作者于1979年2月至1982年1月对20例局限性的和复发的晚期结肠瘤患者使用全腹延迟分割放疗。每例原发灶均位于乙结肠直肠的交界以上,分根治性放疗和姑息性放疗二组。根治组11例,其中原发灶手术后进行放疗者8例,复发灶切除后进行放疗者3例,姑息组9例均有肝转移。治疗方法:本文全腹放疗分骨盆与上腹前后相对共四野,上下野有一间隙相隔。骨盆野是从闭孔下方起到L_4中心,上腹野由间隙起到横膈上方2厘米处,于模拟时计算出实用野的大小,从而使这些野在中段平面相遇,保证了全腹放疗的一致性。全腹延迟分割放疗即先放疗骨盆野,二小时以后接着
From February 1979 to January 1982, the authors used total abdominal delayed-fractionated radiotherapy for 20 patients with localized and recurrent advanced colon tumors. Each of the primary lesions was located at the junction of the colorectal and rectal rectum, divided into two groups: radical radiotherapy and palliative radiotherapy. There were 11 patients in the radical treatment group, of whom 8 cases were treated with radiotherapy after primary tumor surgery, 3 cases were treated with radiotherapy after resection of recurrent lesions, and 9 cases were treated with hepatic metastasis in the palliative group. Treatment: In this article, total abdominal radiation was divided into four fields: the pelvis and the upper abdomen. There was a gap between the upper and lower fields. The pelvic field is from the obturator hole to the center of L4, and the upper abdomen is 2 cm above the diaphragm from the gap. The size of the practical field is calculated during the simulation, so that these fields meet in the middle plane to ensure the whole abdomen radiotherapy. Consistency. Whole-abdominal delayed-fractionated radiotherapy is the first treatment of the pelvic field, followed two hours later.
