    泌尿生殖系统癌症(GUC)占所有人类癌症的五分之一以上。这使得开发其早期诊断方法成为现代生物医学的重要任务。循环microRNAs,短(17-25个核苷酸)的非编码RNA分子在人类生物体液中发现,并在细胞中发挥调节作用,被认为是有前途的癌症诊断和预后生物标志物,包括GUC。在这篇综述中,我们已经考虑了旨在评估microRNAs作为人类GUC类型的生物标志物作为膀胱恶性肿瘤的研究现状。肾,前列腺,睾丸,卵巢,还有子宫颈.特别注意致力于鉴定尿液中的microRNA作为替代“液体活检”的研究,这可能为大规模非侵入性筛查人类GUC提供最简单和最便宜的方法。使用microRNA面板代替单一类型的microRNA通常导致开发的诊断测试的更高的灵敏度和特异性。然而,到目前为止,作为人类GUC生物标志物的microRNAs评估工作仍具有研究性质,进一步将基于microRNA的诊断测试引入实践需要成功的临床试验。
    Genitourinary cancer (GUC) represents more than one fifth of all human cancers. This makes the development of approaches to its early diagnosis an important task of modern biomedicine. Circulating microRNAs, short (17-25 nucleotides) non-coding RNA molecules found in human biological fluids and performing a regulatory role in the cell, are considered as promising diagnostic and prognostic biomarkers of cancers, including GUC. In this review we have considered the current state of research aimed at assessing microRNAs as biomarkers of such human GUC types as malignant tumors of the bladder, kidney, prostate, testicles, ovaries, and cervix. A special attention has been paid to studies devoted to the identification of microRNAs in urine as a surrogate \"liquid biopsy\" that may provide the simplest and cheapest approach to mass non-invasive screening of human GUC. The use of microRNA panels instead of single types of microRNA generally leads to higher sensitivity and specificity of the developed diagnostic tests. However, to date, work on the microRNAs assessment as biomarkers of human GUC is still of a research nature, and the further introduction of diagnostic tests based on microRNAs into practice requires successful clinical trials.

    目标:在人工智能时代,几乎一半的患者使用互联网获取有关其疾病的信息。我们的研究旨在证明人工智能聊天机器人(AIC)提供的有关泌尿生殖器癌症治疗的信息的可靠性。
    方法:搜索频率最高的关于前列腺的关键词,膀胱,肾,和通过谷歌趋势进行的睾丸癌治疗被要求给3个不同的AIC(ChatGPT,双子座,Copilot)。答案由5位不同的考官在可读性方面进行了评估,可理解性,可操作性,可靠性,和透明度。
    结果:DISCERN评分评估表明ChatGPT和Gemini提供了中等质量的信息,而副驾驶的质量很低。(总评分;分别为41、42、35)。PEMAT-P可理解性得分较低(40%),PEMAT-P可操作性得分仅在双子座(60%)中等,而在其他双子座(40%)较低。根据Coleman-Liau指数,它们的可读性高于大学水平(分别为16.9、17.2、16)。
    结论:在人工智能时代,患者将不可避免地使用AIC,因为它们容易和快速的可访问性。然而,患者需要认识到AIC不提供特定阶段的治疗选择,但只有中等质量,关于疾病的低可靠性信息,以及很难阅读的信息。
    OBJECTIVE: In the era of artificial intelligence, almost half of the patients use the internet to get information about their diseases. Our study aims to demonstrate the reliability of the information provided by artificial intelligence chatbots (AICs) about urogenital cancer treatments.
    METHODS: The most frequently searched keyword about prostate, bladder, kidney, and testicular cancer treatment via Google Trends was asked to 3 different AICs (ChatGPT, Gemini, Copilot). The answers were evaluated by 5 different examiners in terms of readability, understandability, actionability, reliability, and transparency.
    RESULTS: The DISCERN score evaluation indicates that ChatGPT and Gemini provided moderate quality information, while Copilot\'s quality was low. (Total DISCERN scores; 41, 42, 35, respectively). PEMAT-P Understandability scores were low (40%) and PEMAT-P Actionability scores were moderate only for Gemini (60%) and low for the others (40%). Their readability according to the Coleman-Liau index was above the college level (16.9, 17.2, 16, respectively).
