Anti-HNK-1 monoclonal antibody (MAb) was reactive with non-cancerous and cancerous prostatic epithelia, as well as natural killer cells, myelinated nerves and cells from APUD systems. The expression of HNK-1 antigen on prostate cancer was investigated immunohistochemically by avidinbiotin-peroxidase complex (ABC) method with anti-HNK-1 MAb to clarify the relationship between anti-HNK-1 immunostaining of the cancerous tissue and the tumor differentiation, and that between the former and the survival rate of patients. Of 52 patients with prostate cancer, 49 were reactive with anti-HNK-1 MAb, the positive rate being 94%. The well differentiated cancer showed the highest percentage of positive cancer cells and the strongest staining, while the poorly differentiated cancer had the lowest percentage of positive cancer cells and the weakest staining. HNK-1 antigen was highly expressed on prostate cancer, and the better differentiated the cancer, the more HNK-1 antigen expressed. We also analyzed the total 5-year survival rate of the 52 patients, and the average 5-year survival rate and non-progression rate of 32 patients in stage D2 who had received only endocrinotherapy. Significantly higher survival rate and non-progression rate were observed in the group with more than two-thirds positive cancer cells as compared with the group with less than two-thirds positive cancer cells. The results suggest that the expression of HNK-1 antigen on prostate cancer may be a useful prognostic factor for patients with prostate cancer.
