Abstract
To retrospectively analyze the fertility outcomes and prognosis of gestational trophoblastic disease (GTD) patients, providing a basis for targeted fertility guidance and counseling. 82 GTD patients of childbearing age who received treatment at the Obstetrics and Gynecology Department of Lanzhou University First Hospital from January 2016 to January 2023 were stratified into re-pregnancy (n = 20) and non-re-pregnancy (n = 33) cohorts based on their pregnancy outcomes. The impacts of various factors on pregnancy outcomes were subsequently evaluated, encompassing the rates of subsequent pregnancies, live births, miscarriages, ectopic pregnancies, and ongoing pregnancies. Finally, logistics regression model was employed to analyze the risk factors affecting re-pregnancy in GTD patients. The study delineated those patients with different GTD pathologies had varying re-pregnancy rates (mole, erosive mole and choriocarcinoma accounted for 66.04%, 30.19% and 3.77%, respectively). Treatment predominantly involved uterine curettage, with fewer cases receiving chemotherapy alone or in conjunction with curettage accounted for 67.92%, 5.66%, and 26.42%, respectively. The average chemotherapy frequency was 4.59 ± 2.43 sessions, and a majority sought reproductive counseling. Re-pregnancy occurred in 37.74% of patients. The live birth rate was 65.00%, with miscarriage and ectopic pregnancy rates at 25.00% and 5.00% respectively. Logistic regression analysis pinpointed the absence of pre-pregnancy counseling as a significant independent risk factor for re-pregnancy in GTD patients (p < 0.05). While chemotherapy may influence ovarian function, with the majority of patients desiring children post-recovery, pregnancy rates remain high. Fertility counseling significantly enhances re-pregnancy success rates in GTD survivors, emphasizing its recommendation for those aiming to conceive post-recovery.

Abstract
Background Minimal studies have been carried out on a partial hydatidiform mole (PHM) in Vietnam, so the treatment outcomes for patients with PHM are unknown. This study aimed to determine the occurrence rate of gestational trophoblastic neoplasia (GTN) and its related factors in women with PHM at Tu Du Hospital, Vietnam. Materials and methods This retrospective cohort study included 370 women with PHM diagnosed through a histopathological assessment following termination of pregnancy at Tu Du Hospital from January 2020 to December 2021. Survival analysis was used for GTN cumulative rate estimation and the Cox regression model for determining GTN-related factors. Results After a 1-year follow-up, 21 patients were found to have GTN, exhibiting a rate of 5.7% (95% confidence interval (CI): 3.5 - 8.4). GTN occurred 4.67±2.23 weeks following curettage with peaks at weeks 3-6. No cases of GTN were recorded eight weeks following termination by curettage. After multivariate analysis, the GTN rate was higher in patients with a history of miscarriage/termination (hazard ratio (HR)=2.84; 95% CI: 1.05-7.69). Conclusion The rate of GTN in PHM patients was 5.7%. Patients who had a history of miscarriage or termination were 2.84 times more likely to develop GTN than patients who did not.

Abstract
BACKGROUND Gestational Trophoblastic Neoplasia (GTN) is a disease of the reproductive age group with an incidence rate of <1% among all tumors involving the female reproductive tract. It occurs because of aberrant fertilization. Patients are diagnosed early because of aggravated symptoms during pregnancy. Moreover, patients also bleed from the tumor sites, which leads to early presentation. A cure rate of 100% can be achieved with adequate treatment. MAIN BODY In this literature review, the authors have brought to attention the risk factors, classification, and various treatment options in GTN patients according to their stratification as per the WHO scoring system. Patients are categorized into low and high risk based on the FIGO scoring system. Patients with low risk are treated with single-agent methotrexate or actinomycin-D. Despite the superiority of actinomycin-D in terms of efficacy, methotrexate remains the first choice of therapy in low-risk patients due to its better toxicity profile. Multi-agent chemotherapy with etoposide, methotrexate, actinomycin-D, cyclophosphamide and vincristine (EMA-CO) leads to complete remission in 93% of high-risk GTN patients. Around 40% of patients with incomplete responses are salvaged with platinum-based multi-agent chemotherapy. Isolated chemo-resistant clones can be salvaged with surgical interventions. CONCLUSION The mortality in patients with GTN has significantly reduced over time. With adequate multi-disciplinary support, patients with GTN can ultimately be cured and can spend every day healthy reproductive life.

