XRCC3 Thr241Met gene polymorphism was associated with osteosarcoma risk, but XRCC3 Thr241Met CC genotype was not associated with Enneking stage, tumor location, and tumor metastasis.
However, the Thr241Met genotype of the XRCC3 polymorphism slightly increased the risk of local metastasis in breast cancer patients (OR 2.56, 95% CI 1.27-5.17).
