RESUMEN
CD46, a transmembrane protein known for protecting cells from complementmediated damage, is frequently dysregulated in various types of cancer. Its overexpression in bladder cancers safeguards the cancer cells against both complement and antibodymediated cytotoxicity. The present study explored a new role of CD46 in facilitating cancer cell invasion and metastasis, examining its regulatory effect on matrix metalloproteases (MMPs) and their effect on the metastatic capability of bladder cancer cells. Specifically, CD46 alteration positively influenced MMP9 expression, but not MMP2, in several bladder cancer cell lines. Furthermore, CD46 overexpression triggered phosphorylation of p38 MAPK and protein kinase B (AKT), leading to enhanced activator protein 1 (AP1) activity via cJun upregulation. The inhibition of p38 or AKT pathways attenuated the CD46induced MMP9 and AP1 upregulation, indicating that the promotion of MMP9 by CD46 involved activating both p38 MAPK and AKT. Functionally, the upregulation of MMP9 by CD46 translated to increased migratory and invasive capabilities of bladder cancer cells, as well as enhanced in vivo metastasis. Overall, the present study revealed a novel role for CD46 as a metastasis promoter through MMP9 activation in bladder cancers and highlighted the regulatory mechanism of CD46mediated MMP9 promotion via p38 MAPK and AKT activation.

INTRODUCTION: Bladder cancer, with a greater incidence in males than in females, requires frequent cystoscopies. We aimed to evaluate the effect of music played through noise-canceling headphones on male bladder cancer patients during follow-up cystoscopy. METHODS: A total of 160 male bladder cancer patients undergoing follow-up flexible cystoscopy were randomly divided into the noise-canceling headphones without music group and the noise-canceling headphones with music group (groups 1 and 2, respectively; n = 80 per group). The patients' clinical characteristics were examined, and objective and subjective measurements were compared before and after cystoscopy. The primary outcomes that were evaluated included the visual analog scale (VAS, 0-10) and the state-trait anxiety inventory (STAI, 20-80). Other outcomes, including vital signs and scores for assessing satisfaction and the willingness to repeat the procedure, were also examined. RESULTS: The characteristics of the patients in groups 1 and 2, and their pre-cystoscopy status, did not differ significantly. Although post-cystoscopy vital signs for the objective parameters and VAS pain scores were similar between the groups, subjective parameters were not. When compared with group 1, post-cystoscopy STAI-state scores were significantly lower in group 2, whereas patients' satisfaction scores and the willingness to repeat the procedure were significantly higher in group 2 (p = 0.002, 0.001, and 0.001, respectively). Additionally, in group 2, STAI-state scores changed significantly after the procedure when compared with before the procedure (p = 0.002). CONCLUSION: Providing music to male bladder cancer patients through noise-canceling headphones was found to reduce anxiety during cystoscopy and to improve patient satisfaction and willingness to undergo repeat cystoscopy.
RESUMEN
OBJECTIVES: To assess the effects of immunotherapy compared to chemotherapy as first- and second-line treatment of advanced or metastatic urothelial carcinoma. METHODS: Based on a published protocol, we performed a systematic search of multiple databases. Two review authors independently performed the literature selection, identified relevant studies, assessed the eligibility of studies for inclusion, and extracted data. We performed statistical analyses using a random-effects model and assessed the quality of the evidence on a per-outcome basis according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We included five randomised controlled trials and also identified seven single-arm studies. When used as first-line therapy, immunotherapy probably has little to no effect on the risk of death from any cause compared to chemotherapy (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.87-1.07; moderate-certainty evidence). immunotherapy probably has little to no effect on health-related quality of life (mean difference [MD] 4.10, 95% CI 3.83-4.37; moderate). Immunotherapy probably reduces grade 3-5 adverse events (risk ratio [RR] 0.47, 95% CI 0.29-0.75; moderate). In the second-line setting immunotherapy may reduce the risk of death from any cause (HR 0.72, 95% CI 0.63-0.81; low). Immunotherapy may have little to no effect on health-related quality of life when compared to chemotherapy (MD 4.82, 95% CI -3.11 to 12.75; low). Immunotherapy may reduce grade 3-5 adverse events (RR 0.89, 95% CI 0.81-0.97; low). CONCLUSIONS: Compared to chemotherapy, immunotherapy has little to no effect on the risk of death from any cause in a first-line setting. Nevertheless, it may reduce the risk of death from any cause when used as second-line therapy. The health-related quality of life of participants receiving first- and second-line therapy does not appear to be affected by immunotherapy. Immunotherapy probably reduces or may reduce grade 3-5 adverse events when used as first- and second-line therapy, respectively.
RESUMEN
BACKGROUND: Patients with renal cell carcinoma (RCC) have an elevated risk of chronic kidney disease (CKD) following nephrectomy. Therefore, continuous monitoring and subsequent interventions are necessary. It is recommended to evaluate renal function postoperatively. Therefore, a tool to predict CKD onset is essential for postoperative follow-up and management. METHODS: We constructed a cohort using data from eight tertiary hospitals from the Korean Renal Cell Carcinoma (KORCC) database. A dataset of 4389 patients with RCC was constructed for analysis from the collected data. Nine machine learning (ML) models were used to classify the occurrence and nonoccurrence of CKD after surgery. The final model was selected based on the area under the receiver operating characteristic (AUROC), and the importance of the variables constituting the model was confirmed using the shapley additive explanation (SHAP) value and Kaplan-Meier survival analyses. RESULTS: The gradient boost algorithm was the most effective among the various ML models tested. The gradient boost model demonstrated superior performance with an AUROC of 0.826. The SHAP value confirmed that preoperative eGFR, albumin level, and tumor size had a significant impact on the occurrence of CKD after surgery. CONCLUSIONS: We developed a model to predict CKD onset after surgery in patients with RCC. This predictive model is a quantitative approach to evaluate post-surgical CKD risk in patients with RCC, facilitating improved prognosis through personalized postoperative care.

