Official title
A Study of the Role of Circulating Tumor DNA in Predicting the Likelihood of Organ Preservation or Pathologic Complete Response After Neoadjuvant Therapy for Rectal Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This prospective observational, non-therapeutic study for patients with T3, T4, or node positive rectal cancer eligible to undergo total neoadjuvant therapy. This research study involves the collection of data and biospecimens (blood and tissue) to see if the presence of circulating tumor DNA (genetic material) ctDNA will help monitor rectal cancer more closely and potentially detect a recurrence before routine scans, performed per standard of care C2i Genomics, a biotechnology company, and the Spier Foundation are supporting this research study by providing funding for the study.
