A National Phase II Study of Proton Therapy in Hepatocellular Carcinoma

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 50 (estimated)
• Sponsor: University of Aarhus · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

350 new cases of hepatocellular carcinoma (HCC) are diagnosed in Denmark each year, but the overall prognosis is poor with a 1-year survival rate of less than 40% and a 5-year survival rate of 10% for the entire patient group. This national phase II non-randomized single-arm study of proton therapy in HCC is conducted with the aim to offer a safe and efficient radiation treatment to fragile patients with reduced dose to the normal liver compared to conventional photon-based radiotherapy.

Detailed description

Each year, approximately 350 new cases of hepatocellular carcinoma (HCC) are diagnosed in Denmark, but the overall prognosis is poor with a 1-year survival rate of less than 40% and a 5-year survival rate of 10% for the entire patient group. This national phase II non-randomized single-arm study of proton therapy in HCC is conducted with the aim to offer a safe and efficient radiation treatment to fragile patients with reduced dose to the normal liver compared to conventional photon-based radiotherapy. The study aims to offer curative treatment to a larger group of patients and thus better prognosis for these patients. The study will include 50 patients enrolled within 3 years. Patients cannot be guaranteed any direct personal benefits of participating in the trial. Participating in the study can help with new knowledge that can benefit future patients with similar illness. The treatment will be given at the Danish Center for Particle Therapy. During radiotherapy, additional CT scans will be performed weekly as part of quality assurance until it can be documented that there is no such need. Participation in the study will also mean additional examinations and questionnaires at the start of treatment, below treatment and at follow-up. All patients will be asked to supply blood samples to analyze for circulating tumor DNA.
