Abstract
Proteomic technologies can be applied to cancer research to detect differential protein expression that could find cancer biomakers. Lung cancer biomarker discovery is significant due to its anticipated critical role in early diagnosis, therapy guidance, and prognosis monitoring of lung cancer. Therefore, there is an indeed need to identify new biomarkers for early diagnosis and prognosis that could serve to open novel therapeutic means. This article briefly introduces the latest reports in proteomic studies of lung cancer. It contains diagnostic, prognostic, and predictive biomarkers, and a summary based on the most recent literature and our own work.
