Prevalence and management of ectopic and molar pregnancies in 17 countries in Africa and Latin America and the Caribbean: a secondary analysis of the WHO multi-country cross-sectional survey on abortion.

INTRODUCTION: There are limited global data on ectopic pregnancy (EP) and molar pregnancy (MP), making it important to understand their epidemiology and management across different regions. Our study aimed to describe their prevalence for both conditions, severity of their complications and management among women in selected health facilities across 17 countries in Africa and Latin America and the Caribbean (LAC). METHODS: This is a secondary analysis of the WHO multi-country survey on abortion. Data were collected from 280 healthcare facilities across 11 countries in Africa and 6 in LAC. Sociodemographic information, signs and symptoms, management and clinical outcomes were extracted from medical records. Facility-level data on post-abortion care (PAC) capabilities were also collected, and facilities were classified accordingly. χ2 or Fisher's exact tests were used to compare categorical data. RESULTS: The total number of women with EP and MP across both regions was 9.9% (2 415/24 424) where EP accounted for 7.8% (1 904/24 424) and MP for 2.1% (511/24 424). EP presented a higher severity of complications than MP. At admission, 49.8% of EP had signs of peritoneal irritation. The most common surgical management for EP was laparotomy (87.2%) and for MP, uterine evacuation (89.8%). Facilities with higher scores in infrastructure and capability to provide PAC more frequently provided minimal invasive management using methotrexate/other medical treatment (34.9%) and laparoscopy (5.1%). CONCLUSION: In Africa and LAC, EP and MP cause significant maternal morbidity and mortality. The disparity in the provision of good quality care highlights the need to strengthen the implementation of evidence-based recommendations in the clinical and surgical management of EP and MP.

Diagnosis and Management of Molar Pregnancies.

Complete and partial molar pregnancies arise from abnormal fertilization with marked proliferation of syncytiotrophoblasts. Earlier diagnosis has reduced the frequency of severe medical complications at presentation; however, the risk of progression to gestational trophoblastic neoplasia (GTN) has remained unchanged. Initial assessment should include serum hCG measurement after physical examination, laboratory testing for organ dysfunction, and Doppler ultrasound. Following uterine evacuation, pathologic assessment can distinguish complete from partial moles or non-molar gestations. Close surveillance is essential for the timely diagnosis of GTN. Cure rates and subsequent obstetrics outcomes are excellent, but all patients should be referred for psychologic support and expert level care.

Epidemiology of Gestational Trophoblastic Disease.

Worldwide incidence rates of gestational trophoblastic disease (GTD) are difficult to estimate and compare due to large methodological differences within and between countries. Asia has generally reported higher incidence rates than Europe and North America, but modern reports have demonstrated a temporal decrease of GTD incidence rates in Asia and an increase in some European countries and North America. The main risk factors for hydatidiform mole are maternal age and previous molar events. Future studies on the epidemiology of GTD should include gestational trophoblastic neoplasia and international collaborative studies on this rare disease should be encouraged.

Invasive and metastatic hydatidiform moles in Slovakia in 1993‒2022.

OBJECTIVE: A retrospective analysis of invasive and metastatic hydatidiform moles (HM) in the Slovak Republic (SR)‒epidemiology, patient characteristics and treatment outcomes. BACKROUND: Invasive and metastatic mole is a highly curable type of gestational trophoblastic neoplasia. Both invasive and metastatic HM may be cured by hysterectomy without adjuvant chemotherapy. METHODS: Nineteen cases of histopathologically confirmed HM (10 invasive and 9 metastatic) were treated in SR from 1993 to 2022. Patients were divided into two groups according to treatment modality (hysterectomy only ‒ 8; hysterectomy and chemotherapy ‒ 11). The parameters included in the analysis were patient age, antecedent pregnancy, human chorionic gonadotropin level, tumor size and time to remission. RESULTS: The incidence of invasive and metastatic HM in the SR was 1:121,253 pregnancies, or 1:86,589 live births. The overall cure rate was 100%, without recurrence. Hysterectomy was performed as first-line therapy in 14 patients, with a cure rate of 57.1%. 4 out of 8 patients (50%) with metastatic moles, who underwent first-line hysterectomy, were cured without chemotherapy. There was no statistically significant difference between the two groups in all selected parameters. CONCLUSION: First-line hysterectomy may lead to remission without adjuvant chemotherapy or reduce the number of chemotherapies in invasive and metastatic HM (Tab. 4, Fig. 2, Ref. 21).

