Robotic-assisted Esophagectomy vs. Video-Assisted Thoracoscopic Esophagectomy(REVATE) Trial

June 28, 2021 updated by: Chang Gung Memorial Hospital

Robotic-assisted Esophagectomy vs. Video-Assisted Thoracoscopic Esophagectomy(REVATE) : a Multicenter Open-label Randomized Controlled Trial

The investigators will assess the adequacy of nodal dissection along the recurrent laryngeal nerve performed with robot-assisted versus video-assisted thoracoscopic esophagectomy in patients with esophageal squamous cell carcinoma through a prospective multicentre randomized study design.

Detailed Description

Radical lymph node dissection (LND) along the recurrent laryngeal nerve (RLN) is surgically demanding and can be associated with substantial postoperative morbidity. The question as to whether robot-assisted esophagectomy (RE) might be superior to video-assisted thoracoscopic esophagectomy (VATE) for performing LND along the RLN in patients with esophageal squamous cell carcinoma (ESCC) remains open.

The investigators will conduct a multicenter, open-label, randomized controlled trial (termed REVATE) enrolling patients with ESCC scheduled to undergo LND along the RLN. Patients will be randomly assigned to either RE or VATE. The primary outcome measure will be the rate of unsuccessful LND along the left RLN, which will be defined as 1) failure to remove lymph nodes along the left RLN or 2) occurrence of left RLN palsy following LND. Secondary outcomes will include the number of successfully removed RLN nodes, postoperative recovery, length of hospital stay, 30- and 90-day mortality, quality of life, and oncological outcomes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of unsuccessful LND along the left RLN
Time Frame: Till 6 months postoperatively
Regardless of the presence of hoarseness, vocal cord function will be assessed by an experienced otolaryngologist using a nexile laryngoscope within one week of surgery. RLN palsy will be classified according to the following variables: site (unilateral versus bilateral); duration (temporary [i.e., recovering within 6 months] versus permanent [i.e. not recovering within 6 months]); and type of treatment required (type I: no therapy required; type II: injury requiring an elective surgical procedure; type III: injury requiring an urgent surgical procedure)
Till 6 months postoperatively

Secondary Outcome Measures

Outcome Measure

A sum score of 2 points or higher, of which at least 1 point is assigned because of infiltrative findings on pulmonary radiography, indicates the presence of pneumonia.

Hospital Anxiety and Depression Scale (HADS)
Time Frame: pre-operative < 5 days and 4 weeks, 3/6 months and yearly up to 5 years post-operatively.
The HADS aims to measure symptoms of anxiety and depression and consists of 14 items,seven items for the anxiety subscale and seven for the depression subscale. The questionnaire responses were analysed in the light of the results of this estimation of the severity of both anxiety and of depression. This enabled a reduction of the number of items in the questionnaire to just seven reflecting anxiety and seven reflecting depression.(Of the seven depression items five reflected aspects of reduction in pleasure response). Each item had been answered by the patient on a four point (0-3) response category so the possible scores ranged from 0 to 21 for anxiety and 0 to 21 for depression. a score of 0 to 7 for either subscale could be regarded as being in the normal range, a score of 11 or higher indicating probable presence ('caseness') of the mood disorder and a score of 8 to 10 being just suggestive of the presence of the respective state.
pre-operative < 5 days and 4 weeks, 3/6 months and yearly up to 5 years post-operatively.
European Organisation for Research and Treatment of Cancer(EORTC) QLQ-C30 , QLQ-OES18
Time Frame: pre-operative < 5 days and 4 weeks, 3/6 months and yearly up to 5 years post-operatively.
The EORTC QLQ-C30 incorporates a range of QOL issues in five functional scales (physical, role, cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea/vomiting), a global health/QOL scale, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The EORTC QLQ-OES18 contains four symptom scales (dysphagia, eating disorders, reflux, and pain) and six single items (difficulty swallowing saliva, choking, dry mouth, taste disorder, cough, and speech-related issues). Each question has four response choices ranging from 1 (not at all) to 4 (very much), except for the global QOL scale, which has seven response options ranging from 1 (very poor) to 7 (excellent). All questionnaire responses are linearly transformed to scores from 0 to 100.
pre-operative < 5 days and 4 weeks, 3/6 months and yearly up to 5 years post-operatively.
