    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.

    背景:泌尿生殖系统的癌症,尤其是前列腺,膀胱,和肾癌,表现出很高的患病率。因此,预测泌尿生殖系统癌症的发病率和死亡率对于未来的规划和实施具有重要意义。这项研究旨在检查伊朗北部九年来的粗略和年龄标准化死亡率以及泌尿生殖系统癌症的趋势。
    方法:这项横断面研究使用了2013年至2021年在巴博尔市通过死亡原因登记和分类系统记录的归因于泌尿生殖系统癌症的死亡人数数据。人口估计数来自最新的人口普查报告。随后,粗率和年龄标准化率,以及泌尿生殖系统癌症的趋势,被计算。
    结果:共发生307例死亡,由于泌尿生殖系统癌症,平均年龄为75.6±14.3岁。泌尿生殖系统癌症的粗比率和年龄标准化比率分别从2013年的每10万人2.7和1.9增加到2021年的每10万人7.7和5.9。在学习期间,男性死亡率显著上升(P<0.001),女性死亡率保持不变(P=0.444).泌尿生殖系统癌症检查显示膀胱癌(P=0.012)和前列腺癌(P=0.012)呈上升趋势,而肾癌(P=0.070)和睾丸癌(P=0.139)的趋势稳定。
    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:证明经皮不可逆电穿孔(IRE)治疗淋巴结转移的安全性和有效性。
    方法:经IRB批准的,对胃肠道淋巴结转移患者进行单中心回顾性分析,和泌尿生殖系统原发性癌症。通过评估Clavien-Dindo分类的并发症来评估主要客观安全性。疗效由随访影像学的肿瘤反应和局部无进展生存期(LPFS)决定.次要结局指标为技术成功(充分消融边缘>5mm的完全消融),住院时间和远处无进展生存期(DPFS)。
    结果:19例患者在2018年6月至2023年2月期间因淋巴结转移接受了经皮IRE,靠近关键结构,比如脉管系统,肠,或神经。在所有情况下都取得了技术成功。4例患者发生并发症(21.1%),包括两个自限性1级血肿,1级腹痛,和2级神经疼痛用药物治疗。17名病人过夜住院,一名病人住了两晚,另一名病人住了十四个晚上。中位随访时间为25.5个月。到局部进展的中位时间为24.1个月(95%CI:0-52.8),其中1-2-,5年LPFS为57.9%,57.9%和20.7%,分别。远端进展的中位时间为4.3个月(95%CI:0.3-8.3),其中1-2-,5年DPFS为31.6%,13.2%和13.2%,分别。
    结论:IRE是一种安全有效的微创治疗淋巴结转移的方法,其中温度依赖性消融可能是禁忌的。在神经附近使用IRE时应小心。
    OBJECTIVE: Demonstrating the safety and efficacy of percutaneous irreversible electroporation (IRE) for the treatment of lymph node metastases.
    METHODS: An IRB-approved, single-center retrospective review was performed on patients with lymph node metastases gastrointestinal, and genitourinary primary cancers. Primary objective safety was evaluated by assessing complications graded according to the Clavien-Dindo Classification, and efficacy was determined by tumor response on follow-up imaging and local progression-free survival (LPFS). Secondary outcome measures were technical success (complete ablation with an adequate ablative margin > 5 mm), length of hospital stay and distant progression-free survival (DPFS).
    RESULTS: Nineteen patients underwent percutaneous IRE between June 2018 and February 2023 for lymph node metastases, close to critical structures, such as vasculature, bowel, or nerves. The technical success was achieved in all cases. Complications occurred in four patients (21.1%), including two self-limiting grade 1 hematomas, a grade 1 abdominal pain, and grade 2 nerve pain treated with medication. Seventeen patients were hospitalized overnight, one patient stayed two nights and another patient stayed fourteen nights. Median follow-up was 25.5 months. Median time to local progression was 24.1 months (95% CI: 0-52.8) with 1-, 2-, and 5-year LPFS of 57.9%, 57.9% and 20.7%, respectively. Median time to distant progression was 4.3 months (95% CI: 0.3-8.3) with 1-, 2-, and 5-year DPFS of 31.6%, 13.2% and 13.2%, respectively.
    CONCLUSIONS: IRE is a safe and effective minimally-invasive treatment for lymph node metastases in locations, where temperature dependent ablation may be contraindicated. Care should be taken when employing IRE near nerves.

