CLL

Most common adult leukemia; clonal CD5+/CD19+/CD23+ B-cell malignancy; del(17p)/TP53 mutation is highest-risk. Ibrutinib and venetoclax transformed CLL; obinutuzumab+venetoclax is first-line for unfit patients; pirtobrutinib is active in covalent BTK-inhibitor-resistant CLL.

Also known as: CLL, chronic lymphocytic leukemia, small lymphocytic lymphoma, SLL, B-CLL, CLL/SLL, del(17p) CLL, del(11q) CLL
