title: [Prognosis in fibrosarcoma of bone].
abstract: A retrospective study of 42 patients with bone fibrosarcoma was carried out. A new highly informative index--tumor growth rate--is suggested. It is a ratio of tumor maximum diameter to case history length (Rtg = L, CM/t, month). Three histologically-identified grades of fibrosarcoma malignity are discussed. They are based on the variation in metastasis development and survival rates. As a result of mathematical treatment of the findings, 8 characteristics of bone fibrosarcoma were identified which influenced prognosis. A multi-factorial analysis of the data was undertaken using said characteristics. Indexes were calculated for each characteristic and tabulated to prognosticate 3-year survival of patients with fibrosarcoma of the bone.
