RESUMO
OBJECTIVES: To investigate the impact of global aging on the trends in the age of hospitalized patients with a urological cancer diagnosis. METHODS: We retrospectively evaluated a cumulative total of 10 652 cases of referred patients (n = 6637) with a urological disease who were hospitalized in our institution between January 2005 and December 2021. We compared age and the proportion of patients aged ≥80 years among patients who were hospitalized in the urological ward between the period of 2005-2013 and that of 2014-2021. RESULTS: We identified 8168 hospitalized patients with urological cancer. The median age was significantly increased in patients with urological cancer between the periods of 2005-2013 and 2014-2021. The proportion of hospitalized patients with urological cancer aged ≥80 years was significantly increased between the periods of 2005-2013 (9.3%) and 2014-2021 (13.8%). The median ages of the patients with urothelial cancer (UC) and renal cell carcinoma (RCC), but not the median age of those with prostate cancer (PC), were significantly increased between the study periods. The proportion of hospitalized patients with UC, but not the proportions of those with PC and RCC, aged ≥80 years was significantly increased between the study periods. CONCLUSIONS: The age of patients with urological cancer who were hospitalized in the urological ward and the proportion of patients with UC aged ≥80 years significantly increased over the entire study period.

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.

BACKGROUND: Although aortic calcification has a significant negative impact on prognosis in patients on hemodialysis (HD), risk factors for aortic calcification progression remain unclear. The aim of this study was to investigate the relationship between malnutrition and aortic calcification progression in patients on HD. METHODS: Between April 2015 and October 2016, we treated 232 patients on HD. Of those, we retrospectively evaluated data from 184 patients who had had regular blood tests and computed tomography (CT) scans. The abdominal aortic calcification index (ACI) was quantitatively measured by abdominal CT. Nutritional status was evaluated using the Geriatric Nutritional Risk Index (GNRI). A normalized treatment ratio of functional urea clearance was evaluated by Kt/V. The difference in ACI values between 2015 and 2016 was evaluated as a ΔACI, and patients were stratified into two groups according to ΔACI value: high (≥75th percentile, ΔACI-high group) and low (<75th percentile, ΔACI-low group). Variables such as age, sex, comorbidities, dialysis vintage, serum data, and GNRI were compared between ΔACI-high and ΔACI-low patients. Factors independently associated with a higher ΔACI progression (ΔACI ≥75th percentile) were determined using multivariate logistic analysis. RESULTS: Median values of ACIs in 2015 and 2016 were 40.8 and 44.6%, respectively. Of 184 patients, 125 (68%) patients experienced ACI progression for 1 year. The median ΔACI and 75th percentile of ΔACI were 2.5% and 5.8%, respectively. The number of patients in the ΔACI-low and ΔACI-high groups were 128 (70%) and 56 (30%), respectively. There were significant differences in sex, presence of diabetic nephropathy, HD vintage, serum albumin, serum phosphate, C-reactive protein, intact parathyroid hormone, Kt/V, and GNRI. Multivariate logistic regression analysis revealed that independent factors associated with a higher ΔACI progression were male sex, serum phosphate levels, HD vintage, and GNRI of < 90. CONCLUSIONS: Our results suggest that poor nutritional status is an independent risk factor for the progression of aortic calcification. Nutrition management may have the potential to improve progression of aortic calcification in patients on HD. TRIAL REGISTRATION: UMIN Clinical Trials Registry UMIN000028050 .

OBJECTIVES: The aim of this study was to analyze the features of incidentally detected prostate cancer (PCa) in radical cystoprostatectomy (RCP) specimens to determine their pathological characteristics and clinical significance. METHODS: In this retrospective study, we reviewed the clinical and pathological records of 431 consecutive patients with muscle-invasive bladder cancer who underwent RCP at Hirosaki University. Of these, we focused on 237 male patients with prostate-specific antigen (PSA) measurements and digital rectal examinations (DRE) that were recorded prior to the RCP. Significant PCa was defined as a tumor with a Gleason 4 or 5 pattern, pathological T3 or higher stage, lymph node involvement or three or more multifocal lesions within the prostate specimen. We compared clinically significant and insignificant PCa. RESULTS: In this study, a total of 43 patients (18.1%) were diagnosed with incidental PCa via RCP specimens. Age, preoperative PSA levels and pathological T stage in patients with clinically significant PCa were considerably higher than in those with insignificant cancer. Apical involvement was found in 16 patients, including 11 of those with clinically significant PCa. By the end of the follow-up period, none of the enrolled patients had a biochemical recurrence after surgery or died from PCa. CONCLUSION: According to our findings, preoperative risk factors were not reliable enough to accurately predict clinically significant PCa. Although there was no biochemical relapse or clinical recurrence of PCa in this study, the potential oncologic risk of prostate-sparing RCP must be considered.

