【摘要】：目的： 探討MRI對(duì)直腸癌術(shù)前T、N分期評(píng)估的準(zhǔn)確性。 評(píng)估MRI在直腸癌術(shù)前T分期、N分期的臨床應(yīng)用價(jià)值。 方法： 選取吉林大學(xué)中日聯(lián)誼醫(yī)院結(jié)直腸肛門外科自2013年1月至2014年11月期間190例術(shù)前活檢并經(jīng)組織病理切片證實(shí)的直腸癌患者，術(shù)前行核磁共振成像（MRI）檢查確定腫瘤分期。所有患者檢查行MRI檢查后平均3.2天（1—6天）,按照TME原則行直腸癌根治手術(shù)。手術(shù)后的標(biāo)本依照2013年美國(guó)癌癥學(xué)會(huì)(AJCC)結(jié)直腸癌分期標(biāo)準(zhǔn)行腫病理學(xué)分期。對(duì)比直腸癌患者的術(shù)前MRI T分期、N分期與術(shù)后組織學(xué)病理分期的吻合情況。 結(jié)果： 在190例直腸癌患者中，術(shù)前MRI T分期與術(shù)后病理符合的有151例，準(zhǔn)確率為79.5%；與術(shù)后病理不符合的有39例，其中過高分期36例，占錯(cuò)誤分期比例92.3%；過低分期3例，占比7.7%。N分期，排除術(shù)前MRI分期不明確者39例，，術(shù)前MRI N分期與術(shù)后病理符合的有119例，準(zhǔn)確率為78.8%（119/151）。 結(jié)論： MRI檢查對(duì)于直腸癌患者術(shù)前確定T分期及N分期有較高的準(zhǔn)確性。經(jīng)驗(yàn)豐富的醫(yī)師閱讀MRI有更高的準(zhǔn)確性。
[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.
