There is no evidence to support the use of NER ERCC1 C118T/C8092A and ERCC2 Lys751Gln/Asp312Asn polymorphisms as prognostic predictors of platinum-based chemotherapies in NSCLC.
This study tested whether XPD Lys751Gln and XRCC1 T-77C polymorphisms were associated with survival in platinum-treated patients with advanced non-small-cell lung cancer (NSCLC).
We investigated the association of three DNA repair gene polymorphisms - Asn118Asn in ERCC1 (rs11615), Lys751Gln in ERCC2 (rs13181), and Asp1104His in ERCC5 (rs17655) - with the progression-free survival of 85 patients treated with platinum-based chemotherapy after surgery for NSCLC.
We evaluated seven single-nucleotide polymorphisms of six genes CDA Lys27Gln (A/C); CDA C435T; ERCC1 C118T; XRCC3 Thr241Met (C/T); XPD Lys751Gln (A/C); P53 Arg72Pro (G/C), and RRM1 C524T in 192 chemotherapy-naive patients with advanced NSCLC treated with cisplatin/gemcitabine-based regimen by TaqMan probe-based assays with 7300 Real-Time PCR System, using genomic DNA extracted from blood samples.
We investigated the impact of XPD Arg156Arg, XPD Asp312Asn, XPD Asp711Asp and XPD Lys751Gln gene polymorphisms on the efficacy of platinum-based chemotherapy in NSCLC patients.
This meta-analysis suggested that the ERCC1 C118T, ERCC2 Asp312Asn, and Lys751Gln may be useful biomarkers to predict the clinical outcomes of the platinum-based chemotherapy in NSCLC patients.
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.
The aim of this study is to investigate rs13181 ERCC2 (T>G) (Lys751Gln), rs12806698 RRM1 (-269C>A) and rs6759180 (located in the 5'UTR) RRM2 (10126436G>A) gene polymorphisms by using real time PCR technique in patients with NSCLC.
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.
