An 8-YEAR analysis of bone tumours in a Caribbean island

摘要

Background An epidemiologic analysis of bone tumours in Trinidad & Tobago. Methods A retrospective analysis of primary and secondary bone tumours, site of origin and demographic data was conducted. Results 63 bone tumours were analysed and included 27 primary benign (43%), 12 primary malignant (19%), 19 metastatic (30%) and 5 by contiguous spread (8%). The most common malignant primary tumour was the osteosarcoma (n?=?7), originating from the femur in mostly males in the 11–20 age group. There was 1 chondrosarcoma, 2 fibrosarcomas and 2 plasmacytomas. Benign tumours consisted of 8 osteochondromas, 2 osteomas, 3 giant cell tumours, 3 bone cysts and 11 cases of fibrous dysplasia. Conclusion Bone tumours are rare with a low incidence of 1.125 per 100,000 population annually and malignant tumours being even rarer at an incidence of 0.18 per 100,000 population annually. There is need for better documentation and data registries in Trinidad and Tobago. Highlights ? The incidence of primary bone tumours is low in the Caribbean. ? Osteosarcoma is the most common primary bone tumour and present in males 11–20 years old.
