Cade's 1955 series of 133 histologically confirmed osteosarcoma patients asks whether primary radiotherapy — with amputation reserved for patients who do not develop early metastases — is a rational alternative to the then-universal practice of immediate amputation. The study spans 30 years at Westminster Hospital across two eras: teleradium (1925–1950, n=84) and supervoltage X-rays at 2 MeV (1951 onward, n=49). It does not propose a cure — it proposes a humane, evidence-based framework for a disease where cure was rarely achievable.
In 1955, the standard of care for osteosarcoma was immediate amputation — performed reflexively despite overwhelming evidence that most patients died of pulmonary metastases within two years no matter what was done locally.
Cade's paper is the reason we no longer treat osteosarcoma as a primarily surgical disease. By demonstrating that early amputation does not prevent metastatic death, it forced a conceptual shift: the fight against osteosarcoma is systemic, not local. When you see a young patient with a destructive metaphyseal lesion, this paper is the historical anchor for why your first call is to oncology, not the OR.
The practical legacy of Cade's staged approach. Irradiate, observe for metastases, then operate on those who remain disease-free. Is directly visible in modern neoadjuvant chemotherapy protocols, which use the same logic: treat systemically first, then reassess for local control.
For cases where resection is anatomically impossible (sacrum, spine, skull base), this paper remains the historical justification for palliative radiotherapy as the primary modality. A fact still tested on boards and still clinically relevant.
