摘要:
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.

摘要:
The present invention provides an NKT cell stimulating agent containing antigen-presenting cells pulsed with an NKT cell ligand, to be administered submucosally in the upper airway. By submucosal administration in the upper airway, it is possible to stimulate NKT cells and stimulate immune reactions extremely efficiently with a small number of NKT cell ligand-pulsed antigen-presenting cells. By submucosal administration in the upper airway, NKT cells can be induced selectively in cervical lymph nodes.
