【摘要】：目的：探讨MRI对直肠癌术前T、N分期评估的准确性。评估MRI在直肠癌术前T分期、N分期的临床应用价值。方法：选取吉林大学中日联谊医院结直肠肛门外科自2013年1月至2014年11月期间190例术前活检并经组织病理切片证实的直肠癌患者，术前行核磁共振成像（MRI）检查确定肿瘤分期。所有患者检查行MRI检查后平均3.2天（1—6天）,按照TME原则行直肠癌根治手术。手术后的标本依照2013年美国癌症学会(AJCC)结直肠癌分期标准行肿病理学分期。对比直肠癌患者的术前MRI T分期、N分期与术后组织学病理分期的吻合情况。结果：在190例直肠癌患者中，术前MRI T分期与术后病理符合的有151例，准确率为79.5%；与术后病理不符合的有39例，其中过高分期36例，占错误分期比例92.3%；过低分期3例，占比7.7%。N分期，排除术前MRI分期不明确者39例，，术前MRI N分期与术后病理符合的有119例，准确率为78.8%（119/151）。结论： MRI检查对于直肠癌患者术前确定T分期及N分期有较高的准确性。经验丰富的医师阅读MRI有更高的准确性。
[Abstract]:Objective: Objective: to evaluate the accuracy of MRI in preoperative evaluation of rectal cancer. To evaluate the clinical value of MRI in preoperative T staging and N staging of rectal cancer. Methods: From January 2013 to November 2014, 190 patients with rectal cancer confirmed by biopsy and histopathological section were selected from the Hospital of Sino-Japanese Friendship Hospital of Jilin University from January 2013 to November 2014. MRI was performed before operation to determine the staging of the tumor. All patients underwent MRI for an average of 3. 2 days and 1-6 days). Radical resection of rectal cancer in accordance with TME's principles. Specimens after operation were performed in accordance with the American Cancer Society (AJCC) in 2013. The preoperative MRI T staging of colorectal cancer patients was compared. The anastomosis between N staging and histological staging was observed. Results: Among the 190 patients with rectal cancer, the preoperative MRI T staging was consistent with postoperative pathology in 151 cases, and the accuracy rate was 79.5%. 39 cases were not in accordance with postoperative pathology, including 36 cases with excessive staging, accounting for 92.3% of the wrong staging; There were 3 cases with low staging (7.7%), 39 cases were excluded from preoperative MRI staging, and 119 cases with preoperative MRI N staging were consistent with postoperative pathology. The accuracy rate is 78. 8%. Conclusion: MRI has a higher accuracy in determining preoperative T and N staging in rectal cancer patients. Experienced physicians have higher accuracy in reading MRI.
