Background: Blood and urine biomarkers have been associated with urologic tumors, but their causal relationship with urologic tumors is unclear. Methods: We performed a bidirectional Mendelian randomization (MR) analysis of the association between 35 blood and urine biomarkers and urological tumors in our discovery cohort. A Bayesian weighting approach was used to validate the positive results identified in the discovery cohort, and steiger filtering analysis was used to distinguish causality from reverse causality. Bayesian colocalization analysis was used to analyze which single nucleotide polymorphisms (SNPs) specifically co-located between the positive blood and urine biomarkers and the disease phenotypes were driven, and MR-positive results from the discovery cohort and the validation cohort were combined using the MR-meta method. Results: Several blood and urine biomarkers were found to be significantly and causally associated with urologic cancers. Notably, calcium (OR: 1.34, 95%CI 1.10–1.63, P = 0.0040) and sex hormone-binding globulin (SHBG) (OR: 0.81, 95%CI 0.70–0.95, P = 0.0092) were associated with bladder cancer; gamma glutamyl transferase (GGT) (OR: 0.91, 95%CI 0.83–0.99, P = 0.0209), lipoprotein A (Lp(a)) (OR: 1.12, 95%CI 1.01–1.24, P = 0.0399), and insulinlike growth factor 1 (IGF 1) (OR: 1.10, 95%CI 1.01–1.20, P = 0.0220) were linked to prostate cancer (PCa); non albumin protein (OR: 0.78, 95%CI 0.65–0.93, P = 0.0065) and total protein (OR: 0.80, 95%CI 0.64–0.99, P = 0.0380) were linked to renal cancer; and apolipoprotein A (Apo-A) (OR: 0.56, 95%CI 0.32–0.98, P = 0.0426) and urate (OR:1.89, 95%CI 1.03–3.47, P = 0.0399) were associated with renal pelvis cancer. These associations were validated in an independent cohort, with GGT, IGF 1, and Lp(a) being consistently linked to PCa. Conclusion: This study identified significant biomarkers associated with urological cancers in blood and urine. These include GGT, IGF 1, and Lp(a), which are strong biomarkers for PCa. In addition, the findings of this study provide evidence for a handful of risk and protective factors for the development of urologic cancers. [ABSTRACT FROM AUTHOR]

Abstract Background The aim of this study was to evaluate data over the past 25 years to assess the prevalence of the virus in patients with bladder cancer and to evaluate the association between human papillomavirus (HPV) and bladder cancer risk. Main text Major databases were searched for published studies from October 1995 to May 2022. The present study evaluated the prevalence of HPV in patients with bladder cancer and the prevalence according to patients' ethnicity. The incidence of HPV in bladder cancer patients varies widely, ranging from complete absence of the virus in tissues to 64.6%. The meta-analysis was performed using Meta-Essentials_1.5 software. Begg’s and Egger’s methods were used to assess publication bias. Cochran’s Q test was used to assess heterogeneity and the I2 index was employed for calculating the variation in the pooled estimations. Conclusions A weak association of HPV infection with the risk of bladder cancer was found. The risk of bladder cancer with HPV infection has clear ethnic characteristics and is statistically significant in Arabs and Asians.

• Nanocarriers (NCs), including lipid-based, nanoparticle albumin-bound, and polymeric varieties, have been explored in urologic cancers. • Phase I and II trials in bladder, kidney, and prostate cancers have primarily focused on safety and efficacy, with no reported phase III trials. • While nab-paclitaxel and liposomal doxorubicin are commonly used NCs in other cancer settings, their suboptimal efficacy prevents clinical use in urologic cancers. • Ongoing research in the field is investigating more advanced technologies like protein-targeting NCs and pH-controlled release particles, with some advancing to pre-clinical and phase I trials. Nanocarriers (NCs) are a form of nanotechnology widely investigated in cancer treatment to improve the safety and efficacy of systemic therapies by increasing tumor specificity. Numerous clinical trials have explored the use of NCs in urologic cancers since the approval of the first NCs for cancer treatment over 20 years ago. The objective of this systematic review is to examine the effectiveness and safety of NCs in treating urological cancers. This paper summarizes the state of the field by investigating peer-reviewed, published results from 43 clinical trials involving the use of NCs in bladder, prostate, and kidney cancer patients with a focus on safety and efficacy data. Among the 43 trials, 16 were phase I, 20 phase II, and 4 phase I/II. No phase III trials have been reported. While both novel and classic NCs have been explored in urologic cancers, NCs already approved for the treatment of other cancers were more widely represented. Trials in prostate cancer and mixed trials involving both urologic and non-urologic cancer patients were the most commonly reported trials. Although NCs have demonstrable efficacy with adequate safety in non-urologic cancer patient populations, current clinical stage NC options appear to be less beneficial in the urologic cancer setting. For example, nab-paclitaxel and liposomal doxorubicin have proven ineffective in the treatment of urologic cancers despite successes in other cancers. However, several ongoing pre-clinical studies using targeted and locally applied improved NCs may eventually improve their utility. [ABSTRACT FROM AUTHOR]

Purpose: US states eased licensing restrictions on telemedicine during the COVID-19 pandemic, allowing interstate use. As waivers expire, optimal uses of telemedicine must be assessed to inform policy, legislation, and clinical care. We assessed whether telemedicine visits provided the same patient experience as in-person visits, stratified by in- vs out-of-state residence, and examined the financial burden. Materials and Methods: Patients seen in person and via telemedicine for urologic cancer care at a major regional cancer center received a survey after their first appointment (August 2019eJune 2022) on satisfaction with care, perceptions of communication during their visit, travel time, travel costs, and days of work missed. Results: Surveys were completed for 1058 patient visits (N[178 in-person, N[880 telemedicine). Satisfaction rates were high for all visit types, both interstate and instate care (mean score 60.1-60.8 [maximum 63], P > .05). More patients convening interstate telemedicine would repeat that modality (71%) than interstate in-person care (61%) or in-state telemedicine (57%). Patients receiving interstate care had significantly higher travel costs (median estimated visit costs $200, IQR $0-$800 vs median $0, IQR $0-$20 for in-state care, P < .001); 55% of patients receiving interstate in-person care required plane travel and 60% required a hotel stay. Conclusions: Telemedicine appointments may increase access for rural-residing patients with cancer. Satisfaction outcomes among patients with urologic cancer receiving interstate care were similar to those of patients cared for in state; costs were markedly lower. Extending interstate exemptions beyond COVID-19 licensing waivers would permit continued delivery of high-quality urologic cancer care to rural-residing patients. [ABSTRACT FROM AUTHOR]

