"Tumor DNA circulating in the bloodstream can help clinicians decide whether chemotherapy is right for their patients who have undergone surgery for stage II colon cancer, according to a breakthrough study published online in The New England Journal of Medicine and presented today at the 2022 American Society of Clinical Oncology Annual Meeting (Abstract LBA100).

If patients in the study’s guided group still had ctDNA present in their blood samples four to seven weeks..."
