In conclusion, our findings suggest that ERCC1 rs11615 and ERCC1 rs2298881 genetic polymorphisms are significantly associated with poor response to chemotherapy and unfavourable survival of osteosarcoma.
In summary, our results suggested that the ERCC1 rs11615 and rs2298881 polymorphisms play important roles in the response to chemotherapy mediated by the DNA repair pathway and in the clinical outcome of osteosarcoma.
