Serum hCG levels in the prediction of molar pregnancy below 11 weeks of gestational age.

Objective: The aim of this study was to evaluate the serum hCG level in the differential diagnosis between non-molar miscarriage and complete hydatidiform mole in<11 weeks gestation.

Methods: This was a retrospective collaborative cohort study. This study included women with gestational age<11 weeks, with ultrasound evidence of failed pregnancy and available serum hCG pre-uterine evacuation, divided into two groups: the non-molar miscarriage group and the complete hydatidiform mole group.

Outcomes of patients registered with the Queensland Trophoblast Centre diagnosed with gestational trophoblastic neoplasia who develop resistance to chemotherapy.

Objectives: To audit outcomes of patients registered in the Queensland Trophoblast Centre (QTC) database who develop resistance to primary chemotherapy. To determine any risk factors that may predict first-line chemotherapy resistance in patients diagnosed with gestational trophoblastic neoplasia (GTN).

Methods: Patients within the QTC who were diagnosed with GTN between January 2012 and December 2020 were reviewed.

Hysteroscopy improves surgical outcomes of hydatidiform moles while reducing postoperative residuals.

Objective: To evaluate the clinical efficacy of hysteroscopy in the treatment of molar pregnancy and postoperative residual tissue.

Methods: This retrospective study involved 68 patients who underwent treatment for molar pregnancy in Shanxi Children's Hospital Shanxi Maternal and Child Health Hospital from April 2020 to May 2022. Based on intervention methods, patients were divided into a conventional group (n=33) and a hysteroscopy group (n=35).

Gestational trophoblastic neoplasm: Patient outcomes and clinical pearls from a multidisciplinary referral center.

Objectives: To describe clinical outcomes and pearls for patients with gestational trophoblastic neoplasm (GTN).

Methods: Patients with GTN treated at a referral center from 1/2006 to 12/2022 were included. Clinical characteristics, World Health Organization risk score (low-risk 0-6, high-risk ≥7), and treatments/outcomes were evaluated using summary statistics, stratified by initial treatment at a referral center versus locally.

Vaginal metastasis in gestational trophoblastic neoplasia: Experience from Sheffield trophoblastic disease Centre and recommendations for management.

Introduction: Gestational trophoblastic neoplasia (GTN) is rare in the UK, with an estimated incidence of one in 50,000 live births. Cases of vaginal metastasis are even rarer, with only eight case series reporting 187 cases over the past 40 years. Management recommendations in the literature are scarce despite the potential risk of massive, potentially life-threatening vaginal haemorrhage.

Diploid fetus with partially triploid placenta: case presentation and management strategy.

Multiple placental cysts are a common finding in obstetric ultrasound imaging. Although they have benign differential diagnoses, such as hydropic degeneration of the placenta or placental mesenchymal dysplasia, it's important to consider significant pathologies, such as benign gestational trophoblastic disease or hydatidiform mole. A challenging issue in obstetrics is pregnancies with a placenta that has a bipartite texture.

Complete mole coexisting with a normal fetus in a dichorionic diamniotic pregnancy: a case report.

Introduction: A molar pregnancy coexisting with a normal fetus is a very rare occurrence. It can present as a complete mole with a normal fetus or a partial mole with a normal fetus. There is paucity of data on optimal management of such patients who have this presentation, which mostly ends with a poor prognosis.

Defects in meiosis I contribute to the genesis of androgenetic hydatidiform moles.

To identify novel genes responsible for recurrent hydatidiform moles (HMs), we performed exome sequencing on 75 unrelated patients who were negative for mutations in the known genes. We identified biallelic deleterious variants in 6 genes, FOXL2, MAJIN, KASH5, SYCP2, MEIOB, and HFM1, in patients with androgenetic HMs, including a familial case of 3 affected members. Five of these genes are essential for meiosis I, and their deficiencies lead to premature ovarian insufficiency.

The role of single-dose prophylactic methotrexate in the prevention of post-molar gestational trophoblastic neoplasia in patients with high-risk molar pregnancy.

