E. Kubota et al., LOCOREGIONAL IMMUNOTHERAPY OF HEAD AND NECK CANCERS UTILIZING ALLOGENEIC SPLEEN-CELLS - A REPORT OF 2 CASES, Biotherapy, 6(3), 1993, pp. 175-182
Frozen-stored human spleen cells (SC) cultured with streptococcus prep
aration OK-432 acquired direct cytotoxicity to autologous as well as a
llogeneic tumor cells. The activated cells started to produce cytocida
l cytokine TGIF, which is distinct from previously known cytokines. We
examined the possibility of allogeneic adoptive immunotherapy (AIT) u
sing these OK-432-stimulated spleen cells (OK-SC) in two cancer patien
ts. Rapid necrosis of cancer tissue and remarkable decreases of tumor
markers in tumor effusion were observed. There were no severe side eff
ects.