The World Health Organization/International Society of Urological Pathology (WHO/ISUP) grading of renal cell carcinoma (RCC) is classified from grade 1-4, regardless of subtype. The National Comprehensive Cancer Network (NCCN) guidelines (2022) state that if there is an adverse pathological feature, such as grade 3 or higher RCC in stage 1 patients, more rigorous follow-up imaging is recommended. However, the RCC guidelines do not provide specific treatment or follow-up policies by tumor grade. Therefore, this study attempted to find out whether tumor grade affects survival rates in patients with metastatic RCC. The Korean Renal Cancer Study Group (KRoCS) database includes 3108 patients diagnosed with metastatic RCC between September 1992 and February 2017, with treatment methods, progression, and survival data collected from 11 tertiary hospitals. To obtain information on survival rates or causes of death, we utilized the Korea National Statistical Office database and institutional medical records. Data were accessed for research purpose on June, 2023. We then reviewed these sources to gather comprehensive and reliable data on the outcomes of our study cohort. This database was retrospectively analyzed, and out of 3108 metastatic RCC patients, 911 had been identified as WHO/ISUP grade. Grades were classified into either a low-grade (WHO/ISUP grade 1-2) or a high-grade group (WHO/ISUP grade 3-4). The patients were then analyzed related to progression and overall survival (OS). In metastatic clear cell RCC patients, the 1-year OS rate was 69.4% and the median OS was 17.0 months (15.5-18.5) followed up to 203.6 months. When comparing the patient groups, 119 low-grade and 873 high-grade cases were identified. No baseline difference was observed between the two groups, except that the high-grade group had a higher ECOG 1 ratio of 50.4% compared with 34.5% for the low-grade group (p = 0.009). There was a significant difference in OS between high-grade and low-grade groups. OS was 16.0 months (14.6-17.4) in the high-grade group and 28.0 months (21.1-34.9) in the low-grade group (p < 0.001). However, there was no difference in progression-free survival (PFS) rates with 9.0 months (8.0-10.0) for the high-grade group and 10.0 months (6.8-13.2) for the low-grade group (p = 0.377) in first-line treatment. In multivariable analysis, WHO/ISUP grade was a risk factor (HR = 1.511[1.135-2.013], p = 0.005) that influenced the OS. In conclusion, WHO/ISUP grade is a major data source that can be used as a ubiquitous marker of metastatic RCC in pre-IO era. Depending on whether the RCC is high or low grade, the follow-up schedule will need to be tailored according to grade, with higher-grade patients needing more active treatment as it can not only affect the OS in the previously known localized/locoregional recurrence but also the metastatic RCC patient.

BACKGROUND: In the United States, the rate of benign histology among resected renal tumors suspected to be malignant is increasing. We evaluated the rates in the Republic of Korea and assessed the racial effect using recent multi-institutional Korean-United States data. METHODS: We conducted a multi-institutional retrospective study of 11,529 patients (8,812 from The Republic of Korea and 2,717 from the United States) and compared the rates of benign histology between the two countries. To evaluate the racial effect, we divided the patients into Korean, Asian in the US, and Non-Asian in the US. RESULTS: The rates of benign histology and small renal masses in Korean patients were significantly lower than that in United States patients (6.3% vs. 14.3%, p < 0.001) and (≤ 4 cm, 7.6% vs. 19.5%, p < 0.001), respectively. Women, incidentaloma, partial nephrectomy, minimally invasive surgery, and recent surgery were associated with a higher rate of benign histology than others. CONCLUSIONS: In Korea, the rate of benign histology among resected renal tumors was significantly lower than that in the United States. This disparity could be caused by environmental or cultural differences rather than racial differences. Our findings suggest that re-evaluating current context-specific standards of care is necessary to avoid overtreatment.

This study was conducted to investigate potential differences in vaccine efficacy between patients undergoing palliative chemotherapy and receiving adjuvant chemotherapy. Additionally, the study proved the influence of vaccination timing on vaccine efficacy during active chemotherapy. Anti-receptor-binding domain (RBD) IgG binding antibody assays and surrogate neutralizing antibody assays were performed after BNT162b2 or mRNA-1273 vaccination in 45 solid cancer patients (23 adjuvant and 22 palliative chemotherapy) and in 24 healthy controls before vaccination (baseline), at every two to four weeks after the first (post-dose 1) and the second vaccination (post-dose 2). The levels of anti-RBD IgG and neutralizing antibodies increased significantly from baseline through post-dose 1 to post-dose 2 in all three groups. At the post-dose 1, the anti-RBD IgG and neutralizing antibody levels were significantly lower in cancer patients than in healthy controls. However, by post-dose 2, the seropositivity of anti-RBD IgG and neutralizing antibodies uniformly reached 100% across all groups, with no significant disparity in antibody levels among the three groups. Moreover, the antibody titers were not significantly different between patients with a vaccine and chemotherapy interval of more than 14 days or those with less than 14 days. This study demonstrated that after second doses of mRNA COVID-19 vaccines, humoral immune responses in patients receiving chemotherapy were comparable to those of healthy controls, regardless of whether the purpose of the anti-cancer treatment was palliative or adjuvant. Furthermore, the timing of vaccination did not affect the level of humoral immunity after the second vaccination.
RESUMEN
The incidence of gonorrhea has increased significantly in recent years in the United States, especially among sexually active twenty-year-olds. Although the incidence of gonorrhea has decreased in Korea since the early 2000s, it is still common among people in their twenties. Nucleic acid amplification test (NAAT) is the most sensitive diagnostic test for detecting gonococcal infection. Gram-staining is a simple and useful laboratory test for diagnosing symptomatic male gonococcal urethritis. Although bacterial culture can be used to detect antimicrobial susceptibility, its sensitivity is lower than that of NAAT. Treatment for uncomplicated gonorrhea infection is a single intramuscular injection of ceftriaxone 500 mg. Doxycycline (100 mg twice daily for 7 days) is added if there is a possibility of co-infection with chlamydia. If ceftriaxone is difficult to use, spectinomycin 2 g can be injected intramuscularly in Korea. Patients with gonorrhea should have repeated examinations within three months at the exposure site because of a high risk of re-infection. A person diagnosed with gonorrhea should discuss the nature of the infection, the importance of informing partners, when sexual activity can resume, and how to reduce the risk of sexually transmitted infections.

