvasive method to guide shared decision-making and clinical management for patients with this diagnosis.

Am J Obstet Gynecol 2021; 225:513.e1-513.e19. [PMID: 34058170 PMCID: PMC9941751 DOI: 10.1016/j.ajog.2021.05.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 05/24/2021] [Accepted: 05/24/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Historically, published guidelines for care after molar pregnancy recommended monitoring human chorionic gonadotropin levels for the development of gestational trophoblastic neoplasia until normal and then for 6 months after the first normal human chorionic gonadotropin. However, there are little data underlying such recommendations, and recent evidence has demonstrated that gestational trophoblastic neoplasia diagnosis after human chorionic gonadotropin normalization is rare. OBJECTIVE We sought to estimate the cost-effectiveness of alternative strategies for surveillance for gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after complete and partial molar pregnancy. STUDY DESIGN A Markov-based cost-effectiveness model, using monthly cycles and terminating after 36 months/cycles, was constructed to compare alternative strategies for asymptomatic human chorionic gonadotropin surveillance after the first normal (none; monthly testing for 1, 3, 6, and 12 months; or every 3-month testing for 3, 6, and 12 months) for both complete and partial molar pregnancy. The risk of reduced surveillance was modeled by increasing the probability of high-risk disease at diagnosis. Probabilities, costs, and utilities were estimated from peer-reviewed literature, with all cost data applicable to the United States and adjusted to 2020 US dollars. The primary outcome was cost per quality-adjusted life year ($/quality-adjusted life year) with a $100,000/quality-adjusted life year willingness-to-pay threshold. RESULTS Under base-case assumptions, we found no further surveillance after the first normal human chorionic gonadotropin to be the dominant strategy from both the healthcare system and societal perspectives, for both complete and partial molar pregnancy. After complete mole, this strategy had the lowest average cost (healthcare system, $144 vs maximum $283; societal, $152 vs maximum $443) and highest effectiveness (2.711 vs minimum 2.682 quality-adjusted life years). This strategy led to a slightly higher rate of death from gestational trophoblastic neoplasia (0.013% vs minimum 0.009%), although with high costs per gestational trophoblastic neoplasia death avoided (range, $214,000 to >$4 million). Societal perspective costs of lost wages had a greater impact on frequent surveillance costs than rare gestational trophoblastic neoplasia treatment costs, and no further surveillance was more favorable from this perspective in otherwise identical analyses. No further surveillance remained dominant or preferred with incremental cost-effectiveness ratio of <$100,000 in all analyses for partial mole, and most sensitivity analyses for complete mole. Under the assumption of no disutility from surveillance, surveillance strategies were more effective (by quality-adjusted life year) than no further surveillance, and a single human chorionic gonadotropin test at 3 months was found to be cost-effective after complete mole with incremental cost-effectiveness ratio of $53,261 from the healthcare perspective, but not from the societal perspective (incremental cost-effectiveness ratio, $288,783). CONCLUSION Largely owing to the rare incidence of gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after molar pregnancy, prolonged surveillance is not cost-effective under most assumptions. It would be reasonable to reduce, and potentially eliminate, current recommendations for surveillance after human chorionic gonadotropin normalization after molar pregnancy, particularly among partial moles. With any reduction in surveillance, patients should be counseled on symptoms of gestational trophoblastic neoplasia and established in routine gynecologic care.

Abstract
Methotrexate (MTX) is the primary pharmaceutical agent that is used for management of disorders arising from trophoblastic tissue. Its widespread international use is mostly attributable to its noninvasive, safe, and effective characteristics as a treatment option for ectopic pregnancy (EP) and gestational trophoblastic disease (GTD), with the large added benefit of fertility preservation. Although the effects of MTX usage are well documented in the gynecologic and obstetric literature, there is a scarcity of radiologic literature on the subject. Depending on the type of EP, the route of MTX administration and dosage may vary. US plays an essential role in the diagnosis and differentiation of various types of EPs, pregnancy-related complications, and complications related to MTX therapy, as well as the assessment of eligibility criteria for MTX usage. A knowledge of expected imaging findings following MTX treatment, including variability in echogenicity and shape of the EP, size fluctuations, changes in vascularity and gestational sac content, and the extent of hemoperitoneum, is essential for appropriate patient management and avoidance of unnecessary invasive procedures. A recognition of sonographic findings associated with pregnancy progression and complications such as tubal or uterine rupture, severe hemorrhage, septic abortion, and development of arteriovenous communications ensures prompt patient surgical management. The authors discuss the use of MTX in the treatment of disorders arising from trophoblastic tissue (namely EP and GTD), its mechanism of action, its route of administration, and various treatment regimens. The authors also provide a focused discussion of the role of US in the detection and diagnosis of EP and GTD, the assessment of the eligibility criteria for MTX use, and the identification of the sonographic findings seen following MTX treatment, with specific emphasis on imaging findings associated with MTX treatment success and failure.

