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)
PURPOSE Cancer survival rates are improving, and the focus is moving toward quality survival. Fertility is a key aspect of quality of life for cancer patients of childbearing age. Although cancer treatment may impair fertility, some patients may benefit from referral to a specialist before treatment. However, the majority of studies examining patient recall(More)
PURPOSE Minichromosome maintenance protein 2 (MCM2) is a component of the prereplicative complex. It is essential for eukaryotic DNA replication and is only expressed in proliferating cells. The prognostic utility of MCM2 compared with Ki-67, another marker of proliferating cells, on survival of patients with non-small-cell lung cancer (NSCLC) was studied.(More)
PURPOSE The treatment of patients with advanced non-small-cell lung cancer (NSCLC) is based on clinical trials experience. Molecular characteristics that impact metabolism and efficacy of chemotherapeutic agents are not used for decision making. Ribonucleotide reductase subunit 1 (RRM1) is crucial for nucleotide metabolism, and it is the dominant molecular(More)
PURPOSE The initial goal of this study was to test the immunologic and clinical effects of a new cancer vaccine consisting of dendritic cells (DC) transduced with the full-length wild-type p53 gene delivered via an adenoviral vector in patients with extensive stage small cell lung cancer. EXPERIMENTAL DESIGN Twenty-nine patients with extensive stage small(More)
CYP2A6 (cytochrome P450 2A6), which was first identified as the human coumarin 7-hydroxylase, is the most important enzyme in nicotine C-oxidation. The enzyme also metabolically activates the tobacco specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in vitro. Polymorphisms in the CYP2A6 gene may thus impact on both smoking behavior(More)
PURPOSE We assessed whether chemotherapy selection based on in situ ERCC1 and RRM1 protein levels would improve survival in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Eligible patients were randomly assigned 2:1 to the trial's experimental arm, which consisted of gemcitabine/carboplatin if RRM1 and ERCC1 were low,(More)
Six new non-small-cell lung cancer (NSCLC) cell lines were established directly from human tissue or indirectly via nude mouse xenografts in serum-supplemented media with success rates of 8% and 13%, respectively. They comprised one adenocarcinoma (ADLC-5M2), two squamous cell carcinomas (EPLC-32M1, EPLC-65H), two large cell carcinomas (LCLC-97TM1,(More)
The effect of human recombinant leukocyte interferon A (IFN-alpha A) and DL-alpha-difluoromethylornithine (DFMO) as single drugs and in combination on the in vitro growth, cell cycle distribution, activity of the enzyme L-dopa decarboxylase, and expression of the c-myc and N-myc oncogenes was studied in human lung cancer cell lines. In vitro growth(More)
