A number of cancers predominantly metastasize to bone, due to its complex microenvironment and multiple types of constitutive cells. Prostate cancer especially has been shown to localize preferentially to bones with higher marrow cellularity. Using an experimental prostate cancer metastasis model, we investigated the effects of cyclophosphamide, a bone marrow-suppressive chemotherapeutic drug, ...
Metastasis may arise years after removal of a primary tumor. The mechanisms allowing latent disseminated cancer cells to survive are unknown. We report that a gene expression signature of Src activation is associated with late-onset bone metastasis in breast cancer. This link is independent of hormone receptor status or breast cancer subtype. In breast cancer cells, Src is dispensable for homin...
Metastasis proceeds through interaction between cancer cells and resident cells such as leukocytes and fibroblasts. An i.v. injection of a mouse renal cell carcinoma, Renca, into wild-type mice resulted in multiple metastasis foci in lungs and was associated with intratumoral accumulation of macrophages, granulocytes, and fibroblasts. A chemokine, CCL3, was detected in infiltrating cells and, t...
Prostate cancer is the most common cancer in men in Western countries, with a high incidence of bone metastasis. The bony metastasis is incurable and contributes significantly to disease-specific morbidity and mortality. The molecular and cellular mechanisms leading to the development of bone metastasis in prostate cancer remain unclear, but are currently under intensive investigation. In this ...
Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic cytokine which controls the differentiation and growth of hematopoietic cells in the bone marrow. We report a severe aplastic anemia (SAA) patient with false-negative 99mTc sodium phytate bone marrow imaging findings under concurrent G-CSF therapy. The first bone marrow imaging showed a normal bone marrow activity. However, the bo...
Neuroblastoma, the most common extracranial pediatric solid tumor, is responsible for 15% of all childhood cancer deaths. Patients frequently present at diagnosis with metastatic disease, particularly to the bone marrow. Advances in therapy and understanding of the metastatic process have been limited due, in part, to the lack of animal models harboring bonemarrow disease. The widely used trans...
A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum....

Studies have shown the prognostic significance of disseminated tumor cells (DTC) in bone marrow of patients with colorectal cancer. However, the molecular characteristics of DTCs, including their miRNA expression profiles, remain mostly unknown. In this study, we analyzed the miRNA expression of DTCs in bone marrow. EpCAM(+) bone marrow cells were collected using immunomagnetic beads after excl...
PURPOSE Breast cancers in the early phase frequently undergo distant metastasis and survival of patients is greatly dependent on distant metastasis. The occurrence of micrometastasis has been suggested to relate with prognostic features of breast cancer, such as lymph node metastasis and the presence of vascular invasion. The aim of this study was to examine the presence of keratin-19 mRNA of e...
