This study was to identify the biomarkers for the malignancy and poor prognosis in patients with ovarian cancer. The protein expression of p38MAPK family isoform p38α (p38α) and activating transcription factor 2 (ATF2) was measured in 120 ovarian serous adenocarcinomas and 34 normal fallopian tubes using immunohistochemistry. Stable OV-90 cells expressing p38α and ATF2 inhibitor were established using shRNA lentivirus. Cell proliferation, invasion, and migration were analyzed in vitro. Tumor growth and chemosensitivity were investigated in xenograft tumor models...

BACKGROUND: Rucaparib, a poly(ADP-ribose) polymerase inhibitor, has anticancer activity in recurrent ovarian carcinoma harbouring a BRCA mutation or high percentage of genome-wide loss of heterozygosity. In this trial we assessed rucaparib versus placebo after response to second-line or later platinum-based chemotherapy in patients with high-grade, recurrent, platinum-sensitive ovarian carcinoma. METHODS: In this randomised, double-blind, placebo-controlled, phase 3 trial, we recruited patients from 87 hospitals and cancer centres across 11 countries...

There is a general agreement that a large subpopulation of serous ovarian cancers arise from the fallopian tube mucosal epithelium. However, there is still some debate as to whether the cancers originate from a secretory or ciliate cell lineage. One well established method for determining the origin of a cell line is to document the expression of genes and proteins that are cell type specific. Lineage or tissue specific patterns of gene expression are evidence of direct decent from a given cell type within a tissue...

In the absence of significant benefit from either novel therapeutics or screening, the focus of decreasing ovarian cancer incidence and mortality has shifted toward primary prevention. Histopathologic data have demonstrated that up to 70% of ovarian cancers may actually arise from the fallopian tube. This has led to the increased adoption of opportunistic salpingectomy as a tool for ovarian cancer prevention. In turn, the potential surgical risks and ovarian cancer prevention of this emerging practice have generated multiple studies...

OBJECTIVE: To identify risk factors for surgical site infection and to define rates associated with cytoreductive surgery before and after implementation of an infection prevention bundle. METHODS: We conducted a prospective quality improvement study. Patients who underwent ovarian, fallopian tube, or peritoneal cancer cytoreductive surgery at an academic tertiary care center from April 2014 to April 2016 were prospectively enrolled. Patient demographics, surgical variables, and surgical site infection rates were compared with a historical cohort after introduction of a 5-point infection prevention bundle, including: 1) preoperative and intraoperative skin preparation with 4% chlorhexidine and intraoperative vaginal preparation with 4% chlorhexidine; 2) preoperative use of oral antibiotics and mechanical bowel preparation; 3) appropriate timing of intraoperative antibiotics; 4) adoption of enhanced sterile surgical techniques for colon procedures and incisional closure; and 5) perioperative incision management...

Adnexal torsion is the fifth most common gynecologic surgical emergency, requiring clinician and radiologist awareness. It involves the rotation of the ovarian tissue on its vascular pedicle leading to stromal edema, hemorrhagic infarction, and necrosis of the adnexal structures with the subsequent sequelae. Expedient diagnosis poses a difficult challenge because the clinical presentation is variable and often misleading. Adnexal torsion can mimic malignancy as it can take a subacute, intermittent, or chronic course, and thereby can be complicated to diagnose...

The fallopian tube epithelium (FTE) has been recognized as a site of origin of high-grade serous ovarian cancer (HGSC). However, the absence of relevant in vitro human models that can recapitulate tissue-specific architecture has hindered our understanding of FTE transformation and initiation of HGSC. Here, induced pluripotent stem cells (iPSCs) were used to establish a novel 3-dimensional (3D) human FTE organoid in vitro model containing the relevant cell types of the human fallopian tube as well as a luminal architecture that closely reflects the organization of fallopian tissues in vivo...

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...

Mutations in BRCA genes increase the risk of ovarian cancer, yet no method for early diagnosis is available. Some serous ovarian tumors are hypothesized to stem from cells of the fallopian tube fimbria. Using a novel method of computerized morphometry of the fimbrial epithelium, this study aimed to detect morphologic differences in noncancerous fimbriae between BRCA mutation carriers and noncarriers, and between healthy and serous ovarian cancer patients. Twenty-four fimbriae from healthy women (13 BRCA+, 11 BRCA-) and 21 fimbriae from women with serous ovarian cancer (10 BRCA+, 11 BRCA-), all reported as "normal" by hematoxylin and eosin examination, were subjected to computerized histomorphometric analysis...

The morbidity and mortality due to tuberculosis (TB) is high worldwide, and the burden of disease among women is significant, especially in developing countries. Mycobacterium tuberculosis bacilli reach the genital tract primarily by haematogenous spread and dissemination from foci outside the genitalia with lungs as the common primary focus. Genital TB in females is a chronic disease with low-grade symptoms. The fallopian tubes are affected in almost all cases of genital TB, and along with endometrial involvement, it causes infertility in patients...

OBJECTIVES: To assess a simple algorithm of CA125, HE4 and Symptom Index to predict ovarian cancer in women with a pelvic mass. METHODS: This was a prospective study of women referred to a gynecologic oncology clinic for surgical evaluation of a pelvic mass. Preoperatively, women completed a SI and had serum markers drawn. Results were correlated with pathology. A triple screen was considered positive if at least 2 of the 3 markers were abnormal (positive SI, CA125≥35U/mL, HE4≥140pmol/L)...

A previously healthy 10-year-old girl presented to the emergency department with a 1-day history of abdominal pain. She was afebrile with an elevated white blood cell count and a negative pelvic ultrasound. The pain resolved while in hospital, and the patient was discharged home. The patient returned 10 days later, and the pain now migrated from the left flank to the subumbilical region. The patient now had an elevated white blood cell count and C-reactive protein. On pelvic ultrasound, the patient had a large midline mass and a normal right ovary...

BACKGROUND: The Cancer Genome Atlas Research Network reported that high-grade serous carcinoma (HGSC) can be classified based on gene expression profiles into four subtypes, termed "immunoreactive," "differentiated," "proliferative," and "mesenchymal." We previously established a novel histopathological classification of HGSC, corresponding to the gene expression subtypes: immune reactive (IR), papillo-glandular (PG), solid and proliferative (SP), and mesenchymal transition (MT). The purpose of this study is to identify distinct clinical findings among the four pathological subtypes of HGSC, as well as to predict pathological subtype based on preoperative images...

Communities of microbiota have been associated with numerous health outcomes, and while much emphasis has been placed on the gastrointestinal niche, there is growing interest in the microbiome specific for female reproductive health and the health of their offspring. The vaginal microbiome plays an essential role not only in health and dysbiosis, but also potentially in successful fertilization and healthy pregnancies. In addition, microbial communities have been isolated from formerly forbidden sterile niches such as the placenta, breast, uterus, and Fallopian tubes, strongly suggesting an additional microbial role in women's health...

Chlamydia trachomatis is an obligate intracellular bacterium whose only natural host is man. Although asymptomatic in most women, genital tract chlamydial infections are a leading cause of pelvic inflammatory disease, tubal factor infertility and ectopic pregnancy. C. trachomatis has evolved successful mechanisms to avoid destruction by autophagy and the host immune system and persist within host epithelial cells. The intracellular form of this organism, the reticulate body, can enter into a persistent non-replicative but viable state under unfavorable conditions...
