Objective: To observe the short-term effect of whole body gamma knife in the treatment of primary lung cancer. Methods: Totally 78 patients with primary lung cancer underwent gamma knife radiotherapy. The isoforms of 50% to 70% were wound around the margin of the tumor with external enlargement of 10-15 mm and peripheral dose of 500-1000 cGy. The total dose of 36 0 0 ~ 4 2 0 0cGy, points 8 to 4 times, every other day treatment. Results: One to three months after the review, up to 6 months, 78 cases were followed up, of which 62 cases were imaging review.