Partial hydatidiform mole and coexisting fetus after frozen embryo transplantation: a case report.

Hydatidiform mole and coexisting fetus is a very rare condition of which etiology is still inconclusive. It may occur after assisted reproduction, often leading to the death of normal embryos and other serious complications. We report a case of partial hydatidiform mole and coexisting fetus after frozen embryo transplantation. More than two months after the patient underwent transplantation with two blastocysts (scored 4AB and 4BC), B-ultrasound showed a single live fetus with a large dense dotted strong echo area. The patient was treated with chemotherapy after the termination of pregnancy due to persistently increased human chorionic gonadotropin levels. Many studies have described trophoblast quality as a strong predictor of pregnancy. In the case in question, in addition to partial hydatidiform mole caused by multiple sperm entering the egg, we also speculate that the condition may be related to the poor quality of the trophoblastic ectoderm of the transferred embryo. In the process of assisted reproduction, the transfer of embryos with poor trophoblastic ectoderm in multiple embryo transfers may adversely affect pregnancy outcomes.

Gestational Trophoblastic Disease with Coexisting Progressing Pregnancy: Personalised Treatment Modalities.

Purpose: Gestational trophoblastic disease (GTD) coexisting with a steadily progressing pregnancy is an extremely rare condition presented in the literature as a single case or case series of successful delivery. The purpose of this study was to describe five cases of GTD and present possible management strategies for such patients. Methods: Clinical data of five pregnancies with coexisting GTD were identified within the Almazov National Medical Research Centre from 2018 to 2021. Results: Three cases of multiple pregnancies with complete hydatidiform moles and two cases of singleton pregnancies with intraplacental choriocarcinoma and invasive hydatidiform moles were identified. Three pregnancies were prolonged and ended with preterm deliveries. Malignant transformation of the GTD accounted for 60% of the cases. The condition of newborns was based on the level of prematurity and functional immaturity, and in all cases, it was aggravated by anemia. Conclusion: GTD coexisting with progressing pregnancy is threatened by the risks of preterm delivery, miscarriage, hemorrhage, and disease progression and requires monitoring in a multidisciplinary clinic experienced in the management of patients with malignant tumors during pregnancy. In cases of prolonged pregnancy against the background of GTD, we suggest the following monitoring during pregnancy: pelvic, abdominal ultrasound/MRI (without contrast), prenatal invasive fetal karyotype testing in cases of singleton pregnancy, lung X-ray/CT with uterine shielding, weekly assessment of ß-hCG levels, and dynamic monitoring of the fetus. The following postnatal monitoring should be performed: morphological examination of the placenta, weekly assessment of ß-hCG levels up to normalization, then monthly assessment up to six months, and control of ß-hCG level of the newborn.

Influence of COVID-19 pandemic on molar pregnancy and postmolar gestational trophoblastic neoplasia: An observational study.

