Serous ovarian neoplasms can overlap morphologically with peritoneal mesothelial proliferations, with common features including well-differentiated papillary mesothelioma (WDPM) and malignant epithelioid mesothelioma (MM). Accurate histologic classification of these neoplasms is important for clinical management. The Pax-8 protein is commonly used for differentiating peritoneal MM from serous carcinoma, but the diagnostic value of Pax-8 for distinguishing WDPM from borderline or low-grade serous tumors is unknown...

In this review, we outline the biology and management of patients with carcinosarcomas and related malignancies, which are often included under the broader concept of sarcomatoid carcinomas. Carcinosarcomas are unusual tumors that are commonly gynecologic in origin, where they are referred to as malignant mixed Müllerian tumors, but may appear in any anatomic site. Although a variety of hypotheses have been presented as to the biphasic nature of these tumors, carcinosarcomas seem to represent the best example in human cancers of the concept of epithelial-mesenchymal transition (EMT), in which the two parts of the tumor are genomically related to one another, as opposed to the mesenchymal component that represents a second neoplasm or (benign) reactive process...

PURPOSE: We hypothesized that mutations in homologous recombination repair (HRR) genes beyond BRCA1 and BRCA2 improve outcomes for ovarian carcinoma (OC) patients treated with platinum therapy and would impact the relative benefit of adding prolonged bevacizumab.  Experimental Design: We sequenced DNA from blood and/or neoplasm from 1,195 women enrolled in GOG-0218, a randomized phase III trial in advanced OC of bevacizumab added to carboplatin and paclitaxel. Defects in HRR were defined as damaging mutations in 16 genes...

BACKGROUND: Uterine leiomyomas represent the gynecological neoplasm with the highest prevalence worldwide. This apparently benign pathological entity may permeate into the venous system causing the so-called intravenous leiomyomatosis of the uterus (IVL). IVL may seldom extend to large caliber veins and reach the right cardiac chambers or pulmonary arteries and cause signs of right sided congestive heart failure and sudden death. Due to its low incidence, however, IVL with intracardiac extension is often misdiagnosed resulting in deferred treatment...

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but adhesions to the surrounding peritoneum were seen. Given the patient's age, large mass size, and accompanying uterine myoma and right ovarian cyst, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed...

Epithelial ovarian carcinoma is a high mortality neoplasm in gynecologic malignancy. It usually can metastasize to distant organs such as pleura, liver, lung, and lymph nodes. However, the skin metastases are not common and related to very poor prognosis. Here we report a 54-year-old patient with ovarian clear cell carcinoma with skin metastases on the anterior chest at 11 months after initial diagnosis. Although she received palliative chemotherapy, she expired due to disease progression 2 months later after the diagnosis of skin metastases...

Gynaecological malignancies contribute significantly to cancer burden and have a higher rate of mortality and morbidity. The aim of this retrospective study was to determine the pattern of gynaecological malignancies identified between January, 2000 and December, 2011, at the Centre for Nuclear Medicine and Radiotherapy (CENAR). At CENAR 5,072 female patients were registered with different malignancies, of which 632 cases were gynaecological malignancies. Ovarian cancer (47%) was the most common gynaecological malignancy, followed by cervical cancer (29%), uterine cancer (14%), vulvar and vaginal cancer (6%), and gestational trophoblastic neoplasm (4%)...

BACKGROUND: Mature cystic teratomas are the most common ovarian neoplasm in adolescents. They are typically benign, however malignant transformation rarely occurs. We report a low-grade astrocytoma arising from a mature cystic teratoma in an adolescent patient. CASE: The patient was a 12-year-old female with an asymptomatic ovarian cyst and subsequent cystectomy. Final pathology identified a solid tumor with glial tissue within the cyst, reported as low-grade astrocytoma arising in a mature cystic teratoma...

AIMS: Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm of fibroblastic origin, first described as a tumor of the pleura and now well established at extrapleural sites. However, SFT in the female genital tract is rare and therefore not fully characterized. MATERIAL AND RESULTS: We describe a series of 25 SFTs arising throughout the gynecologic tract, including vulva (14 cases), vagina (1), cervix (1), uterus (6), ovary (2) and fallopian tube (1)...

Endometrial cancer is the fourth cause of cancer in women in France and is the second most common cancer of the gynecologic cancer after breast cancer with 7275 new cases in 2012. The incidence of this neoplasm tends to increase with population aging, diabetes and obesity's augmentation. In rare cases, a hereditary factor has been described: Lynch's syndrome. The therapeutic management of the patient depends on the endometrial biopsy which specifies the histological type and the histo-prognostic grade as well as the MRI which allow the tumor staging...

