Relationship between RAD51 135G ＞ C polymorphism and prognosis in triple-negative breast cancer patients / 中华内分泌外科杂志

ABSTRACT

Objective To investigate the relationship between RAD51 135G ＞ C polymorphism and prognosis in triple-negative breast cancer patients by retrospective analysis.Methods The clinical data of 62 triplenegative breast cancer patients were collected.The 62 cases underwent standard chemotherapy and radiotherapy after tumor resection from Jan.2004 to Dec.2010 in Affiliated Cancer Hospital of Zhengzhou University.RAD51 135G ＞ C polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RELP) technology.The survival curve about progress free and overall survival time were then made.Results The median progress free and overall survival time in triple-negative breast cancer patients with or with-out RAD51 135G ＞ C polymorphism were(77.00 ±5.55)and(89.00 ± 10.40) months vs(99.00 ±4.26)and (103.00 ±4.30) months.The difference had statistical significance(P =0.039 and 0.015 respectively).Conclusion RAD51 135G ＞ C polymorphism is related with prognosis of triple-negative breast cancer patients,which might be a prognostic factor for breast cancer.
