The role of Bruton's kinase inhibitors (BTKi) in accelerated Chronic Lymphocytic Leukemia (a-CLL): a case of successful response to acalabrutinib. J Basic Clin Physiol Pharmacol 2023; 34:401-404.

Abstract
OBJECTIVES The use of Bruton's tyrosine kinase (BTK) inhibitors has changed the clinical history of patients with chronic lymphocytic leukemia (CLL) in both naïve and relapsed/refractory settings. "Accelerated" chronic lymphocytic leukemia (a-CLL) is a relatively rare form of CLL representing less than 1 % of all CLL cases. a-CLL patients usually have a more aggressive course and a reduced overall survival was reported with conventional chemo-immunotherapy approaches. METHODS The role of Bruton Tyrosine Kinase-inhibitor, ibrutinib, in a-CLL is well established with encouraging preliminary results. RESULTS We report a case of a-CLL-treated first-line with second-generation BTKi, acalabrutinib with a prompt clinical response. As known, it is the first literature report on acalabrutinib in a-CLL highlighting the role of second-generation BTKi also in this high-risk setting. CONCLUSIONS Target therapies (Bruton Kinase inhibitors and Bcl2 inhibitors) have improved the therapeutic landscape of CLL. The availability of therapeutic targets requires greater diagnostic accuracy to choose the most appropriate therapy for each patient.

Abstract
The paper is devoted to changes in the 4th edition of the WHO classification of lymphoid tumors in the 2017 revision, to the principles of the structure and features of the classification. It discusses changes in the identification of new clinical and morphological categories and in the abolition of some previously existing ones. New information about lymphoid tumors, their immunophenotypic and molecular characteristics of classification importance are briefly outlined. The absolute need for molecular genetic studies for the diagnosis of certain lymphoproliferative diseases is underlined. The characteristics of lymphoid pretumor states are given.