Abstract
Abstract
Background
Invasive mole is a trophoblastic disease (GTD) caused by trophoblast cells invading the myometrium during pregnancy. The GTD range also includes mole hydatidiform, choriocarcinoma, and placental site trophoblastic tumor (PSTT). Invasive moles are most common following molar pregnancies; however, they can even rarely occur after a full-term birth. Despite the fact that pathology is the only way to make a clear diagnosis, clinic and radiologic evaluation can be helpful. We wanted to highlight a rare incidence of invasive mole following a healthy full-term delivery in this case.
Case presentation
A 28-year-old female patient presented with intermittent prolonged severe vaginal bleeding for 2 weeks after a term healthy vaginal delivery. In workup, beta human chorionic gonadotropin levels (b-hCG) value was 7540 mIU/ml. After suspicion of gestational trophoblastic neoplasm (GTN), the patient was sent to ultrasonography (US) and magnetic resonance imaging (MRI). GTN was confirmed by radiological and clinical findings, and a conclusive diagnosis of an invasive mole was made histopathologically.
Conclusion
Invasive mole should be considered in the differential diagnosis in patients with postpartum bleeding and a persistently high b-hCG level after a healthy term delivery.

Abstract
Abstract
Blastocyst implantation and neoplastic invasion have some common properties related to tissue invasion, mediated by various cytokines.
Aim
To compare the expression of IL-6, STAT-3 and telomerase in material of abortions in the first trimester of pregnancy, at term placentas and in choriocarcinomas.
Methods
Immunohistochemical reactions were performed on formalin fixed and included in paraffin samples from 3 groups: abortions, normal at term placentas and choriocarcinomas. Western Blot and Real-Time PCR assays were performed on fresh material from BeWo cell line and in primary culture cells of normal placenta.
Results
Immunohistochemical reactions: IL-6 expression was moderate in the first trimester abortion samples and high in at term placentas and choriocarcinomas. STAT-3 was strongly positive in all groups. Telomerase expression was absent in normal at term placentas but was increased in BeWo cells.
Conclusion
IL-6 and STAT-3 are present in the invasion process of the normal placental development and they are maintained during the malignant transformation to choriocarcinoma. The intense telomerase expression observed in BeWo cells was strongly associated with the malignant phenotype, confirming it as a good marker for cell transformation and tumor progression.

Abstract
Gestational trophoblastic disease (GTD) is an unusual disease occurring in pregnancy that originates from abnormal trophoblastic cells and comprises a group of diseases with different properties of invasion, metastasis and recurrence. The GTD group includes hydatidiform moles and gestational trophoblastic neoplasms (GTNs), with GTNs being divided into invasive moles, choriocarcinoma, placental site trophoblastic tumors and epithelioid trophoblastic tumors. The present review focuses on current effective treatments for GTD, including conventional and novel promising direct enzyme prodrug therapies (DEPTs). Conventional therapies, such as chemotherapy and hysterectomy, are currently used in a clinical setting; however, the use of diverse DEPTs, including antibody-DEPT and gene-DEPT is also being attempted to cure GTNs. In addition, gene delivery tools using genetically engineered neural stem cells (NSCs) are presently being examined for the treatment of GTNs. The tumor-tropism of NSCs by chemoattractant factors is a unique characteristic of these cells and can serve as a vehicle to deliver anticancer agents. Previous studies have demonstrated that injection with NSC-expressing suicide genes into xenograft animal models has a significant inhibitory effect on tumor growth. Stem cells can be genetically engineered to express anticancer genes, which migrate to the metastatic sites and selectively target cancer cells, and are considered to effectively target metastatic GTNs. However, the safety issue of stem cell therapy, such as tumorigenesis, remains a challenge. Novel therapies comprising a combination of conventional and novel promising treatments are anticipated to be definitive treatments for metastasized and/or recurrent patients with GTNs.

Abstract
Uterine natural killer (uNK) cells have been hypothesized to serve a role in controlling trophoblast invasion and proliferation. The aim of the present study was to identify the distribution and number of uNK cells in normal pregnancy (NP), partial mole (PM), complete mole (CM) and invasive mole (IM). uNK cells were detected using dolichos biflorus agglutinin lectin immunohistochemistry in decidual and villous tissues from early NP (n=15), late NP (n=15), PM (n=22), CM (n=20) and IM (n=10). A scaled eye piece was used for cell counting to obtain semi-quantitative results. It was revealed that uNK cells were mainly located in the uterine deciduas of early NP. As pregnancy progressed, the number of decidual uNK cells significantly decreased. Decidual uNK cells of PM, CM and IM were located near blood vessel endothelial cells. No significant differences were detected with respect to the numbers of decidual uNK between early NP and PM. However, the number of decidual uNK cells was significantly reduced in CM and IM compared with early NP. The populations of decidual uNK cells were not significantly different between CM and IM. No uNK cells were detected in the villi of PM, CM or IM. The decrease of decidual uNK cells in late NP, CP and IM, compared with early NP, suggested that uNK cells served an important role in controlling trophoblast invasion and proliferation.

