Abstract:
PURPOSE: We retrospectively investigated the changes of prostate cancer detection rate according to patients prostate volume, age with prostate-specific antigen (PSA) levels of above 4.0ng/ml. MATERIAL AND METHODS: Data were collected from 663 patients who underwent 10 core prostate biopsy for elevated PSA above 4.0ng/ml. The biopsy-proven cancer patient group was compared to the non-cancer patient group according to age, PSA, prostate volume and PSAD. Prostate cancer detection rate was calculated according to prostate volume (less than 40 vs 40 or more 40ml) and age (less than 60, 60-69, 70-79, 80 or more years old). Also we compared prostate cancer detection rate according to PSA levels (4-10 vs 10-20ng/ml). RESULTS: Among the 663 patients who underwent prostate biopsy, prostate cancer was detected in 134 patients (20.2%). There were no stastically difference in mean age, mean prostate volume, and mean PSAD except mean PSA (13.9 vs 11.9ng/ml) between cancer and non-cancer groups. The cancer detection rate in small prostate was significantly higher than large prostate (23.5% vs 16.0%). The cancer detection rate was significantly increased with age: from 14.5% for below 60 year-old patients to 30.3% for the 80 or more year-old patients. There was no significant difference in cancer detection rate between the two PSA groups (19.0 vs 20.5%). CONCLUSION: Prostate cancer detection rate was higher in old patients and patients with small prostate volume. The older age group and the patients with small prostate volume was considered as the important factors to decide whether biopsy of prostate is needed.
