Abstract
We studied on 25 cases of chondrosarcoma clinically, radiologically and histopathologically. Then prognostic factors to the survival rate were examined. These cases comprised 17 males and 8 females (primary chondrosarcoma: 17 cases, secondary: 8 cases).
Five chondrosarcomas occurred in the scapula, 4 in the femur, 4 in the humerus, and 3 in the pelvis and other bones. Radiologically, calcification was observed in all cases and periosteal reaction in 3 cases. High uptake of RI was observed in all cases with Tc-bone scintigraphy. Five years cumulative survival rate of 25 cases was 68% and ten years survival rate 61%.
Significant difference was found in 5 years survival rate between primary chondrosarcomas and secondary chondrosarcomas, and between the cases with high value of serum alkaline phosphatase and the cases with normal value.
