The Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium project, led by the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA), coordinated the sequencing and analysis of 2,583 tumor whole genomes across 38 cancer types. This impressively large project, comprising many working groups focusing on various molecular or genetic features of cancer, has generated valuable data for the cancer research community that will continue to be mined for many years to come.
