Abstract:
Objectives: The research is designed to study the accuracy and characteristics of diagnostic methods for estimating the expansive type of gastric cancer in normal clinical practice, and to evaluate the clinical significance of this estimation. Methods: Preoperative Borrmann classifications of gastric cancer were diagnosed by endoscopies, barium studies and computed tomographies. The results were compared with Borrmann classifications from surgical specimens. Results:The diagnostic accuracy of endoscopy in small gastric cancers was better than that in large gastric cancers. The diagnostic accuracy of CT for type Ⅰ and Ⅳ, which have more obvious gross characteristics, was better, and for type Ⅱ and type Ⅲ, which need to be differentiated by local characteristics such as morphologic appearances of ulcers, was worse. The barium study estimated the expansive type of gastric cancer according to borders of tumors, characteristics of ulcers and whole figure, However, it was difficult to observe detailed changes. Conclusions: To improve the veracity of preoperative diagnosis for the expansive type of gastric cancer requires integrative use of endoscopies, barium studies and computed tomographies. The diagnosis of biological characteristics of gastric cancer reflects its quality, and the diagnosis of aggressive degree reflects its quantity. Only with the diagnosis of these two aspects, can we estimate the clinical pathological process of the gastric cancer completely and comprehensively, so as to select the most reasonable and desirable treatment.
