[Revision of JSH Guideline for Tumors of Hematopoietic and Lymphoid Tissues 2018: lymphoma].

The Japanese Society of Hematology has revised its clinical practice guidelines for Tumors of Hematopoietic and Lymphoid Tissues, and this version will be published in 2018. In the lymphoma section, the revised 4th edition (2017) of the WHO classification was adopted and reflected in all issues. The descriptions of all clinical questions (CQs) were thoroughly updated according to the latest published studies. The CQs were modified to reflect recent progress in the treatment of follicular, diffuse large B-cell, and Hodgkin lymphomas. Some of the treatment algorithms were amended aiming to become more useful tools in clinical practices. Because of rapid advances in lymphoma treatment, continuous revision of these clinical practice guidelines is critical.