Abstract
OBJECTIVE This guideline reviews the clinical evaluation and management of gestational trophoblastic diseases, including surgical and medical management of benign, premalignant, and malignant entities. The objective of this guideline is to assist health care providers in promptly diagnosing gestational trophoblastic diseases, to standardize treatment and follow-up, and to ensure early specialized care of patients with malignant or metastatic disease. INTENDED USERS General gynaecologists, obstetricians, family physicians, midwives, emergency department physicians, anaesthesiologists, radiologists, pathologists, registered nurses, nurse practitioners, residents, gynaecologic oncologists, medical oncologists, radiation oncologists, surgeons, general practitioners in oncology, oncology nurses, pharmacists, physician assistants, and other health care providers who treat patients with gestational trophoblastic diseases. This guideline is also intended to provide information for interested parties who provide follow-up care for these patients following treatment. TARGET POPULATION Women of reproductive age with gestational trophoblastic diseases. OPTIONS Women diagnosed with a gestational trophoblastic disease should be referred to a gynaecologist for initial evaluation and consideration for primary surgery (uterine evacuation or hysterectomy) and follow-up. Women diagnosed with gestational trophoblastic neoplasia should be referred to a gynaecologic oncologist for staging, risk scoring, and consideration for primary surgery or systemic therapy (single- or multi-agent chemotherapy) with the potential need for additional therapies. All cases of gestational trophoblastic neoplasia should be discussed at a multidisciplinary cancer case conference and registered in a centralized (regional and/or national) database. EVIDENCE Relevant studies from 2002 onwards were searched in Embase, MEDLINE, the Cochrane Central Register of Controlled Trials, and Cochrane Systematic Reviews using the following terms, either alone or in combination: trophoblastic neoplasms, choriocarcinoma, trophoblastic tumor, placental site, gestational trophoblastic disease, hydatidiform mole, drug therapy, surgical therapy, radiotherapy, cure, complications, recurrence, survival, prognosis, pregnancy outcome, disease outcome, treatment outcome, and remission. The initial search was performed in April 2017 and updated in May 2019. Relevant evidence was selected for inclusion in the following order: meta-analyses, systematic reviews, guidelines, randomized controlled trials, prospective cohort studies, observational studies, non-systematic reviews, case series, and reports. Additional significant articles were identified through cross-referencing the identified reviews. The total number of studies identified was 673, with 79 studies cited in this review. VALIDATION METHODS The content and recommendations were drafted and agreed upon by the authors. The Executive and Board of Directors of the Society of Gynecologic Oncology of Canada reviewed the content and submitted comments for consideration, and the Board of Directors for the Society of Obstetricians and Gynaecologists of Canada approved the final draft for publication. The quality of evidence was rated using the criteria described in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology framework. See the online appendix tables for key to grading and interpretation of recommendations. BENEFITS These guidelines will assist physicians in promptly diagnosing gestational trophoblastic diseases and urgently referring patients diagnosed with gestational trophoblastic neoplasia to gynaecologic oncology for specialized management. Treating gestational trophoblastic neoplasia in specialized centres with the use of centralized databases allows for capturing and comparing data on treatment outcomes of patients with these rare tumours and for optimizing patient care.

Abstract
OBJECTIVE To estimate the incidence of gestational trophoblastic neoplasia following complete and partial molar pregnancy after reaching normal human chorionic gonadotropin (hCG) levels to guide evidence-based follow-up recommendations. DATA SOURCES MEDLINE, EMBASE, Web of Science, POPLINE, Cochrane, and ClinicalTrials.gov were searched from inception to November 2018, using the intersection of "gestational trophoblastic disease," "molar pregnancy," and "human chorionic gonadotropin" themes. METHODS OF STUDY SELECTION Search results were screened to identify cohort studies of molar pregnancy reporting gestational trophoblastic neoplasia development, with at least 6 months of intended normal hCG follow-up. TABULATION, INTEGRATION, AND RESULTS Two reviewers independently identified articles for inclusion. Data were extracted using a standardized form. For meta-analysis, cumulative incidence of gestational trophoblastic neoplasia, with CIs by the Agresti-Coull method, and pooled risk ratios (RRs) comparing complete and partial mole were calculated. Among the 19 eligible studies that reported adequate data for inclusion in the primary meta-analysis, we found low incidence of gestational trophoblastic neoplasia after normal hCG level following both complete mole (64/18,357, 0.35%, 95% CI 0.27-0.45%), and partial mole (5/14,864, 0.03%, 95% CI 0.01-0.08%). There was a significantly higher risk of gestational trophoblastic neoplasia after complete compared with partial molar pregnancy (RR 4.72, 95% CI 1.81-12.3, P=.002). Among gestational trophoblastic neoplasia cases after normal hCG level following complete mole, 89.6% occurred when the time from evacuation to normalization was 56 days or longer, and 60.7% were diagnosed beyond the commonly recommended 6-month surveillance interval. Sensitivity analyses, including those limiting to studies at low risk of bias, did not significantly affect results. We found an overall incidence of gestational trophoblastic neoplasia of 15.7% for complete mole (1,354/8,611, 95% CI 15.0-16.5%) and 3.95% for partial mole (221/5,593, 95% CI 3.47-4.50%). CONCLUSION Gestational trophoblastic neoplasia development after normal hCG level following molar pregnancy is rare. Recommendations for frequency and duration of hCG follow-up can be minimized to lessen burden on patients and informed by the type of molar pregnancy and time interval from uterine evacuation to hCG normalization.

