本文选择32例食管癌根治放疗后病人进行了χ线、内镜及活检病理的综合研究。结果表明,χ线近期疗效基本消失12.5％,明显缩小46.9％,改善35.3％,无变化9.3％。放疗后出现新溃疡3例(9.3％)。所有病例内镜均见受照射区域内食管粘膜不同程度的充血水肿及病变区域的管壁僵硬,并可见灰白色苔样覆盖。病理轻度治疗反应15.6％,中度治疗反应28.1％,重度治疗反应56.3％,残留癌细胞检出率43.7％。食管癌放疗后组织治疗反应与近期疗效评价结果成正比,与残留癌细胞检出率成反比。
This article selected 32 patients with esophageal cancer after radical radiotherapy to carry out a comprehensive study of the squall line, endoscopy and biopsy pathology. The results showed that the recent curative effect of the squall line basically disappeared 12.5%, significantly reduced 46.9%, improved 35.3%, no change 9.3%. There were 3 new ulcers (9.3%) after radiotherapy. In all cases, endoscopy showed congestive edema of different degrees of esophageal mucosa in the irradiated area, and the stiffness of the wall of the lesion area, and gray-white moss-like coverage. The pathological mild treatment response was 15.6%, the moderate treatment response was 28.1%, the severe treatment response was 56.3%, and the residual cancer cell detection rate was 43.7%. The tissue treatment response after radiotherapy for esophageal cancer is directly proportional to the results of the short-term efficacy evaluation and is inversely proportional to the detection rate of residual cancer cells.
