There was no overall association between ERCC1 polymorphisms and lung cancer risk, with the adjusted odds ratios (AOR) of 1.26 [95% confidence interval (95% CI), 0.81-1.96] for the 8092C > A polymorphism (A/A versus C/C) and 0.93 (95% CI, 0.67-1.30) for the 19007T > C polymorphism (C/C versus T/T).
In conclusion, this study indicated no association between mRNA expression of the DNA-repair genes ERCC1 and XPD and risk of subsequent development of lung cancer.
We have previously reported that both homozygote carriers of the A-allele as well as homozygous carriers of a high-risk haplotype (which includes the AA genotype in ERCC1G19007A) were at increased risk of basal cell carcinoma, breast cancer, and lung cancer among Caucasians.
Gene-environment interactions between smoking and a haplotype of RAI, ASE-1 and ERCC1 polymorphisms among women in relation to risk of lung cancer in a population-based study.
We identified a sufficient number of epidemiologic studies on lung cancer to conduct a meta-analysis for genetic polymorphisms in nucleotide excision repair pathway genes, focusing on xeroderma pigmentosum group A (XPA), excision repair cross complementing group 1 (ERCC1), ERCC2/XPD, ERCC4/XPF and ERCC5/XPG.
Using immunohistochemistry in resected tumors, the International Adjuvant Lung Cancer Trial showed that high ERCC1 protein expression was associated with improved survival in patients who did not receive chemotherapy.
The haplotype at chromosome 19q13.2-3 encompassing the three SNPs ASE-1 G-21A, RAI IVS1 A4364G and ERCC1 Asn118Asn have been associated with risk of breast cancer and lung cancer.
In this study, we examined the expression of excision repair cross-complementation group 1 (ERCC1) protein in 90 completely resected lung cancer samples from patients who received adjuvant or neo-adjuvant platinum-based chemotherapy.
We tested whether genetic variants in the ERCC1 gene are associated with susceptibility to lung cancer and efficacy of platinum-chemotherapy in patients with small cell lung cancer (SCLC).
Using a panel of 20 lung cancer cell lines, including 15 NSCLC and 5 small cell lung cancers (SCLC), the mRNA expression levels for the RRM1, ERCC1 and ERCC2 genes were examined by quantitative real-time reverse transcription PCR.
These data suggested that ERCC-1 was involved in the resistance of cetuximab combined with DDP as overexpression of ERCC-1 prohibits the activation of EGFR pathway, which would facilitate the preselection of lung cancer patients for the treatment of cetuximab combined with DDP.
Our results suggest that polymorphism Asn118Asn in ERCC1, A67T in iASPP and Asn148Glu in APE1 may associated with early onset of lung cancer as well as some specific subtype of lung cancer.
In order to comprehensively capture common genetic variation in the ERCC1 gene, Caucasian data from the International HapMap project was used to assess linkage disequilibrium and choose four tagSNPs (rs1319052, rs3212955, rs3212948, and rs735482) in the ERCC1 gene to genotype 452 lung cancer cases, 175 H&N cancer cases, and 790 healthy controls.
Furthermore, a significant effect of SNPs in nucleotide excision repair pathway on lung cancer survival was observed among 185 stages III-IV patients treated with platinum-based chemotherapy without surgical operation: XPC rs2228000 (Ala499Val; P = 0.002) and ERCC1rs11615 (Asn118Asn; P = 0.012).
A Chinese case-control analysis comprising 370 cases and 388 controls was conducted to evaluate the effects of the high-risk diplotype predefined as PPP1R13L rs1970764(AA)-CD3EAP rs967591(GG)-ERCC1rs11615(AA) among Caucasians and three SNPs alone or other haplotypes combined for lung cancer risk.
