Study Arms (2)

Radiotherapy

EXPERIMENTAL

Patients assigned to the Radiotherapy group are treated with electrons and will receive a total dose of 30 Gy.

Radiation: Radiotherapy

Sham Radiotherapy

PLACEBO COMPARATOR

Patients assigned to the sham-radiotherapy group will not actually receive radiation. For these patients the radiation is simulated.

Other: Sham Radiotherapy

Interventions

RadiotherapyRADIATION

Patients randomized to the Radiotherapy arm will be treated with electrons and receive a total dose of 30 Gy (two separate courses of five daily fractions of 3.0 Gy each).

Radiotherapy

Patients randomized to the sham-radiotherapy will not be treated and the radiotherapy treatment will only be simulated.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with painful Ledderhose disease. The pain score measured with the VAS score and is at least 2 on the 11-point scale (0 = no pain to 10 = worst imaginable pain).
  • Age ≥ 18 years
  • WHO performance status 0, 1 or 2 (Appendix, section 18)
  • Before patient randomisation, written informed consent must be given according to ICH/GCP, and WMO requirements.
  • Controlling the Dutch language (speaking and reading).
  • Able and willing to complete quality of life questionnaires in Dutch
  • Must be accessible for treatment follow-up

You may not qualify if:

  • Surgical intervention before for Ledderhose disease
  • Previous radiation treatment for Ledderhose disease
  • Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule
  • Not able to lay prone for at least fifteen minutes
