Abstract: Purpose: To provide more evidences for the diagnosis and the selectionof clinical therapeutic scheme in elderly patients with gastric cancer. Methods: The ultrasonographic diagnosis of 123 gastric cancer in elderly patient swere compared with gastrofiberscope,operation and no-elderly patients of gastriccancer with ultrasonographic diagnosis. Results: There were no significant differences(P>0.05) in diagnosis coincidence rate of elderly gastric cancer among wlfrasonographic(96.7 ％), gastrofiberscope(98.4 ％), pathological nature(100 ％), and no-elderly patients group(94.5 ％). The diagnosis on gastricexter-lumen infiltration and lymphatic metastasis in the patients with gastriccancer of ultrasonographic group was increased significantly as compared with thegastrofiberscope group. There was no significamt difference in ultrasonographic localizationand picture between elderly and no-elderly group. There were not statistically difference in ultrasonographic localizationand operative proof from that in both groups (P>0.05). Conclusions: Ultrasonographic diagnosis was exact to observe the degree ofinfiltration, encroachment of enviroment and lymphatic metastasis with gastriccancer, can evaluate the TNM stage, and is useful for make a therapeutic scheme, bridgea gap from gastrofiberscope.
