摘要

Objectives: The aim of this study was to describe the diagnostic and etiologicalaspects of bone metastases in the Rheumatology Department of Cocody’sUniversity Teaching Hospital (UTH). Methodology: This was a descriptive,11-year retrospective study (January 1, 2006 to December 31, 2016) of inpatientrecords of bone metastases. The diagnosis was made on clinical (bonesigns), radiological (osteolysis, bone condensation) and sometimes histologicalbasis. Result: Eighty out of 6, 1111 inpatients suffered from bone metastasiswith a hospital frequency of 1.30%. The average age was 60.74 years (range26 to 81 years). Men were predominant (53 men for 27 women) with a sex ratioof 1.96. The main complaints were pain (97.6%). chronic (90%), severe(73.8%), inflammatory (93.8%). There was sometimes a neurological complication:a motor deficit (21.3%), sensitive (13.8%). These symptoms were associatedwith fever (56.3%) and altered general state (85%). Bone metastaseshave been revealing in the vast majority of cases (93.75%); the primary cancerwas known only in 5 patients (prostate = 2, breast = 2 and cervix = 1). Bonecondensation (61.3%), osteolysis (50%) and mixed lesions (7.5%) where themain radiological lesions observed. The primary tumors were: prostatic(50%), pulmonary (18.8%), mammary (11.3%), uterine (5%), renal (2.5%),hepatic (2.5%), bladder (1.3%) and adrenal (1.3%). Conclusion: Bone metastasesaffect mostly the elderly; inflammatory spinal pain is the main symptom.Bone condensation is the most common radiologic lesion. The prostate,breast and lungs are the main primary tumors.
