NICE encourages further research into radiation therapy for early Dupuytren's disease, including randomised controlled trials. Because of the uncertainty over the natural history of the disease, this should include studies comparing the long-term efficacy of radiation therapy with no radiation therapy. Studies should include details of patient selection, stage of disease progression, duration and types of treatment, patient-reported outcomes, and long-term efficacy and safety data. NICE may update the guidance on publication of further evidence.
