The Cade Regime for Osteosarcoma

Sir Stanford Cade was one of the pioneers of radiotherapy and worked at the Westminster Hospital between 1924 and 1960. Amongst his extraordinary output he published a thoughtful paper on the treatment of osteogenic sarcoma in the prechemotherapy era (1).  He reasoned that early amputation had no impact on survival in osteosarcoma, and therefore that early metastasis was the norm. Furthermore he argued that to amputate the limbs of patients with such a poor prognosis was unreasonable and mutilating. The Cade regime therefore involved high dose radiotherapy to the primary tumour site, followed by secondary amputation if the patient survived long enough. He was able to demonstrate clinical, radiological and pathological responses to radiotherapy in this relatively radioresistant tumour.  His description defined treatment for osteosarcoma in the prechemotherapy era.
