Are men who undergo radical prostatectomy with lower urinary tract symptoms at an increased risk for aggressive prostate cancer?
OBJECTIVE
We aimed to determine whether prediagnostic lower urinary tract symptoms (LUTS) are associated with the aggressiveness of nonmetastatic prostate cancer (PCa) and compared the clinicopathologic features of PCa patients with and without preexisting LUTS.


METHODS
We retrospectively reviewed the medical records of 295 prostate cancer patients who underwent a radical prostatectomy (RP) by a single surgeon from 2006 to 2010. A total of 205 patients were assigned to two groups according to whether they showed preoperative LUTS (International Prostate Symptom Score [IPSS]≥8). Clinical, operative, pathologic, and postoperative functional data were collected.


RESULTS
The mean age at RP was 62.7 years in the no LUTS group (group A, n=108) and 64.7 in the LUTS group (group B, n=97). The baseline mean IPSS score was 6.1 in group A and 14.6 in group B (p=0.029). The incidence of pathologic T3a stage or above was significantly higher in group B than in group A (p=0.036). The mean postoperative follow-up period was 16.8 months (range, 4 to 38 months). The mean time to biochemical recurrence was 16.9 and 18.2 months in groups A and B, respectively (p=0.148). The median time to recovery of urinary incontinence was 3.6 and 3.3 months in groups A and B, respectively.


CONCLUSIONS
PCa patients without baseline LUTS had a favorable result of pathologic T stage even though there were no significant differences in biochemical recurrence or recovery of postoperative incontinence compared with patients with baseline LUTS.