BACKGROUND: Although continuous surveillance after a 5-year cancer-free period in patients with bladder cancer (BC) who undergo radical cystectomy (RC) is recommended, optimal candidates for continuous surveillance remain unclear. Sarcopenia is associated with unfavorable prognosis in various malignancies. We aimed to investigate the impact of low muscle quantity and quality (defined as severe sarcopenia) on prognosis after a 5-year cancer-free period in patients who underwent RC. METHODS: We conducted a multi-institutional retrospective study assessing 166 patients who underwent RC and had five years or more of follow-up periods after a 5-year cancer-free period. Muscle quantity and quality were evaluated using the psoas muscle index (PMI) and intramuscular adipose tissue content (IMAC) using computed tomography images five years after RC. Patients with lower PMI and higher IMAC values than the cut-off values were diagnosed with severe sarcopenia. Univariable analyses were performed to assess the impact of severe sarcopenia on recurrence, adjusting for the competing risk of death using the Fine-Gray competing risk regression model. Moreover, the impact of severe sarcopenia on non-cancer-specific survival was evaluated using univariable and multivariable analyses. RESULTS: The median age and follow-up period after the 5-year cancer-free period were 73 years and 94 months, respectively. Of 166 patients, 32 were diagnosed with severe sarcopenia. The 10-year RFS rate was 94.4%. In the Fine-Gray competing risk regression model, severe sarcopenia did not show a significant higher probability of recurrence, with an adjusted subdistribution hazard ratio of 0.525 (p = 0.540), whereas severe sarcopenia was significantly associated with non-cancer-specific survival (hazard ratio 1.909, p = 0.047). These results indicate that patients with severe sarcopenia might not need continuous surveillance after a 5-year cancer-free period, considering the high non-cancer-specific mortality.
RESUMO
OBJECTIVES: To examine the oncological and urinary functional outcomes of reproductive organ-sparing radical cystectomy (ROS-RC) and U-shaped ileal neobladder construction in females compared with male patients. METHODS: We retrospectively examined 357 patients (281 male and 76 female) with muscle-invasive bladder cancer who were treated with RC plus U-shaped ileal neobladder construction between May 1996 and July 2021. All female patients were treated with ROS-RC. We compared disease-free survival (DFS), cancer-specific survival (CSS), overall survival (OS), and urinary functional outcomes between male and female patients. We evaluated the effect of gender on DFS, CSS, and OS. Furthermore, urinary functional outcomes were evaluated in 140 males and 48 females using a pressure-flow study at 3, 6, 9, and 12 months postoperatively. RESULTS: Female patients were considerably older than male patients at the time of radical cystectomy. No significant difference was noted in the tumor stage preoperatively. The multivariable Cox regression analysis with an inverse probability treatment weighted model revealed that the female gender was not significantly related to DFS, CSS, and OS. Moreover, urinary functions at 12 months were not markedly different between males and females, except for the capacity of the neobladder, detrusor pressure, and maximum urethral closure pressure. CONCLUSIONS: This study demonstrates that female patients with ROS-RC and U-shaped ileal neobladder construction did not significantly correlate with worse oncological outcomes. The combination of ROS-RC and U-shaped ileal neobladder construction might attain adequate urinary function without sacrificing oncologic outcomes.

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.
RESUMO
We aimed to determine the survival and staging benefit of limited pelvic lymph node dissection (PLND) during radical prostatectomy (RP) in high-risk prostate cancer (PC) patients treated with neoadjuvant chemohormonal therapy. We retrospectively analyzed 516 patients with high-risk localized PC (< cT4N0M0) who received neoadjuvant androgen-deprivation therapy plus estramustine phosphate followed by RP between January 2010 and March 2020. Since we stopped limited PLND for such patients in October 2015, we compared the surgical outcomes and biochemical recurrence-free survival (BCR-FS) between the limited-PLND group (before October 2015, n = 283) and the non-PLND group (after November 2015, n = 233). The rate of node metastases in the limited-PLND group were 0.8% (2/283). Operation time was significantly longer (176 vs. 162 min) and the rate of surgical complications were much higher (all grades; 19 vs. 6%, grade ≥ 3; 3 vs. 0%) in the limited-PLND group. The inverse probability of treatment weighting-Cox analysis revealed limited PLND had no significant impact on BCR-FS (hazard ratio, 1.44; P = 0.469). Limited PLND during RP after neoadjuvant chemohormonal therapy showed quite low rate of positive nodes, higher rate of complications, and no significant impact on BCR-FS.

