Abstract:
Objective To evaluate the effect of stereotactic radiotherapy combined with conventional radiotherapy for non-small cell lung cancer(NSCLC)patients with positive stump at the resected bronchial margin. Methods From June 1996 to November 2000, 41 NSCLC patients in whom microscopic residual disease found pathologically at the resected bronchial margin were treated by: conventional radiotherapy followed by stereotactic radiotherapy ( RT+SRT group 18 patients), while the other 23 patients received routine radiotherapy alone (RT group). Results The 1-,2-and 3-year local disease-free rates were better in RT+ SRT group (92.3%,~83.1% and 83.1%) than those in RT group (80.2%,60.2% and 39.5% ). However, no significant difference was found in the complication rate or survival rate between the two groups. Conclusions Stereotactic radiotherapy is effective as a boost irradiation to patients with non-small cell lung cancer with microscopic residual disease at the resected bronchial margin by improving the local control.
