Objective: To evaluate the feasibility of the whole body gamma knife in the treatment of malignant solid tumors. Methods: 643 patients diagnosed by pathology or cytology were treated with the whole body gamma knife. They received a total dose from 40-60 Gy/2-3 w, 3-10 Gy/fraction, 5 fractions/week. Results: The rates of response, complete remission, partial remission, no remission, and tumor progression were 94.6%, 39.2%, 55.4%, 5.1% and 0.3%, respectively. Conclusion: Whole body γ-radiation system (y-knife) was an effective method in treatment of patients with malignant tumor.
