Analysis of post-operative blood-derived plasma cfDNA reveals residual genomic alterations after incomplete resection of tumor. Genomic alterations were detected in post-op blood samples from tumors with incomplete tumor resection but not in those with complete resection. (A) depicts pre- and post-operative plasma CNV traces from PT03, a 14-year-old female spayed mixed breed dog that had incompletely excised metastatic pancreatic carcinoma. (B) depicts pre- and post-operative plasma CNV traces from PT01, a 12-year-old male intact West Highland White Terrier that had completely excised cystic renal carcinoma. All chromosomes shown were interrogated for cancer-associated genomic alterations by the test.
