Organ-preserving operations at the present stage of combined treatment of osteogenic sarcoma of long bones in children

Osteogenic sarcoma is a malignant tumor in the second decade of life [10, 25]. The incidence of it is quite high - 1.6-2.8 per 1 million children under the age of 15 per year [26]. Advances in modern chemotherapy have made it possible to increase the survival rate of patients from 0-5% in the past decades to 60-70% today [6, 9, 26, 42]. This raised the question of replacing the previously used crippling surgical techniques - amputations and exarticulations with limb-sparing operations and the development of rational approaches to choosing an organ-preserving technique in each specific case [25, 26].
