Quality of life after palliative radiotherapy in bone metastases: A literature review.

Objective: To investigate the quality of life (QOL) following palliative radiotherapy for painful bone metastases.

Methods: A literature search was conducted in OvidSP Medline (1946-Jan Week 4 2014), Embase (1947-Week 5 2014), and the Cochrane Central Register of Controlled Trials (Dec 2013) databases. The search was limited to English. Subject headings and keywords included 'palliative radiation', 'cancer palliative therapy', 'bone metastases', 'quality of life', and 'pain'. All studies (prospective or retrospective) reporting change in QOL before and after palliative radiotherapy for painful bone metastases were included.

Results: Eighteen articles were selected from a total of 1730. The most commonly used tool to evaluate QOL was the Brief Pain Inventory. Seventeen studies collected data prospectively. An improvement in symptoms and functional interference scores following radiotherapy was observed in all studies. The difference in changes in QOL between responders and non responders was inconsistently reported.

Conclusion: QOL improves in patients who respond to palliative radiotherapy for painful bone metastases.
