Regional distribution of bone metastases in skeletal system

26976

Objective: Bone metastases are the most common malign lesions of skeletal system. The aim of this study is to determine regional distribution of bone metastases detected scintigraphically. Methods: Ninety-seven patients (53 male, 44 female) with primary malignancy who performed bone scintigraphy in our clinic between January 2012 and August 2013 included to study. The mean age of patients was 59±15.9 years (range 19-84). The patients who had bone metastasis and regional distribution of these metastases were detected. Results: Bone metastasis was detected in 38 (39.2%) of all patients. The metastases were multipl in 32 (84.2%) patients and single in 6 (15.8%) patients. Fifteen of malignancies that metastasize to bone were prostate cancer in 15 (39.5%) patients, breast cancer in 8 (21%) patients, lung cancer in 2 (5.3%) patients, urinary bladder cancer in 3 (7.9%) patients and other malignancies (rectum, stomach, cervix, lymphoma etc.) in 10 (26.3%) patients. Ninety-two metastasis regions were detected. 24 (26.1%) of them were vertebrae, 15 (16.3%) of them were pelvic bone, 17 (18.5%) of them were costa, 6 (6.5%) of them were upper extremity, 12 (13%) of them were lower extremity, 6 (6.5%) of them were calvarium, 6 (6.5%) of them were sternum, 4 (4.35%) of them were scapula and 3 (3.3%) of them were clavicula. Conclusion: Bone metastases are detected in two thirds of metastatic cancer cases. The most common site of bone metastases is axial skeletal system and vertebrae take the first place in this system. Bone scintigraphy is the most important imaging modality used in the evaluation of bone metastases.
