Chemotherapy in Osteosarcoma: Current Strategies
Introduction: Osteosarcoma is the most common primary malignant bone tumor in children and adolescents accounting for 4% of all pediatric malignancies. Approximately 20% of children present with metastatic disease at diagnosis and it remains, unquestionably the most important factor affecting long term survival. Prior to 1970, the prognosis of patients with osteosarcoma was dismal, with a 10–20...
متن کاملIs Tc99m-MIBI scintigraphy a predictor of response to pre-operative neoadjuvant chemotherapy in Osteosarcoma?
Objectives: Multidrug resistance (MDR), which may be due to the over expression of P-glycoprotein (Pgp) and/or MRP, is a major problem in neoadjuvant chemotherapy of osteosarcoma. The aim of this study was to investigate the role of Tc-99m MIBI scan for predicting the response to pre-operative chemotherapy. Materials and Methods: Twenty-five patients (12 males and 13 females, aged between 8 and...
متن کاملEnrichment of osteosarcoma stem cells by chemotherapy
Osteosarcoma is the most common primary malignant bone cancer in children and adolescents. Emerging evidence has suggested that the capability of a tumor to grow is driven by a small subset of cells within a tumor, termed cancer stem cells (CSCs). Although several methods have been explored to identify or enrich CSCs in osteosarcoma, these methods sometimes seem impractical, and chemotherapy en...
متن کاملMultiple-drug chemotherapy for the primary treatment of osteosarcoma of the extremities.
Fifty-five cases of osteosarcoma of the extremities were treated between 1972 and 1976 by combined surgery and chemotherapy (vincristine, adriamycin and methotrexate in medium doses) for 18 months. The follow-up ranges from 30 to 80 months (mean = 48 months). Twenty-six patients remained free from any evidence of disease, two had local recurrences but no metastases and 27 had metastases (four o...
متن کاملPrognostic Factors in the Survival of Patients Diagnosed with Primary Non-Metastatic Osteosarcoma with a Poor Response to Neoadjuvant Chemotherapy
INTRODUCTION Identification of variables that determine the prognosis for osteosarcoma may enable stratification of patients into subgroups with better or worse risk of local recurrence, metastases and death due to the disease. Discovery of such prognostic factors would permit selection of a subgroup of at-risk patients, with the aim of improving the therapeutic effectiveness. OBJECTIVE To id...
