Is tumor length a prognostic indicator for esophageal squamous cell carcinoma? A single larger study among Chinese patients



Is tumor length a prognostic indicator for esophageal squamous cell carcinoma? A single larger study among Chinese patients



International Journal of Clinical and Experimental Pathology 8(5): 5008-5016



In esophageal cancer, depth of wall penetration, reflected by T classification, represents the most important prognostic variable. Our study aimed to investigate the impact of tumor length, measured as the longitudinal length, on the outcome of esophageal squamous cell carcinoma (ESCC) patients. The survival data of 362 ESCC patients who underwent surgical resection as the primary treatment between 1999 and 2007 were collected retrospectively. Receiver-operator characteristic analysis was applied to identify the optimal cut-off values. 4.0 cm was identified as the optimal cut-off value within the whole group. Tumor length greater than 4.0 cm was associated with increasing T stage (P=0.001), N stage (P=0.046), and tumor differentiation (P=0.033). Univariate analysis and multivariate analysis both found that tumor length greater than 4.0 cm was associated with worse overall survival compared with shorter tumors (P<0.001). It appeared to have a greater impact on N0-N1 (P<0.001, P=0.026, respectively) than N2-N3 and appeared to have a higher impact on the lower-stage patients than the higher-stage patients. Tumor length proved to be an independent prognostic parameter for ESCC patients, especially for node-negative and lower-stage patients. More attention should be paid to its role in the management of ESCC.