BACKGROUND: We sought to identify prognostic risk factors for one year recurrence in patient with renal cell carcinoma (RCC) after partial or radical nephrectomy. METHODS: We performed a retrospective study of 1,269 patients with RCC after partial or radical nephrectomy and diagnosed recurrence using Korean Renal Cancer Study Group (KRoCS) database between January 1991 and March 2017. Recurrence-free survival (RFS), and overall survival (OS) were calculated using the Kaplan-Meier method and multivariate Cox regression analysis were performed to evaluate independent prognostic factors for recurrence. RESULTS: The median patient age was 56 years and median follow-up period was 67 months. Multivariable analysis demonstrated BMI greater than or equal to 23 and less than 30 (vs. BMI less than 23, hazard ratio [HR]: 0.707, P = 0.020) reduced recurrence one year postoperatively. Eastern Cooperative Oncology Group performance status (ECOG PS) greater than or equal to 1 (vs. ECOG PS 0, HR: 1.548, P = 0.007), high pathological T stage (pT2 vs. pT1, HR: 2.622, P < 0.001; pT3 vs. pT1, HR: 4.256, P < 0.001; pT4 vs. pT1, HR: 4.558, P < 0.001), and tumor necrosis (vs. no tumor necrosis, HR: 2.822, P < 0.001) were independent predictive factors for early recurrence within one year in patients with RCC. Statistically significant differences on RFS and OS were found among pathological T stages (pT2 vs. pT1; pT3 vs. pT1; pT4 vs. pT1, all P < 0.001). CONCLUSION: This large multicenter study demonstrated ECOG PS greater than or equal to 1, high pathological T stage, tumor necrosis and BMI less than 23 were significant prognostic risk factors of early recurrence within one year in patients with RCC who underwent nephrectomy.

BACKGROUND: Clinical practice guidelines recommend testosterone replacement therapy (TRT) for men with sexual dysfunction and testosterone deficiency. However, TRT is commonly promoted in men without testosterone deficiency and existing trials often do not clearly report participants' testosterone levels or testosterone-related symptoms. This review assesses the potential benefits and harms of TRT in men presenting with complaints of sexual dysfunction. OBJECTIVES: To assess the effects of testosterone replacement therapy compared to placebo or other medical treatments in men with sexual dysfunction. SEARCH METHODS: We performed a comprehensive search of CENTRAL (the Cochrane Library), MEDLINE, EMBASE, and the trials registries ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform, with no restrictions on language of publication or publication status, up to 29 August 2023. SELECTION CRITERIA: We included randomized controlled trials (RCTs) in men (40 years or over) with sexual dysfunction. We excluded men with primary or secondary hypogonadism. We compared testosterone or testosterone with phosphodiesterase-5 inhibitors (PDEI5I) to placebo or PDE5I alone. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the literature, assessed the risk of bias, extracted data, and rated the certainty of evidence (CoE) according to GRADE using a minimally contextualized approach. We performed statistical analyses using a random-effects model and interpreted them according to standard Cochrane methodology. Predefined primary outcomes were self-reported erectile dysfunction assessed by a validated instrument, sexual quality of life assessed by a validated instrument, and cardiovascular mortality. Secondary outcomes were treatment withdrawal due to adverse events, prostate-related events, and lower urinary tract symptoms (LUTS). We distinguished between short-term (up to 12 months) and long-term (> 12 months) outcomes. MAIN RESULTS: We identified 43 studies with 11,419 randomized participants across three comparisons: testosterone versus placebo, testosterone versus PDE5I, and testosterone with PDE5I versus PDE5I alone. This abstract focuses on the most relevant comparison of testosterone versus placebo. Testosterone versus placebo (up to 12 months) Based on a predefined sensitivity analysis of studies at low risk of bias, and an analysis combing data from the similar International Index of Erectile Function (IIEF-EF) and IIEF-5 instruments, TRT likely results in little to no difference in erectile function assessed with the IIEF-EF (mean difference (MD) 2.37, 95% confidence interval (CI) 1.67 to 3.08; I² = 0%; 6 RCTs, 2016 participants; moderate CoE) on a scale from 6 to 30 with larger values reflecting better erectile function. We assumed a minimal clinically important difference (MCID) of greater than or equal to 4. TRT likely results in little to no change in sexual quality of life assessed with the Aging Males' Symptoms scale (MD -2.31, 95% CI -3.63 to -1.00; I² = 0%; 5 RCTs, 1030 participants; moderate CoE) on a scale from 17 to 85 with larger values reflecting worse sexual quality of life. We assumed a MCID of greater than or equal to 10. TRT also likely results in little to no difference in cardiovascular mortality (risk ratio (RR) 0.83, 95% CI 0.21 to 3.26; I² = 0%; 10 RCTs, 3525 participants; moderate CoE). Based on two cardiovascular deaths in the placebo group and an assumed MCID of 3%, this would correspond to no additional deaths per 1000 men (95% CI 1 fewer to 4 more). TRT also likely results in little to no difference in treatment withdrawal due to adverse events, prostate-related events, or LUTS. Testosterone versus placebo (later than 12 months) We are very uncertain about the longer-term effects of TRT on erectile dysfunction assessed with the IIEF-EF (MD 4.20, 95% CI -2.03 to 10.43; 1 study, 42 participants; very low CoE). We did not find studies reporting on sexual quality of life or cardiovascular mortality. We are very uncertain about the effect of testosterone on treatment withdrawal due to adverse events. We found no studies reporting on prostate-related events or LUTS. AUTHORS' CONCLUSIONS: In the short term, TRT probably has little to no effect on erectile function, sexual quality of life, or cardiovascular mortality compared to a placebo. It likely results in little to no difference in treatment withdrawals due to adverse events, prostate-related events, or LUTS. In the long term, we are very uncertain about the effects of TRT on erectile function when compared to placebo; we did not find data on its effects on sexual quality of life or cardiovascular mortality. The certainty of evidence ranged from moderate (signaling that we are confident that the reported effect size is likely to be close to the true effect) to very low (indicating that the true effect is likely to be substantially different). The findings of this review should help to inform future guidelines and clinical decision-making at the point of care.

