Abstract
Ten cases of irradiation induced sarcoma of bone which fulfilled Cahan's criteria were seen in a twenty year period at the Princess Margaret Hospital. The overall incidence of this complication is 0.035% of all irradiated five year survivors. Combining our data with three other large series presented in the literature, a dose complication curve could be deduced. On the basis of the human and animal data reviewed, it was concluded that the risk of radiation induced sarcoma is so low in the dose range of modern radiotherapeutic practise that it does not represent a contraindication to the use of radiation therapy.
