AI Article Synopsis

  • Rhabdoid tumor is a rare and aggressive cancer mainly found in infants and young kids, typically appearing in the brain and kidneys, but can also occur in other soft tissues.
  • SMARCB1 acts as a tumor suppressor and is often mutated or deleted in these tumors, linking it to a higher risk of rhabdoid tumors and the genetic disorder schwannomatosis.
  • Current research suggests these tumors are primarily driven by epigenetic changes rather than specific biological pathway alterations, leading to the exploration of new treatment strategies based on this understanding.

Article Abstract

Rhabdoid tumor is a rare, highly aggressive malignancy that primarily affects infants and young children. These tumors typically arise in the brain and kidney, although extrarenal, non-central nervous system tumors in almost all soft-tissue sites have been described. SMARCB1 is a member of the SWI/SNF chromatin-remodeling complex and functions as a tumor suppressor in the vast majority of rhabdoid tumors. Patients with germline mutations or deletions affecting SMARCB1 are predisposed to the development of rhabdoid tumors, as well as the genetic disorder schwannomatosis. The current hypothesis is that rhabdoid tumors are driven by epigenetic dysregulation, as opposed to the alteration of a specific biologic pathway. The strategies for novel therapeutic approaches based on what is currently known about rhabdoid tumor biology are presented.

A case of rhabdoid meningioma originating from the optic nerve.

Neuropathology

January 2025

Department of Pathology, Shenzhen Second People's Hospital, Shenzhen University 1st Affiliated Hospital, Shenzhen, China.

We report a rare case of rhabdoid meningioma (RM) originating from the optic nerve in a 57-year-old female. The tumor exhibited rhabdoid or epithelioid histology and harbored BAP1 inactivation mutations. Optic nerve meningioma typically originates from the outer meningeal cells of the optic nerve within the optic canal and is usually benign, with most cases classified as meningothelial or transitional meningiomas.

Purpose: Atypical teratoid/rhabdoid tumor (AT/RT) is a kind of central nervous system malignant tumor in children. In this study, we aimed to develop a practically clinical nomogram and risk grouping system to predict 1-year overall survival for patients with atypical teratoid/rhabdoid tumor.

Methods: The nomogram was constructed based on the pediatric tumor registry of Xinhua Hospital affiliated to Shanghai Jiaotong University School of Medicine.

Rhabdoid tumours (RT) are an aggressive malignancy affecting <2-year-old infants, characterised by biallelic loss-of-function alterations in SWI/SNF-related BAF chromatin remodelling complex subunit B1 (SMARCB1) in nearly all cases. Germline SMARCB1 alterations are found in ~30% of patients and define the RT Predisposition Syndrome type 1 (RTPS1). Uveal melanoma (UVM), the most common primary intraocular cancer in adults, does not harbour SMARCB1 alterations.

Background: Central nervous system (CNS) tumors lead to cancer-related mortality in children. Genetic ancestry-associated cancer prevalence and outcomes have been studied, but is limited.

Methods: We performed genetic ancestry prediction in 1,452 pediatric patients with paired normal and tumor whole genome sequencing from the Open Pediatric Cancer (OpenPedCan) project to evaluate the influence of reported race and ethnicity and ancestry-based genetic superpopulations on tumor histology, molecular subtype, survival, and treatment.

Background: Atypical teratoid/rhabdoid tumours (ATRTs) are malignant central nervous system tumours, typically presenting in the posterior fossa of very young children. Prognosis remains poor despite current therapy, while tumorigenesis implicates both genomic and epigenetic dysregulation. Primary diffuse leptomeningeal (PDL) ATRT, characterised by the absence of an intraparenchymal mass lesion, is seldom reported but appears associated with a dismal outcome.
