RESUMEN
OBJECTIVES: The objective of this study is to assess the trends in treatment selection for patients with de novo metastatic castration-sensitive prostate cancer in the era of upfront combination therapy. METHODS: This multicenter retrospective study included 595 patients treated with either upfront combination therapy (upfront novel hormonal therapies and taxane-based chemotherapy) or vintage therapy (androgen deprivation therapy with or without bicalutamide) between 2016 and 2021. High tumor burden metastatic disease was defined when a patient met the CHAARTED or LATITUDE criteria. We evaluated trends in treatment selection and reasons for selecting vintage therapy. RESULTS: Of the 595, 123 and 472 patients were classified as having low and high tumor-burden disease, respectively. The Use of upfront combination therapy was found to be rapidly increasing with utilization rates of 72% and 54% in 2021 for high and low tumor-burden disease, respectively. Multivariable logistic regression analysis found older age, poor performance status, and nonacademic center were significantly associated with the selection of vintage therapy. Of the 163 patients who received vintage hormone therapy after approval of upfront therapy, 74.2% had a specific reason for avoiding upfront therapy. The reasons for selecting vintage therapy included refusal (39.8%), older age (67.6%), frailty (56.3%), and comorbidity (40.8%). Furthermore, 16.9% of patients declined upfront combination therapy due to cost concerns. CONCLUSION: Upfront combination therapy use has 72% and 54% prevalence among patients with high and low tumor burden diseases, respectively, in this current practice. Older age, poor performance status, and facility bias were negatively associated with the use of upfront combination therapy.
RESUMEN
PURPOSE: To evaluate the impact of severe acute kidney injury (AKI) on short-term mortality in patients with urosepsis. METHODS: This prospective cohort study evaluated 207 patients with urosepsis. AKI was diagnosed in accordance with the Kidney Disease Improving Global Outcomes criteria, and severe AKI was defined as stage 2 or 3 AKI. Patients were divided into two groups: patients who developed severe AKI (severe AKI group) and patients who did not (control group). The primary endpoint was all-cause mortality within 30 days. The secondary endpoints were 90-day mortality and in-hospital mortality. The exploratory outcomes were the risk factors for severe AKI development. RESULTS: The median patient age was 79 years. Of the 207 patients, 56 (27%) developed severe AKI. The 30-day mortality rate in the severe AKI group was significantly higher than that in the control group (20% vs. 2.0%, respectively; P < 0.001). In the multivariable analysis, performance status and severe AKI were significantly associated with 30-day mortality. The in-hospital mortality and 90-day mortality rates in the severe AKI group were significantly higher than those in the control group (P < 0.001 and P < 0.001, respectively). In the multivariable analysis, age, urolithiasis-related sepsis, lactate values, and disseminated intravascular coagulation were significantly associated with severe AKI development. CONCLUSIONS: Severe AKI was a common complication in patients with urosepsis and contributed to high short-term mortality rates.

PURPOSE: We assessed the association between oral frailty risk and LUTS among middle-aged and older adults in a community-dwelling population. METHODS: This cross-sectional study was conducted among 586 subjects aged ≥ 40 years who participated in the Iwaki Health Promotion Project in Hirosaki, Japan. We used the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS) to assess LUTS. LUTS was defined as an IPSS score of 8 or higher or meeting diagnostic criteria for OAB. Oral frailty risk was defined as experiencing two or more of the following: decreased chewing ability, decreased biting force, and dry mouth sensation. Physical performance (10-m gait speed and grip strength) was used for analysis. The association between oral frailty risk and LUTS was examined using multivariate logistic regression analyses. RESULTS: The study included 218 men and 370 women, of whom 140 had LUTS. The mean age of this cohort was 59 years. Significant differences were observed between the LUTS and non-LUTS groups, including age, hypertension, history of CVD, depressive status, sleep disturbance, and 10 m gait speed. The prevalence of oral frailty risk was significantly higher in the LUTS group than in the non-LUTS group (26% vs. 11%, P < 0.001). Multivariate analysis revealed that age, male gender, and oral frailty risk (odds ratio: 2.67, 95% confidence interval: 1.57-4.51, P < 0.001) were independent factors for LUTS. Moreover, oral frailty risk was an independent factor in both participants aged < 65 years and participants aged ≥ 65 years. CONCLUSIONS: Oral frailty was independently associated with LUTS.

OBJECTIVE: To elucidate the relationship between frailty and lower urinary tract symptoms (LUTS). METHODS: We longitudinally evaluated the temporal changes and the relationships between frailty and LUTS in 247 community-dwelling adults (45 years or older) at baseline and at a 5-year follow-up. We used the Fried phenotype (phenotype-based frailty), 5-item modified frailty index (5i-mFI; comorbidity-based frailty), and frailty discriminant score (comprehensive frailty assessment) to evaluate frailty. LUTS were evaluated using the international prostate symptom score (IPSS) and overactive bladder symptom score (OABSS). RESULTS: We analyzed 247 participants with a median age of 60 years. The median IPSS and OABSS were significantly increased over the 5 years. The proportion of frail individuals did not increase significantly over the 5 years. Of the three frailty assessment tools, the 5i-mFI score significantly increased between 2014 and 2019. Multiple linear regression analyses showed that the 5i-mFI score was significantly associated with the severity of LUTS in 2014 to 5i-mFI in 2019 but not with 5i-mFI in 2014 to the severity of LUTS in 2019. CONCLUSION: The effect of LUTS on frailty might be greater than the effect of frailty on LUTS. Further large-scale studies are needed to elucidate the relationship between LUTS and frailty.

