Abstract
BACKGROUND Compensation mechanisms and multiplier effects may affect productivity losses due to illness, disability, or premature death of individuals. Hence, they are important in estimating productivity losses and productivity costs in the context of economic evaluations of health interventions. This paper presents a systematic literature review of papers focusing on compensation mechanisms and multiplier effects, as well as whether and how they are included in health economic evaluations. METHODS The systematic literature search was performed covering EconLit and PubMed. A data-extraction form was developed focusing on compensation mechanisms and multiplier effects. RESULTS A total of 26 studies were included. Of these, 15 were empirical studies, three studies were methodological studies, two studies combined methodological research with empirical research, four were critical reviews, one study was a critical review combined with methodological research, and one study was a cost-benefit analysis. No uniform definition of compensation mechanisms and multiplier effects was identified. The terminology used to describe compensation mechanisms and multiplier effects varied as well. While the included studies suggest that both multipliers as well as compensation mechanisms substantially impact productivity cost estimates, the available evidence is scarce. Moreover, the generalizability as well as validity of assumptions underlying the calculations are unclear. Available measurement methods for compensation mechanisms and multiplier effects differ in approaches and are hardly validated. CONCLUSION While our review suggests that compensation mechanisms and multiplier effects may have a significant impact on productivity losses and costs, much remains unclear about their features, valid measurement, and correct valuation. This hampers their current inclusion in economic evaluation, and therefore, more research into both phenomena remains warranted.

Abstract
A 72-year-old man with intractable left shoulder pain due to bone metastasis from cholangiocellular carcinoma was admitted to our hospital. Computed tomography showed an osteoblastic metastatic lesion of the left scapula. Since the pain persisted even after the administration of opioids and external irradiation, microspheres were injected through a catheter; the catheter tip was placed at the arteries feeding the metastatic lesion. After the intervention, the shoulder pain was alleviated without any procedure-related complications, leading to a reduction in the opioid dose. This case suggests the efficacy of transcatheter arterial embolization using microspheres for palliating pain from bone metastasis.

Abstract
BACKGROUND There is a paucity of research examining how surgical decision-making for metastatic bone disease (MBD) can be optimized to improve quality of life (QOL) and functional outcomes, while accurately aligning with patient goals and expectations. The objective of this study was to survey and interview patients with MBD and support persons (PS), physicians, and allied health care providers (HCP) with the goal of identifying (1) important surgical issues related to MBD management, (2) discordance in perioperative expectations, and (3) perceived measures of success in the surgical management of MBD. METHODS Utilizing a custom survey developed by HCP and patients with MBD, participants were asked to (1) identify important issues related to MBD management, (2) rank perceived measures of success, and (3) answer open-ended questions pertaining to the management of MBD. RESULTS From the survey, increased life expectancy, minimizing disease progression, removal of local tumour, timely surgery after diagnosis, increased length of hospitalization, and physiotherapy access were all identified as significant discordant goals between PS and physicians/HCP. Conversely, there was an agreement between physicians and HCP who considered improved QOL and functional outcomes as most important goals. Structured homogenous-group workshops identified the need for (1) improved discussions of prognosis, surgical options, expectations, timelines, and resources, (2) the use of a care team "quarterback", and (3) an increased use of multi-disciplinary treatment planning. CONCLUSIONS We feel this data highlights the importance of improved communication and coordination in treating patients with MBD. Further research evaluating how surgical techniques influence survival and disease progression in MBD is highly relevant and important to patients.

