直肠癌术前CT分期与术后病理比较研究

目的探讨直肠癌术前CT分期与术后病理表现的关系.方法收集了经手术病理证实的直肠癌患者52例,分析其CT表现,并与术后病理结果对照.结果CT对侵犯深度判定的准确率达88.5%,对转移淋巴结判定的准确率达96%,能够很好显示病变范围、侵润程度、周围器官受侵及淋巴结转移情况.CT分期与病理分期基本相符.结论通过直肠癌的CT征象分析,对于术前推断肿瘤的恶性程度及患者的预后有重要价值.

Comparative Study Between Preoperative CT Staging and Postoperative Pathologic Findings in Rectal Cancer

Objective the correlation between preoperative CT staging and postoperative pathologic findings was explored. Methods 52 patients with rectal cancer confirmed by pathology were collected. CT appearance in rectal cancer was analysed, and compared with pathologic findings. Results CT diagnostic accuracy for the depth of invasion were 88.5%, for the lymph node metastasis were 96%, and the tumor size, depth of invasion, neighbour organ infiltration and the lymph node metastasis were showed well. Conclusion It is of important value in assessing the degree of malignancy and patients' prognosis that preoperative analysis of CT appearance in rectal cancer.
