Background: Pleomorphic carcinoma (PC) of the lung is an aggressive epithelial neoplasm composed of giant and/or spindle tumor cells and associated with short survival. Most patients are cigarette smokers. The tumor susceptibility gene P-450 1A1 (CYP1A1) is involved in the activation of polycyclic aromatic hydrocarbons, including benzo[a]pyrene, producing DNA-damaging epoxides that lead to G:C→T:A point mutations. Isoleucine (Ile)-valine (Val) and Val-Val genotypes of the CYP1A1 exon 7 polymorphism are associated with an increased risk for lung cancer in certain populations.
