We showed that in childhood B-ALL, the intracellular VCR levels in lymphoblasts affected treatment outcomes. The intracellular VCR level was independent of leukaemia subtype but dependent on host ABCB1 G2677T genotype.
Similarly, no significant association was observed in the stratification analyses by ethnicity and control source. In conclusion, this meta-analysis suggests that ABCB1 G2677T/A polymorphism is not associated with genetic susceptibility to breast cancer.
