Neuroimaging and genetic influence in treating brain neoplasms

Area of Science:

• Neuroimaging
• Oncology
• Genetics

Background:

• Current glioblastoma (GBM) treatments (surgery, radiation, chemotherapy) offer limited survival benefits.
• Personalized medicine is crucial for enhancing patient management and overall survival in GBM.
• Genetic characterization of high-grade gliomas is a key goal in neuroimaging.

Purpose of the Study:

• To review genetic alterations in high-grade gliomas.
• To explore the implications of these genetic alterations for patient treatment and prognosis.
• To correlate MR imaging features with genetic aspects of GBMs.

Main Methods:

• Review of current literature on glioblastoma genetics and neuroimaging.
• Correlation of MR imaging findings with known genetic alterations in gliomas.
• Analysis of post-treatment phenomena (pseudoprogression, pseudoresponse) in relation to genetic expression.

Main Results:

• Specific genetic alterations in high-grade gliomas impact treatment strategies and patient outcomes.
• MR imaging techniques can provide insights into the genetic landscape of these tumors.
• Understanding genetic expression aids in differentiating true progression from treatment effects like pseudoprogression/pseudoresponse.

Conclusions:

• Integrating genetic information with MR imaging is essential for personalized glioblastoma treatment.
• Advanced neuroimaging techniques are vital for non-invasively characterizing tumor genetics.
• Accurate interpretation of post-treatment changes, guided by genetic data, improves patient management and prognostic accuracy.
