Impact of preanalytical factors on liquid biopsy in the canine cancer model

Studies in dogs with natural cancer show blood sampling location affects tumor DNA results and that longitudinal monitoring detects relapse early.

Broad Institute study using dogs with spontaneous cancer demonstrates that blood draw site influences cfDNA tumor fraction and that longitudinal cfDNA monitoring detects impending relapse before clinical signs, supporting the canine model as a rapid validation platform for human liquid biopsy optimization.
