Study Details

Brief summary:

Patients who have undergone curative treatment may be at risk of relapse. This study will collect, annotate, and sequence biospecimens (blood, stool, and tissue) from patients across different tumor types to detect molecular residual disease (MRD) before metastases become radiographically or clinically detectable. This will allow for early cancer interception, and hopefully prolong relapse-free survival across tumor types.

Interventions and Outcome Measures

Arms

NIP IT!

Patients with early stage or locally advanced disease that is planned for or have undergone curative treatment will have next-generation sequencing (NGS)-based ctDNA analysis performed on blood samples to determine minimal residual disease (MRD). Blood samples, stool samples, and additional archival/fresh tumor specimens will be collected for banking and future research purposes.

Primary outcome measure

  • Change from Baseline in ctDNA collected from biospecimens [ Time Frame: Through study completion, an average of 4 years ]
