Background

Although a survival benefit was observed in patients with metastatic renal cell carcinoma (mRCC) who underwent cytoreductive nephrectomy (CN), there is a lack of effective tools for predicting which individuals are likely to benefit from surgical intervention. Herein, we developed a predictive model using data from the Surveillance, Epidemiology, and End Results (SEER) database.

Materials and Methods

Patients diagnosed with mRCC were screened from the SEER database (2010-2020), supplemented by patients from East Asia. Patients were categorized into surgical and non-surgical groups, with propensity score matching conducted to balance baseline characteristics. Logistic regression analysis was performed to identify independent factors associated with benefits and a nomogram was constructed based on these factors.

Results

This study included 11,044 cases from the SEER database and 50 cases from an external validation cohort. CN was identified as an independent protective factor for OS. A nomogram was established, and it performed well in the training and validation sets. The calibration curves and DCA confirmed that the nomogram model could precisely predict the probability of surgical benefit. We used the nomogram to classify surgical patients into benefit and non-benefit groups. Then, we found that OS was significantly higher in the benefit group than in the non-benefit group. The external validation cohort observed the same result (P=0.035).

Conclusion

While CN offers potential benefits for patients with mRCC, its applicability varies across the patient population. Our study constructed a nomogram that quantitatively assesses the likelihood of surgical benefit in mRCC patients, facilitating more tailored therapeutic decision-making.

这项研究旨在评估与转移性肾细胞癌(mRCC)细胞切除肾切除术(CN)相关的预后增强效应,并建立一个预测提名图,用于确定哪些患者最有可能从细胞切除肾切除术中获益。虽然在接受细胞切除肾切除术(CN)的转移性肾细胞癌(mRCC)患者中观察到了生存获益,但缺乏有效的工具来预测哪些人可能从手术干预中获益。在此,我们利用监测、流行病学和最终结果(SEER)数据库中的数据开发了一个预测模型。我们从 SEER 数据库(2010-2020 年)中筛选出被诊断为 mRCC 的患者,并补充了来自东亚的患者。患者被分为手术组和非手术组,并进行倾向评分匹配(PSM)以平衡基线特征。通过逻辑回归分析确定了与获益相关的独立因素,并根据这些因素构建了提名图。这项研究包括 SEER 数据库中的 11,044 例病例和外部验证队列中的 50 例病例。CN被确定为OS的独立保护因素(P<0.001)。建立的提名图在训练集和验证集中表现良好(AUC:0.786 和 0.761)。校准曲线和 DCA 证实,提名图模型可以精确预测手术获益的概率。我们使用提名图将手术患者分为获益组和非获益组。然后,我们发现获益组的 OS 明显高于非获益组。外部验证队列也观察到了同样的结果(P=0.035)。虽然 CN 可为 mRCC 患者带来潜在益处,但其适用性因患者群体而异。我们的研究构建了一个提名图,对mRCC患者手术获益的可能性进行定量评估,从而有助于做出更有针对性的治疗决策。我们的研究表明,CN 可改善 mRCC 的预后,但只有特定患者才能从 CN 中获益。目前还没有预测工具来确定哪些患者会受益。因此,我们的目标是利用 SEER 数据库中的数据开发一个提名图,以确定可从 CN 中获益的 mRCC 患者。

Introduction

Second-generation androgen receptor axis-targeting (ARAT) agents have become a standard treatment for patients with advanced prostate cancer (PC), however much remains unknown about the potential cardiovascular toxicities.

Patients and Methods

We performed a systematic search of PubMed, Embase, Web of Science, and Cochrane library for randomized controlled trials of patients receiving ARAT agents for PC from inception to March 2023. The odds ratios (ORs) of all-grade and high-grade cardiovascular adverse events (CVAEs) for patients treated with and without ARAT agents were pooled for meta-analysis. Subgroup analyses based on PC type and treatment regimen were conducted.

