Outcomes of comprehensive treatment for primary osteosarcoma

Purpose: This study aimed to evaluate the clinical features and outcomes of osteosarcoma to identify prognostic factors and determine new strategies to improve overall survival. Patients and Methods: We retrospectively analyzed 12 cases of osteosarcoma treated at our hospital from 2012 to 2017. Tumor site, tissue type, stage, treatments, adverse effects, postoperative limb function, surgical margin, and final outcomes were evaluated. Results: All patients received chemotherapy, and 10 underwent wide resection. The Musculoskeletal Tumor Society scores were more than good in all cases, and the 3-year survival rate was 73.3%. Two patients are alive with disease, eight have remained disease-free, and two died of the disease. Three of the four recurrent cases involved the pelvis. Conclusion: The treatment of primary osteosarcoma with wide resection in our department, therefore, yielded favorable outcomes. However, improved treatment strategies are needed for pelvic and advanced cases.
