不同血行途径肝转移瘤CT征象的logistic回归分析研究

Different Blood Line Way to Spread to the Liver Tumor CT Signs of Logistic Regression analysis

目的探讨不同血行途径肝转移瘤的CT征象和鉴别诊断。方法回顾性分析本院2013年6月至2014年3月期间收治及经病理组织学确诊的66例肝转移瘤患者的CT和临床资料。其中肝动脉来源27例,门静脉来源39例;男40例,女26例;年龄40~80岁。对两组不同来源肝转移瘤的CT特征进行了单因素及多因素logistic回归分析。结果两组不同来源肝转移瘤在钙化征象上的差异有统计学意义（P〈0.05）,两组肝转移瘤的血供特点差异无统计学意义（P〉0.05）。结论钙化常见于门静脉来源的肝转移瘤,此征象对确定原发瘤的来源有一定的引导作用;肝转移瘤供血方式及血供丰富与否与转移瘤的血行途径无显著相关性。肿瘤供血方式与原发瘤的生物学特性相关。

Objective To explore different blood line way CT sign of liver metastases and differential diagnosis. Methods The histologic diagnosis of 66 cases of patients with liver metastases of CT and clinical data from June 2013 to March 2014 in our hospital were retrospectively analyzed. Of the 27 cases of hepatic artery origin,portal vein sources of 39 cases; Men 40 patients,26 cases of women,aged 40 to 80 years old,on two groups of different source CT features of hepatic metastases has carried on the single factor and multi-factor logistic regression analysis. Results Two groups of different sources of liver metastases in calcification signs on the difference was statistically significant（ P〈0. 05）,two groups of characteristics of its blood supply from the hepatic metastases no statistical difference（ P〉0. 05）. Conclusion Calcium found in liver metastases source of portal vein,the signs of the source of the primary tumor has a certain guiding role; Metastases to the liver blood flow and blood supply is rich or not and metastatic tumor blood line way had no significant correlation. Tumors associated with the biological characteristics of primary tumor blood supply.
