Correlation of the proportion of cells positive for caspase‐3 and bcl‐2 in Burkitt/Burkitt‐like lymphoma (BL/BLL). (a) BL/BLL patients are divided into three groups according to the proportion of cells positive for caspase‐3 (high caspase‐3 group, positively‐stained tumor cells, >30%; low caspase‐3 group, positively‐stained tumor cells, ≤30) and bcl‐2; high caspase‐3 and bcl‐2‐negative (HN), low caspase‐3 and bcl‐2‐negative (LN), low caspase‐3 and bcl‐2‐positive (LP). No patients in the high caspase‐3 group were bcl‐2‐positive. (b) Overall survival rate of BL/BLL patients with regard to the proportion of cells positive for caspase‐3 (high caspase‐3 group, positively‐stained tumor cells, >30%; low caspase‐3 group, positively‐stained tumor cells, ≤30) and bcl‐2; groups HN, LN and LP.
