The Analysis of the Prognosis of Proximate Gastric Cancer

Objective: To study the relation between the number of metastatic lymph node and the prognosis of proximate gastric cancer. Methods: 32 patients with gastric cancer underwent D 2 or D 3 operation, and lymph nodes were harvested from specimen. The number of lymph nodes of proximate gastrectomy were compared with that of total gastrectomy and was the prognosis evaluated according to the 1997 5th TNM stage system. Results: There were 2015 lymph node obtained from the 32 specimens, the mean was 63 lymph nodes per case. There were 57 lymph nodes per case for patients with proximate gastrectomy and 70 per case with total gastrectomy. According to the new 5th N stage system, the 5 year survival of N 1, N 2, N 3 were 36.46%, 11.05%, and 0% respectively. Conclusion: With the carcinoma invading widely, wide resection with extended lymph node dissection has been proved availability. The new quantitative N staging system is superior to the old one.