Results

A total of 15 double-blind placebo-controlled phase 3 trials comprising 15,842 patients were included. In addition to hot flush and hypertension of any degree of severity, inclusion of ARAT agents was associated with a significantly higher risk of acute myocardial infarction (OR: 1.96, 95% CI: 1.05-3.68, P = .04), myocardial infarction (OR: 2.44, 95% CI: 1.27-4.66, P = .007) and angina pectoris (OR: 2.00, 95% CI: 1.00-4.02, P = .05). With regard to individual ARAT agents, enzalutamide was associated with a significantly higher risk of acute myocardial infarction (OR: 3.11, 95% CI: 1.17-8.28, P = .02), coronary artery disease (OR: 8.33, 95% CI: 1.54-44.95, P = .01), and high-grade hypertension (OR: 4.94, 95% CI: 1.11-22.06, P = .04), while abiraterone and apalutamide were associated with a significantly higher risk of angina pectoris (OR: 5.48, 95% CI: 1.23-24.33, P = .03) and myocardial infarction (OR: 7.00, 95% CI: 1.60-30.62, P = .01), respectively.

Conclusion

The inclusion of ARAT agents was associated with a significantly higher risk of several CVAEs. Clinicians should remain vigilant, both in pre-treatment screening and monitoring for clinical symptoms and signs, when considering ARAT agent particularly for patients with pre-existing risk factors.

第二代雄激素受体轴靶向(ARAT)药物已成为晚期前列腺癌(PC)患者的标准治疗方法,但关于其潜在的心血管毒性仍有很多未知之处。我们在 PubMed、Embase、Web of Science 和 Cochrane 图书馆中系统检索了从开始到 2023 年 3 月接受 ARAT 药物治疗的 PC 患者的随机对照试验。将接受和未接受ARAT药物治疗的患者发生全级别和高级别心血管不良事件(CVAEs)的几率比(ORs)汇总后进行荟萃分析。根据 PC 类型和治疗方案进行了分组分析。共纳入了 15 项双盲安慰剂对照 3 期试验,包括 15,842 名患者。除任何严重程度的潮热和高血压外,纳入 ARAT 药物还与急性心肌梗死(OR:1.96,95% CI:1.05-3.68,p = 0.04)、心肌梗死(OR:2.44,95% CI:1.27-4.66,p = 0.007)和心绞痛(OR:2.00,95% CI:1.00-4.02,p = 0.05)风险显著升高有关。就单个 ARAT 药物而言,恩杂鲁胺与急性心肌梗死(OR:3.11,95% CI:1.17-8.28,p = 0.02)、冠状动脉疾病(OR:8.33,95% CI:1.54-44.95,p = 0.01)和高级别高血压(OR:4.94,95% CI:1.11-22.06,p = 0.04),而阿比特龙和阿帕鲁胺分别与心绞痛(OR:5.48,95% CI:1.23-24.33,p = 0.03)和心肌梗死(OR:7.00,95% CI:1.60-30.62,p = 0.01)风险显著升高相关。ARAT药物的加入与几种CVAE的风险显著升高有关。临床医生在考虑使用抗逆转录病毒药物时应保持警惕,既要进行治疗前筛查,也要监测临床症状和体征,尤其是对已有风险因素的患者。

Background and Objective

Considering the rapidly evolving treatment landscape of renal cell carcinoma (RCC), recent descriptions of the RCC population in the UK are lacking, as are real-world data on treatment and patient outcomes. To analyse the demographic and clinical characteristics, treatment patterns, and overall survival of patients with RCC using national data sets in England.

Patients and Methods

This was a retrospective cohort study of patients diagnosed with RCC (all stages) between 2014-2018 using demographic, clinical, cancer registration, and treatment data. Patients were followed until death or study end (December 31, 2020). Treatments administered in each line were described to understand treatment sequencing. Kaplan–Meier methods were used for time-to-event analyses. Factors associated with discontinuation and survival were identified using Cox proportional hazard models.

Results and Limitations

Among 32,577 included patients, the median age at diagnosis was 66 years, 63.4% were male, and 6,786 (20.8%) had metastatic RCC at diagnosis. Tyrosine kinase inhibitor (TKI) monotherapy was the most common treatment class across lines. Over three quarters of patients (78.5% [95% CI: 78.0-78.9]) were alive one year after diagnosis (93.2% in the non-metastatic at diagnosis subgroup and 37.1% among patients with metastases at diagnosis). At three years post initial diagnosis, 18.0% patients were alive in the metastatic at diagnosis subgroup. Rapid evolution of the treatment landscape limits the results regarding lines of therapy.