    CONCLUSIONS: In the era of artificial intelligence, patients will inevitably use AICs due to their easy and fast accessibility. However, patients need to recognize that AICs do not provide stage-specific treatment options, but only moderate-quality, low-reliability information about the disease, as well as information that is very difficult to read.

    在最近的十年里,循环肿瘤DNA(ctDNA)的分析通过允许快速检测可操作的分子靶标来改善癌症治疗。新一代的循环DNA测试现在正在商业化。这些测试的特点是0.01%vaF或更好的检测极限,允许检测放射学隐匿性分子残留病(MRD)。MRD测试有可能彻底改变新辅助和辅助治疗。此外,这些测试可用作肿瘤标志物来评估疾病反应。我们回顾了目前使用高灵敏度MRD测定的证据,特别关注泌尿生殖系统肿瘤。现在已经报道了在尿路上皮的多项研究,肾,最近还有睾丸癌.我们发现,在佐剂设置中,敏感性因肿瘤类型而异,在尿路上皮癌中可能达到100%的高水平。肿瘤知情MRD的特异性似乎在肿瘤类型中保留(98%-100%)。现在有几项试验正在前瞻性地验证生物标志物积分研究中的MRD测试,主要见于尿路上皮癌。
    In the recent decade, analysis of circulating tumor DNA (ctDNA) has improved cancer care by allowing for rapid detection of actionable molecular targets. A new generation of circulating DNA tests is now becoming available commercially. These tests are characterized by a superior limit of detection of 0.01% vaF or better, allowing for the detection of radiologically occult molecular residual disease (MRD). MRD tests have the potential to revolutionize neoadjuvant and adjuvant treatment. In addition, these tests can be used as tumor markers to assess disease response. We reviewed the current evidence for the use of high-sensitivity MRD assays with particular focus on the genitourinary tumors. Multiple studies have now been reported in urothelial, renal, and recently testicular carcinoma. We find that the sensitivity varies across tumor types in the adjuvant setting and may reach a high of 100% in urothelial cancer. Specificity in tumor-informed MRD appears to be preserved across tumor types (98%-100%). Several trials are now prospectively validating MRD testing in biomarker integral studies, mainly in urothelial carcinoma.

    结论:泌尿生殖系统癌症的年龄标准化率和趋势正在上升。因此,这项研究强调了通过筛查计划进行预防的重要性,提高认识,并利用适当的诊断方法。
    BACKGROUND: Cancers of the genitourinary system, particularly prostate, bladder, and kidney cancer, exhibit a high prevalence. Consequently, predicting the morbidity and mortality of genitourinary cancers holds great significance for future planning and implementation. This study aimed to examine the crude and age-standardized rates of mortality and the trend of genitourinary cancers over nine years in northern Iran.
    METHODS: This cross-sectional study used data on the number of deaths attributed to genitourinary cancers recorded in Babol City between 2013 and 2021 through the cause of death registration and classification system. Population estimates were derived from the latest census reports. Subsequently, crude and age-standardized rates, as well as trends for genitourinary cancers, were calculated.
    RESULTS: A total of 307 deaths occurred, with an average age of 75.6 ± 14.3 years due to genitourinary cancers. The crude and age-standardized rates of genitourinary cancers increased from 2.7 and 1.9 per hundred thousand people in 2013 to 7.7 and 5.9 per hundred thousand people in 2021, respectively. Over the study period, death rates significantly rose for men (P < 0.001) and remained constant for women (P = 0.444). Examination of genitourinary cancers revealed an upward trend for bladder (P = 0.012) and prostate (P = 0.012) cancers, while a stable trend was observed for kidney (P = 0.070) and testicular (P = 0.139) cancers.
    CONCLUSIONS: The age-standardized rate and trend of genitourinary cancers are rising. Consequently, this study emphasizes the importance of prevention through screening programs, raising awareness, and utilizing appropriate diagnostic methods.

