Turcot syndrome

Last edited: 4/16/2026

Overview

Turcot syndrome is a rare hereditary disorder characterized by the association of colonic polyposis with primary central nervous system (CNS) tumors, typically gliomas or medulloblastomas 1. It is classified into two main groups based on genetic mutations: adenomatous polyposis coli (APC) and hereditary non-polyposis colorectal cancer (HNPCC) 1.

Diagnosis

  • Clinical Presentation: Presence of colonic polyposis and CNS tumors, often medulloblastoma in pediatric patients 1.
  • Genetic Testing: Identification of APC gene mutations or mismatch repair gene mutations to differentiate between APC and HNPCC groups 1.
  • Imaging: MRI or CT scans for CNS tumors; colonoscopy for colonic polyposis 1.
  • Histopathology: Biopsy confirmation of polyp histology and tumor pathology 1.

    • Management

  • CNS Tumors: Surgical resection when feasible, followed by radiation therapy and chemotherapy (specific drugs not detailed in the abstract) 1.
  • Colonic Polyposis: Surveillance colonoscopy with polypectomy; colectomy may be indicated for advanced polyposis 1.
  • Supportive Care: Multidisciplinary approach including neurology, oncology, and gastroenterology 1.

    • Special Populations

  • Pediatrics: Early detection and management of medulloblastoma crucial; long survival possible with appropriate treatment 1.
  • Comorbidities: Management tailored to individual tumor types and genetic subtype, with consideration for potential complications from both CNS and gastrointestinal manifestations 1.

    • Key Recommendations

  • Perform genetic testing to classify Turcot syndrome into APC or HNPCC groups for tailored management strategies (Evidence: Moderate 1).
  • Implement aggressive surveillance and intervention for both CNS tumors and colonic polyposis to improve survival outcomes (Evidence: Moderate 1).
  • Consider multidisciplinary care involving neurology, oncology, and gastroenterology to address the complex needs of patients with Turcot syndrome (Evidence: Expert opinion 1).
