Background: Positron emission tomography/computed tomography (PET/CT) fails to detect approximately 25% of aortic lymph node metastasis in patients with PET/CT stage IIIC1 cervical cancer. Surgical staging could lead to treatment modification and to improved para-aortic and distant control.

Primary Objectives: To demonstrate if chemoradiation with tailored external beam radiation field based on surgical staging and pathologic examination of the para-aortic lymph node is associated with improved 3-year disease-free survival compared with patients staged with PET/CT staging only.

(1) Background: A complete tumor resection during primary cytoreductive surgery has been reported to be the most important and perhaps the only independent prognostic factor in advanced ovarian cancers. The goal of complete cytoreduction needs to be weighed against the potential morbidities and long-term survival outcomes. (2) Methods: in this retrospective analysis of a prospectively obtained database, 208 consecutive patients with advanced ovarian cancer who underwent a conventional primary cytoreductive surgery (150 patients) or TROMP technique (58 patients) were included.

(1) Background: Sentinel lymph node staging (SLN) with indocyanine green (ICG) in cervical cancer is the standard of care in most national and international guidelines. However, the vast majority of relevant studies about the safety and feasibility of this method are conducted on minimally invasive surgery; (2) Methods: This study is a retrospective analysis of a retrospective collected database of 76 consecutive patients with cervical cancers, who were operated laparoscopically (50%), or laparotomy (50%). Sentinel nodes were defined as the ICG-positive pelvic nodes in the first and second echelons.

Article Synopsis
  • The study aimed to evaluate treatment options and recurrence patterns for patients with grade 3 endometrioid endometrial cancer (G3-EEC) by analyzing data from 11 gynecological oncology centers over a 22-year period.
  • Among 465 women analyzed, the 5-year disease-free survival (DFS) rate was 50.3%, and the overall survival (OS) rate was 57.6%, highlighting significant outcomes based on surgical success.
  • The findings indicated that inadequate lymphadenectomy negatively impacted survival rates, serving as an independent prognostic factor, while optimal surgery and adequate lymphadenectomy positively correlated with better survival in advanced-stage patients.

The current understanding of radical hysterectomy more is centered on the uterus and little is being discussed about the resection of the vaginal cuff and the paracolpium as an essential part of this procedure. This is because that the current classifications of radical hysterectomy are based only on the lateral extent of resection. This way is easier to be understood but does not reflect the anatomical and surgical conception of radical hysterectomy and the three-dimensional ways of tumour spreading, neither meet the need of adjusting the radicality according to the different stages of FIGO classification, which depends-at least in the early stages-on the tumour volume and the infiltration in the vagina (but not on the directly spread in the parametrium).

Minimally invasive surgery (MIS) has become the standard approach in early stage cervical cancer (ECC). However, the recently published "LACC" trial and even others could show inferior PFS and OS of MIS compared to open radical hysterectomy. The results led to a widespread debate about the best surgical approach in ECC.

Whilst systematic lymph node dissection has been less prevalent in gynaecological cancer cases in the last few years, there is still a good number of cases that mandate a systematic lymph node dissection for diagnostic and therapeutic purposes. In all of these cases, it is crucial to perform the procedure as a nerve-sparing technique with utmost exactitude, which can be achieved optimally only by isolating and sparing all components of the aortic plexus and superior hypogastric plexus. To meet this purpose, it is essential to provide a comprehensive characterization of the specific anatomy of the human female aortic plexus and its variations.

  • - The study aimed to determine if maternal serum levels of VEGF or NT-proBNP can better predict abnormally invasive placenta (AIP) and assess the invasion degree in pregnant women.
  • - Data were collected from 44 women with AIP and 55 with uncomplicated pregnancies, comparing the serum levels right before delivery; results showed lower VEGF and higher NT-proBNP in women with AIP.
  • - Findings indicated that lower VEGF levels are a better predictor of AIP than NT-proBNP, with VEGF also showing an inverse relationship with the severity of invasion (clinical AIP degree).

The current understanding of radical hysterectomy is more centered on the uterus and little is discussed regarding the resection of the vaginal cuff and the paracolpium as an essential part of this procedure. The anatomic dissections of two fresh and 17 formalin-fixed female pelvis cadavers were utilized to understand and decipher the anatomy of the pelvic autonomic nerve system (PANS) and its connections to the surrounding anatomical structures, especially the paracolpium. The study mandates the recognition of the three-dimensional (3D) anatomic template of the parametrium and paracolpium and provides herewith an enhanced scope during a nerve-sparing radical hysterectomy procedure by precise description of the paracolpium and its close anatomical relationships to the components of the PANS.

There is an obvious prevalence of disparity in opinions concerning the technique of nerve-sparing radical hysterectomy and its application, despite agreement on the need to spare the pelvic autonomic nerve system during such a radical operation. Understanding the precise three-dimensional anatomy of paracolpium and its close anatomical relationship to the components of the pelvic autonomic nervous system is the key in performing the nerve-sparing radical hysterectomy. A total of 42 consecutive patients with primary cervical cancers, who were operated upon in our institution between January 2017 and June 2019, were analyzed, concerning surgical, urinary functional, and short-term oncologic outcomes.