    已在各种癌症类型中确定了与不同的治疗功效和临床预后相关的三级淋巴结构(TLSs)的存在。然而,TLS在泌尿生殖系统(GU)癌症中的机制作用和临床意义仍未完全探索。尽管在许多研究中描述了它们作为预测标志物的潜在作用,全面评估TLS的特点至关重要,包括编队的驱动因素,结构基础,细胞成分,成熟阶段,分子特征,和特定功能,以最大限度地发挥其对肿瘤特异性免疫的积极影响。这些结构对癌症进展和生物学的独特贡献激发了人们对这些结构作为抗肿瘤免疫介质的兴趣。新兴数据试图探索针对TLS的治疗干预措施的效果。因此,更好地了解TLS的分子和表型异质性,可能有助于开发靶向TLS的治疗策略,从而在免疫治疗环境中获得最佳的GU癌症临床获益.在这次审查中,我们关注癌症进展中TLS的表型和功能异质性,当前针对TLS的治疗干预以及TLS在GU癌症中的临床意义和治疗潜力。
    The presence of tertiary lymphoid structures (TLSs) associated with distinct treatment efficacy and clinical prognosis has been identified in various cancer types. However, the mechanistic roles and clinical implications of TLSs in genitourinary (GU) cancers remain incompletely explored. Despite their potential role as predictive markers described in numerous studies, it is essential to comprehensively evaluate the characteristics of TLSs, including drivers of formation, structural foundation, cellular compositions, maturation stages, molecular features, and specific functionality to maximize their positive impacts on tumor-specific immunity. The unique contributions of these structures to cancer progression and biology have fueled interest in these structures as mediators of antitumor immunity. Emerging data are trying to explore the effects of therapeutic interventions targeting TLSs. Therefore, a better understanding of the molecular and phenotypic heterogeneity of TLSs may facilitate the development of TLSs-targeting therapeutic strategies to obtain optimal clinical benefits for GU cancers in the setting of immunotherapy. In this review, the authors focus on the phenotypic and functional heterogeneity of TLSs in cancer progression, current therapeutic interventions targeting TLSs and the clinical implications and therapeutic potential of TLSs in GU cancers.

    泌尿生殖系统癌症相关死亡率的社会人口统计学差异尚未得到充分研究,特别是在多种癌症类型中。本研究旨在调查性别,种族,以及美国最常见的泌尿生殖系统癌症死亡率的地理差异。
    前列腺死亡率数据,膀胱,肾,和睾丸癌从疾病控制和预防中心(CDC)WONDER数据库在1999年至2020年之间获得。按年份分析了年龄调整后的死亡率(AAMR),性别,种族,城乡地位,和地理区域使用P<0.05的显著性水平。
    总的来说,用于前列腺的AAMR,膀胱,肾癌显著下降,而睾丸癌相关死亡率保持稳定.膀胱和肾癌AAMR男性比女性高3-4倍。前列腺癌死亡率在黑人/非裔美国人中最高,2015年后开始增加。白种人膀胱癌死亡率显著下降,黑人个体,非洲裔美国人,和亚洲人/太平洋岛民,但在美洲印第安人/阿拉斯加原住民中保持稳定。与肾癌相关的死亡率在白人中最高,但在其他种族中显着下降。白人的睾丸癌死亡率显着增加,但黑人和非裔美国人保持稳定。大城市地区的泌尿生殖系统癌症死亡率下降,但在非大城市地区增加(膀胱癌和睾丸癌)或保持稳定(肾癌)。前列腺癌和肾癌死亡率在中西部最高,南方的膀胱癌,西方的睾丸癌.
    在美国泌尿生殖系统癌症的死亡率趋势中存在显著的社会人口统计学差异。这些发现强调了有针对性的干预措施和进一步研究的必要性,以解决这些差异并改善所有受泌尿生殖系统癌症影响的人群的结果。
    UNASSIGNED: Sociodemographic disparities in genitourinary cancer-related mortality have been insufficiently studied, particularly across multiple cancer types. This study aimed to investigate gender, racial, and geographic disparities in mortality rates for the most common genitourinary cancers in the United States.
    UNASSIGNED: Mortality data for prostate, bladder, kidney, and testicular cancers were obtained from the Centers for Disease Control and Prevention (CDC) WONDER database between 1999 and 2020. Age-adjusted mortality rates (AAMRs) were analyzed by year, gender, race, urban-rural status, and geographic region using a significance level of p < 0.05.