Conclusion

This large-scale study provides insight on characteristics of patients with RCC, and it highlights the need for better treatment options to improve survival.

考虑到肾细胞癌(RCC)的治疗形势发展迅速,英国近期缺乏对RCC人群的描述,也缺乏有关治疗和患者预后的真实数据。利用英国的国家数据集分析RCC患者的人口统计学和临床特征、治疗模式和总生存率。这是一项回顾性队列研究,使用人口统计学、临床、癌症登记和治疗数据对2014-2018年间确诊为RCC(所有分期)的患者进行研究。患者随访至死亡或研究结束(2020 年 12 月 31 日)。为了解治疗顺序,对每条线路的治疗方法进行了描述。采用 Kaplan-Meier 方法进行时间到事件分析。使用 Cox 比例危险模型确定了与停药和生存相关的因素。在纳入的32577名患者中,诊断时的中位年龄为66岁,63.4%为男性,6786人(20.8%)在诊断时患有转移性RCC。酪氨酸激酶抑制剂(TKI)单药疗法是最常见的治疗方法。超过四分之三的患者(78.5% [95% CI:78.0-78.9])在确诊一年后存活(在确诊时未转移的亚组中存活率为 93.2%,在确诊时有转移的患者中存活率为 37.1%)。在确诊时已转移的亚组中,18.0%的患者在确诊后三年仍存活。治疗领域的快速发展限制了有关治疗方法的结果。这项大规模研究深入揭示了RCC患者的特征,并强调需要更好的治疗方案来提高生存率。

Objectives

Patients with histologic subtype bladder cancer (HSBC) suffer worse outcomes than those with conventional urothelial carcinoma (UC). We sought to characterize the use of adjuvant chemotherapy (AC) in HSBC after radical cystectomy (RC) using the National Cancer Database (NCDB).

Materials and Methods

We retrospectively queried the NCDB (2006-2019) for patients with non-metastatic bladder cancer (BC) who underwent RC (N = 45,797). Patients were stratified by histologic subtype and receipt of AC. Multivariable logistic regression determined associations of demographic and clinicopathologic features with receipt of AC. Multivariable Cox regression evaluated associations between receipt of any AC and overall survival (OS).

Results

We identified 4,469 patients with HSBC classified as squamous, adenocarcinoma, small cell, sarcomatoid, micropapillary, or plasmacytoid. Squamous comprised 31% of the HSBC cohort, followed by small cells and micropapillary. Black patients were presented with a higher prevalence of adenocarcinoma (119/322, 37.0%). Use of AC was highest in plasmacytoid and small cell (30% each) and lowest in squamous (11%). Neuroendocrine histology was independently associated with greater odds of receiving AC (HR 1.6, 95% CI 1.37-1.87), while squamous cell histology was associated with lower odds (HR 0.61, 95% CI 0.53-0.71). On multivariable Cox regression analysis, treatment with AC was associated with significantly longer OS (HR 0.69, 95% CI 0.59-0.81) and for squamous, sarcomatoid, and micropapillary cohorts after stratified by subtype.

Conclusions

AC was variably used among patients with HSBC and was associated with OS benefit in such patients.

目的组织学亚型膀胱癌(HSBC)患者的预后比传统尿路上皮癌(UC)患者差。我们试图利用美国国家癌症数据库(NCDB)来描述根治性膀胱切除术(RC)后辅助化疗(AC)在 HSBC 患者中的应用。根据组织学亚型和接受 AC 的情况对患者进行了分层。多变量逻辑回归确定了人口统计学和临床病理学特征与接受 AC 的相关性。多变量 Cox 回归评估了接受任何 AC 与总生存期 (OS) 之间的关系。鳞状细胞癌占 HSBC 患者总数的 31%,其次是小细胞癌和微乳头状癌。黑人患者的腺癌发病率较高(119/322,37.0%)。浆细胞瘤和小细胞瘤使用 AC 的比例最高(均为 30%),鳞状细胞瘤使用 AC 的比例最低(11%)。神经内分泌组织学与接受 AC 的更高几率独立相关(HR 1.6,95% CI 1.37-1.87),而鳞状细胞组织学与更低几率相关(HR 0.61,95% CI 0.53-0.71)。在多变量 Cox 回归分析中,鳞状细胞、肉瘤样细胞和微乳头状细胞组群按亚型分层后,接受 AC 治疗与明显更长的 OS 相关(HR 0.69,95% CI 0.59-0.81)。

