NCCN Guidelines® Insights: Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, Version 3.2022.

The treatment landscape of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) has significantly evolved in recent years. Targeted therapy with Bruton's tyrosine kinase (BTK) inhibitors and BCL-2 inhibitors has emerged as an effective chemotherapy-free option for patients with previously untreated or relapsed/refractory CLL/SLL. Undetectable minimal residual disease after the end of treatment is emerging as an important predictor of progression-free and overall survival for patients treated with fixed-duration BCL-2 inhibitor-based treatment.

Up to 8-year follow-up from RESONATE-2: first-line ibrutinib treatment for patients with chronic lymphocytic leukemia.

We report long-term follow-up from the RESONATE-2 phase 3 study of the once-daily Bruton's tyrosine kinase inhibitor ibrutinib, which is the only targeted therapy with significant progression-free survival (PFS) and overall survival (OS) benefit in multiple randomized chronic lymphocytic leukemia (CLL) studies. Patients (≥65 years) with previously untreated CLL, without del(17p), were randomly assigned 1:1 to once-daily ibrutinib 420 mg until disease progression/unacceptable toxicity (n = 136) or chlorambucil 0.5-0.

Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, Version 4.2020, NCCN Clinical Practice Guidelines in Oncology.

Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are characterized by a progressive accumulation of leukemic cells in the peripheral blood, bone marrow, and lymphoid tissues. Treatment of CLL/SLL has evolved significantly in recent years because of the improved understanding of the disease biology and the development of novel targeted therapies. In patients with indications for initiating treatment, the selection of treatment should be based on the disease stage, patient's age and overall fitness (performance status and comorbid conditions), and cytogenetic abnormalities.

NCCN Guidelines Insights: Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, Version 2.2019.

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.

Hairy Cell Leukemia, Version 2.2018, NCCN Clinical Practice Guidelines in Oncology.

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 gene is present in most patients with HCL.

Sequential azacitidine plus lenalidomide in previously treated elderly patients with acute myeloid leukemia and higher risk myelodysplastic syndrome.

The outcome of sequential azacitidine with lenalidomide has not been reported in previously treated patients with acute myeloid leukemia (AML) and higher risk myelodysplastic syndrome (MDS). This study describes a phase 2 study evaluating the safety and efficacy of this combination in elderly patients with AML and MDS with prior hypomethylating agent (HMA) and/or immunomodulatory agent exposure. Patients were treated on a 42-day cycle with azacitidine at 75 mg/m2 SQ/IV daily on days 1-7, followed by lenalidomide 50 mg orally daily on days 8-28.

Idelalisib, a selective inhibitor of phosphatidylinositol 3-kinase-δ, as therapy for previously treated indolent non-Hodgkin lymphoma.

Idelalisib (GS-1101, CAL-101), an oral inhibitor of phosphatidylinositol 3-kinase-δ, was evaluated in a phase I study in 64 patients with relapsed indolent non-Hodgkin lymphoma (iNHL). Patients had a median (range) age of 64 (32-91) years, 34 (53%) had bulky disease (≥1 lymph nodes ≥5 cm), and 37 (58%) had refractory disease. Patients had received a median (range) of 4 (1-10) prior therapies.

Southwest Oncology Group Study S0530: a phase 2 trial of clofarabine and cytarabine for relapsed or refractory acute lymphocytic leukaemia.

Clofarabine and cytarabine target different steps in DNA synthesis and replication, are synergistic in vivo, and have non-overlapping toxicities, making this combination a potentially promising treatment for acute lymphocytic leukaemia. Thirty-seven patients were treated. The median age was 41 years, 44% of patients were either in ≥2nd relapse or had refractory disease and 59% of patients had poor risk cytogenetics.

Second-line mitoxantrone, etoposide, and cytarabine for acute myeloid leukemia: a single-center experience.

The majority of patients with acute myeloid leukemia (AML) will require second-line chemotherapy for either relapsed or refractory disease. Currently, only allogeneic hematopoietic cell transplantation (HCT) offers a curative option in this setting and no preferred regimen has been established. The reported efficacy of second-line regimens is widely disparate, thus limiting informed clinical decision making.