Introduction: Prophylactic chemotherapy (PC) has been suggested to be effective in prevention of post molar gestational trophoblastic neoplasia (PGTN) in patients with high-risk molar pregnancies. The goal of this study is to assess the efficacy of single dose methotrexate as PC in terms of spontaneous remission, time to remission, and progression to PGTN.

Materials And Methods: Patients with molar pregnancy were recruited to the study and underwent cervical dilation and suction curettage.

Trisomy 16 mimicking hydatidiform mole.

The authors present a case of 1st trimester miscarriage where an early, complete hydatidiform mole was clinically suspected. Histopathological and immunohistochemical analyses excluded a complete mole, but the histomorphological profile was in concordance with a partial hydatidiform mole. Genetic analysis excluded a partial mole based on biparental genome composition, where further genetic analyses detected trisomy of chromosome 16.

Concurrent High-Grade Serous Carcinoma with Mucinous Differentiation and Ectopic Complete Molar Pregnancy of the Fallopian Tube: A Case Report.

Objective: We report the first documented case of concurrent ectopic complete hydatidiform mole (CHM) and high-grade serous carcinoma (HGSC) of the fallopian tube, associated with unique histologic features and mutations in the HGSC.

Case Report: The patient presented with pelvic pain and vaginal bleeding. Laboratory examination revealed a positive urine pregnancy test and high serum beta-human chorionic gonadotropin (β-hCG).

Complete Hydatidiform Mole with Twin Live Fetuses in a Triplet Pregnancy: A Case Report and Literature Review.

Introduction: The coexistence of a complete hydatidiform mole with twin live fetuses in a triplet pregnancy is an extremely rare condition with an unknown incidence.

Case Report: This report presents a case of a dichorionic diamniotic triplet pregnancy complicated by the coexistence of a complete hydatidiform mole and twin live fetuses. The pregnancy resulted in a preterm delivery at 30 weeks and 5 days of gestation, with both live fetuses surviving to date.

Association of gestational trophoblastic disease with subsequent development of non-trophoblastic cancer.

Objective: To evaluate the association between gestational trophoblastic disease and the subsequent risk of developing non-trophoblastic cancer.

Methods: We conducted a retrospective cohort study of 3084 women with gestational trophoblastic disease and 1 415 812 women with obstetric deliveries in Quebec, Canada, between 1989 and 2021. The main exposure was gestational trophoblastic disease, including hydatidiform moles, invasive moles, and gestational choriocarcinoma.

Trophoblastic disease and choriocarcinoma.

Gestational trophoblastic disease (GTD) is a group of diseases associated with pregnancies that demonstrate abnormal development of trophoblastic cells. GTD includes hydatidiform moles (HM) that may continue to further develop into gestational trophoblastic neoplasms (GTN), such as choriocarcinoma (CC). Gestational CC is a malignant mass development that may arise from HM, from other (normal) pregnancies or from other gestational events (such as ectopic pregnancies).

The causal relationship between hydatidiform mole and nutrients: A two-sample Mendelian randomization study.

Background: Hydatidiform mole (HM), a subset of gestational trophoblastic disease, is considered precancerous and exhibits geographical variation. The incidence of HM is linked to nutritional factors. This study aimed to investigate the causal relationship between nutrients and HM using a bidirectional two-sample Mendelian randomization (MR) approach.

Genetics and Genomics of Gestational Trophoblastic Disease.

This article focuses on hydatidiform mole (HM), which is the most common form of gestational trophoblastic disease and the most studied at the genomic and genetic levels. We summarize current laboratory methods to diagnose HM, discuss their limitations and advantages, and share the lessons we have learned. We also provide an overview of the history of recurrent HM, their known genetic etiologies, and the mechanisms of their formation.

Pathology of Gestational Trophoblastic Disease (GTD).

Gestational trophoblastic disease (GTD), comprising hydatidiform moles (HM) and gestational trophoblastic tumors (GTT), is extremely rare. HM originate from villous trophoblast and are considered preneoplastic. GTT originate from the intermediate, largely extravillous trophoblast and includes choriocarcinoma, placental site trophoblastic tumor, epitheloid trophoblastic tumor, and mixed trophoblastic tumor.
