Manganese superoxide dismutase and breast cancer recurrence: a Danish clinical registry-based case-control study, and a meta-analysis.
Manganese superoxide dismutase (MnSOD) inhibits oxidative damage and cancer therapy effectiveness.A polymorphism in its encoding gene (SOD2: Val16Ala rs4880) may confer poorer breast cancer survival, but data are inconsistent.We examined the association of SOD2 genotype and breast cancer recurrence (BCR) among patients treated with cyclophosphamide
