title: [Encounter of cancer cells with bone. Histological examination of bone metastasis].
abstract: Management of the cancer bone metastasis is important clinical problem. The mechanism (s) of bone metastasis has been studied mainly by animal models and in vitro system. There might be discrepancy between model systems and in vivo human clinical materials. But there is surprisingly rare study of histological examination of human skeletal metastasis, since it is hard to obtain human materials without modification by chemotherapy or irradiation. There are many surgical materials suitable for this examination in our hospital and we have been examined histological features of them. Stromal cells between metastatic cancer cells and OCs (osteoclasts) and÷or OBs (osteoblasts) might play a role in bone metastasis, since these cells are frequently accompanied with OCs÷OBs. We called these stromal cells as "fibroblast-like cells" and examined their nature and roles in bone metastasis. We hope these fibroblast-like cells might become the target of anti bone metastasis therapy, same as osteoclasts targeted by bisphosphonates.
