Abstract: Objective To study the clinical effect of neoadjuvant chemotherapy combined with limb salvage surgery for osteosarcoma. Methods Based on the previous methods of treating osteosarcoma, 56 patients were divided into the traditional limb salvage group (A group) and the modern limb salvage group (B group), 28 cases for each. The traditional limb salvage surgery + postoperative chemotherapy regimen were used in group A, and modern limb salvage regimen was performed in group B, ie neoadjuvant chemotherapy + limb salvage surgery + postoperative chemotherapy. The CTX + VCR +MTX+ ADM protocol was used in the chemotherapy regimens. The metastasis/recurrence rate, the 1-year, 2-year and 3-year survival rates, limb function, and clinical efficacy were compared between the two groups. Results The metastasis/recurrence rate and the mortality rate after 3 years in the two groups were compared. The B group was lower than that of the group A (P<0.05). The excellent rate of limb function and clinical efficacy were higher in the B group than that of in the group A (P<0.05). Conclusion Neoadjuvant chemotherapy combined with limb salvage surgery may reduce the metastasis/recurrence rate and mortality of osteosarcoma patients, improve limb function and increase clinical efficacy.
