title: [Tumor prognostic factors in chondrosarcoma of the locomotor system. Apropos of 180 cases].
abstract: One hundred and seventy-eight patients suffering from 180 chondrosarcomas have been treated by the orthopaedic department of Cochin Hospital. Actuarial survival in these patients was 67 per cent after five years, 62 per cent after 10 years and 59 per cent after 15 years. The two main bases for survival prognosis were: --the histoprognostic grade in O'Neal and Ackerman's classification (survival after 5 years: 83 per cent for grade 1, 75 per cent for grade 2, and 15 per cent for grade 3); --the quality of the surgical resection (survival after 5 years: 78 per cent in cases of carcinological resection, and 52 per cent in cases of incorrect resection). Keeping the limb did not reduce the chances of a cure. Patients treated recently have a better prognosis than those treated before 1970: this improvement was mostly because carcinological treatment was used more often. The same prognostic factors govern local recurrences.
