P1.110. Overexpression of DTL Relates to Tumor Cell Proliferation and Malignant Outcome of Esophageal Squamous Cell Carcinoma

Abstract Topic Esophageal Cancer: Molecular Biology/Pathology Background Comparative genomic hybridization (CGH) method has contributed to the analysis of amplification and deletion of various genes. We detected Denticleless E3 ubiquitin protein ligase homolog (DTL) using the Agi...

P1.112. Low Circulating miR-5193 Promotes PD-L1–mediated Immune Evasion and Predicts Immune Checkpoint Inhibitor Response in Esophageal Cancer

Abstract Topic Esophageal Cancer: Molecular Biology/Pathology Background Low levels of circulating tumor-suppressor microRNAs are associated with cancer progression and poor prognosis. However, their role in immune evasion and response to immune checkpoint inhibitors (ICIs) remai...

P1.182. Development of Difficulty Prediction Method for Mediastinoscopic Esophagectomy in Esophageal Cancer

Abstract Topic Esophageal Cancer: Surgical Treatment of Esophageal Cancer Background Mediastinoscopic esophagectomy is a minimally invasive procedure for esophageal cancer, but no established method exists to predict surgical difficulty. This study aimed to identify a difficulty...

P1.215. Segmental Loss of Signal on Continuous Intraoperative Nerve Monitoring Predicts Postoperative Pneumonia After Transmediastinal Esophagectomy

Abstract Topic Esophageal Cancer: Surgical Treatment of Esophageal Cancer – early outcomes and complications Background Recurrent laryngeal nerve paralysis (RLNP) is a well-known risk factor for postoperative pneumonia in esophageal cancer surgery. Transmediastinal esophagectomy,...
