【摘要】：目的:評估直腸腔內(nèi)超聲(Endorectal Ultrasound,ERUS)、磁共振(Magnetic resonance imaging MRI)對直腸癌患者術前分期與病檢對照的準確性。方法:回顧性分析2015年1月至2015年12就診于我院行經(jīng)直腸腔內(nèi)超聲檢查和盆腔磁共振檢查的72例直腸癌患者,根據(jù)術后病檢結果,按照美國癌癥聯(lián)合委員會(American Joint Committee On Cancer,AJCC)直腸癌分期指南行T、N分期,將直腸腔內(nèi)超聲和磁共振對直腸癌局部T、N分期的準確性與病檢結果對照,并行一致性評價。結果:總共納入72例直腸癌患者,與術后病檢結果對照,經(jīng)直腸腔內(nèi)超聲、磁共振的T分期總準確率分別為81.94%(59/72)、66.67%(48/72)(Kappa值分別為0.745,0.524,P均0.001),經(jīng)直腸腔內(nèi)超聲、磁共振的N分期總準確率分別為65.28%(47/72)、77.78%(56/72)(Kappa值分別為0.350、0.599,P均0.001);結論:與病檢結果對照,直腸腔內(nèi)超聲對直腸癌術前T分期的一致性較好,而磁共振對N分期的一致性較好,直腸腔內(nèi)超聲與磁共振是評估直腸癌術前分期有效的影像學檢查方法。
[Abstract]:Objective: To evaluate the transrectal ultrasound (Endorectal Ultrasound, ERUS), magnetic resonance (Magnetic resonance imaging MRI) on the accuracy of preoperative staging and pathological examination. Methods: a retrospective analysis from January 2015 to 2015 12 patients in our hospital underwent transrectal ultrasonography and Pelvic MRI of 72 cases of colorectal cancer patients. According to the postoperative pathological results, according to the American Joint Committee on cancer (American Joint Committee On Cancer, AJCC) for T staging, N staging, the transrectal ultrasound and magnetic resonance imaging of rectal cancer Department of the Ministry of T, N and pathological results of the control accuracy of staging, parallel consistency evaluation. Results: a total of 72 cases were included in patients with rectal cancer, compared with pathological results after surgery, transrectal ultrasound, magnetic resonance imaging and the total accuracy of T was 81.94% (59/72), 66.67% (48/72) (Kappa = 0.745,0.524, P < 0.001), the Transrectal ultrasound, magnetic resonance imaging and the total accuracy of N was 65.28% (47/72), 77.78% (56/72) (Kappa = 0.350,0.599, P < 0.001); conclusion: compared with pathological results, transrectal ultrasonography in the preoperative staging of rectal cancer T consistency is good, and the magnetic resonance of N staging is better, transrectal ultrasonography and magnetic resonance imaging is to assess the preoperative staging of rectal cancer effective imaging method.
