Stereotactic single high dose irradiation of lung tumors under respiratory gating

Purpose: To investigate the feasibility of a stereotactic single high dose irradiation of lung tumors under respiratory gating and the clinical response. Methods and materials: Twenty-three malignant lung tumors less than 40 mm in diameter were treated by a single fractional irradiation. Results and...

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