Abstract

Aim: To determine the epidemiological, diagnosis and treatment of secondary bone cancer at the National Hospital University Hubert Koutoukou Maga of Cotonou. Patients and Method: It was a retrospective descriptive cross-sectional study carried out from January 1999 to December 2013 on the records of patients treated in the rheumatology department. The selected files had radiological images of tumor appearance objectified by two radiologists. The diagnosis of secondary bone cancer was confirmed after a bone biopsy or the discovery of a primitive tumor site. Patients with hematologic malignancy and incomplete or insufficiently explored records were excluded. Results: Among 10,292 patients followed in the service, 51 (0.5%) had documented bone metastasis. The sex ratio was 1.83. The mean age of patients was 54 ± 9 [26-85] years, with 53% of those over 60 years old. Secondary cancers were on the spine (74.5%), pelvis (35.3%) and the long bones (39.2%). The primary cancer most frequently found was that of the prostate and breast (45.1% and 27.6%, respectively) followed by genital and digestive cancers (9.8% and 7.8%, respectively). Treatment was dominated by hormone therapy (83%) bisphosphonates (70.5%) and chemotherapy (57%). Conclusion: The profile of bone cancer in Benin hospital is very diverse and dominated by the types and osteolytic ostéocondensant. Primary cancers were dominated by the prostate and breast. Bisphosphonates took an important place in the treatment of the disease.
