Mantle cell lymphoma (MCL) is a heterogenous disease with historically relative poor outcomes. However, new treatment strategies seem to be improving the prognosis for patients. Although no universally accepted standard of care exists, options for patients with newly diagnosed MCL include intensive and nonintensive strategies. Generally, intensive strategies produce more durable remissions and are selected for younger patients, whereas nonintensive strategies are most appropriate for older patients or patients with comorbidities. However, new options are closing the treatment gap between intensive and nonintensive strategies. Treatment options are also increasing for patients with relapsed/refractory MCL and include agents targeting the microenvironment and the B-cell receptor signaling pathway.

Hairy cell leukemia (HCL) is a rare type of indolent B-cell leukemia, characterized by symptoms of fatigue and weakness, organomegaly, pancytopenia, and recurrent opportunistic infections. Classic HCL should be considered a distinct clinical entity separate from HCLvariant (HCLv), which is associated with a more aggressive disease course and may not respond to standard HCL therapies. Somatic hypermutation in the IGHV gene is present in most patients with HCL. The BRAF V600E mutation has been reported in most patients with classic HCL but not in those with other B-cell leukemias or lymphomas. Therefore, it is necessary to distinguish HCLv from classic HCL. This manuscript discusses the recommendations outlined in the NCCN Guidelines for the diagnosis and management of classic HCL.

Chronic lymphocytic leukemia (CLL) is generally characterized by an indolent disease course. Histologic transformation (also known as Richter's transformation) to more aggressive lymphomas, such as diffuse large B-cell lymphoma or Hodgkin lymphoma, occurs in approximately 2% to 10% of patients and is associated with a poor prognosis. These NCCN Guidelines Insights discuss the recommendations for the diagnosis and management of patients with histologic transformation.
