Precision Neurosurgery in the Era of Molecular Neuro-Oncology: Redefining the Role of Surgical Intervention in Intracranial Tumors

Introduction: The integration of molecular markers into neuro-oncology has reshaped the role of surgery in intracranial tumors. Precision neurosurgery combines advanced imaging, intraoperative mapping, and molecular profiling to optimize resection while preserving neurological function.

Methodology: A literature review of peer-reviewed studies from 2000 to 2025 was conducted using PubMed and Scopus databases. Search terms included “precision neurosurgery,” “molecular neuro-oncology,” and “intracranial tumors.” Studies addressing the impact of molecular markers on surgical strategy and patient outcomes were included.

Results: Evidence highlights that IDH mutations, 1p/19q co-deletion, and MGMT promoter methylation strongly influence surgical decision-making and prognosis. Precision approaches allow surgeons to tailor interventions to the molecular biology of each tumor, improving both survival and functional outcomes.

Conclusion: Precision neurosurgery, integrated with molecular neuro-oncology, is redefining surgical goals and strategies. It represents a critical evolution in brain tumor management, offering personalized and outcome-driven care.