Objectives: To investigate the eligibility for maintenance immunotherapy and its impact on the prognosis of advanced urothelial carcinoma treated with first-line chemotherapy, as the selection biases of the eligible population in the JAVELIN Bladder 100 trial remain unclear. Methods: We retrospectively evaluated 213 patients (median age, 71 years) with unresectable locally advanced or metastatic urothelial carcinoma treated with platinum-based first-line chemotherapy between May 2003 and April 2021. The patients were categorized into the following two groups: progressive disease (PD) within four cycles (trial ineligible group) and non-PD within four cycles (trial eligible group). The primary outcomes were the estimated proportion of trial eligible patients for maintenance immunotherapy. The secondary outcomes were the comparison of the overall survival in the trial eligible and ineligible groups and the impact of radiologic response at the second cycle on the fourth cycle. Results: Among the 213 patients, 81 (38%) were included in the trial eligible group. The trial eligible group had a significantly longer overall survival than the trial ineligible group (P < 0.001). Of 166 patients who had no PD within two cycles, 85 (51%) patients experienced PD within four cycles. Patients with a complete response or partial response at the second cycle had a significantly lower rate of PD at the fourth cycle (42%) than those with stable disease at the second cycle (59%, P = 0.031). Conclusion: We observed 38% of the trial eligible population. Overall survival was significantly different between the trial eligible and ineligible groups.
RESUMO
Objective: To evaluate the effect of postoperative pathological findings related to the eligibility of adjuvant immunotherapy on oncologic outcomes in patients with localized and locally advanced muscle-invasive bladder carcinoma (MIBC) and upper tract urothelial carcinoma (UTUC). Patients and methods: We retrospectively evaluated 1082 patients treated with radical cystectomy (n = 597) and nephroureterectomy (n = 485) between January 2000 and April 2021. Patients were divided into two groups: pT3-4 or pN+ without neoadjuvant chemotherapy and ypT2-4 or pN+ treated with neoadjuvant chemotherapy (trial-eligible group) or others (trial-ineligible group). The primary outcome was the effect of trial eligibility for adjuvant immunotherapy on disease-free survival (DFS) and overall survival (OS). Secondary outcomes included the additional effect of lymphovascular invasion (LVI) status to the clinical trial criteria on prognosis and a risk model development. Results: The median ages of the patients were 69 and 72 years in the MIBC and UTUC groups, respectively. Fifty-two percent of patients met the trial inclusion criteria. Trial eligibility was significantly associated with poor DFS and OS among patients with MIBC and UTUC. LVI-positive status was significantly associated with poor prognosis among patients in the trial-eligible group. A very high risk (LVI+ or pN+ among the pT3-4 or ypT2-4) was significantly associated with poor prognosis. Conclusion: A total of 52% of patients were eligible for adjuvant immunotherapy. Trial eligibility was significantly associated with a poor prognosis. LVI+ and pN+ may play a key role in candidate selection for adjuvant immunotherapy.
RESUMO
OBJECTIVES: To investigate the association between Ki67 index and programmed death-ligand 1 (PD-L1) expression in muscle-invasive bladder cancer (MIBC) patients after RC. MATERIALS AND METHODS: We retrospectively evaluated 262 MIBC patients treated with RC between April 2004 and April 2020. The impact of Ki67 index and PD-L1 expression on prognosis was evaluated by univariate Cox regression analysis. In addition, a pathomolecular risk score, including Ki67 and PD-L1, was developed to predict prognosis and pathological factors. We also evaluated the link between the Ki67 index and PD-L1 under the IL-6 stimulation in the bladder cancer cell lines of T24 and 5637 cells. RESULTS: The median age and follow-up period was 69 years and 52 months, respectively. Ki67 index and PD-L1 expression were significantly associated with tumor recurrence. Univariate Cox regression analysis showed that pT3-4, mixed histology, lymphovascular invasion positive (LVI+), pN+, Ki67-high (>17%), and PD-L1+ were significantly associated with recurrence-free survival (RFS). The pathomolecular risk score was developed using resection margin+ (1 point), mixed histology (1 point), LVI+ (1 point), pN+ (1 point), and Ki67-high (1 point). RFS and overall survival were significantly shorter in patients with higher pathomolecular risk scores (>1) than in those with lower risk scores (≤1). Cell proliferation was significantly increased in the T24 and 5637 cells under the IL-6 stimulation, while PD-L1 expression was not. CONCLUSIONS: A significant effect of Ki67-high and PD-L1 expression on poor prognosis was observed in patients with MIBC. Further studies are necessary to elucidate the precise mechanisms of cell proliferation and PD-L1 expression in patients with MIBC.