OBJECTIVE: To assess whether the incidence and aggressiveness of molar pregnancy (MP) and postmolar gestational trophoblastic neoplasia (GTN) changed during the COVID-19 pandemic. DESIGN: Observational study with two separate designs: retrospective multicentre cohort of patients with MP/postmolar GTN and a cross-sectional analysis, with application of a questionnaire. SETTING: Six Brazilian Reference Centres on gestational trophoblastic disease. POPULATION: 2662 patients with MP/postmolar GTN treated from March-December/2015-2020 were retrospectively evaluated and 528 of these patients answered a questionnaire. METHODS: Longitudinal retrospective multicentre study of patients diagnosed with MP/ postmolar GTN at presentation and a cross-sectional analysis, with application of a questionnaire, exclusive to patients treated during the period of study, to assess living and health conditions during the COVID-19 pandemic compared with previous years. MAIN OUTCOME MEASURES: The incidence of MP/postmolar GTN. RESULTS: Compared with the last 5 pre-pandemic years, MP/postmolar GTN incidence remained stable during 2020 (COVID-19 pandemic). Multivariable logistic regression, adjusted for the patient age, showed that during 2020, presentation with MP was more likely to be >10 weeks of gestation (adjusted odds ratio [aOR] 2.50, 95% confidence interval [CI] 1.90-3.29, P < 0.001), have a pre-evacuation hCG level ≥100 000 iu/l (aOR 1.77, 95% CI 1.38-2.28, P < 0.001) and time to the initiation of chemotherapy ≥7 months (aOR 1.86, 95% CI 1.01-3.43, P = 0.047) when compared with 2015-2019. CONCLUSIONS: Although the incidence of MP/postmolar GTN remained stable during the COVID-19 pandemic in Brazil, the pandemic was associated with greater gestational age at MP diagnosis and more protracted delays in initiation of chemotherapy for postmolar GTN.

Advances in diagnostics and management of gestational trophoblastic disease.

BACKGROUND: Gestational trophoblastic disease (GTD) is a heterogeneous group of rare tumours characterised by abnormal proliferation of trophoblastic tissue. It consists of benign or premalignant conditions, such as complete and partial molar pregnancy and variants of malignant diseases. The malignant tumours specifically are commonly referred to as gestational trophoblastic neoplasia (GTN). They consist of invasive mole, choriocarcinoma, placental-site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT). CONCLUSIONS: Patients with GTD are often asymptomatic, although vaginal bleeding is a common presenting symptom. With the advances in ultrasound imaging in early pregnancy, the diagnosis of molar pregnancy is most commonly made in the first trimester of pregnancy. Sometimes, additional imaging such as chest X-ray, CT or MRI can help detect metastatic disease. Most women can be cured, and their reproductive function can be preserved. In this review, we focus on the advances in management strategies for gestational trophoblastic disease as well as possible future research directions.

Gestational trophoblastic disease- rare, sometimes dramatic, and what we know so far.

Gestational trophoblastic disease (GTD) is a heterogeneous group of lesions that are characterized by the abnormal proliferation of the trophoblast. Morphology, behavior and clinical significance vary tremendously and range from benign, non-neoplastic lesions that cause sometimes dysfunctional uterine bleeding to aggressive, highly, malignant tumors. The recently updated 2020 World Health Organization (WHO) Classification of Female Genital Tumors divides GTD in molar pregnancies/ hydatidiform moles, gestational trophoblastic neoplasms, tumor-like lesions and abnormal (nonmolar) villous lesions. In this article we review the typical clinical presentations of GTDs, their histopathologic features, contributing immunohistochemical stains and current diagnostic criteria. We discuss novel insights in the proposed pathogenesis, newly proposed entities and advances in ancillary diagnostic techniques and their relevance to the histopathologic diagnosis of GTD. Additionally we briefly review current treatment options, prognosis and prognostic factors of GTDs.

Experience of women on the Irish National Gestational Trophoblastic Disease Registry.

