高剂量率远程(HDR)近距离放射治疗消除了对人员的辐射暴露危险，允许最佳剂量计划(剂量学)，并在几分钟内将高辐射剂量提供给肿瘤附近。导尿管可以结合到模具内的固定几何形状中，允许重复治疗，而不需要重复植入放射性同位素或重复剂量测定。本文介绍了HDR近距离放射治疗头颈癌的3例患者，以说明HDR近距离放射治疗在以下情况下的优势：(A)用于门诊治疗，(B)作为外照射的补充或加强，(C)保护局部结构的功能，(D)优化剂量学，(E)用于缓解。它需要放射肿瘤学家、头颈外科医生、牙科肿瘤学家和/或颌面部修复师之间的密切互动，以实现患者的最佳利益。
High-dose-rate remote (HDR) brachytherapy eliminates radiation exposure hazard to personnel, allows for optimum dosage planning (dosimetry), and delivers high radiation dose close to the tumor in only a few minutes. The catheters can be incorporated into a fixed geometry within a mold, allowing for repeated treatments without the need for repeated implantation of radioactive isotopes or repeated dosimetry. This article presents the use of HDR brachytherapy in three patients to illustrate the advantages of HDR brachytherapy for the treatment of head and neck cancers in the following circumstances: (a) for outpatient therapy, (b) as an addition to or potentiation of external beam irradiation, (c) for preservation of function of regional structures, (d) for optimization of dosimetry, and (e) for palliation. It requires close interaction among the radiation oncologist, head and neck surgeon, and the dental oncologist and/or maxillofacial prosthodontist in order for optimum benefit for the patient to be achieved.
