摘　　要：目的：报道立体定向放射治疗体部恶性肿瘤的近期疗效。方法：对原采用放射治疗的病变，如肺癌，分次立体定向放射作为追加剂量，每次5～7Gy，共4～7次；对原不适合放射治疗的病变，如胰腺癌，则单用立体定向放射治疗，每次5～7Gy，共6～7次。结果：总有效率为66．7％，4例死亡。3例胰腺癌均于治疗后5～6个月死于肿瘤未控。6例脊椎转移瘤疼痛症状均完全缓解。结论：立体定向放射治疗可得到良好的姑息甚至根治的疗效；可在不增加正常组织合并症的基础上较大幅度地提高肿瘤局部剂量。Purpose To report the methods and results of stereotactic radiotherapy of malignancies in the thorax and abdomen． Materials and Methods From Nov． 1997 to Sep． 1998 21 patients with malignancies in thorax and abdomen were treated by combined fractionated stereotactic radiotherapy and／or fractionated stereotactic radiation alone． For the tumor which was treated with radiotherapy such as lung cancer the fractionated stereotactic radiotherapy was given as booster of radiotherapy 20～35Gy in 5～7 fractions．． For the tumor not indicated for radiotherapy like cancer of pancreas fractionated stereotactic radiotherapy was given alone for radical or palliative treatment． Results The overall effective rate was 66．7％ 4 cases died and 3 cases of pancreatic cancer died of uncontrolable tumor within 5～6 months but without pain． Conclusion Fractionated stereotactic radiotherapy alone or combined with conventional radiotherapy is effective in the treatment of malignancies of thorax and abdomen．