Abstract Objective To investigate the association between metabolic syndrome (MetS) and its components and the risk of developing urologic cancers. Methods This study included 101,510 observation subjects from May 2006 to December 2007. The subjects received questionnaires and were subjected to clinical and laboratory examinations to collect data on baseline population characteristics, waist circumference (WC), blood pressure (BP), blood glucose, blood lipids, lifestyle, and past disease history. Finally, follow-up was conducted from the date of recruitment to December 31, 2019. Cox proportional hazards modelling was applied to analyze the association between MetS and its components and the risk of developing urologic cancers. Results A total of 97,975 observation subjects met the inclusion criteria. The cumulative follow-up period included 1,209,178.65 person-years, and the median follow-up time was 13.03 years. During the follow-up period, 485 cases of urologic cancers (165 cases of kidney cancer, 134 cases of prostate cancer, 158 cases of bladder cancer, and 28 cases of other urologic cancers) were diagnosed. The log-rank test results for the cumulative incidences of urologic cancer, kidney cancer, and prostate cancer indicated significant (P

It is quite unusual to have numerous primary malignant tumors at the same time in the same patient. These cancers are classified as metachronous or synchronous. The occurrence of synchronous urologic tumors poses diagnostic and treatment challenges and has always been a subject of controversy in the clinical decision-making process. Unfortunately, no clear standardized management protocols for these patients exist. Therefore, diagnosis and treatment may be difficult, especially with few resources. We present a 75-year-old man with simultaneous prostate and kidney cancers successfully treated at our center. This is one of the rare cases in the English literature with two primary urologic cancers. [ABSTRACT FROM AUTHOR]

Background: To improve the quality and cost-effectiveness of care, cancer patients can obtain a second medical opinion on their treatment. Validation of the diagnostic procedure (e.g., imaging), diagnosis, and treatment recommendation allows oncological therapy to be applied in a more targeted way, optimizing interdisciplinary care. This study describes patients who received second opinions at the Comprehensive Cancer Center for Erlangen–Nuremberg metropolitan area in Germany over a 6-year period, as well as the amount of time spent on second-opinion counseling. Methods: This prospective, descriptive, single-center observational study included 584 male and female cancer patients undergoing gynecological, urologic, or general surgery who sought a second medical opinion. The extent to which the first opinion complied with standard guidelines was assessed solely descriptively. Results: The first opinion was in accordance with the guidelines and complete in 54.5% of the patients, and guideline compliant but incomplete in 13.2%. The median time taken to form a second opinion was 225 min, and the cancer information service was contacted by patients an average of eight times. Conclusions: The initial opinion was guideline compliant and complete in every second case. Without a second opinion, the remaining patients would have been denied a guideline-compliant treatment recommendation. Obtaining a second opinion gives patients an opportunity to receive a guideline-compliant treatment recommendation and enables them to benefit from newer, individualized therapeutic approaches in clinical trials. Establishing patient-initiated second opinions via central contact points appears to be a feasible option for improving guideline compliance. [ABSTRACT FROM AUTHOR]

During the follow-up period, 485 cases of urologic cancers (165 cases of kidney cancer, 134 cases of prostate cancer, 158 cases of bladder cancer, and 28 cases of other urologic cancers) were diagnosed. The log-rank test results for the cumulative incidences of urologic cancer, kidney cancer, and prostate cancer indicated significant (P < 0.01) differences between the MetS and non-MetS groups (0.70% vs. 0.48%, 0.27% vs. 0.15%, and 0.22% vs. 0.13%, respectively). Compared to the non-MetS group, the risk of developing urologic [HR (95% CI) = 1.29 (1.08–1.55)], kidney [HR (95% CI) = 1.74 (1.28–2.37)], and prostate [HR (95% CI) = 1.47 (1.04–2.07)] cancers was significantly higher in the MetS group. In the MetS group, elevated BP increased the risk of developing of urologic cancer [HRs (95% CI) = 1.35 (1.10–1.66)] and kidney cancer [HR (95% CI) = 1.74 (1.21–2.51)], while central obesity increased the risk of developing prostate cancer [HR (95% CI) = 1.68 (1.18–2.40)]. Conclusions: MetS increased the risk of developing urologic, kidney, and prostate cancers but had no association with the development of bladder cancer. [ABSTRACT FROM AUTHOR]

Recently, the strength, assistance with walking, rise from a chair, climb stairs, and falls (SARC-F) questionnaire has been developed to screen patients with signs of sarcopenia. However, its clinical benefit remains uncertain in elderly patients undergoing elective major surgeries. This study aimed to explore the role of the SARC-F questionnaire as a screening tool for patients who plan to undergo elective major surgery for urologic cancer and to also evaluate correlations of SARC-F scores with established indicators of sarcopenia. This retrospective observational study enrolled 815 patients over 40 years of age undergoing elective major surgery for urologic cancer and who were screened with the SARC-F questionnaire, preoperatively. The primary endpoint was an association between SARC-F scores and postoperative ambulation failure. Here we define postoperative ambulation failure as a condition where a patient is unable to walk independently within 2 days after surgery and required physical rehabilitation or was transferred to other hospitals in a bedridden state. The secondary endpoint was an association between SARC-F scores and overall survival (OS). Psoas muscle density (PMD) and psoas muscle index (PMI) were calculated from abdominal computed tomography images, and their correlations with SARC-F scores grouped by sex. Of the 815 patients, 738 (91%) were male and the median age was 72 years. Although SARC-F scores weakly correlated with PMD in males and moderately correlated in females (ρ = −0.222 and ρ = −0.474, respectively), their correlation with PMI was negligible (ρ = −0.179 and ρ = −0.084, respectively). SARC-F scores successfully discriminate postoperative ambulation failure in both males and females with the respective area under the receiver operating characteristic curve of 0.856 and 0.813. Multivariate analysis also showed that SARC-F scores greater than 4 are an independent risk factor of postoperative ambulation failure along with older age, lower PMD, and poor performance status. SARC-F scores greater than 4 were significantly associated with a shorter OS in the whole cohort (P < 0.001) and a subgroup of patients undergoing radical cystectomy (P = 0.03; median follow-up of 515 days). The SARC-F questionnaire might be applicable to identify elderly patients at a higher risk of unfavourable outcomes after major urologic cancer surgery. A randomised controlled trial is necessary to confirm this finding. [ABSTRACT FROM AUTHOR]