Abstract
At our center single fraction radiotherapy is used in accordance with guidelines. Patient age, performance status and tumor histology influence treatment choice. We added a quality indicator to our performance dashboard to improve adherence. This strategy can be used in other complex practices and improve quality of care.
Background Best-practice guidelines recommend single-fraction (SFRT) instead of multi-fraction radiation therapy (MFRT) for uncomplicated symptomatic bone metastases. SFRT is comparable to MFRT in relieving pain, convenient for patients, and cost-effective. Patterns of practice in Canada reveal that SFRT is underused, with significant variability across the country. We audited SFRT use and studied factors that may influence treatment decisions at a large academic tertiary care center in Quebec, Canada. Methods Patients who received radiotherapy for uncomplicated bone metastases between February 2014 and March 2015 were reviewed. Age, gender, primary histology, site of metastases and performance status were identified as potential factors affecting fractionation. These were explored by Fisher's test on univariate analysis and logistic regression for multivariate analysis. Retreatment rates were analyzed with cumulative incidence and compared with Gray's test. Results 254 radiotherapy courses were administered to 165 patients, 85.4% of which were delivered using a single fraction of 8 Gy. Patients age less than 70 years and those with breast histology were more likely to receive MFRT (p = 0.04; p = 0.0046). Performance status (ECOG) was a significant predictor of fractionation because of high correlations between young age, breast histology, and ECOG status (p = 0.03). Follow-up was too short in 40% of patients to derive definitive conclusions on retreatment. Conclusions In accordance with current guidelines, our audit confirms that use of SFRT in patients with uncomplicated bone metastases at our center is high. We identified that patient age, primary histology, and performance status influenced fractionation. Incorporation of this quality indicator into our performance dashboard will allow assessment of retreatment differences and other criteria that may also influence treatment choice.

Abstract
Aims and background In 75% of the patients with bone metastases (BM) pain is the dominant symptom. Radiotherapy (XRT) plays a major role in the palliation of pain in patients with BM. Several schedules of short and long fractionation XRT are used in clinical practice, with hypofractionated treatments being even more attractive for practical reasons. A considerable body of evidence supports the clinical use of short schedules and single-dose XRT. We retrospectively evaluated the efficacy of two short fractionated schedules of 8 Gy as a single dose and 20 Gy in 5 fractions in relieving pain in patients with multiple uncomplicated BM. Method From January to December 2001, 130 patients with 146 painful BM were treated with palliative localized XRT. There were 42 males and 88 females with a median age of 58 years (range 28–84). The commonest sites of treatment were the spine (59.6%) and pelvis (14.4%). The primary endpoint was clinically significant pain relief in the first six months of follow-up evaluated with the IAEA (International Atomic Energy Agency) pain measurement score measuring pain severity and pain frequency. Analgesic use was also recorded before and after treatment as drug frequency and drug severity. Patients with painful BM from any primary tumor site were irradiated. Treatment schedules consisted of a course of XRT with 4 Gy/fraction/day (total dose: 20 Gy/5 fractions) (group A, 59 lesions) or with a single dose of 8 Gy (group B, 87 lesions). Results There was no significant difference in complete response (CR) rates between treatment schedules: complete pain relief was achieved in 17/59 lesions (29%) in the fractionated group and in 29/87 lesions (33%) in the single-dose group. Also the overall response (complete + partial) was similar: 35/59 lesions (60%) in group A and 60/87 (69%) in group B. The minimum, maximum and median follow-up was 3, 23, and 9 months, respectively, for group A and 3, 20, and 11 months for group B. The actuarial median duration of pain relief was similar: 4.5 months in group A and 4 months in group B. No particular side effects were recorded in either group. Conclusions There were no differences between the two fractionation schedules used in our study with regard to pain relief and use of analgesics. Palliation of pain was obtained in approximately two thirds of patients with both schedules, providing further evidence of the similar efficacy between single and multiple fractions. With regard to pain response these data justify a recommendation for the use of a more simple and convenient 8 Gy single fraction for the palliation of uncomplicated BM.

