Low expression of miR-34a was associated with a significantly shorter OS (p < 0.001) in patients with leukemic and nodal MCL who also had high MYC expression (median OS for leukemic and nodal cases: 9 and 21 months, respectively) in comparison to patients with only one of these factors (median OS for leukemic and nodal: 58 and 49 months, respectively) or none of them (median OS for leukemic and nodal: not reached and 64 months, respectively). Here, MYC is linked to mantle cell lymphoma.
