abstract

  • Purpose We previously demonstrated that 48% of patients with pain at sites of previously irradiated bone metastases benefit from reirradiation. It is unknown whether alleviating pain also improves patient perception of quality of life (QOL). Patients and Methods We used the database of a randomized trial comparing radiation treatment dose fractionation schedules to evaluate whether response, determined using the International Consensus Endpoint (ICE) and Brief Pain Inventory pain score (BPI-PS), is associated with patient perception of benefit, as measured using the European Organisation for Resesarch and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and functional interference scale of the BPI (BPI-FI). Evaluable patients completed baseline and 2-month follow-up assessments. Results Among 850 randomly assigned patients, 528 were evaluable for response using the ICE and 605 using the BPI-PS. Using the ICE, 253 patients experienced a response and 275 did not. Responding patients had superior scores on all items of the BPI-FI (ie, general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life) and improved QOL, as determined by scores on the EORTC QLQ-C30 scales of physical, role, emotional and social functioning, global QOL, fatigue, pain, and appetite. Similar results were obtained using the BPI-PS; observed improvements were typically of lesser magnitude. Conclusion Patients responding to reirradiation of painful bone metastases experience superior QOL scores and less functional interference associated with pain. Patients should be offered re-treatment for painful bone metastases in the hope of reducing pain severity as well as improving QOL and pain interference.