What Factors are Associated With Quality Of Life, Pain Interference, Anxiety, and Depression in Patients With Metastatic Bone Disease? Clin Orthop Relat Res 2017; 475:498-507. [PMID: 27752988 PMCID: PMC5213947 DOI: 10.1007/s11999-016-5118-3] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Accepted: 10/04/2016] [Indexed: 01/31/2023]
Abstract
BACKGROUND It would be helpful for the decision-making process of patients with metastatic bone disease to understand which patients are at risk for worse quality of life (QOL), pain, anxiety, and depression. Normative data, and where these stand compared with general population scores, can be useful to compare and interpret results of similar patients or patient groups, but to our knowledge, there are no such robust data. QUESTIONS/PURPOSES We wished (1) to assess what factors are independently associated with QOL, pain interference, anxiety, and depression in patients with metastatic bone disease, and (2) to compare these outcomes with general US population values. METHODS Between November 2011 and February 2015, 859 patients with metastatic bone disease presented to our orthopaedic oncology clinic; 202 (24%) were included as they completed the EuroQOL-5 Dimension (EQ-5DTM), PROMIS® Pain Interference, PROMIS® Anxiety, and PROMIS® Depression questionnaires as part of a quality improvement program. We did not record reasons for not responding and found no differences between survey respondents and nonrespondents in terms of age (63 versus 64 years; p = 0.916), gender (51% men versus 47% men; p = 0.228), and race (91% white versus 88% white; p = 0.306), but survey responders were more likely to be married or living with a partner (72%, versus 62%; p = 0.001). We assessed risk factors for QOL, pain interference, anxiety, and depression using multivariable linear regression analysis. We used the one-sample signed rank test to assess whether scores differed from US population averages drawn from earlier large epidemiologic studies. RESULTS Younger age (β regression coefficient [β], < 0.01; 95% CI, 0.00-0.01; p = 0.041), smoking (β, -0.12; 95% CI, -0.22 to -0.01; p = 0.026), pathologic fracture (β, -0.10; 95% CI, -0.18 to -0.02; p = 0.012), and being unemployed (β, -0.09; 95% CI, -0.17 to -0.02; p = 0.017) were associated with worse QOL. Current smoking status was associated with more pain interference (β, 6.0; 95% CI, 1.6-11; p = 0.008). Poor-prognosis cancers (β, 3.8; 95% CI, 0.37-7.2; p = 0.030), and pathologic fracture (β, 6.3; 95% CI, 2.5-7.2; p = 0.001) were associated with more anxiety. Being single (β, 5.9; 95% CI, 0.83-11; p = 0.023), and pathologic fracture (β, 4.4; 95% CI, 0.8-8.0; p = 0.017) were associated with depression. QOL scores (0.68 versus 0.85; p < 0.001), pain interference scores (65 versus 50; p < 0.001), and anxiety scores (53 versus 50; p = 0.011) were worse for patients with bone metastases compared with general US population values, whereas depression scores were comparable (48 versus 50; p = 0.171). CONCLUSIONS Impending pathologic fractures should be treated promptly to prevent deterioration in QOL, anxiety, and depression. Our normative data can be used to compare and interpret results of similar patients or patient groups. Future studies could focus on specific cancers metastasizing to the bone, to further understand which patients are at risk for worse patient-reported outcomes.

Abstract
For nearly 100 years, palliative radiotherapy has been a time-efficient, effective treatment for patients with metastatic or advanced cancer in any area where local tumors are causing symptoms. Short courses including a single fraction of radiotherapy may be effective for symptom relief with minimal side effects and maximization of convenience for patient and family. With recent advances in imaging, surgery, and other local therapies as well as systemic cancer therapies, palliative radiotherapy has been used frequently in patients who may not yet have symptoms of advanced or metastatic cancer. In this setting, more prolonged radiotherapy courses and advanced radiotherapy techniques including intensity-modulated radiotherapy (IMRT) or stereotactic radiotherapy (SRT) may be useful in obtaining local control and durable palliative responses. This review will explore the use of radiotherapy across the spectrum of patients with advanced and metastatic cancer and delineate an updated, rational approach for the use of palliative radiotherapy that incorporates symptoms, prognosis, and other factors into the delivery of palliative radiotherapy.

Abstract
PURPOSE Randomized data suggest that single-fraction or short-course palliative radiation therapy (RT) is sufficient in the majority of patients with metastatic cancer. We investigated population-based patterns in the use of palliative RT among patients with metastatic non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS From patients diagnosed with lung cancer from 2003 to 2005 at a participating geographic or organizational site and who consented to the Cancer Care Outcomes Research and Surveillance Consortium study, we identified patients with metastatic NSCLC who had complete medical records abstractions. Patient characteristics and clinical factors associated with receipt of palliative RT and RT intensity (total dose and number of treatments) were evaluated with multivariable regression. RESULTS Of 1,574 patients with metastatic NSCLC, 780 (50%) received at least one course of RT, and 21% and 12% received RT to the chest and bone, respectively. Use of palliative RT was associated with younger age at diagnosis and receipt of chemotherapy and surgery to metastatic sites. Among patients receiving palliative bone RT, only 6% received single-fraction treatment. Among patients receiving palliative chest RT, 42% received more than 20 fractions. Patients treated in integrated networks were more likely to receive lower doses and fewer fractions to the bone and chest. CONCLUSION When palliative RT is used in patients with metastatic NSCLC, a substantial proportion of patients receive a greater number of treatments and higher doses than supported by current evidence, suggesting an opportunity to improve care delivery.

