National Journal of Andrology 2014;20(12):1136-1140
Most prostate cancer cases ultimately relapse after a period of initial response to castration therapy and progress to intractable castration-resistant prostate cancer (CRPC). Hardly any therapeutic options currently used can improve the 2- to 3-year survival of the patient. Recently, some new drugs for the treatment of CRPC through various action mechanisms have been approved, and others are in the advanced stage of clinical trial. This review provides an overview of these new therapeutic agents.

Despite the wide application of prostate-specific antigen-based screening leading to a profound stage migration in prostate cancer (PC), a significant percentage of men are still being diagnosed with clinically high-risk disease that requires aggressive treatment. Optimal management in these patients remains challenging, and strong advocates for radical prostatectomy (RP), radiotherapy, androgen deprivation therapy, and, increasingly, a multimodal approach abound. Currently, surgery for high-risk PC is frequently applied. RP offers an attractive opportunity for tumor excision either as a definitive management or as a first step in multimodal therapy. Nevertheless, this approach is still controversial. In this review, we discuss the current evidence for the role of RP in this clinical setting, including surgical considerations and outcomes. The role of robot-assisted RP, which is increasingly utilized in Korea in this clinical scenario, is discussed.

OBJECTIVETo explore the effectiveness and significance of whether electrical acupuncture stimulation combining with pelvic floor muscle therapy (PFMT) can improve the recovery of urinary continence.
METHODSA total of 109 patients took part in the study of novel combination treatment for urinary continence from September 2008 to September 2009. Patients were divided into study group (n = 40) and control group (n = 69). The patients in study group received electrical acupuncture stimulation therapy combined with PFMT one week after removal the catheter. The patients in control group performed PFMT as the only treatment for post prostatectomy incontinence. The patients were followed up closely, with their clinical characteristics recorded, questionnaires of ICI-Q-SF filled up, and all the data for statistical analysis collected.
RESULTSThere was a significant difference between the study group and the control group in the urinary control curve (P = 0.029). The difference of continence probability between these two groups became greater from 4 weeks after surgery, and the difference reached the peak at 6 weeks (P = 0.023). Then the difference became smaller, and there was no difference at 16 weeks after surgery. ICI-Q-SF questionnaires showed the same results.
CONCLUSIONElectrical acupuncture stimulation therapy combining with PFMT can improve the recovery of patients' urinary continence after radical prostatectomy.

PURPOSE: To evaluate the oncologic outcomes between adjuvant radiotherapy (ART) and salvage radiotherapy (SRT) in patients with locally advanced prostate cancer or with adverse pathologic factors including positive surgical margin and high Gleason score. MATERIALS AND METHODS: We searched the literature published from January 2000 until December 2014 at MEDLINE, PubMed, Web of Science, Embase, ProQuest, and Cochrane Library. To be specific, included were studies comparing ART and SRT settings if they followed up oncologic outcomes more than 5 years. RESULTS: Overall, 3 retrospective, nonrandomized, observational studies, 1 matched control analysis, and 3 prospective randomized controlled studies met our inclusion criteria including a total of 2,380 patients (1,192 ART vs. 1,188 SRT). Higher favorable results were found in ART than in SRT was seen in the 5-year and 10-year biochemical recurrence (BCR)-free survival (risk ratio [RR], 0.61 and 0.70; 95% confidence interval [CI], 0.54-0.69 and 0.63-0.76). ART had a significantly higher 5-year progression-free survival rate than that in SRT (RR, 0.64; 95% CI, 0.51-0.80), but this was not the same for the 10-year progression-free survival rate (RR, 0.88; 95% CI, 0.72-1.08). There was no significant difference for the 5-year and 10-year overall survival rates between ART and SRT (RR, 0.80 and 0.94; 95% CI, 0.59-1.07 and 0.80-1.11). CONCLUSIONS: ART showed favorable results in BCR-free survival during the 5-year follow-up period. However, the 10-year progression-free survival and overall survival did not show any difference between ART and SRT.

6.Tadalafil rehabilitation therapy for erectile dysfunction following prostatectomy.
National Journal of Andrology 2012;18(10):953-956
Radical prostatectomy (RP) is preferred for many patients with clinically localized prostate cancer. Despite the introduction of the nerve sparing technique and progressive modifications on RP, postoperative preservation of penile erectile function remains a challenge to urologists. Earlier initiation of penile rehabilitation can significantly improve the patient's quality of life affected by erectile dysfunction (ED) following RP. Tadalafil, a long-acting PDE5 inhibitor with a unique clinical profile, has proved effective in penile rehabilitation in the treatment of RP-associated ED in both clinical trails and animal models. This article reviews current strategies for the management of ED after RP and evaluates the efficacy and safety of tadalafil in post-RP penile rehabilitation.

