To explore the distribution of lymph node metastases, to analyze the cliniopathologic factors of thoracic esophageal carcinoma after curative resection, and to provide the criteria of irradiated region delineation in radiotherapy for esophageal carcinoma. The clinicopathological data of 763 patients who underwent esophagecotomy from Jun 2002 to Jun 2006 were retrospectively analyzed. The regularity of lymph node metastases of thoracic esophageal cancer and clinicopathological factors were stratified and analyzed with SPSS13.0 software. Of the 763 patients, a total of 5846 lymph nodes were dissected with an average of 7.7 lymph nodes in each case. Metastatic lymph nodes were 711, the ratio of metastatic lymph node was 12.2%, and 297 patients had lymph node involved, the lymph node metastasis rate was 38.9%. The metastatic lymph nodes of upper-thoracic esophagus were mainly observed in the supraclavicular and paratracheal regions (P < 0.05), the metastatic lymph nodes of middle-third thoracic esophagus were bid
