Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor, which are considered malignant tumors. Based on defined histopathological criteria, molar pregnancy is divided into partial and complete hydatidiform mole. Especially in the case of early complete mole, the diagnosis can be quite challenging and often necessitates additional molecular or immunohistochemical methods...

PURPOSE: Choriocarcinoma (CC) is the most malignant gestational trophoblastic disease that often develops from complete hydatidiform moles (CHM). Neither the mechanism of CC development nor its progression is yet characterized. We have recently identified EG-VEGF as a novel key placental growth factor that controls trophoblast proliferation and invasion. EG-VEGF acts via two receptors PROKR1 and PROKR2. Here, we demonstrate that EG-VEGF receptors can be targeted for CC therapy. EXPERIMENTAL DESIGN: Three approaches were used, i) a clinical investigation comparing circulating EG-VEGF in Control (n=20) and in distinctive CHM (n=38) and CC (n=9) cohorts, ii) an in vitro study investigating EG-VEGF effects on the CC cell line JEG3, and iii) an in vivo study including the development of a novel CC mouse model, through a direct injection of JEG3-luciferase into the placenta of gravid SCID-mice...

RATIONALE: Choriocarcinoma accompanied with pulmonary embolism (PE) is rare and difficult to diagnose and treat. There are about 25 cases reported in literature, which presented variable clinical characteristics and prognosis. PATIENT CONCERNS: We reported a case of choriocarcinoma presenting PE as the first manifestation in a 26-year-old Chinese female. DIAGNOSES: Four months before her admission to our hospital, she presented to a local hospital with respiratory manifestations, and was first diagnosed as bronchitis and treated with antibiotics without improvement, and subsequently suspected of having pulmonary tuberculosis and receive anti-tuberculosis therapy, with no response...

Choriocarcinoma is a highly malignant neoplasm arising from the trophoblast of a human pregnancy, which may have distant spread to multiple organs, particularly to the lung. We report a case of a pulmonary arteriovenous fistula that developed after chemotherapy within a choriocarcinoma metastasis. A 24-year-old female with a history of uterine choriocarcinoma presented with multiple hypervascular pulmonary nodules on the initial chest computed tomography (CT) scan, consistent with lung metastases. Four months after chemotherapy, follow-up chest CT revealed a decrease in the size and vascularity of the lung metastases, except for 1 nodule that persisted with marked contrast enhancement and developed a communication with a pulmonary artery and vein...

Choriocarcinoma is an uncommon malignant neoplasm, which can be either gestational or nongestational in origin. Distinction of these subtypes has prognostic and therapeutic implications. Twenty-two tumors were genotyped using polymerase chain reaction amplification of 15 short tandem repeat loci and the amelogenin locus (XY determination). DNA patterns from tumor and maternal tissue, as well as villous tissue from any available prior or concurrent gestation, were compared, to determine gestational versus nongestational nature (containing vs...

p40, one of the two isomers of p63, is nowadays widely used for diagnosis of squamous cell carcinoma, especially in subtyping non-small cell carcinoma on lung biopsies. We describe a case in which lung tumour was misdiagnosed as squamous cell carcinoma due to p40 immunopositivity. A 36-year-old lady presented with cough and left sided chest pain of 2 months duration. Chest imaging revealed a lesion in left lower lobe of the lung and biopsy was suggestive of squamous cell carcinoma. However, past history revealed amputation of great toe for non-healing discharging ulcer which on histopathology was diagnosed as choriocarcinoma...

The folate receptor (FR) is expressed in a variety of gynecological cancer types. It has been widely used for tumor targeting with folic acid conjugates of diagnostic and therapeutic probes. The cervical KB tumor cells have evolved as the standard model for preclinical investigations of folate-based (radio) conjugates. In this study, a panel of FR-expressing human cancer cell lines-including cervical (HeLa, KB, KB-V1), ovarian (IGROV-1, SKOV-3, SKOV-3.ip), choriocarcinoma (JAR, BeWo) and endometrial (EFE-184) tumor cells-was investigated in vitro and for their ability to grow as xenografts in mice...

Herein we report a very rare entity of multiple hemorrhagic metastases to the brain from a primary lung choriocarcinoma in a young woman. The patient presented with recent onset of progressive headache, decreased level of consciousness and multiple episodes of vomiting. CT of the head revealed multiple hemorrhagic lesions within the brain. The patient's serum B-human chorionic gonadotrophin was increased.  A chest X-ray revealed a right lung mass. The patient urgently underwent operative excision of the lesion in the posterior fossa, so as to prevent impending tonsillar herniation...

Gestational choriocarcinomas are highly malignant tumors with elevated serum human chorionic gonadotropin (hCG) levels. We report an extremely rare case of a 27-year-old woman who presented 4 months after normal delivery, with pulmonary, renal and intracardiac metastases of a choriocarcinoma. No primary uterine tumor was found. She was surgically treated for the renal and cardiac metastases as well as with cisplatin-etoposide chemotherapy. No recurrence has been observed 16 years after initial diagnosis, and the patient was able to have a second child...

Interleukin-33 (IL-33) promotes migration of cancer cells through downregulating the expression of E-cadherin. Previous studies have demonstrated that IL‑33 stimulates the proliferation of trophoblasts. However, the effect of IL‑33 on the adhesion and invasion of trophoblasts has not been investigated in detail. In the present study, the expression of IL‑33 and its receptor, IL‑1 receptor‑like 1 (ST2), was examined in villi from women during early pregnancy using immunohistochemistry. ST2 expression on human trophoblast and choriocarcinoma cell lines JAR, BeWo, JEG3 and HTR8 was confirmed by flow cytometry (FCM) assay...

Gestational trophoblastic neoplasias (GTNs) are a group of pregnancy-related neoplasms, which include chorioadenoma destruens (invasive mole), placental site trophoblastic tumor, and choriocarcinoma. Although the role of F-FDG PET/CT is still undefined in GTN, in selected cases, it can have significant impact on patient management. Here, we present the case of a 29-year-old woman with hydatidiform mole suggestive of GTN 3 months after evacuation. F-FDG PET/CT demonstrated chorioadenoma destruens (invasive mole) and ruled out metastasis in this case...

Cigarette smoke (CS) causes about 480,000 deaths each year worldwide, and it is well-known to have harmful effects on the human body, leading to heart disease, stroke, lung cancer, and cardiovascular problems. In this study, the effects of formaldehyde (FA) and benzene (Bz), the main components of CS, on cell proliferation and epithelial mesenchymal transition (EMT) of JEG-3 human choriocarcinoma cells were examined to confirm the relationship between CS components and placenta carcinoma. Upon MTT assay, FA (10(-8) M to 10(-5) M) and Bz (10(-11) M to 10(-8) M) increased JEG-3 cell proliferation...

Estrogen biosynthesis during pregnancy is dependent on the collaboration between the fetus producing the androgen precursors, and the placenta expressing the enzyme aromatase (CYP19). Disruption of estrogen production by contaminants may result in serious pregnancy outcomes. We used our recently developed in vitro co-culture model of fetoplacental steroidogenesis to screen the effects of three neonicotinoid insecticides on the catalytic activity of aromatase and the production of steroid hormones. A co-culture of H295R human adrenocortical carcinoma cells with fetal characteristics and BeWo human choriocarcinoma cells which display characteristics of the villous cytotrophoblast was exposed for 24h to various concentrations of three neonicotinoids: thiacloprid, thiamethoxam and imidacloprid...