Abstract
OBJECTIVES Given 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. METHODS All 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. RESULTS We 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. CONCLUSIONS Both 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.

A Novel Prediction Model for Postmolar Gestational Trophoblastic Neoplasia and Comparison With Existing Models. Int J Gynecol Cancer 2018; 27:1028-1034.

Abstract
OBJECTIVE The aim of this study was to comparatively study a novel model and existing models of predicting postmolar gestational trophoblastic neoplasia (GTN). METHODS Two hundred twenty-two patients with complete hydatidiform moles were enrolled retrospectively. A natural regression was noted in 195 patients (spontaneous regression group), whereas the remaining 27 patients entered postmolar GTN (postmolar GTN group). The upper limits of the 95% confidence interval of human chorionic gonadotropin (hCG) values and hCG regression rates were calculated aggregately from the spontaneous regression group. The 4 prediction models (weekly hCG regression curve and weekly hCG regression rate curve reported by previous studies; daily hCG regression curve and daily hCG regression rate curve pioneered by us) were then plotted. The individual hCG curve of the postmolar GTN group was plotted and compared with the prediction models, respectively. The individual hCG curve superimposing the prediction curve was considered showing an elevated risk of GTN. RESULTS All patients with postmolar GTN were preidentified by daily hCG regression rate curve. The other 3 prediction models had a considerable rate of failure in identification. Mean diagnosis time of daily hCG regression rate curve was significantly lower (P = 0.008), with an average of 15.3 days gained compared with International Federation of Gynecology and Obstetrics criteria. Cochran Q test showed that daily hCG regression rate curve produced a significantly better performance in predicting postmolar GTN than weekly hCG regression curve (P = 0.01). CONCLUSIONS Our data showed that daily hCG regression rate curve gives a better prediction of postmolar GTN and might potentially enhance the monitoring of patients with molar pregnancy, especially those who could not adhere to International Federation of Gynecology and Obstetrics protocols. However, this preliminary research should not change current clinical practice until further validation is carried out.

Abstract
OBJECTIVE To evaluate the efficacy and safety of second uterine curettage in lieu of chemotherapy for patients with low-risk, nonmetastatic gestational trophoblastic neoplasia (GTN) and to evaluate whether response to second curettage is independent of patient age, World Health Organization (WHO) risk score, registration human chorionic gonadotropin (hCG) level, lesion size, and depth of myometrial invasion measured on ultrasound examination. METHODS This was a cooperative group multicenter prospective phase II study. Prestudy testing included quantitative hCG level, pelvic ultrasonography, and chest radiography. Patients were categorized according to WHO risk scoring criteria (low risk with a score of 0-6). RESULTS Sixty-four women with newly diagnosed low-risk, nonmetastatic GTN were enrolled. Four patients were excluded. Twenty-four patients (40%) (lower 95% confidence limit 27.6%) were cured after second curettage. An additional two patients (3%) achieved a complete response but did not complete follow-up. Overall, 26 of 60 patients were able to avoid chemotherapy. Surgical failure was observed in 34 women (59%) and was more common in women 19 years old or younger or 40 years old or older. One case of grade 1 uterine perforation was successfully managed by observation. Four grade 1 and one grade 3 uterine hemorrhages were reported. New metastatic disease (lung) was identified in one of these women after second curettage. In three patients (surgical failures), the second curettage pathology was placental site trophoblastic tumor, and it was placental nodule in one additional patient. CONCLUSION Second uterine curettage as initial treatment for low-risk, nonmetastatic GTN cures 40% of patients without significant morbidity.

Complete molar pregnancy with transformation to choriocarcinoma of the liver: A case report. Case Rep Womens Health 2016; 12:11-14.

Abstract
Objective Highlight a complete molar pregnancy with possible complications and pertinent clinical information to aid doctors in recognizing the disease quickly to provide treatment to limit adverse outcomes. Context Complete molar pregnancy is rare and compromises 1:500–1:2000 pregnancies [1-4]. As technology has improved, the presentation of complete molar pregnancy has changed [1,5-6]. Summary A 19-year old African American female presented to the emergency room (ER) three times within 14 days for abdominal pain. A pregnancy test was positive and on the third visit quantitative β-human chorionic gonadotropin (HCG) was elevated without signs of an intrauterine pregnancy (IUP). Dilation and curettage (D&C) was done with small perforation of the uterus. Pathology report indicated a complete molar pregnancy. The patient failed to follow-up and returned to ER 22 days later where an abdominal mass was found prompting surgery. Hematomas and abdominal adhesions were removed and again pathology showed a complete molar pregnancy. Follow-up HCG levels failed to decrease appropriately so the patient was referred to oncology where metastatic choriocarcinoma of the liver was diagnosed. Chemotherapy was initiated and HCG monitored. Patient was readmitted for infections and complications, but did eventually have her HCG return to zero. Data sources Clinical Key, Purdue Library, and UpToDate were used to search for literature. Conclusion Prompt recognition of a complete mole may lead to a less extensive disease process. Presentation has recently changed so it is important to know signs. Patient compliance likely results in fewer complications and costs. Complete molar pregnancy is rare. As technology has improved, the presentation of complete molar pregnancy has changed. Prompt recognition of a complete mole may lead to a less extensive disease process.

