Ovarian high-grade serous carcinoma (HGSC) is the most lethal gynecological malignancy. Prevailing evidences suggest that drug resistance and recurrence of ovarian HGSC are caused by the presence of cancer stem cells. Therefore, targeting cancer stems is appealing, however, all attempts to date, have failed. To circumvent this limit, we analyzed differential transcriptomes at early differentiation of ovarian HGSC stem cells and identified the developmental transcription factor GATA3 as highly expressed in stem, compared to progenitor cells...

Ovarian cancer (OVC) is the most lethal of the gynecological malignancies, with diagnosis often occurring during advanced stages of the disease. Moreover, a majority of cases become refractory to chemotherapeutic approaches. Therefore, it is important to improve our understanding of the molecular dependencies underlying the disease to identify novel diagnostic and precision therapeutics for OVC. Cancer cells are known to sequester iron, which can potentiate cancer progression through mechanisms that have not yet been completely elucidated...

Uterine perivascular epithelioid cell tumors (PEComas) are rare neoplasms that may show overlapping morphology and immunohistochemistry with uterine smooth muscle tumors. In this study, we evaluated the morphologic, immunohistochemical, and molecular features of 32 PEComas, including 11 with aggressive behavior. Two distinct morphologies were observed: classic (n=30) and those with a lymphangioleiomyomatosis appearance (n=2). In the former, patients ranged from 32 to 77 (mean: 51) years and 13% had tuberous sclerosis...

BACKGROUND: An estimated 5-10% of breast and ovarian cancers are due to hereditary causes such as hereditary breast and ovarian cancer (HBOC) syndrome. Medicare, the third-party payer that covers 44 million patients in the United States, has implemented a set of clinical criteria to determine coverage for the testing of the BRCA1 and BRCA2 genes. These criteria, developed to identify carriers of BRCA1/2 variants, have not been evaluated in the panel testing era. This study investigated a series of Medicare patients undergoing genetic testing for HBOC to determine the efficacy of genetic testing criteria in identifying patients with hereditary risk...

BACKGROUND: Pelvic organ prolapse (POP) is an increasing medical problem with complex diagnostics and controversial surgical management. It causes a series of dysfunctions in the gynecological, urinary, and anorectal organs. Numerous procedures have been proposed to treat these conditions, but in recent years, ventral mesh rectocolposacropexy (VMRCS) has emerged as the procedure of choice for the surgical treatment of POP, especially by a laparoscopic approach. This surgical technique limits the risk of autonomic nerve damage, and the colpopexy allows the correction of concomitant prolapse of the middle compartment...

BACKGROUND: Three-dimensional (3D) vision technology has recently been validated for the improvement of surgical skills in a simulated setting. Clinical studies on specific operations have been published in the field of general, urologic, and gynecologic laparoscopic surgery. We hypothesized that 3D vision laparoscopic right colectomy has better intra and short-term postoperative outcomes than two-dimensional (2D) vision. AIM: The outcomes of this review and meta-analysis were to compare the 3D vision and the 2D vision laparoscopic right colectomy...

Purpose: In this study we sought to: 1) determine rates of burnout and other associated indices of psychosocial distress such as alcohol and substance abuse, 2) establish the baseline performance of gynecologic oncologists on several positive psychology metrics, 3) determine if increased hope, resilience, and flourishing are associated with decreased burnout. Methods: A survey of members of the Society of Gynecologic Oncology (SGO) was conducted in spring of 2017...

Background: Ovarian cancer is the deadliest gynecologic malignancy and the fifth leading cause of cancer death among women living in the USA. Treatment for ovarian cancer that follows the guidelines published by the National Comprehensive Cancer Network is associated with a 33% decrease in disease-specific mortality, yet fewer than 40% of women with ovarian cancer receive guideline-adherent treatment. Little is known about the process by which women with ovarian cancer, their unpaid caregivers, and physicians make decisions about ovarian cancer treatment...

Background: Delayed cord clamping (DCC) results in decreased iron deficiency in infancy. The American College of Obstetrics and Gynecology has called for research on the optimal time to clamp the cord during cesarean deliveries (CD). Our objective was to conduct a pilot trial examining the safety of delayed cord clamping (DCC) for maternal-infant dyads during elective cesarean delivery (CD). Methods: We enrolled 39 dyads [23 at 90 s, 16 at 120 s; (DCC Pilot)] between 10/2013 and 9/2014...

Gynecologic cancers are among the leading causes of death worldwide, ovarian cancer being the one with the highest mortality rate. Olaparib is a targeted therapy used in patients presenting mutations in BRCA1 and BRCA2 genes. The aim of this study was to describe BRCA1 and BRCA2 gene variants in Mexican patients with ovarian cancer. Sequencing of BRCA1 and BRCA2 genes from tumors of 50 Mexican patients with ovarian cancer was made in a retrospective, non-randomized, and exploratory study. We found genetic variants in 48 of 50 cases...

The oncogenic role of Wilms' tumor 1 (WT1) which is regarded as a promising target antigen for cancer immunotherapy has been demonstrated in many types of cancer, but the relationship between expression of WT1 and the prognosis value in gynecological cancer reminds unclear.We performed a meta-analysis with thirteen published studies including 2205 patients searched from PubMed, EMBASE, Web of Science, and Google Scholar, whose results are expressed by overall survival (OS) or disease-specific survival (DSS) or disease-free survival or relapse/recurrence-free survival (RFS) or progression-free survival (PFS) in patients with gynecological cancer...
