title: Cytogenetics and molecular genetics of lung cancer.
abstract: The development and progression of lung cancer is a multistep process characterized by the accumulation of numerous genetic and epigenetic alterations, some of which occur early in the course of disease. In this review, we summarize cytogenetic imbalances and molecular genetic/epigenetic changes seen in human small-cell and non-small-cell lung cancer. Alterations of tumor suppressor genes and oncogenes leading to perturbations of key cell-regulatory and growth-control pathways are highlighted. The translational implications of molecular biomarkers for risk assessment, early detection, and monitoring of chemoprevention trials are discussed.