Apoptotic index for prediction of postmolar gestational trophoblastic neoplasia. Am J Obstet Gynecol 2016; 215:336.e1-336.e12.

Abstract
BACKGROUND Although 85% of patients with a complete hydatidiform mole achieve spontaneous remission after a few months, 15% of them will experience gestational trophoblastic neoplasia, which requires chemotherapy. To date, there is no biomarker to predict post-molar gestational trophoblastic neoplasia before the initiation of human chorionic gonadotropin surveillance. OBJECTIVE The purpose of this study was to assess the relationship between the expression of apoptosis markers in the molar villous trophoblasts and the subsequent development of gestational trophoblastic neoplasia after the evacuation of a complete hydatidiform mole. STUDY DESIGN This was a retrospective cohort study of patients with complete hydatidiform mole who were diagnosed, treated, and followed at the Center of Trophoblastic Diseases (Botucatu/São Paulo State and Rio de Janeiro/Rio de Janeiro State, Brazil) from 1995-2014. Patients were divided temporally into derivation (1995-2004) and validation (2005-2014) cohorts. Immunohistochemistry was used to examine tissue expression of the apoptosis inhibitor survivin or the pro-apoptotic enzyme caspase-3. Survivin stains for cytoplasmic and nuclear expression were evaluated independently. Caspase-3 expression was measured as an apoptotic index of positive staining cells over negative staining cells multiplied by 100. Receiver operating characteristic curves were then constructed, and the area under the curve was calculated to test the performance characteristics of the staining to predict the subsequent development of gestational trophoblastic neoplasia. RESULTS The final study population comprised 780 patients, with 390 patients in each temporal cohort: 590 patients entered spontaneous remission, and 190 patients experienced post-molar gestational trophoblastic neoplasia. Neither nuclear nor cytoplasmic survivin expression performed well as a predictor of subsequent gestational trophoblastic neoplasia. The caspase-3 apoptotic index was a strong risk factor for subsequent gestational trophoblastic neoplasia development. When the apoptotic index was <4%, the risk of gestational trophoblastic neoplasia had an odds ratio of 35.55 (95% confidence interval, 14.02-90.14; P < .0001) in the derivation cohort and an odds ratio of 25.71 (95% confidence interval, 10.13-65.29; P < .0001) in the validation cohort. However, in both cohorts, the positive predictive value for gestational trophoblastic neoplasia of an apoptotic index <4.0% was modest (49% in the derivation cohort and 41% in the validation cohort); the negative predictive value for gestational trophoblastic neoplasia of an apoptotic index ≥4.0% was high (97% in both cohorts). CONCLUSION The subsequent development of gestational trophoblastic neoplasia after evacuation of complete hydatidiform mole is tied closely to the apoptotic index, which may be a useful biomarker for future prospective studies.

Abstract
BACKGROUND In randomized clinical trials or observational studies, it is common to collect biomarker values longitudinally on a cohort of individuals. The investigators may be interested in grouping individuals that share similar changes of biomarker values and use these groups for diagnosis or therapeutic purposes. However, most classical model-based classification methods rely mainly on empirical models such as splines or polynomials and do not reflect the physiological processes. METHODS A model-based classification method was developed for longitudinal biomarker measurements through a pharmacokinetic model that describes biomarker changes over time. The method is illustrated using data on human Chorionic Gonadotrophic Hormone measurements after curettage of hydatidiform moles. RESULTS The resulting classification was linked to the evolution toward gestational trophoblastic neoplasia and may be used as a tool for early diagnosis. The diagnostic accuracy of the pharmacokinetic model was more reproducible than the one of a purely mathematical model that did not take into account the biological processes. CONCLUSION The use of pharmacokinetic models in model-based classification approaches can lead to clinically useful classifications.

Abstract
OBJECTIVE The aim of this study was to reach a publicly applicable marker, using the increasing or decreasing trend of different forms of β-human chorionic gonadotropin (β-hCG) during the first 28 days after molar pregnancy evacuation. METHODS The present retrospective cohort study investigated all of the documents of patients with hydatidiform mole according to their pathological results during their admission and follow-up in the past 10 years (2003-2013). The type of the relationship was determined using locally weighted scatterplot smoothing (Lowess Smoother) and fractional polynomial regression (Fracpoly), and then a model tailored to data processing was used for drawing the receiver operating characteristic curve. During the investigation of gestational trophoblastic neoplasia (GTN) risk factors, the multiple logistic regression method was used to control the confounding variables. RESULTS Among individuals with high-risk molar pregnancy, 11 (18%) had GTN, and the prevalence of GTN in individuals with low-risk molar pregnancy was 13.4%. The slope of the β-hCG line slightly decreases with a rate of change close to zero in individuals with GTN, but the decrease is not statistically significant (P > 0.05). The receiver operating characteristics curve for serum β-hCG measurement after 21 days of molar pregnancy evacuation showed 83% sensitivity at 89% specificity (area under the curve, 0.9), which indicates that this variable has an optimal performance for discrimination between the GTN cases and patients who had spontaneous disease remission. The mean times of reaching the first negative titer in those without neoplasia and reaching a definitive GTN diagnosis were 8.1 (SD, 2) and 6.2 (SD, 1.5), respectively. The most effective remaining variable in the logistic model was uterine size larger than gestational age (95% confidence interval, 0.99-1.31; odds ratio, 1.14) with a slight increase in the risk and borderline significance (P = 0.07). CONCLUSIONS The serum β-hCG measurement after 21 days of molar pregnancy evacuation and slope of the linear regression line of β-hCG showed to be a good test to discriminate between patients who will get spontaneous disease remission and patients developing GTN.

