Introduction: Involvement of the skeleton can cause an excruciating pain in two-thirds of terminal patients with a history of malignancy. Due to several limitations of other therapies, such as analgesics, bisphosphonates, chemotherapy, hormonal therapy and external beam radiotherapy; bone-seeking radiopharmaceuticals have an important role in palliation of pain from bone metastases. Although th...
Skeletal metastases are frequent complications of many cancers, causing bone (fractures, pain, disability) that negatively affect the patient’s quality life. Here, we first discuss burden skeletal in cancer metastasis. We then describe pathophysiology Bone metastasis is a multistage process: long before development clinically detectable metastases, circulating tumor cells settle and enter dorma...
objective(s): bonenavi, a computer-aided diagnostic system, is used in bone scintigraphy. this system provides the artificial neural network (ann) and bone scan index (bsi) values. ann is associated with the possibility of bone metastasis, while bsi is related to the amount of bone metastasis. the degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. therefore, t...
treatment of bone metastases comprises over 10% of the workload of a radiation-oncology center. bone metastases produce severe pain and immobility, necessitate narcotic use, and reduce the quality of life. a good palliative treatment must be complete, free from side effects and fast; thus we decided to evaluate strontium-89 (89sr) effectivity for palliation of breast and prostate cancer bone me...
Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC) stage T4N2M1b, with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabol...
OBJECTIVES This study aimed to develop a scoring system to predict the survival time of patients with bone metastases after radiation therapy (RT). The scoring system can guide physicians to a better selection of appropriate treatment regimens. MATERIALS AND METHODS The medical records of 125 patients with bone metastases treated with RT between January 2007 and September 2010 were reviewed r...
Thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. Multiple sites of Thallium uptake correlated with the findings on serial bone scans and radiographs. Bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.
Bone scintigraphies are widely applied for detecting bone metastases. The aim of this study was to investigate distribution features of bone metastases in pulmonary and prostate cancers. Bone scintigraphies were performed in 460 patients with pulmonary cancer and 144 patients with prostate cancer. Patients were divided into three groups according to the total number of bone metastases: few bone...
Objective(s): Recently, bone-avid radiopharmaceuticals have been shown to have potential benefits for the treatment of widespread bone metastases. Although 177Lutriethylene tetramine hexa methylene phosphonic acid (abbreviated as 177Lu- TTHMP), as an agent for bone pain palliation, has been evaluated in previous studies, there are large discrepancies between the obtained results. In this study,...