Abstract
AIMS To update previous meta-analyses of randomised palliative radiotherapy trials comparing single fractions versus multiple fractions. MATERIALS AND METHODS All published randomised controlled trials comparing single fraction versus multiple fraction schedules for the palliation of uncomplicated bone metastases were included in this analysis. Odds ratios and 95% confidence intervals were calculated for each trial. Forest plots were created using a random effects model and the Mantel-Haenszel statistic. RESULTS In total, 25 randomised controlled trials were identified. For intention-to-treat patients, the overall response rate was similar in patients receiving single fractions (1696 of 2818; 60%) and multiple fractions (1711 of 2799; 61%). Complete response rates were 620 of 2641 (23%) in the single fraction arm and 634 of 2622 (24%) in the multiple fraction arm. No significant difference was seen in overall or complete response rates. Pathological fracture did not favour either arm, but spinal cord compression trended towards favouring multiple fractions; however, neither was statistically significant (P = 0.72 and P = 0.13, respectively). Retreatment rates favoured patients in the multiple fraction arm, where the likelihood of requiring re-irradiation was 2.6-fold greater in the single fraction arm (95% confidence interval: 1.92-3.47; P < 0.00001). Repeated analyses excluding drop-out patients did not alter these findings. In general, no significant differences in acute toxicities were seen. CONCLUSION Overall and complete response rates were similar in both intention-to-treat and assessable patients. Single and multiple fraction regimens provided equal pain relief; however, significantly higher retreatment rates occurred in those receiving single fractions.

Abstract
Skeletal morbidity is common in patients with bone metastases from breast cancer (BC) and can undermine patients' functional independence and quality of life. Previously defined prognostic factors may not reflect current treatment standards and the use of antiresorptive therapies. We report a comprehensive multivariate analysis of potential prognostic factors for skeletal-related events (SREs) using data from a phase III, randomized study of zoledronic acid in patients with bone metastases from BC. The trial evaluated the number and timing of SREs (pathologic fracture, palliative radiotherapy to bone, surgery to bone to treat or prevent a fracture, and spinal cord compression) and assessed variables for prognostic significance in univariate and multivariate Cox-regression analyses. Continuous variables were categorized with predefined cutpoints. All associations with P < 0.05 were considered significant. A total of 444 zoledronic acid-treated patients with assessments of biochemical markers of bone metabolism and complete baseline variable data were included. Significant baseline prognostic factors for occurrence of a first SRE by multivariate analyses included age, pain score, prior history of an SRE, predominant lesion type, elevated bone-specific alkaline phosphatase, and lactate dehydrogenase. Prior fracture was found to be prognostic in a reduced multivariate analysis of time to first fracture, but not for time to first palliative radiotherapy. In conclusion, this model identified several prognostic factors that may be useful in routine clinical care. Validation of these factors in a separate dataset and generation of a prognostic risk score are recommended next steps.

Abstract
Although it may be argued that single fraction (SF) radiotherapy (RT) should be regarded as the standard palliative treatment for pain due to uncomplicated bone metastases, its widespread clinical use is still underexploited. In this chapter, the authors discuss a number of surveys investigating doctors and patients' preferences for palliative RT schedules, discuss the possible reasons for this phenomenon, and suggest potential strategies to increase the use of SF.

Abstract
The objective of this study was to examine the agreement between health care professionals' (HCPs) and patients' evaluation of health-related quality of life (HRQOL) issues for cancer patients with bone metastases. A total of 413 patients and 152 HCPs were interviewed across five centres worldwide. Mean scores were almost always higher for HCPs than for patients. Patients and HCPs agreed that four issues affect HRQOL of bone metastases patients profoundly: 'long-term (chronic) pain', 'difficulty in carrying out usual daily tasks', 'able to perform self-care' and 'able to perform role functioning'. A substantial difference was found with respect to the perceived importance of psychosocial and somatic issues. Patients emphasised psychosocial issues with a particular focus on 'worry' about loss of mobility, dependence on others and disease progression, HCPs however rated 'symptom' issues as more important, specifically those related to 'pain'. In conclusion, patients and HCPs agreed that pain and physical/role functioning are important to the HRQOL of cancer patients with bone metastases, but patients also emphasized the importance of psychosocial issues to HRQOL. This information has been an important component in the development of a health-related quality of life questionnaire for patients with bone metastases (EORTC QLQ-BM 22).

