title: [Clinical study on post-operative metastasis prevention of progressive stage of gastric cancer by weichang'an].
abstract: OBJECTIVE
  To observe the effect of Weichang'an (WCA, a Chinese preparation) in preventing post-operative metastasis of progressive stage of gastric cancer.
  
  
  METHODS
  A prospective randomized, controlled study was conducted by dividing the 148 patients of progressive staged gastric cancer after radical operation into the WCA group, the chemotherapy (CT) group and the WCA + CT group, to observe the survival rate, metastasis rate, quality of life (QOF) and tumor-bearing survival time after relapse (TST) in patients.
  
  
  RESULTS
  The 1-, 2- and 3-year survival rate after operation in the WCA + CT group was 89.51%, 69.77% and 55.76% respectively, which was significantly higher than that in the CT group (83.86%, 59.33% and 49.43%) respectively (P < 0.05), but showed insignificant difference as compared with that in the WCA group (93.23%, 79.34% and 71.78%). Only 1-year metastasis in the WCA group was 15.25%, and in the WCA + CT group was 15.52%, the two were significantly lower than that in the CT group (35.48%, P < 0.05). But the comparison of 2-year metastasis rate among the 3 groups (28.81%, 41.38% and 45.16%) and 3-year metastasis rate among them (33.90%, 46.55% and 51.61%) were insignificantly different. The QOF and TST were markedly better in the WCA group than those in the CT group.
  
  
  CONCLUSIONS
  WCA has preventive effect on relapse and metastasis in post-operational gastric cancer patients.
