Approximately 10-20 % of esophageal cancer patients in whom recurrence is diagnosed experience late recurrence beyond 2 years after esophagectomy. However, the risk of late recurrence is still unclear. The aim of this study was to identify the risk factors of late recurrence for appropriate postoperative surveillance. A total of 447 patients underwent radical esophagectomy and reconstruction for esophageal cancer from 2005 to 2014. Patients who had recurrence beyond 2 years after esophagectomy were defined as the late recurrence group and the remaining patients with recurrence as the early recurrence group. A comparison of the clinicopathological factors and prognosis was performed between patients with early recurrence, late recurrence, and no recurrence. Recurrences were recognized in 117(26.2 %) of the 447 patients. Recurrence was diagnosed within 2 years after surgery in 103 patients (88.0 %) and after 2 years in 14 patients (12.0 %). Patients with late recurrence showed a favorable prognosis compared with those with early recurrence (P = 0.0131), and late recurrence was an independent factor associated with a favorable prognosis after recurrence (HR 0.199, P = 0.025). In the comparison between patients with late recurrence and those with no recurrence who had a minimal recurrence-free survival of 2 years, pathological lymph node metastasis at esophagectomy was found to be an independent predictor of late recurrence (HR 7.296, P = 0.043). Pathological lymph node metastasis at esophagectomy is a risk factor of late recurrence for esophageal cancer, and a close, lifelong follow-up is recommended for such patients.
