Cancer Antigen 125 Levels are Significantly Associated With Prognostic Parameters in Uterine Papillary Serous Carcinoma.

Uterine papillary serous carcinoma (UPSC) is a highly aggressive subtype of endometrial carcinoma. Histopathologically, it resembles the pattern of serous papillary carcinoma of the ovary. Cancer antigen 125 (CA-125) is the most widely used biomarker in epithelial ovarian carcinoma. Its use in UPSC evaluation has yet to be determined. The purpose of this study was to investigate the significance of preoperative serum CA-125 as a prognostic factor in patients with UPSC.

Mechanisms of resistance to HER2-targeted therapies in HER2-amplified uterine serous carcinoma, and strategies to overcome it.

Uterine serous carcinoma (USC) is an aggressive subtype of endometrial cancer that accounts for up to 40% of all endometrial cancer-related deaths. Recent whole-exome sequencing studies have revealed HER2/neu amplification in 27-44% of USC patients, supporting HER2 as an attractive pathway for target therapies based on monoclonal antibodies or tyrosine kinase inhibitors. Preclinical studies and a recently published prospective randomized trial with trastuzumab in combination with chemotherapy demonstrated p...

Issues in the Differential Diagnosis of Uterine Low-grade Endometrioid Carcinoma, Including Mixed Endometrial Carcinomas: Recommendations from the International Society of Gynecological Pathologists.

This article provides practical recommendations developed from the International Society of Gynecological Pathologists Endometrial Carcinoma Project to address 4 issues that may arise in the diagnosis of uterine corpus low-grade endometrioid carcinoma: (1) The distinction between atypical hyperplasia and low-grade endometrioid carcinoma. (2) The distinction between low-grade endometrioid carcinoma and serous carcinoma. (3) The distinction between corded and hyalinized or spindle cell variants of low-grade e...

Low grade serous ovarian carcinoma: identifying variations in practice patterns.

Low grade serous ovarian carcinoma is a rare subtype of ovarian cancer with an indolent and chemorefractory course. As such, treatment strategies among practitioners are not uniformly known. The primary objective of this study was to identify differences in practice patterns among physicians who treat low grade serous carcinoma.

GATA6: a new predictor for prognosis in ovarian Cancer.

Ovarian cancer (OC) is the main cause of gynecological cancer-associated mortality. Improving the diagnosis is important for guiding clinical treatment. The present study aimed to investigate the relationship between expression of GATA6, a stem cell factor, and its prognosis in OC. In total, 521 OC cases were included. Immunohistochemistry analysis demonstrated that GATA6 was expressed in both high grade serous carcinoma as well as non-serous tumors. High grade serous carcinoma showed a higher percentage of...

High grade serous intraepithelial carcinoma arising in a benign ovarian serous cyst - a bridge too far?

Uterine and Tubal Lavage for Earlier Cancer Detection Using an Innovative Catheter: A Feasibility and Safety Study.

Poor survival of high-grade serous pelvic cancer is caused by a lack of effective screening measures. The detection of exfoliated cells from high-grade serous pelvic cancer, or precursor lesions, is a promising concept for earlier diagnosis. However, collecting those cells in the most efficient way while fulfilling all requirements for a screening approach is a challenge. We introduce a new catheter for uterine and tubal lavage (UtL) and the clinical evaluation of its performance.

Late recurrence of pStage 1 low-grade serous ovarian tumor presenting as a symptomatic bone metastasis: a case report.

Ovarian serous borderline tumor/atypical proliferative serous tumor (SBT/APST) is characterized by presenting at an early stage and much longer survival than high-grade serous carcinoma. Given that the prognosis of ovarian SBT/APST with no invasive features is excellent, remote relapse after surgery can pose a diagnostic pitfall. Bone metastasis as transformed low-grade carcinoma is an extremely rare initial presentation of recurrence in patients whose primary tumor was confined to the ovaries.

Histotype classification of ovarian carcinoma: A comparison of approaches.

Major changes in the classification of ovarian carcinoma histotypes occurred over the last two decades, resulting in the current 2014 World Health Organization (WHO) diagnostic criteria that recognize five principal histotypes: high-grade serous, low-grade serous, endometrioid, clear cell, and mucinous carcinoma. We assessed the impact of these guidelines and use of immunohistochemical (IHC) markers on classification of ovarian carcinomas in existing population-based studies.

Ovarian neuroendocrine carcinoma of metastatic origin: clues for diagnosis.

Neuroendocrine tumors of the ovary are rare and of uncertain histogenesis. They may be primary or metastatic. Pathogenesis of ovarian carcinomas remains unknown. We report the case of an ovarian large cell carcinoma expressing all neuroendocrine markers (CD56, Chromogranin A, Synaptophysin) that presented as a primary tumor and coexisted with a typical endometrial serous carcinoma also expressing one neuroendocrine marker (CD56). The two tumors had identical molecular mutational profiles, as examined by Nex...

Risk of high-grade serous ovarian cancer associated with pelvic inflammatory disease, parity and breast cancer.

Ovarian carcinoma is not a single disease, but rather a collection of subtypes with differing molecular properties and risk profiles. The most common of these, and the subject of this work, is high-grade serous ovarian carcinoma (HGSC).

Serous Neoplasms of the Pancreas: A Comprehensive Review.

Serous neoplasms are uncommon, usually cystic tumors that account for less than 1% of all primary pancreatic lesions. They consist predominantly of a monomorphic epithelial cell population with a glycogen-rich, clear cytoplasm, reminiscent of clear cell renal cell carcinoma, with which serous neoplasms share an association with underlying VHL loss-of-function mutations. Serous neoplasms have no metastatic potential. Accurate recognition of this entity, including its various architectural subtypes, is critic...

