Predicting Early Cancer-related Deaths after Curative Esophagectomy for Esophageal Cancer
Esophagectomy is the primary treatment for esophageal cancers, but a few patients still suffer from early recurrence and die within one year after surgery. The aim of this study was to identify preoperative predictive risk factors for early cancer-related deaths after curative esophagectomy for esophageal squamous cell carcinoma. The records of 200 consecutive patients with esophageal cancer who underwent esophagectomy between 1990 and 2009 were retrospectively reviewed. The preoperative clinical characteristics of the remaining 32 patients who died of cancer within one year were compared with those of 168 patients who survived for more than one year postsurgery. The most frequent cause of death was lymph node recurrence followed by local recurrence and lung metastases. A tumor size 60 mm or greater and lymph node metastases in two fields on preoperative imaging were identified as prognostic factors on multivariate analysis. The one-year survival rate and median survival time of patients with both these risk factors were 40 per cent and 12 months, respectively. Aggressive additional treatment may be needed if both a tumor size 60 mm or greater and lymph node metastases in two fields are found during diagnostic imaging before esophagectomy for esophageal squamous cell carcinoma.
