背景：根据组织病理学，结直肠腺癌是最常见的结直肠癌类型之一，约占全世界每年诊断的癌症病例的10%。肿瘤的大小和癌胚抗原（CEA）的水平被用来确定结直肠癌的存在及对其进行评价。然而，在印度尼西亚人口中，基于腹部CT增强扫描的结直肠癌大小与CEA水平之间的相关性研究仍然非常少。本研究旨在分析IV期结直肠腺癌患者腹部CT增强扫描检查的肿瘤大小与癌胚抗原（CEA）水平之间的关系。受试者和方法：2021年2月至2021年7月，在苏拉卡尔塔Moewardi博士医院放射科进行了一项横断面研究。本研究共选取了40名IV期结直肠腺癌患者。患者已经有了血液CEA水平的检查结果，并进行了腹部CT增强扫描。因变量是血液CEA水平。自变量是肿瘤大小。数据从医疗记录中收集，并通过Spearman检验进行分析。结果：肿瘤大小和CEA水平之间存在着积极和显著的关系（r=0.47；p=0.003）。结论：肿瘤大小与IV期结直肠腺癌患者的血液CEA水平呈正相关。