Abstract
Quality of life (QOL) has become an important consideration in the care of patients with bone metastases as prevalence, incidence and patient survival are on the rise. As a result, more interventional studies now measure patient’s QOL as a meaningful endpoint. However, well-developed bone metastases specific quality of life instruments are lacking. A literature review was conducted to better understand the nature of QOL instruments used in bone metastases trials. A total of 47 articles evaluating QOL in patients with bone metastases were identified. Twenty-five different instruments were used to evaluate QOL with study-designed questionnaires and the EORTC QLQ-C30 being most commonly employed. Many studies used more than one scale or instrument to measure QOL. This makes it difficult to compare QOL in bone metastases patients across studies and come to any formal conclusions. Therefore, this review demonstrates the need to develop a bone module that can be used across countries in future clinical trials.

Did the pattern of practice in the prescription of palliative radiotherapy for the treatment of uncomplicated bone metastases change between 1999 and 2005 at the rapid response radiotherapy program? Clin Oncol (R Coll Radiol) 2008; 20:327-36. [PMID: 18276125 PMCID: PMC7126631 DOI: 10.1016/j.clon.2008.01.002] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2007] [Revised: 12/19/2007] [Accepted: 12/20/2007] [Indexed: 01/15/2023]
Abstract
AIMS Since 1999, randomised clinical trials and meta-analyses have reported equal efficacy of pain relief from single- and multiple-fraction radiotherapy for bone metastases. A number of factors, including limited radiotherapy resources, waiting times, and patient convenience, suggest single fraction to be the treatment of choice for patients. However, international patterns of practice indicate that multiple fractions are still commonly used. This study examined whether dose-fractionation schemes used for the treatment of bone metastases at the Rapid Response Radiotherapy Program (RRRP) at the Odette Cancer Centre have changed since 1999. MATERIALS AND METHODS A retrospective review of the prospective RRRP database and hospital records were conducted for all patients treated with palliative radiotherapy for uncomplicated bone metastases at the RRRP in 1999 (or baseline), 2001, 2004 and from 1 January to 31 July 2005. Data were collected on patient demographics and clinical characteristics. RESULTS Of the 693 patients, 65 and 35% were prescribed single fraction (predominantly single 8 Gy) and multiple fractions (predominantly 20 Gy/five fractions), respectively. The administration of single treatments generally increased over time, from 51% in 1999 to 66% in 2005 (P=0.0001). On the basis of multiple logistic regression analyses, patients were more likely to be prescribed single-fraction radiotherapy if they had prostate cancer, had a poorer performance status, were treated to the limbs, hips, shoulders, pelvis, ribs, scapula, sternum, or clavicle (compared with the spine), were treated by a radiation oncologist who had been trained in earlier years, and who were treated after 1999. CONCLUSIONS Between 1999 and 2005, the use of single-fraction radiotherapy increased, corresponding to publications showing equal efficacy of pain relief between single and multiple fractions in the management of uncomplicated bone metastases. However, about a third of patients still received multiple fractions.

Abstract
INTRODUCTION Since the 1980s, randomized clinical trials showed that single fraction radiotherapy (RT) provided equal pain relief as multiple fractions of RT in the treatment of bone metastases. MATERIALS AND METHODS Using Medline, a literature search was conducted on patterns of practice among radiation oncologists and patients' preferences of dose fractionations for the treatment of bone metastases. RESULTS AND DISCUSSION Fifteen studies on international patterns of practice published between 1966 and May 2006 were identified. Surveys of Canadian radiation oncologists indicated approximately 85% preferred multiple fractions, most often as 20 Gray in five fractions (20 Gy/5). Surveys in the United States indicated that 30 Gy/10 was most commonly used, and 90-100% of these oncologists preferred multiple over single fraction RT. Multiple fractions were most commonly used in the United Kingdom, Western Europe, Australia and New Zealand, and India; however, more radiation oncologists in these countries would prescribe a single fraction than in North America. Three studies investigated patients' preferences of dose fractionations. In the Australian study, most patients favored single fraction RT as long as long-term outcomes were not compromised. Durability of pain relief was considered more important than short-term convenience factors. In the Singapore study, 85% of patients would choose extended courses of RT (24 Gy/6) compared to a single 8 Gy. In the Canadian study, most patients (76%) would choose a single 8 Gy over 20 Gy/5 of palliative RT due to greater convenience. CONCLUSION Despite strong evidence supporting the use of single fraction RT, current practices and preferences favor multiple fractions for the treatment of bone metastases. This has significant implications for the overall quality of life, RT department workload, costs to healthcare systems, and patient convenience.