Background: The estimation of biological age is challenging in patients with cancers. We aimed to investigate frailty-based biological ages using frailty-discriminant scores (FDS) and examined the effect of biological-expected life age discrepancy on the prognosis of patients with urological cancers. Methods: We retrospectively evaluated frailty in 1035 patients having urological cancers. Their frailty-based biological age was then defined by the FDS, which is a comprehensive frailty assessment tool, using 1790 noncancer individuals as controls. An expected life age (=chronological age + life expectancy) was subsequently calculated using the 2019 life expectancy table. The primary outcome was the estimation of the biological-expected life age discrepancy between the frailty-based biological age and expected life age in patients with urological cancers. Secondary outcomes were the evaluation of the effect of the biological-expected life age discrepancy on overall survival. Results: We included 405, 466, and 164 patients diagnosed with prostate cancer, urothelial carcinoma, and renal cell carcinoma, respectively. The median chronological age, life expectancy, and estimated frailty-based biological age were 71, 17, and 83 years, respectively. The biological-expected life age discrepancy in any urological cancers, localized diseases, and metastatic diseases was −4.8, −6.3, and +0.15 years, respectively. The biological-expected life age discrepancy of >5 years was significantly associated with poor overall survival. Conclusions: The biological-expected life age discrepancy between frailty-based biological age and expected life age may be helpful in understanding the role of frailty and patient/doctor conversation.
RESUMEN
OBJECTIVES: To evaluate the association between the score of the Geriatric 8 screening tool and treatment by disease stages in patients with prostate cancer. METHODS: Between January 2017 and June 2019, we prospectively evaluated the Geriatric 8 in 540 prostate cancer patients who were treated with robot-assisted radical prostatectomy, radiotherapy, androgen deprivation therapy alone and standard of care for metastatic hormone-naïve prostate cancer or castration-resistant prostate cancer. The primary purpose was the association between frailty (Geriatric 8 ≤14) and robot-assisted radical prostatectomy, radiotherapy, androgen deprivation therapy alone, and metastatic diseases. Secondary purposes included a comparison of the Geriatric 8 scores among the disease status and the influence of Geriatric 8 score on overall survival. RESULTS: The median age was 75 years. Geriatric 8 scores ≤14 were seen in 36% of robot-assisted radical prostatectomy (n = 78/214), 57% of radiotherapy (n = 119/209), 91% of androgen deprivation therapy alone (n = 19/21) and 70% of metastatic diseases (n = 67/96). The median Geriatric 8 score in patients treated with robot-assisted radical prostatectomy, radiotherapy, androgen deprivation therapy alone and metastatic diseases was 15.0, 14.0, 12.0 and 12.8, respectively. The median Geriatric 8 score was significantly higher in the metastatic disease than that in localized disease (14.5 vs 12.8, respectively). Robot-assisted radical prostatectomy patients had a significantly higher Geriatric 8 score than radiotherapy patients, with the cut-off value of <14.5. The overall survival was significantly different between Geriatric 8 scores ≤13 and >13 in metastatic hormone-naïve prostate cancer patients, and between Geriatric 8 scores ≤12 and >12 in castration-resistant prostate cancer patients. CONCLUSION: The Geriatric 8 score is significantly associated with treatment by disease stages in patients with prostate cancer.

OBJECTIVES: To investigate the effect of frailty on the type of urinary diversion after radical cystectomy in patients with muscle-invasive bladder cancer. METHODS: Between January 2014 and January 2020, we prospectively evaluated frailty in 88 patients with localized muscle-invasive bladder cancer, who had received radical cystectomy and urinary diversion. The selection of the type of urinary diversion was determined by the operating surgeon based on performance status, comorbidities, tumor status and the patient's preference. The frailty evaluation included the Fried phenotype criteria, the modified frailty index and the frailty discriminant score. We investigated the association between frailty and type of urinary diversion, the effect of frailty on postoperative complications and the effect of frailty on overall survival. RESULTS: The median age of the selected participants was 68 years. The number of patients with an orthotopic neobladder and any postoperative complications was 54 (61%) and 46 (52%), respectively. Of the frailty assessment tools that were used, Fried phenotype criteria and frailty discriminant score were significantly associated with the selection of non-orthotopic neobladder urinary diversion. Occurrences of postoperative complications in participants were significantly associated with modified frailty index, but not with Fried phenotype criteria and frailty discriminant score. Multivariate Cox regression analysis showed that a higher frailty discriminant score was significantly associated with poor overall survival, whereas higher Fried phenotype criteria and modified frailty index were not. CONCLUSION: Frailty is significantly associated with the type of urinary diversion, and it should be considered for the selection of urinary diversion in muscle-invasive bladder cancer patients undergoing radical cystectomy.

