Objective:
This study was conducted to research the factors determining biochemical recurrence (BCR) in low-risk localized prostate cancer patients who underwent radical prostatectomy (RP).
Materials And Methods:
We retrospectively analyzed the data of 504 patients who had undergone RP between 2003 and 2013 at our clinic. One hundred and fifty-two patients who underwent RP for low-risk prostate cancer were included in the study.
Results:
The mean follow-up period for patients was 58.7 (21-229) months. The mean age of the patients was 63.7±7.2 years (49-79). The mean prostate specific antigen (PSA) value was 5.25±4.22 ng/mL (3.58-9.45). The BCR rate after the operation was 25% (38/152). In the univariate analysis, recurrence determining factors were shown to include extracapsular involvement (ECI) (p=0.004), capsular invasion (CI) (p=0.001), age (p=0.014), and tumor size (p=0.006). However, only CI was found to be significant in multivariate analysis (p=0.001).
Conclusion:
Capsular invasion is an independent risk factor in low-risk prostate cancer patients who underwent RP for BCR.
