2 FIGURE 1 A typical example involving SRT for a 76-year-old man with T1N0 adenocarcinoma. He was treated with HypoFXSRT. (A) Before hypofractionated stereotactic radiotherapy (HypoFXSRT). (B) The calculated dose distribution. The isocenter dose was 75 Gy/10 fractions/5 days, and the tumor was fully enclosed with the 90% dose line. (C) Twelve months after HypoFXSRT, a scarred tumor is rated as a partial response.