OBJECTIVE: Gestational Trophoblastic Disease (GTD) is a rare pregnancy related disorder and the most curable of all gynaecological malignancies. GTD comprises the premalignant conditions of complete or partial hydatidiform mole known as molar pregnancy and a spectrum of malignant disorders termed gestational trophoblastic neoplasia. Clinical management and treatment in specialist centres is essential to achieve high cure rates and clinical guidelines recommend registration with a GTD centre as a minimum standard of care. National GTD registries are valuable repositories of epidemiological data and facilitate clinical audit, centralised pathology review and human chorionic gonadotropin (hCG) monitoring. This study sought the opinion of women enrolled on the Irish National GTD registry to inform future service development and establish a knowledge base for molar pregnancy in Ireland. STUDY DESIGN: A cross-sectional survey using an anonymised questionnaire was distributed by post to all women on the GTD registry. The questionnaire was designed by a multidisciplinary team and consisted of twenty-five closed-ended questions and two open-ended questions to facilitate feedback. Data collected in the survey included information on the patient experience of registration, knowledge of molar pregnancy, diagnosis at their local hospital, hCG monitoring and overall satisfaction with the service. RESULTS: The survey had a successful participation rate of 42.6% (215/504). Forty-nine percent (n = 106) of respondents rated a rapid hCG result as their top priority. Forty percent (n = 84) of women had concerns about future pregnancies but acknowledged that these were largely addressed by the GTD specialist nurses. A quarter of respondents reported that other medical professionals with whom they interacted during follow-up treatment did not understand their condition. Many women commented on the emotional stress of attending their local maternity unit for phlebotomy while dealing with pregnancy loss. CONCLUSION: This study is unique in being the first survey of women on the Irish National GTD registry. It highlights the specific needs of women with molar pregnancy in terms of psychological support, bereavement counselling and peer support groups. It reveals a knowledge gap in molar pregnancy amongst healthcare professionals which should be considered in future planning of medical and nursing curricula.

[Hyperthyroidism and an unexpected molar pregnancy]. / Hyperthyreoïdie en een onverwachte molazwangerschap.

BACKGROUND: A molar pregnancy is a rare complication of (non-viable) pregnancy and produces high levels of hCG-hormone. hCG has characteristics similar to TSH, and therefore (severe) hyperthyroidism can occur. The incidence of molar pregnancy is approximately 1 in 1000-1500 pregnancies. CASE DESCRIPTION: A 23-year-old woman had complaints of discomfort, nausea and vomiting. A urine pregnancy test was negative and laboratory tests showed a severe hyperthyroidism. After referral a molar pregnancy was diagnosed (hCG 1.7 million IU/L). She was treated by curettage. hCG levels insufficiently decreased in the following weeks, and gestational trophoblastic neoplasia was diagnosed. She needed several courses of methotrexate after which she completely recovered. CONCLUSION: Severe hyperthyreoidism can be caused by a molar pregnancy. A urine pregnancy test can be negative because of too high hCG-levels, also known as the hook effect. Early recognition and treatment are very important because of the risk of severe complications.

Centralized surveillance of hydatidiform mole: 7-year experience from a regional hospital in China.

OBJECTIVE: To assess the strategy and value of centralized surveillance of hydatidiform mole at a regional hospital in China and to investigate the necessity of prophylactic chemotherapy for high-risk complete hydatidiform mole. METHODS: Between February 2013 and February 2020, all women with hydatidiform mole in Dalian Women's and Children's Medical Center (Group) were registered for surveillance and treatment when indicated. Women with complete hydatidiform mole were categorized into low-risk and high-risk groups according to the criteria from Song Hongzhao's trophoblastic neoplasia. Outcomes and treatments were analyzed retrospectively. RESULTS: In total, 703 women with hydatidiform mole were registered for surveillance with a follow-up rate of 97.9% (688/703). 680 women were enrolled and 52 (7.6%) developed post-molar gestational trophoblastic neoplasia, all with low-risk International Federation of Gynecology and Obstetrics (FIGO) scores 0-5. Post-molar gestational trophoblastic neoplasia was diagnosed in 12.3% (51/413) of patients with complete hydatidiform moles and 0.4% (1/263) of patients were diagnosed with partial hydatidiform moles (χ2=32.415, p<0.001). Post-molar gestational trophoblastic neoplasia was diagnosed in 27.7% (28/101) of the high-risk complete hydatidiform mole group and in 7.4% (23/312) of the low-risk complete hydatidiform mole group (χ2=29.196, p<0.001). No difference in the pre-treatment assessments of patients with post-molar gestational trophoblastic neoplasia was found between the low-risk and high-risk complete hydatidiform mole groups (all p>0.05). All 52 patients with post-molar gestational trophoblastic neoplasia were cured, with a complete response rate of 61.2% (30/49) with first-line single-agent chemotherapy. CONCLUSIONS: A centralized hydatidiform mole surveillance program is feasible and effective and may improve the prognosis of patients with post-molar gestational trophoblastic neoplasia. Prophylactic chemotherapy is not recommended for women with high-risk complete hydatidiform mole with adequate surveillance.

