Abstract:
cases were histologically confirmed to be patients with squamous cell carcinoma, 4 cases to be patients with adenocarcinoma. The majority of the patients received stereotatic radiotherapy on the basis of external radiation. The single dose for stereotatic radiation was 5～10Gy, once every two days, 4～8 fractions, the total dose was 26～42 Gy by using 5～6 non-coplanar stationary beams or arc radiation. The patients′ CT was checked 2～3 months after treatment, there were 8 cases of CR( 26.7%), 18 cases of PR(60%),4 case of NR (13.3%).The median survival time was 12 months and the survival of 1 year and 2 years was 84 % and 61.2% (using Kaplan-Meier methods). The total effective rate was 86.7%. The results suggested that stereotatic radiotherapy (SRT) is effective for lung cancer at palliative and radical treatment. Combined with external irradiation, it can increase the doses of target and shorten the course of treatment.
