[Clinical Application and Research Progress of Circulating Tumor DNA in Diffuse Large B-Cell Lymphoma--Review].

Diffuse large B cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma, its diagnosis and prognosis evaluation mainly depends on tissue biopsy and imaging examination. As a part of liquid biopsy, circulating tumor DNA (ctDNA) is a novel noninvasive and real-time tumor-specific biomarker, which can reliably reflect the comprehensive tumor genetic profiles, and it plays an important role in assisting early diagnosis, monitoring the curative effect, prognosis evaluation and prediction of recurrence of DLBCL. This review summarized recent research progress of ctDNA in DLBCL.
