Abstract:
Objective To discuss the spiral CT features of lymph node metastasis in advanced gastric cancer, and to investigate the correlation between spiral CT features and pathologic results. Methods Spiral CT scan and triphasic enhancement spiral CT scan were performed in 59 patients with advanced gastric cancer before operation. Results ①The pathologic metastatic rate of lymph node in gastric cancer was high when the lymph nodes were nubby-mixed, prominently enhanced, unsymmetrical enhanced and ≥9 mm in diameter on spiral CT (P<0.05). ②The detection rate of lymph node metastasis with spiral CT was high when carcinoma tissues were poorly differentiated, Borrmann Ⅲ+Ⅳ, T3-4 staging and TNM Ⅲ+Ⅳ staging. Conclusion The spiral CT features of lymph node (distributing type, size, enhanced degree, enhanced mode and staging) can reflect the pathologic characteristics of lymph node metastasis in gastric carcinoma. Pathologic characteristic of gastric tumor determines the detection rate of lymph node metastasis on spiral CT. The accuracy of CT to diagnose lymph nodes metastasis will be improved by integrating the spiral CT features of both gastric tumor and lymph node.
