Abstract:
Objective: To study the clinicopathlogic factors and survival in elderly patients with early gastric cancer(EGC).
Methods: The relationship between lymph node metastasis and clinicopathologic factors were analysed in 52cases EGC.
Results: EGC was no symptom in 57.7% elderly patients,Gross typeⅡc had a high incidence,Multiple EGC were found in 9.6% patients,The mumber of well or moderately differentiated adenocarcinoma was higher than that poorly differentiated adenocarcinoma in EGC,The lymph node metastasis was found in 15% petients in submucosal cancer,but no lymph node metastasis in the mucosal cancer.Ricurrence was seen in five patients,the incidence of ricurrence was significantly higher in submucosal,poorly differentiated adenocarcinoma.5year survival rate was 98.1%,10year survival rate was 96.1%,15year survival rate was 92.3%,20 year survival rate was 90.3%.Endoscopic mucosal resection is recommended for mucosal cancer in elderly patients.
Conclusion: The presence of lymph node metastasis and invasion of submucosal layer and poorly differentiated carcinoma are critical factors in the prognosis of gastric cancer.
