MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Radiation treatment has been demonstrated in numerous studies to provide effective and timely pain relief to those suffering from painful bone metastases. However, as a palliative treatment, the goal should be not only to reduce pain but also to maintain and even improve quality of life. To date, studies have not effectively demonstrated this; most of these have included either small sample sizes or utilize questionnaires that aren’t tailored to the palliative cancer population with bone metastases.
We aimed to determine how soon after radiation treatment one can expect an improvement in quality of life. Our results showed that patients who had a pain response to radiation also had significantly greater improvements in pain, pain characteristics, functional interference, and psychosocial aspects of well-being at day 10 post-treatment. Further improvements in most domains of quality of life were found for responders at day 42.
