Proton therapy for reducing side effects in lung cancer treatment

Proton Therapy to Reduce Acute Normal Tissue Toxicity in Locally Advanced Non-small-cell Lung Cancer

Not applicable Interventional Technische Universität Dresden · NCT02731001

This study is testing whether proton therapy can help people with advanced lung cancer experience fewer severe side effects from radiation treatment compared to traditional photon therapy.

What this trial studies

This study aims to compare the effectiveness of proton therapy versus photon therapy in reducing acute radiation-induced side effects, such as pneumonitis and esophagitis, in patients with locally advanced non-small cell lung cancer (NSCLC). Patients will be randomly assigned to receive either intensity-modulated radiotherapy with photons or proton therapy, both combined with chemotherapy. The primary goal is to demonstrate a significant reduction in the incidence of severe side effects associated with radiation therapy. Secondary objectives include assessing quality of life, loco-regional control, survival rates, and late radiation-induced side effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with locally advanced NSCLC who are medically suited for primary radiochemotherapy.

Not a fit: Patients with early-stage tumors suitable for stereotactic radiotherapy or those with significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of severe side effects from radiation therapy, improving the quality of life for lung cancer patients.

How similar studies have performed: Previous studies have shown promising results with proton therapy in reducing side effects, suggesting a potential for success in this approach.
