Protocol Number: 09-C-0103 ![]()
- Lung cancer is the leading cause of cancer deaths among men and women worldwide. - Despite modern surgical, radiation, and chemotherapeutic interventions, the prognosis for patients with lung cancer remains poor, with an overall cure rate of less than 15%. - Genetic polymorphisms in drug-metabolizing enzymes, transporters, growth factor and hormonal receptors, DNA repair enzymes, and transcription factors might affect an individual's response to chemotherapy and radiation. - Interindividual differences in efficacy and toxicity of cancer chemotherapy and radiation are especially important given the narrow therapeutic index of these modalities. - Many of these differences have not been extensively explored in patients with lung cancer. Objectives: - To better understand the genotype-phenotype relationship between genetic polymorphisms and clinical outcomes, with a focus on overall survival, following lung cancer therapy. - To better understand differences in outcome between Caucasian and African American patients being treated for lung cancer as a function of genotype. - To establish a DNA repository for the investigation of polymorphisms related to outcomes in lung cancer. Eligibility: - All individuals with the diagnosis of lung cancer being treated at the Washington D.C. Veteran's Affairs Hospital or the Medical Oncology Branch of the National Cancer Institute. Design: - A single 7 ml sample of venous blood will be obtained from all patients enrolled onto this study, for isolation of DNA. - Polymorphisms in the following genes: ABCB1, ABCG2, COMT, CYP17, CYP19, CYP1B1, CYP1A1, CYP1A2, CYP2C8, CYP2C9, CYP2J2, CYP3A4, CYP3A5, DPYD, EPHX2, ERalpha, ERbeta, ERCC1, ERCC2, GSTP1, HIF1A, MPO, MTHFR, NQO1, p53, PPARD, SLCO1B3, TYMS, UGT1A1, VEGF, VEGFR, EGFR, SLC28A1, CDA, XRCC1, OCT1, and OCT2 will be analyzed by the Clinical Pharmacology Program. - Patients will be followed at the medical oncology clinic at the Washington DC VA Hospital or the National Cancer Institute and the following information will be recorded in a confidential database: age, gender, race/ ethnicity, smoking history, histology, stage, treatment(s) received, response, toxicity (grades 3-5), time to disease progression, time to death. - Associations between genetic polymorphisms and response to therapy, toxicity and clinical outcomes will be analyzed.