Expression of UCP2 is associated with sensitivity to platinum-based chemotherapy for ovarian serous carcinoma.

The standard treatment for ovarian serous carcinoma is maximum debulking surgery and platinum-based chemotherapy. Despite the high response rate for chemotherapy, the majority of patients will be resistant to first-line agents and the prognosis for these patients is particularly poor. Currently there are no reliable methods to determine or predict platinum resistance. Uncoupling protein 2 (UCP2) is widely expressed in cancer cells and regulates the production of mitochondrial reactive oxygen species (ROS). ...

Morphology and tumor-infiltrating lymphocytes in high-stage, high-grade serous ovarian carcinoma correlated with long-term survival.

Advanced-stage ovarian high-grade serous carcinoma (HGSC) is a poor-prognosis cancer, however a small and poorly characterized subset of patients shows long-term survival. We aimed to establish a cohort of HGSC long-term survivors for histopathological and molecular analysis.

Uterine Carcinosarcomas - Diagnosis and Management.

Uterine carcinosarcomas are rare tumors that account for less than 5% of all uterine malignancies. These tumors (previously called malignant mixed Müllerian tumors) are dedifferentiated carcinomas that comprise carcinomatous and sarcomatous elements and arise from a single malignant clone. They are considered a high-risk variant of endometrial adenocarcinoma because carcinosarcomas share more similarities in epidemiology, risk factors, and clinical behavior with endometrial carcinoma than with uterine sarc...

Lymphoepithelioma-Like Carcinoma of the Uterine Cervix: A Pathologic Study of Eight Cases With Emphasis on the Association With Human Papillomavirus.

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is a rare tumor. The goal of this study was to evaluate a series of cases of cervical LELC and to investigate possible association with human papillomavirus (HPV) and/or Epstein-Barr virus (EBV).

Serous papillary peritoneal carcinoma diagnosed by pleural biopsy.

The Effect of Fucoidan, a Potential New, Natural, Anti-Neoplastic Agent on Uterine Sarcomas and Carcinosarcoma Cell Lines: ENITEC Collaborative Study.

The aim of the study was to assess the activity of fucoidan on the uterine sarcomas (MES-SA and ESS-1) and carcinosarcoma cell lines (SK-UT-1 and SK-UT-1B) and its toxicity on the human skin fibroblasts (HSF). Two uterine sarcomas and two carcinosarcoma cell lines were examined, as a control HSF were used. Cell viability was assessed with MTT test, apoptosis with caspase-3 activity and cell cycle by assessment of DNA synthesis. Fucoidan significantly decreases cell viability in SK-UT-1, SK-UT-1B, and ESS-1 ...

Radiation-Induced Uterine Carcinosarcoma after Concurrent Chemoradiotherapy for Cervical Squamous Cell Carcinoma.

 To describe a case of radiation-induced uterine carcinosarcoma 6 years after a cervical squamous cell carcinoma treatment, which imposed some diagnostic and management challenges.

Activity and clinical relevance of autotaxin and lysophosphatidic acid pathways in high-grade serous carcinoma.

The aim of this study was to analyze the expression, biological role and clinical relevance of autotaxin (ATX), the enzyme synthetizing lysophosphatidic acid (LPA), and LPA receptors (LPAR) in high-grade serous carcinoma (HGSC). mRNA expression by qRT-PCR of LPAR1-6 was analyzed in 155 HGSC specimens (88 effusions, 67 solid lesions). ATX mRNA expression was analyzed in 97 specimens. ATX, ERK, and AKT protein expression was studied by Western blotting. LPAR2 mRNA was overexpressed in HGSC cells in effusions ...

Pulmonary metastasis of mesonephric-like adenocarcinoma arising from the uterine body: a striking mimicry of follicular thyroid carcinoma.

Mesonephric adenocarcinoma (MNAC) is a rare neoplasm that presumably develops from the mesonephric remnants, occurring mostly in the uterine cervix and, to a lesser extent, the vagina, uterine body, ovary, and para-adnexal soft tissues. Histologically, MNAC exhibits a variety of architectural growth patterns, even within the same tumour, including tubular, glandular, papillary, solid, and retiform, and therefore may be confused with more common carcinomas of Müllerian origin. Moreover, the tubules with lum...

Molecular Genetics of Endometrial Carcinoma.

Endometrial cancer is the most commonly diagnosed gynecologic malignancy in the United States. Endometrioid endometrial carcinomas constitute approximately 85% of newly diagnosed cases; serous carcinomas represent approximately 3-10% of diagnoses; clear cell carcinoma accounts for

Uterine and ovary blood flow after uterine desarterialization

The aim of this article is to compare the effect of uterine desarterialization (UD) and hypogastric arteries ligature (HAL) in uterine and ovarian blood flow indirectly measured with the pulsatility index (PI).

What Should a Gynecologist Know about Li-Fraumeni Syndrome? Lessons from a Patient Undergoing Hysterectomy for Benign Indications.

Li-Fraumeni syndrome (LFS) is a rare highly penetrant cancer syndrome characterized by mutation in the TP53 tumor suppressor gene. Recent data suggest that this germline mutation is more frequent than once thought. While LFS has not been associated previously with pelvic serous carcinoma, gynecologic malignancies have been reported in this patient population. We present the case report of a 37-year-old patient with known LFS and a history of multiple cancers who underwent total abdominal hysterectomy for be...

The road to long-term survival: Surgical approach and longitudinal treatments of long-term survivors of advanced-stage serous ovarian cancer.

It is unclear if the types of surgical procedures performed on long-term survivors (LTS) of high-grade serous ovarian carcinoma (HGSOC) contribute to prolonged survival. In this case-control study we review the surgical procedures performed on LTS and describe their individual longitudinal disease courses.
