Hintergrund: In der Rehabilitation stehen im Fachgebiet der Inneren Medizin muskulare Ausdauerbelastungen im Vordergrund des sporttherapeutischen Handelns. Leider ist das ambulante Rehabilitations- und Sportangebot fur viele pneumologische Patienten begrenzt, und Lungensportgruppen sind noch nicht flachendeckend vorhanden. So wurde ein ambulantes Ausdauersportprogramm mit sportmedizinischer Begleitung als sporttherapeutische Masnahme in der Pneumologie entwickelt und auf Effektivitat uberpruft. Methode: In diese Projektstudie wurden konsekutiv 31 Patienten (50 ± 15 Jahre) mit verschiedenen pneumologischen Erkrankungen eingeschlossen. Der ambulanten sporttherapeutischen Intervention (12-wochiges aerobes Ausdauersportprogramm mit ≥ 3 Einheiten a 20 – 60 min/Woche) wurde eine professionelle Leistungsdiagnostik inkl. Spiroergometrie und Laktatstufentest nach Standards der DGP und DGSP vorgeschaltet, und somit wurden die optimalen individuellen Trainingsbereiche festgelegt. Ergebnisse: Nach erfolgreicher Absolvierung des Trainingsprogramms konnten signifikante Verbesserungen in den Bereichen Luftnotempfinden (Borg-Summenwert: 65,7 ± 12,2 vs. 62,2 ± 12,6, Punkte, p = 0,013), Korperkonstitution (BMI: 25,7 ± 3,3 vs. 24,3 ± 3,2 kg/m2, p = 0,018; Korperfettanteil: 24,8 ± 5,8 vs. 23,8 ± 6,4 %, p = 0,043) sowie korperliche Leistungsfahigkeit (VO2 bei 4 mmol/l Laktat: 24,2 ± 6,9 vs. 26,5 ± 7,6 ml/min/kg, p Schlussfolgerung: Das vorgestellte ambulante Ausdauersportprogramm kann als gut durchfuhrbar angesehen werden und erwies sich auch in eigenverantwortlicher Durchfuhrung nach qualifizierter Anleitung als eine effektive sporttherapeutische Masnahme bei Patienten mit unterschiedlichen pneumologischen Erkrankungen.

Objectives Surgery has been available for the treatment of mono-metastatic, non-small cell lung cancer (NSCLC) and promising overall survival was observed in some retrospective studies with selected patients. This study investigated whether the preoperative 18-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG-PET/CT) scan influences survival in this patient group. Furthermore we tried to identify other prognostic factors associated with survival and aimed to clarify if synchronous metastases are different from metachronous disease. Methods Between 1994 and 2012, 181 patients underwent resection for solitary metastases. Sixty-six patients underwent surgery after an initial FDG-PET/CT scan, whereas 115 patients underwent conventional preoperative staging by a spiral CT scan. Results The overall 5-year survival rate was 38.8%. The 5-year survival rates after preoperative evaluation by FDG-PET/CT and by conventional CT were 58% and 33%, respectively ( p = 0.01). A higher 5-year survival rate was observed in patients without thoracic lymph node involvement (pN0: 44% vs. pN1-3: 33%, p = 0.028). In patients with a solitary pulmonary metastasis, we observed a 5-year survival rate of 45.7%, whereas in patients with extrapulmonary metastases, the 5-year survival rate was 27.1% ( p = 0.001). In patients with a locally limited primary lung cancer according to the pT descriptor, we observed a 5-year survival rate of 53.1%, whereas in patients with a pT > 1 descriptor, the 5-year survival rate was 33.6% ( p = 0.016). By multivariate analyses, we showed that preoperative FDG-PET/CT evaluation, no thoracic lymph node metastases, and sole pulmonary metastatic disease were favorable predictors of survival, whereas the time of metastasis (synchronous vs. metachronous) and maximum standardized uptake value was not. Conclusions We conclude that resection of the primary tumor and metastasectomy for mono-metastatic NSCLC can be performed after a comprehensive evaluation with FDG-PET/CT. N-stage and the site of the oligometastases have a significant influence on overall survival.

Based on the results of studies from the 1960s-1980s the current four drug combination therapy was established as standard or short course tuberculosis therapy worldwide. The regional epidemiology and the often unique conditions within a national health system create the need for specific adjustments. Over the last years these were realized by the German central committee against tuberculosis (DZK) in the recommendations for tuberculosis therapy. Because of the recent development of migration into Germany from countries with higher tuberculosis incidences an increase in tuberculosis cases is to be expected. The expected increase in tuberculosis cases will lead to more contact with tuberculosis patients even in the outpatient setting. New S2k guidelines guided by the Association of the Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF) for the treatment of tuberculosis for children and adults are under development. Before the release of the comprehensive guidelines, practical evidence for the diagnosis and treatment of uncomplicated tuberculosis is summarized in this document to meet the challenges of the recent developments.

