We present the third case of subarachnoid haemorrhage (SAH) during dienogest (DNG) therapy documented in Japan. A woman in her 40s with a history of smoking and a family history of SAH developed a sudden severe headache and was diagnosed wi…

Familial Mediterranean fever (FMF) is an inherited autoinflammatory disease characterized by recurrent bouts of fever and serositis. Mediterranean Fever (MEFV) gene mutations may cause not just FMF but various serositis including arthritis,…

A few cases of spontaneous parasitic myoma have been reported. However, its cause remains unidentified. We report a case of spontaneous parasitic pedunculated subserosal myoma with pathological findings presenting with the absence of uterin…

IntroductionWe have reported previously that fecal DNA testing of TWIST1 methylation in combination with the fecal immunochemical test for hemoglobin (FIT) (combination test) is useful for colorectal neoplasia screening. In this study, usin…

BackgroundSelf-expandable metallic stenting (SEMS) for malignant colorectal obstruction (MCO) as a bridge to elective surgery (BTS) is a widely used procedure. The aim of this study was to assess short-term outcomes of SEMS for MCO as BTS.M…

OBJECTIVE: Although CA125 antigen is a useful marker for ovarian cancer, its expression is also elevated in endometriosis. The purpose of this study was to develop an assay method for evaluating differentially glycosylated MUC16 (CA125 core…

Two histologic types, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC), are the common histology in ovarian cancer patients who have associated endometriosis. However, both tumor types have distinct clinicopathological chara…

Inflammation plays a role in the pathogenesis of endometriosis. Endometriosis-associated ovarian carcinogenesis might be promoted through oxidative stress-induced increased genomic instability, aberrant methylation, and aberrant chromatin r…

This review summarizes data from recent molecular genetic and epidemiology studies of the generic term 'female pelvic cancer'. The English-language literature was reviewed for genetic, epigenetic, epidemiologic and environmental risk factor…

ObjectiveEpithelial ovarian cancer (EOC) is the most lethal pelvic gynecologic cancer. Clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) of the ovary have been associated with endometriosis, thus indicating that endometriosis…

Recent data have provided information regarding the profiles of clear cell carcinoma of the ovary (CCC) with adenine-thymine rich interactive domain 1A (ARID1A) mutations. The purpose of this review was to summarize current knowledge regard…

Epithelial ovarian cancer (EOC) is the most common cause of gynecological cancer-related mortality. Clear cell EOC (cEOC) has a number of clinical features distinguishing it from other EOC because of frequent concurrence of endometriosis an…

In the ovary, clear cell carcinoma (CCC) and endometrioid adenocarcinoma occur in the setting of endometriosis. In this review, we discuss the role of innate immune responses, specifically endogenous ligands (also known as "alarmins"), thei…

BACKGROUND: Various theories try to explain the development and progression of endometriosis, however, no single theory can explain all aspects of this disorder. Gene expression profiling studies might reveal factors that explain variabilit…

Endometriosis affects an estimated 10% of women in the reproductive-age group. Here, we review current knowledge on molecular genesis of endometriosis-associated epithelial ovarian carcinoma (EOC). This article reviews the English language …

Epithelial ovarian cancer (EOC) is the leading cause of death in women with gynecological malignancies. Among EOC, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) differ from the other histological types with respect to the…

PROBLEM: Clear cell carcinoma (CCC) of the ovary has a number of features distinguishing it from other epithelial ovarian carcinomas (EOC) because of its characteristic histology and biology, frequent concurrence with endometriotic lesion, …

BACKGROUND: Endometriosis may cause symptoms including chronic pelvic pain and infertility, and increases susceptibility to the development of ovarian cancer. Genomic studies have started to delineate the wide array of mediators involved in…

ObjectiveOur prospective studies in Japan have found an increased ovarian cancer incidence in women with ovarian endometrioma (standardized incidence ratio, 8.95; 95% confidence intervals, 4.12-5.3). The risk increased with increasing age a…

The detection of an ovarian mass during pregnancy is often a diagnostic challenge. We describe 2 cases of ovarian endometrioma during pregnancy with marked mural nodules on the cyst wall. The sonographic and MR imaging findings mimicked ova…

OBJECTIVE: We investigated a possible association between endometriosis and polymorphisms in the genes encoding epidermal growth factor (EGF) receptor (EGFR) and EGF in a Japanese population. METHODS: We compared the distribution of the Eg…

BACKGROUND: Vascular endothelial growth factor (VEGF) concentration in endometriosis patients is higher than controls, in serum and ascites, suggesting that VEGF may play an important role in the pathogenesis of endometriosis. In this study…

ObjectiveEndometriosis is an immune-related, chronic inflammatory disease with polygenic predisposition. Cell adhesion molecules are expressed in endometriotic lesions, and in cells and tissues that are involved in the development and progr…

ObjectiveWe investigated the association between endometriosis and polymorphisms in the N-acetyltransferase 1 (NAT1) and N-acetyltransferase 2 (NAT2) genes in a Japanese population, having previously demonstrated a positive association with…
