Methodology: It was a descriptive, transversal study on records of patients hospitalized in Rheumatology and Oncology-Radiotherapy departments of the University Teaching Hospital of Brazzaville, Congo from 1 January 2005 to 31 July 2011 (7 years and 6 months). The diagnosis of bone metastasis was made because of the existence of bone pain, or pathological fracture, or bone swelling and a bone-condensing or mixed or osteolytic radiological image. The anatomo-pathological evidence was made after biopsy of the bone lesion or primary cancer. 3687 patients were hospitalized for active cancer, among them 81 had documented bone metastasis. Results: There were 60 men (74.1%) and 21 women (25.9%) with a sex ratio of 2.85. The average age was 53 years, ranging from 3 to 80 years. 75% of patients were more or equal to 50 years old at the discovery of the bone metastasis. Bone pain was the main mode of discovery (67.9% of cases). However, in 6.2% of cases, it was discovered incidentally. The metastasis was bone condensing in 50.7% of cases, osteolytic in 40.7% and mixed in 8.6%. They were unifocal in 25.9% and multifocal in 74.1% of cases. The Primary cancer most frequently found was that of the prostate in 55.6% of cases, breast in 20.7% and rhabdomyosarcoma in 4.9%. In 6.2% of cases, the primary site of cancer was unknown. The average survival was 25 months. Conclusion: The clinical and radiological presentation remains classic. Cancer of the prostate and breast are the main neoplasia responsible for bone metastasis in our series. The discovery of metastasis remains a major evolutionary step of cancer.展开更多

Methodology: This was a descriptive, 11-year retrospective study (January 1, 2006 to December 31, 2016) of inpatient records of bone metastases. The diagnosis was made on clinical (bone signs), radiological (osteolysis, bone condensation) and sometimes histological basis. Result: Eighty out of 6, 1111 inpatients suffered from bone metastasis with a hospital frequency of 1.30%. The average age was 60.74 years (range 26 to 81 years). Men were predominant (53 men for 27 women) with a sex ratio of 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 associated with fever (56.3%) and altered general state (85%). Bone metastases have been revealing in the vast majority of cases (93.75%);the primary cancer was known only in 5 patients (prostate = 2, breast = 2 and cervix = 1). Bone condensation (61.3%), osteolysis (50%) and mixed lesions (7.5%) where the main 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 metastases affect 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.展开更多
