Abstract
BACKGROUND We aim to implement an immune cell score model in routine clinical practice for resected non-small-cell lung cancer (NSCLC) patients (NCT03299478). Molecular and genomic features associated with immune phenotypes in NSCLC have not been explored in detail. PATIENTS AND METHODS We developed a machine learning (ML)-based model to classify tumors into one of three categories: inflamed, altered, and desert, based on the spatial distribution of CD8+ T cells in two prospective (n = 453; TNM-I trial) and retrospective (n = 481) stage I-IIIA NSCLC surgical cohorts. NanoString assays and targeted gene panel sequencing were used to evaluate the association of gene expression and mutations with immune phenotypes. RESULTS Among the total of 934 patients, 24.4% of tumors were classified as inflamed, 51.3% as altered, and 24.3% as desert. There were significant associations between ML-derived immune phenotypes and adaptive immunity gene expression signatures. We identified a strong association of the nuclear factor-κB pathway and CD8+ T-cell exclusion through a positive enrichment in the desert phenotype. KEAP1 [odds ratio (OR) 0.27, Q = 0.02] and STK11 (OR 0.39, Q = 0.04) were significantly co-mutated in non-inflamed lung adenocarcinoma (LUAD) compared to the inflamed phenotype. In the retrospective cohort, the inflamed phenotype was an independent prognostic factor for prolonged disease-specific survival and time to recurrence (hazard ratio 0.61, P = 0.01 and 0.65, P = 0.02, respectively). CONCLUSIONS ML-based immune phenotyping by spatial distribution of T cells in resected NSCLC is able to identify patients at greater risk of disease recurrence after surgical resection. LUADs with concurrent KEAP1 and STK11 mutations are enriched for altered and desert immune phenotypes.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer-related death in all Nordic countries which, though similar in demographics and healthcare systems, have noticeable differences in lung cancer survival. Historically, Denmark and Finland have had higher lung cancer incidences and lower survival than Norway and Sweden. All four countries have national cancer registries. Data in these registries are often compared, but their full potential as a source of learning across the Nordic countries is impeded by differences between the registries. In this paper, we describe and compare the Nordic registries on lung cancer-specific data and discuss how a more harmonized registration practice could increase their usefulness as a source for mutual learning and quality improvements. METHODS We describe and compare the characteristics of data on lung cancer cases from registries in Denmark, Finland, Norway and Sweden. Moreover, we compare the results from the latest annual reports and specify how data may be acquired from the registries for research. RESULTS Denmark has a separate clinical lung cancer registry with more detailed data than the other Nordic countries. Finland and Norway report lung cancer survival as relative survival, whereas Denmark and Sweden report overall survival. The Danish Lung Cancer Registry and the Swedish Cancer Registry do not receive data from the Cause of Death registries in contrast to the Finnish Cancer Registry and the Cancer Registry of Norway. CONCLUSION The lung cancer registries in Denmark, Finland, Norway and Sweden have high level of completeness. However, several important differences between the registries may bias comparative analyses.

Abstract
To facilitate the detection of invading tumor cells in a three dimensional coculture assay in vitro, the reporter gene Escherichia coli beta-galactosidase (lacZ), was transfected into a human large-cell lung carcinoma cell line GaL23. Multicellular spheroids initiated from the transfected cell line, GaL23LZ, were confronted with fragments of human bronchial tissue differing in their surface composition. While an intact surface epithelium was found to obstruct both adhesion and invasion of tumor cells, an exposed basal lamina augmented adhesion, migration and invasion of tumor cells into the normal tissue. Tumor cells, migrating on the surface of the bronchial fragments, were found to migrate between the epithelial cells and the basal lamina. Fibroblast covered stromal fragments, derived from resected non-small cell lung cancers, were found to be more edible to the invading tumor cells than subepithelial stromal fragments from normal bronchi. The lacZ transfection made it possible to quantitatively analyze the invasive process. While the transfection neither changed the invasive ability of the tumor cells in vitro or in vivo nor their growth pattern in monolayers, three dimensional growth represented by spheroid morphology and clonogenicity in soft agar was significantly changed. This model offers an in vitro system to study qualitative and quantitative aspects of tumor-host relationships in a complex microenvironment which has several similarities to the in vivo situation.

