摘要
目的总结胃粘液腺癌多层螺旋CT特征,以提高胃粘液腺癌影像学诊断的准确率。方法回顾性分析101例经临床病理证实的胃癌临床及影像学资料,其中胃粘液腺癌26例,非粘液腺癌75例,总结胃粘液腺癌多层螺旋CT及临床特征并与非粘液腺癌相对比。结果 26例胃粘液腺癌患者中,男23例,女3例,平均发病年龄为(65.1±3.4)岁,好发部位为胃窦部;与非粘液腺癌相比,两组病灶在好发年龄、发病部位及性别比方面无统计学差异(P>0.05);胃粘液腺癌粘膜完整率为92.3%(24/26),分层强化率为80.8%(21/26),延迟强化率92.3%(24/26),两组病灶在分层强化、强化方式及胃粘膜完整程度上有差异(P<0.05)。结论胃粘液腺癌影像学表现有一定特征性,当胃窦部肿块呈现分层、延迟强化,而胃粘膜又相对完整时,常提示胃粘液腺癌诊断。
Objective To sum up the MSCT （Multi-Slice CT） signs of gastric mucinous adenocarcinomain order to improve the accuracy of diagnosis. Methods The MSCT signs and clinical data of 101clinically-and-pathologically-confirmed stomach cancers were retrospectively analyzed, including 26cases of gastric mucinous adenocarcinoma and 75 cases of non-MUC （Non-Mucinous Adenocarcinoma）.The MSCT signs and clinical data of gastric mucinous adenocarcinoma were summarized and comparedwith non-MUC. Results In the 26 gastric mucinous adenocarcinoma patients, 23 cases were male and3 cases were female; the patients’ mean age was （65.1±3.4） years old; the predilection site was gastricantrum. There was no statistically significant difference between the age, predilection site and sex ratio oftwo groups （P〈0.05）. The gastric mucosa integrity rate was 92.3% （24/26）; the layered enhancement ratewas 80.8% （21/26）; the delayed reinforcement rate was 92.3% （24/26）. There were significant differencesbetween the gastric mucosa integrity, the layered enhancement and delayed reinforcement of both groups（P〈0.05）. Conclusion The gastric mucinous adenocarcinoma had certain imaging characteristics. Whenthe MSCT signs of gastric antrum were layered and delayed enhancement with the integrity of gastricmucosa, it usually indicated gastric mucinous adenocarcinoma.