Objective: To assess long-term outcomes with robotic versus laparoscopic/thoracoscopic and open surgery for colorectal, urologic, endometrial, cervical, and thoracic cancers. Background: Minimally invasive surgery provides perioperative benefits and similar oncological outcomes compared with open surgery. Recent robotic surgery data have questioned long-term benefits. Methods: A systematic review and meta-analysis of cancer outcomes based on surgical approach was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using Pubmed, Scopus, and Embase. Hazard ratios for recurrence, disease-free survival (DFS), and overall survival (OS) were extracted/estimated using a hierarchical decision tree and pooled in RevMan 5.4 using inverse-variance fixed-effect (heterogeneity nonsignificant) or random effect models. Results: Of 31,204 references, 199 were included (7 randomized, 23 database, 15 prospective, 154 retrospective studies)—157,876 robotic, 68,007 laparoscopic/thoracoscopic, and 234,649 open cases. Cervical cancer: OS and DFS were similar between robotic and laparoscopic [1.01 (0.56, 1.80), P =0.98] or open [1.18 (0.99, 1.41), P =0.06] surgery; 2 papers reported less recurrence with open surgery [2.30 (1.32, 4.01), P =0.003]. Endometrial cancer: the only significant result favored robotic over open surgery [OS; 0.77 (0.71, 0.83), P <0.001]. Lobectomy: DFS favored robotic over thoracoscopic surgery [0.74 (0.59, 0.93), P =0.009]; OS favored robotic over open surgery [0.93 (0.87, 1.00), P =0.04]. Prostatectomy: recurrence was less with robotic versus laparoscopic surgery [0.77 (0.68, 0.87), P <0.0001]; OS favored robotic over open surgery [0.78 (0.72, 0.85), P <0.0001]. Low-anterior resection: OS significantly favored robotic over laparoscopic [0.76 (0.63, 0.91), P =0.004] and open surgery [0.83 (0.74, 0.93), P =0.001]. Conclusions: Long-term outcomes were similar for robotic versus laparoscopic/thoracoscopic and open surgery, with no safety signal or indication requiring further research (PROSPERO Reg#CRD42021240519).

Urologic cancers such as kidney, bladder, prostate, and uroepithelial cancers have recently become a considerable global health burden, and the response to immunotherapy is limited due to immune escape and immune resistance. Therefore, it is crucial to find appropriate and effective combination therapies to improve the sensitivity of patients to immunotherapy. DNA damage repair inhibitors can enhance the immunogenicity of tumor cells by increasing tumor mutational burden and neoantigen expression, activating immune-related signaling pathways, regulating PD-L1 expression, and reversing the immunosuppressive tumor microenvironment to activate the immune system and enhance the efficacy of immunotherapy. Based on promising experimental results from preclinical studies, many clinical trials combining DNA damage repair inhibitors (e.g., PARP inhibitors and ATR inhibitors) with immune checkpoint inhibitors (e.g., PD-1/PD-L1 inhibitors) are underway in patients with urologic cancers. Results from several clinical trials have shown that the combination of DNA damage repair inhibitors with immune checkpoint inhibitors can improve objective rates, progression-free survival, and overall survival (OS) in patients with urologic tumors, especially in patients with defective DNA damage repair genes or a high mutational load. In this review, we present the results of preclinical and clinical trials of different DNA damage repair inhibitors in combination with immune checkpoint inhibitors in urologic cancers and summarize the potential mechanism of action of the combination therapy. Finally, we also discuss the challenges of dose toxicity, biomarker selection, drug tolerance, drug interactions in the treatment of urologic tumors with this combination therapy and look into the future direction of this combination therapy.

Penile melanoma in situ is a very rare malignant neoplasm. Surgical treatment is the standard approach, although there are no recommendations regarding the extent and best technique.A 28-year-old male presented with a dark-brown macule on the glans, whose biopsy revealed melanoma in situ. A local excision followed by a partial resurfacing was performed, with follow-up revealing no sign of recurrence and good quality of life.Melanoma is a very dangerous tumor due to its metastization potential. The main challenge is early diagnosis. Surgical treatment is the best approach, although it is difficult to balance resection and organ preservation.

Urologic cancers, particularly kidney, bladder, and prostate cancer, have a growing incidence and account for about a million annual deaths worldwide. Treatments, including surgery, chemotherapy, radiotherapy, hormone therapy, and immunotherapy are the main therapeutic options in urologic cancers. Immunotherapy is now a clinical reality with marked success in solid tumors. Immunological checkpoint blockade, non-specific activation of the immune system, adoptive cell therapy, and tumor vaccine are the main modalities of immunotherapy. Immunotherapy has long been used to treat urologic cancers; however, dose-limiting toxicities and low response rates remain major challenges in the clinic. Herein, nanomaterial-based platforms are utilized as the "savior". The combination of nanotechnology with immunotherapy can achieve precision medicine, enhance efficacy, and reduce toxicities. In this review, we highlight the principles of cancer immunotherapy in urology. Meanwhile, we summarize the nano-immune technology and platforms currently used for urologic cancer treatment. The ultimate goal is to help in the rational design of strategies for nanomedicine-based immunotherapy in urologic cancer. [ABSTRACT FROM AUTHOR]

Long non-coding RNAs (lncRNAs) significantly influence gene regulation across epigenetic, transcriptional, and post-transcriptional levels through their interactions with DNA, RNA, and proteins. There is growing evidence of lncRNAs' critical roles in the emergence and progression of various diseases, including urological tumors (UTs), such as cancers of the kidney, bladder, and prostate. Research increasingly links lncRNA dysregulation to diverse cellular processes like invasion, metastasis, apoptosis, and chromatin remodeling. Among these, HOTAIR stands out for its pivotal role in oncogenesis, impacting treatment resistance, cell migration, proliferation, survival, and genomic integrity. This review provides an overview of HOTAIR's functions, its identification, and its biological significance. Furthermore, it delves into HOTAIR's involvement in UTs, underlining its potential as a therapeutic target and biomarker for innovative approaches to treating these cancers. [ABSTRACT FROM AUTHOR]

