Since1986 we have monitored the actual diagnosis of all cases referred to our Unit with the diagnosis of ‘possible primary malignant bone tumour’. We have excluded all patients referred with a known diagnosis of either a benign condition or known to have bone metastases. In most cases the suspected diagnosis was based on X-rays alone, sometimes supported by further imaging.

Method

Retrospective review of a prospective database that was started in 1986 identifying the actual diagnosis.

Results

There were 5922 patients with a confirmed diagnosis over the 23 year time period of this study. 2205 (37%) were found to have a primary malignant bone sarcoma and 1309 (22%) had a benign bone tumour. 992 patients had a general orthopaedic condition (e.g. geode or a vascular necrosis) whilst 303 (5%) had a haematological malignancy and 289 (4.9%) infection. 533 patients (9%) had metastases. There was a similar pattern of frequency of all diagnoses except for metastatic disease and haematologic malignancy at different ages. The incidence of metastases increased from the age of 35 onwards
