Skeletal metastases from breast cancer: Role of positron emission tomography and bone scintigraphy in the evaluation of bone involvement in metastatic pheochromocytoma and paraganglioma: Is the carcinoembryonic antigen test a valid predictor of response to medical therapy in disseminated breast cancer? Estrogen and progesterone receptors: Our literature review disclosed substantial variations in estimates of the sensitivity and specificity of each imaging modality Table 2 , in large part because the basis for measuring sensitivity and specificity differed from study to study.

Imaging Bone Metastases in Breast Cancer: Staging and Response Assessment
Metastases from kidney, thyroid, and lung malignancies are predominantly osteolytic, while osteoblastic lesions are usually seen in prostate cancer and breast cancer. Bone metastases are common in patients with advanced breast cancer. The function of the vertebral veins and their role in the spread of metastases. Osseous metastases of breast cancer. Progressive disease, conversely, is visualized as increased uptake or the appearance of new lesions. Mixed; some lesions persist while others progress, or new lesions appear. A multicenter randomized controlled trial.

Imaging in Bone Metastases
XR can visualize response in terms of a known lytic lesion becoming sclerotic or a sclerotic lesion becoming smaller or fading. Tcm bone scintiscan findings are nonspecific in determining the cause of increased uptake, particularly in solitary lesions. In this review, we discuss the pros and cons of six imaging modalities—SS, XR, computed tomography CT , magnetic resonance imaging MRI , positron emission tomography PET , and single photon emission computed tomography SPECT —with regard to how well they detect bone metastases and the response of such metastases to treatments such as chemotherapy or endocrine therapy. Many of the tests used to find bone metastases may have also been done when you were first diagnosed with cancer. Mechanisms of bone metastasis. Although breast cancer can spread to any bone, the most common sites are the ribs, spine, pelvis, and long bones in the arms and legs. Systemic medications include chemotherapy, hormonal therapy, targeted therapies, and bone-strengthening medication. Bone scan CT computed tomography scan MRI magnetic resonance imaging PET positron emission tomography scan Many of the tests used to find bone metastases may have also been done when you were first diagnosed with cancer.
Description:Staging of cancer of the breast as a guide to therapy. Comparative sensitivity of CT scans, radiographs and radionuclide bone scans in detecting metastatic calvarial lesions. Other imaging modalities such as XR, CT, or MRI should be used to characterize such lesions, including any soft tissue components, and to assess the risk of fracture. Thank you for updating your details. Although breast cancer can spread to any bone, the most common sites are the ribs, spine, pelvis, and long bones in the arms and legs. Compared with other imaging techniques, radiography is relatively insensitive in detecting bone metastases, especially subtle lesions. Partial decrease in size of lytic lesions, recalcification of lytic lesions, or decreased density of blastic lesions for at least 4 weeks. Although BS has served well for several decades, more recent advances in imaging have enabled several techniques to be used for staging of the skeleton with higher sensitivity and specificity.
