title: [Study on relationship between Deficiency Syndrome of TCM and the biological behavior in patients of esophageal carcinoma].
abstract: OBJECTIVE
  To investigate the relation between Deficiency Syndrome (DS) of TCM and the invading depth, lymphnode metastasis, TNM stage and prognosis prediction of esophageal carcinoma.
  
  
  METHODS
  According to Syndrome Differentiation of TCM, 101 patients of esophageal carcinoma were evaluated before operation and divided into two groups, the DS group and the non-DS group.
  
  
  RESULTS
  Thirty-eight cases in the 101 patients were DS, among them, 14 were Qi-Deficiency, 10 Yin-Deficiency, 10 Qi-Yin Deficiency, 2 Qi- and blood Deficiency, 1 Yang-Deficiency and 1 Yin-Yang Deficiency. There were significant differences between the DS group and non-DS group in the invading depth (deeper in DS), metastasis of lymphnode (severer in DS) and TNM stage (later in DS) of esphageal carcinoma, (P < 0.05).
  
  
  CONCLUSIONS
  There is a significant relation between DS and the biological behavior of esophageal carcinoma. The prognosis of DS patients is poorer than that of the non-DS patients.
