Abstract: Immune response induced by parasites could inhibit tumor growth and promote apoptosis of tumor cells. The investigation into this character will provide new insights on the anti-tumor effect of parasites. The mechanism of parasite immune evasion may provide a reference for tumor research. Furthermore， some anti-parasitic drugs have shown antitumor effect indicating that the development of antitumor drugs may get inspiration from anti-parasitic drug studies.

Key words: Parasite, Antitumor
