El perfil molecular y citogenético es fundamental para la selección del tratamiento en la LLC. Este protocolo aborda un subgrupo bien definido: pacientes con estado IGHV mutado, ausencia confirmada de mutación TP53 y del(17p), que son médicamente aptos.
LLC activa con estado IGHV mutado, sin mutación TP53 y sin del(17p), en un paciente médicamente apto. El estado de mutación de IGHV es un factor pronóstico y predictivo clave que orienta directamente la vía de tratamiento adecuada en este contexto.
CLL with mutated IGHV status and without TP53 mutation or del(17p) (if there was similar efficacy, panel is giving preference to time-limited therapies):
Fit patients: CIT according to age (FCR or BR) or ibrutinib [I, A]. Venetoclax plus obinutuzumab might be an alternative to BTKis, but data for fit patients are still pending [III, A].
Allogeneic stem cell transplantation (alloSCT) should be considered in:
Patients refractory to CIT and to novel inhibitor therapy, even for patients with a higher risk of non-relapse mortality [haematopoietic cell transplant comorbidity index (HCT-CI) score of 3] [III, B];
Treatment with chimeric antigen receptor T (CAR-T) cells or bi-specific T-cell engager (BiTE) antibodies within clinical trials could be an alternative to alloSCT for all three groups [V, B].
