Pathology and prognosis of gastric cancer (1), histological type and differentiation
Histological types of gastric cancer reflect the different biological characteristics and prognosis of patients, such as papillary carcinoma 5-year survival was 32.9%, 25.4% tubular adenocarcinoma, undifferentiated carcinoma was 20.5%, poorly differentiated adenocarcinoma 19.9 %, prime adenocarcinoma accounted for 19.3% solution.
Gastric cancer pathology and prognosis (2) depth of invasion of gastric cancer cells
100% 5-year survival rate of carcinoma in situ, invasion to the stalk membrane under the 5-year survival 90%, 70% of violations of muscle layer, serosal invasion were 20%, serous violation of the organizers of adjacent organs outside the 5-year survival is only about 5%.
Pathology and prognosis of gastric cancer (3) lymph node metastasis
Lymph node metastasis, 5-year survival rate of only 7.6%, no lymph node metastasis was 41.8%. Another set of data without lymph node metastasis reported 5-year survival rate with lymph node metastasis than 2 times