Background

Cabozantinib, an oral multi-targeted tyrosine kinase inhibitor (TKI), has demonstrated efficacy in metastatic renal cell carcinoma (mRCC). The association between toxicity and therapeutic effectiveness has been established with other TKIs. We investigated whether cabozantinib dose reductions, a surrogate for toxicity and adequate drug exposure, were associated with improved clinical outcomes in mRCC.

Methods

Employing the CKCis database, we analyzed patients treated with cabozantinib in the second line or later between 2011 to 2021. The cohort was stratified into those needing dose reductions (DR) during treatment and those not (no-DR). Outcomes, including objective response rate (ORR), time to treatment failure (TTF), and overall survival (OS), were compared based on dose reduction status. The influence of the initial dose on outcomes was also explored.

Results

Among 319 cabozantinib-treated patients, 48.3% underwent dose reductions. Response rates exhibited no significant difference between the DR and no-DR groups (15.1% vs. 18.2%, P = .55). Patients with DR had superior median OS (26.15 vs. 15.47 months, P = .019) and TTF (12.74 vs. 6.44 months, P = .022) compared to no-DR patients. These differences retained significance following adjustment for IMDC risk group (OS HR = 0.67, P = .032; TTF HR = 0.65, P = .008). There was no association between the initial dose and ORR, OS, or TTF.

Conclusion

This study highlights the link between cabozantinib dose reductions due to toxicity and improved survival and time to treatment failure in mRCC patients. These findings underscore the potential of using on-treatment toxicity as an indicator of adequate drug exposure to individualize dosing and optimize treatment effectiveness. Larger studies are warranted to validate these results and develop individualized strategies for cabozantinib when given alone or in combination with immunotherapy.

背景卡博赞替尼是一种口服多靶点酪氨酸激酶抑制剂(TKI),对转移性肾细胞癌(mRCC)具有疗效。毒性与疗效之间的关联已在其他TKIs中得到证实。我们研究了卡博替尼剂量的减少(毒性和充分药物暴露的替代指标)是否与 mRCC 临床预后的改善有关。方法利用 CKCis 数据库,我们分析了 2011 年至 2021 年期间接受卡博替尼二线或二线以上治疗的患者。队列分为治疗期间需要减量(DR)的患者和不需要减量(no-DR)的患者。根据减量状态比较了客观反应率(ORR)、治疗失败时间(TTF)和总生存期(OS)等结果。结果在319名接受卡博替尼治疗的患者中,48.3%的患者接受了减量治疗。DR组与无DR组的应答率无明显差异(15.1% vs. 18.2%,P = .55)。与非 DR 患者相比,DR 患者的中位 OS(26.15 个月 vs. 15.47 个月,P = .019)和 TTF(12.74 个月 vs. 6.44 个月,P = .022)更优。在调整 IMDC 风险组后,这些差异仍具有显著性(OS HR = 0.67,P = .032;TTF HR = 0.65,P = .008)。结论本研究强调了卡博替尼因毒性而减少剂量与改善mRCC患者生存率和治疗失败时间之间的联系。这些发现强调了将治疗中毒性作为充分药物暴露的指标来个体化剂量和优化治疗效果的潜力。我们需要进行更大规模的研究来验证这些结果,并为卡博替尼单独用药或与免疫疗法联合用药制定个体化策略。

Introduction

Enfortumab vedotin (EV) is an antibody–drug conjugate approved alone and in combination with pembrolizumab for advanced urothelial cancer (UC). EV-related-cutaneous-events (EVCEs) are common and rarely life-threatening. Black patients are frequently under-represented in oncology trials, and dermatologic conditions may vary with race.

