OBJECTIVES: To investigate who needs a careful postoperative monitoring for prostate cancer (PCa) after holmium laser enucleation of the prostate (HoLEP). We examined characteristics and oncological outcomes of HoLEP-related PCa.
METHODS: Patients who underwent HoLEP during 2002-2017 in a Japanese tertiary center were retrospectively analyzed. Patients were divided into non-PCa, PCa with HoLEP specimen (PCa-Ope), and PCa diagnosed during follow-up (PCa-Post). Outcomes of all HoLEP-related PCa were monitored.
RESULTS: Of the total 758, 60 (7.9%) were diagnosed with PCa from resected specimen of HoLEP and 9 (1.2%) were diagnosed postoperatively. Preoperative prostate-specific antigen (iPSA), postoperative PSA (pPSA), and PSA density were significantly higher in both PCa groups than those in non-PCa group. While iPSA significantly correlated to prostate volume (PV), pPSA was not associated with PV. A receiver-operating-characteristics curve demonstrated that pPSA 1.2 ng/mL achieved the optimal cut-off (AUC 0.95) for the incidence of PCa-Post. In addition to the incidence of PCa and iPSA, lower enucleation efficiency (enucleated volume /PV) was significantly associated with pPSA >1.2 ng/mL. Among PCa-Ope, 51 were Grade Group (GG) ≤2 and 42 were followed-up with active surveillance, whereas 8 of 9 PCa-Post were GG ≥3 and 2 progressed to death.
CONCLUSIONS: Patients undergoing HoLEP are associated with some risk of potential PCa. While oncological outcomes were favorable among PCa-Ope, postoperative PSA should be carefully monitored even if not diagnosed with PCa with HoLEP specimen. Enucleation efficiency should be also considered not to misread pPSA value.
