Abstract
Introduction. Canine osteosarcoma is a most common bone tumor in dogs, usually involving long tubular bones lesion. Limb-sparing treatment method allows to save extremity functionality and sufficiently improve quality of life in comparison with amputation.Aim. To analyze the survival rates and local results after limb-sparing treatment of canine osteosarcoma using bio-implantation – de-immunized allogenic bone populated with recipient stromal mesenchymal cell preparation.Materials and methods. Group of 25 dogs underwent a combined treatment including cisplatinum chemotherapy (60–70 mg/m2 intravenously infusion at 14–21 day intervals, up to 4 cycles) and wide segmental resection of the affected bone with a bioimplant defect replacement. Overall survival, progression-free survival and local recurrence frequency in the group were analyzed.Results. Overall survival median was 321 day, and progression-free median was 222 days. 4 (16,6 %) cases of local relapse were recorded, 2 of which were confirmed by radiography and histological examination, and 2 other by radiography only.Conclusion. Efficiency of the canine appendicular osteosarcoma combined limb-sparing treatment is comparable with amputation practice results (according to scientific literature) while foregoing method is preferable due to higher life quality of patients.