PURPOSE: The ASCO value framework allows physicians and patients to compare the relative value of novel treatments. Our aim was to assess the value of three frontline ovarian cancer therapies by using this framework. METHODS: From phase III, randomized controlled clinical trial (RCT) data, the net health benefits (NHBs) for three frontline ovarian cancer treatment options-dose-dense paclitaxel (Japanese Gynecologic Oncology Group study JGOG 3016), intraperitoneal (IP)/intravenous (IV) chemotherapy (Gynecologic Oncology Group [GOG] study GOG 172), and concurrent plus maintenance bevacizumab (GOG 218 and the Seventh International Collaborative Ovarian Neoplasm study [ICON7])-were calculated...

Epithelial ovarian neoplasms are a heterogeneous group of tumors, including various malignancies with distinct clinicopathologic and molecular features. Mutations in BRAF and KRAS genes are the most frequent genetic aberrations found in low-grade serous ovarian carcinomas and serous and mucinous borderline tumors. Implementation of targeted therapeutic strategies requires access to highly specific and highly sensitive diagnostic tests for rapid determination of mutation status. One candidate for such test is fully integrated, real-time polymerase chain reaction-based Idylla™ system for quick and simple detection of KRAS mutations in formaldehyde fixed-paraffin embedded tumor samples...

OBJECTIVE: Extramammary Paget disease of the vulva (EPDV) is a rare occurrence with an indolent and relapsing course. Progression to invasion occurs in 4% to 19% of cases. The aim of this study is to report clinical-pathological features and outcomes of patients treated for invasive EPDV. METHODS: Data of consecutive patients treated between 2000 and 2017 for invasive EPDV were reviewed. RESULTS: Among 79 patients with EPDV, 10 (12.7%) presented a microinvasive or invasive form at first diagnosis or during follow-up...

INTRODUCTION: In selected cases, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an established treatment for patients suffering from peritoneal metastases from colorectal, ovarian, gastric or appendiceal origin. The effectiveness of this extensive has not been elucidated within other rare diseases by now. METHODS: We conducted a retrospective analysis of patients treated with CRS for peritoneal carcinomatosis during the period between July 2010 and September 2015...

Ovarian cancer (OC) is the most deadly gynecological cancer and unlike most other neoplasms, survival rates for OC have not significantly improved in recent decades. We show that RAD6, an ubiquitin-conjugating enzyme, is significantly overexpressed in ovarian tumors and its expression increases in response to carboplatin chemotherapy. RAD6 expression correlated strongly with acquired chemoresistance and malignant behavior of OC cells, expression of stem cell genes and poor prognosis of OC patients, suggesting an important role for RAD6 in ovarian tumor progression...

OBJECTIVE: Lymph node metastasis has been shown to represent the most significant prognostic factor in vulvar carcinoma. Because only 25% to 35% of patients with early stage disease have lymph node metastases, a significant 65% to 75% possibly do not benefit from elective inguinofemoral lymphadenectomy considering the related morbidities of wound infection, breakdown, and lower limb lymphedema. This review article aims to present and summarize the evidence available with regard to sentinel lymph node (SLN)-guided management of vulvar carcinoma...

JUSTIFICATION AND OBJECTIVES: Patients affected by gynecological or gastrointestinal tract neoplasms that evolve to peritoneal carcinomatosis experience a significant drop in their quality of life, high morbidity and short survival times with currently available chemotherapeutic schemes. The surgical treatment based on cytoreduction and the employment of hyperthermic intraperitoneal chemotherapy in the intra-operative period is a true challenge to anesthesiologist. CASE REPORT: A 67 years old patient diagnosed with mucinous adenocarcinoma of the Appendix associated with mucinous carcinomatosis, was submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), under general anesthesia and epidural block...

Ovarian cancer is the most lethal gynecological malignancy in the world. Our previous studies showed that mangiferin, purified from plant source, possessed anti-neoplasm effect on human lung adenocarcinoma A549 cells. This study aimed to determine the apoptosis-inducing effect of mangiferin on human ovarian carcinoma OVCAR3 cells. By in vitro studies, we found mangiferin significantly inhibited viability of OVCAR3 cells, and remarkably increased the sensitivity of OVCAR3 cells to cisplatin. In addition, the activation of caspase-dependent apoptosis was observed in mangiferin treated ovarian cancer cells...