Abstract Objectives To describe the influence of the socioeconomic development on worldwide age-standardized incidence and mortality rates, as well as mortality-to-incidence ratio (MIR) and 5-year net survival of urologic cancer patients in recent years. Methods The Human Development Index (HDI) values were obtained from the United Nations Development Programme, data on age-standardized incidence/mortality rates of prostate, bladder and kidney cancer were retrieved from the GLOBOCAN database, 5-year net survival was provided by the CONCORD-3 program. We then evaluated the association between incidence/MIR/survival and HDI, with a focus on geographic variability as well as temporal patterns during the last 6 years. Results Urologic cancer incidence rates were positively correlated with HDIs, and MIRs were negatively correlated with HDIs. Prostate cancer survival also correlated positively with HDIs, solidly confirming the interrelation among cancer indicators and socioeconomic factors. Most countries experienced incidence decline over the most recent 6 years, and a substantial reduction in MIR was observed. Survival rates of prostate cancer have simultaneously improved. Conclusion Development has a prominent influence on urologic cancer outcomes. HDI values are significantly correlated with cancer incidence, MIR and survival rates. HDI values have risen along with increased incidence and improved outcomes of urologic caner in recent years.

Antibody‐drug conjugates represent a promising new treatment option that uses the targeting ability of an antibody to deliver cytotoxic drugs directly to tumors. Antibody‐drug conjugates provide the opportunity to deliver drugs to antigen‐expressing cancer cells while minimizing toxicity to normal tissue, achieving wider therapeutic windows. To date, three antibody‐drug conjugates have been approved by the US Food and Drug Administration, and many antibody‐drug conjugates are under clinical development for urological malignancies. In this paper, we review the mechanism, history, and development of antibody‐drug conjugates, and review the current landscape of antibody‐drug conjugates in urological malignancies including 12 targets and 18 antibody‐drug conjugates in prostate cancer, renal cancer, and urothelial cancer. Furthermore, we review the rational combination of antibody‐drug conjugates with immune checkpoint inhibitors and consider future prospects to enhance the therapeutic activity of antibody‐drug conjugates in urological malignancies.

Percivall Pott was an eighteenth-century English surgeon best known for three eponymous diseases: Pott's fracture, Pott's puffy tumour and Pott's disease of the spine. He wrote extensively, with treatises covering a wide range of surgical subjects, including cataracts, cranial trauma, hernias and neurology. Pott's practice came at a time when surgery was being transformed from the work of barbers into a scientific study. His publications had a wide-reaching impact, influencing contemporary practice and setting out building blocks for the work of those who came after him. This article aims to explore the life and career of Percivall Pott, looking in particular at his influence on the subjects of orthopaedics and occupational medicine., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Objectives: We aimed to evaluate the association between scores on each item of the SARC-F questionnaire and life expectancy in patients undergoing major surgery for urologic cancer., Methods: This retrospective study included 1018 patients undergoing elective major urologic cancer surgery. All patients completed the SARC-F questionnaire preoperatively. Demographic and clinical data were collected. The primary endpoint was an association between SARC-F scores and overall survival (OS)., Results: Of the 1018 patients, the median age was 72 years and 920 (90%) were male. Multivariate analysis revealed four factors significantly and independently associated with shorter OS: assistance with walking score ≥1 (Hazard ratio: HR=2.18, P =0.044), cancer stages ≥ III (HR=7.98, P <0.001), high blood loss ≥78 ml or blood transfusion during surgery (HR=4.53, P =0.007 and HR=2.41, P =0.037, respectively)., Conclusions: This study found that among the items of the SARC-F questionnaire, assistance with walking was a strong predictor of life expectancy. Incorporating such a simple screening tool into the preoperative assessment would help to ensure more appropriate perioperative care for urologic cancer patients., (Copyright: © 2024 Hylonome Publications.)

Background: Considering the relatively high 5-yr survival rate (76.9%) for bladder cancer (BC), its overall prevalence will probably continue to increase. Therefore, it is important to understand the effects of BC diagnosis and management, including psychological sequelae. Objective: To determine the prevalence of depression among elderly patients with BC and identify patient characteristics associated with depression. Design, setting, and participants: Survey responses from a population-based sample of 5787 patients older than 65 yr with a history of BC were retrieved from the Surveillance, Epidemiology and End Results-Medicare Health Outcomes Survey registry, spanning 1999–2014. Outcome measurements and statistical analysis: The primary outcome measured is the prevalence of a positive depression screen. Cancer characteristics and demographic, socioeconomic, health-related, and activities of daily living (ADL)-related data were reviewed. Univariate analysis was conducted to identify correlation between a positive depression screen and patient characteristics. Multivariate analysis was performed to identify independent predictors of depression. Results and limitations: The prevalence of a positive depression screen was 14.0%. Poor general health (p

Objective: Provide an overview of sexual dysfunction in female urologic cancer patients, approaches for assessing sexual problems, and interventions to treat sexual dysfunction in this patient population.Methods: A review of the literature in urologic oncology was conducted. Research on other female pelvic cancers with similar treatments was also reviewed.Results: Sexual health is an important element of women's quality of life that is often not discussed and problems remain unaddressed. Urologic cancer treatments commonly result in sexual dysfunction (e.g., dyspareunia, vaginal dryness, problems with orgasm) in female patients, although more research is necessary to understand the impact of non-surgical treatments (e.g., radiation, chemotherapy, immunotherapy). As such, provider teams should complete necessary screening for sexual dysfunction during and after treatment. The 5 A's model (i.e., Ask, Advise, Assess, Assist, Arrange Follow-Up) provides a helpful guide for communicating about and addressing sexual health concerns with patients during the screening process. If it is determined that referral for further assessment and treatment of sexual dysfunction is needed, a number of non-pharmacologic (e.g., pelvic floor physical therapy; psychosexual counseling) and pharmacologic treatment approaches are available.Conclusion: Sexual dysfunction is common in female urologic cancer survivors. Routine assessment and appropriate referral are essential for high quality patient care. [ABSTRACT FROM AUTHOR]

