[A Case of Effective Endovascular Treatment for Recurrent Bleeding from Advanced Breast Cancer].

A-58-year-old woman was diagnosed with breast cancer 8 years ago at another hospital, but refused surgical treatment. From 2 years ago, her skin invasion of cancer lesions began bleeding. The patient required frequent blood transfusions due to anemia associated with repeated bleeding. She was referred to our department for local treatment and palliative care. Diagnostic imaging revealed multiple lung, bone and liver metastasis. The patient refused to receive systemic chemotherapy, and she was recommended radiation therapy for repeated massive bleeding, but her consent was not obtained. She agreed to receive arterial embolization from the tumor-bearing vessels plus intravenous anti-cancer drug therapy. The hemostatic effect was observed for 4 to 5 weeks per treatment, and tumor reduction was also observed. She received a total of 6 treatments during 8 months until her death. These treatments were effective in maintaining quality of life at the end of life.

Relationship between frailty and lower urinary tract symptoms among community-dwelling adults.

OBJECTIVES: To evaluate the relationship between frailty and lower urinary tract symptoms (LUTS), the association of frailty and LUTS remains unclear. METHODS: This cross-sectional study investigated LUTS and frailty in 710 individuals (249 men and 461 women, aged ≥60 years) who participated in the Iwaki Health Promotion Project between 2014 and 2015 in Hirosaki, Japan. Parameters of frailty were compared for individuals with mild and moderate to severe symptoms of LUTS. The International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS) were used to evaluate LUTS. Frailty was evaluated by the frailty phenotype (FP), modified frailty index (mFI), and frailty discriminant score (FDS). The influence of frailty on LUTS was investigated by multivariate logistic regression analyses. RESULTS: Frailty parameters of age, renal function, and lower physical activity were significantly associated with severity of IPSS and OABSS. FP and mFI were significantly associated with severity of OABSS and IPSS, respectively. The FDS was significantly associated with severity of IPSS and OABSS. FP, mFI, and FDS were significantly associated with severity of nocturia. Multivariate logistic regression analyses revealed that FDS was independently associated with the severity of IPSS, OABSS, and nocturia, whereas FP and mFI were significantly associated with the severity of nocturia alone. CONCLUSIONS: Individuals with LUTS are potentially frailer than those without LUTS. Although the influence of frailty on LUTS is different depending on the measurement tool, attention for frailty is necessary for subjects with LUTS.

Serum N-glycan profiling is a potential biomarker for castration-resistant prostate cancer.

We investigated the diagnostic and prognostic potential of serum N-glycan profiling for castration-resistant prostate cancer (CRPC). We retrospectively investigated serum N-glycan structural analysis by glycoblotting for 287 patients with benign prostatic hyperplasia (BPH), 289 patients with newly diagnosed prostate cancer (PC), 57 patients with PC treated with androgen-deprivation therapy without disease progression (PC-ADT), and 60 patients with CRPC. N-Glycan profiling was compared between the non-CRPC (BPH, newly diagnosed PC and PC-ADT) and CRPC patients. We obtained the quantitative score for CRPC (CRPC N-glycan score) by discriminant analysis based on the combination of 9 N-glycans that were significantly associated with CRPC. The median CRPC N-glycan score was found to be significantly greater in CRPC patients than in non-CRPC patients. The CRPC N-glycan score could classify CRPC patients with sensitivity, specificity, and area under the curve of 87%, 69%, and 0.88, respectively. The CRPC N-glycan score >1.7 points was significantly associated with poor prognosis in patients with CRPC. The glycoprotein analysis showed that not immunoglobulins but α-1-acid glycoprotein (AGP) were a potential candidate for the carrier protein of N-glycans. The overexpression of specific N-glycans may be associated with their castration-resistant status and be a potential biomarker for CRPC.

Relationship between oxidative stress and lower urinary tract symptoms: results from a community health survey in Japan.

