Abstract
- A statistical analysis was made on 59 patients of bone tumors who were treated at medical center from March, 1971 to February, 1978. The results were as follows. 1. Thirty nine cases(66%) were benign and twenty cases (34%) were malignant 2. Osteochondroma was the most common benign bone tumor (38.5%) and followed by simple bone cyst(17.9%), enchondroma(10.3%), osteoid osteoma(10.3%) and giant cell tumor(7.7%). 3. The knee joint area was the most common site of osteochondroma(95%) and its peak incidence was in the second decade. 4. Two of three cases of giant cell tumor were recurred at six months and three years after surgical intervention. 5. 11 cases(55%) out of 20 malignant bone tumor were primary tumors of osteogenic sarcoma(9 cases), Ewing's sarcoma(1 case) and multiple myeloma(1 case). Rest of 9 cases(45%) were metastatic bone tumors. 6. The primary organs of the metastatic bone tumor were kidney(2 cases), thyroid and lung(each 1 case), but the 5 cases were undetectable. The most common site of metastasis were spine and pelvis.