Objective: To investigate the association of pain with frailty in patients with localized prostate cancer (PC) who underwent robot-assisted laparoscopic radical prostatectomy (RARP). Materials and Methods: Between January 2017 and June 2019, we prospectively evaluated the geriatric 8 (G8) score, simplified frailty index (sFI), and numerical rating scale (NRS) of 154 patients with localized PC who underwent RARP at our institution. NRS was measured on preoperative day 0, postoperative days 1, 2, 3, and at discharge. Moderate to severe pain was defined as NRS ≥ 5, whereas frailty was defined as G8 ≤ 14. The primary objectives of this study were to investigate the effects of moderate to severe pain (NRS ≥ 5) on frailty, postoperative complications, and the use of analgesics after RARP. Our secondary objectives were the effect of frailty on postoperative complications and the use of analgesics. Results: The median age of participants was 69 years. Of 154 patients, 37 (24%) and 61 (40%) were classified to have NRS ≥ 5 and G8 ≤ 14, respectively. Patients with NRS > 5 presented significantly association with G8 < 14, whereas they did not show the association with sFI, complication, or analgesics. Multivariate logistic regression analysis showed that G8 ≤ 14 was significantly associated with NRS ≥ 5. Frailty was not significantly associated with postoperative complications and analgesics. Conclusions: Frailty was significantly associated with moderate to severe pain after RARP, and might be a potential predictor of postoperative pain. Frail patients require individual care to avoid painful experiences.
RESUMEN
BACKGROUND: To evaluate whether serum N-glycan profile can be used as a diagnostic marker of graft rejection after living-donor kidney transplants (KT). METHODS: We retrospectively examined 174 KT recipients at five medical centers. N-Glycan levels were analyzed in postoperative serum samples using glycoblotting combined with mass spectrometry. We developed an integrated score to predict graft rejection based on a combination of age, gender, immunological risk factors, and serum N-glycan levels at post-KT day D1 and D7. Rejection-free survival rates stratified by the sum of integrated scores (D1 + D7) were evaluated using Kaplan-Meier curves. RESULTS: Of 174, 52 showed graft rejection (Rejection-pos. group) and 122 recipients did not show graft rejection (Rejection-neg. group). The integrated scores were significantly higher in the Rejection-pos. group than those of the Rejection-neg. group. Area-under-curve (AUC) value of integrated scores at post-KT D1, and D7 were 0.84 and 0.84, respectively. The sum of integrated scores (D1 + D7) ≥ 0.50 identified graft rejection with 81% sensitivity and 80% specificity; with an AUC value of 0.87. Recipients with higher sum of integrated scores (D1 + D7 ≥ 0.5) had significantly shorter rejection-free survival than those with lower scores. CONCLUSION: Evaluation of serum N-glycosylation profiles can identify recipients who are prone to rejection.

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.

We prospectively validate the efficacy of the frailty discriminant score (FDS) in individuals with urological cancers, as there has been growing importance in evaluating frailty in clinical practice. A prospective, multicenter study was conducted from February 2017 to April 2019. We enrolled 258 patients with urological cancers and 301 community-dwelling participants who were assessed for frailty. Frailty was assessed using FDS that includes ten items, such as physical, mental, and blood biochemical tests. The primary outcome was the non-inferiority (margin 5%) of FDS in discriminating patients with urological cancers from controls (Ctrl). The sensitivity, specificity, and area under the receiver operating characteristic (AUROC) curve for each predictive test were calculated. The secondary endpoints included the prediction of overall survival between patients with urological cancer who have high and low FDS. FDS was significantly higher in patients with urological cancers than that in the Ctrl. The AUROC curves for individuals with non-prostate cancers (such as bladder cancer, upper tract urothelial carcinoma, and renal cell carcinoma; 0.942) and those with prostate cancer (0.943) were within the non-inferior margin. The overall survival values were significantly lower in patients with higher FDS score than in those with lower FDS score. The study met its primary and secondary endpoints. The FDS is a reliable and valid tool for assessing frailty and prognosis in patients with urological cancers.

INTRODUCTION: Lumbar ectopic kidney is a rare developmental renal anomaly. We report a case of renal cell carcinoma in lumbar ectopic kidney with an abnormality of the main renal artery piercing the renal parenchyma. CASE PRESENTATION: A 70-year-old female was referred to our division with an incidentally diagnosed ectopic kidney. Computed tomography angiography detected the right kidney at the lumbar (L3-L4) level with an early-enhanced 44-mm-diameter mass. The kidney had a laterally facing renal hilum and renal arteries piercing the renal parenchyma from the medial side. An open radical nephrectomy was performed using a peritoneal approach, and no perioperative complications were observed. The pathological diagnosis was clear cell carcinoma (pT1). CONCLUSION: This is the first case report of renal cell carcinoma in a lumbar ectopic kidney. It highlights the importance of preoperational imaging for aberrant artery and careful surgical management.
RESUMEN
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.
RESUMEN
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.

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.
RESUMEN
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.

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.

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.

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.

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.