The current situation of health services for hydatidiform mole in Cambodia.

AIM: Management of hydatidiform mole is important to reduce the mortality and morbidity of choriocarcinoma. This study aims to understand the existing health services for hydatidiform mole and to estimate the incidence of gestational trophoblastic disease (GTD) in Cambodia. METHODS: A questionnaire was used to collect information on the existing health services for pregnancy and hydatidiform mole at health facilities from attendants of the 16th Annual Conference of the Cambodian Society of Gynecology and Obstetrics in 2017. The incidence of GTD in 2014-2017 was estimated using Health Information System data. RESULTS: A total of 126 attendants, who were from all provinces except three provinces, answered the questionnaire. The work places were national hospitals (n = 29), provincial hospitals (n = 42), district hospitals (n = 20), health centers (n = 6), and others (n = 29). The answers of participants from the public sector suggested the following: Ultrasonography is available at all hospitals but not health centers; Human chorionic gonadotropin (hCG) measurement is only available at national hospitals; Treatment of hydatidiform mole is performed at national hospitals and provincial hospitals; and Treatment of gestational trophoblastic neoplasia (GTN) is provided at national hospitals. The incidence of hydatidiform mole and GTN at health facilities in the public sector in 2014-2017 was 0.95 per 1000 deliveries and 6.58 per 100 000 deliveries, respectively. CONCLUSIONS: The results suggest that provincial hospitals are important to detect suspected invasive mole and refer to national hospitals for diagnosis and treatment. Further studies on the management of GTD and development of the guidelines of GTD are needed.

Gestational trophoblastic neoplasia after human chorionic gonadotropin normalization in a retrospective cohort of 7761 patients in France.

BACKGROUND: The risk of malignant transformation of molar pregnancies after human chorionic gonadotropin levels return to normal is low, roughly 0.4%, but may justify an adaptation of monitoring strategies for certain patients. OBJECTIVE: This study aimed to determine the risk of gestational trophoblastic neoplasia after human chorionic gonadotropin normalization in women with molar pregnancy and identify risk factors for this type of malignant transformation to optimize follow-up protocols after human chorionic gonadotropin normalization. STUDY DESIGN: This was a retrospective observational national cohort study based at the French National Center for Trophoblastic Diseases of 7761 patients, treated between 1999 and 2020 for gestational trophoblastic disease, whose human chorionic gonadotropin levels returned spontaneously to normal. RESULTS: Among 7761 patients whose human chorionic gonadotropin levels returned to normal, 20 (0.26%) developed gestational trophoblastic neoplasia. The risk of malignant transformation varied with the type of mole, from 0% (0 of 2592 cases) for histologically proven partial mole to 0.36% for complete mole (18 of 5045) and 2.1% (2 of 95) for twin molar pregnancy. The median time to diagnosis of malignant transformation after human chorionic gonadotropin normalization was 11.4 months (range, 1-34 months). At diagnosis, 16 of 20 patients (80%) had the International Federation of Gynecology and Obstetrics stage I tumor, and 10 of 20 patients (50%) had a tumor classified as low risk in terms of the International Federation of Gynecology and Obstetrics score. In 9 of 20 patients (45%), the most common first-line treatment was combination chemotherapy. A quarter of these tumors (5 of 20) were histologically proven placental site or epithelioid trophoblastic tumors. In univariate analysis, the factors significantly associated with a higher risk of developing gestational trophoblastic neoplasia after the end of the normal human chorionic gonadotropin monitoring period were age of ≥45 years (odds ratio, 8.3; 95% confidence interval, 2.0-32.7; P=.004) and time to human chorionic gonadotropin normalization of ≥8 weeks (odds ratio, 7.7; 95% confidence interval, 1.1-335; P=.03). The risk was even higher for human chorionic gonadotropin normalization times of ≥17 weeks (odds ratio, 19.5; 95% confidence interval, 3.3-206; P<.001). CONCLUSION: In this group of patients with gestational trophoblastic disease, none of the those with pathologically verified partial mole had malignant transformation, supporting the current recommendation of stopping human chorionic gonadotropin monitoring after 3 successive negative tests. In cases of complete mole or twin molar pregnancy, we proposed to extend the monitoring period with quarterly human chorionic gonadotropin measurements for an additional 30 months in patients with the identified risk factors for late malignant transformation (age, ≥45 years; time to human chorionic gonadotropin normalization, ≥8 weeks).

