Making proton therapy more effective against tumors

Project 3: Enhanced Sensitivity of Tumors to Proton Beam Therapy: Mechanisms and Biomarkers.

NIH-funded research Massachusetts General Hospital · NIH-11184393

We are looking for genomic signs in tumors that show when proton radiation damages cancer cells more than standard radiation, to help personalize treatment for people with cancer.

What this research studies

This project compares the biological effects of proton beams versus standard photon radiation using advanced physics simulations and lab experiments. Researchers will map DNA damage at very high resolution and link those patterns to tumor genomes. The team will search for genomic biomarkers that predict when a tumor is especially sensitive to protons. Work is led by teams at Massachusetts General Hospital and MD Anderson and combines computational, laboratory, and genomic profiling approaches.

Who could benefit from this research

Good fit: People with solid tumors who are being considered for radiation—especially those who can provide tumor samples or undergo genomic testing—are the most relevant candidates.

Not a fit: Patients whose tumors lack the genomic markers identified by this project or who are not receiving proton therapy are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this could help doctors choose or tailor proton therapy for patients whose tumors are most likely to respond, potentially improving tumor control and reducing side effects.

How similar studies have performed: Preclinical studies have suggested that proton biological effectiveness can vary across tumors, but translating genomic biomarkers into clinical decision-making is still a new area.
