Based on the experience of stereotactic irradiation of lung and liver tumors the feasibility of stereotactic boost irradiation to abdominal and pelvic tumors was evaluated. Twenty-one patients with inoperable tumors received a stereotactic boost of 2-3 x 5Gy/PTV-enclosing-100% isodose with normalization to 150% at the isocenter after normofractionated irradiation of 45-50.4Gy. Actuarial local control (16/21 targets) was 96/70% after 12 and 24 months. Treatment was feasible and well tolerated.
基于肺部和肝脏肿瘤立体定向放射治疗的经验，对腹部和盆腔肿瘤进行立体定向追加放射治疗的可行性进行了评估。21例无法手术的肿瘤患者在接受45-50.4Gy常规分割照射后，接受了2-3次5Gy/PTV-包绕-100%等剂量线的立体定向追加照射，等中心剂量归一至150%。12个月和24个月时的精算局部控制率（16/21个靶区）分别为96%/70%。治疗可行且耐受性良好。
