摘要

Aim: To evaluate the best individualized prostate biopsy strategies for Chinese patients with suspected prostate cancer. Methods: The present study included 221 Chinese patients who underwent transrectal ultrasound guided prostate biopsies for the first time. All patients underwent the same 10-core biopsy protocol. In addition to the Hodge sextant technique, four more biopsies were obtained from the base and middle regions of bilateral peripheral zones.The differences between 10-core and sextant strategies in cancer detection among patients with different prostate specific anitgen (PSA) levels were evaluated. The relationship between PSA level, number of positive biopsy cores and organ-confined cancer rate in prostate cancer patients was also analyzed. Results: The overall prostate cancer detection rate was 40.7% in the 221 patients. The 10-core strategy increased cancer detection by 6.67% (6/90) in our patients (P < 0.05). The increased cancer detection rates decreased significantly when the patient PSA level increased from 0-20 ng/mL to 20.1-50 ng/mL and > 50 ng/mL (P < 0.01). The number of positive biopsy cores in prostate cancer patients increased significantly with increasing patient PSA level (P < 0.01). The rate of organ-confined prostate cancer decreased significantly with increasing patient PSA level (P < 0.01). Conclusion: The extended 10-core strategy is recommended for Chinese patients with PSA < 20 ng/mL and the sextant strategy is recommended for those with PSA > 50 ng/mL. For patients with PSA ranging from 20.1 ng/mL to 50 ng/mL, the 10-core strategy should be applied in patients with life expectancy > 10 years and the sextant strategy should be applied in those with life expectancy < 10 years.
