O perfil molecular e citogenético é fundamental para a seleção do tratamento na LLC. Este protocolo aborda um subgrupo bem definido: pacientes com estado IGHV mutado, ausência confirmada de mutação TP53 e del(17p), que são clinicamente aptos.
LLC ativa com estado IGHV mutado, sem mutação TP53 e sem del(17p), em paciente clinicamente apto. O estado de mutação do IGHV é um fator prognóstico e preditivo fundamental que orienta diretamente o caminho terapêutico adequado neste 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].
