Lung cancer is the leading cancer killer in the United States today. T
he current methods of treatment, radiation and various chemotherapies,
have been used with some success; however, early detection remains th
e key to successful therapy. Current clinical trials indicate that an
improvement of available therapies is needed. Consequently, the develo
pment of new approaches to treatment is foremost in the minds of resea
rchers. Advances in molecular medicine have produced new drugs that ca
n protect normal cells from chemotherapy-induced toxicities, resulting
in enhanced drug delivery with few dose reductions. This review will
discuss some of the advances that have been made in understanding the
molecular biology of lung cancer as well as the current and most promi
sing methods of treatment used for various forms of lung cancer. The p
otential contribution of cytoprotectors to enhance the safety and effe
ctiveness of these therapies will be examined.
