OBJECTIVE:: The purpose of this study is to compare contrast-enhanced ultrasound (CEUS) to MRI for evaluating local invasion of cervical cancer. METHODS:: A total of 108 patients with cervical cancer were included in this study. All the en…

Endometrial cancer is the most commonly diagnosed cancer of the female reproductive tract in developed countries. Through genome-wide association studies (GWAS), we have previously identified eight risk loci for endometrial cancer. Here, we…

BACKGROUND: The Mullerian ducts are the embryological precursors of the female reproductive tract, including the uterus; anti-Mullerian hormone (AMH) has a key role in the regulation of foetal sexual differentiation. Anti-Mullerian hormone …

IMPORTANCE: The causal direction and magnitude of the association between telomere length and incidence of cancer and non-neoplastic diseases is uncertain owing to the susceptibility of observational studies to confounding and reverse causa…

The aim of the study is to describe the clinical characteristics and prognosis of malignant transformation of adenomyosis in patients with endometrial cancer.In this retrospective descriptive study, the clinical data of patients with endome…

BACKGROUND: Regulatory T (Treg) cells, a subset of CD4+ T lymphocytes, are mediators of immunosuppression in cancer, and, thus, variants in genes encoding Treg cell immune molecules could be associated with ovarian cancer. METHODS: In a po…

OBJECTIVE: Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3' UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as wit…

Disruption in circadian gene expression, whether due to genetic variation or environmental factors (e.g., light at night, shiftwork), is associated with increased incidence of breast, prostate, gastrointestinal and hematologic cancers and g…

The aim of the present study was to examine whether the expression of focal adhesion kinase (FAK) is altered in the eutopic endometrium of female patients with adenomyosis, as compared with that of females without adenomyosis. The expressio…

Common variants in the hepatocyte nuclear factor 1 homeobox B (HNF1B) gene are associated with the risk of Type II diabetes and multiple cancers. Evidence to date indicates that cancer risk may be mediated via genetic or epigenetic effects …

Evidence on the association between vitamin D status and pancreatic cancer risk is inconsistent. This inconsistency may be partially attributable to variation in vitamin D regulating genes. We selected 11 vitamin D-related genes (GC, DHCR7,…

OBJECTIVES: This work aims to detect the peritoneal fluid proteomic patterns in endometriosis patients, build diagnostic models, and evaluate its clinical significance. STUDY DESIGN: The authors used SELDI-TOF-MS protein chip array technol…

HNF1B is overexpressed in clear cell epithelial ovarian cancer, and we observed epigenetic silencing in serous epithelial ovarian cancer, leading us to hypothesize that variation in this gene differentially associates with epithelial ovaria…

BACKGROUND: Experimental and epidemiologic evidence have suggested that chronic inflammation may play a critical role in endometrial carcinogenesis. METHODS: To investigate this hypothesis, a two-stage study was carried out to evaluate sin…

BACKGROUND: In addition to mediating aspects of physiologic and pathologic angiogenesis, the VEGF family also contributes to carcinogenesis. METHODS: We comprehensively characterized genetic variation across four VEGF family genes and eval…

OBJECTIVES: To detect specific mitochondrial proteins in eutopic endometrial samples from women with and without endometriosis and to build diagnostic models. DESIGN: Eutopic endometrial samples from women with endometriosis (excluding ade…

Adenomyosis and endometriosis have a similar pathogenesis; indeed, adenomyosis has been considered by some as a variant of endometriosis ('internal endometriosis'). This study aimed to detect differences in mitochondrial proteins in eutopic…

OBJECTIVE: Our study is to investigate whether tyrosine kinase receptor B (TrkB) is expressed in eutopic endometrium of women with adenomyosis and its association with clinical characteristics. METHODS: We collected endometrial tissues fro…

Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) protein chip array technology was used to detect biomarkers of eutopic endometrium in endometriosis patients. Five potential biomarkers (6,898 m/z,…

BACKGROUND: Single nucleotide polymorphisms (SNPs) in the progesterone receptor (PGR) gene have been associated with the risk of endometrial cancer. However, to the authors' knowledge, no study to date has systematically evaluated the role …

PURPOSE: Researchers have launched a new area of febrile investigations on the autophagy-related gene Beclin 1. Our aim is to investigate whether Beclin 1 expression is altered in eutopic endometrium of women with adenomyosis and its associ…

The matrix metalloproteinases (MMP) function as regulators of the dynamic tissue remodeling that occurs in the endometrial lining of the uterus during the normal human menstrual cycle; dysregulation of the MMPs is thought to contribute to t…

OBJECTIVE: To investigate whether focal adhesion kinase (FAK) expression is altered in eutopic endometrium of women with endometriosis. DESIGN: Experimental study using human endometrial tissue. SETTING: Academic research center. PATIENT…

OBJECTIVE: To investigate whether focal adhesion kinase (FAK) is expressed in endometriotic ovarian tissue. METHODS: We collected tissue samples from the ovaries of 41 women with ovarian endometriosis and from the endometrium of 20 healthy…

OBJECTIVES: To use surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) protein chip array technology to detect proteomic patterns in the serum of women with endometriosis; build diagnostic models; an…