    UNASSIGNED: Overall, AAMRs for prostate, bladder, and kidney cancer declined significantly, while testicular cancer-related mortality remained stable. Bladder and kidney cancer AAMRs were 3-4 times higher in males than females. Prostate cancer mortality was highest in black individuals/African Americans and began increasing after 2015. Bladder cancer mortality decreased significantly in White individuals, Black individuals, African Americans, and Asians/Pacific Islanders but remained stable in American Indian/Alaska Natives. Kidney cancer-related mortality was highest in White individuals but declined significantly in other races. Testicular cancer mortality increased significantly in White individuals but remained stable in Black individuals and African Americans. Genitourinary cancer mortality decreased in metropolitan areas but either increased (bladder and testicular cancer) or remained stable (kidney cancer) in non-metropolitan areas. Prostate and kidney cancer mortality was highest in the Midwest, bladder cancer in the South, and testicular cancer in the West.
    UNASSIGNED: Significant sociodemographic disparities exist in the mortality trends of genitourinary cancers in the United States. These findings highlight the need for targeted interventions and further research to address these disparities and improve outcomes for all populations affected by genitourinary cancers.

    目的:卡博替尼和纳武单抗(CaboNivo)单独或与伊匹单抗(CaboNivoIpi)一起在转移性尿路上皮癌(mUC)患者中显示出良好的疗效和安全性,转移性肾细胞癌(mRCC),和罕见的泌尿生殖系统(GU)肿瘤在剂量递增I期研究中。我们报告安全性的最终数据分析,总反应率(ORR),无进展生存期(PFS),I期患者和7个扩展队列的总生存期(OS)。
    方法:这是研究者发起的,多中心,第一阶段审判。CaboNivo双峰扩展队列包括(1)MUC,(2)mRCC,和(3)膀胱/脐尿管腺癌;CaboNivoIpi三联体扩增队列包括(1)mUC,(2)mRCC,(3)阴茎癌,和(4)膀胱鳞状细胞癌和其他罕见的GU肿瘤(ClinicalTrials.gov标识符:NCT02496208)。
    结果:该研究纳入了120例接受CaboNivo(n=64)或CaboNivoIpi(n=56)治疗的患者,中位随访时间为49.2个月。在108名可评估患者中(CaboNivon=59;CaboNivoIpin=49),ORR为38%(完全缓解率11%),中位缓解持续时间为20个月.MUC的ORR为42.4%,mRCC为62.5%(n=16),膀胱鳞状细胞癌占85.7%(n=7),44.4%为阴茎癌(n=9),肾髓样癌占50.0%(n=2)。84%的CaboNivo患者和80%的CaboNivoIpi患者发生≥3级治疗相关不良事件。
    结论:CaboNivo和CaboNivoIpi在患有多种GU恶性肿瘤的患者中具有临床活性和安全性,特别是透明细胞RCC,尿路上皮癌,和罕见的GU肿瘤,如膀胱鳞状细胞癌,膀胱小细胞癌,膀胱腺癌,肾髓样癌,还有阴茎癌.
    OBJECTIVE: Cabozantinib and nivolumab (CaboNivo) alone or with ipilimumab (CaboNivoIpi) have shown promising efficacy and safety in patients with metastatic urothelial carcinoma (mUC), metastatic renal cell carcinoma (mRCC), and rare genitourinary (GU) tumors in a dose-escalation phase I study. We report the final data analysis of the safety, overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) of the phase I patients and seven expansion cohorts.
    METHODS: This is an investigator-initiated, multicenter, phase I trial. CaboNivo doublet expansion cohorts included (1) mUC, (2) mRCC, and (3) adenocarcinoma of the bladder/urachal; CaboNivoIpi triplet expansion cohorts included (1) mUC, (2) mRCC, (3) penile cancer, and (4) squamous cell carcinoma of the bladder and other rare GU tumors (ClinicalTrials.gov identifier: NCT02496208).