OBJECTIVES: The population attributable fraction (PAF), an epidemiologic measure of exposures and health outcomes, can provide information on the public health impacts of exposures in populations. This study aimed to systematically summarize the PAF estimates of modifiable cancer risk factors in Korea. METHODS: This review included studies that determined PAFs of modifiable risk factors for cancer in Korea. We performed systematic searches in EMBASE, MEDLINE, Cochrane library, and Korean databases for studies published up to July 2021. Two reviewers independently screened studies for eligibility, extracted data, and performed quality assessments of the included studies. Due to high variability among the data acquisition methods and PAF estimates, we presented the results qualitatively and did not perform quantitative data synthesis. RESULTS: We reviewed 16 studies that reported the PAFs of risk factors for cancer, including smoking, alcohol consumption, obesity, and various cancer sites. We found considerable variability in the PAF estimates across exposure and cancer pairs. However, PAF estimates for smoking and respiratory cancer were consistently high in men. PAF estimates were higher in men than in women for smoking and alcohol consumption but higher in women for obesity. We found limited evidence for other exposures and cancers. CONCLUSION: Our findings may be used to prioritize and plan strategies to reduce cancer burden. We encourage further and updated assessments of cancer risk factors, including those not addressed in the studies included in this review, and their potential contributions to cancer burden to better inform strategies for cancer control.

Introduction: To investigate the effects of hepatic arterial infusion chemotherapy (HAIC) with or without systemic chemotherapy compared to systemic chemotherapy alone in patients with locally advanced hepatocellular carcinoma (HCC). Methods: Following a registered protocol (PROSPERO 2023 CRD42023386780 Available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023386780), a comprehensive search was performed using reputable databases and registries up to December 26, 2022, with no language, publication date, or status restrictions. Only randomized controlled trials (RCTs) investigating the effects of HAIC with or without systemic chemotherapy versus systemic therapy alone were included. The primary outcomes were overall survival (OS), progression-free survival (PFS), and adverse events. The secondary outcomes included the objective response rate (ORR) and disease control rate (DCR). A random-effects model was used, and the certainty of the evidence was rated using GRADE. Results: Seven RCTs involving 1,010 patients were included. All trials utilized sorafenib as the comparator. Five trials (690 patients) compared HAIC plus sorafenib to sorafenib alone, while two trials (320 patients) compared HAIC to sorafenib. The results indicate that HAIC, with or without sorafenib, may increase OS, PFS, and ORR compared with sorafenib alone. HAIC may enhance DCR, but the evidence is very uncertain. Adverse events were comparable between HAIC plus sorafenib and sorafenib alone. However, adverse events might be decreased in HAIC alone. Discussion: HAIC with or without systemic chemotherapy may improve survival outcomes and response rates of patients with HCC. Since the current body of evidence is moderate to very low, more robust randomized trials are needed to confirm the efficacy of HAIC.

RESUMEN
BACKGROUND: Immune checkpoint inhibitors are increasingly important in the treatment algorithm for locally advanced and metastatic bladder cancer. Numerous ongoing studies are investigating these agents as first- and second-line therapies, both alone and in combination with chemotherapy or in a maintenance therapy setting. OBJECTIVES: To assess the effects of immune checkpoint inhibitors compared to chemotherapy as first- and second-line treatment of advanced or metastatic urothelial carcinoma. SEARCH METHODS: We performed a comprehensive search including the Cochrane Library, MEDLINE, Embase, three other databases, several trial registers, other sources of gray literature, and conference proceedings, with no restrictions on language of publication. We limited the search period to run from 2000 until August 2022. SELECTION CRITERIA: We included randomized controlled trials (RCTs) using immunotherapy versus chemotherapy and would have considered non-randomized trials in the absence of randomized trial data. Participants had locally advanced inoperable (cT4b or N+, or both) or metastatic (M1) (or both) urothelial carcinoma of the bladder or upper urinary tract. We excluded studies of people in whom immunotherapy was used in combination with chemotherapy or in a surveillance setting. DATA COLLECTION AND ANALYSIS: Two review authors independently classified studies for inclusion and abstracted data from included studies. We performed statistical analyses using a random-effects model and interpreted them according to the Cochrane Handbook for Systematic Reviews of Interventions. We used GRADE guidance to rate the certainty of evidence on a per-outcome basis. MAIN RESULTS: We included five RCTs and identified seven single-armed studies. The RCTs included 3572 participants comparing immunotherapy versus chemotherapy for the treatment of locally advanced and metastatic bladder cancer. First-line therapy Immunotherapy probably has little to no effect on the risk of death from any cause when used as first-line therapy compared to chemotherapy (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.87 to 1.07; I2 = 0%; 3 studies, 2068 participants; moderate-certainty evidence). This corresponds to 750 deaths per 1000 participants with chemotherapy and 11 fewer (45 fewer to 26 more) deaths per 1000 participants with immunotherapy at 36 months. Immunotherapy probably has little to no effect on health-related quality of life (mean difference (MD) 4.10, 95% CI 3.83 to 4.37; 1 study, 393 participants; moderate-certainty evidence), when assuming a minimal clinically important difference (MCID) of at least 6 points (using the Functional Assessment of Cancer Therapy - Bladder [FACT-BL] tool; scale 0 to 156 with higher scores representing better quality of life). Immunotherapy probably reduces adverse events grade 3 to 5 (RR 0.47, 95% CI 0.29 to 0.75; I2 = 97%; 3 studies, 2046 participants; moderate-certainty evidence). This corresponds to 908 grade 3 to 5 adverse events per 1000 participants with chemotherapy, with 481 fewer (644 fewer to 227 fewer) grade 3 to 5 adverse events per 1000 participants with immunotherapy. We found no evidence for the outcome time to death from bladder cancer. Immunotherapy probably increases the risk of time to disease progression (HR 1.33, 95% CI 1.17 to 1.50; I2 = 0%; 2 studies, 1349 participants; moderate-certainty evidence). This corresponds to 660 events per 1000 participants with chemotherapy and 102 more (57 more to 152 more) events per 1000 participants with immunotherapy at 36 months. Immunotherapy may reduce discontinuations due to adverse effects (RR 0.47, 95% CI 0.20 to 1.10; I2 = 94%; 3 studies, 2046 participants; low-certainty evidence). This corresponds to 338 discontinuations per 1000 participants with chemotherapy and 179 fewer (271 fewer to 34 more) discontinuations per 1000 participants with immunotherapy. Second-line therapy Immunotherapy may reduce the risk of death from any cause when used as second-line therapy (HR 0.72, 95% CI 0.63 to 0.81; I2 = 0%; 2 studies, 1473 participants; low-certainty evidence). This corresponds to 920 deaths per 1000 participants with chemotherapy (vinflunine, paclitaxel, docetaxel) and 59 fewer (95 fewer to 28 fewer) deaths per 1000 participants with immunotherapy at 36 months. Immunotherapy may have little to no effect on health-related quality of life when compared to chemotherapy (MD 4.82, 95% CI -3.11 to 12.75; I2 = 85%; 2 studies, 727 participants; low-certainty evidence), assuming an MCID of at least 10 points (using the EORTC QLQ tool; scale 0 to 100 with higher scores representing better quality of life). Immunotherapy may reduce adverse events grade 3 to 5 in participants undergoing second-line therapy (RR 0.89, 95% CI 0.81 to 0.97; I2 = 9%; 2 studies, 1423 participants; low-certainty evidence). This corresponds to 630 grade 3 to 5 adverse events per 1000 participants with chemotherapy and 76 fewer (126 fewer to 25 fewer) grade 3 to 5 adverse events per 1000 participants with immunotherapy. We found no evidence for the outcome of time to death from bladder cancer. We are very uncertain if immunotherapy reduces the risk of disease progression (HR 0.99, 95% CI 0.84 to 1.16; I2 = 0%; 2 studies, 1473 participants; very low-certainty evidence). Immunotherapy may reduce discontinuations due to adverse events in participants undergoing second-line therapy (RR 0.35, 95% CI 0.17 to 0.72; I2 = 69%; 2 studies, 1473 participants; low-certainty evidence). This corresponds to 110 discontinuations per 1000 participants with chemotherapy and 72 fewer (91 fewer to 31 fewer) discontinuations per 1000 participants with immunotherapy. AUTHORS' CONCLUSIONS: Compared to chemotherapy, immunotherapy for treating advanced or metastatic urothelial carcinoma probably has little to no effect on the risk of death from any cause when used as first-line therapy. Still, it may reduce the risk of death from any cause when used as second-line therapy. Health-related quality of life for participants receiving first- and second-line therapy does not appear to be affected by immunotherapy. Immunotherapy probably reduces or may reduce adverse events grade 3 to 5 when used as first- and second-line therapy, respectively.