Abstract
Gestational trophoblastic disease includes complete hydatidiform mole (CHM) or partial hydatidiform mole (PHM) and gestational trophoblastic neoplasia (GTN). Given the very high-curability rate of trophoblastic disease, the risk of further molar pregnancy after CHM or PHM as well as the risk of second primary tumors and fertility compromise after chemotherapy for GTN represent major concerns. The incidence of subsequent molar pregnancy ranges from 0.7 to 2.6% after one CHM or PHM, and is approximately 10% after two previous CHMs. Among patients who have received chemotherapy, there is an increased risk of myeloid leukemia which is mainly related to the cumulative dose of etoposide. Resumption of normal menses occurs in approximately 95% of women treated with chemotherapy, but menopause occurs 3 years earlier compared with those non-treated with chemotherapy. Term live birth rates higher than 70% without increased risk of congenital abnormalities have been reported in these women, and pregnancy outcomes are comparable to those of general population, except a slightly increased risk of stillbirth. Fertility-sparing treatment for placental site trophoblastic tumor is a therapeutic option reserved to highly selected, young women who do not present markedly enlarged uterus or diffuse multifocal disease within the uterus.

Abstract
β -human chorionic gonadotropin (HCG) level is not a reliable marker for early identification of persistent gestational trophoblastic neoplasia (GTN) after evacuation of hydatidiform mole. Thus, this study was conducted to evaluate β -HCG regression after evacuation as a predictive factor of malignant GTN in complete molar pregnancy. Methods. In this cross-sectional study, we evaluated a total of 260 patients with complete molar pregnancy. Sixteen of the 260 patients were excluded. Serum levels of HCG were measured in all patients before treatment and after evacuation. HCG level was measured weekly until it reached a level lower than 5 mIU/mL. Results. The only predictors of persistent GTN are HCG levels one and two weeks after evacuation. The cut-off point for the preevacuation HCG level was 6000 mIU/mL (area under the curve, AUC, 0.58; sensitivity, 38.53%; specificity, 77.4%), whereas cut-off points for HCG levels one and two weeks after evacuation were 6288 mIU/mL (AUC, 0.63; sensitivity, 50.46%; specificity, 77.0%) and 801 mIU/mL (AUC, 0.80; sensitivity, 79.82%; specificity, 71.64%), respectively. Conclusion. The rate of decrease of HCG level at two weeks after surgical evacuation is the most reliable and strongest predictive factor for the progression of molar pregnancies to persistent GTN.

Methotrexate was developed in 1949 as a synthetic folic acid analogue to compete with folic acid and thus interfere with cell replication. While initially developed as a potential treatment for acute lymphoblastic leukaemia, a serendipitous observation led to methotrexate's use to effect the dramatic cure of a case of advanced choriocarcinoma. This prompted the exploration for the potential of methotrexate to treat other conditions involving disordered trophoblastic tissue. Methotrexate has subsequently revolutionized the treatment of two pregnancy-related conditions—gestational trophoblastic neoplasia and ectopic pregnancy. This article reviews the development of modern treatment protocols that use methotrexate to medically treat these two important gynaecological conditions.

Abstract
OBJECTIVE The objective of this study is to examine the outcomes of combined chemotherapy using methotrexate and dactinomycin in the management of women with low-risk gestational trophoblastic neoplasia (GTN). The primary outcome is the total number of cycles of chemotherapy required to achieve a normal level of human chorionic gonadotropin (hCG). The secondary outcome is treatment-related toxicity. METHODS A retrospective chart review of all patients with GTN treated between 1996-2007 and 1991-2007 was performed at the Alberta Cross Cancer Institute and the British Columbia Cancer Agency, respectively. Patients with low-risk GTN, treated with 0.6 mg/m(2) dactinomycin (days 1 and 2) and methotrexate 100mg/m(2) were included. Toxicities were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events. The number of cycles to achieve normalization of hCG was determined, and multivariate analyses were performed to identify factors associated with treatment duration. RESULTS One hundred women were eligible. The average age was 29 years (range 15-46). The median number of cycles to achieve a normal hCG was 3 (range 1-11). Two patients required second-line treatment and one patient chose to proceed with hysterectomy. Ninety-eight percent of patients were primarily cured with this regimen, and 2 were cured with second line treatment. Grade 3 and 4 hematologic toxicities were experienced by 12% and 8% of patients, respectively. Grade 2 and 3 stomatitis or mucositis were noted in 44% and 3% of patients, respectively. CONCLUSIONS Low-risk GTN is reliably and rapidly cured with combined methotrexate-dactinomycin. Toxicity is modest.