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.
RESUMO
The clinical benefits of bacillus Calmette-Guérin (BCG) therapy for the management of upper urinary tract carcinoma in situ (CIS) remain unclear. We aimed to compare the efficacy and safety of BCG therapy for upper urinary tract CIS with those of radical nephroureterectomy (RNU). Of 490 patients with upper urinary tract carcinoma, we retrospectively reviewed the post-treatment course of 58 patients with upper urinary tract CIS who underwent either RNU (RNU group) or BCG therapy (BCG group). Efficacy and safety were compared between the RNU and BCG groups. Inverse probability treatment-weighted (IPTW)-adjusted multivariate Cox regression analysis was performed to identify the influence of BCG therapy on prognosis. The RNU and BCG groups included 20 and 38 patients, respectively. No significant difference was found in patients' background, including age, sex, and performance status, between the groups. The reason underlying the selection of BCG therapy was bilateral CIS of the upper urinary tract (50%), solitary kidney (26%), unwillingness to undergo RNU (13%), and ineligibility for surgery (11%). The cytology became negative in 30 (79%) out of 38 patients after a 6-week course of BCG therapy, and 17 (57%) out of 30 patients remained negative. BCG-related adverse events (AEs) were observed in 92% of patients. The most common AE was cystitis (76%), followed by fever (50%). No significant differences were found in the progression-free, cancer-specific, and overall survivals between the RNU and BCG groups. IPTW-adjusted multivariate analysis revealed that BCG therapy did not worsen the prognosis of these patients. The limitations of our study were its retrospective design and small sample size. In conclusion, BCG therapy for upper urinary tract CIS might be a useful alternative for patient ineligible for RNU under careful observation for AEs.

BACKGROUND: The prognostic benefit of regular follow-up to detect asymptomatic recurrence after radical nephroureterectomy (RNU) remains unclear. We aimed to assess whether regular follow-up to detect asymptomatic recurrence after RNU improves patient survival. MATERIALS AND METHODS: We retrospectively analysed 415 patients who underwent RNU for upper tract urothelial carcinoma at four hospitals between January 1995 and February 2017. All patients had regular follow-up examinations after RNU including urine cytology, blood biochemical tests, and computed tomography. We investigated the first site and date of tumor recurrence. Overall survivals of patients who developed recurrence, stratified by mode of recurrence (asymptomatic vs. symptomatic group), were estimated using the Kaplan-Meier method with the log-rank test. Cox proportional hazards regression analysis was performed using inverse probability of treatment weighting (IPTW) to evaluate the impact of the mode of recurrence on survival. RESULTS: Of the 415 patients, 108 (26%) experienced disease recurrences after RNU. Of these, 62 (57%) were asymptomatic and 46 (43%) were symptomatic at the time of diagnosis. The most common recurrence site and symptom were lymph nodes and pain, respectively. Overall survival after RNU and time from recurrence to death in the asymptomatic group were significantly longer than that in the symptomatic group. Multivariate Cox regression analysis showed that symptomatic recurrence was an independent risk factor for overall survival after RNU and survival from recurrence to death. CONCLUSIONS: Routine oncological follow-up for detection of asymptomatic recurrence contributes to a better prognosis after RNU.
RESUMO
Temsirolimus did not demonstrate an efficacy advantage compared with sorafenib as second-line therapy in patients with metastatic renal cell carcinoma (mRCC). Only a few patients achieved complete responses, and the median progression-free survival rate remains short. We report one patient with mRCC who had a continuing response to temsirolimus.
RESUMO
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.
