[On extended biopsy of the prostatic gland].
The aim of our trial was to investigate correlation between the size of the prostate and probability of cancer detection with transperineal biopsy. Transperineal 12-sample biopsy of the prostate was made in 203 men aged 48-58 years (mean age 68.0 +/- 8.6 years) suspected of having prostatic cancer (PC). Total detection of cancer was 33.5%. PC patients had higher levels of PSA, more frequent alterations at rectal palpation and transrectal ultrasound investigation, while mean size of the prostate was the same in cancer and cancer-free patients. Differences in PC detection rate in patients with different sizes of the prostate were statistically insignificant. Use of sextant biopsy could not detect PC in 15 males (22.1%) cases. Thus, there is no correlation between the size of the prostatic gland and diagnostic value of transperineal biopsy obtaining 12 tissue samples. The above data do not support the necessity of extended biopsy in patients with large prostate.
