Objective: To review retrospectively the causes of death in unselected patients with gestational trophoblastic neoplasia (GTN).
Study Design: Between 1975 and 2010, 905 patients with GTN were treated at the Sheffield Centre. Twenty-four of them died. The medical records of these patients were reviewed.
Results: Of the 24 patients, 11 died during initial treatment. A further 8 died from disease relapse and progression of the disease. The cause of death was unrelated in the other 5, who were excluded from analysis. For the remaining 19 patients, death was due to metastatic tumor in 13 and was treatment related in 6. Adverse prognostic features for death from GTN included histology (7 were placental site trophoblastic tumor [PSTT]), risk score (15 were high risk) and chemotherapy resistance. All 5 of the patients who died of acute treatment-related complications (invariably sepsis and/or multiorgan failure) still had active GTN at the time of death; all were treated prior to 1987. One multitreated patient died of acute myeloid leukemia 3 years posttreatment.
Conclusion: Metastatic multidrug-resistant PSTT was and still is the single most important cause of death. Death from choriocarcinoma was with nonpulmonary metastases not responding to initial treatment. Early treatment-related death (from sepsis) is nowadays avoidable.

Preeclampsia is characterized by insufficient invasion of extravillous trophoblasts and is a consequence of failed adaption of extravillous trophoblasts to changes in the intrauterine environment developing embryo. Specific miRNAs are implicated in the development of preeclampsia (PE). miR-455-5p is present at low levels in PE but its role is not known.

Elevated glucose levels at the fetal-maternal interface are associated with placental trophoblast dysfunction and increased incidence of pregnancy complications. Trophoblast cells predominantly utilize glucose as an energy source, metabolizing it through glycolysis in the cytoplasm and oxidative respiration in the mitochondria to produce ATP. The TGFβ1/SMAD2 signaling pathway and the transcription factors PPARγ, HIF1α, and AMPK are key regulators of cell metabolism and are known to play critical roles in extravillous trophoblast cell differentiation and function.

Intrauterine growth restriction (IUGR) is the second most common obstetric complication after preterm labor. Appropriate trophoblast differentiation and placental structure, growth and function are key for the maintenance of pregnancy and normal fetal growth, development and survival. Extravillous trophoblast cell proliferation, migration and invasion are regulated by molecules produced by the fetomaternal interface, including autocrine factors produced by the trophoblast, such as insulin‑like growth factor (IGF)‑1.

Gestational trophoblastic neoplasia (GTN) comprises a category of malignant or potentially malignant tumors that arise from gestational trophoblasts. Almost all cases of GTN experience a recurrence within the first year following treatment, although recurrences become rare after five years. Recurrent GTN tends to have a poor prognosis, primarily due to challenges in management, a high rate of relapse, and a low five-year survival rate.

The placental DNA methylation landscape is unique, with widespread partially methylated domains (PMDs). The placental "methylome" is conserved across mammals, a shared feature of many cancers, and extensively studied for links with pregnancy complications. Human trophoblast stem cells (hTSCs) offer exciting potential for functional studies to better understand this epigenetic feature; however, whether the hTSC epigenome recapitulates primary trophoblast remains unclear.
