BCL2 and neoplasm: The correlationevaluation between Bcl-2/Bax expressionratio in tumoral tissues and knownprognostic variables showed that 77.8% ofpatients with high-grade tumor had Bcl-2/Bax ratio >1 and only 22.2% of patients withlow-grade tumor had the ratio more than one,thus, we observe the significant associationbetween Bcl-2/Bax expression ratio and histologicalgrade (p<0.05).
