This study shows that 0.8 per cent. of all orthopaedic patients seen at the Campbell Clinic were suffering from some sort of bone tumor, benign or malignant. More tumors were malignant than benign.
Comparison of this study with one made nine years earlier bears out the warning given by Hamilton, that favorable results after five years in cases of Ewing's tumor do not assure freedom from metastasis. On the other hand, five-year favorable results in Other malignant bone tumors are much more indicative of a permanent cure.
The results in malignant bone tumors are almost invariably bad. However, in Ewing's tumor, osteogenic sarcoma, chondromyxosarcoma, and fibrosarcoma, cures of over five-years duration have been recorded. The most logical treatment is early amputation, followed by irradiation.
