美国国家癌症协会(NCI)和一些医学研究所都一致认为,术中放疗是治疗癌症的一种新方法。合理的放射治疗就是在手术时直接照射癌症部位,避免和减少了对敏感的正常组织的照射。近来,Kinsella(NCI)等报告了术中放疗的动物实验和试验性临床研究的结果,指出术中放疗特别适用于腹部和盆腔肿瘤。这些部位的肿瘤,外科手术切除后常见局部控制失败,像胃癌、胰腺癌、直肠癌和腹膜后的肉瘤。
The National Cancer Institute (NCI) and some medical institutes all agree that intraoperative radiotherapy is a new method for treating cancer. Reasonable radiation therapy is to directly illuminate the cancer site during surgery, avoiding and reducing the exposure to sensitive normal tissue. Recently, Kinsella (NCI) et al. reported results of animal experiments and experimental clinical studies of intraoperative radiotherapy, and pointed out that intraoperative radiotherapy is particularly suitable for abdominal and pelvic tumors. Tumors at these sites often fail after local resection, such as gastric cancer, pancreatic cancer, rectal cancer, and retroperitoneal sarcoma.
