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。
Objective: To report the recent curative effect of stereotactic radiotherapy on malignant tumors of the body. Methods: The original use of radiation therapy lesions, such as lung cancer, fractionated stereotactic radiation as an additional dose, each 5 ~ 7Gy, a total of 4 to 7 times; the original is not suitable for radiation therapy lesions, such as pancreatic cancer alone Stereotactic radiotherapy, each 5 ~ 7Gy, a total of 6 to 7 times. Results: The total effective rate was 66.7%, 4 deaths. Three cases of pancreatic cancer died after 5 to 6 months after treatment. 6 cases of spinal metastases pain symptoms were completely relieved. Conclusion: Stereotactic radiotherapy can achieve good palliative and even radical curative effect. It can significantly increase the local dose of tumor without increasing the normal tissue complications.
