Immunological studies in patients with malignant melanoma of the uvea.
Antibodies directed against different components of ocular melanoma cells were identified by indirect immunofluorescence in the sera of 12 patients with histologically proven malignant melanoma of the uvea. Antibodies reacing with autologous surface membrane antigens were found only in the sera of the 5 patients with the smallest tumors. The sera from most of the patients with small, large, or extraocular tumor contained antibodies directed against autologous cytoplasmic components while about one-half of the tests for antibodies reacting with allogeneic cytoplasmic antigens were positive. The incidence of positive tests with cytoplasmic antigens, in 67 patients with clinically diagnosed benign uveal nevi and 56 other individuals not showing evidence of proliferative lesions of uveal melanocytes, was 25%.
