Developing a liquid biopsy protocol for cancer research at Princess Margaret
Official title: Liquid Biopsy Evaluation and Repository Development at Princess Margaret
Run by University Health Network, Toronto · NCT03702309 · Data updated 2026-11-12
This study is trying to create a simple way to collect blood samples from cancer patients to see if analyzing certain molecules in their blood can help doctors understand their cancer better and track how it changes over time.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults aged 18 and older with confirmed solid tumors or hematological malignancies, as well as those identified as high-risk for cancer.
✕Probably not a fit
Patients who do not have a confirmed cancer diagnosis or are not considered high-risk for cancer may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This initiative aims to establish a standardized liquid biopsy protocol at the Princess Margaret Cancer Centre, facilitating the collection of blood samples and archived tumor specimens for future research. By analyzing circulating cell-free nucleic acids (cfNA), including cfDNA and cfRNA, the study seeks to provide valuable diagnostic and prognostic insights throughout a patient's cancer journey. The protocol will enable non-invasive monitoring of tumor progression and treatment response over time, enhancing the understanding of cancer dynamics.
Why it matters
Potential benefit: If successful, this approach could lead to improved cancer diagnostics and personalized treatment strategies for patients.
How similar studies have gone: Other studies utilizing liquid biopsy techniques have shown promise in cancer diagnostics and monitoring, indicating a potential for success in this approach.
Who can join: the full rules
Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Patients with either histological confirmation of a solid tumor or hematological malignancy, OR patients identified as high-risk for cancer (based on identified aberration in cancer predisposition gene or on hormonal and/or family history without known aberration). 2. Patient must be ≥ 18 years old. 3. All patients must have signed and dated an informed consent form for this LIBERATE study. 4. If patients are being co-consented for a separate primary research study listed in Appendix I, they must fulfill the eligibility criteria for that separate primary research study. If there is a discrepancy in the eligibility criteria between protocols, the separate primary research study's criteria take precedence. Exclusion Criteria: None
