ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical characteristics and prognostic factors of esophageal carcinosarcoma.</p><p><b>METHODS</b>The clinical data of patients treated by surgery and pathologically diagnosed as esophageal carcinosarcoma between January 1967 and December 2008 were retrospectively reviewed. There were 28 male and 4 female patients aged from 39 to 76 years with a median age of 58 years. All the data were analyzed using SPSS 15.0 software. The overall survival rates were calculated and compared with the Kaplan-Meier method and the Log-rank test. The prognostic factors were identified by Cox hazard regression model.</p><p><b>RESULTS</b>Among all the 32 patients included, 29 patients were polypoid type, 2 patients were fungoid type and 1 patient were medullary type. With regard to the depth of tumor infiltration, 17 patients involved the mucosa or submucosa (pT1), 13 patients involved the muscularis propria (pT2), 2 patients involved the adventitia (pT3). The involvement of local lymph nodes was present in 10 patients, with an incidence of 31.3%, including metastatic carcinoma alone in 7 patients and both carcinomatous and sarcomatous components in 3 patients. According to the most recently published international TNM staging system for esophageal carcinoma (AJCC 2009), 15 patients were in stage I, 13 patients in stage II, 4 patients in stage III. The 1-, 3- and 5-year overall survival rates of the whole group were 90.0%, 72.1% and 57.0%, respectively. Both in single-factor prognostic analysis and in Cox multivariate analysis, pathological N stage was the only prognostic factor (RR = 2.531, 95%CI: 1.055 - 6.070).</p><p><b>CONCLUSIONS</b>Esophageal carcinosarcoma is consisted of both sarcomatous component and carcinomatous component, while the latter one appears more frequently in local lymph node metastasis. In multivariate prognostic analysis, pathological N stage is the only independent prognostic factor. Curative resection of this tumor may achieve good prognosis because of its' lower incidence of lymph node metastasis and less invasive tendency.</p>