Methods

Therefore, this retrospective analysis investigated differences in EVCE frequency between Black and White patients in an urban cohort (Johns Hopkins [JH]) and a US-based, nationwide electronic health record (EHR)-derived deidentified database (Flatiron Health [FH]) with sub-group analysis of those who had received prior pembrolizumab.

Results

The study included 12 Black patients in the JH Cohort (17.1%) and 24 Black patients in the FH Cohort (7.6%). In both cohorts, the frequency of EVCEs among Black patients was higher compared to White patients (JH: 66.7% vs. 33.3%; FH: 25.0% vs. 15.8%), though not statistically significant. In the larger FH Cohort EVCEs were significantly more common among Black compared to White patients treated with prior pembrolizumab (Odds Ratio [OR]: 4.76 [95%CI: 1.42, 15.95]) and recent pembrolizumab (within 90 days of EV initiation) (OR 9.00 [95%CI: 1.94, 41.66]).

Conclusion

This hypothesis-generating retrospective study, comprising the largest population of EV-treated Black patients reported to date, emphasizes the importance of attentiveness to EVCEs among Black patients, particularly with receipt of pembrolizumab.

导读:恩福妥单抗维多汀(EV)是一种抗体药物结合物,已被批准单独或与彭博利珠单抗联合用于晚期尿路上皮癌(UC)的治疗。与 EV 相关的切肤事件(EVCE)很常见,但很少危及生命。黑人患者在肿瘤试验中的代表性往往不足,而且皮肤病可能因种族而异。因此,这项回顾性分析调查了城市队列(约翰霍普金斯大学[JH])和美国全国范围内电子健康记录(EHR)衍生的去识别数据库(Flatiron Health [FH])中黑人和白人患者的EVCE频率差异,并对既往接受过pembrolizumab治疗的患者进行了亚组分析。在两个队列中,黑人患者发生 EVCE 的频率均高于白人患者(JH:66.7% 对 33.3%;FH:25.0% 对 15.8%),但无统计学意义。在更大的 FH 队列中,与白人患者相比,黑人患者中发生 EVCE 的比例明显更高(Odds Ratio [OR]:4.76 [95%CI:1.42, 15.95]),最近接受过彭博利珠单抗治疗(EV 开始后 90 天内)的患者中发生 EVCE 的比例也更高(OR 9.00 [95%CI:1.94, 41.66])。结论这项产生假设的回顾性研究是迄今为止报告的接受过EV治疗的黑人患者人数最多的一项研究,它强调了关注黑人患者EVCEs的重要性,尤其是在接受pembrolizumab治疗时。

Background

An estimated 20% to 30% of men with advanced prostate cancer carry a mutation in DNA damage repair genes, of which half are estimated to be germline. Eligibility criteria for germline genetic testing expanded significantly for Ontario patients in May 2021 and many centers adopted a “mainstream” model, defined as oncologist-initiated genetic testing.

Methods

We conducted a retrospective chart review to report on the first-year mainstream experience of a large tertiary oncologic center, the Sunnybrook Odette Cancer Centre. All patients who underwent mainstream at the discretion of their treating physician were included. A subset underwent somatic profiling as part of clinical trial screening. Descriptive statistics were used to report baseline clinicopathologic characteristics and treatments received.

Results

Between May 1, 2021, and May 30, 2022, 174 patients with prostate cancer underwent mainstream germline genetic testing with a 19-gene panel. Median age was 75 (IQR 68-80), and 82% of patients were diagnosed with either de novo metastatic or high-risk localized prostate adenocarcinoma. Fourteen patients (8%; 95% CI 4%-12%) were found to have a deleterious germline mutation, including pathogenic or likely pathogenic variants in BRCA1/2, ATM, CHEK2, PMS2, RAD51C, HOXB13, and BRIP1. Forty-nine patients (28%; 95% CI 21%-35%) were found to have a variant of uncertain significance. Thirty-four patients also had next-generation sequencing (NGS) of their somatic tissue. Among this subset, 8 of 34 (23%) had an alteration in homologous recombination repair (HRR) genes. Of the 14 patients with a germline mutation, none had a prior personal history of malignancy and 6 (43%) did not have any first- or second-degree relatives with history of prostate, pancreatic, breast, or ovarian cancer.