Abstract
BACKGROUND Previous studies on the significance of hCG to predict gestational trophoblastic neoplasia (GTN) have been too small for robust conclusions to be reached. Our aim in this study was to analyse the significance of urine hCG in predicting GTN in a large population. METHODS Details of 3926 patients were available for analysis. Information regarding age, dates of diagnosis and registration, urine hCG levels, antecedent pregnancy and chemotherapy were prospectively collected and used for analyses. Patients were stratified into different groups according to urine hCG level (IU/L); < 50, 50-99, 100-249, 250-499, 500-999, 1000-9999 and ≥10,000. Multivariate analyses were used to identify the prognostic indicators of GTN. RESULTS Urine hCG and antecedent pregnancy were the most powerful indicators for developing GTN (P<0.01). None of the patients with partial mole and urine hCG <50 IU/L (Normal level=40 IU/L) developed GTN. The risk of GTN was >35% in all patients with urine hCG ≥500 IU/L. GTN developed in 70% of patients with complete mole and urine hCG ≥10,000 IU/L. CONCLUSION Urine hCG is sensitive test for GTN. Urine hCG level is a powerful prognostic indicator for the GTN. Patients with partial mole could be safely discharged from the surveillance programme once their hCG have normalised. Patients with urine hCG ≥249 IU/L, whether partial or complete molar pregnancy, appear to benefit from intensive surveillance. Prophylactic chemotherapy could be considered when there are problems with surveillance.

Abstract
BACKGROUND The major concern in gestational trophoblastic disease is management of persistent disease and malignant sequelae. However, prediction of response to treatment is difficult and methods used controversial. AIM AND METHODS To evaluate the usefulness of clinical presentation, methods of diagnosis and categorisation of risk in determining clinical outcomes, by analysis of a database of 705 registered patients collected over 30 years. RESULTS From the database, there were 97 patients who developed persistent disease and malignant sequelae on the basis of defined criteria - 80.4% had molar pregnancy and 19.6% non-molar pregnancy. Vaginal bleeding was not a common presentation; 59.8% had no clinical symptoms. According to protocol, monitoring by serial human chorion gonadotrophin (HCG) levels followed by imaging screen was used in all patients; histology was also available in 41.2% from hysterectomy and curettage specimens. There were 16 of 76 patients with persisting disease who had metastases (21.1%), and 2 of 20 patients with choriocarcinoma who had an antecedent molar pregnancy (10.0%). Based on five risk factors, 25 patients were categorised as 'high risk' and assigned to receive multi-drug chemotherapy. There were two deaths (2.1% for all malignant sequelae); both were from molar pregnancies. One patient failed to respond and the other suffered a complication of intensive chemotherapy. CONCLUSION Serial HCG levels remain the best monitor to determine therapeutic response. Categorisation of 'high risk' by five factors is useful in treatment. Albeit a small series, clinical outcome is favourable with a five-year survival of 89.7%.

Abstract
Gestational trophoblastic disease (GTD) is a group of interrelated tumours originating from the placenta. Hydatidiform molar (HM) pregnancy is the most common form of GTD; this includes both partial hydatidiform molar (PHM) and complete hydatidiform molar (CHM) pregnancies. The importance of such a condition derives from its potential for persistent trophoblastic disease; this is noted to be more common after a CHM (10-20%) compared to a PHM (0.1-11%). The recent routine use of high-resolution trans-vaginal ultrasound (TVS) in early pregnancy has improved the recognition and thus pre-surgical diagnosis of molar pregnancy. Pre-surgical recognition aids planning of surgery, decreases intra-operative complications and identifies women with potential persistent trophoblastic disease. Despite the introduction of TVS, its performance in preoperative diagnosis is quite poor. This is primarily because of the histomorphometric features of the hydropic villi. A significant proportion of HM cases demonstrates minimal hydropic change in the first trimester and therefore is likely to remain unidentifiable by ultrasound examination prior to surgical evacuation, even with improved sonographer expertise. The overall sensitivity for the ultrasound diagnosis of HM is 50-86%. Ultrasound diagnosis of CHM can be made in approximately 80% of the cases, whilst ultrasound diagnosis of PHM is less accurate and nearly 70% of cases will be missed. Correlation of the ultrasonographic findings with human chorionic gonadotropin levels can further improve the recognition of HM pregnancy pre-surgery. Although ultrasound can be helpful in the diagnosis of molar pregnancies, histological confirmation is mandatory. Histological confirmation post-curettage is still the gold standard for the diagnosis of GTD. In this article, we critically evaluate the role of TVS in the pre-surgical recognition of GTD.

