Liquid biopsy in hemato-oncology. Leading Opinions. Applications of cfDNA analysis in lymphomas include: i identification of tumor mutations in a biopsy-free manner; ii tracking tumor clonal evolution and identification of mutations causing resistance to treatment; and iii monitoring of residual disease after therapy.
However, multiregional sequencing showed that the diagnostic tissue biopsy might be subject to a selection bias resulting from spatial heterogeneity and, therefore, might not be representative of the entire tumor genetics. Accessing the blood stream has also clear sampling advantage in the serial monitoring of treatment emergent resistant mutations in real time. The biopsy-confirmed mutations missed in ctDNA i. Next-generation sequencing methods relied on either the VDJ sequences from the immunoglobulin receptors or the mutational profile as tumor fingerprints to be dynamically quantified for MRD estimation Fig.
Furthermore, they suggested a prognostic role for monitoring ctDNA during and after therapy. This includes limited sensitivity in low tumor burden settings and reduced applicability because of SHM, leading to difficulty identifying clonotypic sequences. Pretreatment ctDNA levels correlate with clinical measures of tumor burden.
Changes of ctDNA load during treatment correlated with patient outcome Fig. In a large study conducted by highly sensitive next-generation sequencing method, lymphoma-specific immunoglobulin gene segments have been identified in cHL at initial diagnosis or recurrence, and assessed the ability of detecting such lymphoma-specific sequences in peripheral blood. Our results suggest that ctDNA is a novel tool for real-time genotyping and a potential precision medicine biomarker in cHL.
Despite the fact that many of these techniques have been developed as valuable noninvasive, appropriate, and real-time monitoring tools, none of these techniques has been translated yet into the clinical practice. Undoubtedly, future studies to investigate whether monitoring of ctDNA can be used to improve clinical outcomes for patients with aggressive B-cell lymphomas are warranted. New opportunities that go beyond assessment of VDJ recombination are also being explored, and ultrasensitive assays that can assess for genotypic tumor DNA in the blood are under development as well.
