In 336 patients with various tumors of the limb bones underwent limb sparing surgery with different kind of reconstructions. The oncological results of the treatment of these patients have been analysed. Local relapse after limb sparing interventions because of extremities bone tumors developed in 4,17% of all cases. In most cases, local recurrences have been observed in patients with bone sarcomas high degree of malignancy (7,14%) and low degree of malignancy (2,82%). In 57,1% of cases, local recurrences developed in patients with osteogenic sarcoma IIB stage. The appearance of local recurrence was a bad prognostic factor for patients with bone sarcomas high grade, because it reduced 5-year survival rate almost 2 times. The overall 5-year survival of patients with bone sarcomas high grade of malignancy were (59,67 +/- 5,69)%, and 5-year relapse-free survival rate--(55,23 +/- 5,52)%. Local recurrences more often developed after the use of distraction method of surgery--in 16% of all reconstructive operations, including 12% of the cases with bone tumors of high degree of malignancy, which should be considered when choosing this method of reconstruction. |