Conclusion

We report on the real-world characteristics of prostate cancer patients who underwent mainstream germline genetic testing. Personal history and family history of cancer cannot reliably stratify patients for the presence of pathogenic germline variants.

背景据估计,20% 到 30% 的晚期前列腺癌患者携带 DNA 损伤修复基因突变,其中一半是种系基因突变。2021 年 5 月,安大略省患者接受种系基因检测的资格标准大幅提高,许多中心采用了 "主流 "模式,即由肿瘤学家发起基因检测。所有由主治医生决定接受主流基因检测的患者都被纳入其中。作为临床试验筛选的一部分,一部分患者接受了体细胞分析。结果2021年5月1日至2022年5月30日期间,174名前列腺癌患者接受了19个基因面板的主流种系基因检测。中位年龄为 75 岁(IQR 68-80),82% 的患者被诊断为新发转移性或高危局部前列腺腺癌。发现14名患者(8%;95% CI 4%-12%)存在有害种系突变,包括BRCA1/2、ATM、CHEK2、PMS2、RAD51C、HOXB13和BRIP1中的致病变异或可能致病变异。49名患者(28%;95% CI 21%-35%)被发现存在意义不确定的变异。34 名患者还对其体细胞组织进行了下一代测序(NGS)。在这个子集中,34 人中有 8 人(23%)的同源重组修复(HRR)基因发生了改变。结论我们报告了接受主流种系基因检测的前列腺癌患者的实际特征。个人病史和癌症家族史不能可靠地对存在致病基因变异的患者进行分层。

Purpose

The study aimed to investigate the impact of adjuvant chemotherapy on time to recurrence (TTR) and overall survival (OS) in patients with histologic variants of upper tract urothelial carcinoma (VUTUC) following radical nephroureterectomy (RNU).

Materials and methods

A retrospective review of 131 VUTUC patients' medical records, from a pool of 368 non-metastatic localized or locally advanced UTUC cases, treated at a single tertiary referral center between January 2011 and January 2021. The intervention was adjuvant chemotherapy administration post-RNU. TTR and OS were evaluated using Kaplan-Meier and Cox proportional hazard regression, covariates adjusted for age, postoperative GFR, history of neoadjuvant chemotherapy, T and N stage with stabilized inverse probability of treatment weighting (sIPTW).

Results

The application of adjuvant chemotherapy showed a significant extension in TTR (P = .01), but no substantial impact on OS (P = .19) after sIPTW adjustment for covariates. Multivariate analysis revealed adjuvant chemotherapy, tumor size, and lymphovascular invasion as significant prognostic factors for TTR. In contrast, only tumor size and perineural invasion were significant for OS. Adjuvant chemotherapy reduced the progression risk in certain VUTUC subtypes (squamous or glandular/micropapillary), but not in sarcomatoid variants.

Conclusions

Adjuvant chemotherapy appears to improve TTR, albeit without a significant effect on OS, in nonmetastatic localized and locally advanced VUTUC patients post-RNU. While beneficial to some VUTUC subtypes, it did not yield significant advantages for sarcomatoid variants. Despite adjustments for known confounders, the study's findings may be subject to potential selection bias and unmeasured confounding factors.

