Low-Dose Radiation Safely Relieves Arthritis Pain

 

German researchers, who followed more than 4,600 elderly patients who received radiation therapy for arthritis between 1994 and 2010, reported only three possible solid tumor cancer diagnoses over 15 years of follow-up. Two of these were basal cell carcinoma, a type of skin cancer.

  • Three research teams from San Francisco stated during the annual meeting of
  •  the "American Society for Radiation Oncology" that using this low-dose
  •  therapy is a safe and effective option for treating mild to moderate arthritis
  •  conditions.

A randomized trial conducted

 in Korea involving 114 volunteers with knee arthritis showed that those who received three gray units of radiation over six sessions experienced a significant reduction in pain and improved physical function. In contrast, radiation doses typically used after breast and head and neck cancer surgeries range between 45 and 60 gray.

 

  1. After four months, results showed a significant 70% improvement in at least
  2.  two of three indicators—pain, physical function, and general condition—
  3. after receiving low-dose radiation, compared to 42% after undergoing a
  4.  placebo procedure with no actual effect.

 

Researchers also found that receiving a very low dose of

radiation (0.3 gray) was no more effective than the placebo procedure.

 

Separately,

 American researchers reported that 84% of 103 patients who received radiation therapy for arthritis in their hands, knees, or other body areas experienced an improvement in pain levels. Results showed that pain relief rates were similar across different joints, body weights, and genders.

 

Dr. Byeong Hyeok Kim from Seoul National University College of Medicine, who led the Korean study, stated that low-dose radiation therapy is regularly used to treat

joint pain in Europe, but high-quality evidence based on randomized trials has been limited until now.

 

Kim added that the radiation doses used to treat arthritis are much lower than those used in cancer treatment, and the targeted joints are usually far from vital organs, which reduces the risk of side effects.

 

German researchers, 

who followed more than 4,600 elderly patients who received radiation therapy for arthritis between 1994 and 2010, reported only three possible solid tumor cancer diagnoses over 15 years of follow-up, two of which were basal cell carcinoma. The researchers stated that the results indicate that radiation doses used to treat musculoskeletal pain in the elderly carry a "very low risk of causing solid malignant tumors."

 

However, 1.4% of patients developed leukemia, especially when the treatment was directed near the bone marrow responsible for producing blood cells, suggesting the need for caution when using radiation therapy in the shoulder and torso regions, as advised by the researchers.
