Immunosuppressive Acidic Protein in Patients With Testicular Cancer

Abstract
Serum immunosuppressive acidic protein was compared to lactic dehydrogenase as a marker for testicular cancer in 54 patients with testicular cancer, 62 with benign urological diseases and 203 healthy controls. The mean value of serum immunosuppressive acidic protein in patients with testicular cancer (598 ± 293 μg. per ml.) was statistically higher than that in patients with benign disease (429 ± 163 μg. per ml.) and healthy controls (368 ± 73 μg. per ml.). There were statistically significant differences in serum immunosuppressive acidic protein levels between controls and patients with stage 2 (p less than 0.0001) or stage 3 (p less than 0.001) testicular cancer, and between those with stage 1 and stage 2 (p less than 0.0001) or stage 3 (p less than 0.001) disease, respectively.