7.Current Status of Cryotherapy for Prostate and Kidney Cancer.
Korean Journal of Urology 2014;55(12):780-788
In terms of treating diseases, minimally invasive treatment has become a key element in reducing perioperative complications. Among the various minimally invasive treatments, cryotherapy is often used in urology to treat various types of cancers, especially prostate cancer and renal cancer. In prostate cancer, the increased incidence of low-risk, localized prostate cancer has made minimally invasive treatment modalities an attractive option. Focal cryotherapy for localized unilateral disease offers the added benefit of minimal morbidities. In renal cancer, owing to the increasing utilization of cross-sectional imaging, nearly 70% of newly detected renal masses are stage T1a, making them more susceptible to minimally invasive nephron-sparing therapies including laparoscopic and robotic partial nephrectomy and ablative therapies. This article reviews the various outcomes of cryotherapy compared with other treatments and the possible uses of cryotherapy in surgery.

PURPOSE: The purpose of this study was to evaluate whether neo-adjuvant hormonal therapy (NHT) prior to radical retropubic prostatectomy (RRP) for prostate cancer (PCa) is beneficial in terms of surgical outcomes and for preventing or delaying biochemical recurrence via single-surgeon case series study. MATERIALS AND METHODS: Fifty-three men underwent RRP by a single surgeon. The patients were divided into two groups according to whether or not NHT was performed prior to RRP. The study was analyzed retrospectively. We evaluated clinical parameters, surgical parameters, and biochemical recurrence rate. Group 1 (n=34) was treated with RRP only, while Group 2 (n=19) underwent RRP along with NHT. RESULTS: There were no significant differences in clinical, operation-related and pathological factors between the two groups (p>0.05). There was also no significant difference in biochemical recurrence rate between the two groups at the last follow-up, although Group 2 tended to have a lower PCa recurrence rate than Group 1 and the initial prostate-specific antigen (PSA) level was significantly higher in Group 2 than Group 1 (p=0.0496). CONCLUSION: The present single-surgeon case series study revealed a trend toward a lower rate of PCa recurrence in NHT+RRP treated patients compared to those treated with RRP alone, but this did not reach statistical significance, despite the fact that NHT+RRP patients exhibited higher serum PSA levels preoperatively. Prospective studies with a longer duration of observation and a greater number of patients would be helpful in evaluating NHT more definitively.

Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). However, whether the PFME guided by a therapist (G-PFME) can contribute to the recovery of urinary continence for patients after RP is still controversial. We performed this meta-analysis to investigate the effectiveness of G-PFME on UI after RP and to explore whether the additional preoperative G-PFME is superior to postoperative G-PFME alone. Literature search was conducted on Cochrane Library, Embase, Web of Science, and PubMed, to obtain all relevant randomized controlled trials published before March 1, 2018. Outcome data were pooled and analyzed with Review Manager 5.3 to compare the continence rates of G-PFME with control and to compare additional preoperative G-PFME with postoperative G-PFME. Twenty-two articles with 2647 patients were included. The continence rates of G-PFME were all superior to control at different follow-up time points, with the odds ratio (OR) (95% confidence interval [CI]) of 2.79 (1.53-5.07), 2.80 (1.87-4.19), 2.93 (1.19-7.22), 4.11 (2.24-7.55), and 2.41 (1.33-4.36) at 1 month, 3 months, 4 months, 6 months, and 12 months after surgery, respectively. However, there was no difference between additional preoperative G-PFME and postoperative G-PFME, with the OR (95% CI) of 1.70 (0.56-5.11) and 1.35 (0.41-4.40) at 1 month and 3 months after RP, respectively. G-PFME could improve the recovery of urinary continence at both early and long-term stages. Starting the PFME preoperatively might not produce extra benefits for patients at early stage, compared with postoperative PFME.

OBJECTIVETo understand long-term survival rate after combined androgen blockade (CAB) in patients with advanced prostate cancer.
METHODSA selected population of 59 patients with advanced prostate cancer were treated with CAB. 28.81% (17/59) of patients had clinical locally advanced disease (stage T3-4N0M0), and 45.76% (27/59) of patients had metastatic disease (stage TxNxM+). Overall, patients were followed for a median of 62 (range 6-136) months.
RESULTSOf the 59 patients with advanced prostate cancer, 3-year, 5-year and 7-year overall survival rates were 79.36%, 61.46% and 49.15%, respectively. The 5-year survival rate were 80.77% and 32.65% for clinical locally advanced disease and metastatic disease. Specifically, men with poorly differentiated prostate cancer had a 5-year survival of only 30% when compared with men with well-differentiated prostate disease who had a 5-year survival of 86.21%.
CONCLUSIONBased on these findings, men with poorly differentiated cancer, stage T3c-4NxMx or TxNxM+ and PSA level above 30 microg/L had a high probability of dying from their advanced prostate cancer.
