Intraoperative electron-beam radiation therapy (IRT) is being used to treat certain abdominal malignancies. Accurate determination of tumor size, depth, and extent is necessary to select a treatment cone of appropriate size and appropriate electron beam energy for the treatment portal. Fourteen patients undergoing evaluation for this treatment were examined with intraoperative ultrasonography (IUS) to aid therapy planning. IUS study required little additional time and readily delineated tumor size, depth, and relationship to adjacent structures. In two patients, the US and operative findings provided information that precluded use of IRT. The traditional method of tumor evaluation by intraoperative palpation and inspection was consistently enhanced by the use of IUS findings. IUS is a valuable adjunct that improves the accuracy of therapy planning for IRT.
术中电子束放射治疗（IRT）正被用于治疗某些腹部恶性肿瘤。准确确定肿瘤的大小、深度和范围对于选择合适尺寸的治疗锥以及治疗野合适的电子束能量至关重要。对14例接受该治疗评估的患者进行了术中超声检查（IUS）以辅助治疗计划制定。IUS检查几乎不需要额外时间，并且能很容易地勾勒出肿瘤的大小、深度以及与相邻结构的关系。在2例患者中，超声检查结果和手术所见提供的信息排除了IRT的使用。术中触诊和检查这种传统的肿瘤评估方法因使用IUS检查结果而始终得到加强。IUS是一种有价值的辅助手段，可提高IRT治疗计划的准确性。