Sexual health concerns are prevalent and distressing in oncology patients and survivors. While urologic cancers are more prevalent in men, women often have more advanced disease at initial diagnosis, require more advanced surgical resection, and experience higher postoperative complication rates, as well as morbidity and mortality. Women with urologic cancers undergo treatment that is highly likely to impact their sexual function and well-being, however, attention to sexual recovery in this patient population has been limited. Barriers to sexual recovery in women with urologic cancers are biopsychosocial in nature and include complications related to treatment procedures, cancer-related distress, sexual anxiety and avoidance, partner and relational dynamics, and sexual communication skills. Healthcare providers do not adequately address sexual difficulties for these patients and their partners. Sexual minority women and transgender patients with urologic cancer have unique psychosocial and sexual health needs though, due to a lack of research, these remain poorly understood. More research is needed to pinpoint the sexual health needs of this specific oncology population and to explore how various treatment options, such as pelvic organ-sparing cystectomy, can impact sexual health outcomes. Evidence-based and multidisciplinary oncologic and survivorship care, which includes licensed mental health providers, certified sex therapists, and other sexual health experts, is essential for assisting women in their sexual recovery following urologic cancer.

Simple Summary: Bladder cancer is evidently a challenge as far as its prognosis and treatment are concerned. The investigation of potential biomarkers and therapeutic targets is indispensable and still in progress. Most studies attempt to identify differential signatures between distinct molecular tumor subtypes. Therefore, keeping in mind the heterogeneity of urinary bladder tumors, we attempted to identify a consensus gene-related signature between the common expression profile of bladder cancer and control samples. In the quest for substantive features, we were able to identify key hub genes, whose signatures could hold diagnostic, prognostic, or therapeutic significance, but, primarily, could contribute to a better understanding of urinary bladder cancer biology. Bladder cancer (BCa) is one of the most prevalent cancers worldwide and accounts for high morbidity and mortality. This study intended to elucidate potential key biomarkers related to the occurrence, development, and prognosis of BCa through an integrated bioinformatics analysis. In this context, a systematic meta-analysis, integrating 18 microarray gene expression datasets from the GEO repository into a merged meta-dataset, identified 815 robust differentially expressed genes (DEGs). The key hub genes resulted from DEG-based protein–protein interaction and weighted gene co-expression network analyses were screened for their differential expression in urine and blood plasma samples of BCa patients. Subsequently, they were tested for their prognostic value, and a three-gene signature model, including COL3A1, FOXM1, and PLK4, was built. In addition, they were tested for their predictive value regarding muscle-invasive BCa patients' response to neoadjuvant chemotherapy. A six-gene signature model, including ANXA5, CD44, NCAM1, SPP1, CDCA8, and KIF14, was developed. In conclusion, this study identified nine key biomarker genes, namely ANXA5, CDT1, COL3A1, SPP1, VEGFA, CDCA8, HJURP, TOP2A, and COL6A1, which were differentially expressed in urine or blood of BCa patients, held a prognostic or predictive value, and were immunohistochemically validated. These biomarkers may be of significance as prognostic and therapeutic targets for BCa. [ABSTRACT FROM AUTHOR]

Background: Hematospermia is an alarming symptom and can cause significant patient distress, but work‐up is often negative. Objective: To characterize the clinical evaluation of hematospermia and its association with the diagnosis of urologic malignancy. Materials and methods: Using MarketScan insurance claims database, we identified adult males 18–64 years old diagnosed with hematospermia from 2010 to 2018. Benign hematospermia was defined as the absence of hematuria and elevated prostate‐specific antigen. Patients with urologic cancer prior to diagnosis of hematospermia were excluded. We identified those who were diagnosed with a urologic malignancy. Results: The annual average incidence rate of hematospermia was 56.6 per 100,000 (95% confidence interval 55.4–57.8 per 100,000) in 2010 and increased to 73.6 per 100,000 (95% confidence interval 71.7–75.4 per 100,000) in 2018. A total of 56,157 patients presented with benign hematospermia. Most (57.5%) underwent at least one test, with the most common being urinalysis (51.7%), followed by prostate‐specific antigen testing (11.9%). All other tests were performed in less than 3% of patients. Forty‐seven patients were diagnosed with a urologic cancer, including 28 with prostate cancer (0.05%), nine with testicular cancer (0.016%), six with prostate carcinoma in situ (0.01%), and four with bladder cancer (0.007%). Stratified by age, there was only one cancer diagnosis (testicular) in 15,106 patients under 40 years (0.01%) and 46 cancer diagnoses in 40,611 patients 40 years old or above (0.11%). The median age of patients diagnosed with cancer was 56 years (interquartile range 52–61). Discussion and conclusion: A small minority of patients with benign hematospermia were later diagnosed with urologic cancer in a large nationally representative sample. After excluding hematuria with urinalysis, physicians should conservatively manage and reassure patients with hematospermia, especially those under 40 years of age. [ABSTRACT FROM AUTHOR]

• The primary contributor to caregiving burden is poor care recipient performance status. • Low caregivers confidence in providing care and own poor health lead to higher caregiving burden. • Socioeconomic disadvantage serves as a potential marker for increased caregiver burden. This study aimed to investigate the level of family caregivers' (FC) burden and the extent to which patient- and caregiver-related factors influence the caregiving burden among FCs of urologic cancer (UC) patients. A cross-sectional survey was conducted on caregivers of UC patients who sought cancer care. The modified caregiver strain index (MCSI) was used to assess FC burden. Just over half (54.3%) of FCs had moderate/high MCSI scores (score 9–26). By demographics, FCs who were unemployed (OR = 5.55, 95%CI 1.50–20.60) and perceived their current health condition as moderate/poor (OR = 6.05, 95%CI 1.95–18.78) reported higher odds of increased FC burden. Patient performance status played a pivotal role in exacerbating FC burden, whereby the odds of higher FC burden was 13 times higher in caregivers of UC patients having an Eastern Cooperative Oncology Group (ECOG) performance rating score of 3–4 (OR = 13.06, 95%CI 1.44–111.26) than those with a score of 0. Perceived lower levels of confidence in care provision were significantly associated with a higher level of strain (OR = 6.76, 985%CI 1.02–44.90). Care recipient performance status was a strong patient-related factor associated with higher FC burden regardless of duration of caregiving and other caregiver-related factors after adjusting for caregiver demographics.

