ABSTRACT: Objectives
Although platinum-based chemotherapy is widely used for advanced ovarian cancer (OC), genetic polymorphisms can influence the chemotherapeutic response. This study investigated the association between XRCC1 polymorphisms Arg194Trp, Arg280His, and Arg399Gln, and overall survival (OS) in OC patients who received platinum-based chemotherapy.Methods
We systematically searched PubMed, Embase, the Cochrane library, Chinese National Knowledge Infrastructure, Wanfang, and Weipu databases for relevant studies from inception to October, 2017. OS was calculated using a random-effects model. Sensitivity, subgroup, and publication bias analyses were also performed.Results
Five studies involving 1159 OC patients were included. When compared with 194ArgArg, 194TrpTrp (hazard ratio [HR] 1.09, 95% confidence interval [CI] 0.71-1.69, P?=?.69) and 194TrpArg (HR 1.00, 95% CI 0.78-1.28, P?=?.98) carriers were not associated with OS. Similarly, compared with 280ArgArg carriers, neither 280HisHis (HR 1.39, 95% CI 0.82 to -2.34, P?=?.22) nor 280HisArg (HR 0.98, 95% CI 0.73 to -1.31, P?=?.90) affected OS. Furthermore, there were no significant differences in OS between 399GlnGln (HR 1.00, 95% CI 0.46-2.16, P?>?.99), 399GlnArg (HR 1.05, 95% CI 0.81-1.37, P?=?.70), and 399ArgArg. Finally, subgroup analysis suggested that 399GlnGln significantly decreased OS when the percentage of III or IV cases was >80.0% (HR 1.79, 95% CI 1.22-2.62, P?=?.003), while OS was increased when this percentage was <80.0% (HR 0.47, 95% CI 0.28-0.79, P?=?.004).Conclusions
This study indicated that XRCC1 Arg194Trp, Arg280His, and Arg399Gln did not affect OS after platinum-based chemotherapy in OC patients. However, disease status could affect the relationship between Arg399Gln and OS in these patients.