OBJECTIVE: To investigate the relationship between oxidative stress and lower urinary tract symptoms (LUTS) in a community-dwelling population. MATERIALS AND METHODS: The cross-sectional study included 1 113 people who participated in the Iwaki Health Promotion Project of 2015 in Hirosaki, Japan. LUTS were assessed using structured questionnaires, including the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS). IPSS > 7, OABSS > 5, nocturia score > 1, or urge incontinence score > 1 were defined as moderate to severe symptoms. 8-Hydroxy-2'-deoxyguanosine (8-OHdG) and advanced glycation end products (AGEs) were measured by urine analysis and skin autofluorescence, respectively. The relationship between oxidative stress and LUTS was investigated using logistic regression analyses. RESULTS: This study included 431 men and 682 women. AGEs and 8-OHdG levels were significantly higher in severe forms of LUTS. Multivariate logistic regression analyses showed that AGE levels were significantly associated with a higher frequency of nocturia but were not associated with IPSS, OABSS or urge incontinence. No significant association was observed between LUTS and 8-OHdG levels. CONCLUSIONS: We observed a significant association between AGE levels and nocturia score > 1. Further research is necessary to clarify a possible causal relationship between oxidative stress and nocturia.

Clinical implication of a quantitative frailty assessment tool for prognosis in patients with urological cancers.

OBJECTIVES: Optimal tools for evaluating frailty among urological cancer patients remain unclear. We aimed to develop a quantitative frailty assessment tool comparing healthy individuals and urological cancer patients, and investigate the clinical implication of quantitative frailty on prognosis in urological cancer patients. RESULTS: Gait speed, hemoglobin, serum albumin, exhaustion, and depression were significantly worse in patients with all types of cancers than in pair-matched controls. Frailty discriminant score (FDS) showed clear separation between controls and urological cancer patients, and significant association with the Fried criteria. Overall survivals were significantly shorter in patients with a higher score (>2.30) than in those with a lower score among nonprostate cancer (bladder, upper tract urothelial carcinoma, and renal cell carcinoma) patients. In prostate cancer patients, overall survivals were significantly shorter in patients with a higher score (>3.30) than in those with a lower score. CONCLUSIONS: FDS was significantly associated with frailty and prognosis in urological cancer patients. This tool for frailty assessment can help patients and physicians make more informed decisions. Further validation study is needed. MATERIALS AND METHODS: Total 605 urological cancer patients presenting to our hospital underwent a prospective frailty assessment. Controls were selected from 2280 community-dwelling subjects. Frailty was assessed via physical status, blood biochemical tests, and mental status. We compared frailty variables between pair-matched controls and urological cancer patients. We developed FDS using frailty variables, and compared with the Fried criteria. The influence of FDS on overall survivals was investigated by Kaplan-Meier analysis and Cox regression analysis.

A Case of Fibrous Pseudotumor in the Scrotum: Challenge for Diagnosis and Testicular Preservation.

A paratesticular fibrous pseudotumor is a relatively rare benign disease. Preoperatively diagnosing a fibrous pseudotumor is challenging because distinguishing these masses from malignant tumors on the basis of clinical and radiological findings can be difficult. We present a case of a 28-year-old man who presented with a painless palpable mass in the right scrotum; the fibrous pseudotumor of the tunica vaginalis was treated with organ-sparing surgery. Computed tomography and magnetic resonance imaging revealed paratesticular tumors. Testicular tumor marker levels were within normal limits. We scheduled the patient to undergo tumor biopsy combined with intraoperative rapid diagnosis. Frozen section assessment suggested a fibrous pseudotumor without malignancy. We successfully performed organ-sparing surgery. Testicular-sparing surgery combined with frozen section assessment is primarily used for treating paratesticular fibrous pseudotumors.

Opacity of big toenail predicts poor prognosis in patients with end-stage renal disease on hemodialysis.

