Radiogenomics: towards a personalized radiation oncology

Area of Science:

• Genomics
• Radiation Biology
• Radiogenomics

Background:

• Pediatric cancer survivors treated with radiation face risks of long-term side effects like cardiac disease and secondary malignancies.
• Genetics significantly influences individual susceptibility to radiation-induced side effects, establishing the field of radiogenomics.
• Early candidate gene studies yielded limited results, but recent genome-wide association studies are identifying key genes.

Purpose of the Study:

• To evaluate the field of radiogenomics in the context of recent advancements in genomics and radiation biology.

Main Methods:

• Review of recent developments in genomics and radiation biology.
• Analysis of genome-wide association studies (GWAS) for radiosensitivity.
• Evaluation of candidate gene studies.

Main Results:

• Genome-wide association studies are beginning to identify genetic variants associated with radiosensitivity.
• Genomic technologies are becoming more accessible and cost-effective, facilitating broader research.
• Understanding genetic factors is crucial for predicting patient susceptibility to radiation side effects.

Conclusions:

• Radiogenomics is an evolving field crucial for understanding individual radiosensitivity.
• Continued progress in genomic technologies will enhance the identification of genes influencing radiation response.
• Improved understanding of radiogenomics will lead to better patient counseling regarding adverse effects.