BACKGROUND: Peyronie's disease is a condition that results in the development of penile plaques that can lead to penile curvature, pain, and erectile dysfunction, making sexual activity difficult. A number of non-surgical interventions exist to improve this condition, which include topical and injection agents as well as mechanical methods; however, their effectiveness remains uncertain. We performed this review to determine the effects of these non-surgical treatments. OBJECTIVES: To assess the effects of non-surgical therapies compared to placebo or no treatment in individuals with Peyronie's disease. SEARCH METHODS: We performed a comprehensive search using multiple databases (the Cochrane Library, MEDLINE, Embase, Scopus, Google Scholar, and Web of Science), trials registries, other sources of grey literature, and conference proceedings, up to 23 September 2022. We applied no restrictions on publication language or status. SELECTION CRITERIA: We included trials in which men with Peyronie's disease were randomized to undergo non-surgical therapies versus placebo or no treatment for penile curvature and sexual function. DATA COLLECTION AND ANALYSIS: Two of four review authors, working in pairs, independently classified studies and abstracted data from the included studies. Primary outcomes were: patient-reported ability to have intercourse, quality of life, and treatment-related adverse effects. Secondary outcomes were: degree of penile curvature, discontinuation from treatment (for any reason), subjective patient-reported change in penile curvature, and improvement in penile pain. We performed statistical analyses using a random-effects model. We rated the certainty of evidence (CoE) according to the GRADE approach. MAIN RESULTS: Our search identified 1288 relevant references of which we included 18 records corresponding to 14 unique randomized controlled trials (RCTs) with 1810 men. These informed 10 distinct comparisons with relevant outcome data that were mostly extracted from single trials. In this abstract, we focus only on the most clinically relevant comparisons for the three primary outcomes and also include the outcome of degree penile curvature. Injectional collagenase (short-term): We found no short-term evidence on injectional collagenase for patients' self-reported ability to have intercourse and treatment-related adverse effects compared to placebo injection. Injectional collagenase may result in little to no difference in quality of life (scale 0 to 20 with lower scores indicating better quality of life; mean difference (MD) 1.8 lower, 95% confidence interval (CI) -3.58 to -0.02; 1 study, 134 participants; low CoE) and there may be little to no effect on the degree of penile curvature (MD 10.90 degrees less, 95% CI -16.24 to -5.56; 1 study, 136 participants; low CoE). Injectional collagenase (long-term): We also found no long-term evidence on injectional collagenase for patients' self-reported ability to have intercourse compared to placebo injection. It likely results in little to no effect on quality of life (MD 1.00 lower, 95% CI -1.60 to -0.40; 1 study, 612 participants; moderate CoE). Treatment-related adverse effects are likely increased (risk ratio (RR) 2.32, 95% CI 1.98 to 2.72; 1 study, 832 participants; moderate CoE). Injectional collagenase likely results in little to no change in the degree of penile curvature (MD 6.90 degrees less, 95% CI -9.64 to -4.14; 1 study, 612 participants; moderate CoE). Injectional verapamil (short-term): We are very uncertain how injectional verapamil may affect patients' self-reported ability to have intercourse compared to placebo injection short-term (RR 7.00, 95% CI 0.43 to 114.70; 1 study, 14 participants; very low CoE). We found no evidence for the outcome of quality of life. We are very uncertain how injectional verapamil may affect treatment-related adverse effects (RR not estimable; 1 study, 14 participants; very low CoE). Similarly, we are very uncertain how injectional verapamil may affect degree of penile curvature (MD -1.86, 95% CI -10.39 to 6.67; 1 study, 14 participants; very low CoE). We found no long-term data for any outcome. Extracorporeal shock wave treatment (ESWT) (short-term): We are very uncertain how ESWT affects patients' self-reported ability to have intercourse short-term (RR 1.60, 95% CI 0.71 to 3.60; 1 study, 26 participants; very low CoE). ESWT may result in little to no difference in quality of life (MD 3.10, 95% CI 1.57 to 4.64; 2 studies, 130 participants; low CoE). We are very uncertain if ESWT has an effect on treatment-related adverse effects (RR 2.73, 95% CI 0.74 to 10.14; 3 studies, 166 participants; very low CoE). ESWT may result in little to no difference in the degree of penile curvature compared to placebo (RR -2.84, 95% -7.35 to 1.67; 3 studies, 166 participants; low CoE). We found no long-term data for any outcome. Penile traction therapy (short-term): We found no evidence for whether penile traction compared to no treatment affects patients' self-reported ability to have intercourse. We are very uncertain how traction therapy may affect quality of life (MD 1.50 lower, 95% CI -3.42 to 0.42; 1 study, 90 participants; very low CoE). We are also very uncertain how traction therapy may affect treatment-related adverse effects (RR not estimable; 1 study, 90 participants; very low CoE) and how it affects the degree of curvature (MD 7.40 degrees less, 95% CI -11.18 to -3.62; 1 study, 89 participants; very low CoE). We found no long-term data for any outcome. AUTHORS' CONCLUSIONS: There is little evidence supporting the effectiveness of most non-surgical treatments for Peyronie's disease. Existing trials are mostly of poor methodological quality and/or fail to address patient-centered outcomes. Injectional collagenase appears to have some effectiveness; however, many individuals may not experience the improvement as clinically relevant, and this comes with the risk of increased adverse events. There is a critical need for better non-surgical treatment options for men with Peyronie's disease.
