Objective: The aim of this study was to investigate 3-year survival following a randomized controlled trial comparing minimally invasive with open esophagectomy in patients with esophageal cancer. Background: Research on minimally invasive esophagectomy (MIE) has shown faster postoperative recovery and a marked decrease in pulmonary complications. Debate is ongoing as to whether the procedure is equivalent to open resection regarding oncologic outcomes. The study is a follow-up study of the TIME-trial (traditional invasive vs minimally invasive esophagectomy, a multicenter, randomized trial). Methods: Between June 2009 and March 2011, patients with a resectable intrathoracic esophageal carcinoma, including the gastroesophageal junction tumors (Siewert I), were randomized between open and MI esophagectomy with curative intent. Primary outcome was 3-year disease-free survival. Secondary outcomes include overall survival, lymph node yield, short-term morbidity, mortality, complications, radicality, local recurrence, and metastasis. Analysis was by intention-to-treat. This trial is registered with the Netherlands Trial Register, NTR TC 2452. Both trial protocol and short-term results have been published previously. Results: One hundred fifteen patients were included from 5 European hospitals and randomly assigned to open (n = 56) or MI esophagectomy (n = 59). Combined overall 3-year survival was 40.4% (SD 7.7%) in the open group versus 50.5% (SD 8%) in the minimally invasive group (P = 0.207). The hazard ratio (HR) is 0.883 (0.540 to 1.441) for MIE compared with open surgery. Disease-free 3-year survival was 35.9% (SD 6.8%) in the open versus 40.2% (SD 6.9%) in the MI group [HR 0.691 (0.389 to 1.239). Conclusions: The study presented here depicted no differences in disease-free and overall 3-year survival for open and MI esophagectomy. These results, together with short-term results, further support the use of minimally invasive surgical techniques in the treatment of esophageal cancer.
