【摘要】：目的评估直肠腔内超声(ERUS)、MRI对直肠癌患者术前分期与病理对照的准确率。方法回顾性分析2015年1月至12月于本院行ERUS检查和盆腔MRI检查的72例直肠癌患者资料,根据术后病理结果,按照美国癌症联合委员会(AJCC)直肠癌分期指南行T、N分期,将ERUS和MRI对直肠癌局部T、N分期的准确率与病理结果对照,并行一致性评价。结果总共纳入72例直肠癌患者,与术后病理结果对照,经ERUS、MRI的T分期总准确率分别为81.94%(59/72)、66.67%(48/72)(Kappa值分别为0.745、0.524,P均0.001),经ERUS、MRI的N分期总准确率分别为65.28%(47/72)、77.78%(56/72)(Kappa值分别为0.350、0.599,P均0.001)。结论与病理结果对照,ERUS对直肠癌术前T分期的一致性较好,而MRI对N分期的一致性较好,ERUS与MRI是评估直肠癌术前分期有效的影像学检查方法。
[Abstract]:Objective to evaluate the accuracy of intrarectal ultrasound Mr imaging for preoperative staging and pathology of rectal cancer. Methods 72 patients with rectal cancer who underwent ERUS and pelvic MRI from January 2015 to December were retrospectively analyzed. According to the postoperative pathological results and according to the AJCC rectal cancer staging guidelines, the accuracy of ERUS and MRI in the local staging of rectal cancer was compared with the pathological results. Results A total of 72 patients with rectal cancer were included and compared with postoperative pathological findings. The total accuracy of T staging by ERUST MRI was 81.94 / 59 / 72 / 66.67 and the Kappa value of 48 / 72 / 66.67 was 0.7450.24 / 0.24, respectively. The total accuracy of N staging of ERUST MRI was 65.28 / 77.78 / 56 / 77.78 / 56 / 77.78 / 77.78 / 77.78, respectively (P 0.001). Conclusion compared with the pathological results, ERUS has better consistency in preoperative T staging of rectal cancer. MRI is more consistent with N staging. ERUS and MRI are effective imaging methods to evaluate preoperative staging of rectal cancer.
