Objective: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy.

Methods: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016.

COVID-19 has caused unprecedented societal turmoil, triggering a rapid, still ongoing, transformation of healthcare provision on a global level. In this new landscape, it is highly important to acknowledge the challenges this pandemic poses on the care of the particularly vulnerable cancer patients and the subsequent psychosocial impact on them. We have outlined our clinical experience in managing patients with gastrointestinal, hematological, gynaecological, dermatological, neurological, thyroid, lung and paediatric cancers in the COVID-19 era and have reviewed the emerging literature around barriers to care of oncology patients and how this crisis affects them.

Human Papilloma Virus has been considered as the main cause for cervical cancer. In this study we investigated epigenetic changes and especially methylation of specific sites of HPV genome. The main goal was to correlate methylation status with histological grade as well as to determine its accuracy in predicting the disease severity by establishing optimum methylation cutoffs.

Objectives: To assess outcomes after secondary surgical resection in patients with recurrent uterine leiomyosarcoma (uLMS).

Methods: We retrospectively identified all patients who had no evidence of disease after initial surgery for uLMS, who underwent surgery for a first recurrence at our institution between 1/1991 and 10/2013. We excluded patients who received any therapy for recurrence prior to secondary resection, and patients who underwent surgery soon after morcellation [of presumed benign fibroids] showed widespread disease.

Background: γH2AX is a protein biomarker for double-stranded DNA breakage; its expression was studied in cervical squamous intraepithelial lesions and carcinomas.

Methods: Immunostaining for phospho-γH2AX was performed in sections from histologically confirmed cervical SIL and carcinomas, as well as from normal cervices used as controls. In total, 275 cases were included in the study: 112 low grade SIL (LGSIL), 99 high grade SIL (HGSIL), 24 squamous cell carcinoma (SCC), 12 adenocarcinoma and 28 cervical specimens with no essential lesions.

Background: Pelvic radiotherapy (RT) is a standard component of the management for patients with locally advanced rectal cancer or squamous cell carcinoma of the anus. Pelvic RT leads to permanent and irreversible ovarian failure in young women. This study aimed to determine the effectiveness of robotically assisted laparoscopic ovarian transposition (OT) before RT in women with rectal or anal cancer who wanted to preserve normal ovarian function.

Background: Minimally invasive surgery (MIS) is associated with decreased complication rates, length of hospital stay, and cost compared with laparotomy. Robotic-assisted surgery-a method of laparoscopy-addresses many of the limitations of standard laparoscopic instrumentation, thus leading to increased rates of MIS. We sought to assess the impact of robotics on the rates and costs of surgical approaches in morbidly obese patients with uterine cancer.

We aim to present the first case of a pregnancy achieved by administering sildenafil (Viagra) to a woman not responding to controlled ovarian hyperstimulation (COH) with the sole use of gonadotropins. A 37-year-old woman underwent COH, as part of an intracytoplasmic sperm injection (ICSI) cycle, with the combination of r-FSH and HMG for 13 d, without evidence of follicular growth. The addition of oral sildenafil at a dose of 50 mg per day for a total of five doses improved the ovarian response and resulted in the retrieval of 10 oocytes.

The study was designed to investigate the effect of dexamethasone (DEX) on the latency period to delivery in a murine model of preterm labor. To this purpose, pregnant mice were randomly assigned in groups: the control group received water for injection (n=20), the preterm labor group was injected with lipopolysaccharide (LPS) (n=22), while the glucocorticoids group was administered DEX either 1h before (n=17) or after (n=7) lipopolysaccharide. In a first set of experiments animals were monitored to record perinatal outcomes.

Objective: Recently, it has been debated whether the new polycystic ovary syndrome (PCOS) phenotypes, according to the Rotterdam criteria, share the same metabolic risk with the classic ones (National Institutes of Health 1990). Our study sought to compare the prevalence of metabolic syndrome (MS) and glucose homeostasis disorders in Greek women with classic and new PCOS phenotypes.

Materials And Methods: Two hundred and sixty-six Greek PCOS women were recruited and divided into groups according to two of the three Rotterdam criteria that they fulfilled.

Aim: Epithelial cadherin (E-cadherin), a transmembrane glycoprotein involved in calcium-dependent homophilic cell-cell adhesion, is expressed aberrantly during cervical carcinogenesis. E-cadherin expression and putatively implicated predictors in healthy women remain a rather under-investigated area. The objective of this study is to evaluate the possible associations between E-cadherin expression and reproductive/lifestyle factors in cervical epithelial cells from postmenopausal women.
