Colorectal Cancer Plasma for Liquid Biopsy and Tumour Immunology Research
Colorectal Cancer Plasma is collected from IRB-consented donors clinically diagnosed with colorectal cancer and processed within one day of collection to preserve circulating tumour DNA, extracellular vesicles, proteins, cytokines and metabolites. Colorectal cancer is a neoplastic disease that develops through progressive accumulation of somatic alterations — classically involving APC, KRAS, TP53 and mismatch repair genes — with tumour-immune interactions shaping progression and response to therapy. Plasma is acellular and is the standard matrix for liquid biopsy and soluble-analyte work.
Tumour Biology and Why Plasma
- Circulating tumour DNA (ctDNA) enables non-invasive detection of somatic alterations including KRAS, NRAS, BRAF V600E and PIK3CA, and detection of resistance mutations emerging on anti-EGFR therapy.
- Plasma rather than serum for cell-free DNA: serum carries far more background leukocyte-derived genomic DNA generated during clotting, which dilutes the tumour fraction.
- Minimal residual disease and recurrence monitoring after surgery is one of the most active applications of ctDNA in colorectal cancer, and benefits from serial collections.
- Methylation markers such as methylated SEPT9 and related cell-free DNA methylation signatures underpin non-invasive screening research.
- Protein tumour markers including CEA and CA 19-9 support marker validation and combined protein-plus-ctDNA panel development.
- Tumour immunology: microsatellite instability-high and mismatch repair-deficient tumours are immunotherapy-responsive; soluble checkpoint molecules, cytokines and chemokines support immune evasion and response research.
Donor Stratification Available
- Primary tumour site: colon versus rectum, and right- versus left-sided colon where documented
- Stage at collection, including localised versus metastatic disease
- Mutation status where available: KRAS, NRAS, BRAF
- Mismatch repair / microsatellite instability status where available
- Treatment status and line of therapy: treatment-naive, post-surgical, on chemotherapy, on anti-EGFR or anti-VEGF therapy, on immune checkpoint inhibitor, or post-progression
- Hereditary syndrome context where documented, including Lynch syndrome or familial adenomatous polyposis
- Longitudinal or serial collections from the same donor, on request
- Matched healthy controls available
