Background and objectives: Minimally invasive esophagectomy is emerging with comparable short-term outcomes as open esophagectomies. Neoadjuvant chemoradiotherapy followed by surgery is considered standard of care in the Netherlands for patients with esophageal cancer. The aim of this study was to analyze the long-term oncologic outcome after neoadjuvant chemoradiotherapy followed by totally minimally invasive esophagectomy.
Methods: Neoadjuvant carboplatin and paclitaxel based chemotherapy was concomitantly given with 41.4 Gy radiotherapy. Six weeks after neoadjuvant treatment, totally minimally invasive esophagectomy was performed.
Results: From December 2010 until December 2015 161 patients received this combination of treatment. In 128 male and 33 female patients with median age of 65 years (58-71), 88 minimally invasive esophagectomies with intrathoracic anastomosis and 73 minimally invasive esophagectomies with cervical anastomosis were carried out. Radical (R0) resection was confirmed in 156 patients (97%). In hospital mortality occurred in 6 patients (3.7%). Overall survival was 79% and 51% at 1 and 5 years, respectively, with a median follow-up of 24.5 months (13-38). Disease-free survival was, respectively, 76% and 55%.
Conclusions: Totally minimally invasive esophagectomy after neoadjuvant chemoradiotherapy for esophageal cancer is a safe treatment with low postoperative mortality rates and favorable overall and disease-free survival.
