摘要
1989.4～1991.5,腔内放射治疗局部复发的食管癌28例,单纯腔内放疗21例,腔内加体外照射7例。剂量参考点为放射源轴中心线10mm,腔内放疗剂量700～1000cGy/次,每7～10天一次,总共2～4次。病变基本消失5例(18％),明显缩小13例(46％),改善6例(21％),不变2例(7％),疗后无X片不能评价2例(7％)。疗首无溃疡,疗后出现溃疡3/19(16％),疗前有溃疡,疗后溃疡消失2/9例(22％),溃疡缩小4/9例。疗前后有溃疡,疗后发生穿孔率为22％(2/9)。疗前无溃疡,疗后发生穿孔率为16％(3/19)。单纯腔内放疗的平均生存期6.7±4.2月,腔内加体外照射为8.2±4.2月。
From 1989 to 1991, 28 patients with postradiation recurrent carcinoma of esophagus were treated by MSH. 21 patients were treated by intracavitary alone and 7 patients by combined external beam with MSH. The doses varied from 7 to 10 Gy 1 cm from the source-axis, 1 F/7-10 days, totaling 2-4 F/patient. Bariom meal showed CR in 19%(5/28), PR in 67%(19/28), and NR in 7%(2/28) patients. Except 2 patients (7%) who had not X-ray film after treatment, 16%(3/ 19) patients developed crater after-wards. In 6 patients who had crater before MSH, the crater disappeared in 2 (22%) , improved in 4 and perforated in 2 (22%). Those without craters beforehand, perforation developed in 16%(3/19). MSH alone gave a median survival of 6. 7 ±4. 2 months while MSH + external irradiation gave 8. 2 ±4. 2 months.
