BACKGROUND: Retroperitoneal high-grade serous carcinoma (HGSC) is extremely rare and the origin remains unclear. We present a case of retroperitoneal HGSC and coexisting serous tubal intraepithelial carcinoma (STIC), which is considered as the main origin of ovarian HGSC. We reviewed the available literature and discussed about the origin of this rare disease. CASE PRESENTATION: A 58-year-old female with a 93 × 65 × 62 mm-solid tumor with a cystic part was located immediately dorsal to the rectum underwent bilateral salpingo-oophorectomy, total abdominal hysterectomy, and en bloc resection of the retroperitoneal tumor together with lower anterior resection of the rectum...

The majority of extrauterine high-grade serous carcinomas are believed to arise in the fallopian tube as serous tubal intraepithelial carcinomas. The primary mode of metastasis is intraperitoneal, and patients usually present with peritoneal carcinomatosis. Although the tubes have a rich lymphatic network, tubal lymphatic invasion is observed in only a minority of cases. Fallopian tube sections from 222 patients with advanced stage high-grade extrauterine serous carcinoma were reviewed and lymphatic invasion within the lamina propria and myosalpinx were assessed...

BACKGROUND: High-grade serous carcinoma, a representative high-grade ovarian carcinoma, is believed to be closely associated with a TP53 mutation. Recently, this category of ovarian carcinoma has gained increasing attention owing to the recognition of morphological varieties of TP53-mutated high-grade ovarian carcinoma. Herein, we report the case of a patient with high-grade serous carcinoma with mucinous differentiation. CASE PRESENTATION: A 59-year-old postmenopausal woman was referred to the gynecologist because of abnormal vaginal bleeding...

Recent insights supporting the fallopian tube epithelium (FTE) and serous tubal intraepithelial carcinomas (STIC) as the tissue of origin and the precursor lesion, respectively, for the majority of high-grade serous ovarian carcinomas (HGSOC) provide the necessary context to study the mechanisms that drive the development and progression of HGSOC. Here we investigate the role of the E3 ubiquitin ligase RNF20 and histone H2B monoubiquitylation (H2Bub1) in serous tumorigenesis and report that heterozygous loss of RNF20 defines the majority of HGSOC tumors...

The clonal relationship between ovarian high-grade serous carcinoma (HGSC) and its presumed precursor lesion, serous tubal intraepithelial carcinoma (STIC), has been reported. However, when analyzing patients with concurrent ovarian carcinoma and tubal lesion, the extensive carcinoma tissues present at diagnosis may have effaced the natural habitat of precursor clone(s), obscuring tumor clonal evolutionary history, or may have disseminated to anatomically adjacent fimbriae ends, masquerading as precursor lesions...

There is growing evidence that the majority of high-grade serous ovarian carcinomas likely arise from local dissemination of precursor lesions of the fallopian tube. Evolution of these lesions from early "p53 signatures" to latter-stage, serous tubal intraepithelial carcinomas (STICs) is characterized by cytologic atypia, accumulation of somatic mutations, and genomic instability, the etiologies of which remain unclear. Long interspersed element 1 (LINE-1) retrotransposon is expressed in many carcinomas, including high-grade serous ovarian carcinoma, where it contributes to genomic instability; however, the timing of LINE-1 activation during this evolution has yet to be elucidated...

Background: BRCA gene mutations significantly increase the risk of breast and ovarian cancers where the lifetime risk of the ovarian cancer is about 40%. Therefore, many women with such mutations undergo prophylactic bilateral mastectomy and salpingo-oophorectomy. About 5-6% of these individuals display occult carcinomas in tubo-ovarian locations of which over 85% are tubal in origin. The objective of this case study was to emphasize emergence of benign lesions mimicking cancer under these circumstances...

Ovarian cancer is a heterogeneous disease having the highest gynecologic fatality in the United States with a 5-year survival rate of 46.5%. Poor overall prognosis is mostly attributed to inadequate screening tools, and the majority of diagnoses occur at late stages of the disease. Due to genetic and biological underpinnings, ovarian high-grade serous carcinomas (HGSC) have etiologic evidence in the distal fallopian tube. Fallopian tube screening modalities are aggressively investigated, but few describe cytological characteristics of benign tubal specimens to help in the comparative detection of HGSC precursor cells...

BACKGROUND: Despite at the beginning known as a benign disease, endometriosis is defined as a risk factor for developing ovarian carcinoma. The effect of endometriosis on ovarian malignancy is known but its role in granulosa cell tumor is still unclear. METHODS AND MATERIALS: In this study, serum samples were collected from patients with endometriosis and divided into whole and steroid-depleted groups. Desertification was performed according to the charcoal-dextran protocol and sera were added to the culture media of granulosa cells retrieved from tubal or male factor infertile women...