BACKGROUND: The impact of nail abnormalities on prognosis in hemodialysis patients is unknown. This study investigated whether toenail opacity as a readout of nail abnormalities predicted prognosis in hemodialysis patients. METHODS: In this observational study, 494 eligible hemodialysis patients who received hemodialysis at Oyokyo Kidney Research Institute between September 2010 and December 2015 were included. The presence of nail abnormalities was objectively evaluated by big toenail opacity ratio measurement. Primary endpoint was overall survival, and secondary endpoints were lower limb amputation and determination of risk factors for poor prognosis among patient demographics, comorbidities, blood tests, and big toenail opacity. Overall survival and lower limb survival were evaluated using the Kaplan-Meier method with log-rank test. Multivariate Cox regression analyses assessed predictors for poor prognosis. RESULTS: Big toenail opacity was found in 259 (52%) patients. Patients with big toenail opacity were significantly older, had shorter duration of dialysis, higher prevalence rates of diabetes mellitus (DM), cardiovascular disease (CVD), and higher mortality rates than those without opacity. Presence of big toenail opacity predicted poor prognosis for both overall and lower limb survival. Multivariate Cox regression analyses revealed serum albumin, the presence of DM and big toenail opacity were independent risk factors for both poor overall and lower limb survivals. CONCLUSION: The prevalence of big toenail opacity was high in hemodialysis patients. Despite the short observation period, our findings indicated that big toenail opacity had significant predictive power for poor overall and lower limb survival.

Cost-effectiveness comparison between neoadjuvant chemohormonal therapy and extended pelvic lymph node dissection in high-risk prostate cancer patients treated with radical prostatectomy: a multi-institutional analysis.

The aim of the present study was to assess the cost-effectiveness of extended pelvic lymph node dissection (ePLND) compared to neoadjuvant chemohormonal therapy using gonadotropin-releasing hormone agonist/antagonist and estramustine. We retrospectively analyzed data within Michinoku Urological Cancer Study Group database containing 2971 PC patients treated with radical prostatectomy (RP) at four institutes between July 1996 and July 2017. We identified 237 and 403 high-risk patients who underwent RP and ePLND (ePLND group), and neoadjuvant chemohormonal therapy followed by RP and limited PLND (neoadjuvant group), respectively. The oncological outcomes and cost-effectiveness were compared between groups. Medical cost calculation focused on PC-related medication and adjuvant radiotherapy. Biochemical recurrence-free and overall survival rates in the neoadjuvant group were significantly higher than those in the ePLND group. Significantly higher number of patients progressed to castration-resistant PC in the ePLND group than in the neoadjuvant group. Background-adjusted multivariate Cox regression analysis using inverse probability of treatment weighting (IPTW) revealed that neoadjuvant chemohormonal therapy independently reduced the risk of biochemical recurrence after RP. The 5-year cost per person was significantly higher in the ePLND group than in the neoadjuvant group. Although the present study was retrospective, neoadjuvant chemohormonal therapy followed by RP as a concurrent strategy has potential to improve oncological outcome and cost-effectiveness.

Preoperative chronic kidney disease predicts poor oncological outcomes after radical nephroureterectomy in patients with upper urinary tract urothelial carcinoma.

OBJECTIVE: To evaluate the impact of preoperative chronic kidney disease (CKD) on oncological outcomes in patients with upper tract urothelial carcinoma who underwent radical nephroureterectomy. METHODS: A total of 426 patients who underwent radical nephroureterectomy at five medical centers between February 1995 and February 2017 were retrospectively examined. Oncological outcomes, including intravesical recurrence-free, visceral recurrence-free, cancer-specific, and overall survival rates (intravesical RFS, visceral RFS, CSS, and OS, respectively) stratified by preoperative CKD status (CKD vs. non-CKD) were investigated. Cox proportional hazards regression analysis was performed using inverse probability of treatment weighting (IPTW) to evaluate the impact of preoperative CKD on prognosis and a prognostic factor-based risk stratification nomogram was developed. RESULTS: Of the 426 patients, 250 (59%) were diagnosed with CKD before radical nephroureterectomy. Before the background adjustment, intravesical RFS, visceral RFS, CSS, and OS after radical nephroureterectomy were significantly shorter in the CKD group than in the non-CKD group. Background-adjusted IPTW analysis demonstrated that preoperative CKD was significantly associated with poor visceral RFS, CSS, and OS after radical nephroureterectomy. Intravesical RFS was not significantly associated with preoperative CKD. The nomogram for predicting 5-year visceral RFS and CSS probability demonstrated a significant correlation with actual visceral RFS and CSS (c-index = 0.85 and 0.83, respectively). CONCLUSIONS: Upper tract urothelial carcinoma patients with preoperative CKD had a significantly lower survival probability than those without CKD.