Abstract
To study invasion of lung cancer in vitro a novel three-dimensional coculture assay consisting of living human tissues has been developed. Multicellular spheroids initiated from a new large-cell lung carcinoma cell line (GaL23), found to be invasive in immunodeficient mice, were confronted with precultured bronchial fragments derived from mucosal biopsies obtained during routine fiberoptic bronchoscopy. The bronchial fragments consist of a stromal core with scattered fibroblasts covered by a continuous surface epithelium resting on a basal lamina. During the first 2 wk of confrontation, a gradual retraction of the bronchial epithelium with subsequent adhesion of the tumor cells to the underlying basal lamina occurred. The following week, a limited invasion of tumor cells into the bronchial stroma was seen. To facilitate the entrance of tumor cells through the mucosal surface, the surface epithelium was removed prior to coculture by ethylenediaminetetraacetic acid (EDTA) buffer treatment. Upon confrontation, GaL23 cells then rapidly attached to and migrated on the exposed basal lamina and an increasing number of tumor cells was seen in the stroma during the first week of culture. This model offers opportunities for studying mechanisms of lung cancer adhesion, migration, and invasion using human bronchial mucosa as the natural target tissue.

Abstract
The supply of fresh bronchial tissue from human donors for in vitro culture is limited. Routine fiberoptic bronchoscopy offers a safe and easy procedure for obtaining minor biopsies and we wanted to see if the material provided could be used for organ culture by using a simple liquid overlay technique. Bronchial biopsies were cut into fragments 400-500 microns and kept immersed in a standard serum-supplemented medium for 40 days. An agar base prevented adhesion of the tissue. By light and electron microscopy it was shown that the tissue fragments had a differentiated epithelium at their surface throughout the culture period. An outgrowth of epithelial cells on the scaffold of the exposed stroma, covering the surface of the whole fragment, occurred within the first 5 days of culture. This epithelium was partly ciliated, 2-4 cell layers thick with squamous and cuboidal cells and expressed epithelial markers (cytokeratin and Ber-Ep4). The amount of cilia increased during the first 15 days of culture. The epithelium rested on a neosynthesized basement membrane as visualized by electron microscopy and immunohistochemistry with antibodies directed against collagen IV, laminin, and fibronectin. The central stroma consisted of loose connective tissue with fibroblasts. This simple tissue culture model combines maintenance and neoformation of bronchial epithelium on top of a living natural substrate, thus enabling direct biological studies on clinical biopsy material under perfectly viable conditions.

Abstract
Swimming is said to have low asthmogeneity especially when compared with other physical activities. Four young athletes who participated in heavy swimming exercise are reported as having symptoms of exercise-induced asthma (EIA). Three of them started to develop the symptoms after several years of training and had no former history of asthma. In the fourth, the asthma was diagnosed in childhood but the EIA-symptoms here exacerbated by swimming. All four experienced more symptoms when the air in the swimming pool was warm, or when there was a strong smell of chlorine. Two of the athletes reported having no symptoms when they swam in outdoor pools and had only minor symptoms, or none at all, when they did other formes of physical exercise, including running. In all four their swimming performance was hampered by their respiratory symptoms. Two of the swimmers improved when they inhaled steroids and adrenerg-beta 2 agonists, and continued their swimming carrier. The cases suggest that an irritant may provoke asthma symptoms in susceptible swimmers. Volatile compounds from chlorination of the pools are suspected as possible irritant agents.

Abstract
A group of chest physicians, general practitioners, clinical pharmacologist and pharmacists appointed by the Institute of Pharmacotherapy, University of Oslo has evaluated the present knowledge about treatment of chronic obstructive lung disease. The group discusses today's medical treatment of this rather numerous group of patients. It is stated that, to a high degree, the treatment of these patients lacks proper documentation, and that treatment needs to be tested out on an individual basis. The group proposes a flow chart for this purpose.