Sarcopenia is a condition of low muscle strength and quantity, severe if low physical performances. The sarcopenia index (SI), calculated by blood levels of creatinine and cystatin C, had been reported to be correlated with skeletal muscle mass and is a potential simple screening tool for sarcopenia. We hypothesized that patients with a low SI, meaning low muscle mass, would have an inflated estimated glomerular filtration rate (eGFR) value based on serum creatinine levels. We also tested the prognostic value of the SI in a cohort of patients who had surgery for renal malignancies. We conducted a retrospective, observational study of 322 patients that had surgery for renal tumors in National Cancer Center Hospital East (Kashiwa, Chiba) between April 2017 and June 2023. We assessed sarcopenia measuring psoas muscle index (PMI), psoas muscle density (PMD), and skeletal muscle area (SMA) by computed tomography. We assessed the association between SI and eGFR before and after surgery. We also assessed the association between SI and postoperative outcome, including overall survival. Of the 322 patients, 211 (66%) were males, with a median age of 69 years. SI had a weak correlation with both PMI and PMD in males (PMI: ρ = 0.25; PMD: ρ = 0.21). In females, SI and PMD exhibited a low correlation (ρ = 0.26), while SI and PMI displayed an insignificant correlation (ρ = 0.19). The correlation between SMA and SI was moderate for both males and females (males: ρ = 0.51; females: ρ = 0.46). After radical nephrectomy, eGFR decreased in 98% of patients with high SI, compared to 69% of patients with low SI. We also demonstrated that low SI predicted poor prognosis. Clinicians can recognize the possibility of overestimated eGFR in the low SI group by measuring SI around the surgery. Low SI may also help predict poor prognosis. We assessed the value of sarcopenia Index (SI) in 322 patients who underwent surgery for renal tumors. We found that low SI was associated with poor prognosis and could cause the overestimation of estimated glomerular filtration rate based on serum creatinine. Calculating SI by measuring blood cystatin C might be useful for patients who require surgery for renal tumors. [ABSTRACT FROM AUTHOR]

Three-dimensional (3D) printing, as an evolving technology, enables the creation of patient-specific physical models with high precision; thus, it is widely used in various clinical practices, especially urologic cancer. There is an increasing need to clarify the contribution of 3D printing in the practice of urological cancer in order to identify various applications and improve understanding its benefits and challenges in clinical practice. Researches have focused on the use of 3D-printed models in patient and trainee education, surgical simulation, as well as surgical planning and guidance. This mini review will present the most recently published studies on the topic, including the applications of 3D-printed models, feasibility of performed procedures, possible simulated organs, application outcomes, and challenges involved in urologic cancer, to provide potential directions for future research.

Objectives: To describe the influence of the socioeconomic development on worldwide age-standardized incidence and mortality rates, as well as mortality-to-incidence ratio (MIR) and 5-year net survival of urologic cancer patients in recent years.Methods: The Human Development Index (HDI) values were obtained from the United Nations Development Programme, data on age-standardized incidence/mortality rates of prostate, bladder and kidney cancer were retrieved from the GLOBOCAN database, 5-year net survival was provided by the CONCORD-3 program. We then evaluated the association between incidence/MIR/survival and HDI, with a focus on geographic variability as well as temporal patterns during the last 6 years.Results: Urologic cancer incidence rates were positively correlated with HDIs, and MIRs were negatively correlated with HDIs. Prostate cancer survival also correlated positively with HDIs, solidly confirming the interrelation among cancer indicators and socioeconomic factors. Most countries experienced incidence decline over the most recent 6 years, and a substantial reduction in MIR was observed. Survival rates of prostate cancer have simultaneously improved.Conclusion: Development has a prominent influence on urologic cancer outcomes. HDI values are significantly correlated with cancer incidence, MIR and survival rates. HDI values have risen along with increased incidence and improved outcomes of urologic caner in recent years.

Abstract Background Several studies have reported that the systemic immune-inflammation index (SII) is associated with the prognosis of patients with urologic cancers (UCs). The aim of this study was to systematically evaluate the prognostic value of SII in UC patients. Methods We searched public databases for relevant published studies on the prognostic value of SII in UC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted and pooled to assess the relationships between SII and overall survival (OS), progression-free survival (PFS), cancer-specific survival (CSS), overall response rate (ORR) and disease control rate (DCR). Results A total of 14 studies with 3074 patients were included. From the pooled results, we found that high SII was associated with worse overall survival (OS) in patients with UC (HR 2.58, 95% CI 1.59–4.21). Patients with high SII values also had poorer PFS (HR 1.92, 95% CI 1.29–2.88) and CSS (HR 2.58, 95% CI 1.36–4.91) as well as lower ORRs (HR 0.40, 95% CI 0.22–0.71) than patients with low SII values. In addition, the subgroup analysis of OS and PFS showed that the prognosis of patients with high SII was worse than that of patients with low SII. Conclusions SII might be a promising noninvasive predictor in patients with UC. However, more samples and multicenter studies are needed to confirm the effectiveness of SII in predicting the prognosis of patients with UC.

Urologic cancers, particularly kidney, bladder, and prostate cancer, have a growing incidence and account for about a million annual deaths worldwide. Treatments, including surgery, chemotherapy, radiotherapy, hormone therapy, and immunotherapy are the main therapeutic options in urologic cancers. Immunotherapy is now a clinical reality with marked success in solid tumors. Immunological checkpoint blockade, non-specific activation of the immune system, adoptive cell therapy, and tumor vaccine are the main modalities of immunotherapy. Immunotherapy has long been used to treat urologic cancers; however, dose-limiting toxicities and low response rates remain major challenges in the clinic. Herein, nanomaterial-based platforms are utilized as the “savior”. The combination of nanotechnology with immunotherapy can achieve precision medicine, enhance efficacy, and reduce toxicities. In this review, we highlight the principles of cancer immunotherapy in urology. Meanwhile, we summarize the nano-immune technology and platforms currently used for urologic cancer treatment. The ultimate goal is to help in the rational design of strategies for nanomedicine-based immunotherapy in urologic cancer.

