The eutopic endometrium in women with endometriosis demonstrates diminished endometrial receptivity and altered gene expression. It is unknown if the being defective gives rise to a predisposition toward infertility or, alternatively, causes receptivity. Here we created experimental mice examined expression of several markers endometrium. Methylation Hoxa10 was also evaluated as potential mechanism responsible for Expression each measured using quantitative real-time RT-PCR at 14 wk after...

The aim of this study was to evaluate circulating tumor cell (CTC) detection in the differential diagnosis adnexal masses. A total 87 preoperative women with an indeterminate mass were prospectively enrolled. Preoperative diagnostic modalities including CTC detection, risk ovarian malignancy algorithm, index, and computed tomography or magnetic resonance imaging compared. Forty-three (49.4%) benign tumors, 13 (14.9%) borderline malignant masses, 31 (35.7%) cancers pathologically confirmed....

Outcomes of patients with ovarian high-grade serous carcinoma (HGSC) treated neoadjuvant chemotherapy (NAC) have been widely studied, but there is limited information on the outcomes non-HGSC. This study aimed to evaluate NAC in non-HGSC advanced-stage cancer. We conducted a retrospective cohort who underwent for advanced stage between 2002 and 2017 17 institutions. Demographics, surgical outcomes, survival rates were evaluated according histological subtypes. A total 154 included this...