Fertility and pregnancy outcome in gestational trophoblastic disease.

The aim of this review is to provide an overview of existing literature and current knowledge on fertility rates and reproductive outcomes after gestational trophoblastic disease. A systematic literature search was performed to retrieve all available studies on fertility rates and reproductive outcomes after hydatidiform mole pregnancy, low-risk gestational trophoblastic neoplasia, high- and ultra-high-risk gestational trophoblastic neoplasia, and the rare placental site trophoblastic tumor and epithelioid trophoblastic tumor forms of gestational trophoblastic neoplasia. The effects of single-agent chemotherapy, multi-agent including high-dose chemotherapy, and immunotherapy on fertility, pregnancy wish, and pregnancy outcomes were evaluated and summarized. After treatment for gestational trophoblastic neoplasia, most, but not all, women want to achieve another pregnancy. Age and extent of therapy determine if there is a risk of loss of fertility. Single-agent treatment does not affect fertility and subsequent pregnancy outcome. Miscarriage occurs more often in women who conceive within 6 months of follow-up after chemotherapy. Multi-agent chemotherapy hastens the natural menopause by three years and commonly induces a temporary amenorrhea, but in young women rarely causes permanent ovarian failure or infertility. Subsequent pregnancies have a high chance of ending with live healthy babies. In contrast, high-dose chemotherapy typically induces permanent amenorrhea, and no pregnancies have been reported after high-dose chemotherapy for gestational trophoblastic neoplasia. Immunotherapy is promising and may give better outcomes than multiple schedules of chemotherapy or even high-dose chemotherapy. The first pregnancy after immunotherapy has recently been described. Data on fertility-sparing treatment in placental site trophoblastic tumor and epithelioid trophoblastic tumor are still scarce, and this option should be offered with caution. In general, patients with gestational trophoblastic neoplasia may be reassured about their future fertility and pregnancy outcome. Detailed registration of high-risk gestational trophoblastic neoplasia is still indispensable to obtain more complete data to better inform patients in the future.

Recurrent GTD and GTD coexisting with normal twin pregnancy.

Hydatidiform mole (HM) affects around 1/1000 pregnancies, and in such cases the recurrence risk is around 1%, being greater for those with complete HM (CHM). Whilst most cases appear sporadic with unknown mechanisms, there is a distinct subgroup of patients who suffer recurrent pregnancy loss, including multiple recurrent CHM (familial recurrent biparental HM syndrome). The majority of these cases are related to maternal genetic mutations in genes related to the control of imprinting, specifically NALP7 and KHDC3L. Oocyte donation is an effective treatment allowing these patients to have successful pregnancies. Approximately 1 in 50,000 pregnancies are complicated by twin pregnancy comprising normal foetus and HM, the majority of reported cases being CHM. Such pregnancies are at significantly increased risk of complications, including pregnancy loss, early-onset preeclampsia and severe preterm delivery, but when managed conservatively the delivery of a liveborn healthy infant occurs in around one-third of cases. Regardless of management, the risk of persistent GTD in such cases appears similar to that following singleton CHM. Rarely, other conditions mimic prenatal ultrasound appearances of twin pregnancy with HM, CHM mosaicism and placental mesenchymal dysplasia, both of which have distinctive histological and genetic features.

