CT对食管癌分期的价值

The role of computed tomography in preoperative staging of esophageocarcinoma

目的 分析食管癌的CT表现,以便进行其分期。方法 分析25例手术及病理证实的食管癌胸部及上腹部的CT表现,包括病变的范围、周围纵隔结构的侵犯、淋巴结及纵隔外脏器的转移情况。结果 CT表现与病理检查的结论进行比较(其中21名进行食管癌切除手术),CT判断食管癌对纵隔脏器的侵犯的正确率90.48％(19/21),食管癌引起周围淋巴转移情况的正确率为76.42％(15/21)。4例CT检查发现有远处转移,避免了不必要的手术治疗。结论 CT检查对食管癌的术前分期,对病变范围进行评估,对降低不必要的手术治疗较为有效。

Purpose To study the CT manifestation of esophageal carcinoma for staging. Methods The findings of CT in the chest and upper abdomen of 25 patients with esophageal carcioma where compared with pathologic findings obtained during a curative procedure with tissue sampling. Results All results were compared with the findings at pathologic examination of resected specimens . In 21 patients who underwent curative esophagectomy CT accurately revealed the invasion of adjacent medi-astinal structure in 90.48%(15/21) and in four patients CT revealed metastasis. All patients avoided needless surgery.Conclusion The use of CT in the staging of eseophageal carcinoma may be effective by decreasing the number of unnecessary surgeries in patients with unresectable tumors.
