FFPE, buffycoat and cell free DNA from N. German esophagus cancer patients - 2021

We recruited 28 patients and sequenced samples from their FFPE tissue, full blood buffy coat and plasma cell free DNA from diagnosis and other, longitudinal time points. The cell free DNA was sequenced ultra-deeply. The IDT PanCancer panel was used for targeted enrichment. Aims: detection of primary tumor mutations in cell free DNA, overlap and difference in mutation profiles between primary tumor, metastases and cell free DNA.