    RESULTS: The study enrolled 120 patients treated with CaboNivo (n = 64) or CaboNivoIpi (n = 56), with a median follow-up of 49.2 months. In 108 evaluable patients (CaboNivo n = 59; CaboNivoIpi n = 49), the ORR was 38% (complete response rate 11%) and the median duration of response was 20 months. The ORR was 42.4% for mUC, 62.5% for mRCC (n = 16), 85.7% for squamous cell carcinoma of the bladder (n = 7), 44.4% for penile cancer (n = 9), and 50.0% for renal medullary carcinoma (n = 2). Grade ≥ 3 treatment-related adverse events occurred in 84% of CaboNivo patients and 80% of CaboNivoIpi patients.
    CONCLUSIONS: CaboNivo and CaboNivoIpi demonstrated clinical activity and safety in patients with multiple GU malignancies, especially clear cell RCC, urothelial carcinoma, and rare GU tumors such as squamous cell carcinoma of the bladder, small cell carcinoma of the bladder, adenocarcinoma of the bladder, renal medullary carcinoma, and penile cancer.

    背景:这项研究旨在评估是否将低肌肉质量与其他身体成分异常相结合,如肌肉骨化或肥胖,可以提高大型胃肠道和泌尿生殖系统恶性肿瘤队列的生存预测准确性。
    方法:总共,回顾性分析2015年经手术治疗的胃肠道或泌尿生殖系统癌患者。骨骼肌指数,骨骼肌放射密度,并测定内脏/皮下脂肪指数。主要结果是由医院记录确定的总生存期。多变量Cox风险模型用于确定生存率差的独立预测因子。评估C统计学以量化有或没有结合身体成分参数的模型的预后能力。
    结果:所有4项测量结果均对生存曲线进行了显著划分。骨骼肌放射密度与非癌症相关死亡相关,但与癌症特异性生存率无关。低骨骼肌指数患者的生存结局较差(5年OS;65.2%),特别是当存在与低骨骼肌放射密度(5年总生存率;50.2%)。所有检查的身体成分参数都是较低总生存率的独立预测因子。在不纳入身体成分参数的情况下预测总生存期的模型的c指数为0.68,但在纳入低骨骼肌指数时增加到0.71,在纳入低骨骼肌指数和低骨骼肌放射密度/内脏脂肪组织指数/皮下脂肪组织指数时增加到0.72。
    结论:患者表现出低骨骼肌指数和其他身体成分异常,特别是低骨骼肌放射密度,总体生存率较差。结合多种身体成分的模型对于肿瘤学环境中的死亡率预测很有价值。
    BACKGROUND: This study aimed to evaluate if combining low muscle mass with additional body composition abnormalities, such as myosteatosis or adiposity, could improve survival prediction accuracy in a large cohort of gastrointestinal and genitourinary malignancies.
    METHODS: In total, 2015 patients with surgically-treated gastrointestinal or genitourinary cancer were retrospectively analyzed. Skeletal muscle index, skeletal muscle radiodensity, and visceral/subcutaneous adipose tissue index were determined. The primary outcome was overall survival determined by hospital records. Multivariate Cox hazard models were used to identify independent predictors for poor survival. C-statistics were assessed to quantify the prognostic capability of the models with or without incorporating body composition parameters.
    RESULTS: Survival curves were significantly demarcated by all 4 measures. Skeletal muscle radiodensity was associated with non-cancer-related deaths but not with cancer-specific survival. The survival outcome of patients with low skeletal muscle index was poor (5-year OS; 65.2%), especially when present in combination with low skeletal muscle radiodensity (5-year overall survival; 50.2%). All examined body composition parameters were independent predictors of lower overall survival. The model for predicting overall survival without incorporating body composition parameters had a c-index of 0.68 but increased to 0.71 with the inclusion of low skeletal muscle index and 0.72 when incorporating both low skeletal muscle index and low skeletal muscle radiodensity/visceral adipose tissue index/subcutaneous adipose tissue index.
    CONCLUSIONS: Patients exhibiting both low skeletal muscle index and other body composition abnormalities, particularly low skeletal muscle radiodensity, had poorer overall survival. Models incorporating multiple body composition prove valuable for mortality prediction in oncology settings.
