An ERCC4 Regulatory Variant Predicts Grade‐
IJC International Journal of Cancer An ERCC4 regulatory variant predicts grade-3 or -4 toxicities in patients with advanced non-small cell lung cancer treated by platinum-based therapy Ruoxin Zhang1, Ming Jia1,2, Yuan Xu1,2, Danwen Qian1,2, Mengyun Wang1, Meiling Zhu3, Menghong Sun1,4, Jianhua Chang1,5 and Qingyi Wei 1,2,6 1 Cancer Institute, Collaborative Innovative Center for Cancer Medicine, Fudan University Shanghai Cancer Center, 270 Dong An Road, Xuhui District, Shanghai, 200032, People’s Republic of China 2 Department of Oncology, Shanghai Medical College, Fudan University Shanghai Cancer Center, 270 Dong An Road, Shanghai, 200032, People’s Republic of China 3 Department of Oncology, Xinhua Hospital affiliated to Shanghai Jiaotong University, No. 1665 Kong Jiang Road, Shanghai, 200092, People’s Republic of China 4 Department of Pathology, Fudan University Shanghai Cancer Center, 270 Dong An Road, Shanghai, 200032, People’s Republic of China 5 Department of Medical Oncology, Fudan University Shanghai Cancer Center, 270 Dong An Road, Shanghai, 200032, People’s Republic of China 6 Duke Cancer Institute, Duke University Medical Center, 10 Bryn Searle Dr., Durham, NC 27710, USA Platinum-based chemotherapy (PBC) in combination with the 3rd generation drugs is the first-line treatment for patients with advanced non-small cell lung cancer (NSCLC); however, the efficacy is severely hampered by grade 3–4 toxicities. Nucleotide excision repair (NER) pathway is the main mechanism of removing platinum-induced DNA adducts that contribute to the toxic- Cancer Epidemiology ity and outcome of PBC. We analyzed data from 710 Chinese NSCLC patients treated with PBC and assessed the associations of 25 potentially functional single nucleotide polymorphisms (SNPs) in nine NER core genes with overall, gastrointestinal and hematologic toxicities.
