PD05.07. Enhancing SAM-Med3D with Prototype-Contrast Boundary Optimization for Esophageal Squamous Cell Carcinoma Segmentation

Esophageal Cancer: Other Precise segmentation of esophageal squamous cell carcinoma (ESCC) lesions on CT imaging is essential for treatment planning. While the Segment Anything Model for 3D medical images (SAM-Med3D) shows promise, its performance in delineating tumor boundaries remains suboptimal. We prop...

PD09.07. Impact of Type 2 Diabetes on Outcomes of Neoadjuvant Therapy and Surgery for Esophageal Cancer: A Multi-Center Retrospective Study

Esophageal Cancer: Surgical Treatment of Esophageal Cancer – early outcomes and complications The prognostic impact of type 2 diabetes in esophageal cancer patients receiving neoadjuvant therapy followed by surgery remains unclear. We evaluated its association with perioperative outcomes and long-term surv...

P1.155. Impact of Lymphaticvessel Invasion on Prognosis in Patients With Esophageal Squamous Cell Carcinoma Undergoing Neoadjuvant Immunochemotherapy: A Multicenter Retrospective Study

Esophageal Cancer: Surgical Treatment of Esophageal Cancer Prognostic stratification remains inadequate in patients with locally advanced esophageal squamous cell carcinoma (ESCC) following neoadjuvant immunotherapy combined with chemotherapy (NICT). This multicenter study aimed to determine the prognostic...

P1.066. Prognostic Equivalence of ypN and pN Staging in Esophageal Cancer After Neoadjuvant Therapy: A Multicenter Cohort Study of 2,545 Patients

Esophageal Cancer: Surgical Treatment of Esophageal Cancer Current staging systems apply ypN and pN categories interchangeably after neoadjuvant therapy plus esophagectomy; however, their prognostic equivalence has not been rigorously established. We investigated whether ypN0–3 confers equivalent disease-f...

P1.071. Perioperative Patient-Reported Outcomes After Robot-Assisted Versus Conventional Minimally Invasive Esophagectomy for Esophageal Squamous Cell Carcinoma: A Propensity Score-Matched Analysis

Findings support RAMIE as a viable alternative with comparable patient-centered outcomes, though the higher anastomotic leak rate warrants further investigation.

P1.067. Multinational Comparison of Surgical Approaches and Postoperative Outcomes in Esophageal Cancer: An International Multicenter Cohort Study

A retrospective analysis of a prospectively maintained international multicenter database comprising 2,490 patients who underwent curative-intent esophagectomy across four centers found three-field lymphadenectomy uniquely confers high recurrent laryngeal nerve palsy and chylothorax rates despite low mortality.

P1.072. Impact of Neoadjuvant Therapy on Survival After Esophagectomy for Squamous Cell Carcinoma: An International Multicenter Propensity Score Analysis

In this international multicenter analysis of 2,449 ESCC patients, neoadjuvant therapy was not associated with improved survival after esophagectomy and remained an independent predictor of worse OS and DFS across univariate, multivariable, PSM, and IPTW analyses.

PD02.06. The ``Invisible Cost'' After Minimally Invasive Esophagectomy: Clinical Characteristics, Survival Impact, and Intervention Timing for Patients with Persistent Moderate-to-Severe Symptoms

Symptom persistence does not adversely affect overall survival; its association with improved DFS likely reflects the tumor-control benefit of adjuvant therapy.

PD08.07. Multimodal AI-Driven Postoperative Surveillance for Oesophageal Cancer: Automated Patient-Reported Outcome Assessment and Early Complication Warning in a Prospective Study

An end-to-end multimodal AI system can accurately automate PRO assessment from natural patient conversations and provide clinically meaningful early warning for postoperative complications, with external validation confirming generalisability across cohorts.

P1.070. Exploring the Association Between Month of Esophagectomy and Long-Term Survival Outcomes : a Large-Scale Survival Study Combined Questionnaire Survey Analysis

Surgical timing, particularly esophagectomy performed in February, is associated with inferior long-term survival in ESCC patients, and concurrent low burnout levels during this period suggest that reduced surgical volume and altered case selection during the holiday season, rather than staff fatigue, may underlie this...

P1.064. Limitations of Preoperative Prediction Models for Complications After Esophagectomy: A Multi-Center Analysis

Standard preoperative variables are insufficient for individualized risk stratification of RLNP, anastomotic leak, or vocal cord palsy after esophagectomy, and improved prediction will require prospective integration of real-time intraoperative data.
