Abstrakt: Background: The prognosis for patients with esophageal cancer who received neoadjuvant chemoradiotherapy (nCRT) followed by surgery has shown improvement in recent years. We sought to identify the critical factors contributing to enhanced survival outcomes. Patients and Methods: We retrospectively examined 427 patients with esophageal cancer treated with nCRT and esophagectomy across two periods: P1 (from 1 January 2004 to 31 December 2011) and P2 (from 1 January 2012 to 31 December 2017). The introduction of the CROSS regimen and total meso-esophagectomy in P2 prompted an evaluation of their effects on perioperative outcomes and overall survival (OS). Results: During P2, the occurrence of recurrent laryngeal nerve palsy increased significantly from 3.9 to 16.8% (p < 0.001), while pneumonia and in-hospital mortality rates remained unchanged. The median OS improved from 19.2 to 29.2 months (p < 0.001) between P1 and P2. Multivariable analysis identified higher nodal yields and the achievement of major response as favorable prognostic factors. Conversely, an involved circumferential resection margin (CRM), an advanced ypN stage, and pneumonia were independently associated with poor outcomes. Patients treated during P2 had a lower prevalence of involved CRM (10% vs. 25.1%, p < 0.001), a higher rate of major response (52.7% vs. 34.8%, p < 0.01), and a greater nodal yield (27.8 vs. 10.9, p < 0.001). Conclusions: The clinical outcomes following nCRT and surgery have improved significantly over time. This progress can be attributed to multiple factors, with the primary drivers being the refinement of nCRT protocols and the application of radical surgery. [ABSTRACT FROM AUTHOR]
