Preliminary study of stereotactic radiotherapy for lung cancer

From March 1997 to November 1999, 45 patients with lung cancer were treated by a stereotactic radiotherapy, with 15 cases treated by a stereotactic radiotherapy alone, and 30 cases by the external radiotherapy plus stereotactic radiotherapy. The clinical target volume was 1. 89–187. 26 cm3 with the median being 18. 17 cm3. The doses of plan target volume (PTV) edge was 16–30 Gy/2–3 times and the doses of center was 120 % to 150 % of PTV edge doses. The overall response rate was 84. 4 % (38/45), with 11 complete response (CR) and 27 partial response (PR). This study confirmed that the stereotactic radiotherapy is a safe and effective therapy for lung cancer. For those early-stage patients who can tolerate neither operation nor even conventional radiotherapy for various reasons, it can both achieve therapeutic purpose and improve quality of life.
