Three of them were treated with stereotactic radiosurgery (SRS) with complete response even of the untreated lesions. As the patient was BRAF-mutated, she was started on dabrafenib/trametinib. After 8 months she developed new brain metastases, which again responded to a new treatment with SRS. As after 7 months additional lesions appeared, she was treated with whole brain radiotherapy and was started on nivolumab.

However, like any treatment, radiation has significant acute and long-term side effects including secondary malignancies.

Genomic susceptibility is thought to be responsible for approximately 40% of the clinical variability observed. In the era of precision medicine, the link between genetic susceptibility and radiation-induced side effects is further strengthening. Genome-wide association studies (GWAS) have begun to identify single-nucleotide polymorphisms (SNPs) attributed to overall and tissue-specific toxicity following radiation for treatment of breast cancer, prostate cancer, and other cancers. Here, we review the use of GWAS in identifying polymorphisms that are predictive of acute and long-term radiation-induced side effects with a focus on chest, pelvic, and head-and-neck irradiation.
