Childhood cancers are rare because cancer is primarily age-related. The American Cancer Society says that out of 1370000 new cancer in the United States this year 0.9200 and occur in children age 14 or younger, and 313 of those will be rhabdomyosarcomas.
The American Cancer Society says 78 percent of children with cancer survive at least five years. But Keller says five-year survival is a dismal 5 percent to 30 percent - depending on the study group - among children with alveolar rhabdomyosarcoma, the most severe form of the disease. (Another form, embryonic rhabdomyosarcoma, and more responsive to treatment).
Capecchi says the cancer causes tumors in various muscles throughout the body, primarily in the arms, legs and shoulders, but also in the back and torso, neck and even the tongue.

Scientists already know that 85 to 90 percent of children with alveolar rhabdomyosarcoma have an oncogene - cancer-causing gene - named Pax3: Fkhr.
Is known as the «gene fusion" because when the forms of two chromosomes to break into all the pieces and then fuse or combine. Includes this gene fusion piece of Pax3 - which plays a role in the formation of the muscles and nervous system and head - and a piece of Forkhead Fkhr, a gene that acts as a suppressor for control of tumor cell division, which runs amok in cancer. Researchers believe Pax3: Fkhr cause cancer by triggering inappropriate muscle development.
In the first study, the researchers also discussed how the Pax3: Fkhr fusion gene affected the development of mouse embryo, and muscle formation in the embryo, and muscle growth that occurs after the birth of mouse stem cells and satellite raises new muscle cells.
