Ovarian cancer as the most fatal gynecological malignancy is often manifested by excessive fluid accumulation known as ascites or effusion. Ascites-derived microRNAs (miRNAs) may be closely associated with ovarian cancer progression. However, our knowledge of their roles, altered expression, and clinical outcomes remained limited. In this study, large-scale expression profiling of 754 human miRNAs was performed using real-time quantitative polymerase chain reaction and 384-well TaqMan array human miRNA A and B cards to identify differentially expressed miRNAs between extracellular fraction of the ascitic fluid associated with high-grade serous ovarian carcinomas and control plasma...

Ovarian carcinoma continues to be a concern for woman and maintains significant morbidity and mortality. Emerging molecular markers are providing additional opportunities for effective diagnosis and prognosis of disease. An integrated clinicopathologic and molecular classification of gynecologic malignancies has the potential to refine the clinical risk prediction of patients with cancer and to provide more tailored treatment recommendations.

RATIONALE: Malignant transformations of ovarian mature cystic teratomas (MCTs) occur rarely, especially in young women. Although it is extremely difficult to diagnose them, serum tumor marker level testing in combination with the use of imaging techniques may be useful in preoperative diagnosis. PATIENT CONCERNS: We present the case of a 31-year-old Chinese woman with the malignant transformation of an ovarian MCT. The patient had a history of oophorocystectomy due to an MCT of the right ovary 6 years prior and a gemellary pregnancy owing to in vitro fertilization and embryo transfer...

BACKGROUND: Cervical cancer is the most common malignancy from the female reproductive tract, and usually develops from low-grade or high-grade squamous intraepithelial lesions (LSIL or HSIL). Detecting the precancerous lesion during the LSIL-HSIL-invasive cancer sequelae can effectively interrupt the oncogenesis and decrease the incidence of invasive carcinoma. The aim of this study is to evaluate the performance of P16/Ki67 dual staining in triaging hr-HPV-positive population. METHODS: Conventional gynecological examination, cervical cytology and hr-HPV testing were given to all patients...

Endometrial carcinoma (EC) is one of the most common gynecological malignancies. The malignant degree increases between grade (G)1 and G3, and EC of G3 usually presents a high recurrence rate and poor prognosis. Therefore, the present study aimed to examine the principal genes associated with the degree of differentiation in EC. The microarrays GSE17025, GSE24537 and GSE35784, representing data of Type I EC samples of G1 and G3, were downloaded from the Gene Expression Omnibus. The differentially expressed genes (DEGs) and differentially expressed micro (mi)RNAs (DEMs) were identified, followed by functional enrichment analyses and interaction network construction...

MicroRNAs (miRNAs) play important roles in gene regulation, and their dysregulation is associated with many diseases including epithelial ovarian cancer (EOC). In this study, we determined the expression and function of miR-590-3p in EOC. miR-590-3p levels were higher in high-grade carcinoma when compared to low-grade or tumors with low malignant potential. Interestingly, plasma levels of miR-590-3p were significantly higher in EOC patients than in subjects with benign gynecological disorders. Transient transfection of miR-590-3p mimics or stable transfection of mir-590 increased cell proliferation, migration, and invasion...

Epithelial ovarian cancer is a deadly gynecologic malignancy because of its late detection, usually after local and distant metastatic spread. These cancers develop resistance to traditional chemotherapeutic agents; therefore, the development of next-generation immunotherapeutic approaches may have a significant promise in improving outcomes. A novel immunotherapeutic approach utilizing combination radiation therapy (RT) with immunostimulatory cowpea mosaic virus (CPMV) was tested in a preclinical syngeneic mouse model of ovarian carcinoma...

There have been rapid and significant advances in diagnostic and predictive molecular techniques in recent years with profound impact on patient care. In situ hybridization (ISH) studies have become well entrenched in surgical pathology practice and their role in the evaluation of HER2 in breast carcinoma and their diagnostic utility in soft tissue pathology are well known. Fluorescent ISH is being increasingly used in other sites such as the head and neck and the gynecologic tract. Like most tests in surgical pathology, ISH studies require good quality tissue, correlation with clinical and histopathologic findings, and adherence to guidelines for optimal assay performance and interpretation...

Peritoneal biopsies (PB) and peritoneal washing (PW) are routine measures in abdominal staging of gynecological malignancies and are used particularly for the assessment of occult microscopic tumor spread to the peritoneal surface including the diaphragm. Cytological diaphragmatic smears (DS) have been suggested as a supplemental tool; however, they are not routinely taken and their usefulness is still unclear. The present study retrospectively evaluated whether DS provide an additional benefit over PB and PW for the detection of peritoneal malignancies in patients with gynecological cancer...

Sister Mary Joseph nodule (SMJN) is an uncommon pattern of superficial periumbilical tumor metastasis, with the primary tumor most commonly associated with gynecological or gastrointestinal origins. This manifestation can represent extensive tumor development from any of the intra-abdominal or pelvic structures. Therefore, SMJN carries a poor prognosis, with a two-year survival rate of only 13.5 percent regardless of the etiology of primary cancer. In this case, a 67-year-old man with metastatic mucinous adenocarcinoma of the appendix involving the umbilicus presenting more than five years after the initial cancer diagnosis is reported...
