Selection of Surgical Methods in the Treatment of Upper Tibia Osteosarcoma and Prognostic Analysis.

BACKGROUND

We aimed to explore the clinical effects and prognosis of different surgical methods in upper tibia osteosarcoma.

METHODS

Among 112 patients with proximal upper tibia osteosarcoma, 40 patients were treated with amputation, 20 patients were treated with massive osteoarticular allograft, and the remaining 52 cases were treated with tumor resection and artificial joint replacement.

RESULTS

Recurrence was observed in 2 cases (5%) in the amputation group, in 6 cases (30%) in the massive osteoarticular allograft group, and in 6 cases (12%) in the tumor resection and artificial joint replacement group (P = 0.021). The lung metastasis rates were 40% in the amputation group, 40% in the massive osteoarticular allograft group, and 38% in the tumor resection and artificial joint replacement group (P = 0.986). The survival rates at 1, 3, and 5 years were 95%, 75%, and 45%, respectively, in the amputation group, 95%, 75%, and 35%, respectively, in the massive osteoarticular allograft group, and 92.3%, 78.8%, and 53.8%, respectively, in the tumor resection and artificial joint replacement group (P > 0.05).

CONCLUSIONS

The selection of the optimal surgical method for upper tibia osteosarcoma should be made according to the individual circumstances of the patient. Our study has significance for reducing the incidence of surgical complications and improving the quality of postoperative life.
