The diagnostic value of prostate cancer between holmium laser enucleation of the prostate and transurethral resection of the prostate for benign prostatic hyperplasia: A retrospective comparative study.

To compare the diagnostic value of prostate cancer (PCa) between holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP).

We retrospectively analyzed the clinical data of 2909 patients who underwent surgery for benign prostatic hyperplasia (BPH) from January 2008 to June 2018. A total of 1362 patients received HoLEP, and 1547 patients received TURP. The baseline patient characteristics were collected. We then compared the perioperative outcomes of these patients who diagnosed with incidentally diagnosed prostatic carcinoma (IDPC) or PCa after BPH surgeries.

The total detection rate of PCa in HoLEP group was higher than that in TURP group (85/6.24% vs. 61/3.94%, p = 0.005). Specifically, 55(4.6%) patients were diagnosed with IDPC in HoLEP group with prostate-specific antigen (PSA) less than 4 ng/ml, and 37(2.7%) patients in TURP group (p = 0.014). For the patients with PSA between 4 and 10 ng/ml, 15(13.9%) patients were diagnosed with PCa after HoLEP, and 6(5.0%) patients after TURP (p = 0.023). But the detection rate of PCa was not significantly different between the two groups when PSA was over 10 ng/ml. On the other hand, 57 in 1215 patients with no prostate biopsy preoperatively were diagnosed with PCa after HoLEP, while 42 in 1370 patients after TURP (4.7% vs. 3.1%, p = 0.040), respectively. Twenty-six patients received once biopsy and diagnosed with PCa in HoLEP group, while 15 patients in TURP group (18.4% vs. 8.9%, p = 0.018), respectively. However, no significant difference was observed for patients who received twice prostate biopsy in the two groups.

The present study showed that HoLEP can provide a higher total detection rate of PCa when compared with TURP. Besides, this superiority was especially embodied in patients with PSA less than 10 ng/ml.
