Objective To analyze the therapeutic effect of X-knife on lung tumors. Methods Thirty-four patients with malignant lung tumors (15 squamous cell carcinomas, 5 adenocarcinomas, 10 small cell lung cancers, and 4 metastatic carcinomas) received conventional external irradiation (field-to-field irradiation) after 40 Gy and rested 5 to 7 times. Days, line X-knife treatment, with an average exposure dose of 30 Gy (24 to 40 Gy). Results One to three months after the treatment, CT and MRI showed that among the 30 primary lung tumors, 26 tumors shrank or disappeared, 4 did not change, and 4 metastatic cancer masses shrank significantly. Six patients died within 12 months of treatment in all patients. Conclusion X-knife is effective in the treatment of lung tumors. X-knife combined with conventional radiotherapy is beneficial for the local control of lung tumors.
