The oncogene addition concept was established to explain how some cancers that contain multiple genetic, epigenetic, and chromosomal abnormalities are dependent on or are “addicted” to one or more genes for both maintenance of the malignant phenotype and cell survival. Weinstein and Joe summarize current experimental and clinical evidence of this concept and describe some of the molecular mechanisms of this phenomenon. The use of molecular targeted agents in combination with cytotoxic agents, and the advances in systems biology and network theory can help to facilitate an optimal treatment approach.
