A retrospective study was conducted to determine if a chemotherapy regimen incorporating cis-platinum, etoposide, and actinomycin D (PEA) was associated with an outcome different from that of the standard triple regimen of methotrexate, actinomycin D, and chlorambucil (MAC) in patients with gestational trophoblastic tumor and liver metastases. Subjects were treated at the King Faisal Specialist Hospital Gestational Trophoblastic Center (KFSH-GTC) between January 1980 and December 1990. Of 19 patients with gestational trophoblastic tumor and liver metastases, 6 received MAC chemotherapy, and 8 received PEA. Five patients were terminally ill and received palliative treatment only. Treatment outcome was measured by beta-subunit human chorionic gonadotropin assay (beta-HCG) and by imaging studies which included ultrasound, computerized axial tomography, and/or magnetic resonance imaging. Durable remission was obtained in 5 of 8 (62.5%) PEA-treated patients and none of 6 MAC-treated patients. There was no difference in risk status or World Health Organization (WHO) prognostic score between the two groups. We conclude that PEA is a relatively effective chemotherapy regimen in the treatment of gestational trophoblastic tumor with liver metastases, and it may be worthy of consideration for prospective clinical trials.

Background: The "Healthy China" initiative, along with advancements in technology for cancer diagnosis and treatment, has significantly enhanced outcomes for patients with gynecologic tumors. The trends of late marriage and delayed childbirth have led to an increasing number of women diagnosed with gynecologic cancers who are seeking fertility preservation in China. This issue is critical yet often overlooked in clinical practice.

BACKGROUND Gestational trophoblastic diseases (GTDs) are a group of benign and malignant tumors that arise from placental tissue. Ectopic pregnancies most commonly occur within the fallopian tubes. The estimated incidence of ectopic gestational trophoblastic diseases (GTDs) is approximated at 1.

Background: Sirtuins and FoxO1 are reported to be important in the pathophysiology of preeclampsia. This study aimed to investigate whether serum FoxO1 and SIRT2 concentrations differ between preeclampsia and normal pregnancy and also to compare these markers in early- and late-onset preeclampsia.
Methods: This cross-sectional study was conducted on 27 women with early-onset preeclampsia, 27 women with late-onset preeclampsia, and 26 healthy normotensive pregnant controls.

In mammals, blastocyst-stage trophectoderm (TE) contacts the maternal body at the time of implantation and forms the placenta after implantation, which supports the development of the fetus. Studying gene function in TE and placenta is important to understand normal implantation and pregnancy processes and their dysfunction. However, genetically modified mice are commonly generated by manipulating pronuclear-stage zygotes, which modify both the genome of the fetus and the placenta.

The mechanistic target of rapamycin (mTOR) system is vital to placental development, formation, and function. Alterations in this system in the placenta have been associated with altered fetal growth. However, changes in placental mTOR signaling across gestation are poorly understood.
