| 2 | Accuracy of computed tomography in nodal staging of colon cancer patients显示文摘AIM: To predict node-positive disease in colon cancer using computed tomography(CT).METHODS: American Joint Committee on Cancer stage Ⅰ-Ⅲ colon cancer patients who underwent curavtiveintent colectomy between 2007-2010 were identified at a single comprehensive cancer center. All patients had preoperative CT scans with original radiology reports from referring institutions. CT images underwent blinded secondary review by a surgeon and a dedicated abdominal radiologist at our institution to identify pericolonic lymph nodes(LNs). Comparison of outside CT reports to our independent imaging review was performed in order to highlight differences in detection in actual clinical practice. CT reviews were compared with final pathology. Results of the outside radiologist review, secondary radiologist review, and surgeon review were compared with the final pathologic exam to determine sensitivity, specificity, positive and negative predictive values, false positive and negative rates, and accuracy of each review. Exclusion criteria included evidenceof metastatic disease on CT, rectal or appendiceal involvement, or absence of accompanying imaging from referring institutions.RESULTS: From 2007 to 2010, 64 stageⅠ-Ⅲ colon cancer patients met the eligibility criteria of our study. The mean age of the cohort was 68 years, and 26(41%) patients were male and 38(59%) patients were female. On final pathology, 26 of 64(40.6%) patients had nodepositive(LN+) disease and 38 of 64(59.4%) patients had node-negative(LN-) disease. Outside radiologic review demonstrated sensitivity of 54%(14 of 26 patients) and specificity of 66%(25 of 38 patients) in predicting LN+ disease, whereas secondary radiologist review demonstrated 88%(23 of 26) sensitivity and 58%(22 of 38) specificity. On surgeon review, sensitivity was 69%(18 of 26) with 66% specificity(25 of 38). Secondary radiology review demonstrated the highest accuracy(70%) and the lowest false negative rate(12%), compared to the surgeon review at 67% accuracy and 31% false negative rate and the outside radiology review at 61% accuracy and 46% false negative rate.CONCLUSION: CT LN staging of colon cancer has moderate accuracy, with administration of NCT based on CT potentially resulting in overtreatment. Active search for LN+ may improve sensitivity at the cost of specificity. | Audrey H Choi Rebecca A Nelson Hans F Schoellhammer Won Cho Michelle Ko Amanda Arrington Christopher R Oxner Marwan Fakih Jimmie Wong Stephen M Sentovich Julio Garcia-Aguilar Joseph Kim | 2015 | World Journal of Gastrointestinal Surgery2015，7，7： | 0 |