A molar pregnancy in an embryo donor cow.

A 6-year-old Hereford embryo donor cow was referred to Auburn University College of Veterinary Medicine for a mass in the tip of her left uterine horn. The cow had recently undergone an embryo collection which yielded unfertilized, degenerated ova. Transrectal palpation and ultrasound revealed a multi-locular mass enveloped by two separate compartments that resembled an amniotic and allantoic cavity within the uterus. Tissue was collected via a uterine flush and submitted for histopathology. The tissue was determined to be placenta, confirming the diagnosis of a molar pregnancy. Following treatment, the cow was able to produce numerous viable embryos. Molar pregnancies are rare and characterized by abnormal growth of trophoblastic cells leading to formation of intrauterine cystic masses. It is important to routinely perform an ultrasonographic examination of the cow's reproductive tract approximately 30 days following non-surgical in vivo embryo collections to detect and treat unwanted conditions such as pregnancy and cystic conditions.

The management of hydatidiform mole using prophylactic chemotherapy and hysterectomy for high-risk patients decreased the incidence of gestational trophoblastic neoplasia in Vietnam: a retrospective observational study.

The management of hydatidiform mole (HM) and the incidence of post-molar gestational trophoblastic neoplasia (GTN) in Vietnam has not been reported to date. This study aimed to study the incidence of HM and post-molar GTN and identify factors associated with post-molar GTN at a tertiary hospital in Vietnam. Five hundred and eighty-four patients who were treated for HM at Tu Du Hospital between January and December 2010 were included in this study. The mean age and gestational age at the first evacuation were 28.8 years old and 11.0 weeks, respectively. After the initial evacuation and pathological examination, 87 patients who were older than 40 or did not wish to have children underwent a hysterectomy, while the others underwent second curettage. All 472 patients who had human chorionic gonadotropin (hCG) ≥ 100,000 IU/L before treatment received one cycle of methotrexate with folinic acid as prophylactic chemotherapy. The incidence of HM was 11.1 per 1,000 deliveries; 47 patients (8.0%) developed post-molar GTN. Gestational week, hCG level at one week after the first evacuation, and pathological remnants were significantly associated with the development of post-molar GTN. The results of this study suggest that prophylactic chemotherapy and hysterectomy may be useful for high-risk HM patients to reduce post-molar GTN in settings in which the risk of post-molar GTN and loss to follow-up after HM are greater and hCG measurements and appropriate GTN treatments are unavailable. However, future studies on the long-term outcomes and side effects of prophylactic therapies on HM are required.

Successful Management of the First Case of a Metastasized Complete Mole in Form of Twin Pregnancy in Jordan.

BACKGROUND A complete mole with a living fetus in a form of twin pregnancy that is a rare obstetric event. The development of metastatic gestational trophoblastic disease is the most important and serious complication. It is debatable whether to terminate the pregnancy or to continue. Another point is the validity of the conservative treatment of this type of neoplasm, especially in developing countries. CASE REPORT In this study, we report the first case of a twin pregnancy with complete mole and a living fetus in Jordan, which is a developing country. A 33-year-old woman presented with vaginal bleeding which was revealed to be due to a complete mole in the form of a twin pregnancy. A hystrostomy was performed with subsequent drop of ß-hCG level. However, the ß-hCG started to rise and the CT scan revealed multiple metastatic sites. Accordingly, she received 3 cycles of methotrexate, with a subsequent reduction in ß-hCG level. CONCLUSIONS This is the first case report of a complete mole in twin pregnancy in Jordan. To overcome the development of metastasis, close follow-up and immediate treatment are crucial when the conservative approach is being considered. This report highlights the importance of considering the diagnosis of complete mole for women with twin and vaginal bleeding.
