Consideration of a range of clinical and basic studies conducted at the National Cancer Institute which explore the nature of the tumor biology of lung identify the limitations of using chemotherapy for the treatment of advanced lung cancer. No single mechanistic explanation for lung cancer's chemoresistance is apparent, although considerable information about the biology of lung cancer and some of its clinical consequences have been elucidated. In contrast to previous works from our group, this presentation will focus principally on studies of the nature of drug resistance with non-small cell cancer. An alternative combined modality strategy for lung cancer control is to focus on epithelial progression of lung cancer using local modalities while it is still confined to the bronchial epithelium. Particular high risk populations may be appropriate to determine if local tools such as photodynamic laser therapy can be effective in this application. To deal with the underlying biochemical perturbations resulting from critical exposure of the bronchial epithelium to carcinogens, rational biochemical intervention with 13 cis retinoic acid are being evaluated in several clinical trials. An evolution towards more effective lung cancer.
