摘要: PURPOSE: In osteosarcoma, prognostic factors at diagnosis other than clinical stage have not been clearly identified. The aim of this study was to determine whether human epidermal growth factor receptor 2 (HER2)/erbB-2, p-glycoprotein, or p53 expression correlated with histologic response preoperative chemotherapy event-free survival. PATIENTS AND METHODS: We performed a retrospective immunohistochemical on material obtained from patients treated the Memorial Sloan-Kettering Cancer Center T12 protocol between 1986 and 1993. Paraffin-embedded tissue identified 53 (73% enrolled onto protocol) stained for HER2/erbB-2, p53, p-glycoprotein using standard monoclonal antibodies methods. RESULTS: At time initial biopsy, 20 (42.6%) 47 samples demonstrated high levels HER2/erbB-2 expression. Higher frequencies were observed in metastatic disease presentation relapse. Expre...
