Objectives: Long term outcomes following fertility sparing robot-assisted radical trachelectomy (RRT).

Methods: A retrospective study of consecutive women selected for RRT between 2007 and 2019 at five referral centres. Generally used selection criteria for fertility-sparing surgery were applied.

Objectives: Women with a previous trachelectomy have an increased risk of premature delivery and second trimester miscarriage. In this study we aim to evaluate factors and regimes possibly affecting the risk for prematurity following fertility sparing robotic radical trachelectomy (RRT) in cervical cancer.

Methods: A retrospective study of the reproductive outcome following RRT with a cervical cerclage performed at one of four academic centers between 2007 and 2019.

Background: Epithelial ovarian cancer is a common malignancy, with no clinically approved diagnostic biomarker. Engrailed-2 (EN2) is a homeodomain-containing transcription factor, essential during embryological neural development, which is dysregulated in several cancer types. We evaluated the expression of EN2 in Epithelial ovarian cancer, and reviewed its role as a biomarker.

Epithelial ovarian cancer (EOC) is the leading cause of death among gynecological malignancies worldwide. The five-year survival rates for stage IIIC and IV patients are 29% and 13%, respectively. Type-2 EOC cells have been found to be associated with this late stage disease.

The authors previously demonstrated nerve trunks and autonomic ganglia of the hypogastric plexus within the uterosacral ligament (USL) and the cardinal ligaments. The nerve content of these ligaments is greatest closer to the pelvic sidewalls and diminishes toward the insertion of the ligaments into the uterus, with the greater nerve content in the USL. Here the authors determine whether the nerve content of the superficial and deep portion of the USLs, where they are divided at a radical hysterectomy, differ.

Objective: Using neuropeptide and enzyme markers to autonomic nerves, we sought to demonstrate and quantify the nerve types contained within the uterosacral ligaments (USLs) and cardinal ligaments (CLs) that are divided during radical hysterectomy (RH).

Methods: Cross-sectional biopsies were collected from the lateral third of the USL and the CL in 24 women who had an RH for cervical cancer, and from the uterine insertion of these ligaments in 11 women who had a simple hysterectomy for benign disease. We applied indirect immunofluorescence with FITC-conjugated secondary antibodies, using polyclonal primary antibodies to neuropeptide markers that predominate within somatic and autonomic nerves, to show different populations of the following nerve types within the biopsies: neuropeptide Y (NPY) and tyrosine hydroxylase (TH) for sympathetic nerves; vasoactive intestinal polypeptide (VIP) for parasympathetic nerves; substance P (SP) for nociceptive and sensory-motor nerves; and calcitonin gene-related peptide (CGRP) for sensory and sensory-motor nerves.
