Chondrosarcoma of bone: an oncological and functional follow-up study.
We retrospectively analysed the course of 42 out of 45 patients suffering from different chondrosarcomas which were treated surgically. We found a prospective 5- and 10-year survival of 64% for both time intervals. Follow-up examination was possible in 21 of 45 patients. Most of them were staged as NED, one as AWD, and 8 of 45 were lost to follow-up. From 16 dead patients 12 died of the disease and 4 of unknown but not to tumor related reasons. Survival was depending significantly on the histopathological grade, and the stage according to Enneking's surgical staging system. Eleven out of forty-five patients developed metastases within a mean period of twelve months after surgery. The survival of these patients was significantly reduced. Patients with centrally located tumors exhibited a distinct but non-significant worse survival than those suffering from peripheral tumors. In 18% (8 of 45) recurrence of the tumor was evident within a mean period of 24 months (5-85). Functional evaluation was performed in 21 out of 28 alive patients. After a mean follow-up time of 72 months the mean score was 64% (23-100). Females exhibited a distinct but non-significant better result, the same was observed for peripheral locations compared to centrally located tumors. Regarding age, grade, and line of resection no tendency of any dependence was detected, but worst results were seen in those with a stage III tumor and dedifferentiated CS.
