PURPOSE: To clarify the MRI findings for primary fallopian tube cancer (PFTC). MATERIALS AND METHODS: MRI findings for 11 patients who were pathologically diagnosed with PFTC at our institute were retrospectively reviewed. MRI findings (shape, appearance, signal intensity, ADC value, enhancement patterns, and location of the primary tumor, the morphologic appearance of the ipsilateral ovary, and intrauterine fluid collection) were evaluated and compared with pathological findings including histological subtype and PFTC location...

Persistent Müllerian Duct Syndrome (PMDS) is a form of disordered sex development in which rudimentary Müllerian structures are identified in phenotypically and genotypically normal males. It is caused by defects in the anti-Müllerian hormone (AMH) system. Since patients with PMDS present with undescended testes, testosterone production by Leydig cells later in life is often decreased. The role of androgens in prostate cancerogenesis is well known. Cryptorchid testes and diminished testosterone levels in post pubertal life in patients with PMDS play a protective role against prostate cancer, and hence, prostate cancer is a rare event in patients with PMDS...

Recent studies have provided evidence that the secretory cells of the fallopian tube (oviduct) are a probable origin for high-grade serous ovarian carcinoma. In addition to secretory cells, the fallopian tube epithelium consists of ciliated cells and CD44+ undifferentiated stem-like cells. Loss of PAX2 expression is recognized as an early event in epithelial transformation, but the specific role of PAX2 in this transition is unknown. The aim of this study was to define the role of PAX2 in oviductal epithelial (OVE) cells and its response to transforming growth factor β1 (TGFβ), characterizing specifically its potential involvement in regulating stem cell-like behaviors that may contribute to formation of cancer-initiating cells...

High-grade serous ovarian carcinoma (HGSOC) is the most frequent type of ovarian cancer and has a poor outcome. It has been proposed that fallopian tube cancers may be precursors of HGSOC but evolutionary evidence for this hypothesis has been limited. Here, we perform whole-exome sequence and copy number analyses of laser capture microdissected fallopian tube lesions (p53 signatures, serous tubal intraepithelial carcinomas (STICs), and fallopian tube carcinomas), ovarian cancers, and metastases from nine patients...

Optical coherence tomography (OCT) yields microscopic volumetric images representing tissue structures based on the contrast provided by elastic light scattering. Multipatient studies using OCT for detection of tissue abnormalities can lead to large datasets making quantitative and unbiased assessment of classification algorithms performance difficult without the availability of automated analytical schemes. We present a mathematical descriptor reducing the dimensionality of a classifier's input data, while preserving essential volumetric features from reconstructed three-dimensional optical volumes...

Long intergenic non-protein coding RNA, regulator of reprogramming (linc-ROR) is an intergenic long non-coding RNA (lncRNA) previously shown to contribute to tumorigenesis in several malignancies. However, little is known about whether linc-ROR has a role in ovarian cancer progression. In this study, we found that linc-ROR expression was increased in high-grade ovarian serous cancer tissues compared with normal ovarian tissues or normal fallopian tube tissues. Furthermore, the level of linc-ROR expression was associated with ovarian cancer International Federation of Gynecology and Obstetrics stage and lymph node metastasis...

Detailed pathologic studies over the past decade suggest a distal fallopian tube origin for the majority of "ovarian" high-grade serous carcinomas (HGSC). This review will summarize molecular alterations observed in tubal precursors for HGSC, namely p53 signatures and serous tubal intraepithelial carcinomas, and in nonmalignant fallopian tube epithelial cells obtained from women at increased genetic risk for HGSC. Recent experiments investigating the impact of follicular fluid exposure and retrograde menstruation on tumor development in the fallopian tube will also be discussed...

Hedgehog signaling pathway has been implicated in the pathology of ovarian cancer, and Survivin (BIRC5) has been suggested as a novel target of this pathway. Herein we investigated the role of Hedgehog signaling pathway and Survivin in ovarian carcinoma and borderline tumor samples. We aimed to determine possible ways of pathway modulation on primary ovarian cancer cells and an established cell line. RNA was extracted from fresh tumors and control tissues and gene expression was examined using qRT-PCR. Pathway activity in cell lines was examined after treatment with cyclopamine, SHH protein, GANT-61 or lithium chloride using qRT-PCR, western blot and confocal microscopy...

Rates of blood transfusion are reported as high as 32% in women undergoing major gynecologic cancer surgery. Therefore, care of the gynecologic oncology patient who refuses blood products, such as Jehovah's witnesses, can pose a unique challenge. The objective of this study was to determine rate of adverse post-operative outcomes within 30 days of surgery in Jehovah's witnesses with gynecologic cancer. This was a retrospective cohort study of Jehovah's witnesses undergoing laparotomy or minimally invasive surgery (MIS) for gynecologic cancer at a single institution...

Ovarian carcinomas were formerly referred to as "surface epithelial carcinomas," reflecting the belief that they all arise from the ovarian surface epithelium. It is now appreciated that most ovarian carcinomas originate from either fallopian tube or endometriotic epithelium, and how we approach prevention will thus differ between histotypes. The 5 histotypes of ovarian carcinoma (high-grade serous, clear cell, endometrioid, mucinous, and low-grade serous, in descending order of frequency) can be reproducibly diagnosed, and are distinct disease entities, differing with respect to genetic risk factors, molecular events during oncogenesis, patterns of spread, and response to chemotherapy...

A paradigm shift of the origin of ovarian cancer to fallopian tube has brought more focus on bilateral salpingectomy as a preventive method for ovarian cancer. Bilateral salpingectomy has shown a dramatic reduction in the risk of ovarian cancer. Bilateral salpingo-oophorectomy has been a long-used practice to prevent ovarian cancer, but it brings surgical menopause and an increased mortality rate to women undergoing such a surgery at the age of <47.5. With the prophylactic bilateral salpingectomy, however, the ovarian function remains unaltered...

OBJECTIVE: Ovarian cancer is the fifth most common cancer in women and one of the leading causes of death from gynecological malignancies. Despite of its clinical importance, ovarian tumorigenesis is poorly understood and prognosis remains poor. This is particularly true for the most common type of ovarian cancer, high-grade serous ovarian cancer. RESULTS: Two models are considered, whether it arises from the ovarian surface epithelium or from the fallopian tube...

Sterilization is the most common form of contraception used worldwide and is highly effective in preventing unintended pregnancy. Each of the available sterilization methods has unique advantages and disadvantages that influence the choice of approach for each individual patient. Salpingectomy for sterilization has become more popular in recent years, with mounting evidence suggesting a protective effect against ovarian cancers originating in the fallopian tube. At the same time, Essure hysteroscopic sterilization has come under scrutiny because of increasing reports of possible adverse effects associated with its use...
