The predictive value of aspiration and trepan biopsy is analysed in 247 cases of prostatic cancer. The diagnostic value of trepan biopsy is 90.1%; it is not determined by the degree of tumor differentiation. The value of aspiration biopsy varies with different degree of differentiation; it is 42.1% for well-differentiated cancer, 81.2%--for moderately- and 97.4%--for poorly-differentiated tumors. Aspiration biopsy is a safe procedure, while trepan biopsy may be followed by severe complications.
