Table 1 describes patients’ characteristics. BCLs were classified into three distinct groups: LBCLs (n = 25), indolent BCLs (n = 16) and MCL (n = 14). LBCL subtypes were as follows: RT (n = 10), transformed FL (tFL, n = 9), DLBCL-NOS (n = 3), primary mediastinal B-cell lymphoma (n = 1), high-grade B-cell lymphoma with double rearrangement of MYC and BCL2 (n = 1) and DLBCL-ALK-positive (n = 1). This evidence concerns the gene ALK and B-cell non-Hodgkin lymphoma.
