Advancements in high-throughput sequencing methods within the last decade [11] possess made possible a primary, systematic breakthrough of gene fusions in solid malignancies [12C14], disclosing a diverse genomic landscaping rapidly. Gene fusions have already been discovered in a number of common carcinomas today, including those of the prostate, lung, breasts, neck and head, brain, epidermis, gastrointestinal tract, and kidney, which alongside the broadly noted gene fusions in thyroid and salivary gland tumors support the idea that gene fusions are essential towards the genomic landscaping of most malignancies.
