  • Title: A study of the development of fracture callus in the presence of an experimentally induced osteosarcoma.
    Author: Peretti G, Casula P, Facchini R, Marinoni EC, Torri G, Treccani degli Alfieri PG.
    Journal: Ital J Orthop Traumatol; 1976 Dec; 2(3):403-12. PubMed ID: 1072875.
    Abstract:
    The results of two experiments are reported in which the formation of an osteosarcoma was induced in mice by the intraosseous injection of Moloney's virus. In the first group of fifty mice, a complete diaphyseal fracture was carried out nine days later at the site of the tumour. In the second group of 200 mice, a partial fracture was produced at the time of injection so that immobilisation was assured. The effects of cyclophosphamide and calcitonin administration were also studied in this group. The course of the repair processes of the bone was studied in both groups, and showed that, even in the presence of an osteosarcoma, these begin and can reach completion, though obstructed and delayed by the tumour.
