Abstract

The phenomenon of cancer metastasis remains poorly understood. We discuss here various conceptual frameworks that attempt to rationalize the mechanisms by which tumors acquire metastatic ability. Portrayal of cancer as a somatic Darwinian process occurring within a tissue fails to fully explain the phenomenon of metastatic competence. The biology of pre-neoplastic cells also complicates this picture, since the phenotypes of normal cellular precursors are clearly relevant to metastatic behavior following transformation. Recent experimental results help to shed light on these and other considerations regarding the molecular mechanisms of malignant progression.
