Management and Oncologic Outcomes of Incidental Prostate Cancer After Transurethral Resection of the Prostate in Denmark.

We observed high prostate cancer mortality after TURP with GG1 or GG2, likely due to unsampled high-grade cancer in the peripheral zone. Patients with incidental prostate cancer should be further investigated to rule out high-grade cancer. For patients with GG1 on TURP, once a subsequent biopsy does not show cancer, follow-up should be lessened similar to that of patients with an initial nonmalignant biopsy.