Approximately 20% of symptomatic patients with SARS-CoV-2 infection progress to severe coronavirus disease (COVID-19) with critical hypoxemia fulfilling the criteria of acute respiratory distress syndrome (ARDS). Consistent with the classic features of ARDS, severe COVID-19 is characterised by ground glass opacities in CT imaging and diffuse alveolar damage post mortem [5] suggesting permeability-type lung edema as driver of respiratory failure. Consistent with this concept, autopsy findings show severe lung endothelial injury in patients who succumbed to COVID-19 [1]., Plasma of COVID-19 patients induces pulmonary microvascular barrier failure which increases with disease severity. Here, we report a versatile high-throughput screening platform to test for involved plasma mediators and the therapeutic potential of barrier stabilising compounds.

Background: Pulmonary nocardiosis (PN) is an uncommon but potentially life-threatening infection. Most of our knowledge on PN is derived from case reports and small case series. Increasing incidence rates of PN have been reported recently. The aim of this study was to describe the clinical course of and risk factors for PN in four Western European countries and to estimate population-based annual hospitalization rates. Methods: This was a retrospective evaluation (1995–2011) of the clinical course of and risk factors for PN in patients at 11 hospitals in four European countries (Germany, Austria, Switzerland, and the Netherlands). Population-based estimates of hospitalization rates for PN in Germany (2005 to 2011) were calculated using official German nationwide diagnosis-related groups (DRG) hospital statistics. Results: Forty-three patients fulfilled stringent criteria for proven (n = 8) and probable (n = 35) PN; seven had extrapulmonary dissemination. For these 43 patients, the major risk factors for PN were immunocompromising (83.7%) and/or pulmonary (58.1%; as only comorbidity in 27.9%) comorbidities. The median duration of PN targeted therapy was 12 weeks. Distinctive patterns of resistance were observed (imipenem susceptibility: Nocardia farcinica 33.3%; Nocardia asteroides 66.7%). The overall mortality rate was 18.9% (50% in disseminated PN). Over time, annual PN hospitalization rates remained unchanged at around 0.04/100 000, with the highest rate among men aged 75–84 years (0.24/100 000). Conclusions: PN is a rare, but potentially life-threatening disease, and mainly affects immunocompromised elderly males. Overall, annual hospitalization rates remained stable between 2005 and 2011.

Early immune responses to Mycobacterium tuberculosis (Mtb) invasion of the human lung play a decisive role in the outcome of infection, leading to either rapid clearance of the pathogen or stable infection. Despite their critical impact on health and disease, these early host-pathogen interactions at the primary site of infection are still poorly understood. In vitro studies cannot fully reflect the complexity of the lung architecture and its impact on host-pathogen interactions, while animal models have their own limitations. In this study, we have investigated the initial responses in human lung tissue explants to Mtb infection, focusing primarily on gene expression patterns in different tissue-resident cell types. As first cell types confronted with pathogens invading the lung, alveolar macrophages, and epithelial cells displayed rapid proinflammatory chemokine and cytokine responses to Mtb infection. Other tissue-resident innate cells like gamma/delta T cells, mucosal associated invariant T cells, and natural killer cells showed partially similar but weaker responses, with a high degree of variability across different donors. Finally, we investigated the responses of tissue-resident innate lymphoid cells to the inflammatory milieu induced by Mtb infection. Our infection model provides a unique approach toward host-pathogen interactions at the natural port of Mtb entry and site of its implantation, i.e., the human lung. Our data provide a first detailed insight into the early responses of different relevant pulmonary cells in the alveolar microenvironment to contact with Mtb. These results can form the basis for the identification of host markers that orchestrate early host defense and provide resistance or susceptibility to stable Mtb infection.

Streptococcus pneumoniae (S.pn.) is the most common bacterial pathogen causing community acquired pneumonia. The pore-forming toxin pneumolysin (PLY) is the major virulence factor of S.pn. and supposed to affect alveolar epithelial cells thereby activating the immune system by liberation of danger-associated molecular patterns (DAMP). To test this hypothesis, we established a novel live-cell imaging based assay to analyse mitochondrial function and associated release of mitochondrial DNA (mtDNA) as DAMP in real-time. We first revealed that bacterially released PLY caused significant changes of the cellular ATP homeostasis and led to morphologic alterations of mitochondria in human alveolar epithelial cells in vitro and, by use of spectral live-tissue imaging, in human alveoli. This was accompanied by strong mitochondrial calcium influx and loss of mitochondrial membrane potential resulting in opening of the mitochondrial permeability transition pore and mtDNA release without activation of intrinsic apoptosis. Moreover, our data indicate cellular mtDNA liberation via microvesicles, which may contribute to S.pn. related pro-inflammatory immune activation in the human alveolar compartment.

Due to an increase of drug resistant TB, alternative drugs that are not currently listed in the WHO guidelines on MDR TB treatment are currently being evaluated. Our group tested 100 susceptible, 20 MDR and 2 XDR Mtb strains against the phenothiazine derivatives thioridazine, trifluoperazine and triflupromazine. MIC testing was performed on Middlebrook 7H10 agar and was defined as the lowest drug concentration that inhibits ≥99% of the bacterial population. We confirm very good in vitro activity of phenothiazines against Mycobacterium tuberculosis. In >77% of all strains MICs of ≤10 μg/ml were found.

