Cancers affecting bone are difficult to treat and are
a significant impact on a patient’s quality of
life. The cells of the bone are surrounded in an environment
(marrow or matrix) which may support tumor cells, or
be attractive to the spreading tumor cells (metastases).
The cells include osteoblasts (bone forming); osteoclasts
(bone removing); stem cells with the potential to form
these and other cells, and also supportive cells.
If bones are affected by cancer, the normal architecture is replaced
by tumor tissue. This process may be slow or rapid, and the ensuing weakness
causes significant pain and fragility. The associated disease is very
disabling and leads to a greatly reduced quality of life. All these cells
are being researched to better understand their function in normal and
disease states. This information will
be used to develop
drugs to arrest tumor growth and improve bone strength. [back...]
