Omitting CTV for Locally Advanced NSCLC Responded to Immunotherapy and Chemotherapy

March 13, 2024 updated by: HAN GUANG, Hubei Cancer Hospital

Omitting CTV Radiotherapy for Locally Advanced Non Small Cell Lung Cancer Responded to Immunotherapy and Radiotherapy

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: CTV-omitted
CTV was omitted for the radical radiotherapy for locally advanced NSCLC who responded to induction therapy with immunotherapy and chemotherapy.
Radiation: CTV omitted or delineated
Patients who responded to the induction therapy (immunotherapy and chemotherapy) were randomly (1:1) assigned into CTV-omitted radical radiotherapy group or CTV-delineated radiotherapy group.
Active Comparator: CTV-delineated
CTV was delineated for the radical radiotherapy for locally advanced NSCLC who responded to induction therapy with immunotherapy and chemotherapy.
Radiation: CTV omitted or delineated
Patients who responded to the induction therapy (immunotherapy and chemotherapy) were randomly (1:1) assigned into CTV-omitted radical radiotherapy group or CTV-delineated radiotherapy group.
