Liquid biopsy for colorectal cancer could guide therapy for tumors

(Washington University School of Medicine) A new study from Washington University School of Medicine in St. Louis demonstrates that a liquid biopsy examining blood or urine can help gauge the effectiveness of therapy for colorectal cancer that has just begun to spread beyond the original tumor. Such a biopsy can detect lingering disease and could serve as a guide for deciding whether a patient should undergo further treatments due to some tumor cells evading an initial attempt to eradicate the cancer.
