About this trial
This study investigates if circulating tumor DNA (ctDNA) and other tumor-related molecules/chemicals released in the blood can help doctors predict if colorectal cancer may come back or spread. Tumors shed DNA and other cancer related chemicals into the blood that can be identified and studied further to provide information about the cancer. Information gathered from this study may help researchers better understand if ctDNA found in the blood can predict whether colorectal cancer may come back or spread.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age ≥ 18 years.
Histological/cytological confirmation of colorectal adenocarcinoma.
Patients with any stage colorectal adenocarcinoma deemed potentially eligible for curative intent treatment. Patients with stages II-IV colorectal cancer post-R0 resection may also be enrolled onto the protocol any time before or up to 3 months post-surgery and prior to initiating adjuvant therapy.
Ability to understand and the willingness to sign a written informed consent document.
Disqualifiers
Known active malignancies other than colorectal adenocarcinoma that may interfere with detection and / or interpretation of circulating plasma markers. Patients with known clonal hematopoiesis of indeterminate potential are eligible.
Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
Trial population
Patients with colorectal cancer at MD Anderson Cancer Center.

Trial outcomes
Primary outcomes
Analysis of deoxyribonucleic (DNA), ribonucleic acid (RNA), and proteomic alterations from plasma
To detect circulating tumor DNA (ctDNA) in plasma samples from patients with colorectal cancer (CRC) who have completed curative therapies (i.e. minimal residual disease) towards predicting recurrence earlier than the current standard of care utilizing the CRC23 assay and the LUNAR assay from Guardant Health technology.
Detection of recurrences post completion of curative therapies
To detect ctDNA in plasma samples from patients with CRC who have completed curative therapies (i.e. minimal residual disease) towards predicting recurrence earlier than the current standard of care utilizing the CRC23 assay and the LUNAR assay from Guardant Health technology.
Secondary outcomes
Changes in cancer-specific plasma alterations during neoadjuvant, adjuvant therapies and surveillance
Will assess the association between changes in circulating molecules and response in patients undergoing neoadjuvant therapy by linear or logistic regression models
Disease free survival (DFS)
Overall survival (OS)
Other outcomes
Optimal combination of cancer-specific plasma DNA, RNA and / or proteomic alterations for early detection of recurrences
Sensitivity, specificity, positive predictive and negative predictive values of cancer-specific plasma alterations in detecting recurrences
Correlation between cancer-specific alterations in plasma and tissue and either with outcomes including DFS & OS
Nature and frequency of detection of incidental non-colorectal cancer related DNA, RNA and / or proteomic alterations
