Robot-assisted Minimally Invasive Thoraco-laparoscopic Esophagectomy Versus Open Transthoracic Esophagectomy for Resectable Esophageal Cancer. The ROBOT-trial: a Monocenter Randomized Controlled Trial.
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
Interventional
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Postoperative complications modified Clavien-Dindo classification (MCDC) grade 2 and higher
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)
Participants will be followed for the duration of hospital stay, an expected average of 2 weeks