Presence of transient hydronephrosis immediately after surgery has a limited influence on renal function 1 year after ileal neobladder construction.

BACKGROUND: Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder construction. METHODS: Between January 2006 and June 2013, we performed radical cystectomy in 164 patients, and 101 received orthotopic ileal neobladder construction. This study included data available from 64 patients with 128 renal units who were enrolled retrospectively. The hydronephrosis grade of each renal unit scored 0-4. The patients were divided into 4 groups according to the grade of hydronephrosis: control, low, intermediate, and high. The grade of postoperative hydronephrosis was compared with renal function 1 month and 1 year after surgery. RESULTS: There were no significant differences in renal function before surgery between groups. One month after surgery, the presence of hydronephrosis was significantly associated with decreased renal function. However, 1 year after urinary diversion hydronephrosis grades were improved significantly, and renal function was comparable between groups. Postoperative hydronephrosis at 1 month had no significant influence on renal function 1 year after ileal neobladder construction. Limitations include retrospective design, short follow-up periods, and a sample composition. CONCLUSIONS: The presence of transient hydronephrosis immediately after surgery may have limited influence on renal function 1 year after ileal neobladder construction.

The influence of serum uric acid on renal function in patients with calcium or uric acid stone: A population-based analysis.

OBJECTIVES: To determine the influence of serum uric acid (UA) levels on renal impairment in patients with UA stone. MATERIALS AND METHODS: We retrospectively analyzed 463 patients with calcium oxalate and/or calcium phosphate stones (CaOx/CaP), and 139 patients with UA stones. The subjects were divided into the serum UA-high (UA ≥ 7.0 mg/dL) or the UA-low group (UA < 7.0 mg/dL). The control group comprised 3082 community-dwelling individuals that were pair-matched according to age, sex, body mass index, comorbidities, hemoglobin, serum albumin, and serum UA using propensity score matching. We compared renal function between controls and patients with UA stone (analysis 1), and between patients with CaOx/CaP and with UA stone (analysis 2). Logistic regression analysis was used to evaluate the impact of the hyperuricemia on the development of stage 3 and 3B chronic kidney disease (CKD) (analysis 3). RESULTS: The renal function was significantly associated with serum UA levels in the controls and patients with CaOx/CaP and UA stones. In pair-matched subgroups, patients with UA stone had significantly lower renal function than the control subjects (analysis 1) and patients with CaOx/CaP stones (analysis 2) regardless of hyperuricemia. Multivariate logistic regression analysis revealed that patients with UA stone, CaOx/CaP, hyperuricemia, presence of cardiovascular disease, higher body mass index, older age and lower hemoglobin had significantly higher risk of stage 3 and 3B CKD (analysis 3). CONCLUSION: Patients with UA stones had significantly worse renal function than controls and CaOx/CaP patients regardless of hyperuricemia. Urolithiasis (CaOx/CaP and UA stone) and hyperuricemia had an association with impaired renal function. Our findings encourage clinicians to initiate intensive treatment and education approaches in patients with urolithiasis and/or hyperuricemia in order to prevent the progression of renal impairment.

Overall survival of high-risk prostate cancer patients who received neoadjuvant chemohormonal therapy followed by radical prostatectomy at a single institution.

