Clinical Trial Summary

This is a non-inferiority study in which the investigators compare two low-dose radiotherapy schemes, which are recommended from DEGRO Clinical Practice Guidelines (3 Gy vs 6 Gy) for the treatment of osteoarthritis and other osteodegenerative disorders.

A first randomization will be carried out among the patients included in the study:

• Patients in arm A will be treated at 3 Gy (0.5 Gy/fraction, 3 fractions/week), and patients in arm B will be treated at 6 Gy (1 Gy/fraction, 3 fractions/week).

• Patients should not know the arm to which they have been randomized.

• Once the treatment is finished, patients will be assessed at 8 weeks. If pain does not improve, a re-irradiation will be performed. If the patients were treated with 3 Gy a new randomization will be performed (3 vs 6 Gy again). If the patiens were treated with 6 Gy they will be re-irradiated with 6 Gy again.

The investigators will analyze the results obtained depending on the dose received and depending on the location of the treatment.

Description:

Painfull skeletal disorders are susceptible to be treated with low-dose radiotherapy. DEGRO guidelines recommend a dose between 3 and 6 Gy at 0'5 Gy/fraction or 1 Gy/fraction respectively. The investigators want to verify that both treatments (3 and 6 Gy) are similar to improve the pain and function in patiens with gonarthrosis and coxarthrosis, and there are no differences between both treatments, therefore, 3 Gy is not less than 6 Gy.

In this context, a prospective multicenter study is proposed. The study will include 338 patients to assess the efficacy of low dose irradiation (3 vs 6 Gy) in gonarthrosis and coxarthrosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain control at 8-12 weeks and every 6 months	To evaluate the non inferiority efficacy of low dose radiotherapy 3 or 6 Gy to change in pain with VAS (Visual Analogue Scale). The patient scores his painfrom 0 (no hurt) to 10 (hurts worst). It is better a low score.	At 8-12 weeks, 6 months, 12 months, 18 months and 24 months
Primary	Quality of Life at 8-12 weeks and every 6 months	To evaluate the non inferiority efficacy of low dose radiotherapy 3 or 6 Gy to change in pain with WOMAC scale (Western Ontario MacMaster Questionnaire). This questionnaire has 24 questions about pain, joint stiffness and joint function. It is better a low score.	At 8-12 weeks, 6 months, 12 months, 18 months and 24 months
Secondary	Skin toxicity at 8-12 weeks.	Skin toxicity will be assessed and rated acording to the RTOG scale (0= no change over baseline; 1: Follicular, faint or dull erythema epilation, dry desquamation, decreased sweating; 2: Tender or bright erythema, patchy moist desquamation, moderate oedema; 3: Confluent, moist desquamation other tan skin folds, pitting oedema; 4: Ulceration haemorrhege, necrosis.	At 8-12 weeks.
