Clinical trial including OU patients finds proton therapy improves head, neck cancer survival
🔬 New Clinical Trial Shows Proton Therapy Can Improve Survival
A recent Phase III clinical trial — including patients treated at the University of Oklahoma — found that proton therapy can help people with certain head and neck cancers live longer and have fewer treatment side effects compared with standard radiation therapy.
📍 What Was Studied
The research looked at people with oropharyngeal cancer — a type of head and neck cancer that affects areas like the tonsils and back of the tongue.
Patients were split into two groups:
One group received proton therapy
The other got standard photon radiation therapy (the most common type of radiation)
📈 Main Findings
1. Higher Survival Rates
After 5 years, people treated with proton therapy had a 10% higher overall survival rate than those who received standard radiation.
2. Fewer Treatment Side Effects
Doctors noticed that proton therapy seemed to cause less damage to healthy tissue, which likely helped patients stay healthier overall during and after treatment.
3. Why Proton Therapy May Be Better
Protons are particles that can be controlled so that most of the radiation stops right at the tumor, reducing exposure to nearby normal cells. Traditional X-ray radiation continues through the body and can affect more healthy tissue.
This reduction in radiation to normal tissue may:
Protect the immune system better
Reduce irritation and inflammation in the head and neck
Help people maintain weight and swallow more easily
🧠 What This Means for Patients
This large trial suggests proton therapy might offer an important advantage for people with certain head and neck cancers — not only in survival but also in quality of life during and after treatment.
While more research will continue and access to proton therapy varies by location and insurance, this is one of the strongest pieces of evidence yet showing proton therapy can make a real difference.
🧪 Is proton therapy available in New Zealand’s public health system?
❌ No — proton therapy is not currently offered by the New Zealand public health system.
This means that you cannot get proton beam therapy as a standard publicly funded treatment in New Zealand hospitals right now.
Radiation therapy for cancer in New Zealand almost always uses X-ray-based machines (linear accelerators), which are widely available and effective for many cancers.
🌏 Can people from New Zealand get proton therapy overseas?
Yes — some patients who need or want proton therapy travel to other countries (such as Australia or further abroad) for that treatment. But this is usually done privately — meaning it’s not publicly funded by the New Zealand health system.
That also means:
You might need private health insurance, a fundraising campaign, or self-funding to cover the costs.
Your doctor or radiation oncologist would need to help arrange referrals and logistics.
💡 Why isn’t proton therapy available here yet?
Proton therapy equipment is very expensive to build and run. New Zealand’s public health system focuses on radiation treatments that can be delivered more widely with current technology. Improvements in traditional radiation (like IMRT and CyberKnife) are happening locally, but proton beam therapy services haven’t been established yet.
📌 What this means for head and neck cancer patients
Even though proton therapy isn’t available publicly in New Zealand yet:
Standard radiation therapy (like IMRT) is still a proven and effective treatment for many head and neck cancers.
If proton therapy is recommended for a specific situation, some patients do pursue referral and treatment overseas, but this usually requires private funding or support.
