The pathological classification and clinical manifestations of lymphoma are complex, and there are many difficult cases. Therefore, the cooperation of different disciplines is needed in the process of diagnosis and treatment. Multi-disciplinary treatment (MDT) strategy can reduce the misdiagnosis and mistreatment, shorten the waiting time, promote the standardization and individualization of treatment, and improve the treatment outcome. In order to promote the development of MDT strategy for lymphoma in China, China Anti-Cancer Association Lymphoma Committee, Chinese Association for Clinical Oncologists and Medical Oncology Branch of Chinese International Exchange and Promotion Association for Medical and Health care co-organized the national experts committee to formulate "Clinical Practice Guideline for Multi-disciplinary Treatment Strategy of Lymphoma in China" .
