| 摘 要： | 目的 探讨超声内镜在直肠癌新辅助放化疗后再分期的准确性.方法 61例初诊直肠癌患者纳入研究,新辅助治疗后行超声内镜分期,并与手术后病理分期进行比较.结果放化疗后EUS对直肠癌T分期的总准确率为59.0%(36/61),36.1%(22/61)的病例分期过高,4.9%(3/61)的病例分期过低.EUS对直肠癌N分期准确率为68.9%(42/61),14.7%(9/61)的病例分期过高,16.4%(10/61)的病例分期过低.结论 EUS对新辅助治疗后的直肠癌进行再分期的准确率降低.

| Abstract: | Objective The aim of this study is to evaluate the accuracy of EUS in rectal cancer restaging after neoadjuvant therapy. Methods EUS staging was performed after neoadjuvant therapy in 61 patients who were diagnosed as having local advanced rectal cancer. All patients underwent subsequent surgi-cal resection and complete pathologic staging. Results Compared with pathological staging, the total accura-cy of post-therapy EUS T-staging was 59.0% (36/61). The T-overstaging rate was 36.1% (22/61) and un-derstaging rate was 4.9% (3/61). Accuracy of EUS N-staging was 68.9% (42/61), N-overstaging and un-derstaging rates were 14.7% (9/61) and 16.4% (10/61), respectively. Conclusion The accuracy of EUS restaging for rectal cancer after neoadjuvant therapy is relatively low. |