Loss of alveolar barrier function with subsequent respiratory failure is a hallmark of severe pneumonia. Although junctions between endo- and epithelial cells regulate paracellular fluid flux, little is known about their composition and regulation in the human alveolar compartment. High autofluorescence of human lung tissue in particular complicates the determination of subcellular protein localization. By comparing conventional channel mode confocal imaging with spectral imaging and linear unmixing, we demonstrate that background fluorescent spectra and fluorophore signals could be rigorously separated resulting in complete recovery of the specific signal at a high signal-to-noise ratio. Using this technique and Western blotting, we show the expression patterns of tight junction proteins occludin, ZO-1 as well as claudin-3, -4, -5 and -18 and adherence junction protein VE-cadherin in naive or Streptococcus pneumoniae-infected human lung tissue. In uninfected tissues, occludin and ZO-1 formed band-like structures in alveolar epithelial cells type I (AEC I), alveolar epithelial cells type II (AEC II) and lung capillaries, whereas claudin-3, -4 and -18 were visualised in AEC II. Claudin-5 was detected in the endothelium only. Claudin-3, -5, -18 displayed continuous band-like structures, while claudin-4 showed a dot-like expression. Pneumococcal infection reduced alveolar occludin, ZO-1, claudin-5 and VE-cadherin but did not change the presence of claudin-3, -4 and -18. Spectral confocal microscopy allows for the subcellular structural analysis of proteins in highly autofluorescent human lung tissue. The thereby observed deterioration of lung alveolar junctional organisation gives a structural explanation for alveolar barrier disruption in severe pneumococcal pneumonia.

Die kalkulierte Behandlung der multiresistenten (MDR) Tuberkulose (TB) nach molekularer Schnelltestung wird durch die mehrwochige Unkenntnis der Empfindlichkeit gegen Zweitlinienmedikamente erschwert. Durch die Berucksichtigung regionaler Haufungen von Resistenzen bei Migranten konnte die kalkulierte Behandlung mit Zweitlinienmedikamenten zielgerichteter erfolgen. Von 2008 bis 2013 wurden retrospektiv die Ergebnisse der kulturellen Empfindlichkeitstestung aller eingesendeten Mykobakterienstamme des Instituts fur Mikrobiologie, das mit der Lungenklinik Heckeshorn zusammenarbeitet, analysiert und auf regionale Unterschiede untersucht. Unter den Proben fanden sich 39 Mycobacterium tuberculosis-Stamme mit Multiresistenz. Als Zweitrangmedikamente wurden Linezolid (97 %), Clofazimin (95 %), Cycloserin (95 %), Capreomycin (90 %), P-Aminosalicylsaure (82 %), Moxifloxacin (79 %) und Amikacin (79 %) bei mehr als der Halfte der Stamme empfindlich getestet. Der Anteil der empfindlichen Stamme war niedriger fur Pyrazinamid (44 %), Ethambutol (28 %), Protionamid (15 %), Rifabutin (8 %) und Streptomycin (8 %). Bei den Mykobakterienstammen aus Tschetschenien (n = 14) unterschieden sich die Empfindlichkeiten gegen Amikacin (57 %) und Protionamid (36 %) signifikant von denen aus anderen Regionen. Die regional unterschiedlich ausgepragten Empfindlichkeiten gegen Zweitlinienmedikamente legen nahe, dass bei der Wahl der kalkulierten Initialtherapie von MDR TB-Patienten mit Migrationshintergrund differenziert vorgegangen werden muss.

Background Surgical treatment of patients with limited metastatic lesions from non-small cell lung cancer (NSCLC) remains controversial; however, reports suggest that a subset of patients may benefit from complete resection including metastasectomy. Methods Between 1997 and 2009, 99 patients underwent complete solitary synchronous NSCLC metastasis resection in a single center. Only patients who met the potentially curative operation criteria (ie, primary NSCLC and metastasis resection of a solitary pulmonary or solitary extrapulmonary metastases) were included for retrospective analyses within this study. Results The overall 5-year survival rate was 38%. A significantly longer survival was observed in patients without mediastinal (N2 or N3) lymph node involvement (median, 50.0 months) compared with patients who had mediastinal lymph node metastases (median, 19.0 months survival; p = 0.015). In patients with a solitary metastasis in the ipsilateral (not ipsilobar) or contralateral lung, we observed a 5-year survival rate of 48.5%, whereas the rate was 23.6% in patients with extrapulmonary metastases ( p = 0.006). In univariate analysis, a trend for a more favorable long-term survival rate was observed for patients with a histologic grade of G1 or G2 versus G3 primary NSCLC ( p = 0.058). Conclusions We conclude that metastasectomy for synchronous oligometastatic disease in NSCLC can be performed in selected patients. It appears reasonable that such patients should be considered as surgical candidates if mediastinal lymph node involvement is excluded.