该研究旨在探讨辅助化疗对根治性肾切除术(RNU)后上尿路上皮癌(VUTUC)组织学变异患者的复发时间(TTR)和总生存期(OS)的影响。该研究对2011年1月至2021年1月期间在一家三级转诊中心接受治疗的368例非转移性局部或局部晚期UTUC病例中的131例VUTUC患者的病历进行了回顾性研究。干预措施为RNU术后辅助化疗。采用Kaplan-Meier和Cox比例危险回归对TTR和OS进行了评估,并对年龄、术后GFR、新辅助化疗史、T期和N期进行了协变量调整,采用稳定的逆治疗概率加权(sIPTW)。辅助化疗可显著延长TTR(p=0.01),但经sIPTW调整协变量后,对OS无实质性影响(p=0.19)。多变量分析显示,辅助化疗、肿瘤大小和淋巴管侵犯是TTR的重要预后因素。相比之下,只有肿瘤大小和神经周围侵犯对OS有显著影响。辅助化疗降低了某些VUTUC亚型(鳞状或腺/微乳头状)的进展风险,但对肉瘤样变异型没有影响。辅助化疗似乎可以改善RNU后非转移性局部和局部晚期VUTUC患者的TTR,尽管对OS没有显著影响。虽然辅助化疗对某些VUTUC亚型有益,但对肉瘤变异型并无明显优势。尽管对已知的混杂因素进行了调整,但研究结果仍可能受到潜在的选择偏差和未测量混杂因素的影响。本研究评估了辅助化疗对131例变异组织学上尿路上皮癌(VUTUC)患者术后复发和生存期的影响。通过使用 Kaplan-Meier 和 Cox 回归及 sIPTW 调整,结果显示辅助化疗对复发时间有显著益处,但对总生存期无显著益处。

Introduction

The role of local definitive therapy in addition to systemic treatment in clinically positive regional lymph node (cN+) bladder cancer is yet to be determined. Herein, we sought to investigate the role of radical cystectomy (RC) in management of patients with cN+ bladder cancer at US Veterans Health Administration Facilities.

Methods

We identified patients diagnosed with cN+ bladder cancer between 2000-2017 using the Department of Veterans Affairs (VA) Informatics and Computing Infrastructure (VINCI). We employed a combination of database/registry coded values and chart review for data collection. To minimize mortality bias, we excluded patients who died within 90 days of diagnosis. We divided the patients into cystectomy (C) versus “no cystectomy” (NOC) cohorts. Propensity score matching was performed based on predictors of undergoing RC. Multivariable Cox models and Kaplan-Meier survival curves were used to estimate overall survival (OS) and cancer specific survival (CCS).

Result

After matching, 158 patients were included in the C and NOC groups. In the C-group, 85(54%) patients received pre-cystectomy chemotherapy, and 73(46%) patients underwent post-cystectomy chemotherapy. In the C-group, 65(41%) patients and in the NOC-group, 66(42%) patients had clinical N1 disease (P = .77). In multivariable Cox model, undergoing RC was associated with improved OS (HR0.62; 95%CI 0.47-0.81), P < .001) and CSS (HR0.58; 95%CI 0.42-0.80; P < .001).

Conclusion

As part of multimodal treatment, undergoing RC was associated with improved OS and CSS in subset of patients with cN+ bladder cancer. Prospective randomized trials are warranted to further investigate the role of local definitive therapy in this specific patient population.

导言:对于临床上区域淋巴结(cN+)阳性的膀胱癌患者,除全身治疗外,局部确定性治疗的作用尚未确定。在此,我们试图研究根治性膀胱切除术(RC)在美国退伍军人卫生管理局设施对 cN+ 膀胱癌患者的治疗中的作用。我们采用数据库/注册表编码值和病历审查相结合的方法收集数据。为尽量减少死亡率偏差,我们排除了诊断后 90 天内死亡的患者。我们将患者分为膀胱切除术(C)和 "无膀胱切除术"(NOC)两组。根据接受 RC 的预测因素进行倾向评分匹配。采用多变量 Cox 模型和 Kaplan-Meier 生存曲线估算总生存期(OS)和癌症特异性生存期(CCS)。在C组中,85例(54%)患者接受了子宫切除术前化疗,73例(46%)患者接受了子宫切除术后化疗。在C组中,65(41%)名患者和NOC组中,66(42%)名患者患有临床N1疾病(P = .77)。在多变量 Cox 模型中,接受 RC 与 OS(HR0.62;95%CI 0.47-0.81)和 CSS(HR0.58;95%CI 0.42-0.80;P <;.001)的改善有关。有必要进行前瞻性随机试验,以进一步研究局部明确疗法在这一特殊患者群体中的作用。

Introduction

Baseline sarcopenia and postoperative changes in muscle mass are independently associated with overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) undergoing cytoreductive nephrectomy (CN). Here we examine the relationships between preoperative (baseline), postoperative changes in muscle quantity, and survival outcomes following CN as determined by linear segmentation, a clinic-friendly tool that rapidly estimates muscle mass.

