Clinical and pathological features of MCL cases analyzed.

Cases were progressively numbered and sorted in high and low CK2 expressing subgroups. Scoring method used was: 0 = 0–5% positive cells; 1 = 6–33% positive cells; 2 = 34–66% positive cells; 3 = 67–100% positive cells. Cases were defined as CK2 high if the sum of the scores for CK2α and CK2β was equal to or > 3 and CK2 low if the sum was < 3; MIPI = mantle cell international prognostic index according to (44). M = male; F = female; FISH =  fluorescence in situ hybridization; ND = not determined; NA = not assessable; P-STAT3  =  Ser 727 phosphorylated STAT3.
