Summary
Brief summary (as posted)
Radical radiotherapy is critical for locally advanced non small cell lung cancer(NSCLC ). Our previous sturdy indicated that patients who received induction immunotherapy and subsequent radiotherapy suffered higher proportion of pneumonitis.Grade 2 or more pneumonitis patients have worse prognosis. It is urged to optimize the radiotherapy dose and target volume for patients treated with immunotherapy and radiotherapy. According to retrospective and prospective studies, omitting CTV radiation is feasible for patients undergoing concurrent radio-chemotherapy for locally advanced NSCLC. It is postulated that omitting CTV radiation for patients responded to induction therapy with immunotherapy and chemotherapy will have less pneumonitis without sacrificing the local control rate. Omitting CTV may also retain better immune function which will facilitate the immunotherapy.
