Brief Summary

In this research study, the investigators are looking to see if the circulating tumor DNA (genetic material), also known as ctDNA, in the blood will help them predict whether the participant's cancer ...

Detailed Description

In this research study, the investigator are performing blood draws to see if the presence or absence of circulating tumor DNA (ctDNA), the genetic material in the participant's cancer's cells, will h...

Eligibility Criteria

Inclusion

  • Participants must have achieved a clinical complete response (cCR) within 3 months of last therapy - defined as absence of residual ulceration, mass or mucosal irregularity at endoscopic assessment - following neoadjuvant therapy with chemoradiation or chemotherapy followed by radiation for stage I, II, or III non-metastatic rectal cancer. (Whitening of the mucosa with presence of telangiectasia will be accepted as cCR.)
  • Participants must have original tumor tissue (formalin-fixed, paraffin-embedded specimens) available for analysis
  • Participants must be 18 years of age or older.
  • Participants must be able to understand and willing to sign a written informed consent document.
  • Participants must have received long course chemoradiation to 40-54 Gy.
  • Participants must have received at least 4 cycles of FOLFOX
  • Participant must be no more than 3 months past the conclusion of initial chemoradiation of rectal cancer (i.e., end of chemoradiation).

Exclusion

  • Participants may not have any other organ cancer evident at the time of enrollment.
  • Participants may not have any other concurrent serious illness that makes participation on this study impractical or clinically inappropriate.
