摘要

新的放疗技术，如HDR和LDR近距离放疗、立体定向放疗、3D-CRT和IMRT，需要准确了解肿瘤的生物学特性，正确定义靶体积。正如两个报告的病例所表明的那样，在特殊技术中相当于2 Gy的公式对于增加GTV总剂量而不损害处于危险中的器官是有用的。

Is one Gy always one Gy? The integration between conventional radiotherapy and special techniques.

The new radiotherapy techniques as HDR and LDR brachytherapy, stereotactic radiotherapy, 3D-CRT, and IMRT require an accurate knowledge of the biological characteristics of the tumor with correct definition of target volumes. As demonstrated by the two reported cases, the formulae equivalent to 2 Gy in the special techniques are useful for the increase in the total dose to GTV while sparing the organs at risk.
