Advances in the treatment of nanoparticles targeting to gastrointestinal tumors / 国际外科学杂志

ABSTRACT

Gastrointestinal tumors are the major disease that threaten human health.According to statistics,more than 700 000 people died every year because of gastric cancer,1/10 of all cancer mortality.Colorectal cancer incidence of malignant tumors,which ranked third,ranked fourth in cancer deaths.At now the treatment of gastrointestinal tunors mostly are operation,radiotherapy and chemnotherapy,but to spread of tumors,doctors still haven' t more better method.Nanoparticles have properties in the diagnosis and treatment of cancer,including their size-dependent properties,stability in solvent,ideal size for delivery within the body,and tunable surface chemistry for targeted delivery.Here,the author do an overview of nanoparticles in gastrointestinal tumors ablation.
