Objective To investigate the clinicopathological characteristics of proximal gastric cancer (PGC). MethodsThe clinical course and pathologic feature of 118 PGC patients were analyzed, and compared with those of 310 distal gastric cancer (DGC) patients. ResultsThe incidence of PGC was lower than DGC, the percentage of Ⅲ,Ⅳ stages and undifferentiated type in the PGC group were significantly higher than in DGC. For the surgical procedure, patients in the PGC had significantly higher percentages of total gastrectomy and other organ resection than in DGC. The percentage of patients with positive margin and lymph node metastasis in PGC was also significantly higher than in DGC. Esophageal invasion and lymph node metastasis were much more in PGC. The 5year survival of patients with PGC was significantly lower than that with DGC. No significant differences were found between the two groups with respect to the mortality rates and complications. Conclusion The relatively poor prognosis associated with PGC is mainly from advanced cases and esophageal invasion. Early detection and treatment is the most important strategy to improve the survival of patients with PGC.
