Background: Ectopic pregnancies, miscarriages and hydatidiform moles are the major types of pathological pregnancies in the early gestations of pregnancy and constitute an important public health problem. The trends and incidences of these pathological pregnancies may vary by ethnicity and geographical regions. This has not been fully investigated in the Chinese population. In this study we retrospectively report the trends of pathological pregnancies in Chinese population. Methods: Data on 22,511 women with ectopic pregnancy, hydatidiform mole and miscarriage were collected from the largest obstetrics and gynaecology hospital in China from 2003 to 2013. Data included age at diagnosis and the annual number of women with diagnosed ectopic pregnancy, hydatidiform mole and miscarriage. Results: The total number of ectopic pregnancy, hydatidiform mole and miscarriage was increased 3.5folds in 2013 compared to 2003. Ectopic pregnancy is the leading pathological pregnancy and miscarriage is increasing at a greater rate among the pathological pregnancies. The median age of women with hydatidiform mole at diagnosis significantly increased from 25.5 years to 29 years (p = 0.002), however the median age for other pathological pregnancies was not different between 2003 and 2013. The number of women with hydatidiform mole at diagnosis who were over 40 years old has increased. The mean maternal age is increased from 28.1 years old in 2003 to 29.4 years old in 2013 in this hospital. Conclusion: We speculate that the increased maternal age may contribute to the increase in these pathological pregnancies between 2003 and 2013 in China. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: We aim to explore if there are any other candidate genetic variants in patients with a history of at least one hydatidiform mole (HM) besides the well-known variants in NLRP7 and KHDC3L., Methods: The diagnosis of HM type was based on histopathology, and available HM tissues were collected for short tandem repeat (STR) genotyping to verify the diagnosis. DNA extracted from blood samples or decidual tissues of the 78 patients was subjected to whole-exome sequencing (WES)., Results: We identified five novel variants in NLRP7, two novel variants in KHDC3L, and a chromosome abnormality covering the KHDC3L locus among patients with HM. We found that patients with HM who carried heterozygous variants in KHDC3L had a chance of normal pregnancy. We also detected four novel genetic variants in candidate genes that may be associated with HM., Conclusion: Our study enriched the spectrum of variants in NLRP7 and KHDC3L in Chinese HM patients and provided a new outlook on the effects of heterozygous variants in KHDC3L. The novel candidate genetic variants associated with HMs reported in this study will also contribute to further research on HMs., (© 2022.

- Abstract
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 (χ
2 =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., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2022.

- Abstract
Background: Early detecting hydatidiform mole in missed abortion is challenge. In this retrospective observational study, we analysed the sensitivity of detecting hydatidiform mole by pre-evacuation ultrasound examination or naked eye after surgical uterine evacuation in missed abortion., Methods: Data on 577 cases with histologically confirmed hydatidiform mole were collected over a 10-year period and analysed. Data included serum β-hCG level before surgical evacuation, the ultrasound examination findings, histology findings and naked eye findings. In addition, serum β-hCG level on 2398 cases without hydatidiform mole was also collected., Results: The median maternal age was 29 (range, 17-53) years and the range of gestational age was 6 to 12 weeks. The sensitivity of detecting hydatidiform mole by ultrasound examination or by naked eye was 25% or 60% respectively. This sensitivity was not increased by the combination of ultrasound and naked eye. There was no difference in the sensitivity of detecting subtypes of hydatidiform mole. The higher β-hCG level was seen in cases with hydatidiform mole, compared to cases without hydatidiform mole. However, there was a lot of overlap in the distributions of β-hCG between the two groups., Conclusions: In this study, we found lower sensitivity of detecting hydatidiform mole by ultrasound in missed abortion. β-hCG level was higher in hydatidiform mole than in non- hydatidiform mole in missed abortion. Although higher sensitivity of detecting hydatidiform mole is seen by naked eye (60%), in order to minimise missed opportunity of detecting hydatidiform mole, our study suggests that routine histopathological examination is necessary in missed abortion.