BACKGROUND: The optimal treatment for high-risk prostate cancer (PCa) remains to be established. We previously reported favorable, biochemical recurrence-free survival in high-risk PCa patients treated with a neoadjuvant gonadotropin-releasing hormone agonist or antagonist and estramustine phosphate (EMP) (chemohormonal therapy; CHT) followed by radical prostatectomy (RP). We conducted a retrospective study to elucidate the clinical benefit of neoadjuvant CHT for high-risk PCa patients. METHODS: We reviewed the clinical and pathological records of 1254 PCa patients who underwent RP and bilateral pelvic lymphadenectomy between July 1996 and April 2016 at Hirosaki University. According to the D'Amico risk classification, we focused on 613 patients in the high-risk group. The high-risk PCa patients were further divided into two groups based on whether the patients received neoadjuvant CHT before RP (EMP group) or not (non-EMP group). The endpoint was overall survival (OS) after surgery. RESULTS: The 5- and 10-year OS rates were 98.5 and 92.6%, respectively. The 10-year OS rate in the EMP group was significantly higher compared to the non-EMP group (P = 0.021). In multivariate analysis, administration of neoadjuvant CHT, lymph node involvement, and castration-resistant PCa status were significantly associated with OS. CONCLUSIONS: RP with neoadjuvant CHT using EMP for high-risk PCa patients provided excellent long-term OS.

Clinical relevance of aortic calcification in urolithiasis patients.

BACKGROUND: The aim of the present study is to investigate the clinical relevance of aortic calcification in urolithiasis patients. METHODS: Between January 2010 and September 2014, 1221 patients with urolithiasis were treated in Oyokyo Kidney Research Institute and Hirosaki University Hospital. Among these, 287 patients (Stone group) on whom adequate data were available were included in this retrospective study. We also selected 148 subjects with early stage (pT1N0M0) renal cell carcinoma from 607 renal cell carcinoma patients who underwent radical nephrectomy at Hirosaki University Hospital (Non-stone group) as control subjects. Validity of the Non-stone group was evaluated by comparison with pair-matched 296 volunteers from 1166 subjects who participated in the Iwaki Health Promotion Project in 2014. Thereafter, age, body mass index, aortic calcification index (ACI), renal function, serum uric acid concentrations, and comorbidities (diabetes, hypertension, or cardiovascular disease) were compared between the Non-stone and Stone groups. Independent factors for higher ACI and impaired renal function were assessed using multivariate logistic regression analysis. RESULTS: We confirmed relevance of Non-stone group patients as a control subject by comparing the pair-matched community-dwelling volunteers. Backgrounds of patients between the Non-stone and Stone groups were not significantly different except for the presence of hypertension in the Stone group. ACI was not significantly high in the Stone group compared with the Non-stone group. However, age-adjusted ACI was greater in the Stone group than the Non-stone group. Among urolithiasis patients, ACI was significantly higher in uric acid containing stone patients. The number of patients with stage 3B chronic kidney disease (CKD) was significantly higher in the Stone group than in the Non-stone group (12% vs. 4%, P = 0.008). Multivariate logistic regression analysis showed higher aortic calcification index (>13%), and being a stone former were independent factors for stage 3B CKD at the time of diagnosis. CONCLUSION: Aortic calcification and being a stone former had harmful influence on renal function. This study was registered as a clinical trial: UMIN: UMIN000022962.

Aortic calcification burden predicts deterioration of renal function after radical nephrectomy.

BACKGROUND: Radical nephrectomy for renal cell carcinoma (RCC) is a risk factor for the development of chronic kidney disease (CKD), and the possibility of postoperative deterioration of renal function must be considered before surgery. We investigated the contribution of the aortic calcification index (ACI) to the prediction of deterioration of renal function in patients undergoing radical nephrectomy. METHODS: Between January 1995 and December 2012, we performed 511 consecutive radical nephrectomies for patients with RCC. We retrospectively studied data from 109 patients who had regular postoperative follow-up of renal function for at least five years. The patients were divided into non-CKD and pre-CKD based on a preoperative estimated glomerular filtration rate (eGFR) of ≥60 mL/min/1.73 m2 or <60 mL/min/1.73 m2, respectively. The ACI was quantitatively measured by abdominal computed tomography before surgery. The patients in each group were stratified between low and high ACIs. Variables such as age, sex, comorbidities, and pre- and postoperative renal function were compared between patients with a low or high ACI in each group. Renal function deterioration-free interval rates were evaluated by Kaplan-Meier analysis. Factors independently associated with deterioration of renal function were determined using multivariate analysis. RESULTS: The median age, preoperative eGFR, and ACI in this cohort were 65 years, 68 mL/min/1.73 m2, and 8.3%, respectively. Higher ACI (≥8.3%) was significantly associated with eGFR decline in both non-CKD and pre-CKD groups. Renal function deterioration-free interval rates were significantly lower in the ACI-high than ACI-low strata in both of the non-CKD and pre-CKD groups. Multivariate analysis showed that higher ACI was an independent risk factor for deterioration of renal function at 5 years after radical nephrectomy. CONCLUSIONS: Aortic calcification burden is a potential predictor of deterioration of renal function after radical nephrectomy. TRIAL REGISTRATION: This study was registered as a clinical trial: UMIN000023577.