Die Ausbildung von Bronchiektasen entsteht in einem „circulus vitiosus“ aus verminderter Sekretclearance, bakterieller Besiedlung, chronischer Entzundung und Gewebezerstorung. Die chronisch-progressive Lungendestruktion fuhrt zu erhohter Morbiditat und Mortalitat. Die Diagnose wird mittels hochauflosender Computertomographie („high-resolution computed tomography“, HRCT) gestellt. Bei Bestatigung von Bronchiektasen muss eine weitere Abklarung in Richtung einer moglichen Grunderkrankung begonnen werden. Aufgrund der Vielzahl der in Frage kommenden Erkrankungen ist eine strukturierte Differentialdiagnostik notwendig. Dieser Artikel erlautert die verschiedenen Ursachen von Non-CF-Bronchiektasie (NCFB) und stellt einen diagnostischen Algorithmus sowie Therapieoptionen vor. Diese Ubersicht soll Kinder- und Jugendarzten sowie Internisten als Leitfaden dienen und zur verbesserten Diagnose und Therapie von Patienten aller Altersgruppen mit Bronchiektasen beitragen.

In the article by Alsaad et al. [1] in a recent issue of the European Respiratory Journal the authors reviewed six drugs with antimicrobial activity against Mycobacterium tuberculosis (phenothiazine, metronidazole, doxycycline, disulfiram, tigecycline and co-trimoxazole) which are not listed in the World Health Organization guidelines on multidrug-resistant tuberculosis (MDR-TB) treatment, but could be potential candidates for this use. Despite of the release of new drugs (delamanid, bedaquiline), treatment alternatives are still warranted, last but not least because of treatment costs. We would like to extend this list by evaluating the anti-malaria drug mefloquine. Mefloquine has in vitro activity against MDR- and non-MDR-TB and should be evaluated in clinical studies

Die Melioidose, auch Pseudorotz genannt, ist eine durch Burkholderia pseudomallei verursachte Infektionskrankheit. B. pseudomallei ist ein gramnegatives bewegliches Bakterium. Es ist extra- und intrazellular aktiv und produziert Exo- und Endotoxine. B. pseudomallei kommt im Boden und Oberflachenwasser vor und wird bei Temperaturen unterhalb von 11 °C inaktiviert. Die Melioidose ist in Sudostasien und Nordaustralien endemisch, hier hat die Erkrankung eine Letalitat von bis zu 50 %. Sporadisch treten auch Falle in Lateinamerika und Afrika auf [2]. Die Ubertragung erfolgt uber kontaminiertes Wasser oder Erde in offene Wunden, aber auch uber Inhalation oder Verschlucken [4]. In Europa kommt der Erreger aufgrund der kalteren Temperaturen nicht endemisch vor. Jedoch werden wiederholt Erkrankungen bei Reiseruckkehrern aus den Tropen diagnostiziert. Die Inkubationszeit betragt in der Regel 1–21 Tage, kann jedoch auch mehrere Jahre dauern, sodass die Erkrankung ohne offensichtlichen zeitlichen Zusammenhang auch in Deutschland auftreten kann. Die Symptome sind sehr vielfaltig, sie konnen leicht oder sehr stark ausgepragt sein sowie lokalisiert oder generalisiert auftreten. Haufig ist eine Septikamie. Typisch sind pulmonale Manifestationen wie Abszesse, Pleuraergusse oder Entzundungen. Extrapulmonale Manifestationen sind u. a. kutane Ulzera, septische Arthritis, intraabdominelle Abszesse, Parotitis, Prostataabszesse und Enzephalitis [1]. Eine Melioidose wird durch eine Schwachung des Immunsystems begunstigt. Insbesondere Diabetes mellitus, chronische Niereninsuffizienz, Alkoholabusus, chronische Lungenerkrankungen und eine Therapie mit Glukokortikoiden sind Risikofaktoren [5]. Jedoch scheint eine HIV-Infektion die Erkrankung nicht zu begunstigen. Der Nachweis kann immunulogisch mittels Agglutinationstests mit monoklonalen Antikorpern erfolgen, dies ist eine schnelle und sensitive Methode. Auserdem kann B. pseudomallei mittels Immunfluoreszenzmikroskopie und Capture-ELISA nachgewiesen werden. Je nach verwendetem Antikorper werden auch B. mallei oder B. thailandensis erfasst. In der Regel erfolgt der spezifische Nachweis von B. pseudomallei mittels Polymerasekettenreaktion (PCR). Die Behandlung besteht aus einer 14-tagigen i.v.-Initialtherapie mit Ceftazidim oder Meropenem und anschliesender 6-monatiger oraler Eradikationstherapie zur Rezidivprophylaxe mit Trimethoprim-Sulfamethoxazol und/oder Doxycyclin [3]. Die Erkrankung kann sehr schwer und trotz antibiotischer Therapie todlich verlaufen.