Abstract
A wild-born, captive-reared, 14 yr old, primiparous female California sea lion Zalophus californianus presented for anorexia of 14 d duration and abdominal distention. Routine complete blood cell count revealed leukocytosis with a neutrophilia, and serum chemistry revealed hypoalbumenemia and hyponatremia. Treatment with broad spectrum antibiotics and non-steroidal anti-inflammatories were started, but the animal continued to decline. Abdominal radiographs revealed a mature mineralized fetal skull and spine in the caudal abdomen and abdominal ultrasound revealed ascites but could not confirm the fetus. The patient was taken to surgery where a full term fetus was found outside of the uterus but within the fetal membranes, representing a secondary ectopic pregnancy. The patient passed away during surgery and was taken to necropsy. Gross necropsy revealed a diffuse peritonitis with yellow deposits over the serosal surfaces of the abdominal organs. The uterus appeared intact grossly and the ovaries appeared abnormal. The mesenteric, renal, and sub-lumbar nodes were enlarged and edematous. Histopathology revealed choriocarcinoma in the right uterine horn with evidence of chronic uterine rupture and protrusion of the placental tissue into the abdomen. The choriocarcinoma had metastasized locally as well as to the liver, spleen and lung. Choriocarcinoma is a highly malignant trophoblastic neoplasm that is rare in domestic animals. This case represents, to the authors' knowledge, the first report of gestational choriocarcinoma causing secondary ectopic pregnancy in a California sea lion and presents questions regarding pregnancy monitoring and management in a population of captive, minimally trained California sea lions.

Abstract
Choriocarcinoma is a rare, highly malignant neoplasm, which may occur during or following any type of pregnancy. This tumor often demonstrates rapid hematogenous spread to multiple organs, and is associated with high human chorionic gonadotropin (HCG) levels and a good response to chemotherapy. In the present study, the case of a 29-year-old female with distant metastatic choriocarcinoma [International Federation of Gynecology and Obstetrics (FIGO) stage IV; World Health Organization score, 15], who was misdiagnosed with pulmonary tuberculosis at a local hospital is presented. The major failure in the diagnosis of this case was that the patient's serum β-HCG levels were ignored initially. However, the patient received combined treatment with systematic multi-agent chemotherapy, whole-brain radiation therapy and gross total resection of the brain lesion at West China Second Hospital, and achieved complete remission. In conclusion, the accurate and prompt diagnosis of choriocarcinoma is crucial for a good outcome. Furthermore, in young female patients exhibiting symptoms such as pulmonary bleeding or neurological disturbances following a hydatidiform mole or a normal pregnancy, even in the absence of abnormal uterine bleeding, serum β-HCG levels must be analyzed and a diagnosis of choriocarcinoma must be considered.

Abstract
Complete hydatidiform moles (CHM) are abnormal pregnancies with no fetal development resulting from having two paternal genomes with no maternal contribution. It is important to distinguish CHM from partial hydatidiform moles, and non-molar abortuses, due to the increased risk of gestational trophoblastic neoplasia. We evaluated a series of products of conception (POC) (n=643) investigated by genome-wide microarray comparative genomic hybridisation (CGH) with the aim of refining our strategy for the identification of complete moles. Among 32 suspected molar pregnancies investigated by STR genotyping to supplement microarray CGH testing, we found 31.3% (10/32) CHM; all identified among 3.6% (10/272) early first trimester POC. We suggest that when using microarray CGH that genotyping using targeted STR analysis should be performed for all POC referrals to aid in the identification of CHM.

Abstract
Objectives: the purpose of this study is to use light microscopy and scanning electron microscopy to determine the effect of edema on the structure of the molar vesicle. Methods: samples were taken from the complete hydatidiform mole and processed using conventional light and scanning electron microscopy techniques and an observation protocol that identified four variables: factors underlying the development of edema; the condition of the trophoblast basement membrane, development of the villi, accumulation and degeneration of sulphated mucosubstances at stromal level. Results: light microscopy showed a permeable trophoblastic basement membrane, a swollen syncytium, edematous regions disorganizating the stromal region and causing ischemic necrosis of cells. Using scanning electron microscopy, the basement membrane was found to be distended and thickened, with large irregular holes for the entry and movement of liquid, leaving a wide range of fluids during the influx process and depriving stromal cells of nutrition. Conclusions: a new three-dimensional view of the changes brought about by the entry of fluids into the stroma of molar hydropic vesicles was provided by scanning electron microscopy and confirmed by light microscopy, thereby explaining the changes occurring at the level of the stroma as an effect of the edema.

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.

Abstract
Choriocarcinoma is the most malignant tumor of gestational trophoblastic disease arising from any gestation. It has a tendency toward relapse as well as metastasis. Here, a case of relapsed high-risk choriocarcinoma (FIGO stage IV, WHO score 12) in a 37-year-old female presenting with vaginal bleedings is described. Relapse developed at the site of the surgical scar from hysterectomy that had been performed 2 years earlier. Although the patient was treated with aggressive chemotherapy, she was in a bad general condition and died from infection and liver insufficiency.
