title: Stereotactic single high dose irradiation of lung tumors under respiratory gating.
abstract: OBJECTIVE
  To investigate the feasibility of a stereotactic single high dose irradiation of lung tumors under respiratory gating and the clinical response.
  
  
  METHODS
  Twenty-three malignant lung tumors less than 40mm in diameter were treated by a single fractional irradiation.
  
  
  CONCLUSIONS
  Local regrowth was seen in three of ten tumors irradiated less than 30Gy, the minimal dose. Only one regrowth was observed in the tumors treated by 30Gy of with a follow up length of 3-24 months. Apparently 30Gy is able to control the lung tumors with a diameter less than 40mm.
