Radiotherapy approach for advanced lung cancer patients responding to immunotherapy and chemotherapy

Primary Tumor Radiotherapy Omitting Clinical Target Volume for Patients With Advanced Non Small Cell Lung Cancer Responded to Immunotherapy and Chemotherapy

Not applicable Interventional Hubei Cancer Hospital · NCT06037733

This study is testing if skipping a certain part of radiation treatment can help advanced lung cancer patients who have responded to immunotherapy and chemotherapy avoid lung problems while still keeping their tumors under control.

What this trial studies

This randomized study aims to evaluate the effects of omitting the clinical target volume (CTV) in primary tumor radiotherapy for patients with advanced non-small cell lung cancer (NSCLC) who have responded to immunotherapy and chemotherapy. The study will assess outcomes related to pneumonitis, local tumor control, and overall survival. Previous findings suggest that omitting CTV radiation may reduce the incidence of pneumonitis without compromising local control and survival rates. The goal is to optimize treatment while preserving immune function to enhance the benefits of immunotherapy.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 80 with advanced NSCLC who have shown a positive response to prior chemotherapy and immunotherapy.

Not a fit: Patients with tumor progression after therapy, specific genetic mutations, or significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to reduced side effects and improved survival outcomes for patients with advanced NSCLC.

How similar studies have performed: Previous studies have indicated that omitting CTV radiation does not negatively impact local control or survival, suggesting potential success for this approach.
