Pan-cancer analysis aims to examine the similarities and differences among the genomic and cellular alterations found across diverse tumor types. [1] [2] International efforts have performed pan-cancer analysis on exomes and the whole genomes of cancers, the latter including their non-coding regions. In 2018, The Cancer Genome Atlas (TCGA ...