Background: Relaxed licensing restrictions on telehealth use during the COVID-19 pandemic allowed broad use irrespective of visit type. As these telehealth waivers expire, optimal uses of telehealth must be assessed to inform policy and clinical care. We evaluated patient experience associated with telehealth and in-person new or established visits., Methods: Patients seen in-person and via telehealth for urologic cancer care from August 2019 to June 2022 received a survey on satisfaction with care, perceptions of communication during their visit, travel time, travel costs, and days of work missed. We assessed survey responses with descriptive statistics., Results: Surveys were completed for 1,031 patient visits (N = 494 new visits, N = 537 established visits). Satisfaction rates were high for all visit modalities among new and established patients (mean score range 59.9-60.7 [maximum 63], P > 0.05). Patient-rated quality of the encounter did not differ by visit type and modality (P > 0.05, for nearly all comparisons). New in-person patient visits were associated with significantly higher travel costs (mean $496.10, SD $1021) compared with new telehealth visits (mean $26.60, SD $141; P < 0.001); 27% of new in-person patients required plane travel and 41% required a hotel stay (P < 0.001 vs. 0.8% and 3.2% of new telehealth patients, respectively)., Conclusions: Satisfaction outcomes among patients with urologic cancer receiving new patient telehealth care equaled those of new patients cared for in-person while costs were significantly lower. Offering telehealth exemption beyond COVID-19 licensing waivers to include new patient visits would allow for ongoing delivery of high-quality urologic cancer care irrespective of geographic location., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: Growing attention has been drawn to urologic tumors due to their rising incidence and suboptimal clinical treatment outcomes. Cancer therapy resistance poses a significant challenge in clinical oncology, limiting the efficacy of conventional treatments and contributing to disease progression. Recent research has unveiled a complex interplay between the host microbiota and cancer cells, highlighting the role of the microbiota in modulating therapeutic responses., Areas Covered: We used the PubMed and Web of Science search engines to identify key publications in the fields of tumor progression and urologic tumor treatment, specifically focusing on the role of the microbiota. In this review, we summarize the current literature on how microbiota influence the tumor microenvironment and anti-tumor immunity, as well as their impact on treatments for urinary system malignancies, highlighting promising future applications., Expert Opinion: We explore how the composition and function of the gut microbiota influence the tumor microenvironment and immune response, ultimately impacting treatment outcomes. Additionally, we discuss emerging strategies targeting the microbiota to enhance therapeutic efficacy and overcome resistance. The application of antibiotics, fecal microbiota transplantation, and oncolytic bacteria has improved tumor treatment outcomes, which provides a novel insight into developing therapeutic strategies for urologic cancer.

Urologic cancers (UCs), which include bladder, kidney, and prostate tumors, account for almost a quarter of all malignancies. Long non-coding RNAs (lncRNAs) are tissue-specific RNAs that influence cell growth, death, and division. LncRNAs are dysregulated in UCs, and their abnormal expression may allow them to be used in cancer detection, outlook, and therapy. With the identification of several novel lncRNAs and significant exploration of their functions in various illnesses, particularly cancer, the study of lncRNAs has evolved into a new obsession. MALAT1 is a flexible tumor regulator implicated in an array of biological activities and disorders, resulting in an important research issue. MALAT1 appears as a hotspot, having been linked to the dysregulation of cell communication, and is intimately linked to cancer genesis, advancement, and response to treatment. MALAT1 additionally operates as a competitive endogenous RNA, binding to microRNAs and resuming downstream mRNA transcription and operation. This regulatory system influences cell growth, apoptosis, motility, penetration, and cell cycle pausing. MALAT1's evaluation and prognosis significance are highlighted, with a thorough review of its manifestation levels in several UC situations and its association with clinicopathological markers. The investigation highlights MALAT1's adaptability as a possible treatment target, providing fresh ways for therapy in UCs as we integrate existing information The article not only gathers current knowledge on MALAT1's activities but also lays the groundwork for revolutionary advances in the treatment of UCs.

Purpose: Multidisciplinary team (MDT) conferences are currently the standard of care in cancer patients' management. Despite evidence supporting benefits to the majority of malignancies, a paucity of data exists examining the impact in urinary and male genital cancers. This study aims to evaluate the impact of MDT conferences in urologic cancer practice. Methods: Clinical plans discussed in urologic MDT conferences in Centro Hospitalar Universitário de Lisboa Central between January 2019 and December 2019 were retrospectively analysed. Clinical plans were categorized as accepted, changed, rejected (cases that had to be re-presented to the MDT because of insufficient staging or administrative issues) or no plan. MDT conferences' impact was assessed according to type of consultation, referral medical specialty and primary tumour type. Results: 710 clinical plans were discussed at the MDT conferences. 61.8% were accepted, 10.6% were changed, 16.5% were rejected and 11.1% of cases referred to MDT discussion had no defined clinical plan. First consultations had a higher rate of accepted clinical plans (63.4%) versus subsequent consultations (56.4%). Referrals by the urology specialty had the highest rate of acceptances (64.3%). On the stratification by primary tumour site, testicular cancer had the highest acceptance rate (70.3%), whereas bladder cancer had the lowest (47.8%). Conclusions: MDT conferences had an important impact in the management of 38.2% of cases. Therefore, all patients with urologic malignancies should be referred to MDT review to ensure optimal clinical care. [ABSTRACT FROM AUTHOR]

The number of cancer cases worldwide keeps growing unstoppably, despite the undeniable advances achieved by basic research and clinical practice. Urologic tumors, including some as prevalent as prostate, bladder or kidney tumors, are no exceptions to this rule. Moreover, the fact that many of these tumors are detected in early stages lengthens the duration of their treatment, with a significant increase in health care costs. In this scenario, prevention offers the most cost-effective long-term strategy for the global control of these diseases. Although specialized diets are not the only way to decrease the chances to develop cancer, epidemiological evidence support the role of certain plant-derived foods in the prevention of urologic cancer. In many cases, these plants are rich in antiangiogenic phytochemicals, which could be responsible for their protective or angiopreventive properties. Angiogenesis inhibition may contribute to slow down the progression of the tumor at very different stages and, for this reason, angiopreventive strategies could be implemented at different levels of chemoprevention, depending on the targeted population. In this review, epidemiological evidence supporting the role of certain plant-derived foods in urologic cancer prevention are presented, with particular emphasis on their content in bioactive phytochemicals that could be used in the angioprevention of cancer.

