INTRODUCTION: Pathogenesis of large B-cell lymphomas (LBCL) and follicular lymphomas (FL) is a multistep process associated with the development of diverse DNA alterations and consequent deregulation of critical cellular processes. Detection of tumor-associated mutations within non-tumor compartments (mainly plasma) is the basis of the 'liquid biopsy' concept. Apart from tumor mutational profiling, quantitative analysis of circulating tumor DNA (ctDNA) allows longitudinal assessment of tumor burden. ctDNA-based technologies provide a new tool for tumor diagnostics and treatment personalization.
AREAS COVERED: Our review provides a comprehensive overview and summary of available ctDNA studies in LBCL and FL. The accuracy of ctDNA-based detection of lymphoma-associated DNA alterations is correlated to known LBCL and FL molecular landscape. Additionally, we summarized available evidence that supports and justifies the clinical use of ctDNA for lymphoma risk stratification, treatment response evaluation, and treatment response-adapted therapy. Lastly, we discuss other clinically important ctDNA applications: monitoring of lymphoma clonal evolution within resistance and/or relapse development and utilization of ctDNA for diagnostics in non-blood fluids and compartments (e.g. cerebrospinal fluid in primary CNS lymphomas).
EXPERT OPINION: Despite certain challenges, including methodological standardization, ctDNA holds promise to soon become an integral part of lymphoma diagnostics and treatment management.
