Overview
Brief Summary
This is the first randomized controlled trial designed to compare robot-assisted minimally invasive thoraco-laparoscopic esophagectomy with open transthoracic esophagectomy as surgical treatment for resectable esophageal cancer.
If our hypothesis is proved correct, robot-assisted minimally invasive thoraco-laparoscopic esophagectomy will result in a lower percentage of postoperative complications, lower blood loss, shorter hospital stay, but with at least similar oncologic outcomes and better postoperative quality of life compared with the open transthoracic esophagectomy (current standard).
Detailed Description
Rationale: As stated in the 2010 revised Dutch esophageal carcinoma guidelines, the golden standard for surgical treatment of esophageal carcinoma is open transthoracic esophagectomy. Recent evidence suggests that robot-assisted thoraco-laparoscopic esophagectomy using the Da Vinci ® robot can provide an extensive resection, with possibly better or at least equal radical (R0) resection rates and an equal number of dissected lymph nodes. This is accompanied with markedly reduced blood loss and reduction of overall complications with shorter intensive care unit (ICU) and hospital stay. Therefore, the robot-assisted thoraco-laparoscopic esophagectomy is now at a stage that it should be compared to the current standard of care in a randomized controlled trial. Objective: Evaluate the benefits, risks and costs of robot-assisted thoraco-laparoscopic esophagectomy as an alternative to open transthoracic esophagectomy as treatment for esophageal cancer. Study design: Randomized controlled parallel-group superiority trial Study population: Patients (age ≥ 18 and ≤ 75 jaar) with histologically proven surgically resectable (cT1-4a, N0-3, M0) squamous cell carcinoma, adenocarcinoma or undifferentiated esophageal carcinoma of the intrathoracic esophagus with European Clinical Oncology Group (ECOG) status 0, 1 or 2. Intervention: 112 patients will be randomly allocated to either A) robot-assisted thoraco-laparoscopic esophagectomy (n=56) or B) open transthoracic esophagectomy (n=56). Patients will receive the following interventions: Group A. Robot-assisted thoraco-laparoscopic esophagectomy, with gastric conduit formation. Group B. Open transthoracic esophagectomy, with gastric conduit formation. Main study parameters/endpoints: Primary outcome is the percentage of overall complications (Grade 2 and higher) as stated by the modified Clavien-Dindo classification (MCDC). Secondary outcomes are individual components of the primary endpoint (major and minor complications), (in hospital) mortality within 30 and 60 days, R0 resections, operation related events, postoperative recovery, oncologic outcomes, cost-effectiveness and quality of life. Follow-up: 60 months after randomization

Outcomes
Primary Outcomes
Postoperative complications modified Clavien-Dindo classification (MCDC) grade 2 and higher
Time Frame: Participants will be followed for the duration of hospital stay, an expected average of 2 weeks
The primary outcome of this study is the percentage of overall complications (Grade 2 and higher) as stated by the modified Clavien-Dindo classification of surgical complications (MCDC)