Oncology - Abstract
Hintergrund: Thromboembolische Komplikationen bei Lungenkrebspatienten gelten als haufig, jedoch liegen nur wenige Daten uber deren Inzidenz vor. Zur Klarung der Haufigkeit thromboembolischer Ereignisse im arteriellen und venosen System wurden die in unserem Hause mit einem Lungenkarzinom diagnostizierten Patienten retrospektiv bezuglich des Auftretens thromboembolischer Ereignisse ausgewertet. Patienten/Methode: Alle Patienten mit Erstdiagnose eines Lungenkarzinoms wurden seit 1/2008 prospektiv erfasst und hier bis 12/2010 retrospektiv bezuglich thromboembolischer Komplikationen im venosen und arteriellen System ausgewertet unter Berucksichtigung von Tumorstadium, Histologie und platinhaltiger Chemotherapie. Bei den venosen thromboembolischen Komplikationen wurden Lungenarterienembolien und tiefe Venenthrombosen berucksichtigt, bei den arteriellen thromboembolischen Komplikationen Myokardinfarkt, mesenteriale Ischamie, peripher-arterielle Ischamie, Nierenarterienischamie und ischamischer Apoplex. Ergebnisse: In den 36 Monaten wurde in unserem Zentrum bei 1940 Patienten (1209 Manner, 731 Frauen) die Erstdiagnose eines Lungenkarzinoms gestellt, 156 kleinzellige Lungenkarzinome (SCLC; 8 %) und 1784 nichtkleinzellige Lungenkarzinome (NSCLC; 92 %). Insgesamt traten bisher bei 190/1940 Patienten (9,8 %) thromboembolische Komplikationen auf; bei 148/190 (78 %) venose und bei 51/190 (27 %) arterielle thromboembolische Komplikationen. Wir dokumentierten 82/148 (55 %) tiefe Venenthrombosen, 98/148 (66 %) Lungenarterienembolien sowie arterielle thromboembolische Ereignisse: ischamischer Apoplex 23/51 (45 %), Koronararterien 14/51 (28 %), Extremitatenarterien 12/51 (24 %), Mesenterialarterien 4/51 (7,8 %), extrakranielle hirnversorgende Arterien 3/51 (5,9 %). Diskussion/Schlussfolgerungen: Thromboembolische Ereignisse sind eine haufige Komplikation bei Patienten mit Lungenkarzinom. Auf dem Boden dieser Ergebnisse sollte der Stellenwert einer entsprechenden Primarprophylaxe erneut diskutiert werden.

Hintergrund: Mit der Entwicklung flexibler Kryosonden steht ein wichtiges Instrument fur die endobronchiale interventionelle Therapie, aber auch fur die histologische Diagnostik zur Verfugung. Verschiedene Studien vergleichen die diagnostische Effektivitat und/oder die Komplikationen der Kryotechnik mit der flexiblen Zange als Standard. Die Realitat der endoskopischen Routine setzt immer eine kombinierte Anwendung verschiedener Methoden voraus. Diese Vorgehensweise verspricht nach wie vor die hochste diagnostische Ausbeute. Wir haben die Bedeutung der Kryotechnik bei kombinierter Anwendung in der Routine fur die Diagnostik maligner Tumoren in unserem Lungenkrebszentrum untersucht. Patienten und Methode: Uber 30 Monate wurde die Anwendung der Kryotechnik, die Komplikationen und ihr diagnostischer Wert prospektiv erfasst. Dabei wurden bei jedem Patienten konventionelle Techniken je nach Indikation angewandt und die Diagnostik durch die Kryotechnik erganzt (n = 469). Ergebnisse: Ein histologischer Tumornachweis war durch die Kryotechnik deutlich haufiger moglich als durch die alleinige Zangenbiopsie (81,4 vs. 59,9 % zentral bzw. 66,2 vs 37,7 % peripher). Allerdings wird dieser Vorteil bei der Kombination anderer Nicht-Kryobiopsieverfahren geringer. Bei zentralen Befunden schatzen wir den Informationsgewinn auf 7,4 % (p = 0,02), bei peripheren Befunden ist er 19,3 % (p Schlussfolgerung: Die Kryotechnik hat neben ihrem interventionellen Wert ein hohes diagnostisches Potenzial. Das veranderte Komplikationsprofil der Technik verandert den Bedarf an Aufklarung und Masnahmen zur Sicherheit wahrend der Untersuchung.

Die nichttuberkulosen Mykobakteriosen umfassen eine Gruppe von Erkrankungen, die von Mykobakterien verursacht werden, die nicht dem Mycobacterium (M.) tuberculosis-Komplex und nicht M. leprae zugerechnet werden und durch eine breite Vielfalt in Hinsicht auf ihr Vorkommen und ihre Anpassungen an spezifische Umweltbedingungen charakterisiert sind. Einige Spezies konnen definierte Krankheitsbilder insbesondere bei Patienten mit systemischer Immunsuppression, vorbestehenden Lungenerkrankungen oder genetisch bedingter erhohter Empfanglichkeit hervorrufen. Weltweit wird eine Zunahme der Pravalenz und der Bedeutung dieser Erregergruppe beobachtet. Die vorliegenden Empfehlungen fassen aktuelle Aspekte der Epidemiologie, der Pathogenese, Klinik, Diagnostik einschlieslich mikrobiologischer Diagnostik und Resistenztestung, sowie der speziesabhangigen Therapie bei nichttuberkulosen Mykobakteriosen zusammen. Auserdem werden die besonderen Aspekte der Diagnostik und Therapie im Kindesalter und bei HIV-infizierten Patienten dargestellt.

