Biochemical failure after radical prostatectomy in intermediate-risk group men increases with the number of risk factors

چکیده
INTRODUCTION We aimed to determine whether the number and type of risk factors are associated with biochemical recurrence-free survival after radical prostatectomy in men with D'Amico intermediate-risk prostate cancer. MATERIALS AND METHODS Between August 1998 and May 2013, 481 Japanese patients underwent antegrade radical prostatectomy. The relationships between the rate of PSA failure after radical prostatectomy and the number and type of risk factors were examined in the intermediate-risk group. RESULTS According to the D'Amico criteria, the low-, intermediate-, and high-risk groups comprised 107, 222, and 152 patients, respectively. The median follow-up period after surgery was 54.1 months. The 5-year PSA failure-free rates in the low-, intermediate-, and high-risk groups were 96.5%, 88.9%, and 72.6%, respectively (P < 0.001). The 5-year PSA failure-free rate in the intermediate-risk group with one, two, and three intermediate risk factors was 94.9%, 88.4%, and 49.0%, respectively (P < 0.001). The difference between the high- and intermediate-risk group with three intermediate risk factors was statistically significant based on the log-rank test (P = 0.039). CONCLUSION The number of intermediate risk factors is significantly associated with the PSA failure-free survival rate after radical prostatectomy in the intermediate-risk group. Patients classified into the intermediate-risk group based on all three intermediate risk factors are less likely to achieve a complete cure through surgery alone.

Outcome of radical prostatectomy in primary circulating prostate cell negative prostate cancer
INTRODUCTION Around 90% of prostate cancers detected using the serum prostate specific antigen (PSA) as a screening test are considered to be localised. However, 20-30% of men treated by radical prostatectomy experience biochemical failure within two years of treatment. The presence of primary circulating prostate cells (CPCs) in the blood of these men implies a dissemination of the tumour and ...

متن کاملClinical utility of percent prostate needle biopsy tissue with cancer cutpoints to risk stratify patients before radical prostatectomy.
OBJECTIVES The percentage of total prostate needle biopsy tissue with cancer was previously found to be a stronger predictor of biochemical failure after radical prostatectomy (RP) than either biopsy Gleason score or serum prostate-specific antigen (PSA). To improve our ability to predict preoperatively the risk of biochemical recurrence after RP, we sought to determine the cutpoints of the per...

Purpose: To determine the clinical utility of the percentage of positive prostate biopsies in predicting prostate-specific antigen (PSA) outcome after radical prostatectomy (RP) for men with PSA-detected or clinically palpable prostate cancer. Methods: A Cox regression multivariable analysis was used to determine whether the percentage of positive prostate biopsies provided clinically relevant ...