Abstract
Van Trommel et al have previously shown that serum human chorionic gonadotropin (hCG) cutoff levels can provide early prediction of resistance to first-line methotrexate (MTX) in patients with persistent trophoblastic disease (PTD). In this study, we validate this approach of prediction of resistance to single-agent chemotherapy in an independent and larger cohort of PTD patients using a different hCG assay. Receiver operating characteristics (ROC) curves were constructed to determine hCG cutoff levels and sensitivity between patients cured on single-agent chemotherapy (control group) and patients requiring change to combination chemotherapy (study group). Receiver operating characteristics analysis identified an hCG cutoff value of 737 IU l−1 that enabled us to predict the subsequent development of single-agent chemotherapy resistance in 52% of patients before their fourth MTX course at 97.5% specificity. This would have enabled an earlier switch to combination chemotherapy reducing the MTX exposure by an average of 2.5 courses. The present findings confirm that serum hCG cutoff levels predict resistance to single-agent therapy earlier than traditional methods. Change to combination chemotherapy should be considered for patients whose serum hCG levels exceed these hCG cutoff values. For patients not exceeding the hCG cutoff levels, static or rising hCG levels should still be included in the criteria for change of chemotherapy.

Abstract
OBJECTIVES To determine the risk for recurrent trophoblastic disease after spontaneous normalization of human chorionic gonadotropin (hCG) levels in patients with hydatidiform mole and to determine the risk for tumor relapse after apparent remission following chemotherapy in patients with low- and high-risk persistent trophoblastic disease. METHODS From 1994 until 2004, 355 patients with hydatidiform mole were registered at the Dutch Central Registry of Hydatidiform Mole and were monitored by sequential hCG assays in serum at the department of Chemical Endocrinology of the Radboud University Nijmegen Medical Centre. HCG regression curves were analyzed together with clinical information collected from the Hydatidiform Mole Database. RESULTS Among the 355 registered hydatidiform mole patients, 265 patients attained spontaneous normalization following evacuation. Of the 265 patients, one patient (0.38%) subsequently required chemotherapeutic treatment for recurrent trophoblastic disease (95% confidence interval 0.0% to 2.1%). HCG levels did not decline to normal (<2.0 ng/ml) spontaneously in 90 patients; those patients were subsequently treated. Relapse rates were 8.1% (6/74) and 6.3% (1/16) for the low- and high-risk category respectively. CONCLUSION Our analysis indicates that relapse risk in hydatidiform mole patients with spontaneous normalization is extremely low (one in 265 patients) after two normal hCG levels (<2.0 ng/ml) are achieved. Our results support the suggestion that two subsequent normal hCG levels may be sufficient to ensure sustained remission after hydatidiform mole evacuation. In contrary, in order to assure sustained remission, the relapse rates after chemotherapy in the current study emphasize the need for surveillance of trophoblastic tumor patients even after complete remission has apparently been achieved.

Abstract
OBJECTIVE The aim of the present study was to asses the ability of Her-2/neu immunohistochemical staining of the molar tissue to predict the risk of developing gestational trophoblastic neoplasia (GTN). METHODS Sections prepared from 33 consecutive formalin-fixed paraffin-embedded archival reconfirmed hydatidiform mole tissue blocks were immunohistochemically stained for Her-2/neu. The staining was scored according to the subjectively evaluated intensity of staining and the proportion of stained villous cytotrophoblastic cells. Clinical data were abstracted from medical files. RESULTS 23 patients had a complete and 10 a partial mole. Nine patients (27.3%) were diagnosed with GTN [7 of 23 patients with a complete mole (30.4%) and 2 of the 10 (20.0%) with a partial mole]. A positive immunohistochemical Her-2/neu stain was found in 6 (18.2%) of the patients with hydatidiform mole (3 with a complete mole). The rate of Her-2/neu expression was somewhat higher in moles with subsequent GTN than in moles with an uneventful course (22.2% vs. 16.6%, respectively). The difference did not reach significance (Fisher's Exact Test, P=0.55) possibly due to the small number of cases (power of <5%). The sensitivity and specificity of Her-2/neu expression for prediction of GTN was 22.2% and 83.3%, respectively, and the positive and negative predictive value 33.3% and 74.1%, respectively. CONCLUSION While the specificity of Her-2/neu immunohistochemical staining for prediction of GTN is relatively high, the low sensitivity and low positive and negative predictive value precludes its practical clinical use for prediction of post-molar GTN. The quest for a precise predictor of post-molar GTN should continue.

Abstract
Hydatidiform mole, a disorder of fertilization, comprises complete and partial molar pregnancy. The pathologic and clinical features of complete and partial mole are well-described. Because of earlier diagnosis, however, the clinical presentation of complete molar pregnancy has significantly changed in recent years. The earlier diagnosis of complete mole is associated with more subtle pathologic findings than later molar pregnancy. The use of immunohistochemical techniques for the detection of maternally imprinted genes as ancillary testing in the diagnosis of complete and partial mole is therefore increasing. Although most molar pregnancies are sporadic, a familial syndrome of recurrent hydatidiform mole has been described. Further research will hopefully lead to identification of the gene defect responsible for this uncommon syndrome. Fortunately, patients with molar pregnancies can generally anticipate normal future reproduction. Close hCG follow-up after molar pregnancy is required to rule out development of postmolar gestational trophoblastic neoplasia. Recent studies suggest that a shorter period of postmolar follow-up may be reasonable for patients with both complete and partial molar pregnancy.

