[Defining the Role of Radiotherapy in Meningioma Treatment].

ABSTRACT

The debate regarding the role and clinical impact of radiotherapy for meningiomas remains underdeveloped due to insufficient evidence. However, following recent revisions in the WHO classification and the integration of molecular diagnostics, there has been a substantial shift in the stratification of recurrence risks. Nevertheless, the specific circumstances under which radiotherapy proves crucial remain unclear. As risk stratification becomes more refined, the effectiveness of radiotherapy in treating high-risk meningiomas continues to be a contentious issue. Concurrently, there is vigorous discussion regarding the management of 'brain invasion in otherwise benign'(BIOB)meningiomas. The incorporation of PET imaging alongside MRI for defining radiation targets is increasingly acknowledged as advantageous. Boron neutron capture therapy(BNCT), which specifically targets the biological characteristics of tumor cells in invasive regions, is also gaining significant traction as a promising therapeutic approach for meningiomas with infiltrative components.