ANTECEDENTES: La enfermedad de Peyronie es una afección que da lugar al desarrollo de placas en el pene que pueden provocar curvatura peneana, dolor y disfunción eréctil, dificultando la actividad sexual. Existen varias intervenciones no quirúrgicas para mejorar esta afección, que incluyen agentes tópicos e inyectables, así como métodos mecánicos; sin embargo, su eficacia aún es incierta. Esta revisión se realizó para determinar los efectos de estos tratamientos no quirúrgicos. OBJETIVOS: Evaluar los efectos de los tratamientos no quirúrgicos en comparación con placebo o ningún tratamiento en individuos con enfermedad de Peyronie. MÉTODOS DE BÚSQUEDA: Se realizó una búsqueda exhaustiva en múltiples bases de datos (la Biblioteca Cochrane, MEDLINE, Embase, Scopus, Google Scholar y Web of Science), en registros de ensayos, otras fuentes de literatura gris y resúmenes de congresos, hasta el 23 de septiembre de 2022. No se impusieron restricciones respecto al idioma ni el estado de publicación. CRITERIOS DE SELECCIÓN: Se incluyeron ensayos en los que se asignó al azar a hombres con enfermedad de Peyronie a someterse a tratamientos no quirúrgicos versus placebo o ningún tratamiento para la curvatura del pene y la función sexual. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Dos de los cuatro autores de la revisión, trabajando en pareja, clasificaron de forma independiente los estudios y resumieron los datos de los estudios incluidos. Los desenlaces principales fueron: capacidad para mantener relaciones sexuales autoinformada por el paciente, calidad de vida y efectos adversos relacionados con el tratamiento. Los desenlaces secundarios fueron: grado de curvatura del pene, interrupción del tratamiento (por cualquier motivo), cambio subjetivo de la curvatura del pene autoinformado por el paciente y mejoría del dolor del pene. Se realizaron análisis estadísticos con un modelo de efectos aleatorios. La certeza de la evidencia se calificó según el método GRADE. RESULTADOS PRINCIPALES: La búsqueda identificó 1288 referencias pertinentes, de las cuales se incluyeron 18 registros correspondientes a 14 ensayos controlados aleatorizados (ECA) individuales con 1810 hombres. Éstos informaron 10 comparaciones distintas con datos de desenlaces relevantes que se extrajeron en su mayoría de ensayos individuales. Este resumen se centra solo en las comparaciones clínicamente más relevantes para los tres desenlaces principales y también se incluye el desenlace de grado de curvatura peneana. Colagenasa inyectable (a corto plazo): No se encontró evidencia a corto plazo de la colagenasa inyectable, en comparación con la inyección placebo, en la capacidad autoinformada por los pacientes de tener relaciones sexuales ni en los efectos adversos relacionados con el tratamiento. La colagenasa inyectable podría dar lugar a poca o ninguna diferencia en la calidad de vida (escala de 0 a 20 con puntuaciones más bajas que indican mejor calidad de vida; diferencia de medias [DM] 1,8 menor; intervalo de confianza [IC] del 95%: 3,58 a 0,02; un estudio, 134 participantes; evidencia de certeza baja) y podría haber poco o ningún efecto en el grado de curvatura del pene (DM 10,90 grados menos; IC del 95%: 16,24 a 5,56; un estudio, 136 participantes; evidencia de certeza baja). Colagenasa inyectable (a largo plazo): Tampoco se encontró evidencia a largo plazo sobre la colagenasa inyectable en la capacidad autoinformada por los pacientes de tener relaciones sexuales en comparación con la inyección placebo. Es probable que tenga un efecto escaso o nulo sobre la calidad de vida (DM 1,00 inferior; IC del 95%: 1,60 a 0,40; un estudio, 612 participantes; evidencia de certeza moderada). Es probable que aumenten los efectos adversos relacionados con el tratamiento (razón de riesgos [RR] 2,32; IC del 95%: 1,98 a 2,72; un estudio, 832 participantes; evidencia de certeza moderada). La colagenasa inyectable probablemente provoca poco o ningún cambio en el grado de curvatura del pene (DM 6,90 grados menos; IC del 95%: 9,64 a 4,14; un estudio, 612 participantes; evidencia de certeza moderada). Verapamilo inyectable (a corto plazo): No está muy claro cómo el verapamilo inyectable podría afectar la capacidad autoinformada por los pacientes de tener relaciones sexuales en comparación con la inyección placebo a corto plazo (RR 7,00; IC del 95%: 0,43 a 114,70; un estudio, 14 participantes; evidencia de certeza muy baja). No se encontró evidencia del desenlace de calidad de vida. No se sabe con certeza cómo podría afectar el verapamilo inyectable los efectos adversos relacionados con el tratamiento (RR no estimable; un estudio, 14 participantes; evidencia de certeza muy baja). Del mismo modo, es muy incierto cómo el verapamilo inyectable podría afectar el grado de curvatura peneana (DM 1,86; IC del 95%: 10,39 a 6,67; un estudio, 14 participantes; evidencia de certeza muy baja). No se encontraron datos a largo plazo para ningún desenlace. Tratamiento con ondas de choque extracorpóreas (OCE) (a corto plazo): No está muy claro cómo el tratamiento con OCE afecta la capacidad autoinformada por los pacientes de mantener relaciones sexuales a corto plazo (RR 1,60; IC del 95%: 0,71 a 3,60; un estudio, 26 participantes; evidencia de certeza muy baja). El tratamiento con OCE podría dar lugar a poca o ninguna diferencia en la calidad de vida (DM 3,10; IC del 95%: 1,57 a 4,64; dos estudios, 130 participantes; evidencia de certeza baja). No está muy claro si el tratamiento con OCE influye en los efectos adversos relacionados con el tratamiento (RR 2,73; IC del 95%: 0,74 a 10,14; tres estudios, 166 participantes; evidencia de certeza muy baja). El tratamiento con OCE podría dar lugar a poca o ninguna diferencia en el grado de curvatura peneana en comparación con el placebo (RR 2,84; 95%: 7,35 a 1,67; tres estudios, 166 participantes; evidencia de certeza baja). No se encontraron datos a largo plazo para ningún desenlace. Terapia de tracción peneana (a corto plazo): No se encontró evidencia de si la tracción peneana comparada con ningún tratamiento afecta la capacidad autoinformada por los pacientes de tener relaciones sexuales. No se sabe con certeza cómo podría afectar la terapia de tracción la calidad de vida (DM 1,50 inferior; IC del 95%: 3,42 a 0,42; un estudio, 90 participantes; evidencia de certeza muy baja). Tampoco se sabe con certeza cómo podría afectar la terapia de tracción los efectos adversos relacionados con el tratamiento (RR no estimable; un estudio, 90 participantes; evidencia de certeza muy baja) ni cómo afecta el grado de curvatura (DM 7,40 grados menos; IC del 95%: 11,18 a 3,62; un estudio, 89 participantes; evidencia de certeza muy baja). No se encontraron datos a largo plazo para ningún desenlace. CONCLUSIONES DE LOS AUTORES: Existe poca evidencia que respalde la eficacia de la mayoría de los tratamientos no quirúrgicos para la enfermedad de Peyronie. Los ensayos existentes son en su mayoría de baja calidad metodológica y no abordan los desenlaces centrados en el paciente. La colagenasa inyectable parece tener cierta eficacia; sin embargo, es posible que muchas personas no experimenten una mejoría clínicamente relevante, lo que conlleva el riesgo de un aumento de los eventos adversos. Existe una necesidad imperiosa de mejores opciones terapéuticas no quirúrgicas para los hombres con enfermedad de Peyronie.

