Study Details

Brief summary:

This study will collect, annotate, and sequence biospecimens (blood, tissue, urine, saliva and surgery drainage) from patients across different cancer types to detect molecular residual disease (MRD). Imaging scans and clinical data will also be gathered. This will allow for early cancer interception, and hopefully prolong relapse-free survival across tumor types. Results of ctDNA testing will be provided for clinical decisions and to determine eligibility for other linked interventional interception therapeutic studies, each of which will have a separate protocol.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

1. Patients with histopathological confirmation of cancer. Patients whose diagnosis are made by cytology may also be considered for this study. For tumor types that are typically diagnosed using unequivocal imaging findings or biomarker profiles (e.g. hepatocellular cancer, uveal melanoma), they can be eligible without histopathological or cytological confirmation.
2. Patients must have cancer that is planned for or has undergone curative intent treatment (e.g. surgery, definitive radiation, definitive chemoradiation, adjuvant radiation, adjuvant chemotherapy, adjuvant chemoradiation, etc). Curative intent treatment must be completed within 12 months of study entry. For patients on adjuvant/maintenance endocrine or biological therapy (e.g. bevacizumab, immunotherapy, etc), enrollment within 12 months of completion of curative intent treatment is allowed.
3. Patient must be ≥ 18 years old.
4. All patients must have signed and dated an informed consent form.

Exclusion Criteria:

1\. History of another active invasive cancer within 2 years prior to study enrolment. Exceptions include squamous and basal cell carcinoma of the skin and carcinoma in situ of the cervix, or malignancy that in the opinion of the investigator, is considered cured with minimal risk of recurrence within 2 years.
