PURPOSE: Holmium laser enucleation of the prostate (HoLEP) has become a popular alternative to TURP for desobstructive prostate surgery. The prevalence of incidental prostate cancer (iPCa) during surgery varies depending on many preoperative factors. To evaluate whether the surgical procedure itself (HoLEP vs. TURP) influences iPCa detection, we performed a case-by-case matched-pair analysis.
METHODS: Preoperative patient age, total PSA, and prostate volume were used as matching criteria. Descriptive statistics were used to confirm matching quality. Parameters were analyzed by Fisher's exact test and T test or Mann-Whitney U test for dichotomous and continuous variables, respectively. Uni- and multivariate logistic regression analyses were performed to identify predictors for iPCa detection.
RESULTS: 60 out of 136 patients after HoLEP and 60 out of 1220 patients after bipolar TURP (bTURP) could be included. Mean patient age was 71.5 and 70.3 years in the HoLEP and bTURP group, respectively. Median preoperative total PSA was 4.42 ng/ml for HoLEP and 4.33 ng/ml for bTURP patients. Median preoperative prostate volume was 75.0 cc in both groups. Mean percentage of tissue removed by HoLEP and bTURP was 63.5 and 49.5% (p < 0.001), respectively. IPCa was found in 23.3% of HoLEP specimens compared to 8.3% in bTURP (p = 0.043). PSA density was the only independent predictor for iPCa detection.
CONCLUSIONS: In this first matched-pair analysis, HoLEP provides a significantly higher iPCa detection rate than bTURP. This might be a result of a more efficient tissue removal during HoLEP. PSA density was the only independent risk factor for iPCa.
