Totally Versus Hybrid Minimally Invasive Esophagectomy for Esophageal Cancer

Official title

Totally Versus Hybrid Minimally Invasive Esophagectomy for Esophageal Cancer - A Multicentric Phase III Prospective Randomized Controlled Trial

Overview

Esophageal and gastroesophageal junction cancers remain associated with poor survival despite progress in multimodal treatment. Surgery, especially Ivor-Lewis esophagectomy, combined with peri-operative therapy improves survival but is burdened by major morbidity, mainly respiratory and anastomotic complications, which compromise recovery and adjuvant treatment. Minimally invasive approaches such as totally minimally invasive esophagectomy (TMIE) have shown potential to reduce postoperative morbidity compared to the hybrid approach (HE). However, existing studies are heterogeneous, mostly retrospective, and insufficient to establish a standard. This trial aims to provide high-level evidence comparing TMIE to HE, including robotic techniques, with integrated analyses of clinical outcomes, quality of life, and health economics.

Interventions

• Procedure Totally Minimally Invasive Esophagectomy (TMIE)
  All patients will undergo an Ivor-Lewis procedure with the same laparoscopic abdominal approach. The thoracic approach differs between the two groups: HE with open thoracotomy in the 5th or 6th intercostal space and TMIE with thoracoscopic approach. The main aspects of the surgical technique will be standardized. All patients will receive a transthoracic en-bloc esophagectomy with termino-lateral or latero-lateral anastomosis in the upper chest, including an abdominal lymphadenectomy (left and r
