PURPOSE: To characterize early learning curves for two gynecologic oncologists and their first assistants using the Hugo robotic-assisted surgery system for hysterectomy in benign uterine disease or FIGO stage IA endometrial cancer. METHOD…

We aimed to generate immortalized stromal cell lines from the ovarian and fallopian tube tissues of a single patient using Sendai virus (SeV) vectors and identify candidate stromal genes involved in ovarian carcinogenesis. Tissues were coll…

BACKGROUND: This study evaluated the effectiveness of preoperative inflammatory response markers in distinguishing clear cell carcinoma (CCC) and endometrioid carcinoma (EC) from ovarian endometrioma. METHODS: Patients with stage I ovarian…

Conventional therapies for metastatic cancers have limited efficacy. Recently, cancer therapies targeting noncancerous cells in tumor microenvironments have shown improved clinical outcomes in patients. However, further advances in our unde…

BACKGROUND: Endometrial cancer is the most common gynecological malignancy; however, there is no useful blood diagnostic biomarker. This study aimed to determine the utility of tissue factor pathway inhibitor 2 (TFPI2), a biomarker of ovari…

BACKGROUND: Uterine adenosarcoma is a rare malignant tumor that accounts for 8% of all uterine sarcomas, and less than 0.2% of all uterine malignancies. However, it is frequently misdiagnosed in clinical examinations, including pathological…

Malignant pericardial effusion is an uncommon metastatic manifestation of ovarian carcinoma. Few cases of ovarian serous carcinoma have been previously reported. Ovarian clear cell carcinoma is the second most common histologic subtype in E…

AIM: This study aimed to compare introduced robotic-assisted hysterectomy (RAH) and skilled total laparoscopic hysterectomy (TLH) for the treatment of benign gynecological diseases. METHODS: Patients who underwent RAH or TLH by two surgeon…

Uterine adenomyosis is an estrogen-dependent tumor and one of the most common benign diseases in sexually mature women. The frequency of endometrial cancer associated with adenomyosis has been reported to be 18%–66%. On the other hand, endo…

Uterine adenomyosis is an estrogen-dependent tumor and one of the most common benign diseases in sexually mature women. The frequency of endometrial cancer associated with adenomyosis has been reported to be 18%-66%. On the other hand, endo…

PURPOSE: To investigate the role of estrogen receptors (ERs) in high-grade serous carcinoma (HGSC) and clear cell carcinoma (CCC) of the ovary and evaluate ERs as prognostic biomarkers for ovarian cancer. METHODS: This study included 79 pa…

Primary ureteral endometriosis is considered to be an uncommon form with an incidence of less than 0.1% in endometriosis. We reported a case of retroperitoneal endometrioid carcinoma possibly arising from ureteral endometriosis. A 52-year-o…