Quality-of-life evaluation during platinum-based neoadjuvant chemotherapies for urothelial carcinoma.

BACKGROUND: Although quality of life (QOL) is one of the most important considerations in patients treated with anticancer therapies, desirable regimens for neoadjuvant chemotherapy including QOL in locally advanced urothelial carcinoma remain unclear. The present study evaluated the influence of neoadjuvant platinum-based chemotherapy on QOL in patients with locally advanced urothelial carcinoma. METHODS: Between June 2013 and March 2016, 83 urothelial carcinoma patients who received two courses of neoadjuvant chemotherapy were enrolled in this prospective observational study. Neoadjuvant regimens included gemcitabine + cisplatin (GCis) or gemcitabine + carboplatin (GCb) therapies. As a primary endpoint, we assessed QOL changes in each group before and after chemotherapy using the Quality of Life questionnaire on days 1, 3, and 15 of each cycle. Secondary endpoints included toxicity, safety, weight loss, renal function decline, and tumor responses. RESULTS: QOL analyses were performed in 39 patients receiving GCis and in 44 patients receiving GCb. Appetite loss, role functioning, nausea/vomiting, physical, and fatigue deteriorated >10% from baseline in the GCis group but not in the GCb group. Constipation worsened, whereas scores for pain and emotional items improved in both groups. Objective response rates were 38.5 and 43.2% in the GCis and GCb groups, respectively. CONCLUSIONS: Both GCis and GCb regimens were feasible in terms of QOL. The GCb regimen may be associated with a better QOL status especially in regard to gastrointestinal symptoms.

Safety of heparin bridging therapy for transrectal ultrasound-guided prostate biopsy in patients requiring temporary discontinuation of antithrombotic agents.

BACKGROUND: Safety of heparin bridging therapy for transrectal ultrasound-guided prostate (TRUS) biopsy in patients requiring temporary discontinuation of antithrombotic therapy is unknown. This study aimed to assess the relationship between heparin bridging therapy and the incidence of complications after TRUS biopsy. METHODS: From January 2005 to November 2015, we performed 1307 consecutive TRUS biopsies on 1134 patients in our hospital. The patients were assigned to two groups: those without heparin bridging (the control group) and those with temporary discontinuation of antithrombotic agents with heparin bridging therapy (the bridging group). A 10-12-core TRUS biopsy was performed; the patients were evaluated for bleeding-related complications. RESULTS: Of 1134 patients, 1109 (1281 biopsies) and 25 (26 biopsies) were assigned to the control and bridging group, respectively. Patient background did not significantly differ between the control and bridging groups, except for age, history of diabetes, cardiovascular diseases, and CHADS2 scores. Compared with the control group, the bridging group showed a significantly higher rate of complication for any complication (35 vs. 8.3%, P < 0.001), bleeding-related complications (27 vs. 4.4%), and urinary tract infection (7.7 vs. 1.2%). No thromboembolic event was observed in the present study. Multivariate logistic analysis showed that heparin bridging therapy was a significant risk factor for the incidence of any complication and bleeding-related complications. CONCLUSIONS: Heparin bridging therapy with temporal discontinuation of antithrombotic agents may increase the risk of complications after TRUS biopsy. Further, large-scale studies are required to clarify the safety of heparin bridging therapy.