Abstract
This review summarizes the primary management of molar pregnancies, surveillance after evacuation, and the evaluation and management of malignant gestational trophoblastic neoplasia (GTN). Most women with gestational trophoblastic disease can be successfully managed with preservation of their normal reproductive function. It is important to manage molar pregnancies properly to minimize acute complications and identify malignant sequelae promptly. Current International Federation of Gynecology and Obstetrics (FIGO) guidelines for making the diagnosis and staging of GTN allow uniformity for reporting results of treatment. It is important to individualize treatment for women with malignant GTN based upon risk factors, using less toxic therapy for patients with low-risk disease and aggressive multiagent therapy for those with high-risk disease. Patients with malignant GTN should be managed in consultation with an individual experienced in the complex, multimodality treatment of these patients.

Abstract
OBJECTIVE We evaluated the risk of gestational trophoblastic neoplasia (GTN) for women with partial molar pregnancy whose human chorionic gonadotropin (hCG) levels fall spontaneously to undetectable levels using a sensitive hCG assay. METHODS We analyzed data from the New England Trophoblastic Disease Center to estimate the risk of GTN among 284 women with partial molar pregnancy and at least 6 months of gonadotropin follow-up. RESULTS None of the 238 women with complete gonadotropin follow-up and a spontaneous decline in serum hCG levels to undetectable levels subsequently developed GTN (95% confidence interval 0-1.6%). CONCLUSION If these results are replicated at other institutions with longstanding experience managing partial molar pregnancies, it may be reasonable to abbreviate clinical follow-up for women with partial molar pregnancy whose serum hCG levels spontaneously decline to an undetectable level.

Abstract
OBJECTIVE Human chorionic gonadotrophin (hCG) follow-up data were analysed retrospectively in all patients registered in the Hydatidiform Mole Registry at the Royal Women's Hospital, Melbourne from January 1992 to January 2001 to determine the risk of persistent trophoblast disease following partial molar pregnancy and to review the present follow-up protocol of patients suffering from partial hydatidiform molar pregnancy (PHM). METHODS Demographic factors were determined for all 344 cases with a review diagnosis of PHM, included age, history of previous hydatidiform mole, gestation length, hCG levels and compliance with follow-up. FINDINGS Six of the 344 patients diagnosed with PHM required treatment with single-agent methotrexate and folinic acid rescue. All six patients achieved and maintained a complete biochemical remission after chemotherapy. hCG regression assays were analysed for 235 patients: 225 patients had at least one normal hCG measurement during follow-up, of whom 152 (64.7%) patients obtained normal values within 2 months after evacuation. All patients obtained normal levels within 32 weeks after evacuation of the partial hydatidiform mole. Only 63 (25.6%) patients completed the recommended follow-up program. No patient who achieved normal hCG levels required chemotherapy because of a recurrent gestational trophoblastic tumour. RECOMMENDATIONS This study indicates that 1.7% of all partial mole pregnancy patients needed treatment for malignant sequelae. In contrast, no patient diagnosed with partial mole had a biochemical or clinical relapse after achieving normal levels of hCG, consistent with previous studies. Patients who have had a partial hydatidiform mole should be followed by hCG assays until normal levels are achieved and then follow-up can be safely discontinued.

Abstract
OBJECTIVE The aim of this study was to determine how often patients with complete hydatidiform mole (CHM) who spontaneously achieve normal human chorionic gonadotrophin (hCG) levels subsequently develop persistent or recurrent gestational trophoblast disease. METHODS Four hundred and fourteen cases of CHM registered at the Hydatidiform Mole Registry of Victoria were reviewed retrospectively after molar evacuation. Maternal age, gestational age, gravidity and parity were determined for each patient, as well as the need for chemotherapy. RESULTS Among the 414 patients, 55 (13.3%) required chemotherapy for persistent trophoblastic disease. None of the patients whose hCG levels spontaneously fell to normal subsequently developed persistent molar disease. CONCLUSION Weekly hCG measurements are recommended for all patients until normal levels are achieved. For patients who attain normal hCG levels within 2 months after evacuation, it seems safe to discontinue monitoring once normal levels are achieved. Patients who fail to achieve normal hCG levels by 2 months after evacuation should be monitored with monthly hCG measurements for 1 year after normalisation to assure sustained remission.

Abstract
Gestational trophoblastic disease (GTD) encompasses a unique group of uncommon but interrelated conditions derived from placental trophoblasts. For the purposes of discussion GTD is the appropriate collective name for hydatidiform mole, whereas the term gestational trophoblastic neoplasia (GTN) is reserved for cases with persistent human chorionic gonadotropin (hCG) titer elevation after evacuation of hydatidiform mole, metastatic disease, or choriocarcinoma. Although the pathology and clinical behavior of CM and PM are different, the initial management of both conditions is surgical evacuation by suction curettage, determination of the baseline, and follow-up with (hCG) titers. There are guidelines for risk-factor scoring and a staging system that classifies untreated patients into distinct prognostic categories so that treatment outcomes can be objectively compared. The rates of GTN and choriocarcinoma are decreasing and survival has dramatically improved.
