Another study showed that shorter cause-specific overall survival of DLBCL at 5 years correlated with gains in 18q gains.39 Although we identified gene copy number gains in18q, including MALT1 at 18q21.32 (20% of cases) and BCL2 at 18q21.33 (32% of cases), none of the genes in this region were associated with failure to achieve EFS24 (data not shown). This evidence concerns the gene MALT1 and diffuse large B-cell lymphoma.
