Objective To study the pathological characters and prognosis of 33 cases of gastric signet ring cell carcinoma.Methods The difference of clinicopathology and survival between signet ring cell carcinoma and non-signet ring cell carcinoma in 166 gastric cancer patients were analyzed restropectively.Results Thirty-three gastric signet ring cell carcinoma was observed in 166 gastric cancer samples(19.88%) and had no relationship with general pathological characters such as sex,lesion location,differentiation,depth of infiltration,lymph node metastasis,distant metastasis and clinical stage(P0.05).Gastric signet ring cell carcinoma patients were younger(age60,P=0.032) and had higher ratio of neural invasion(P=0.021) than those of non-signet ring cell carcinoma patients.The gastric signet ring cell carcinoma patients had poorer 4 years survival rate(42.4%) than that of non-signet ring cell carcinoma patients(66.2%),showing significant differences(P0.05).Conclusion The gastric signet ring cell carcinoma has a worse prognosis compared to non-signet ring cell carcinoma.
