To provide a method of efficiently delivering cells having an anti-tumor activity to tumor tissues to evoke a stronger anti-tumor reaction, and a method of providing a more effective tumor regression effect, both in a cellular immunotherapy for cancer utilizing cells having an anti-tumor activity or antigen presenting cells for activating cells capable of exhibiting an anti-tumor activity. Provided are: a method of treating head and neck cancer, comprising administering an anti-cancer cell composition containing NKT cells activated in vitro with an NKT cell ligand into the tumor-feeding artery, and administering an NKT cell-stimulating agent containing antigen presenting cells treated with an NKT cell ligand through the upper respiratory tract mucous membrane; a use, in anti-cancer treatment of head and neck region, of the anti-cancer cell composition and the NKT cell-stimulating agent; a kit comprising the anti-cancer cell composition and the NKT cell-stimulating agent; and the anti-cancer cell composition.
