Lymphoma is a group of heterogeneous hematological malignancies, among which most subtypes without specific tumor markers, and the evaluation of the efficacy and prognosis mainly depend on biopsy and imaging. Compared with other solid tumors, lymphoma cells were characterized by a trend to enter in peripheral circulation, and the diversity of immunoglobulin molecules can be monitored as marker, which can be applicable to liquid biopsy. With the advances in detection technology, research and application of liquid biopsy in lymphoma have attracted more attentions. In this review, the concept of liquid biopsy, base for liquid biopsy and its current situation of performance, progress of research and performace of liquid biopsy in lymphoma and so on are summarized.
