HLA-G and B-cell chronic lymphocytic leukemia: Interestingly, in our cohort, the “2-lncRNA risk model” was associated with both TTFT and OS independently of CLL-IPI, despite the fact that lnc-IRF2-3 and lnc-KIAA1755-4 expression levels were strongly associated with three out of five variables incorporated into the CLL-IPI stratification model (Binet stage, serum β2-microglobulin and IGHV SHM status) [71].