Materials and Methods

Our nephrectomy database was reviewed for patients with metastatic disease who underwent CN for RCC. Linear segmentation of the bilateral psoas/paraspinal muscles was completed for baseline imaging within 60 days of surgery and imaging 30 to 365 days postoperatively. Kruskal-Wallis for numerical and Fisher's exact test for categorical variables were used to test for differences between groups according to percent change in linear muscle index (LMI, cm2/m2). Multivariable Cox proportional hazards models evaluated associations between LMI percent change and cancer-specific (CSM) and all-cause mortality (ACM). Kaplan Meier curves estimated cancer-specific (CSS) and overall survival (OS).

Results

From 2004-2020, 205 patients were included of whom 52 demonstrated stable LMI (25.4%; LMI change < 5% [0Δ]), 60 increase (29.3%; LMI +5% [+Δ]), and 92 decrease (44.9%; LMI -5% [-Δ]). Median time from baseline imaging to surgery was 18 days, and time from surgery to postoperative imaging was 133 days. Median CSS and OS were highest among patients with 0Δ LMI (CSS: 133.6 [0Δ] vs. 61.9 [+Δ] vs. 37.4 [-Δ] months; P = .0018 || OS: 67.2 [0Δ] vs. 54.8 [+Δ] vs. 29.5 [-Δ] months; P = .0007). Stable LMI was a protective factor for CSM (HR 0.48; P = .024) and ACM (HR 0.59; P = .040) on multivariable analysis.

Discussion

Change in muscle mass after CN, as measured by the linear muscle segmentation technique, is independently associated with OS and CSS in patients following CN. Of note, lack of change was associated with longer survival.

接受细胞切除肾切除术(CN)的转移性肾细胞癌(mRCC)患者的基线肌肉疏松症和术后肌肉量变化与总生存期(OS)有独立关联。在此,我们研究了术前(基线)、术后肌肉量变化与CN术后生存结果之间的关系,这些变化是通过线性分割法确定的,这是一种方便临床使用的工具,可快速估算肌肉量。我们对肾切除术数据库中因 RCC 而接受 CN 治疗的转移性疾病患者进行了审查。在手术后 60 天内的基线成像和术后 30-365 天的成像中完成了双侧腰肌/脊柱旁肌的线性分割。数字变量采用 Kruskal-Wallis 检验,分类变量采用费雪精确检验,根据线性肌肉指数(LMI,cm/m)的百分比变化检验组间差异。多变量考克斯比例危险模型评估了线性肌肉指数百分比变化与癌症特异性死亡率(CSM)和全因死亡率(ACM)之间的关系。卡普兰-麦尔曲线估算了癌症特异性生存率(CSS)和总生存率(OS)。2004-2020 年间,共纳入 205 例患者,其中 52 例患者的 LMI 保持稳定(25.4%;LMI 变化 <5% [0Δ]),60 例患者的 LMI 增加(29.3%;LMI +5% [+Δ]),92 例患者的 LMI 减少(44.9%;LMI -5% [-Δ])。从基线成像到手术的中位时间为 18 天,从手术到术后成像的时间为 133 天。LMI 为 0Δ 的患者的 CSS 中位数和 OS 中位数最高(CSS:133.6 [0Δ] vs. 61.9 [+Δ] vs. 37.4 [-Δ] 个月;P=0.0018 || OS:67.2 [0Δ] vs. 54.8 [+Δ] vs. 29.5 [-Δ] 个月;p=0.0007)。在多变量分析中,稳定的 LMI 是 CSM(HR 0.48;p=0.024)和 ACM(HR 0.59;p=0.040)的保护因素。通过线性肌肉分割技术测量的CN术后肌肉质量变化与CN术后患者的OS和CSS独立相关。值得注意的是,无变化与更长的生存期相关。微摘要:评估和选择患者是确定最有可能从细胞肾切除术中获益的患者的关键。我们假设,根据横断面成像评估术前至术后肌肉量的临床友好型工具,肌肉量的动态变化可预测存活率。肌肉量增加或稳定的患者总生存期和癌症特异性生存期更长,这是一个重要的考虑因素。
