Expression of excision repair cross-complementation group 1 (ERCC1), p53, or thioredoxin (TRX) is reported to be correlated with resistance to platinum-based drugs. The authors evaluated whether ERCC1, p53, or TRX expression could predict progression-free and/ or overall survival in relapsed non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy.
This retrospective study indicates that immunostaining for ERCC1 may be useful for predicting survival in NSCLC patients receiving concurrent chemoradiotherapy with cisplatin and docetaxel, and can provide information critical for planning personalized chemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
