Pathogenic germline BRCA1, BRCA2 (BRCA1/2), and several other gene variants predispose women to primary ovarian, fallopian tube, and peritoneal carcinoma (OC), although variant frequency and relevance information is scarce in Japanese women with OC. Using targeted panel sequencing, we screened 230 unselected Japanese women with OC from our hospital-based cohort for pathogenic germline variants in 75 or 79 OC-associated genes. Pathogenic variants of 11 genes were identified in 41 (17.8%) women: 19 (8.3%; BRCA1), 8 (3...

OBJECTIVES: Hysterosalpingo-foam sonography (HyFoSy) has been suggested to be a possible less invasive alternative to hysterosalpingography (HSG), which is the reference standard for confirmation of tubal occlusion after Essure (Bayer AG, Leverkusen, Germany) hysteroscopic sterilization. The purpose of our study was to evaluate the accuracy of HyFoSy compared to HSG for confirmation of tubal occlusion after Essure hysteroscopic sterilization. METHODS: A prospective study included 90 patients who underwent Essure hysteroscopic sterilization...

Bivalent chromatin domains containing both active H3K4me3 and repressive H3K27me3 histone marks define gene sets poised for expression or silencing in differentiating embryonic stem (ES) cells. In cancer cells aberrantly poised genes may facilitate changes in transcriptional states after exposure to anti-cancer drugs. In this study, we used ChIP-seq to characterize genome-wide positioning of H3K4me3 and H3K27me3-associated chromatin in primary high-grade serous ovarian carcinomas and in normal ovarian surface and fallopian tube tissue...

The initial molecular events that lead to malignant transformation of the fimbria of the fallopian tube (FT) through high-grade serous ovarian carcinoma (HGSC) remain poorly understood. In this study, we report that increased expression of signal transducer and activator of transcription 3 (pSTAT3 Tyr705) and suppression or loss of protein inhibitor of activated STAT3 (PIAS3) in FT likely drive HGSC. We evaluated human tissues-benign normal FT, tubal peritoneal junction (TPJ), p53 signature fallopian tube tissue, tubal intraepithelial lesion in transition (TILT), serous tubal intraepithelial carcinoma (STIC) without ovarian cancer, and HGSC for expression of STAT3/PIAS3 (compared with their known TP53 signature) and their target proliferation genes...

Poly-ADP-ribosylation (PARylation) is a protein posttranslational modification (PTM) that is critically involved in many biological processes that are linked to cell stress responses. It is catalyzed by a class of enzymes known as poly-ADP-ribose polymerases (PARPs). In particular, PARP1 is a nuclear protein that is activated upon sensing nicked DNA. Once activated, PARP1 is responsible for the synthesis of a large number of PARylated proteins and initiation of the DNA damage response (DDR) mechanisms. This observation provided the rationale for developing PARP1 inhibitors for the treatment of human malignancies...

We herein reported a rare case of an occult fallopian tube carcinoma first detected from the diaphragm metastasis. An 83-year-old woman who had a 30-mm tumor on the right diaphragm underwent radical resection. Pathologically, the tumor was diagnosed as a high-grade serous adenocarcinoma, suggesting metastasis from the pelvic visceral carcinoma. Although the primary site could not be detected by imaging examinations, laparoscopy revealed multiple peritoneal disseminations; therefore, total hysterectomy was performed...

OBJECTIVE: We conducted a multicenter clinicopathological study to characterize patients with high-grade serous carcinoma presenting as primary peritoneal carcinoma (clinical PPC). METHODS: At 9 sites in Japan, patients with clinical PPC diagnosed according to Gynecologic Oncology Group criteria were enrolled retrospectively. The Gynecologic Oncology Group criteria allow for minor ovarian involvement by high-grade serous carcinoma. There was no systematic detailed histopathological review of the fallopian tubes to determine whether they were involved by serous carcinoma...

Women known to have significantly elevated ovarian cancer risk due to genetic mutations or family history can reduce this risk by surgically removing both ovaries and fallopian tubes (RRBSO, risk-reducing bilateral salpingo-oophorectomy). We used interpretive phenomenological analysis (IPA) to explore the psychosocial experiences of women who chose RRBSO for cancer prevention. We extended the traditional use of IPA to compare the experiences of women who chose RRBSO for cancer prevention to those of women who underwent similar gynecologic surgery for benign indications...

