简要总结
The purpose of this study is to evaluate cost-utility analysis in order to provide recommendations to French decision-makers between vertebroplasty and radiation therapy in Bone spine metastases. Indeed, radiation therapy is often advocated a systematic way. The object of this study would be to expand the use of vertebroplasty.
Moreover, this study assess to the strategy impact on the pain control reduction and functional preservation. In fact, analgesic effect is achieved differently depending on the procedure used.Eligible patients will be recruited and registered consecutively. Patients will be randomly,
This is a health-economic multicenter, prospective, randomized with stratification according to number of vertebrae to treat (1-3 vertebrae vs 4-6 vertebrae) and center :
- Arm A: Percutaneous vertebroplasty
- Arm B: External radiotherapy
This is an open-label study. The expected total study period is 2.5 years (enrolment: 2 years, patient follow-up: 6 months). A total number of 304 patients with spine metastases will be recruited (152 patients/arm).
详细描述
Bone is the most common site for metastasis. In breast and prostate cancers, 70% of patients dying of their cancer have evidence of metastatic bone disease [Coleman, 2006]. Depending on their localization, bone metastases can have debilitating consequences resulting in considerable morbidity and complex demands on health care resources. Bone spine metastases are the most frequent site observed in patients with cancer of the lung, prostate, breast and hemopoetic organs. The occurrence of spinal metastases in patients with advanced cancer can cause significant morbidity, with pain and/or neurological deficit adversely affecting the patients' quality of life.
Interventional radiology takes a large place in the treatment of bone metastases. Currently, vertebroplasty appears as the most satisfactory technique for stabilization of spine metastases offering a significant improvement of the quality of life. The analgesic effect is achieved very rapidly, i.e. usually within 24 hours post-procedure. Based on several publications, around 90% of patients reported rapid pain relief following vertebroplasty with 60 to 70% of complete pain relief [Mendel, 2009].
Radiotherapy also plays a very important role in the palliative treatment of the metastatic bone. Radiotherapy is effective and well tolerated. A reduction of the pain is noticed for 70 to 80 % of the patients and begins one or two weeks after the treatment. In all, the radiotherapy increases the quality of life of the patients and can reduce the intake of analgesics [Lutz, 2011].
In a lot of cases, vertebroplasty or radiotherapy can both be performed for a same painful patient (the National Institute for Health and Clinical Excellence (NICE) approved the use of vertebroplasty for patients with spinal metastases in November 2008). Radiotherapy remains the gold-standard treatment. However, vertebroplasty could be less costly and more effective compare to radiotherapy. In fact, the superiority of vertebroplasty has been demonstrated at least in the acute post-therapeutic period with (i) more rapid autonomy recovery, (ii) reduction of antalgic intakes, and potentially less side-effects.
