Exploring the metastatic potential of isolated tumour cells and clusters-cords patterns of ISUP Grade 5 acinar adenocarcinoma of the prostate: a comprehensive morphological analysis.

Gleason pattern 5 (GP5) prostatic adenocarcinoma (PC) includes distinct morphologies: undifferentiated solid pattern (US), solid and cribriform with necrosis (CN), clusters and cords (CC), and isolated single tumour cells (ISTC). The role of these patterns in the metastatic setting is still poorly understood. We conducted a case-control retrospective histological characterization of two cohorts of ISUP Grade Group 5 PC, one with nodal metastases (N1) and one without (N0), comparing GP5 sub-patterns distribution, from robot-assisted radical prostatectomies with extended lymphadenectomy diagnosed between January 2013 and February 2023.

Pediatric Hemispheric High-Grade Gliomas and H3.3-G34 Mutation: A Review of the Literature on Biological Features and New Therapeutic Strategies.

Pediatric high-grade glioma (pHGG) encompasses a wide range of gliomas with different genomic, epigenomic, and transcriptomic features. Almost 50% of pHGGs present a mutation in genes coding for histone 3, including the subtype harboring the H3.3-G34 mutation.

The Use of Technology-Based Simulation among Medical Students as a Global Innovative Solution for Training.

Background: Technological advancements have been rapidly integrated within the neurosurgical education track since it is a high-risk specialty with little margin for error. Indeed, simulation and virtual reality during training can improve surgical performance and technical skills. Our study aims to investigate the impact of neurosurgical technology-based simulation activities on medical students.

Intrinsic and Microenvironmental Drivers of Glioblastoma Invasion.

Gliomas are diffusely infiltrating brain tumors whose prognosis is strongly influenced by their extent of invasion into the surrounding brain tissue. While lower-grade gliomas present more circumscribed borders, high-grade gliomas are aggressive tumors with widespread brain infiltration and dissemination. Glioblastoma (GBM) is known for its high invasiveness and association with poor prognosis.
