Background and Objectives
Minimally invasive methods are expected to avoid the risk of overtreatment and overtreatment of radical therapy to manage the increased number of patients with low-volume, low-grade localized prostate cancer. Based on our experience of radical transurethral resection of prostate cancer (TURPCa) as a radical treatment, we studied the efficacy and safety of focal TURPCa as a focal therapy for patients with localized prostate cancer.

Materials and Methods
We performed focal TURPCa in 49 patients during the period from July 2007 to August 2016 and followed them with prostate-specific antigen (PSA) testing for the mean period of 68.0 months. We selected the patient as a candidate for the study if the biopsy revealed that cancer foci were limited in one lobe, or the foci were several or less even found in both lobes. Standard TURP was followed by further resection and fulguration of the peripheral zone where cancer was considered to exist. We selected one of our three methods of focal TURPCa as follows: one lobe radical TURPCa, radical resection of the affected lobe with unaffected lobe being resected less vigorously; nerve-sparing radical TURPCa, radical resection of both lobes except for the posterolateral part of the prostate; target radical TURPCa, radical resection of the cancer focus and the surrounding prostate when the target is suggested single.

Twelve patients were in the low-risk group (D’Amico), 29 in the intermediate-risk group, and 8 in the high-risk group. Pathological stages were as follows: pT0, three cases; pT2a-b, 17 cases; pT2c, 29 cases. The preoperative PSA of 6.15±2.73 ng/mL (mean±SD) dropped to 0.172±0.283 ng/mL postoperatively. PSA failure occurred in only two patients (4.1%). Incontinence did not develop and erectile function was preserved in eight (44.4%) of the 18 potent patients. The most frequent complication was bladder neck contracture (20.4%). Other complications included acute epididymitis (8.1%), bladder tamponade (2.0%). No patients died of prostate cancer.

Though the final assessment of efficacy will require long-term follow-up results with more cases, we may think focal TURPCa can be another treatment option as a focal therapy for localized prostate cancer.
