Prognosis of Chinese Criteria grouping in all thoracic ESCC patients, upper and lower mediastinal ESCC patients. (A) The OS rate in the thoracic ESCC patients in the mediastinal metastasis group was significantly lower than that in the local metastasis group (P<0.001). The OS rate of patients in local metastasis group was significantly lower than that in the skip metastasis group (P=0.013). The survival difference between the skip and no metastasis groups was significant (P<0.001). (B) In upper mediastinum, OS rate in the mediastinal metastasis group was significantly lower than in the local metastasis group (P=0.002). The OS rate in the local metastasis group tended to be lower than that in the skip metastasis group, the difference was not significant (P=0.382). There was a significant difference in OS rate between the skip and the no metastasis groups (P<0.001). (C) In lower mediastinum, the OS rate in the local metastasis group was significantly lower than in the skip metastasis group (P=0.010). ESCC, esophageal squamous cell carcinoma; OS, overall survival.
