Ibrutinib for early-stage CLL: genetic risk factors and treatment outcome in the GCLLSG CLL12 trial
Patients with high-risk asymptomatic early-stage CLL (del(17p) or mutated TP53) do not derive an EFS benefit from early ibrutinib treatment. Watch-and-wait remains standard for early-stage CLL regardless of genetic subgroup; genetic test findings must not prompt early treatment