Stressful early life experiences cause immune dysregulation across the lifespan. Despite the fact that studies have identified childhood sexual abuse (CSA) survivors as a particularly vulnerable group, only a few attempts have been made to study their lived-experience of the physical health consequences of CSA. The aim of this study was to explore a female CSA survivor's lived-experience of the physical health consequences of CSA and how she experienced the reactions of healthcare providers. Seven interviews were conducted with this 40-year-old woman, Anne, using a phenomenological research approach...

In this study it was evaluated if increased rounds of gonadotropin stimulation could affect in mice: i) expression levels of proteins regulating cell cycle and DNA repair in fallopian tubes and ii) meiotic spindle morphology of ovulated oocytes. To this end, adult female mice were subjected or not (Control) to 6 or 8 rounds of gonadotropin stimulation. Ovulated oocytes were incubated with anti A/B Tubulin to evaluate spindle morphology. Fallopian tubes were analyzed to detect Cyclin D1, phospho-p53/p53, phospho-AKT/AKT, phospho-GSK3B/GSK3B, SOX2, OCT3/4, phospho-B-catenin/B-catenin, phospho-CHK1, and phospho-H2A...

BACKGROUND: High-grade serous carcinoma (HGSC) is the most common tubo-ovarian cancer. The fallopian tube harbours the precursor lesion: serous tubal intraepithelial carcinoma (STIC). Bilateral salpingo-oophorectomy is an effective risk-reducing surgical (RRS) strategy for breast cancer susceptibility gene mutation carriers (BRCAm). The value of RRS in those without defined genetic risk is unknown but these women represent a substantial cohort in prophylactic surgical practice. METHODS: This is a retrospective review of RRS at an Irish university teaching hospital...

A 59-year-old woman developed a rash and severe arthralgia, which primarily affected her fingers. She displayed digital arthritis and nodules on the hands, chest, face, and oral cavity. Blood samples were normal. Skin biopsies revealed histiocytic proliferation. The surface marker profile and clinical findings were consistent with multicentric reticulohistiocytosis, which may occur as a paraneoplastic phenomenon. On workup, she was diagnosed with an otherwise asymptomatic stage IVC fallopian tube cancer. She experienced little effect of prednisolone, but her condition improved on antineoplastic treatment...

Current evidences indicate that the fallopian tube plays a major role in the pathogenesis of epithelial ovarian cancer (EOC). Salpingectomy represents a novel and potentially effective risk-reducing option. In this study, there were 1822 patients diagnosed and treated for EOC or primary peritoneal cancer (PPC) at Department of Gynecologic Oncology, Tianjin Medical University Cancer Institute and Hospital from January 1, 2007 to April 30, 2017. Among them, 198 patients with a history of gynecological surgery because of benign diseases were enrolled to analyze further...

Background: Recognition that serous tubal intraepithelial carcinoma (STIC) may represent the first manifestation of many high-grade cancers that were once considered ovarian primary tumors has led to changes in diagnostic practices that could dramatically increase the reporting of tubal carcinomas in US population-based cancer registries. Further, increased detection of early-stage tubal carcinomas through increased recognition coupled with meticulous pathology processing protocols raises important unanswered questions about the clinical behavior of such lesions, which can only be answered using large data sets...

PurposeThe clinical utility of screening unselected individuals for pathogenic BRCA1/2 variants has not been established. Data on cancer risk management behaviors and diagnoses of BRCA1/2-associated cancers can help inform assessments of clinical utility.MethodsWhole-exome sequences of participants in the MyCode Community Health Initiative were reviewed for pathogenic/likely pathogenic BRCA1/2 variants. Clinically confirmed variants were disclosed to patient-participants and their clinicians. We queried patient-participants' electronic health records for BRCA1/2-associated cancer diagnoses and risk management that occurred within 12 months after results disclosure, and calculated the percentage of patient-participants of eligible age who had begun risk management...
