BACKGROUND/AIMS: To evaluate tumor invasion (T staging) and lymph node metastasis (N staging) of colorectal cancer preoperatively by using multi-detector computerized tomography (MDCT) and to compare with the histopathological findings.
METHODOLOGY
MDCT scan was performed for 73 patients with pathological proven colorectal carcinoma. One radiologist prospectively evaluated the depth of tumor invasion (T staging) and regional lymph node involvement (N staging). The MDCT assessment was then compared with the histopathological findings for accuracy, sensitivity and specificity.
RESULTS
In this study, the best accuracy results had been acquired for T1 and T2 tumors as 90.4% and 73.9%, respectively. For both histopathologically staged N0 and N1 patients, the accuracy results were 61.6%. The distant metastases were not detected in this study.
CONCLUSIONS
Our study results showed that the MDCT may be useful in the preoperative assessment for the T and N staging in colorectal carcinoma.
背景/目的：通过多排螺旋计算机断层扫描（MDCT）术前评估结直肠癌的肿瘤浸润（T分期）和淋巴结转移（N分期），并与组织病理学结果进行比较。
方法
对73例经病理证实的结直肠癌患者进行MDCT扫描。一名放射科医生前瞻性评估肿瘤浸润深度（T分期）和区域淋巴结受累情况（N分期）。然后将MDCT评估结果与组织病理学结果进行比较，以评估其准确性、敏感性和特异性。
结果
在本研究中，T1和T2肿瘤的最佳准确性结果分别为90.4%和73.9%。对于组织病理学分期为N0和N1的患者，准确性结果均为61.6%。本研究未检测到远处转移。
结论
我们的研究结果表明，MDCT可能有助于结直肠癌术前T和N分期的评估。
