The authors report the recurrence pattern of esophageal cancer after thoracoscopic-assisted esophagectomy (TAE), comparing it to the recurrence pattern after open surgery and identify prognostic factors for recurrence. To improve long-term survival for esophageal cancer radical surgery has been proposed increasingly, however, recurrent disease remains a problem. Opinion is divided as to the adequacy of resection possible using minimally invasive techniques with concerns that there may be an increased incidence in locoregional recurrence. A total of 221 patients who underwent esophagectomy at the Princess Alexandra Hospital without any neoadjuvant or adjuvant therapy were identified from a prospective database. Patients were followed up for the detection of symptomatic recurrence for a median of 59 months. Within this group 165 patients underwent TAE and 56 an open transthoracic esophagectomy (TTE). The 5-year overall recurrence rate was 133/221 (60%). The 5-year rates of symptomatic first recurrence following TAE was 4%, 9%, and 47% for local, regional, and distant recurrence, respectively. The 5-year rates of symptomatic first recurrence following TTE was 5%, 18%, and 55% for local, regional, and distant recurrence, respectively. Operative approach was not a prognostic factor for any type of recurrence. Independent prognostic factors associated with locoregional recurrence were positive margins and number of positive nodes. Distant recurrence was associated with T stage, differentiation, tumor length >6 cm, and number of positive nodes. Distant recurrence remains a significant problem in esophageal cancer. TAE achieved adequate locoregional control and compared favorably with open TTE.
