We investigated the tissue concentration of sialic acid and fibronecti
n in patients with prostatic cancer. The mean sialic acid and fibronec
tin levels in patients with prostatic cancer were 19.02 +/- 6.30 mu g/
mg protein and 20.22 +/- 7.13 mu g/mg protein, respectively versus 13.
01 +/- 4.53 mu g/mg protein and 11.77 +/- 6.74 mu g/mg protein for nor
mal prostatic tissues. Sialic acid and fibronectin levels in cancerous
patients were significantly higher than in the control group (P < 0.0
5).
