Heterogeneity of the MYCN Oncogene in Neuroblastoma
11 Mar 2009
Abstract excerpt
PURPOSE: MYCN amplification is an important therapy-stratifying marker in neuroblastoma. Fluorescence in situ hybridization with signal detection on the single-cell level allows a critical judgement of MYCN intratumoral heterogeneity. EXPERIMENTAL DESIGN: The MYCN status was investigated by fluorescence in situ hybridization at diagnosis and relapse. Heterogeneity was defined as the simultaneous presence of...
