The Relationship Between Ultrasonic Signs Of Primary Lesions Of Gastric Cancer Multiple Factors And Lymph Node Metastases

Objective To study the relation between sonographic characters of lymph node metastases, including image features of gastric carcinoma and those lymph nodes, and pathological findings. Methods To retrospectively analyze sonographices of 155 patients with gastric carcinoma, to study the relation between sonographic characters of lymph node metastasis and pathological findings, including blood supply in primary tumor and its length, TNM classification, Borrmann analysis and tumor localizations. Univariate, Multivariate logistic regression analysis were conducted to determine the value of each sonographic feature. Results According to univariate analysis, the maximum diameter of the primary foci of gastric cancer with lymph node metastasis has significant correlation between (χ~2 =22.977, P<0.01); T stage and lymph node metastasis of gastric cancer with significant correlation between (χ~2 =36.817, P<0.01); Color Doppler flow characteristics of gastric cancer with lymph node metastasis has significant correlation between (χ~2 =13.474, P<0.01); Advanced gastric cancer Borrmann type with lymph node metastasis has statistically significant (χ~2 =6.246, P=0.012); Based on multivariate analysis, the ultrasonographic signs-gastric cancer invasion, maximum diameter, blood type richness and Borrmann type with lymph node metastasis both have significant correlation between. Conclusion①Ultrasonic signs of primary lesions of gastric cancer multiple factors including its length, blood supply in primary tumor, TNM classification and Borrmann classification were correlated with lymph node metastases by Univariate analysis (P<0.05) . The correlation degree from high to low TNM classification>tumor diameter largest>blood supply in primary tumor>Borrmann classification;②The diameter of gastric cancer>5cm,who blood flowⅢ-Ⅱcharacteristics, T3/T4 stage, BorrmannⅢ-Ⅳtype patients corresponding lymph node metastases rate is higher than cancer diameter<5cm, blood flow 0-Ⅰcharacteristics, T1/T2 stage, BorrmannⅠ-Ⅱtype of gastric cancer patients (P<0.05);③For differentiation type of poor gastric cancer that have a strongly ability to attack cancer cells, from purely lesions thickness was not accurate assessment lymph node metastases degree, should combine pathological type comprehensive analysis;④For part of the form irregular, scope of bigger, Especially the growth of around the stomach"C"type of gastric cancer, Ultrasonic very hard to line its biggest diameter, affect lymph node metastasis, should combine other examination evaluation to determine lesions scope;⑤Stomach window Ultrasonic imaging is safety noninvasive, repeatability is strong, through the primary ovens preliminary assessment lymph node metastasis status provide important reference for gastric cancer patients preoperative estimates an illness, and prognosis, choose treatments and operation method, it has important value.
