Background
Extended radical esophagectomy with three-field lymph node dissection (3-FLD) has offered significant survival benefit, but some patients still suffer from early recurrence and die within 1 year after surgery. The purpose of this study was to identify the risk factors that influence early death due to cancer recurrence after extended radical esophagectomy with 3-FLD.
Methods
A consecutive series of 276 patients who underwent extended radical esophagectomy with 3-FLD was retrospectively reviewed. Excluding patients who underwent incomplete resection or died of other diseases within 1 year, we compared the clinicopathological characteristics between 203 patients who survived more than 1 year (1-year survival group) and 27 who died of cancer recurrence within 1 year (early-death group) by univariate and multivariate analysis.
Results
Sixty-six patients (32.5%) had recurrent disease in the 1-year survival group. Hematogenous recurrences were more frequent in the early-death group than in the 1-year survival group (41% vs. 26%, respectively, p = 0.0481). There was a significant difference in nodal status, number of metastatic nodes, pathological stage, vessel invasion, and intramural metastasis, and there was borderline significance in the difference of depth of invasion and histological type between the two groups by univariate analysis. Multivariate analysis demonstrated that intramural metastasis was an independent risk factor.
Conclusions
Patients with intramural metastasis have a significant risk of early death even after extended radical esophagectomy with 3-FLD; however, it remains unknown whether surgical intervention can play a significant role for these patients.
