BACKGROUND Human Papilloma Virus (HPV)-associated Vulvar Squamous Cell Carcinomas (VSCC) present more frequently in young women than HPV- independent tumors. Due to its association with HPV infection, the incidence of vulvar cancer is increasing in young women; however, during pregnancy, it is still extremely rare. CASE REPORT We present the case of a 36-year-old pregnant woman at 23 weeks of pregnancy, diagnosed with HPV 16-associated VSCC, Federation of Gynecology and Obstetrics (FIGO) stage IB.

Subjecting a pregnant woman to violence can have negative effects on both the mother as well as the child. In Poland, there are programs, such as the Blue Card, aimed at protection against violence, however the phenomenon is underestimated.
View Article and Find Full Text PDFOvarian cancer (OC) is one of the biggest problems in gynecological oncology and is one of the most lethal cancers in women worldwide. Most patients with OC are diagnosed at an advanced stage; therefore, there is an urgent need to find new biomarkers for this disease. Gene expression profiling is proving to be a very effective tool for exploring new molecular markers for OC patients, although the relationship between such markers and patient survival and clinical outcomes is still elusive.

Ovarian reserve was analyzed by anti-Mullerian hormone (AMH) level.

Here, we reveal and compare pro-cancerous activity of spontaneously and drug-inducible senescent ovarian cancer cells. Experiments were performed on tumors and tumor-derived primary epithelial ovarian cancer cells (pEOCs) that were obtained from chemotherapy-naïve patients and from patients who received carboplatin (CPT) and paclitaxel (PCT) before cytoreduction.
View Article and Find Full Text PDFAlthough malignant ascites (MAs) are known to contribute to various aspects of ovarian cancer progression, knowledge regarding their role in the adhesion of cancer cells to normal peritoneal cells is incomplete. Here, we compared the effect of MAs and benign ascites (BAs) on the adhesion of A2780 and OVCAR-3 cancer cells to omentum-derived peritoneal mesothelial cells (PMCs) and peritoneal fibroblasts (PFBs). The results showed that MAs stimulated the adhesion of A2780 and OVCAR-3 cells to PMCs and PFBs more efficiently than did BAs, and the strongest binding occurred when both cancer and normal cells were exposed to the fluid.

Recently, the triggers and molecular events underlying spontaneous, replicative senescence of primary epithelial ovarian cancer cells were characterized. In this study, we reanalyzed tumors obtained from ovarian cancer patients with respect to the expression of the senescence biomarkers SA-β-Gal and γ-H2A.

Here we comprehensively characterize this process in primary epithelial ovarian cancer cells (pEOCs). Analysis of tumors from ovarian cancer patients showed an abundance of senescent cells in vivo.
View Article and Find Full Text PDFObjectives: The study's main aim was to evaluate the relationship between the performance of predictive models for differential diagnoses of ovarian tumors and levels of diagnostic confidence in subjective assessment (SA) with ultrasound. The second aim was to identify the parameters that differentiate between malignant and benign tumors among tumors initially diagnosed as uncertain by SA.
Methods: The study included 250 (55%) benign ovarian masses and 201 (45%) malignant tumors.
Approximately, 5% of ovarian tumors have hormonal activity. Steroid cell tumors (SCTs) represent about 0.1% of all ovarian tumors.

Here we examined whether this phenomenon may be determined by an expression of intercellular junctions in peritoneal mesothelial cells (PMCs). Analysis of ovarian tumors showed that cancer cells are localized below an intact layer of PMCs.

We performed an analysis of the correlation of PDGFRs expression and stage of the disease, tumor grade and histopathological type of epithelial ovarian cancer (EOC). Additionally, we evaluated patient prognosis according to PDGFR expression.
View Article and Find Full Text PDFThe role of the epithelial-mesenchymal transition (EMT) in ovarian cancer cell progression is unquestioned. In this report, we describe that malignant ascites, fluid that accumulates in the peritoneal cavity in a large group of patients with ovarian cancer, stimulate EMT in two representative ovarian cancer cell lines (A2780, SKOV-3). In addition, we identify the ascites-derived mediators of EMT and signaling pathways initiated in the cancer cells that underlie this phenomenon.
View Article and Find Full Text PDFVery little is known about the mechanisms by which malignant ascites modulates the cancer-promoting activity of human peritoneal mesothelial cells (HPMCs). Because malignant ascites induces pro-tumoral senescence in HPMCs, here we examined if this effect could be driven by oxidative stress. The study showed that malignant ascites generated by serous ovarian tumors induced oxidative damage to the DNA (γH2A.

Angiogenesis was analyzed according to expression of CD31, CD34, and connexin 43. Proliferation and migration of endothelial cells were tested using fluorescence-based methods.

It typically presents as severe hyperandrogenism and/or virilization in postmenopausal woman. Here we describe a 66-year old woman with presentation of severe hirsutism, alopecia, clitoromegaly and laboratory finding of significantly elevated serum total testosterone concentration and hyperinsulinemia.

The exact nature of the interactions between malignant ascitic fluids and peritoneal mesothelial cells (HPMCs) in ovarian cancer progression has so far remained elusive. Here we assessed whether malignant ascitic fluids may promote the senescence of HPMCs and, by doing so, enhance the acquisition of their pro-cancerogenic phenotype.

This report was aimed at investigating whether the high aggressiveness of undifferentiated ovarian cancer may be associated with a biochemical composition of malignant ascites accumulating in the peritoneal cavity. We analyzed ascites from patients with undifferentiated, high-grade serous, endometrioid and clear-cell ovarian cancers, and from non-cancerous patients with respect to a group of soluble agents involved in cancer cell progression.

Objectives: Subjective ultrasonographic assessment is currently considered to be the best method of differentiation between various types of ovarian tumors. The aim of the study was to evaluate selected ultrasonographic features and CA125 levels of hormonally active ovarian tumors.
Material And Methods: A total of 1135 women with ovarian tumors were diagnosed between 2006 and 2014 at the Division of Gynecologic Surgery, Poznan University of Medical Sciences.
Aim Of The Study: To investigate whether serum levels of VEGF, bFGF and endoglin correlate with tumor VEGF and bFGF expression or microvessel density (MVD) in ovarian cancer.
Patients And Methods: Forty five patients with epithelial ovarian cancers (EOCs) and 38 patients with benign ovarian tumors (BOTs) were included into the study. Serum levels of VEGF, bFGF and endoglin were assessed using ELISA.
Thecoma is a rare ovarian tumor, presenting usually in postmenopausal women as unilateral, benign, solid lesion. About 15% of affected patients develop endometrial hyperplasia (EH) and 20% are diagnosed with endometrial cancer. In this case report, we present 60-year-old women admitted because of recurrent spotting of 5 years duration, which started 1 year after menopause.

Case Report: A 47-year-old woman was admitted to the Department of Thoracosurgery due to pulmonary lesions suspected to be metastatic. The potential primary site of the neoplasm was not identified by previous imaging studies and specialist counseling.
Objectives: The aim of this study was to externally validate the diagnostic performance of the International Ovarian Tumor Analysis logistic regression models (LR1 and LR2, 2005) and other popular prognostic models including the Timmerman logistic regression model (1999), the Alcazar model (2003), the risk of malignancy index (RMI, 1990), and the risk of malignancy algorithm (ROMA, 2009). We compared these models to subjective ultrasonographic assessment performed by an experienced ultrasonography specialist, and with our previously developed scales: the sonomorphologic index and the vascularization index. Furthermore, we evaluated diagnostic tests with regard to the menopausal status of patients.
