Abstract
Objective. To determine a possible role for HistoScanning technique in surveillance for patients who underwent HIFU-ablation for prostate cancer. Material and methods. Eighty patients who underwent transurethral resection and HIFU-ablation in university clinic with different follow-up duration (range: 36 - 84 months; median - 52 months) were included in this study. All patients underwent prostate specific antigen (PSA) testing, transrectal ultrasound examination and HistoScanning of residual prostatic tissue during follow-up. Results. Overall, 72 patients of 80 had suspicious lesions on HistoScanning during post-HIFU surveillance. Eleven patients had VHS value, which is the sum of volume of suspicious lesions, exceeding 1 cm3; 10 patients experienced biochemical relapse by Stuttgart definition (90.9%). Significant predictors of biochemical relapse were PSA nadir over 1.0 ng/ml (hazard ratio [HR]: 3.1; confidence interval [CI]: 1.7 - 3.5) and VHS / Vres. ratio over 0.5 (HR: 4.9; CI: 3.9 - 5.5). Ten patients reached VHS / Vres. threshold value (> 0.5) > 3 months before meeting criteria for Stuttgart biochemical failure. Conclusion. HistoScanning may prove useful for surveillance for patients who underwent HIFU-ablation for prostate cancer, but it still requires further standardization and validation in this setting.
