colorectal curative following review cancer ctdna studiesZusammenfassung
Introduction Colorectal cancer is the fourth most common cancer in the UK.
There remains a need for improved risk stratification following curative resection.
Circulating-tumour DNA (ctDNA) has gained particular interest as a cancer biomarker in recent years.
We performed a systematic review to assess the utility of ctDNA in identifying minimal residual disease in colorectal cancer.
Methods Studies were included if ctDNA was measured following curative surgery and long-term outcomes were assessed.
Studies were excluded if the manuscript could not be obtained from the British Library or were not available in English.
Results Thirty-seven studies met the inclusion criteria, involving 3002 patients.
Hazard ratios (HRs) for progression-free survival (PFS) were available in 21 studies.
A meta-analysis using a random effects model demonstrated poorer PFS associated with ctDNA detection at the first liquid biopsy post-surgery [HR: 6.92 CI: 4.49–10.64 p < 0.00001].
This effect was also seen in subgroup analysis by disease extent, adjuvant chemotherapy and assay type.
Discussion Here we demonstrate that ctDNA detection post-surgery is associated with a greater propensity to disease relapse and is an independent indicator of poor prognosis.
Prior to incorporation into clinical practice, consensus around timing of measurements and assay methodology are critical.
Protocol registration The protocol for this review is registered on PROSPERO (CRD42021261569).
