Strontium 89 in the treatment of pain due to diffuse osseous metastases: a university hospital experience.
More than two-thirds of the patients with osseous metastases experience debilitating bone pain, requiring some form of pain relief. Analgesics are limited in their efficacy. Palliative application of hemi-body external beam radiation therapy in the treatment of multiple osseous metastases also is limited due to toxicity associated with large treatment ports. Intravenous injections of bone seeking radioisotopes are effective in the palliation of pain with fewer side effects. Forty-one patients with multiple osseous metastases due to prostate and breast cancer were treated with strontium chloride 89 (89Sr) at the department of radiation oncology, in a university hospital. A retrospective analysis of these patients indicated that all subjects had severe pain that diminished their quality of life. Most of these patients had multiple co-morbid factors. Many were on opioids leading to adverse effects such as nausea, constipation, and drowsiness that required additional medication. Objective findings and evaluation of the responses were not always available for all patients. Following treatmentwith 89Sr, over two-thirds of the patients responded favorably and required lower doses of opioids.
