Ultrasound and magnetic resonance imaging are useful tools for the preoperative diagnosis of peritoneal pregnancy; however, accurate diagnosis before surgery remains challenging. We report a rare case of primary peritoneal pregnancy in whic…

To explore the clinicopathological features and origin of mesonephric-like adenocarcinomas (MLAs), 83 cases diagnosed or suspected to be MLAs were collected from various institutions in Japan. We clearly classified 78 as MLAs (uterus: 47, o…

BackgroundAbdominal compartment syndrome (ACS) is a known complication of severe acute pancreatitis. It is typically secondary to visceral edema and aggressive fluid resuscitation, but rarely caused by a retroperitoneal hematoma due to rupt…

BackgroundPatients with chronic pancreatitis (CP) often have severe and intractable abdominal pain, leading to decreased quality of life (QOL), inability to work or attend school, and increased health care costs due to repeated emergency ro…

•A case of concurrent primary ovarian clear cell adenocarcinoma and liver angiosarcoma is detailed herein.•If a liver tumor is found together with ovarian cancer, it is necessary to determine whether this is a primary hepatic malignancy or …

This study examines the association between abnormal cervical cytology and subjective health in pregnant women, as an adjunct to the Japan Environment and Children's Study, which cross-sectionally analyzed a subset of the prospective cohort…

Intra-abdominal bleeding due to uterine fibroids is extremely rare, and preoperative diagnosis is difficult. Herein, we report a case of preoperatively diagnosed hypovolaemic shock due to intra-abdominal haemorrhage, in which fatal sequelae…

In the gynecological literature, a limited number of studies have reported intraperitoneal bleeding due to abdominal blunt trauma. In this report, we describe a rare case of massive intraabdominal hemorrhage from the uterine artery triggere…

The overwhelming majority of participants in current genetic studies are of European ancestry. To elucidate disease biology in the East Asian population, we conducted a genome-wide association study (GWAS) with 212,453 Japanese individuals …

BackgroundEndometrial mesonephric-like adenocarcinomas exhibit classical histologic features of mesonephric carcinoma; however, it remains unclear whether these tumors represent mesonephric (Wolffian) carcinoma or endometrioid (Müllerian) c…

The cancer stroma serves an important role in tumour behaviours, including invasion, metastasis, and response to chemotherapy. The stroma of ovarian carcinoma is sometimes specialized, with luteinisation and/or hyperthecosis, and is designa…

An 84-year-old Japanese woman with myelodysplastic syndrome was admitted with pyrexia and dyspnea, but died suddenly during diagnostic evaluation. The autopsy revealed miliary tuberculosis in addition to myelodysplastic syndrome in the bone…

INTRODUCTION: Although adenomyosis is a common disease, it is a relatively rare site for cancer origin. On the other hand, chocolate cysts have the potential to develop into cancer. We report a case of endometrioid adenocarcinoma occurred a…

Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor and its expression is influenced by environmental compounds, such as 3-methylcholanthrene (3-MC) and β-naphthoflavone (β-NF). AhR and its downstream genes, such as C…

PurposeThe change of mitochondrial distribution in human oocytes during meiotic maturation was assessed using 223 human oocytes donated from patients undergoing fertility treatment between June 2013 and February 2016.MethodsLive cell images…

PurposeThe aim of this study was to determine the prophylactic effects of cabergoline on ovarian hyperstimulation syndrome (OHSS) after oocyte retrieval.MethodsA total of 187 women underwent controlled ovarian stimulation using gonadotropin…

This study examines the role of vascular endothelial growth factor (VEGF) as a therapeutic target in clear cell carcinoma (CCC) of the ovary, which has been regarded as a chemoresistant histologic subtype. Immunohistochemical analysis using…

In this study clinical studies were conducted on galactosyltransferase associated with tumour (GAT) as a newly developed marker of ovarian cancers. The positive rates of GAT with a cut-off value of 16 U/ml (which corresponds to the mean + 2…

We examined GAT, a newly developed tumor marker, in serum samples collected from 1,503 females in six institutions: 387 healthy females, 1,052 patients with gynecological diseases including 311 ovarian cancers, and 64 with nongynecological …

Serum samples from patients with benign or malignant diseases were measured for the newly developed tumor markers CA54/61 and CA602 with the respective EIA kits for assessment of their utility as tumor markers. A total of 5236 patients were…

UNLABELLED: CA125 has been regarded as a marker for hyperplastic conditions, such as endometriosis or infectious peritonitis. A high serum CA125 level should therefore be carefully evaluated clinically. We measured CA125 levels in sera and …

Galactosyltransferase Associated with Tumor (GAT) was clinically studied in cases of ovarian cancer. When two cut-off levels of GAT were compared, the cut-off level of 16 U/ml (which corresponds to mean + 2SD among healthy females) was foun…
