Choriocarcinoma is a human chorionic gonadotrophin (HCG)-secreting tumor that comprises vascular channels. It has a tendency for widespread metastasis, common sites for which include the lung, vagina, brain, liver, bone, intestine, and kidney. We describe a 30-year-old female who presented with hepatitis-like features and bilateral diminution of vision, and subsequently developed hemothorax and hemoperitoneum-all rare and seemingly unrelated manifestations which were finally attributable to metastases from gestational choriocarcinoma...

BACKGROUND: Pregnancy of unknown location presents a diagnostic challenge, in rare occasions leading to the diagnosis of malignancy. We describe a case of β-hCG-secreting nongestational primary gastric choriocarcinoma presenting as a pregnancy of unknown location. CASE: A 37-year-old woman, gravida 4 para 3013, presented with several days of vaginal bleeding and rising β-hCG level without ultrasound localization of pregnancy. The diagnosis of pregnancy of unknown location was made and methotrexate administered at a β-hCG level of 7,779 milli-international units/mL...

OBJECTIVE: Recently reported expression of programmed cell death 1 ligand 1 (PD-L1) in gestational trophoblastic diseases (GTDs) suggests that the immune tolerance of pregnancy might be hijacked during neoplastic process. We assessed PD-L1 protein expression in premalignant and malignant GTD lesions and analyzed associations with disease severity and chemotherapy outcomes. METHODS: We included 83 GTD whole-tissue sections from 76 patients in different treatment settings...

Bleomycin is a cytostatic drug commonly employed in the treatment of Hodgkin's disease, seminomas, and choriocarcinoma. Bleomycin may induce a chronic pulmonary inflammation that may progress to fibrosis. So far, only corticosteroids have been used in the treatment of bleomycin-induced lung disease with variable results. Pirfenidone is an antifibrotic drug that has been approved for the treatment of idiopathic pulmonary fibrosis. We report two cases of bleomycin-induced lung disease treated successfully with pirfenidone and oral corticosteroids...

The pro-inflammatory cytokine interferon-γ (IFN-γ) is critical for activating innate and adaptive immunity against tumors and intracellular pathogens. IFN-γ is secreted at the fetal-maternal interface in pregnant women and mice. The outer layer of the placenta in contact with maternal blood is composed of semi-allogeneic trophoblast cells, which constitute the fetal component of the fetal-maternal interface. The simultaneous presence of pro-inflammatory IFN-γ and trophoblast cells at the fetal-maternal interface appears to represent an immunological paradox, for trophoblastic responses to IFN-γ could potentially lead to activation of maternal immunity and subsequent attack of the placenta...

Choriocarcinoma presents usually as persistent trophoblastic disease, with prognosis worsening with duration from antecedent pregnancy. We present a unique case of a woman with choriocarcinoma who presented in the third trimester of pregnancy with eclampsia. She was managed with magnesium sulphate and underwent a caesarean section. However, she developed seizures in the post-partum period that were further investigated and attributed to intracranial metastatic lesions of Gestational Trophoblastic Neoplasia (GTN)...

Gestational choriocarcinoma metastasizing to the bones, especially to the spine, is extremely rare. In addition, there are few reports of choriocarcinoma during a viable pregnancy. We report a case of gestational choriocarcinoma that metastasized to the lumbar spine during a viable pregnancy in a 41-year-old woman with a history of a missed abortion. A heterogeneous cervical mass was detected at gestational week 16. Subsequently, a metastatic lesion appeared during the pregnancy, and fetal demise in utero occurred...

Choriocarcinoma is one of the gestational trophoblastic neoplasia (GTN) that originate in the chorionic villi and the extravillous trophoblast. Long non-coding RNA (lncRNA) is a type of non-protein-coding RNAs that have recently been implicated in human tumoriogenesis. The present study investigated the role of an lncRNA LINC00261 in the cell proliferation, metastasis and apoptosis in choriocarcinoma cell lines. The transcription level of lncRNA LINC00261 was significantly lower in choriocarcinoma tissues and in choriocrcinoma cell lines...

Chemotherapy is typically used to treat choriocarcinoma. However, a small proportion of this malignancy develops resistance to common chemotherapeutic drugs such as methotrexate (MTX) and floxuridine (FUDR). This study aimed to investigate the role and its potential mechanisms of chloride intracellular channel protein 1 (CLIC1) in the development of chemoresistance in choriocarcinoma JeG3 cells. Two chemoresistant sublines were induced from their parental cell line JeG3 through intermittent exposure to MTX (named JeG3/MTX) or FUDR (named JeG3/FUDR)...

OBJECTIVES: To determine if magnesium sulphate (MgSO4) prevents lipopolysaccharide (LPS)-induced cell death in an in vitro model of the human placenta. STUDY DESIGN: BeWo choriocarcinoma cells were treated with increasing concentrations of LPS (10-1000ng/ml) and MgSO4 ranging from 1 mM to 100 mM for 24 or 48h. For co-treatments, cells were pre-treated with 1mM MgSO4 for 1h and 200ng/ml LPS was then added for the remaining 48h. To assess viability an MTT assay was carried out along with nuclear staining to assess pyknotic nuclei...

Haemoperitoneum in women of reproductive age usually suggests either ruptured ectopic pregnancy or ruptured ovarian cysts. Metastatic choriocarcinoma is considered the least common cause of haemoperitoneum in women of childbearing age. We report a rare case of pancreatic and hepatic metastasis of choriocarcinoma in a young, 30-year-old female who had delivered 10 months prior at term gestation with no previous history of gestational trophoblastic disease or molar pregnancy. She had a short history of fever and pain in the right hypochondrium, with findings of hypovolaemic shock due to intraperitoneal haemorrhage...

Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had choriocarcinoma with metastases to the lungs, liver and kidneys. The 5th and 6th regimens with cisplatin for choriocarcinoma failed and the patient developed brain metastases...

Gestational trophoblastic disease (GTD) is a group of conditions that originate from the abnormal proliferation of trophoblastic cells. GTDs encompass hydatidiform moles (HMs) and gestational trophoblastic neoplasia (GTN). GTNs are a group of malignant diseases that require chemotherapy, or more aggressive treatment. There is a requirement for more tumor markers to predict the development of GTN from HMs. The current study evaluated the expression of maspin and tumor protein p53 (p53) in GTD, and their role in predicting the development of GTN...
