Abstract:
The anthors studied the 152 cases of primary bone tumors statistically during the period of 7 years and 4 months from Janusry, 1980 to April, 1987 at the department of orthopaedic surgery, St. Benedict Hospital, Pusan and the department of anatomic pathology, Pusan National University Hospital. The results of the study were summsrized as follows; l. Of the 152 cases of primary bone tumors, benign tumors were 128 cases(84.2%) and malignant tumors were 24 cases(15.8%). 2. Of benign bone tumors, the most common type was osteochondroms(34 cases, 26.6%), followed by fibrous dysplasia(25 cases, 19.5%), giant cell tumor(14 cases, 10.9%) and enchondroma(11 cases, 8.6%). 3. Of malignant bone tumors, the most common type was osteosarcoma(14 cases, 58.3%), followed by chondrosarcoma(5 cases, 20.8%), Ewing's sarcoma(3 cases, 12.5%) and myeloma(1 case, 4.2%). 4. Age distribution of benign bone tumors showed that most cases(76.4%) occured under 30-years old. Among malignant bone tumors, most of osteosarcoma and Ewing's sarcoma occured between 10-and 20-yesrs old. 5. The male to female ratio of overall benign bone tumors was 1.1: 1, and that of maligant bone tumors was 1.2: 1. There was no sexual difference. 6. The favorite sites of benign bone tumors were femur(31 cases, 23.1%), maxilla or mandible(31 cases, 23.1%), tibia(22 cases, 16.4%) and rib(11 cases, 8.2%) and those of malignant bone tumors were freguently femur(12 cases, 50.0%), followed by tibia(5 cases, 20.8 %) and pelvis(4 cases, 16.7%). 7. The most frequent manifestations in benign bone tumors were mass or swelling(62.7%), followed by pain or tenderness(33.9%) and disturbed motion or function(10.2%), but those were mostly pain or tenderness(73.9%), followed by mass or swelling(52.2%) and pathologic fracture(13.0%) in malignsnt bone tumors.8. The duration of symptoms in benign bone tumors was less than 6 months in 39.1% and less than 1 year in 44.6%, but less than 6 months in 70.9% and less than 1 year in 87.6% in malignant bone tumors. The duration of symptoms in malignant bone tumors was much shorted than that of benign bone tumors.
