title: [Fibrosarcoma of bone].
abstract: The authors have treated forty-five cases of fibrosarcoma of bone between 1949 and 1979. Tumours with chondrogenesis or osteogenesis to any extent have been excluded from the study. The conclusions are that fibrosarcoma represent 10 p. 100 of all bone tumours. Microscopy was difficult and in some cases it was not easy to determine both the fibroblastic origin and the presence of malignancy. Eight per cent of the tumours were primary and 20 p. 100 secondary. The global results indicated 40 p. 100 survival after five years. Twenty-four cases were treated by amputation of which twenty-two were followed up and fifteen were alive after five years. In nine cases, resection was performed. Recurrence occurred in five cases, three of which had to be amputated of which two survived. Two others were treated by irradiation without success. Ten cases were treated primarily by irradiation of which only three survived after heavy dosage. Proximally situated tumours had a very poor prognosis with no survival. The prognosis appeared to be better in those under forty years of age (55 p. 100 survival) than over forty years (11 p. 100 survival).