Patients with a favourable prognosis are equally palliated with single and multiple fraction radiotherapy: results on survival in the Dutch Bone Metastasis Study. Radiother Oncol 2006; 78:245-53. [PMID: 16545474 DOI: 10.1016/j.radonc.2006.02.007] [Citation(s) in RCA: 117] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2005] [Revised: 02/08/2006] [Accepted: 02/23/2006] [Indexed: 01/06/2023]
Abstract
BACKGROUND AND PURPOSE In the prospectively, randomized Dutch Bone Metastasis Study on the effect of a single fraction of 8 Gy versus 24 Gy in six fractions on painful bone metastases, 28% of the patients survived for more than 1 year. Purpose of the present study was to analyze the palliative effect of radiotherapy in long-term surviving patients, and to identify prognostic factors for survival. MATERIAL AND METHODS Response rates were compared in all patients surviving>52 weeks. The Cox proportional hazards model stratified by primary tumour was used for multivariate (MV) analyses of prognostic factors for survival. RESULTS In 320 patients surviving>52 weeks, responses were 87% after 8 Gy and 85% after 24 Gy (P=0.54). Duration of response and progression rates were similar. For all primary tumours, prognostic factors for survival were a good Karnofsky Performance Score, no visceral metastases, and non-opioid analgesics intake (all factors, MV P<0.001). CONCLUSIONS Single fraction radiotherapy should be the standard dose schedule for all patients with painful bone metastases, including patients with an expected favourable survival. General prognosticators as the Karnofsky Performance Score and metastatic tumour load are useful in predicting survival.

Abstract
Symptom control has become increasingly recognized as an important goal in patient care. In this article, advances in symptom assessment, and various definitions of symptom improvement are reviewed. Theoretical concepts underlying symptom control and clinically significant change are presented, as well as the role of symptom control as an endpoint in clinical trials. Symptom control is then surveyed in two broad categories for selected symptoms. The first area is therapy related symptoms, secondary to chemotherapy, radiation, hormonal therapy, and surgery. Symptoms reviewed include chemotherapy related mucositis, emesis, fatigue; hot flashes; and radiation related dermatitis, xerostomia, and mucositis. The second area is palliative oncologic approaches to disease-related symptoms. Results in palliative chemotherapy, palliative radiation therapy, cancer pain, and lack of appetite are summarized. Areas requiring further research are noted. Findings are presented in both a clinical and research context to help guide the reader with interpreting symptom control studies.

Abstract
Palliative radiotherapy is effective in the treatment of bone metastases but is under-utilized, possibly because it is perceived to be expensive. We performed a cost-utility analysis of palliative radiotherapy for bone metastases, evaluating both the actual cost of radiotherapy as well as its impact on quality of life by adjusting for the variation in response to treatment. Hospital records between July 1991 and July 1996 were reviewed to ascertain the number of patients treated with palliative radiotherapy for bone metastases, the average number of fields of radiation delivered to each patient and the average duration of survival. Partial and complete response rates to palliative radiotherapy were obtained from a review of all published randomized controlled trials of radiation treatment of bone metastases. Utility values were assigned to the response rates, and an overall adjusted response rate to radiotherapy was derived. The cost of delivering a field of radiation was calculated. The total cost was divided by the total number of response months to give a utility-adjusted cost per month of palliative radiotherapy. The utility-adjusted cost per month of palliative radiotherapy of bone metastases was found to be AUS dollars 100 per month or AUS dollars 1200 per utility-adjusted life-year. This study demonstrates that, contrary to popular perception, palliative radiotherapy is a cost-effective treatment modality for bone metastases.
