Lynch syndrome is a hereditary ovarian cancer with a prevalence of 0.9-2.7%. Lynch syndrome accounts for 10-15% of hereditary ovarian cancers, while hereditary breast and ovarian cancer syndrome accounts for 65-75% of these cancers. The lif…
The medical liquid crystal display (LCD) monitor is a conventionally used imaging device for diagnosis and during endoscopic surgery. Recently, a medical organic electroluminescence panel, the organic light-emitting diode (OLED) monitor, wa…
OBJECTIVE: Previous studies have reported an association between endometrial cancer and the risk of metabolic syndrome; however, the pattern of endometrial cancer-associated dyslipidemia is not well understood. The standard therapy for endo…
Cases of endometrial cancer have increased in recent years, but the prognosis of patients with this disease has also been improved by combined modality therapy with surgery, radiotherapy and chemotherapy. However, the development of new the…
OBJECTIVE: Uterine transplantation experiments have been performed in various animal species for future clinical applications of uterine transplantation for permanent uterine factor infertility in humans. The aim of this study was to confir…
Progestin preparations are made of synthetic progesterone and have often been used for hormone therapy in gynecological patients with endometriosis or endometrial cancer. Hormone therapy using progestin is considered to be one of the effect…
Numerous studies have suggested that the different histological subtypes of ovarian carcinoma (i.e. clear cell, endometrioid, mucinous, and serous) have distinct clinical histories and characteristics; however, most studies that have aimed …
PURPOSE: Ovarian clear cell adenocarcinoma (OCCA) has been reported to display different characteristics from other histological types of epithelial ovarian cancer, and especially differs from serous adenocarcinoma. We investigated plasmino…
Narrow band imaging (NBI) is a new endoscopic technique in which images of mucosal microstructures and capillary structures are enhanced by shifting the light spectrum to a narrow band. Image-enhanced gastrointestinal endoscopy using NBI ha…
Although the pathogenesis of endometriosis is not well understood, genetic factors have been considered to have critical roles in its etiology. Through a genome-wide association study and a replication study using a total of 1,907 Japanese …
We present a case of a 19 year-old woman with endometriosis treated by laparoscopy 6 years after a liver transplant. This case had a high risk of visceral injury during trocar insertion. We used cine MRI for evaluation of intra-abdominal ad…
OBJECTIVE: To investigate the factors related to activation of transforming growth factor-beta 1 (TGF-beta1) at sites of endometriosis. STUDY DESIGN: TGF-beta1 is activated by plasmin, which is formed when plasminogen is activated by uroki…
OBJECTIVE: To investigate differences in the biological characteristics of ovarian clear cell adenocarcinoma based on the presence/absence of endometriosis and tumor proliferative activity. METHODS: Stage I ovarian clear cell adenocarcinom…
A new efficient screening for ovarian cancer based on a combination of two tumor markers, CA602 and CA546, is reported. These two tumor markers can be detected by a combination immunoenzymometric assay of these two antigens. This combinatio…
BACKGROUND: To investigate the incidence of pulmonary embolism and risk factors for this condition after obstetric and gynecologic surgery, as well as the efficacy of intermittent pneumatic compression. METHODS: A total of 6,218 patients o…
OBJECTIVE: Ovarian clear cell carcinoma is commonly associated with pelvic endometriosis. We retrospectively evaluated clinicopathological data on the association between ovarian clear cell carcinoma and pelvic endometriosis. METHODS: Betw…
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…
Dienogest is an orally active synthetic steroid that is used for contraception and is currently being studied for the possible treatment of endometriosis. Earlier we demonstrated that dienogest had therapeutic effects on experimental endome…
BACKGROUND: Dienogest is a synthetic progestational steroid that is used for contraception. It is being studied for the treatment of endometriosis, but its anticancer activity remains unknown. The authors investigated the anticancer effect …
