title: Immune reactivity to Thomsen-Friedenreich antigen in patients with lung cancer detected by superoxide assay-leukocyte adherence inhibition test.
abstract: The immune reactivity to partially purified Thomsen-Friedenreich antigen was investigated in patients with lung cancer. The modified method of original leukocyte adherence inhibition test, termed superoxide assay-leukocyte adherence inhibition test, was used to detect the reactivity. The coded peripheral mononuclear cells from 34 of 50 (68%) patients with lung cancer showed a positive response to the antigen whereas in only 3 of 19 (16%) patients with benign pulmonary disease was there a reaction to the antigen. The same experiments were performed using the 3 m KCl extract of lung tumors as an antigen. In this case in 39 of 50 (78%) patients with lung cancer but in only 4 of 24 (17%) with benign pulmonary disease and in none of the breast cancer patients (0 of 17) was there a reaction to the antigen. These results strongly suggest that patients with lung cancer are sensitized to both Thomsen-Friedenreich antigen and tumor-associated antigens expressed in cancer cells of lung tissue origin.
