The main treatments of lung cancer are surgical treatment techniques

chemotherapy and radiotherapy

which play a certain effect

but a smaller degree of improvement in patients with long-term survival. Targeted therapy technology

because of its safety

availabilityand low toxicity

has become one of the hotspots of the current lung cancer research. This article describes various types of target molecules in the active targeted therapy of lung cancer process and targeting mechanism

summarizes the targeting molecular's activation method and coupling mechanism

and also expounds the progress of targeting preparation at present.Finally

the clinical application prospect.
