摘要
中文
手术和放化疗(CRT)是临床I期食管鳞状细胞癌(ESCC)的标准治疗选择。JCOG0502是一项多中心、非随机、平行组比较研究,证明了根治性CRT在cT1bN0M0 ESCC患者的总生存期(OS)方面非劣于手术;然而,机构差异可能影响结局。本研究探讨了JCOG0502患者中生存率和不良事件(AEs)的机构间异质性。在379例入组患者中,364例被分析。入组≥13例患者的机构(对应于机构试验入组的中位数)被归类为高入组机构(High),而入组<13例的机构被归类为低入组机构(Low)。机构试验入组量被评估为探索性指标,而非机构病例量或手术量的直接衡量。主要终点是OS。次要终点是无进展生存期(PFS)和AEs。在手术组中,机构试验入组量与OS无显著关联(High与Low的HR为0.73;95% CI,0.40-1.35)。类似地,在CRT组中未观察到显著关联(HR,1.12;95% CI,0.59-2.13)。PFS的结果与两组中的这些OS结果一致。心肌缺血或梗死发生在CRT组的5例Low患者中,High中没有。在手术组或CRT组中,机构试验入组量与生存结局之间未发现明确关联。然而,不能排除临床上意义的差异。观察到的某些毒性(包括心肌缺血)的差异应被视为假设产生性的。

Surgery and chemoradiotherapy (CRT) are standard options for clinical stage I esophageal squamous cell carcinoma (ESCC). JCOG0502, a multicenter, non-randomized, parallel-group comparison, demonstrated the non-inferiority of definitive CRT compared with surgery for overall survival (OS) in patients with cT1bN0M0 ESCC; however, institutional differences may influence outcomes. This study explored inter-institutional heterogeneity in survival and adverse events (AEs) among patients in JCOG0502. Among 379 enrolled patients, 364 were analyzed. Institutions enrolling ≥ 13 patients, corresponding to the median institutional trial enrollment, were classified as high-enrollment institutions (High), whereas those enrolling < 13 patients were classified as low-enrollment institutions (Low). Institutional trial enrollment was evaluated as an exploratory indicator, rather than as a direct measure of institutional case or procedural volume. The primary endpoint was OS. Secondary endpoints were progression-free survival (PFS) and AEs. In the surgery group, institutional trial enrollment volume was not significantly associated with OS (HR for High vs. Low, 0.73; 95% CI, 0.40-1.35). Similarly, no significant association was observed in the CRT group (HR, 1.12; 95% CI, 0.59-2.13). Findings for PFS were consistent with these OS results in both groups. Myocardial ischemia or infarction occurred in 5 patients in Low and none in High in the CRT group. No clear association was identified between institutional trial enrollment volume and survival outcomes in either the surgery or CRT group. However, clinically meaningful differences could not be excluded. The observed differences in selected toxicities, including myocardial ischemia, should be considered hypothesis-generating.
