Peripheral gammadelta T cells derived from healthy donors were found to exhibit cytotoxicity against a variety of tumor cell lines in vitro, including CNE2, which was established from nasopharyngeal carcinoma (NPC). The anti-tumor effects were further studied in a mouse model. Control nude mice inoculated s.c. with 5 x 10(6) CNE2 cells regularly developed hypodermal tumors, which progressively increased in size, and animals had a mean survival of 35 +/- 3.4 days. Tumor growth was arrested and tumor size was reduced after animals were infused with 5 x 10(7) gammadelta T cells derived from a healthy donor. The anti-tumor effects were temporary, however, and tumor growth was resumed after about 1 week in a group of the animals that had been given a single dose of gammadelta T cells. In another group of animals given 2 doses of gammadelta cells 1 week apart, resumption of tumor growth was delayed for a further week. Mean survival of the 2 groups was increased to 61 +/- 15.7 and 74 +/- 12.9 days, respectively. Immunohistology revealed an accumulation of infused cells in tumors attended by focal tumor necrosis in specimens taken 2 days after infusion. Infiltrative cells virtually disappeared from tumor tissues 6 days after infusion, accompanied by increased mitotic indices of tumor cells. These temporal relationships suggested that the accumulation of infused gammadelta T cells in hypodermal tumors was responsible for the observed anti-tumor effects.
