【Abstract】Objective To introduce the current research status, value and development future of Arg-Gly-Asp (RGD) peptides in diagnosis and treatment of neoplasms. Methods The current literatures on advances about RGD peptides in diagnosis and treatment of neoplasms were reviewed. Results RGD peptides, specificly recognizing and combining with integrin receptors, exist in extracellular matrix (ECM) of many kinds of organisms. After combining with integrin receptors, extrinsic RGD peptides can prevent tumor cells from adhering to ECM and migrating as the competitive inhibitor of intrinsic RGD peptides, suppress agiogenesis and induce tumor cells apoptosis, showing potential value of tumor specific imaging by targetal labelling neoplasms and treating tumors combining with other methods.Conclusion RGD peptides may be a new drug for diagnosis and treatment of neoplasms.
