Application of monoclonal antibodies for diagnosis and treatment of human digestive cancer

Radioimmunoscintigraphic applications of monoclonal antibodies (Mabs) for noninvasive detection and visualization of target tumors have grown immensely, and it suggests that Mabs can reach specifically to the targeted tumors in the human body. Radionuclides, cytotoxic drugs and anti-cancer drugs can be coupled to these specific MAbs to detect the extent of disease and/or to treat the tumors. Many of such immunoconjugates were studied for targeting therapy for cancer in animal experiments and some of them have applied to human. In this paper, we described the existing status of application of Mabs for diagnosis and immunotargeting therapy of digestive cancers. (author)