[Management of High-Risk Prostate Cancer and Left Ectopic Ureter Inserting into Seminal Vesicle with Ipsilateral Hypoplastic Kidney of a Young Patient : A Case Report].

A 44-year-old male patient visited our hospital with a chief complaint of macroscopic hematuria. Prostate biopsies were performed due to prostate specific antigen (PSA) 11.6 ng/ml, and he was diagnosed with Gleason score 5＋4 prostate cancer. Computed tomography showed a left hypoplastic kidney. T2- weighted magnetic resonance imaging showed the left ureter stump with ectopic insertion into the dilated left seminal vesicle. He was diagnosed with high-risk prostate cancer and left ectopic ureter inserting into the seminal vesicle with ipsilateral hypoplastic kidney. Laparoscopic left nephroureterectomy and open radical prostatectomy were performed.

Eviprostat has an identical effect compared to pollen extract (Cernilton) in patients with chronic prostatitis/chronic pelvic pain syndrome: a randomized, prospective study.

BACKGROUND: Previously reported results of a prospective, randomized placebo-controlled study showed that the pollen extract (Cernilton) significantly improved total symptoms, pain, and quality of life in patients with inflammatory prostatitis/chronic pelvic pain syndrome (CP/CPPS) without severe side effects. A phytotherapeutic agent, Eviprostat, is reportedly effective in a rat model of nonbacterial prostatitis. The aim of the present study was to compare the efficacy and safety of Eviprostat to that of the pollen extract in the management of CP/CPPS. METHODS: The patients with category III CP/CPPS were randomized to receive either oral capsules of Eviprostat (two capsules, q 8 h) or the pollen extract (two capsules, q 8 h) for 8 weeks. The primary endpoint of the study was symptomatic improvement in the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). Participants were evaluated using the NIH-CPSI and the International Prostate Symptom Score (IPSS) at baseline and after 4 and 8 weeks. RESULTS: In the intention-to-treat analysis, 100 men were randomly allocated to Eviprostat (n = 50) or the pollen extract (n = 50). Response (defined as a decrease in the NIH-CPSI total score by at least 25 %) in the Eviprostat group and the pollen extract group was 88.2 and 78.1 %, respectively. There was no significant difference in the total, pain, urinary, and quality of life (QOL) scores of the NIH-CPSI between the two groups at 8 weeks. This was also the case with the total, voiding, and storage symptoms of the IPSS. There were no severe adverse events observed in any patients in this study. CONCLUSION: Both the pollen extract and Eviprostat significantly reduced the symptoms of category III CP/CPPS without any adverse events. Eviprostat may have an identical effect on category III CP/CPPS compared the pollen extract. TRIAL REGISTRATION: The study was registered with the University Hospital Medical Information Network Clinical Trials Registry in Japan (UMIN000019618); registration date: 3 November 2015.

Salvage Brachytherapy for Castration-Resistant and External Beam Radiotherapy-Resistant Local Recurrence 17 Years after Radical Prostatectomy.

A 47-year-old Japanese man was diagnosed with prostate cancer in February 1995 (Initial PSA 77.2 ng/mL, GS3 + 4, cT3N0M0). He underwent radical prostatectomy after androgen deprivation therapy (ADT) in June 1995. Nine years after operation, he was diagnosed with local recurrence of prostate cancer and he received postoperative external beam radiation therapy (EBRT) (70 Gy). By May 2008, the PSA dropped to 0.33 ng/mL, and a CT scan showed that the mass had disappeared. On April 2012, the PSA once again rose to 3.1 ng/mL. CT scan and MRI revealed a mass in the prostatic bed. We diagnosed local recurrence of prostate cancer. We underwent salvage low-dose brachytherapy after obtaining informed consent. The prescribed dose of the salvage brachytherapy was 145 Gy to control the tumor considering the hormone resistant prostatic cancer and high-risk feature. PSA level rapidly decreased to 0.66 ng/mL by 6 months after seed implantation. No adverse events were seen during the follow-up period.