    随着世界范围内泌尿生殖系统肿瘤的高发,泌尿系统肿瘤是男性最常见的十大肿瘤之一,前列腺癌排名第一,膀胱癌排名第四。耐药的泌尿生殖道肿瘤患者往往预后不良。近年来,研究人员已经发现了许多特定的癌症抗原,这导致了几种新的抗癌药物的开发。使用蛋白质分析技术,研究人员开发了用于治疗晚期泌尿生殖道肿瘤的免疫检查点抑制剂(ICIs)和抗体偶联药物(ADC).然而,肿瘤耐药常导致单药治疗失败。因此,ICIs和ADC组合的临床试验已经在世界各地的许多中心进行.本文综述了ICIs的2期和3期临床研究,ADC,以及它们在泌尿生殖道肿瘤治疗中的组合,以突出为患者选择个性化治疗策略的安全有效方法。ICIs激活免疫系统,而ADC将单克隆抗体与毒素联系起来,当两种药物联合使用时可以达到协同作用。这种协同作用为泌尿生殖肿瘤的治疗提供了多种优势。
    With the high incidence of urogenital tumors worldwide, urinary system tumors are among the top 10 most common tumors in men, with prostate cancer ranking first and bladder cancer fourth. Patients with resistant urogenital tumors often have poor prognosis. In recent years, researchers have discovered numerous specific cancer antigens, which has led to the development of several new anti-cancer drugs. Using protein analysis techniques, researchers developed immune checkpoint inhibitors (ICIs) and antibody-conjugated drugs (ADCs) for the treatment of advanced urogenital tumors. However, tumor resistance often leads to the failure of monotherapy. Therefore, clinical trials of the combination of ICIs and ADCs have been carried out in numerous centers around the world. This article reviewed phase 2 and 3 clinical studies of ICIs, ADCs, and their combination in the treatment of urogenital tumors to highlight safe and effective methods for selecting individualized therapeutic strategies for patients. ICIs activate the immune system, whereas ADCs link monoclonal antibodies to toxins, which can achieve a synergistic effect when the two drugs are combined. This synergistic effect provides multiple advantages for the treatment of urogenital tumors.

    神经内分泌癌(NEC)是一种罕见但潜在的危害性肿瘤。这项研究的目的是开发NEC患者在泌尿生殖系统中生存的预后模型,并随后验证这些模型。共抽取7125例神经内分泌肿瘤(NEN)患者。不同类型NEN患者倾向评分匹配(PSM)前后生存率比较共有3057名NEC患者,他的信息是完整的,被提取。通过利用最小绝对收缩和选择算子回归模型(LASSO)和Fine&Gary模型(FGM)选择NEC影响因素。此外,建立了列线图。为了验证预测的准确性,使用Bootstrap自采样技术和接收器工作特性曲线验证了效率。利用LASSO和FGM构建了三个模型。通过对曲线下面积和决策曲线进行分析来实现验证的确认。此外,FGS(使用FGM的DSS分析)模型产生了更高的净效益。最大限度地发挥患者的优势,FGS模型忽略了额外事件的影响。通过利用这些模型,预期患者在治疗选择和生存评估方面具有优势。
    Neuroendocrine carcinoma (NEC) is a rare yet potentially perilous neoplasm. The objective of this study was to develop prognostic models for the survival of NEC patients in the genitourinary system and subsequently validate these models. A total of 7125 neuroendocrine neoplasm (NEN) patients were extracted. Comparison of survival in patients with different types of NEN before and after propensity score-matching (PSM). A total of 3057 patients with NEC, whose information was complete, were extracted. The NEC influencing factors were chosen through the utilization of the least absolute shrinkage and selection operator regression model (LASSO) and the Fine & Gary model (FGM). Furthermore, nomograms were built. To validate the accuracy of the prediction, the efficiency was verified using bootstrap self-sampling techniques and receiver operating characteristic curves. LASSO and FGM were utilized to construct three models. Confirmation of validation was achieved by conducting analyses of the area under the curve and decision curve. Moreover, the FGS (DSS analysis using FGM) model produced higher net benefits. To maximize the advantages for patients, the FGS model disregarded the influence of additional occurrences. Patients are expected to experience advantages in terms of treatment options and survival assessment through the utilization of these models.
