目的:探讨内镜检查对食管癌单纯放疗后疗效判断的价值。方法:对中山医科大学肿瘤医院内镜室自1995年1月至1999年12月确诊的食管癌单纯放疗后57例内镜结果分析。结果:局部病灶未控或复发31例(54.4％);放疗后出现良性溃疡2例(3.5％),照射区域内不同程度的充血水肿及病变区域管壁僵硬,灰白色苔样覆盖,管腔轻度狭窄6例(10.5％),16例(28.1％)因病灶区管腔明显狭窄镜身未能进入仅在病灶先端取活检;3例(5.3％)肿块完全消失,粘膜光滑。放疗后发现第2癌5例。结论:食管癌局部未控制和复发是食管癌放疗失败的主要原因:放疗后发现第2癌己被重视;内镜对食管癌放疗后病变的诊断有一定的价值。
Objective: To evaluate the value of endoscopic examination in the evaluation of curative effect of esophageal cancer after radiotherapy alone. METHODS: Endoscopic findings of 57 patients with esophageal cancer diagnosed from January 1995 to December 1999 in the endoscopic department of Cancer Hospital, Sun Yat-sen University of Medical Sciences were analyzed. Results: There were 31 cases (54.4%) with uncontrolled or recurrent local lesions; 2 cases (3.5%) with benign ulcers after radiotherapy; varying degrees of congestion and edema in the irradiated area; stiff wall in the lesion area; grayish white coating covering; The degree of stenosis was 6 (10.5%), and 16 cases (28.1%) failed to enter the apex of the lesion due to the stenosis of the lumen in the lesion area. The tumor disappeared in 3 cases (5.3%) and the mucosa was smooth. After radiotherapy, 5 cases of second cancer were found. Conclusion: The uncontrolled and recurrence of esophageal cancer is the main reason for the failure of esophageal cancer radiotherapy. After the radiotherapy, it is found that the second cancer has been taken seriously; endoscopy has a certain value in the diagnosis of esophageal cancer after radiotherapy.
