Moreover, focusing on histologic diagnosis, all types of NHL (FL, OR = 0.04, p < 0.001; LPL/WM, OR = 0.06, p = 0.008; MCL, OR = 0.12, p < 0.001; MZL, OR = 0.14, p = 0.004) were associated to lower second cancer rates than CLL patients. This evidence concerns the gene LPL and B-cell chronic lymphocytic leukemia.