Item does not contain fulltext BACKGROUND: Estimating attributable mortality of ventilator-associated pneumonia has been hampered by confounding factors, small sample sizes, and the difficulty of doing relevant subgroup analyses. We estimated the attributable mortality using the individual original patient data of published randomised trials of ventilator-associated pneumonia prevention. METHODS: We identified relevant studies through systematic review. We analysed individual patient data in a one-stage meta-analytical approach (in which we defined attributable mortality as the ratio between the relative risk reductions [RRR] of mortality and ventilator-associated pneumonia) and in competing risk analyses. Predefined subgroups included surgical, trauma, and medical patients, and patients with different categories of severity of illness scores. FINDINGS: Individual patient data were available for 6284 patients from 24 trials. The overall attributable mortality was 13%, with higher mortality rates in surgical patients and patients with mid-range severity scores at admission (ie, acute physiology and chronic health evaluation score [APACHE] 20-29 and simplified acute physiology score [SAPS 2] 35-58). Attributable mortality was close to zero in trauma, medical patients, and patients with low or high severity of illness scores. Competing risk analyses could be done for 5162 patients from 19 studies, and the overall daily hazard for intensive care unit (ICU) mortality after ventilator-associated pneumonia was 1.13 (95% CI 0.98-1.31). The overall daily risk of discharge after ventilator-associated pneumonia was 0.74 (0.68-0.80), leading to an overall cumulative risk for dying in the ICU of 2.20 (1.91-2.54). Highest cumulative risks for dying from ventilator-associated pneumonia were noted for surgical patients (2.97, 95% CI 2.24-3.94) and patients with mid-range severity scores at admission (ie, cumulative risks of 2.49 [1.81-3.44] for patients with APACHE scores of 20-29 and 2.72 [1.95-3.78] for those with SAPS 2 scores of 35-58). INTERPRETATION: The overall attributable mortality of ventilator-associated pneumonia is 13%, with higher rates for surgical patients and patients with a mid-range severity score at admission. Attributable mortality is mainly caused by prolonged exposure to the risk of dying due to increased length of ICU stay. FUNDING: None.

Nach Schatzungen der Weltgesundheitsorganisation (WHO) kam es im Jahr 2011 global zu 8,7 Mio. Tuberkulose(TB)-Neuerkrankungen und 1,4 Mio. Todesfallen. In Deutschland dagegen ist die TB heute eine seltene Erkrankung. Im Jahr 2011 lag die Inzidenz bei 5,3/100.000 Einwohner. Daher nimmt die arztliche Erfahrung mit diesem Krankheitsbild ab. In dieser Ubersicht werden die Standardtherapie der TB und die dabei verwendeten Medikamente beschrieben. Vor Therapiebeginn muss eine grundliche anamnestische Evaluation in Bezug auf Risikofaktoren einer resistenten TB erfolgen. Auch die bakteriologische Sicherung durch den mikroskopischen und kulturellen Erregernachweis sowie eine phanotypische Resistenztestung sind anzustreben. Die Behandlung der TB ist stets als antibiotische Kombinationstherapie angelegt. Die Wahl der Wirkstoffe hangt masgeblich vom Resistenzstatus der Erregerstamme ab. Fur weitere Informationen zur Therapie der TB sei auf die 2012 erschienenen Therapieempfehlungen des Deutschen Zentralkomitees zur Bekampfung der Tuberkulose e. V. (DZK) und der Deutschen Gesellschaft fur Pneumologie und Beatmungsmedizin (DGP) verwiesen.

Hintergrund: Die Mode des Tatowierens hat sich in westlichen Gesellschaften in den letzten zwei Dekaden sehr stark ausgebreitet. Uber medizinische Komplikationen nach der Tatowierung wurde in Einzelfalldarstellungen vielfach berichtet. Allerdings wurde eine systemische anaphylaktische Reaktion als Komplikation des Tatowierens bisher nur einmal beschrieben. Hierbei handelte es sich um eine Patientin, die bereits vorher unter schweren Allergien litt. Falldarstellung und Verlauf: Wir stellen den Fall eines 59-jahrigen Mannes vor, der funf Stunden nach einer Tatowierung eine progrediente Schwellung und Rotung entwickelte. Nach einer weiteren Stunde kam es in der Notaufnahme zu einer systemischen Anaphylaxie Schweregrad III. Es zeigte sich eine rapide zunehmende Schwellung und Rotung des tatowierten linken Arms, der linken Wange sowie von Lippen und Zunge. Allergien waren bei dem Patienten in der Vorgeschichte nicht bekannt. Der Patient sprach gut auf eine Therapie mit Prednisolon und Antihistaminika an. Die weitere Abklarung identifizierte Formaldehyd, Nickel und Mangan als Bestandteile der Farben, die als potenzielle chemische Ausloser der Symptome des Patienten infrage kommen. Einer erweiterten allergologischen Abklarung mit Prick-Test stimmte der Patient nicht zu. Schlussfolgerung: Die Kasuistik deutet darauf hin, dass Tattoofarben systemische Anaphylaxien auslosen konnen. Entscheidungstrager in Politik und Verwaltung sollten versuchen, die Anwendung bekannter starker allergener Stoffe in kommerziellen Tattoofarben wirkungsvoller zu beschranken.

