This study shows that elevated cfDNA and fragment shortening in cancer are due to saturated hepatic clearance, not tumor burden alone.

The paper develops methods to improve marker selection for ctDNA analysis by refining phylogenetic models and quantifying clonal frequencies through optimization.

This study models how spatially variable cell death in solid tumors affects ctDNA composition and clonal representation, showing potential biases in liquid biopsy profiles.

This study tracks ctDNA and immune cell changes in lung cancer patients on immunotherapy to identify molecular responses and immune-related toxicities.
