Prognostic analysis of the patients with stage-III esophageal squamous cell carcinoma after radical esophagectomy.
OBJECTIVE
Most patients with esophageal carcinoma have disease in the locally late stage (stage III) when first diagnosed, with surgery as the first treatment of choice. This study analyzed the clinical data of patients with esophageal squamous carcinoma after radical esophagectomy and investigated prognostic factors.


METHODS
The data of 361 patients with esophageal squamous carcinoma who underwent radical esophagectomy and were hospitalized at Sun Yat-sen University Cancer Center between January 1997 and March 2004 were analyzed. The Kaplan-Meier method was used to analyze prognosis, log-rank test was used to compare the groups, and the Cox proportional hazards model was used for multivariate analysis.


RESULTS
The 1-, 2-, 3-, 4-, and 5-year survival rates were 67.7%, 40.6%, 27.5%, 23.4%, and 20.1%, respectively. Based on univariate analysis, the degree of invasion, rate of lymph node metastasis, number of metastatic regions, number of metastatic lymph nodes, postoperative complications, and duration of surgery were prognostic factors. Based on multivariate analysis, the degree of invasion, rate of lymph node metastasis, and postoperative complications were independent factors for the prognosis.


CONCLUSIONS
Of all clinical and pathologic factors, the degree of invasion, rate of lymph node metastasis, and postoperative complications were independent prognostic factors for the patients with stage-III esophageal squamous carcinoma after radical esophagectomy.