The recent introduction of bronchoscopically recovered cryobiopsy of lung tissue has opened up new possibilities in the diagnosis of neoplastic and non-neoplastic lung diseases in various aspects. Most notably the morphological diagnosis of peripheral lung biopsies promises to achieve a better yield with a high quality of specimens. To better understand this phenomenon, its diagnostic options and perspectives, this study morphometrically compares 15 cryobiopsies and 18 transbronchial forceps biopsies of peripheral lung tissue a priori without considering clinical hit ratio or integration of results in the clinical diagnostic processing. Cryotechnically harvested specimens were significantly larger (mean: 17.1 ± 10.7 mm2 versus 3.8 ± 4.0 mm2) and contained alveolar tissue more often. If present, the alveolar part in cryobiopsies exceeded the one of forceps biopsies. The alveolar tissue of crybiopsy specimens did not show any artefacts. Based on these results cryotechnique seems to open up new perspectives in bronchoscopic diagnosis of lung disease.

Non-tuberculous mycobacterioses comprise a group of diseases caused by mycobacteria which do not belong to the Mycobacterium (M.) tuberculosis-complex and are not ascribed to M. leprae. These mycobacteria are characterized by a broad variety as to environmental distribution and adaptation. Some of the species may cause specific diseases, especially in patients with underlying immunosuppressive diseases, chronic pulmonary diseases or genetic predisposition, respectively. Worldwide, a rising prevalence and significance of non-tuberculous mycobacterioses is recognized. The present recommendations summarise current aspects of epidemiology, pathogenesis, clinical aspects, diagnostics - especially microbiological methods including susceptibility testing -, and specific treatment for the most relevant species. Diagnosis and treatment of non-tuberculous mycobacterioses during childhood and in HIV-infected individuals are described in separate chapters.

Nosocomial pneumonia (HAP) is a frequent complication of hospital care. Most data are available on ventilator-associated pneumonia. However infections on general wards are also increasing. A central issue are infections with multi drug resistant (MDR) pathogens which are difficult to treat particularly in the empirical setting potentially leading to inappropriate use of antimicrobial therapy. This guideline was compiled by an interdisciplinary group on the basis of a systematic literature review. Recommendations are made according to GRADE giving guidance for the diagnosis and therapy of HAP on the basis of quality of evidence and benefit/risk ratio. The guideline has two parts. First an update on epidemiology, spectrum of pathogens and antiinfectives is provided. In the second part recommendations for the management of diagnosis and treatment are given. Proper microbiologic work up is emphasized for knowledge of the local patterns of microbiology and drug susceptibility. Moreover this is the optimal basis for deescalation in the individual patient. The intensity of antimicrobial therapy is guided by the risk of infections with MDR. Structured deescalation concepts and strict limitation of treatment duration should lead to reduced selection pressure.

C(U)RB-65 (confusion, (urea7 mol · L(-1),) respiratory frequency ≥ 30 breaths · min(-1), systolic blood pressure90 mmHg or diastolic blood pressure ≤60 mmHg and age ≥ 65 years) is now the generally accepted severity score for patients with community-acquired pneumonia (CAP) in Europe. In an observational study based on the large database from the German nationwide performance measurement programme in healthcare quality, including data from all hospitalised patients with CAP during 2008-2010, different CRB-age groups (≥ 50 and ≥ 60 years) across the total CAP population and three entities of CAP (younger population aged65 years, patients aged ≥ 65 years not residing in nursing homes and those with nursing home-acquired pneumonia (NHAP)) were validated for their potential to predict in-hospital death. 660 594 patients were investigated. Mortality was n=93 958 (14.0%). In the total population, CRB-80 had the optimal area under the curve (0.690, 95% CI 0.688-0.691). However, in the younger cohort, CRB-50 performed best (0.730, 95% CI 0.724-0.736), with good identification of low-risk patients (CRB-50 risk class 1: 1.28% deaths, negative predictive value 98.7%). In the elderly, CRB-80 as the optimal age group performed worse (0.663, 95% CI 0.660-0.655 in patients not residing in nursing homes; 0.608, 95% CI 0.605-0.611 in those with NHAP). In the latter group, all CRB-age groups failed to identify low-risk patients (CRB-80 risk class 1: 22.75% deaths, negative predictive value 81.8%). Patients with hospitalised CAP aged65 years may be assessed by the CRB-50 score. In those aged ≥65 years (not NHAP) assessed by the CRB-65 score, low-risk patients are already are at an increased risk of death. In NHAP patients, even the use of CRB-80 does not identify low-risk patients and should be accompanied by the evaluation of functional status and comorbidity.

