Mutational Profile Evaluates Response and Survival to First-Line Chemotherapy in Lung Cancer.

ABSTRACT: Evaluating the therapeutic response and survival of lung cancer patients receiving first-line chemotherapy has always been difficult. Limited biomarkers for evaluation exist and as a result histology represents an empiric tool to guide therapeutic decision making. In this study, molecular signatures associated with response and long-term survival of lung cancer patients receiving first-line chemotherapy are discovered. Whole-exome sequencing is performed on pretherapeutic tissue samples of 186 patients [145 non-small cell lung cancer (NSCLC) and 41 small cell lung cancer (SCLC)]. On the basis of genomic alteration characteristics, NSCLC patients can be classified into four subtypes (C1-C4). The long-term survival is similar among different subtypes. SCLC patients are also divided into four