Most ovarian carcinomas are high-grade serous carcinomas (HGSC) that contain TP53 mutations, present at advanced stage, and eventually become resistant to chemotherapy. The rapid evolution of this disease has been attributed to an origin in the distal fallopian tube, in the form of serous tubal intraepithelial carcinomas (STICs). This has led to a disease model where malignancy develops first in the tube and spreads to the peritoneum or regional lymph nodes. However, although most early or incidentally discovered HGSCs manifest in the tube with STICs, many advanced HGSCs are not accompanied by a malignancy in the fimbria...

Beginning with the discovery of the BRCA -associated ovarian cancer susceptibility genes and subsequent detailed examination of risk-reducing salpingo-oophorectomy (RRSO) specimens, a new paradigm of ovarian carcinogenesis has unfolded with attention to the distal fallopian tube. The primary focus has been an early cancer or neoplasm in the fallopian tube which is seen in virtually all incidentally discovered high-grade serous cancers in asymptomatic women. This high-frequency of tubal involvement in early serous neoplasm (usually in the form of serous tubal intraepithelial carcinoma-STIC) has galvanized attention to this organ as a primary source of this disease...

High-grade serous ovarian cancer, also known as high-grade serous carcinoma (HGSC), is the most common and deadliest type of ovarian cancer. HGSC appears to arise from the ovary, fallopian tube, or peritoneum. As most HGSC cases present with widespread peritoneal metastases, it is often not clear where HGSC truly originates. Traditionally, the ovarian surface epithelium (OSE) was long believed to be the origin of HGSC. Since the late 1990s, the fallopian tube epithelium has emerged as a potential primary origin of HGSC...

This article summarizes the pathogenesis of ovarian carcinoma, focusing on the paradox of high-grade serous carcinogenesis. The fallopian tube is the prime site of origin in early serous cancers. Because a subset of serous cancers is associated with early serous proliferations absent intramucosal carcinomas, "precursor escape" is emerging, whereby some advanced cancers trace their roots to early serous proliferations. This has parallels in the endometriosis model and opens up a novel mechanism by which advanced malignancy could emerge without an obvious tubal carcinoma...

Serous tubal intraepithelial carcinoma (STIC) has attracted attention as a precursor lesion of high-grade serous carcinoma (HGSC) of the ovary. We report the rare case of a woman in whom adenocarcinoma cells were detected in cervical smears and demonstrated to be derived from STIC in the fimbria. The patient was a 48-year-old woman, in whom cervical smears contained adenocarcinoma cells, but cervical conization did not reveal adenocarcinoma. Because the post-conization smears again demonstrated adenocarcinoma cells, hysterectomy with bilateral salpingectomy was performed 16 months after the first detection of adenocarcinoma cells in cervical smears...

The prognosis of women diagnosed with invasive high-grade serous ovarian carcinoma (HGSC) is poor. More information about serous tubal intraepithelial carcinoma (STIC) and serous tubal intraepithelial lesions (STIL), putative precursor lesions of HGSC, could inform prevention efforts. We conducted a multicenter study to identify risk/protective factors associated with STIC/STILs and characterize p53 signatures in the fallopian tube. The fallopian tubes and ovaries of 479 high-risk women ≥30 years of age who underwent bilateral risk-reducing salpingo-oophorectomy were reviewed for invasive cancer/STICs/STILs...

OBJECTIVE: Primary objective of this study was to determine prognostic significance of Bohm's histopathological regression score in patients who received neoadjuvant chemotherapy (NACT) for treatment of high grade serous (HGS) tubal & ovarian carcinoma. METHODS: This was a retrospective cohort study of patients who received NACT between 2010 and 2015. The 3 point histopathological regression score of Böhm was used to classify chemotherapy response. Survival outcomes between the 3 different subgroups was analysed and compared with standard clinico-pathological variables using the Cox proportional hazards model and log-rank test...

Purpose: High-grade serous ovarian carcinoma (HGSOC) typically remains undiagnosed until advanced stages when peritoneal dissemination has already occurred. Here, we sought to identify HGSOC-specific alterations in DNA methylation and assess their potential to provide sensitive and specific detection of HGSOC at its earliest stages. Experimental Design: MethylationEPIC genome-wide methylation analysis was performed on a discovery cohort comprising 23 HGSOC, 37 non-HGSOC malignant, and 36 histologically unremarkable gynecologic tissue samples...

OBJECTIVES: The aim of this study was to investigate the distribution of primary cilia on secretory cells in normal fallopian tube (FT) and serous tubal intraepithelial carcinoma (STIC). METHODS: Fallopian tube tissue samples were obtained from 4 females undergoing prophylactic hysterectomies and 6 patients diagnosed with STIC. A mogp-TAg transgenic mouse STIC sample was also compared with a wild-type mouse FT sample. Serous tubal intraepithelial carcinoma was identified by hematoxylin and eosin staining and confirmed by positive Ki-67 and p53 immunohistochemical staining of tissue sections...
