Logistic regression analysis showed that XRCC1 T-77C, XRCC1 Pro206Pro polymorphism, cooking oil mist and soot exposure history and tumor-node-metastasis (TNM) stage were related to NSCLC occurrence for nonsmoking female patients.
The pairwise meta-analysis indicated that in terms of overall response ratio (ORR), ERCC1 (rs11615), XRCC1 (rs25487, rs1799782), and XPD (rs13181) polymorphisms are associated with the efficacy of platinum-based chemotherapy in NSCLC.
Crude odds ratios (ORs), Cox proportional hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) were adopted to assess the strength of association between XRCC1 polymorphisms and response rate, Overall survival (OS) and progression free survival (PFS) of advanced NSCLC treated with platinum-based chemotherapy.
The ERCC2 rs50872 T allele was associated with favorable but XRCC1rs25487 A allele with bad survival for advanced NSCLC in Chinese population, which may offer novel biomarkers for predicting clinical outcomes.
In this study, we explored the correlation between genetic polymorphisms in XPD and XRCC1 and the risk of non-small cell lung cancer (NSCLC) in the East Chinese Han population.
In summary, we suggest that GSTP1 Ile105Val and XRCC1Arg399Gln polymorphisms could influence the response to chemotherapy and sur-vival of advanced NSCLC.
A follow-up study of 610 non-small cell lung cancer (NSCLC) patients was conducted to investigate genetic polymorphisms associated with the DNA repair genes in relation to NSCLC survival; 6 SNPs were genotyped, including XRCC1 (rs25487 G>A), hOGG1 (rs1052133 C>G), MUTYH (rs3219489 G>C), XPA (rs1800975 G>A), ERCC2 (rs1799793 G>A) and XRCC3 (rs861539 C>T).
Clinical outcome of cisplatin-based chemotherapy is associated with the polymorphisms of GSTP1 and XRCC1 in advanced non-small cell lung cancer patients.
GSTP1 A313G and XRCC1Arg399Gln gene polymorphisms might influence the response to cisplatin-based chemotherapy and affect the clinical outcome of advanced NSCLC.
Resveratrol Enhances Etoposide-Induced Cytotoxicity through Down-Regulating ERK1/2 and AKT-Mediated X-ray Repair Cross-Complement Group 1 (XRCC1) Protein Expression in Human Non-Small-Cell Lung Cancer Cells.
However, the role of ERK1/2 and AKT-mediated XRCC1 expression in gefitinib alone or combination with an Hsp90 inhibitor-induced cytotoxicity in non-small cell lung cancer (NSCLC) cells has not been identified.
In conclusion, we found that the GSTP1 Ile105Val and XRCC1Arg194Trp were associated with better response to chemotherapy and longer survival of advanced NSCLC, compared to the wide-type genotype.
The results of our study suggest that the GSTP1 rs1695 and XRCC1rs25487 polymorphisms might affect the clinical outcome of patients with advanced NSCLC receiving cisplatin-based chemotherapy.
We aimed to determine the associations of genetic polymorphisms of excision repair cross-complementation group 1 (ERCC1) rs11615, xeroderma pigmentosum group D (XPD/ERCC2) rs13181, X-ray repair cross complementing group 1 (XRCC1) rs25487, XRCC3 rs1799794, and breast cancer susceptibility gene 1 (BRCA1) rs1799966 from the DNA repair pathway and multiple drug resistance 1 (MDR1/ABCB1) rs1045642 with response to chemotherapy and survival of non-small cell lung cancer (NSCLC) in a Chinese population.
We conducted a meta-analysis to investigate the association between polymorphisms in the XRCC1 gene and response rate of platinum chemotherapy in advanced NSCLC patients.
This study was aimed to establish a novel method to simultaneously detect expression of four genes, ribonucleotide reductase subunit M1(RRM1), X-ray repair cross-complementing gene 1 (XRCC1), thymidylate synthase (TS) and class III β-tubulin (TUBB3), and to assess their application in the clinic for prediction of response of non-small cell lung cancer (NSCLC) to chemoradiotherapy.
This study investigated polymorphisms of OGG1 Ser326Cys, APE1 Asp148Glu APE1-141T/G and XRCC1Arg399Gln for association with clinical outcome in 235 advanced inoperable nonsmall-cell lung cancer (NSCLC) patients after treatment with platinum-based chemotherapy.
These results indicate that XRCC1Arg399Gln and XPG His46His might significantly affect the clinical outcomes of platinum-based chemotherapy, highlighting the need for larger studies to confirm the role of these two SNPs in outcomes of NSCLC treatments.
We analyzed 17 SNPs in eight genes (ERCC1, ERCC2, ERCC3, ERCC4, ERCC5, XPA, XRCC1 and XRCC2) involved in DNA repair mechanisms and its association with outcome in NSCLC.
