mTOR inhibitor in the treatment of TFE-positive advanced maligmnant PEComa of the uterus: a case report and literature review.

Background: The pre- and intra-operative diagnoses of malignant uterine vascular perivascular epithelioid cell tumors (PEComas) can be challenging, for which the literature is limited. Some cases have been shown to have TSC gene mutations or rearrangements of the MiT factor family, resulting in variable responses to mTOR inhibitors. We report a case of a TFE-positive malignant PEComa of the uterus with pulmonary metastases that responded favorably to the mTOR inhibitor, everolimus.

Comparison of the efficacy and safety of total laparoscopic hysterectomy without and with uterine manipulator combined with pelvic lymphadenectomy for early cervical cancer.

Objective: Some studies have reported that the prognosis of total laparoscopic hysterectomy (TLH) for early-stage cervical cancer (CC) is worse than that of open surgery. And this was associated with the use of uterine manipulator or not. Therefore, this study retrospectively analyzes the efficacy and safety of TLH without uterine manipulator combined with pelvic lymphadenectomy for early-stage CC.

Vaginal microecological changes of different degrees of cervical lesions in Hakka women in Meizhou City.

Research shows an association between vaginal microbiota and the development of cervical cancer, but the role of altered microbiota in cancer development remains controversial. In this study, we attempted to reveal the vaginal microecological changes in cervical lesions by 16S rRNA gene sequencing. Vaginal secretions were collected from Hakka women in Meizhou City, Guangdong Province, China.
