Loss of ErbB2 Expression in Pulmonary Metastatic Lesions in Osteosarcoma

Abstract

It is suggested that overexpression of ErbB2 decreases within individual osteosarcomas as they become metastatic. Overexpression of ErbB2 may not play an important role in the development of pulmonary metastases of osteosarcoma. Further data are needed before ErbB2 can be used in making clinical decisions for osteosarcoma patients.
