MYC and prostate cancer: Furthermore, increased MYC amplification was not only associated with worse progression-free survival but also with reduced immunogenicity in metastatic tumors, as determined by the recovery of a reduced numbers of adaptive IR recombination sequencing reads from tumor RNAseq and tumor whole genome sequence files.<h4>Conclusions</h4>MYC amplification is associated with reduced tumor immunogenicity as assessed by the recovery of IR recombination reads from prostate cancer genomics files.
