The examination of between the electrophysiological phenomenonand the dose volume histogram by carbon ion radiation exposure of the heart

我们对接受纵隔碳离子辐射（CIR）的患者进行24小时心电图检查，并评估心脏在CIR照射下的心电图现象与辐射剂量的关系。我们使用剂量-体积直方图来量化CIRT的暴露。但心律失常的存在与CIRT的最大/平均剂量之间没有相关性。本研究报告1例原发性心脏恶性肿瘤。我们的CIRT可以表明这种致命疾病的安全性和高度的肿瘤控制性。这一结果可能为治疗这种缺乏标准化策略的极端罕见疾病提供有用的信息。

We examined 24 hours electrocardiography to the patients who received carbon ion radiation (CIR) to the mediastinum, and assessed the relation between the electrocardiographic phenomenon and the radiation dose in CIR exposure of the heart. We quantified the exposure of CIRT by using the dose-volume histogram. But there was no correlation between the presence of arrhythmia and the maximum/average dose of CIRT. In this study, one case of primary cardiac malignant tumor was registered. Our CIRT could indicate the safety and the high tumor control for this lethal disease. This result may be useful information for the treatment of this extreme rare disease which lacks of standardized strategies.
