The “Hematological Cancer Pathophysiology: An Interdisciplinary Approach” is the tenth volume of the “Interdisciplinary Cancer Research” series, publishes a comprehensive volume on the pathophysiology of hematological cancers. This volume has an interdisciplinary approach in hematological cancers, including myeloproliferative neoplasms, T-cell lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, and intraocular lymphoma. Waldenstrom macroglobulinemia and IgG4-related diseases are also discussed in the last chapters. This interdisciplinary series is of special value to researchers working on hematology and oncology. This is the main concept of Cancer Immunology Project (CIP), which is a part of Universal Scientific Education and Research Network (USERN). This interdisciplinary book will be of special value to hematologists and oncologists who wish to extend their knowledge on hematological cancers.
