BACKGROUND The natural history of castration-resistant nonmetastatic prostate cancer is poorly defined. METHODS The authors used data from 331 subjects in the placebo group of a randomized controlled trial to evaluate the relations of disease and host characteristics with time to first bone metastases in men with prostate cancer, rising prostate-specific antigen (PSA) despite androgen depriva...

PURPOSE Bone is the most frequent site of metastasis among breast cancer patients. We investigated prognostic factors affecting survival following bone-only metastasis in breast cancer patients. MATERIALS AND METHODS The medical records of breast cancer patients who were treated and followed at Gangnam Severance Hospital retrospectively reviewed to identify patients with bone-only metastasis....

Breast cancer (BC) is one of the most common cancers in women, and it can often metastasize to the bone. The mechanism of BC bone metastasis remains unclear and requires in-depth investigation. In a previous study, we found the expression of matrix metalloproteinase 2 (MMP2) to be significantly more pronounced at metastatic bone sites than at orthotopic sites. MicroRNA expression profiling show...

Adenoid cystic carcinoma (AdCC) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1). The most commonly-affected sites of...

Abstract Prostate cancer is one of the most common cancers affecting men. Bone scan part staging modality commonly used to evaluate bone metastasis. A with diffused increased skeletal tracer uptake relative soft tissue, combined faint renal activity known as a superscan. However, primary concern are false negatives associated scans, where diffuse metastasis indistinguishable on superscans. In t...

Cancer patients with spinal metastases are a diagnostic and treatment challenge for the clinician. This challenge must be addressed through a multidisciplinary, multimodal, and individualized management. The presence of tumor cells in bone metastases results in homeostatic disruption between bone formation and remodeling. Bone destruction is a late event in the formation of lytic bone metastasi...

Bone metastasis is very frequent in prostate cancer. Diagnosis is generally easy to make with scintigraphy and it can be confirmed by TDM and RMI. Before metastasis become symptomatic, treatment includes physical and nutritional advice with drugs to prevent bone events (pain, fracture, compression and hypercalcemia). Associated with a effective hormonal treatment, radiotherapy, surgery and anal...

Osteolytic bone metastasis frequently occurs in the later stages of breast, lung, and several other cancers. Osteoclasts, the only cells that resorb bone, are hijacked by tumor cells, which break down bone remodeling systems. As a result, osteolysis occurs and may cause patients to suffer bone fractures, pain, and hypercalcemia. It is important to understand the mechanism of bone metastasis to ...
