前言晚期肿瘤通常伴有全身播散和骨胳转移,给病人带来极大痛苦,也是造成病人全身衰竭和死亡的重要原因之一。临床对肿瘤限局性转移采用化学治疗或补丁式照射收到一定效果,但对全身播散尤其是广泛骨胳转移造成的疼痛治疗办法甚少。在这种情况下,化学治疗和其它治疗肿瘤的方法往往无济于事,病人只有靠麻醉药物止痛。因此,寻求治疗晚期肿瘤疼痛的有效方法是肿瘤临床医生的重要任务之一。半身照射是近年来治疗播散性肿瘤疼痛的一种新方法,是补丁式照射和全身照射技术的发展。它将身体分成两个大部分,即上半身和下半身来进行照射,每次照射剂量为300～1000拉德,如有必要在骨髓恢复之后再进行另外半身照射,通常间隔4～6周。这
Introduction Advanced tumors are usually accompanied by systemic dissemination and bone metastases, causing great suffering for patients, and are also one of the important causes of systemic failure and death. The clinical use of chemotherapy or patch-type irradiation for tumor-limited local metastases has received certain results, but there are few methods for the treatment of pain caused by systemic dissemination, especially extensive bone metastasis. In this case, chemotherapy and other methods of treating tumors often do nothing, and patients only rely on narcotic drugs to relieve pain. Therefore, it is one of the important tasks of oncologists to seek effective methods for treating advanced tumor pain. Half-body irradiation is a new method for treating disseminated tumor pain in recent years, and is the development of patch-type irradiation and whole body irradiation techniques. It divides the body into two major parts, namely the upper body and the lower body. Each dose is between 300 and 1000 rads. If necessary, after the bone marrow is restored, another half body irradiation is performed, usually at intervals of 4 to 6 weeks. This
