ctDNA monitoring protocols
According to a growing body of research, circulating tumour DNA (ctDNA) assays are becoming an increasingly crucial part of cancer care. For instance, emerging real – world data shows that early detection of recurrence using ctDNA is being adopted more frequently in clinical practice, potentially leading to better patient outcomes.
Current best – known practices
Clinical application focus
The most immediate clinical application of ctDNA is for the assessment of treatment response and molecular residual disease (MRD). A significant advantage of ctDNA is that it can offer a simple approach to understanding a tumour’s spatial and temporal heterogeneity compared to traditional tissue genotyping. For example, in patients with advanced cancer, validated and adequately sensitive ctDNA assays have been shown to have utility in guiding treatment and surveillance strategies (European Society for Medical Oncology expert working group).
Pro Tip: Clinicians should prioritize using ctDNA for treatment response assessment and MRD detection as these areas have a strong evidence base.
As recommended by industry standards, leveraging ctDNA in these areas can lead to more personalized treatment plans.
Technology and methodology
Support Vector Machine (SVM) Model
Some computational analysis models like the Support Vector Machine (SVM) have shown potential in enhancing the utility of ctDNA analysis. While details in the given text don’t specifically cover its application in ctDNA in – depth, these types of models are part of the broader effort to develop more sophisticated ways to analyze ctDNA data.
MRD – EDGE
MRD – EDGE is a machine – learning – guided whole – genome sequencing (WGS) ctDNA single – nucleotide variant (SNV) and copy – number variant (CNV) detection platform. It is designed to increase signal enrichment. For example, it has been evaluated in serial plasma samples from an observational cohort of high aneuploidy but low mutational burden solid tumors. However, one limitation could be that the technology might be complex and costly to implement on a large scale.
Pro Tip: When considering using MRD – EDGE, assess whether the institution has the necessary expertise and resources to handle its implementation and interpretation.
MRDetect
Dr. Asaf Zviran and colleagues developed an ultra – sensitive, machine – learning – powered DNA – sequencing strategy named MRDetect. It searches across the genome for cumulative patterns of mutations and region – specific changes in the number of copies of ctDNA based on WGS information. In validation, it achieved accurate and sensitive ctDNA detection in tumor fractions (TFs) as low as 10⁻⁵, with 35× sequencing depth and assay – level specificity of 95 percent. A potential limitation is that it relies on WGS, which can be time – consuming and expensive.
Pro Tip: If using MRDetect, ensure a proper balance between the desired level of sensitivity and the associated costs and time.
ichorCNA
More recently, ichorCNA, a computational model, was developed to estimate ctDNA TF. It uses a probabilistic model, implemented as a hidden Markov model to simultaneously segment the genome, predict large – scale copy number alterations, and estimate the TF of a low – pass whole – genome sequencing (LP – WGS). One limitation is that it is based on certain assumptions about tumour purity, ploidy, etc., which may not hold true in all cases.
Pro Tip: When using ichorCNA, cross – validate its results with other methods to account for potential inaccuracies.
ACE
The ACE model, similar to ichorCNA, also considers tumour purity, ploidy, and somatic copy number alterations (SCNA) to estimate ctDNA TF. However, its performance may be affected by the quality and quantity of input data.
Pro Tip: Ensure high – quality input data when using ACE for more reliable results.
Pre – analytical and analytical procedures
Despite the potential of ctDNA, its use in routine clinical practice requires careful attention to pre – analytical processing and the selection of appropriate technology. For example, critical testing conditions identified from clinical trials include blood collection tube type, whole blood volume, time to sample processing, centrifugation steps, DNA extraction method, input DNA volume, and use of FDA – approved tests.
Key Takeaways:
- ctDNA is most valuable for treatment response assessment and MRD detection in current clinical applications.
- There are several advanced computational and machine – learning – based technologies for ctDNA analysis, each with its own strengths and limitations.
- Pre – analytical and analytical procedures play a crucial role in the accuracy of ctDNA results.