INTRODUCTION: The COVID-19 pandemic has resulted in many cases of infection and deaths worldwide. Patients with cancer are a high-risk group for COVID-19-related death. However, a systematic summary of the prognostic factors related to mortality in these patients is limited. We systematically summarise the evidence on the prognostic factors of mortality in patients with pre-existing cancer, infected with COVID-19. METHODS AND ANALYSIS: We will address the prognostic factors for mortality, including cohort studies of adult patients with cancer infected with COVID-19. We will search MEDLINE, Embase and Cochrane Central Libraries for data from December 2019 to the present day. The prognostic factors for mortality include general, cancer-related and clinical characteristics. We will not limit the COVID-19 severity, cancer type and follow-up period of the included studies. Two reviewers will independently and in duplicate conduct reference screening, data abstraction and risk of bias assessment. We will perform a random-effect meta-analysis to calculate the pooled relative effect estimates for each prognostic factor of mortality. We will assess the risk of bias for each included study and rate the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. This study will provide information about high-risk groups for mortality in patients with cancer infected with COVID-19. ETHICS AND DISSEMINATION: This study will use only the published references and would not need to obtain ethical approval. We will disseminate our study findings through a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023390905.

PURPOSE: Recent studies have highlighted increasing infectious complications due to fluoroquinolone (FQ)-resistant organisms in men undergoing transrectal ultrasound-guided prostate biopsy (TRUSPB). This study investigated whether fosfomycin (FM)-based antibiotic prophylaxis reduces infections after TRUSPB and identified risk factors for infective complications. MATERIALS AND METHODS: A multicenter study was conducted in the Republic of Korea from January 2018 to December 2021. Patients undergoing prostate biopsy with FQ or FM-based prophylaxis were included. The primary outcome was the post-biopsy infectious complication rate after FQ (group 1) or FM-based antibiotic prophylaxis with FM alone (group 2) or FQ and FM (group 3). Risk factors for infectious complications after TRUSPB were secondary outcomes. RESULTS: Patients (n=2,595) undergoing prostate biopsy were divided into three groups according to the type of prophylactic antibiotics. Group 1 (n=417) received FQ before TRUSPB. Group 2 (n=795) received FM only and group 3 (n=1,383) received FM and FQ before TRUSPB. The overall post-biopsy infectious complication rate was 1.27%. The infectious complication rates were 2.4%, 1.9%, and 0.5% in groups 1, 2, and 3, respectively (p=0.002). In multivariable analysis, predictors of post-biopsy infectious complications included an association with health care utilization (adjusted odds ratio [OR], 4.66; 95% confidence interval [CI], 1.74-12.4; p=0.002) and combination antibiotic prophylaxis (FQ and FM) (adjusted OR, 0.26; 95% CI, 0.09-0.69; p=0.007). CONCLUSIONS: In comparison with monotherapy with FM or FQ, combination antibiotic prophylaxis (FQ and FM) showed a lower rate of infectious complications after TRUSPB. Utilization of health care was an independent risk factor for infectious complications after TRUSPB.

