ObjectiveMedroxyprogesterone acetate (MPA) is an effective fertility-preserving treatment for early endometrial cancer and atypical endometrial hyperplasia (AEH), and rarely leads to the development of extrauterine lesions (ELs). We aimed t…

ObjectiveTo optimize prediction for intestinal invasion of epithelial ovarian cancer. It is important to achieve debulking surgery to improve prognosis in ovarian cancer; intestinal resection is adopted if the cancer is invaded and resectab…

BACKGROUND Endometriosis is defined as the growth of ectopic endometrial tissue beyond the uterine cavity, and endometriosis on the uterine cervix is a rare variant. Although asymptomatic patients with cervical endometriosis or those with m…

Pelvic inflammatory disease (PID) sometimes develops after intrauterine insemination (IUI). We herein present a case of PID which developed after IUI performed after abdominal modified radical trachelectomy (AmRT) and was treated with lapar…

The AT-rich interacting domain‑containing protein 1A gene (ARID1A) encodes ARID1A, a member of the SWI/SNF chromatin remodeling complex. Mutation of ARID1A induces changes in expression of multiple genes (CDKN1A, SMAD3, MLH1 and PIK3IP1) vi…

AIM: Micro ribonucleic acids (miRNAs) play an important pathological role in endometriosis. Leuprolide acetate, an analog of gonadotropin-releasing hormone, is widely used to treat endometriosis; however, the molecular mechanisms involved i…

OBJECTIVE: Synchronous primary endometrial and ovarian cancers have been an important topic in clinical medicine because it is sometimes difficult to distinguish whether there are 2 primary tumors or a single primary tumor and an associated…

AIM: Leuprolide acetate, an analog of gonadotropin-releasing hormone (GnRH), regresses endometriotic tissue and reduces pain, resulting in clinical improvement upon treatment. The molecular mechanisms involved in the regression of endometri…

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…

ObjectivePrevious 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 endome…

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…

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…
