摘要
研究背景本研究旨在分析接受新辅助化疗(neoCTX)的cT1N0膀胱小细胞神经内分泌癌(SCNEC)患者的生存结果和病理反应:cT1N0 的定义是经尿道切除病理显示膀胱固有层受侵,且存在未受累的固有肌。对病理降期和复发进行了评估。采用 Cox 回归法和 Kaplan-Meier 法分析无病生存期(DFS)和总生存期(OS):结果:共纳入30例cT1N0膀胱SCNEC患者。中位随访时间为88个月[95%置信区间(CI)44-131个月]。21例(70%)患者接受了NeoCTX治疗,中位数为4个周期(1-6个周期不等)。共有 27 例(90%)患者接受了明确的局部治疗。在 cT1 膀胱 SCNEC 中,neoCTX 与病理分期上升几率降低 [几率比 = 0.07 (95% CI 0.01-0.45), P = 0.004]、复发几率降低 [几率比 = 0.12 (95% CI 0.02-0.65), P = 0.01],改善 DFS [危险比 (HR) 0.30, 95% CI 0.09-0.96, P = 0.04],改善 OS (HR 0.32, 95% CI 0.10-1.02, P = 0.05)。与接受新CTX治疗的cT2N0相比,接受新CTX治疗的cT1N0的中位DFS有所改善(HR 0.44,95% CI 0.19-1.03,P = 0.05),中位OS有所改善(HR 0.52,95% CI 0.22-1.24,P = 0.14):结论:NeoCTX对cT1膀胱SCNEC患者有提示性益处,可降低病理分期和转移复发的几率,并提高生存率。
Impact of systemic therapy on clinical T1 small-cell neuroendocrine carcinoma of the bladder
Background
The purpose of this study was to analyze survival outcomes and pathologic response of patients with cT1N0 small-cell neuroendocrine carcinoma (SCNEC) of the bladder treated with neoadjuvant chemotherapy (neoCTX).
Materials and methods
All cases of bladder SCNEC treated at our institution from January 1996 to July 2023 were identified. cT1N0 was defined as transurethral resection pathology showing lamina propria invasion with present and uninvolved muscularis propria. Pathologic downstaging and recurrences were evaluated. Disease-free survival (DFS) and overall survival (OS) were analyzed using the Cox regression and Kaplan–Meier method.
Results
A total of 30 patients with cT1N0 bladder SCNEC were included. Median follow-up was 88 months [95% confidence interval (CI) 44-131 months]. NeoCTX was given to 21 (70%) patients with a median of 4 cycles (range 1-6 cycles). A total of 27 (90%) patients received definitive local therapy. In cT1 bladder SCNEC, neoCTX was associated with decreased odds of pathologic upstaging [odds ratio = 0.07 (95% CI 0.01-0.45), P = 0.004], decreased odds of relapse [odds ratio = 0.12 (95% CI 0.02-0.65), P = 0.01], improved DFS [hazard ratio (HR) 0.30, 95% CI 0.09-0.96, P = 0.04], and improved OS (HR 0.32, 95% CI 0.10-1.02, P = 0.05). Compared with cT2N0 treated with neoCTX, cT1N0 treated with neoCTX had improved median DFS (HR 0.44, 95% CI 0.19-1.03, P = 0.05) and improved median OS (HR 0.52, 95% CI 0.22-1.24, P = 0.14).
Conclusions
NeoCTX had suggestive benefit in patients with cT1 bladder SCNEC with decreased odds of pathologic upstaging, metastatic relapse, and improved survival.
