Tissue fibronectin levels of human prostatic cancer, as a tumor marker.

In this study, tissue fibronectin levels have been assayed in human prostatic cancer, benign prostatic hyperplasia and normal prostatic tissue. The mean tissue fibronectin levels for prostatic cancer, benign prostatic hyperplasia and normal groups were found to be 20.22 +/- 8.66 micrograms/mg protein and 11.77 +/- 6.74 micrograms/mg protein, respectively. In the malignant group, the mean fibronectin concentrations, appeared to be significantly higher than normal, (p < 0.05). On the other hand, fibronectin levels of benign prostatic hyperplasia were found to be statistically insignificant in comparison to the normal group (p > 0.05).
