[Prognostic significance of osseous lesions in acute lymphoblastic leukemia in children].

Full skeletal survey was performed on 54 children presenting over a 6-year period (1973-1979) with acute lymphoblastic leukaemia (ALL). Findings that were considered attributable to leukaemia included metaphyseal bands, osteolytic lesions and periosteal reactions. One or more of these roentgenographic findings was observed in 24 children (44%). The mean duration of remission and of survival was much shorter in cases with multiple bone involvement (3 or more lesions) than in those where bone involvement was absent or limitated at 1 or 2 bone lesions.
