Proton beam therapy for lung metastasis of colorectal cancer

A Phase II Study of Curative Proton Beam Therapy for Patients With Lung Metastasis of Colorectal Cancer

NA · National Cancer Center, Korea · NCT03566355

This study tests if proton beam therapy can help patients with lung cancer that has spread from colorectal cancer feel better when surgery isn't an option.

What this trial studies

This clinical trial evaluates the effectiveness of curative proton beam therapy specifically for patients with lung metastasis from colorectal cancer, diagnosed as adenocarcinoma. Participants will receive proton therapy five times a week, totaling 7200 cGy delivered over 15 fractions within three weeks. The study aims to determine if this targeted treatment can improve outcomes for patients who are not suitable for surgery due to various health conditions. It is a prospective, single-organ trial focusing on a specific patient population.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed colon adenocarcinoma and limited lung metastasis who are not suitable for surgery.

Not a fit: Patients with other types of cancer, extensive metastasis, or those who have had recent invasive cancer diagnoses may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive curative option for patients with lung metastasis from colorectal cancer.

How similar studies have performed: While proton therapy is a well-established treatment modality, this specific application for lung metastasis of colorectal cancer is relatively novel and has not been extensively tested in prior studies.
