Background:

Medulloblastoma is the most common pediatric posterior fossa primitive neuroectodermal tumor.
Current treatment involves surgery and craniospinal irradiation, achieving a 75% survival rate.
Research aims to improve prognostic stratification and minimize treatment-related sequelae.

Purpose of the Study:

To review advancements in medulloblastoma treatment strategies.
To highlight the role of molecular markers in risk-adapted therapy.
To discuss methods for reducing long-term side effects.

Main Methods:

Analysis of clinical, histological, and biological markers for risk stratification.
Review of clinical trials evaluating reduced irradiation and novel surgical approaches.

Examination of advanced radiotherapy techniques like intensity-modulated radiotherapy and proton beam therapy.

Main Results:

Molecular markers (Sonic Hedgehog, WNT pathway activation) identify distinct prognostic groups.
Irradiation may be avoidable in some young children with specific tumor types.
Reduced craniospinal irradiation is safe for standard-risk tumors in older children.
New surgical techniques and advanced radiotherapy show promise in reducing long-term sequelae.

Conclusions:

Histological and biological features stratify medulloblastoma patients into prognostic groups.
Current trials focus on maintaining good outcomes while decreasing long-term side effects.
Personalized treatment strategies are emerging based on tumor characteristics.