The aim of this study was to systematically explore the association between preoperative AGR and clinical outcomes in cancers of the urinary system.Methods: Relevant articles were searched in PubMed, Embase and Web of Science by two independent investigators from inception to June 1, 2018. Eligible studies were selected based on predetermined selection criteria. Summarized HRs or ORs and 95% CIs were calculated for prognosis and clinicopathologic features with the fixed-effects or random-effects models.Results: Eight cohort studies comprising 2,668 patients were included for analysis. The pooled results showed that a low AGR significantly correlated with poor OS (HR: 0.38, 95% CI: 0.27–0.48, P

Cyanobacteria or blue-green algae are becoming increasingly abundant in North American fresh water lakes. Toxins produced by cyanobacteria have been associated with gastrointestinal injury, liver failure, and nephrotoxicity. They have also been implicated in the pathogenesis of gastrointestinal and liver cancers. The purpose of the present study was to determine whether the incidence rates of gastrointestinal, liver, and urologic cancers are increasing in the province of Manitoba and, if so, whether these increases spatially and/or temporally correlate with areas where cyanobacterial contamination of fresh water lakes have been identified. Cancer incidence data were obtained from the Manitoba Cancer Registry. Cyanobacterial contamination data, as reflected by microcystin toxin concentrations, were available from the Manitoba Water Stewardship. ArcGIS mapping was employed to document spatial and temporal relationships between cancer incidence and cyanobacterial data. The results revealed that although the incidence rates for all three cancers have increased over the past 20–25 years, these increases were not disproportionally higher in zones with high microcystin toxin determinations. The results of this study argue against increased exposure to cyanotoxins as an explanation for the increase in gastrointestinal, liver and urologic cancers in Manitoba. [ABSTRACT FROM AUTHOR]

Objective: This study examined the prevalence of self‐perceived burden (SPB) and its association with health‐related quality of life (HRQoL) among urologic cancer patients. Methods: This was a prospective, cross‐sectional study. A total of 429 respondents diagnosed with urologic cancers (prostate, bladder and renal cancer) from Sarawak General Hospital and Subang Jaya Medical Centre in Malaysia were interviewed by using a structured questionnaire. SPB and HRQoL were measured by the Self‐perceived Burden Scale and the Functional Assessment of Cancer Therapy—General 7 Item Scale respectively. Results and Conclusion: Self‐perceived burden was experienced by 73.2% of the respondents. Respondents who had a lower education level, a monthly household income

Aim: Sarcopenia as a reliable prognostic predictor in urologic oncology surgery remains controversial, and no consensus amongst researchers exists regarding the management of patients with sarcopenia. This meta-analysis was conducted to investigate the association between sarcopenia and postoperative outcomes after urologic oncology surgery.Methods: A systematic search in MEDLINE (via PubMed), Embase, Web of Science and Cochrane Library databases was conducted to identify the potential studies published before August 2019. Odds ratios and hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated through inverse variance with random or fixed effects models.Results: Seventeen retrospective cohorts comprising 3,948 patients were included with sarcopenia prevalence between 25% and 68.9%. Patients with sarcopenia had significantly shorter overall survival (OS; HR = 2.06, 95% CI: 1.44-2.95; P < 0.001; I-square (I2) = 86%) and cancer-specific survival (HR = 2.16, 95% CI: 1.60-2.92; P < 0.001; I2 = 49.4%) than those without sarcopenia. Sarcopenia was independently associated with increased all-cause mortality (HR = 1.50, 95% CI: 1.26-1.80; P < 0.001; I2 = 0%) and cancer-specific mortality (HR = 1.50, 95% CI: 1.12-2.01; P = 0.006; I2 = 0%). No prognostic difference was observed in the postoperative risk of total complications and systemic progression except lymphovascular invasion status.Conclusions: Sarcopenia is an independent poor prognostic factor for patients undergoing urologic oncology surgery, particularly postoperative risks of short survival and increased mortality. Thus, preoperative sarcopenia evaluation can provide clinicians with important information to guide and individualise patient management and improve surgical outcomes. [ABSTRACT FROM AUTHOR]

Increased particulate matter (PM) exposure is positively associated with increased incidence and mortality of many human malignancies. However, evidence of urologic cancer is limited. We aimed to evaluate the association between PM 10 exposure and the relative risk of urologic cancer. This nationwide longitudinal cohort study included 231,997 participants who underwent a baseline health examination in 2008 from the National Health Information Database of Korea. The primary endpoint was newly diagnosed urologic cancer according to PM 10 exposure. Of the total 231,99 participants, 50,677 developed urologic cancer during a median follow-up of 6.7 years. After controlling for confounding factors, participants in the high PM 10 exposure group had a higher risk of kidney cancer (hazard ratio [HR] 1.111, 95% confidence interval [CI] 1.068-1.157) and prostate cancer (HR 1.083, 95% CI 1.058-1.109) than those in the low PM 10 exposure group. However, in urothelial cell carcinoma, there was no significant increase in the HRs in the high PM 10 exposure group. For kidney cancer, participants with the following characteristics were more susceptible: age < 65 years, female sex, decreased regular physical activity, current smoking, no diabetes, no hypertension, normal body mass index, and desirable total cholesterol level. For prostate cancer, participants with the following characteristics were more susceptible: decreased regular physical activity, current smoking, and no hypertension. High PM 10 exposure is associated with an increased risk of overall urologic cancers, especially kidney and prostate cancer., Competing Interests: Mi Jung Rho and Jihwan Park are married couples and are part of Dankook University, co-participating in the project.

Objective: Urologic cancers are not only among the most common types of cancers, but also among the most expensive cancers to treat in the United States. This study aimed to review the use of CEAs and other cost analyses in urologic oncology using large databases to better understand the value of management strategies of these cancers.Methods: A literature review on CEAs and other cost analyses in urologic oncology using large databases.Results: The options for and costs of diagnosing, treating, and following patients with urologic cancers can be expected to rise in the coming years. There are numerous opportunities in each urologic cancer to use CEAs to both lower costs and provide high-quality services. Improved cancer care must balance the integration of novelty with ensuring reasonable costs to patients and the health care system.Conclusion: With the increasing focus cost containment, appreciating the value of competing strategies in caring for our patients is pivotal. Leveraging methods such as CEAs and harnessing large databases may help evaluate the merit of established or emerging strategies. [ABSTRACT FROM AUTHOR]
