Background: In the West, patients with cervical lymph node metastasis of resectable esophageal cancer at diagnosis are generally precluded from curative treatment. This study prospectively explored the safety and feasibility of neoadjuvant chemoradiotherapy followed by robot-assisted minimally invasive esophagectomy (RAMIE) with three-field lymphadenectomy for these patients., Methods: Between 2015 and 2021, patients with resectable thoracic esophageal cancer and cervical lymph node metastasis were recruited nationwide in the Netherlands. Patients without interval metastasis following neoadjuvant chemoradiotherapy and good physical condition underwent RAMIE with bilateral three-field lymphadenectomy. Safety was predefined as ≤50% Clavien-Dindo grade ≥3b postoperative complications., Results: Neoadjuvant chemoradiotherapy was administered to 29 patients (19 (66%) adenocarcinoma and 10 (34%) squamous cell carcinoma). After restaging, nine (31%) patients were excluded (interval metastasis, clinical deterioration, or withdrawn consent). RAMIE was performed in 20 patients (R0-rate 95%). A median of 42 [range 21-71] lymph nodes were resected of which 13 [range 2-35] were cervical. Only 1 (5%) patient had an unexpected contralateral cervical lymph node metastasis. Complications grade ≥3b occurred in 50%. Most frequent complications of any grade were recurrent laryngeal nerve palsy (45%) and pneumonia (40%). Overall survival at 1 year was 85% and quality of life at 6 months was comparable to esophageal cancer patients treated with curative intent., Conclusions: RAMIE with three-field lymphadenectomy following neoadjuvant chemoradiotherapy for patients with resectable esophageal cancer presenting with cervical lymph node metastasis is feasible in a Western population. Because contralateral cervical metastasis is rare, a unilateral neck dissection would suffice in the majority of cases., Clinical Trial: gov Identifier: NCT02426879.

Background: Patients  with esophageal cancer  that invades adjacent structures (cT4b) are precluded from surgery and usually treated with definitive chemoradiotherapy (dCRT). dCRT might result in sufficient downstaging to enable a radical resection, possibly improving survival. This study aimed to assess the perioperative and oncologic outcomes of a salvage robot-assisted minimally invasive esophagectomy (RAMIE) in patients with cT4b esophageal cancer after dCRT., Methods: Between June 2012 and November 2019, patients who underwent a RAMIE with a gastric conduit reconstruction after completion of dCRT for cT4b esophageal carcinoma were identified from a prospectively maintained surgical database at the University Medical Center Utrecht., Results: In total, 24 patients with a histopathologically confirmed T4b adenocarcinoma or squamous cell carcinoma of the esophagus were included. The adjacent organs involved were the tracheobronchial tree (67%), aorta (21%) or both (13%). No conversions or major intraoperative complications were observed. A radical resection was achieved in 22 patients (92%), and a pathologic complete response was observed in 13 (54%) patients. Postoperative grade 2 or higher complications occurred in 20 patients (83%). The disease-free survival at 24 months was 68% for the patients in whom a radical resection was achieved., Conclusion: In patients with cT4b esophageal cancer treated with dCRT followed by a salvage RAMIE, a radical resection rate of 92% was achieved, with acceptable complications and promising survival rates. These results demonstrate the feasibility of a curative surgical treatment for patients with initially irresectable esophageal cancer but underscore the importance of a proper preoperative patient selection.

The role of bedside assistants in robot-assisted minimally invasive esophagectomy is important. It includes knowledge of the procedure, knowledge of the da Vinci Surgical System, skills in laparoscopy, and good communicative skills. An experienced bedside assistant will likely improve efficiency and safety of robot-assisted minimally invasive esophagectomy., (© The Author(s) 2020.
