We have studied the prognostic factors affecting the survival rate in 11 patients with chondrosarcoma. Of those, six died of multiple pulmonary metastases and the overall 5-year survival rate was 38.4%.
The most significant prognostic factor was the histologic grade, and the 5-year survival rates in grade 1, 2, 3 were 100%, 0%, 25%, respectively. The location of the chondrosarcoma, and whether it was a peripheral or a central type, also seemed to be a good prognostic factor. The 5-year survival rate of the peripheral type was 66.7% as compared with 21.4% for the central type. Adjuvant therapy such as chemotherapy and irradiation had no effect on the survival rate.
