摘要: Biomarker discovery is one of the newly emerging innovations in diagnosis and treatment cancer many other diseases. Many research groups large pharmaceutical companies are actively engaged searching for novel biomarkers malignant diseases, which will make molecular analysis monitoring disease possible. technologies, including genomics, proteomics metabolomics, used to identify biomarkers. Among types cancers lung cancer--owing difficulty diagnosing at an early stage--urgently needs development as tools detection, well monitoring. Several DNA protein have been identified, but most previously discovered correlated with general process carcinogenesis immune responses. Therefore, these found cancers, thus not specific cancer. biomarker still needed, among possible samples, blood thought be ideal this it can collected easily a minimally invasive manner. studies now being conducted find blood. With advances methods technology, together considerable efforts diagnostic biomarkers, candidates discovered; leading diagnosis, efficient cancers.
