  • Title: Proteomic approaches in lung cancer biomarker development.
    Author: Cho JY, Sung HJ.
    Journal: Expert Rev Proteomics; 2009 Feb; 6(1):27-42. PubMed ID: 19210125.
    Abstract:
    Biomarker discovery is one of the newly emerging innovations in the diagnosis and treatment of cancer and many other diseases. Many research groups and large pharmaceutical companies are actively engaged in searching for novel biomarkers for malignant diseases, which will make molecular analysis and monitoring of disease possible. Many technologies, including genomics, proteomics and metabolomics, are used to identify biomarkers. Among the many types of cancers and diseases, lung cancer--owing to the difficulty in diagnosing the disease at an early stage--urgently needs development of novel biomarkers as tools for early diagnosis and detection, as well as disease monitoring. Several DNA and protein biomarkers have been identified, but most previously discovered biomarkers are correlated with the general process of carcinogenesis and immune responses. Therefore, many of these biomarkers are found in other types of cancers, and thus are not specific to lung cancer. Therefore, novel lung cancer biomarker discovery is still needed, and among the many possible types of samples, blood is thought to be ideal for this discovery as it can be collected easily in a minimally invasive manner. Therefore, many studies are now being conducted to find lung cancer biomarkers in the blood. With advances in methods and technology, together with the considerable efforts to find early and novel diagnostic lung cancer biomarkers, many candidates will be discovered; leading to early diagnosis, detection, monitoring and efficient treatment of lung cancers.
