背景 直肠癌的初始分期是通过高分辨率磁共振成像 (MRI) 完成的，但也经常使用盆腔计算机断层扫描 (CT)。本研究的目的是评估盆腔 CT 的额外临床益处或它是否可以改变初始分期。 方法 该研究由 187 名直肠癌患者组成。首先，评估除盆腔CT外的影像学检查。其次，根据新发现评估盆腔CT并调整分期。随后，对两个分期结果进行比较，以研究盆腔 CT 的额外临床益处。 结果 与除盆腔CT以外的影像学数据相比，盆腔CT显示的新发现包括盆腔骨转移（n=1）和盆腔腹膜转移（n=3）。然而，新的发现并没有改变主要分期。 3例盆腔腹膜转移患者中，2例经腹部CT已确诊腹膜受累并有腹水，1例发现肝脏及远处淋巴结转移。因此，他们的初始阶段都不需要改变。 结论 将盆腔 CT 添加到治疗前影像策略中并不能为直肠癌的初步评估提供额外的临床益处。
BACKGROUND Initial staging of rectal cancer is done by high-resolution magnetic resonance imaging (MRI), however, pelvic computed tomography (CT) is also frequently used. The aim of this study was to evaluate the added clinical benefit of pelvic CT or whether it can alter the initial staging or not. METHODS The study was composed of 187 patients with rectal cancer. Firstly, imaging except pelvic CT was evaluated. Secondly, the pelvic CT was evaluated and the staging was adjusted according to the new findings. Subsequently, the two staging results were compared to investigate the added clinical benefit of pelvic CT. RESULTS Compared with the imaging data except pelvic CT, new findings revealed by the pelvic CT included metastases of the pelvic bone (n = 1) and pelvic peritoneum (n = 3). However, the new findings did not change the primary staging. Of the three patients with pelvic peritoneal metastasis, two were already determined with peritoneal involvement and ascites by abdominal CT, and the third patient was observed with liver and distant lymph node metastasis. Thus, none of their initial stagings needed to be changed. CONCLUSION The addition of pelvic CT to the pre-treatment imaging strategy cannot provide added clinical benefit for the primary evaluation of rectal cancer.
