Mutational landscape of uterine and ovarian carcinosarcomas implicates histone genes in epithelial–mesenchymal transition

Significance Some cancers, termed carcinosarcomas (CSs), have mixed cell types, with either epithelial or mesenchymal features. Sequencing the genomes of uterine and ovarian CSs demonstrated that these different cell types derive from a common precursor cell that has many mutations typical of epithelial cancers. In addition, we find that these tumors have a significant burden of point mutations and amplification of histone genes, suggesting a...
