Lymphoma is a type of cancer that begins in immune system cells, called lymphocytes. It generally presents as a solid tumor of lymphoid cells and can develop in the lymph nodes, spleen, bone marrow, blood or other organs.
Combined studies in MYC-driven mouse lymphomas and human Burkitt lymphoma unravel an essential role for the B-cell antigen receptor in the control of tumour B-cell fitness both in vitro and in vivo, with possible biological and clinical implications.
Response criteria for disease assessment have important therapeutic and prognostic implications in clinical trials and in routine clinical practice. The Lugano classification has been used widely for evaluation of the response of patients with lymphoma to treatment, although the alternative Response Evaluation Criteria In Lymphoma 2017 (RECIL 2017) classification was recently proposed; these criteria are compared herein.
Accurate detection and monitoring of treatment responses is an essential element of the management of patients with lymphoma. In this Perspectives, the authors describe the evolution of lymphoma staging criteria and highlight unaddressed questions, which, if answered, will substantially improve the management of patients with lymphoma.
