In early-stage cancer patients, a large portion of elevated cell-free DNA (cfDNA) originates from non-tumor sources, with the increase in cfDNA levels varying by cancer type and potentially linked to the liver's clearance efficiency. "...a large majority of cfDNA in cancer patients originates from non-tumor sources, and that the presence of early-stage cancer results in a multiplicative increase in the concentration of cfDNA originating from healthy tissue. The magnitude of the multiplicative increase is cancer-type specific and ranges from a ~1.3-fold increase in lung cancer, to a ∼12-fold increase in patients with liver cancer." #liquidbiopsy #oncology #ctdna #cfdna #biomarkers https://lnkd.in/g7pNbS8Q
