Personalising care in oesophageal cancer care with liquid biopsy


The advent of ctDNA has the potential to be a game changer in some cancers, but limited data is available in oesophago-gastric cancers (OGC). The prognostic value of ctDNA and the potential for false positive results due to clonal haematopoiesis of indeterminate potential (CHIP) was recently reported in operable OGC.