- Abstract
Background: Pulmonary deportation of hydatidiform mole is an exceedingly rare entity. The underlying mechanisms and proper management strategies remain unclear based on sporadic case reports over the past six decades. This study aimed to investigate the clinical features and rational treatment of patients with benign molar pregnancies with pulmonary deportation based on our experience., Methods: Medical records of 20 cases of hydatidiform mole with pulmonary deportation were retrospectively reviewed at Peking Union Medical College Hospital from November 2006 to May 2019. The detailed information of all patients was recorded and analyzed. Patients were divided into different groups according to their characteristics and Mann-Whitney U test was used to compare the duration to achieve a normal β-human chorionic gonadotrophin (β-hCG) level after the first evacuation among groups., Results: Initial pulmonary computed tomography scans showed suspected bilateral, left and right chest deportation of hydatidiform mole in 12, four, and four patients, respectively, with the maximum nodular diameter ranging from 0.6 to 1.2 cm. Ten patients achieved lesion resolution while the remaining ten patients achieved decreases in the size of their pulmonary lesions. The median duration to achieve a normal β-hCG level after the first evacuation was 15.5 (13.0, 21.9) weeks. There was no significant difference in the duration to achieve a normal β-hCG level after the first evacuation between two groups based on age (≥40 years vs. < 40 years: 15.8 [12.2, 21.5] weeks vs. 15.5 [12.9, 23.0] weeks, Z = 0.094, P = 0.925), type of antecedent mole (partial mole vs. complete mole: 15.2 [12.5, 27.4] weeks vs. 15.9 [12.9, 21.5] weeks, Z = 0.165, P = 0.869), distribution of pulmonary nodules (bilateral lungs vs. unilateral lung: 15.2 [12.8, 22.5] weeks vs. 15.9 [13.2, 22.2] weeks, Z = 0.386, P = 0.700), maximum size of pulmonary nodules (>0.5 cm vs. ≤0.5 cm: 13.0 [11.3, 17.2] weeks vs. 16.0 [14.5, 23.8] weeks, Z = 1.815, P = 0.070), and number of uterine evacuations (once vs. twice or three times: 15.0 [13.0, 16.3] weeks vs. 16.0 [12.8, 23.9] weeks, Z = 0.832, P = 0.405). The post-molar cohort was followed up for 17 to 139 months, and no gestational trophoblastic neoplasia was observed., Conclusions: No surgeries other than uterine evacuation and no chemotherapy regimens are recommended for such patients if they achieve satisfactory decreases in the level of hCG and gradual decrease or disappearance of pulmonary deportation nodules. Patients should be informed about the necessity of long-term follow-up. More collaborative international studies on this exceedingly rare condition may guide decisions regarding optimal management strategies.

- Abstract
Objective: To evaluate the clinical characteristics and diagnostic strategies of early hydatidiform mole. Methods: A retrospective cohort study was conducted of 526 women with hydatidiform mole who underwent suction curettage and were confirmed by histopathology in Dalian Maternal and ChildHealth Care Hospital from Feb. 2013 to Feb. 2018, including 484 women with gestational age less than or equal to 12 weeks (the early group) and 42 women with gestational age greater than 12 weeks (the late group). The clinical characteristics between the two groups were compared, and the pathological diagnosis and pre-evacuation ultrasound examination of the early group were further discussed. Results: Compared with the late group, the clinical characteristics of the early group tended to be atypical, and the incidence of vaginal bleeding, excessive uterine size, theca lutein cysts (>6 cm) and pregnancy complications decreased significantly (all P< 0.05). The serum level of β-hCG in the early group was significantly lower than that in the late group ( Z=- 2.382, P= 0.017). While there was no significant difference in the pre-evacuation ultrasound detection rate between the two groups (53.5% vs 66.7%; χ(2)=2.697, P= 0.101). Five hundred and fifteen patients completed the follow-up, and 38 patients with post-mole neoplasia were all cured. There was no significant difference in the malignant transformation rate of hydatidiform mole between the two groups (7.0% vs 11.9%; χ(2)=0.745, P= 0.388). In the early group, 302 cases of complete hydatidiform mole (CHM), 179 cases of partial hydatidiform mole (PHM) and 3 cases of unclassified hydatidiform mole (UHM) were histologically diagnosed, according to pathological morphology combined with p57(KIP2) immunohistochemical staining. Compared with pathological diagnosis, the overall pre-evacuation ultrasound detection rate in the early hydatidiform mole was 53.5% (259/484), which was significantly better for complete (78.1%, 236/302) versus partial (11.7%, 21/179) hydatidiform moles (χ(2)=199.224, P< 0.01). There was significantly weak negative correlation between the overall ultrasound detection rate and gestational age of hydatidiform mole ( r =-0.211, P< 0.01). The gestational age of early PHM was significantly longer than that of CHM (68.0 vs 58.5 days; Z= -8.048, P< 0.01). Conclusions: The clinical presentations of early hydatidiform mole are not typical. Although ultrasound examination identifies only about half of hydatidiform moles, ultrasonography is still an important auxiliary examination method. Morphological examination combined with p57(K)IP2 immunohistochemical staining could effectively diagnose early hydatidiform mole, so as to reduce the missed diagnosis of hydatidiform mole.

- Abstract
Objective: To evacuate whether short-tandem-repeat (STR) DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles., Methods: 150 cases were selected based on histologic features that were previously diagnosed or suspected molar pregnancy. All sections were stained with hematoxylin as a quality control method, and guided the microscopic dissection. DNA was extracted from dissected chorionic villi and paired maternal endometrial FFPE tissue sections. Then, STR DNA genotyping was performed by AmpFlSTR(®) Sinofiler(TM) PCR Amplification system (Applied Biosystems, Inc). Data collection and analysis were carried out using GeneMapper(®) ID-X version 1.2 (Applied Biosystems, Inc)., Results: DNA genotyping was informative in all cases, leading to identification of 129 cases with abnormal genotype, including 95 complete and 34 partial moles, except 4 cases failed in PCR. Among 95 complete moles, 92 cases were monospermic and three were dispermic. Among 34 partial moles, 32 were dispermic and 2 were monospermic. The remaining 17 cases were balanced biallelic gestations., Conclusion: STR DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles. And in the absence of laser capture microdissection (LCM), hematoxylin staining plus manual dissection under microscopic guided is a more economic and practical method.
