摘要

目的多药新辅助化疗（NAC）后盆腔淋巴结转移（ypN+）是非转移性肌浸润性膀胱癌（nmMIBC）的不良预后征象。我们试图创建一个提名图，预测 cN0 nmMIBC NAC 后出现 ypN+ 的概率，并确定其与总生存期（OS）的关系。方法与材料我们查阅了国家癌症数据库中 2004 年至 2020 年接受多药 NAC 和手术治疗的 cT2-4N0M0 膀胱尿路上皮癌患者的数据。数据分割后，单变量逻辑回归确定了与 ypN+ 相关的变量，P < .05。符合条件的变量被用于多变量逻辑回归和生成提名图。95% 灵敏度阈值定义了 ypN+ 的高风险组和低风险组。Fine-Gray 模型评估了 ypN+ 风险组别和 OS，并考虑了手术死亡率的竞争风险。结果共确定了 6194 例患者，中位随访时间为 39.5 个月（四分位间距 [IQR]，20.5-67.2 个月）。大多数患者为高级别（97.7%）cT2 疾病（70.8%），非乳头状尿路组织学（67.3%），确诊后中位 41.0 天（IQR，28.0-59.0 天）开始接受 NAC。该提名图包括年龄（以十年为单位）（几率比[OR]，0.94；95% 置信区间[CI]，0.87-1.03；P = .172）、从诊断到 NAC 的周数（OR，1.02；95% CI，1.01-1.04；P = .004）、非乳头组织学（OR，1.17；95% CI，0.99-1.39；P = .068）和临床 T 分期。在检测队列中，392 例（22.8%）高危患者和 12 例（8.0%）低危患者中发现了 ypN+（P <.001），中位 OS 分别为 36.1 个月和 74.0 个月（P <.001）。尽管存在 30 天（亚分布危险比 [SHR]，1.80；95% CI，1.49-2.18；P < .001）和 90 天手术死亡率（SHR，1.68；95% CI，1.39-2.04；P < .001）的竞争风险，但高风险患者的 OS 更差。结论这是第一项为主要为高级别nmMIBC提供预测ypN+和预后较差OS的工具的研究，可以选择患者进行替代性新辅助治疗，并促进未来的研究。

A Predictive Nomogram for Development of Lymph Node Metastasis in Muscle-Invasive Bladder Cancer Following Neoadjuvant Therapy

Purpose

Pelvic lymph node metastases (ypN+) after multiagent neoadjuvant chemotherapy (NAC) is a poor prognostic sign in nonmetastatic muscle-invasive bladder cancer (nmMIBC). We sought to create a nomogram predicting probability of ypN+ after NAC for cN0 nmMIBC and determine association with overall survival (OS).

Methods and Materials

We reviewed the National Cancer Database for patients with cT2-4N0M0 urothelial carcinoma of the bladder receiving multiagent NAC and surgery from 2004 to 2020. Following a data split, univariate logistic regression identified variables associated with ypN+ at P < .05. Eligible variables were used for multivariate logistic regression and nomogram generation. A threshold for 95% sensitivity defined high- and low-risk groups for ypN+. Fine–Gray models assessed ypN+ risk group and OS, accounting for competing risks of surgical mortality.

Results

A total of 6194 patients were identified with a median follow-up of 39.5 months (interquartile range [IQR], 20.5-67.2 months). Most patients had high-grade (97.7%) cT2 disease (70.8%) with nonpapillary urothelial histology (67.3%) and initiated NAC at a median of 41.0 days after diagnosis (IQR, 28.0-59.0 days).The nomogram included age in decades (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.87–1.03; P = .172), weeks from diagnosis to NAC (OR, 1.02; 95% CI, 1.01-1.04; P = .004), nonpapillary histology (OR, 1.17; 95% CI, 0.99-1.39; P = .068), and clinical T-stage. Within the testing cohort, ypN+ was found in 392 (22.8%) high-risk and 12 (8.0%) low-risk patients (P < .001), with median OS of 36.1 and 74.0 months, respectively (P < .001). High-risk patients had worse OS despite competing risks of 30-day (subdistribution hazard ratio [SHR], 1.80; 95% CI, 1.49-2.18; P < .001) and 90-day surgical mortality (SHR, 1.68; 95% CI, 1.39-2.04; P < .001).

Conclusions

This is the first study to provide a tool for predicting ypN+ and prognosticate worse OS in primarily high-grade nmMIBC and could select patients for alternative neoadjuvant therapy and facilitate future study.
