Can Biomarkers Help Guide Treatment For Lung Cancer?
Today a large, national clinical trial for non-small cell lung cancer was launched to validate whether a biomarker can predict clinical benefit in the treatment of this disease. Biomarkers, which are molecules found in the body that can signal an abnormal process or disease, would identify a target, known as epidermal growth factor receptor (EGFR). This receptor can be increased in some lung cancers due to the presence of extra copies of its coding gene. These extra copies can result in activation of tumor growth, so drugs that block this activation could have a significant impact on lung cancer treatment. This study, sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health, is called MARVEL (Marker Validation for Erlotinib in Lung Cancer) and will attempt to definitively establish the future value of selecting patients for treatment based on the presence or absence of EGFR activation. Approximately 1,200 lung cancer patients will be tested for the st
