Background. Lung cancer is one of the leading causes of cancer-related deaths. Radiotherapy, either alone or with chemotherapy, is still the primary treatment for patients with non-small-cell lung cancer (NSCLC). There are variations in how patients with NSCLC respond to radiotherapy and how toxic the therapy is. DNA repair gene polymorphisms are related to cancer development; however, their association with radiotherapy outcomes remains unknown. We hypothesized that gDNA repair gene variation could affect the efficacy and toxicity of radiotherapy in patients with NSCLC. Methods. A total of 486 histologically confirmed patients with NSCLC were recruited from the Shengjing Hospital of China Medical University from July 2015 to September 2019. Eleven potentially functional single nucleotide polymorphisms (SNPs) in four DNA repair genes (XRCC1, XRCC2, XPD, and MSH2) were genotyped in these patients. A multiple factor logistic regression analysis was used to assess the association between these SNPs and the efficacy and toxicity of radiotherapy. Results. Three SNPs, rs25487 (XRCC1), rs3218556 (XRCC2), and rs13181 (XPD), were all significantly associated with the efficacy of radiotherapy. The allele frequencies of the rs25487 CC genotype (OR = 0.457, 95% CI = 0.259–0.804, p=0.006) and the rs3218556 AG or AA genotypes (AG genotype: OR = 0.664, 95% CI = 0.442–0.999, p=0.049; AA genotype: OR = 0.380, 95% CI = 0.181–0.795, p=0.008) were both significantly higher in the response group than in the nonresponse group. For rs13181, the radiotherapy efficacy was associated with the heterozygous genotype GT (OR = 1.663, 95% CI = 1.057–2.614,p=0.027). Statistically significant associations between radiation-induced toxic reactions and rs25487 (XRCC1), rs3218556 (XRCC2), and rs13181 (XPD) were also observed. The rs13181GT genotype was associated with lower toxic reactions than the TT genotype (OR = 1.680, 95% CI = 1.035–2.728,p=0.035). Conclusions. The variants rs25487 (XRCC1), rs3218556 (XRCC2), and rs13181 (XPD) all contribute to the efficacy and toxicity of radiotherapy in patients with NSCLC. Our findings may clarify the predictive value of DNA repair genes for prognosis in patients with NSCLC after radiotherapy. Further investigation of more genes and samples should be performed to confirm our findings.

Purpose This meta-analysis was performed to compare the activity, efficacy and toxicity of platinum-based versus non-platinum-based chemotherapy in patients with advanced non-small-cell lung cancer. Methods Randomized phase II and III clinical trials comparing first-line palliative platinum-based chemotherapy with the same regimen without platinum or with platinum replaced by a nonplatinum agent were identified by electronic searches of Medline, Embase, and Cancerlit, and hand searches of relevant abstract books and reference lists. Response rates, 1-year survival, and toxicity were analyzed. Subgroups of trials using third-generation agents were compared. Results Thirty-seven assessable trials were identified including 7,633 patients. A 62% increase in the odds ratio (OR) for response was attributable to platinum-based therapy (OR, 1.62; 95% CI, 1.46 to 1.8; P < .0001). The 1-year survival rate was increased by 5% with platinum-based regimens (34% v 29%; OR, 1.21; 95% CI, 1.09 to 1.35; P = .0003). No statistically significant increase in 1-year survival was found when platinum therapies were compared to third-generation-based combination regimens (OR, 1.11; 95% CI, 0.96 to 1.28; P = .17). The toxicity of platinum-based regimens was significantly higher for hematologic toxicity, nephrotoxicity, and nausea and vomiting, but not for neurotoxicity, febrile neutropenia rate, or toxic death rate. Conclusion Response is significantly higher with platinum-containing regimens. One-year survival was not significantly prolonged when platinum-based therapies were compared with third-generation-based combination regimens. Toxicity is generally higher for platinum-based regimens.
