Certain carbohydrate antigens of malignantly trans- formed cells have been identified as markers for the onset of can- cer and have become targets for the development of anticancer vaccine therapies. For tumor antigens, many carbohydrate antigens belong to T-independent （TI） antigens. Carbohydrate conjugated to protein carriers can switch TI antigen to a T-dependent （TD） anti- gen. Attempts to add an innate immune response element （such as Toll-like receptor ligand） to carbohydrate TI-antigens have also been studied. Glycosylation inhibitors or small interfering RNA have also been used for antitumor and/or antiviral agents. This review aims at describing the vast spectrum of tumor carbohydrate antigens and strategies to develop cancer vaccines and drugs.
