| Summary: | Malignant hematologic diseases, also referred to as hematologic tumors, encompass a series of malignant proliferative disorders of the lymphopoietic system, including leukemia, lymphoma, multiple myeloma, and myeloproliferative neoplasms. The dysregulation of inflammatory factors or chronic inflammatory responses plays an indispensable role in the onset and progression of these tumors. The C-X-C motif chemokine receptor (CXCR) serves as a key mediator of immune-inflammatory responses. Through its specific regulatory mechanisms, CXCR is involved in the transduction and activation of various signaling pathways, thereby mediating the malignant biological characteristics of blood tumor cells, such as uncontrolled proliferation, differentiation, invasion, migration, autophagy, and apoptosis. In the bone marrow microenvironment, CXCR plays a pivotal role. This review systematically analyzes and elucidates the roles and mechanisms of the CXCR family in hematologic malignancies, aiming to provide new insights into the biological mechanisms and clinical significance of these diseases. The CXCR family holds great potential as a molecular marker for both fundamental research and the clinical diagnosis and treatment of hematologic malignancies.
