Because available drugs already target so many of these receptors, our next step is to find out which drugs will kill lung cancer cells expressing these specific receptors.

Molecular targeted therapy has a advance development, the molecular targeted therapies drug for epidermal growth factor receptor (EGFR) present definite clinic effect.

CONCLUSION The N-succinyl-chitosan sample 6 has strong affinity to lung cancer cells, and can be used as a kind of drug targeting carrier to lung cancer.
