WITHDRAWN: Radioisotopes for metastatic bone pain.
This is an update of the review published in Issue 4, 2003. Bone metastasis cause severe pain as well as pathological fractures, hypercalcaemia and spinal cord compression. Treatment strategies currently available to relieve pain from bone metastases include analgesia, radiotherapy, surgery, chemotherapy, hormone therapy, radioisotopes and bisphosphonates.. To determine efficacy and safety of radioisotopes in patients with bone metastases to improve metastatic pain, decrease number of complications due to bone metastases and improve patient survival.. We sought randomised controlled trials (RCTs) in MEDLINE, EMBASE, CENTRAL, and the PaPaS Trials Register up to October 2010.. Studies selected had metastatic bone pain as a major outcome after treatment with a radioisotope, compared with placebo or another radioisotope.. We assessed the risk of bias of included studies by their sequence generation, allocation concealment, blinding of study participants, researchers and outcome assessors, and incomplete outcome data. Two review authors extracted data. We performed statistical analysis as an "available case" analysis, and calculated global estimates of effect using a random-effects model. We also performed an intention-to-treat (ITT) sensitivity analysis.. This update includes 15 studies (1146 analyzed participants): four (325 participants) already included and 11 new (821 participants). Only three studies had a low risk of bias. We observed a small benefit of radioisotopes for complete relief (risk ratio (RR) 2.10, 95% CI 1.32 to 3.35; Number needed to treat to benefit (NNT) = 5) and complete/partial relief (RR 1.72, 95% CI 1.13 to 2.63; NNT = 4) in the short and medium term (eight studies, 499 participants). There is no conclusive evidence to demonstrate that radioisotopes modify the use of analgesia with respect to placebo. Leucocytopenia and thrombocytopenia are secondary effects significantly associated with the administration of radioisotopes (RR 5.03; 95% CI 1.35 to 18.70; Number needed to treat to harm (NNH) = 13). Pain flares were not higher in the radioisotopes group (RR 0.74; 95% CI 0.27 to 2.06). There are scarce data of moderate quality when comparing Strontium-89 (.

Pain flares were not higher in the radioisotopes group (RR 0.74; 95% CI 0.27 to 2.06). There are scarce data of moderate quality when comparing Strontium-89 ((89)Sr) with Samarium-153 ((153)Sm), Rhenium-186 ((186)Re) and Phosphorus-32 ((32)P). We observed no significant differences between treatments. Similarly, we observed no differences when we compared different doses of (153)Sm (0.5 versus 1.0 mCi).. This update adds new evidence on efficacy of radioisotopes versus placebo, (89)Sr compared with other radioisotopes, and dose-comparisons of (153)Sm and (188)Re. There is some evidence indicating that radioisotopes may provide complete reduction in pain over one to six months with no increase in analgesic use, but severe adverse effects (leucocytopenia and thrombocytopenia) are frequent.

Bone metastases and tumor-induced hypercalcemia.
Tumor-induced hypercalcemia and tumor-induced osteolysis are essentially due to a marked increase in osteoclast-mediated bone resorption, although the kidneys play an important contributory role in the genesis of tumor-induced hypercalcemia. Parathyroid hormone-like protein plays an essential role in tumor-induced hypercalcemia, and maybe in tumor-induced osteolysis, but other factors could also be responsible for the osteoclast activation secondary to the neoplastic infiltration of the skeleton. Treatment of tumor-induced hypercalcemia essentially consists of volume repletion and administration of potent anti-osteolytic drugs. The bisphosphonate pamidronate is particularly useful for that matter and a dose of 1.0 to 1.5 mg/kg can normalize serum calcium in about 90% of hypercalcemic cancer patients. The apparently low response rate of bone metastases to systemic antineoplastic therapy seems to essentially reflect the relative insensitivity of our current methods for assessing response in tumor-induced osteolysis. Newly developed biochemical markers of bone turnover could be particularly useful for that matter. Bisphosphonates are the most potent of the available inhibitors of osteoclast activity. Prolonged administration of oral pamidronate could reduce by almost one half the complications of tumor-induced osteolysis, and repeated bisphosphonate infusions could induce a dramatic relief of bone pain in one third and a sclerosis of lytic lesions in one fourth of the cases. These data must, however, be confirmed in randomized, blinded trials and many questions remain unanswered concerning the optimal therapeutic schemes. Medical therapy of tumor-induced osteolysis by noncytotoxic means has nevertheless become a reality.

Hypocalcemia associated with strontium-89 administration in a patient with diffuse bone metastases from neuroendocrine carcinoma.
Metastatic bone disease is often associated with severe pain in cancer patients, and has become an increasingly important quality-of-life issue. Radionuclides, such as strontium-89 (Sr-89), have provided effective palliation of metastatic bone pain. Although strontium follows the biochemical pathways of calcium in the body, changes in calcium homeostasis related to Sr-89 therapy have rarely been reported. We present a case of a 32-year-old male with poorly differentiated neuroendocrine carcinoma and extensive skeleton metastases who developed profound hypocalcemia after Sr-89 administration.

Incidence and sites of bone lesions detected by 99mTc-polyphosphate scans in patients with tumors.
The value of bone scanning with 99mTc-polyphosphate was assessed in 186 patients with various types of tumors. The sensitivity of this technique was greater than that of metastatic roentgenographic series and the reported results of 85-Sr-bone scans, in the detection of osseous involvement by tumors. Three cases with normal bone scans and abnormal roentgenographic studies illustrated the necessity and complementary value of comparing bone scan findings with radiographic studies. Patients with carcinoma of the breast, lung, or prostate displayed characteristic patterns of bone involvement by their tumors. The importance of clinical information, including bone symptoms, antecedent bone disease, and serum calcium and alkaline phosphatase, was stressed in the detection and interpretation of bone scan abnormalities.
