Using a chemically defined medium containing hydrocortisone, insulin, transferrin, 17 beta-estradiol and selenium, with or without serum supplementation (2.5% v/v), continuous cell lines can be established from 72% of all fresh biopsy specimens of small cell lung cancer (SCLC) containing tumor cells. No differences were observed in the rate of establishing(More)
In the decade since the last Lancet Seminar on lung cancer there have been advances in many aspects of the classification, diagnosis, and treatment of non-small-cell lung cancer (NSCLC). An international panel of experts has been brought together to focus on changes in the epidemiology and pathological classification of NSCLC, the role of CT screening and(More)

BACKGROUND The incidence of malignant mesothelioma continues to increase, but the disease remains difficult to detect early and treat effectively. METHODS The authors review the pathogenesis, incidence, clinical presentation, diagnosis, pathology, and both standard and experimental treatments for mesothelioma. RESULTS When possible, surgery(More)
STUDY OBJECTIVES Proteins of the nucleotide excision repair pathway repair DNA damage. The excision repair cross-complementing (ERCC) gene family reduces damage to DNA by nucleotide excision and repair. Impaired nuclear excision repair could lead to increased genomic instability that in turn could lead to a more malignant phenotypic behavior of tumors. We(More)
BACKGROUND Because cells progressing to cancer must proliferate, marker proteins specific to proliferating cells may permit detection of premalignant lesions. Here we compared the sensitivities of a classic proliferation marker, Ki-67, with a new proliferation marker, MCM2, in 41 bronchial biopsy specimens representing normal mucosa, metaplasia, dysplasia,(More)
BACKGROUND Although a large number of epidemiological studies have examined the role of aspirin in the chemoprevention of colon cancer and other solid tumors, there is a limited body of research focusing on the association between aspirin and lung cancer risk. METHODS We conducted a hospital-based case-control study to evaluate the role of regular aspirin(More)
INTRODUCTION We assessed expression of p85 and p110α PI3K subunits in non-small cell lung cancer (NSCLC) specimens and the association with mTOR expression, and studied effects of targeting the PI3K/AKT/mTOR pathway in NSCLC cell lines. METHODS Using Automated Quantitative Analysis we quantified expression of PI3K subunits in two cohorts of 190 and 168(More)
BACKGROUND Lung cancer is the leading cause of cancer-related mortality. Improved understanding in the molecular biology and genetics of lung cancer has resulted in the identification of individual genes, gene expression profiles, and molecular pathways that may be useful for clinical management decisions. METHODS We focused on recent molecules and(More)
INTRODUCTION Amplification of the fibroblast growth factor receptor 1 (FGFR1) gene has been described in tumors of non-small-cell lung cancer (NSCLC) patients. Prior reports showed conflicting rates of amplification frequency and clinical relevance. MATERIALS AND METHODS We developed a reliable real-time quantitative PCR assay to assess the frequency of(More)
