Sequencing of cancer autopsies and ctDNA

Tumor heterogeneity is a major obstacle for precision oncology strategies. To characterize inter-lesion heterogeneity in pre-treated cancers, we performed genetic and transcriptomic profiling of synchronous lesions from ten rapid autopsies comprising six cases of breast cancer, three of cholangiocarcinoma and one lung cancer case. For nine patients, we studied mutation representation in circulating cell-free DNA (cfDNA).

Dataset ID	Description	Technology	Samples
EGAD00001007040	The dataset contains high-throughput sequencing data derived from a cancer autopsy series of 10 patients. As part of this study, whole-exome sequencing and RNA-seq were performed for spatially distinct tissue biopsies from the patients. In addition, plasma samples from the patients were sequenced using a custom panelt to profile ctDNA. There are 106 files containing whole-exome sequencing data, 107 files containing RNA-seq data, and 9 files containing plasma sequencing data.		222
