Description Malignant lymphomas represent a highly heterogeneous group of tumors with varied clinical behavior – from indolent to very aggressive forms with survival in the order of months. From the very beginning, these diseases are considered systemic, often occurring in several anatomical locations simultaneously. However, diagnosis and exact classification are usually inferred from a bio­psy of a single pathological lymph node or infiltrate, even though clinical experience shows that the bio­logical behavior of lymphoma is not necessarily identical across anatomical locations. In an effort to address this issue as well as the problem of bio­psy of not easily accessible compartments, circulating free DNA (cfDNA), which contains circulating tumor DNA (ctDNA) released from dead tumor cells, has been extensively studied in recent years. This DNA is easily accessible from liquid bio­psies such as blood or other patient‘s bodily fluids. Purpose: This article summarizes current scientific knowledge on cfDNA and ctDNA, particularly in the context of malignant lymphoma, and foreshadows its potential future uses. Conclusion: Detection and analysis of cfDNA represents a new approach that can lead to future improvements in all phases of lymphoma treatment from diagnostics to minimal residual disease monitoring.
