【摘要】 目的:观察多层螺旋CT直肠癌影像表现及临床资料,探讨影响直肠癌浆膜面浸润的相关因素方法:64例直肠癌手术患者,男性36例,女性28例,年龄33岁～81岁,平均56.6岁所有患者术前均行16层螺旋CT平扫,观察肿块大小、形态、淋巴结肿大情况;54例行三期动态强化扫描:按照强化程度分型,结合临床资料,分析各因素与直肠癌浆膜面浸润的相关性。结果:全组病例浆膜面浸润率为70%;单因素分析显示,直肠癌癌肿浆膜面的浸润与患者的性别、年龄、肿瘤强化差值、侵犯肠管周径、肿瘤大小、肿瘤大体类型均无相关性(P>0.05);而与肿瘤CT分型、肿瘤分化程度及淋巴结转移有相关性(P<0.05)结论:直肠癌患者癌肿CT、分型、淋巴结转移和肿瘤的分化程度等均可影响肿瘤浆膜面浸润,其中肿瘤分化程度是影响肿瘤浆膜面浸润的最重要因素更多还原

【Abstract】 Objective:To evaluate the factors related to serosa infiltration by rectal carcinomas using 16-channel multi-detector CT.Methods:A total of 64 cases of rectal carcinoma (28 females and 36 males) with an average age of 56.6 years were enrolled in the study.Sixteen-channel multi-detector CT scanning was performed in these 64 patients.Fifty-four cases had enhanced CT.Tumor size,shape,lymphadenectasis, degree of mass enhancement and clinical data were analyzed and compared with pathological results.Results: The rate of local serous infiltration in all patients was 70%.Serosa invasion in rectal cancer cases was not significantly correlated with gender,age,degree of mass enhancement,intestinal circumference invasion, tumor size and differentiation,or tumor type (P>0.05),but it was closely correlated with CT differentiation grouping,lymph node metastasis and degree of differentiation (P<0.05).Conclusion:Degree of differentiation is the most important factor predicting serosa invasion in rectal cancer patients.更多还原
