The leukocyte migration inhibition assay was used to compare the antigenic reactivity of 3 M KCl extracts of human tumors. Many extracts demonstrated strong reactivity with patient leukocytes, whereas others demonstrated weak or no reactivity, Extracts prepared from primary tumors or local recurrent tumors were more antigenic than extracts from involved lymph nodes or pleural effusions. The least reactive preparations were extracts made from specimens of liver metastases obtained at autopsy. A large standard extract tested at a standard concentration was useful for the evaluation of antigenic reactivity of human tumor extracts. It served as a point of reference in simultaneous tests with one blood sample from each individual, thus eliminating the influence of patient variation on extract reactivity.
We tested 11 patients with choroidal melanomas and 32 control subjects for cell-mediated immunity to melanoma-associated antigens by an in vitro leukocyte migration inhibition assay. Five of seven patients with choroidal melanomas, who received two melanoma extracts used in this series of experiments, had significant leukocyte migration inhibition as compared with none of 17 normal subjects. Four of five melanoma patients who received a third melanoma extract had significant leukocyte migration inhibition as did three of four normal controls, indicating that the extract showed nonspecific inhibition. These data agreed with the concept that patients with choroidal melanomas have cell-mediated immunity to common melanoma-associated antigens.
