Recent studies demonstrated that protease-activated receptor-2 (PAR-2) correlates with tumor progression in various tissues. On the other hand, oxidative stress arising from endometriosis has been considered a cause of carcinogenesis in ova…

The clinical significance of coexistence of endometriosis (EM) in ovarian clear cell carcinoma (CCC) has not yet been determined. The aim of the present study was to analyze the correlation of endometriosis with clinicopathological factors …

BackgroundTo achieve optimal cytoreduction for advanced-stage ovarian cancer, modified posterior exenteration is the most frequently performed bowel surgery. We assessed the extents of tumor spreading in the rectosigmoid wall and pelvic sid…

'Polypoid endometriosis' is a rare variant of endometriosis. We describe a case of an extremely large polypoid endometriosis mimicking a malignant tumor. A 37-year-old nulliparous woman was referred due to the rapid growth of an endometriot…

BHLHE40 and BHLHE41 (BHLHE40/41) are basic helix-loop-helix type transcription factors that play key roles in multiple cell behaviors. BHLHE40/41 were recently shown to be involved in an epithelial-to-mesenchymal transition (EMT). However, …

We report the case of 23 year-old woman with OHVIRA syndrome (obstructed hemivagina and ipisilateral renal anomaly) discovered during management for right renal failure. Non-specific symptoms such as lower abdominal pain, dysmenorrhea, and …

PurposeWe retrospectively examined a large cohort of females who underwent single blastocyst transfer to determine if initial β-human chorionic gonadotrophin (β-hCG) levels on day 7 after single vitrified-warmed blastocyst transfer (SVBT) c…

Müllerian mucinous borderline tumors (MMBTs) usually arise from the ovary. The present report is the first case of primary uterine MMBTs associated with adenomyosis. A 51-year-old woman was referred to our hospital for a complex cystic and …

Recently, adult stem cells have been identified in several mature tissues. The human endometrium is responsive to sex steroid hormone. It undergoes extraordinary growth in a cyclic manner and is shed and regenerated throughout a woman's lif…

Primary squamous cell carcinoma (SCC) associated with ovarian endometriosis is extremely rare and has a poor prognosis due to insufficient information on the optimal postoperative treatment. Here, we describe the response of this tumor to t…

Gene expression profiling can be of benefit in identifying critical factors in the process of disease initiation and development. However, in endometriosis it has proven difficult to identify common genes between DNA microarray studies, pre…

Cancer stem-like cell subpopulations, referred to as "side-population" (SP) cells, have been identified in several tumors based on their ability to efflux the fluorescent dye Hoechst 33342. Although SP cells have been identified in the norm…

The treatment for severe adenomyosis has usually been hysterectomy, because there is no line of demarcation between diseased and normal tissue. Yet many such women wish to retain their uterus and some even wish to bear children. This report…

ObjectiveA computer based, temperature controlled bipolar coagulation system has been developed.Study designEndometriosis was induced in 39 mature female rats by means of transplantation of endometrium on the peritoneal wall near the ovary.…

ObjectiveIn our previous study, 119 patients with histologically confirmed endometriosis underwent a 'three-step' therapy between 1987 and 1989, where surgical removal of endometriosis was followed by a 6 month treatment with 3 x 300 microg…

Endometriosis was induced in 40 mature female rats by means of transplantation of endometrium on the peritoneum near the ovary. Three weeks later, all the rats were laparotomized and they were randomized into four groups according to treatm…

To differentiate between ovarian carcinoma and benign ovarian tumor, we compared alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LDH) and its isoenzyme activities in serum in 115 patients with ovarian carcinoma and benign …
