This study investigateted the malignant transformation of endometriosis (EMS) into ovarian clear cell carcinoma (OCCC) using spatial transcriptomics and single-cell RNA sequencing (scRNA-seq) integration. Tissues with coexisting EMS and OCC…

Intramural pregnancy (IMP) is an extremely rare form of ectopic pregnancy (EP), typically associated with previous uterine trauma, adenomyosis, or assisted reproductive technology (ART), such as embryo transfer (ET). Despite its potentially…

BackgroundThis study assesses the feasibility of minimally invasive surgery (MIS) for well-selected epithelial ovarian cancer (EOC) patients.MethodsWe performed a review of data prospectively collected from a single center from 2017 to 2022…

Endometriosis is a common benign gynecological disorder; however, delivery outcomes concerning pregnancies with endometriosis remain understudied. This study aimed to assess the effect of endometriosis on delivery outcomes, including the ra…

This study aimed to assess the relationship between placenta accreta spectrum disorder (PASD) and endometriosis. The relationships among pregnancy, assisted reproductive technology (ART), placenta previa, ART-conceived pregnancy and PASD we…

Endometriosis is a common gynecological disease characterized by chronic inflammation, with an estimated prevalence of approximately 5–15% in reproductive-aged women. This study aimed to assess the relationship between placenta previa (PP) …

BackgroundA diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta …

ObjectiveThis study aimed to review the effect of endometriosis on the prevalence of placenta previa and postpartum hemorrhage in pregnant patients and the surgical outcomes of pregnant patients with endometriosis developing placenta previa…

We performed genome-wide association studies of five gynecologic diseases using data of 46,837 subjects (5236 uterine fibroid, 645 endometriosis, 647 ovarian cancer (OC), 909 uterine endometrial cancer (UEC), and 538 uterine cervical cancer…

: We aimed to identify a magnetic resonance imaging (MRI) feature that can predict posterior extrauterine adhesion (posterior adhesion) antenatally, in patients with placenta previa. We retrospectively reviewed patients with placenta previa…

ObjectiveTo examine the association between ovarian conservation and oncologic outcome in surgically-treated young women with early-stage, low-grade endometrial cancer.MethodsThis multicenter retrospective study examined women aged <50 with…

The incidence of cesarean section (c-section) has increased worldwide. Because the major risk factor for uterine scar dehiscence (USD) is a previous c-section, the rate of this complication has also increased. Its clinical significance and …

Advances in surgical and medical treatments for ovarian cancer have improved prognoses. Platinum drugs in particular are pivotal for the medical treatment of ovarian cancer. However, previous studies have revealed that some histological sub…

BackgroundEndometrial cancer arising in adenomyosis (EC-AIA) is a rare entity of endometrial cancer, and its clinical significance has not been well studied. This study aimed to examine the tumor characteristics and survival outcomes of EC-…

Clear cell adenocarcinoma (CCC) is generally thought to originate from ovarian, endometrial, or renal tissue. A CCC of the peritoneum (CCAP) is an extremely rare medical condition and is associated with a poor prognosis. To date, only 10 ca…

Ovarian cancer is the most lethal gynecologic malignancy. It appears that the vast majority of what seem to be primary epithelial ovarian and primary peritoneal carcinomas is, in fact, secondary from the fimbria, the most distal part of the…

Ovarian, endometrial, and cervical cancers are three of the most common malignancies of the female reproductive organs. CA 125, historically the most reliable serum marker for ovarian cancer, is elevated in 50% of early-stage ovarian tumors…

ObjectiveTo clarify the frequency of pregnancy complicated by ovarian endometriosis and to investigate the size change and outcome of ovarian endometriosis during pregnancy.DesignRetrospective study.SettingDepartments of obstetrics and gyne…
