Abstract. According to the prevalence of bone sarcomas, chondrosarcoma ranks second after osteosarcoma and accounts for 10-15% of all cases of primary malignant bone tumors (90% of this number accounts for primary chondrosarcoma). Ribs and sternum are a fairly common localization of chondrosarcoma (about 12% of cases). The main method of treatment for chondrosarcoma of the sternum and ribs is the surgical method. However, in mesenchymal variant of chondrosarcoma and high-grade chondrosarcoma treatment is carried out according to the osteosarcoma protocol (neoadjuvant chemotherapy-surgical treatment – adjuvant chemotherapy). Relapses after surgical treatment of chondrosarcoma with lesions of the sternum or ribs can reach 50%.
Key words: chondrosarcoma, relapse, reconstructive stage.
