摘要: Abstract Effective radiotherapy for extensive angiosarcomas of the face and scalp is technically difficult due to complex shape volume at risk, which can consist superficial tissues entire head. This work reports details a rotational X-ray technique used deliver large part tumour dose. The consists four consecutive 90° arcs with changing centre blocks protect critical midline structures. Multilevel CT based treatment planning carried out determine block dimensions beam weights. As result radiation dose delivered acceptable uniformity over shell overall combines fields lateral field irradiation and/or local boosts photons or electrons. Two three patients treated this had control disease until their deaths 13 18 months. A third patient responded well, only small region stable ...