Background and Objectives: To assess the effects of fosfomycin compared with other antibiotics as a prophylaxis for urinary tract infections (UTIs) in men undergoing transrectal prostate biopsies. Materials and Methods: We searched multiple databases and trial registries without publication language or status restrictions until 4 January 2022. Parallel-group randomized controlled trials (RCTs) and non-randomized studies (NRS) were included. The primary outcomes were febrile UTI, afebrile UTI, and overall UTI. We used GRADE guidance to rate the certainty of evidence of RCTs and NRSs. The protocol was registered with PROSPERO (CRD42022302743). Results: We found data on five comparisons; however, this abstract focuses on the primary outcomes of the two most clinically relevant comparisons. Regarding fosfomycin versus fluoroquinolone, five RCTs and four NRSs with a one-month follow-up were included. Based on the RCT evidence, fosfomycin likely resulted in little to no difference in febrile UTIs compared with fluoroquinolone. This difference corresponded to four fewer febrile UTIs per 1000 patients. Fosfomycin likely resulted in little to no difference in afebrile UTIs compared with fluoroquinolone. This difference corresponded to 29 fewer afebrile UTIs per 1000 patients. Fosfomycin likely resulted in little to no difference in overall UTIs compared with fluoroquinolone. This difference corresponded to 35 fewer overall UTIs per 1000 patients. Regarding fosfomycin and fluoroquinolone combined versus fluoroquinolone, two NRSs with a one- to three-month follow-up were included. Based on the NRS evidence, fosfomycin and fluoroquinolone combined may result in little to no difference in febrile UTIs compared with fluoroquinolone. This difference corresponded to 16 fewer febrile UTIs per 1000 patients. Conclusions: Compared with fluoroquinolone, fosfomycin or fosfomycin and fluoroquinolone combined may have a similar prophylactic effect on UTIs after a transrectal prostate biopsy. Given the increasing fluoroquinolone resistance and its ease to use, fosfomycin may be a good option for antibiotic prophylaxis.

PURPOSE: We evaluate the reporting of the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to rating the certainty of evidence in systematic reviews published in the urological literature. MATERIALS AND METHODS: Based on a predefined protocol, we identified all systematic reviews published in 5 major urological journals from 1998 to 2021 that reported the use of GRADE. Two authors performed study selection and data abstraction independently to assess reporting in accordance with established criteria for applying GRADE. RESULTS: We included 68 of 522 (13.0%) systematic reviews that reported the use of GRADE; the first was published in 2009. Approximately half were published between 2009-2018 (n=36) and the other half between 2019-2021 (n=32). Oncology (24; 35.3%) was the most common clinical topic, and the authors were mostly based in Europe (34; 50%). In their abstract, less than half of all systematic reviews (32; 47.1%) provided any certainty of evidence rating. Only 41 (60.3%) included a tabular result summary in the format of a summary of findings table (24; 35.3%) or evidence profile (17; 25.0%). Few (35.3%) addressed the GRADE certainty of evidence rating in the discussion section. Reporting did not improve over time when comparing the 2 time periods. CONCLUSIONS: Whereas GRADE is increasingly being applied for rating the certainty of evidence, systematic reviews published in the urological literature frequently have not followed established criteria for applying or using GRADE. There is a need for better training of authors and editors, as well as for a GRADE reporting checklist for systematic review authors.

We developed a novel prediction model for recurrence and survival in patients with localized renal cell carcinoma (RCC) after surgery and a novel statistical method of machine learning (ML) to improve accuracy in predicting outcomes using a large Asian nationwide dataset, updated KOrean Renal Cell Carcinoma (KORCC) database that covered data for a total of 10,068 patients who had received surgery for RCC. After data pre-processing, feature selection was performed with an elastic net. Nine variables for recurrence and 13 variables for survival were extracted from 206 variables. Synthetic minority oversampling technique (SMOTE) was used for the training data set to solve the imbalance problem. We applied the most of existing ML algorithms introduced so far to evaluate the performance. We also performed subgroup analysis according to the histologic type. Diagnostic performances of all prediction models achieved high accuracy (range, 0.77-0.94) and F1-score (range, 0.77-0.97) in all tested metrics. In an external validation set, high accuracy and F1-score were well maintained in both recurrence and survival. In subgroup analysis of both clear and non-clear cell type RCC group, we also found a good prediction performance.

BACKGROUND: There is few of optimal management guideline in elderly patients with renal cell carcinoma (RCC). To compare the survival outcomes of octogenarian RCC group and younger RCC group after surgery using nationwide multi-institutional database. METHODS: A total of 10,068 patients who underwent surgery for RCC were included in the current retrospective, multi-institutional study. A propensity score matching (PSM) analysis was conducted to control other confounding factors in analyzing survival outcomes of octogenarian and younger group RCCs. Kaplan-Meier curve analysis to calculate the survival estimates for cancer-specific survival (CSS) and overall survival (OS), and multivariate Cox-proportional hazard regression analyses to evaluate the significant variables associated with the survival outcomes were also performed. RESULTS: Both groups were well-balanced in all baseline characteristics. In a total cohort, Kaplan-Meier survival analysis showed a significantly decreased 5-year and 8-year CSS and OS in the octogenarian group compared with the younger group. However, in a PSM cohort, no significant differences were evident between the two groups in terms of CSS (5-year, 87.3% vs. 87.0%; 8-year, 82.2% vs. 78.9%, respectively, log-rank test, p = 0.964). In addition, age ≥ 80 years (HR, 1.199; 95% CI, 0.497-2.896, p = 0.686) was not a significant prognostic factor of CSS in a PSM cohort. CONCLUSIONS: The octogenarian RCC group after surgery had comparable survival outcomes compared with younger group after PSM analysis. For the life expectancy of octogenarian is getting longer, active treatment is considerable in patients with good performance status.