The diagnostic value of flexible bronchoscopy in the pre-operative work-up of solitary pulmonary nodules (SPN) is still under debate among pneumologists, radiologists and thoracic surgeons. In a prospective observational manner, flexible bronchoscopy was routinely performed in 225 patients with SPN of unknown origin. Of the 225 patients, 80.5% had lung cancer, 7.6% had metastasis of an extrapulmonary primary tumour and 12% had benign aetiology. Unsuspected endobronchial involvement was found in 4.4% of all 225 patients (or in 5.5% of patients with lung cancer). In addition, flexible bronchoscopy clarified the underlying aetiology in 41% of the cases. The bronchoscopic biopsy results from the SPN were positive in 84 (46.5%) patients with lung cancer. Surgery was cancelled due to the results of flexible bronchoscopy in four cases (involvement of the right main bronchus (impaired pulmonary function did not allow pneumonectomy) n=1, small cell lung cancer n=1, bacterial pneumonia n=2), and the surgical strategy had to be modified to bilobectomy in one patient. Flexible bronchoscopy changed the planned surgical approach in five cases substantially. These results suggest that routine flexible bronchoscopy should be included in the regular pre-operative work-up of patients with SPN.

Einfuhrung: Die Behandlung synchroner solitarer Lungenmetastasen beim nicht-kleinzelligen Lungenkarzinom (NSCLC) ist umstritten. So werden Satellitenmetastasen im gleichen Lungenlappen mittlerweile als T3-Tumore klassifiziert und konsequenterweise meist reseziert, da bestenfalls ein Stadium IIB (T3N0M0) resultiert. Im Gegensatz dazu werden ipsilaterale Herde in unterschiedlichen Lappen zwar neuerdings prognostisch als T4-Tumore klassifiziert und somit bestenfalls in ein Stadium IIIA eingeordnet (T4N0 – 1M0), jedoch in der taglichen Praxis meist nicht reseziert. Kontralaterale Lungenmetastasen werden, da prognostisch etwas gunstiger als extrathorakale Fernmetastasen, zwar neuerdings als M1a klassifiziert, eine chirurgische Konsequenz – wie in Einzelfallen bei solitarer Hirn- oder Nebennierenmetastase – ergibt sich hieraus jedoch nicht, da bisher eine begrundende Datenlage fehlt. Aus diesem Grund uberpruften wir in unserer Lungenklinik die Ergebnisse nach Resektion sowohl des Primartumors als auch der synchronen solitaren pulmonalen Metastase auserhalb des tumortragenden Lappens. Methoden: Wir operierten zwischen 1997 und 2007 siebenundfunfzig Patienten mit NSCLC und zeitgleicher zweiter (solitarer) maligner Lasion der Lunge, auserhalb des tumortragenden Lappens, nach entsprechender Aufklarung und Einverstandnis im Rahmen individueller Heilversuche. Der weitere Krankheitsverlauf wurde in einer Datenbank festgehalten und das Uberleben mit Kaplan-Meier-Statistik analysiert. Ergebnisse: Der Primartumor wurde in 67 % der Falle durch Lobektomie, in 9 % durch Pneumonektomie, in 2 % durch Bilobektomie und in 22 % durch Segment- bzw. atypische Resektion behandelt. Die zweite maligne Lasion und somit potenzielle solitare Metastase wurde in 83 % durch Segment- bzw. atypische Resektion, in 6 % der Falle durch Lobektomie, in 9 % durch Restpneumonektomie und in einem Fall durch Thoraxwandteilresektion behandelt. Das Gesamtuberleben aller Patienten (n = 57) betrug im Median 82 Monate (75 – 89 Monate 95 % Konfidenzintervall (KI)). Bei den synchronen Zweitkarzinomen (n = 7) lag das Uberleben im Median bei 76 Monaten (0,1 – 151 Monate 95 % KI), bei den synchronen Metastasen (n = 50) bei 82 Monaten (75 – 88 ± 95 % KI; p = 0,15). Dies entspricht einer 5-Jahres-Uberlebensrate von 56 % bzw. 77 %. Das mediane Uberleben der Patienten mit solitarer ipsilateraler Metastasierung (T4 nach UICC7) lag bei 79 Monaten (76 – 82 Monate 95 % KI), mit kontralateraler Metastase (M1a nach UICC7) bei 84 Monaten (60 – 107 Monate 95 % KI; p = 0,634). Schlussfolgerungen: Diese Auswertung zeigt, dass eine solitare Lungenmetastase (auserhalb des tumortragenden Lappens), bei ansonsten operablem NSCLC, einen kurativen chirurgischen Therapieansatz nicht von vornherein ausschliest. Bei ausgewahlten Patienten kann durch Resektion des Primartumors, Lymphadenektomie und Resektion der solitaren synchronen Lungenmetastase ein gutes Langzeituberleben erreicht werden. Da die vorgestellten Ergebnisse deutlich gunstiger sind als vergleichbare Daten von Patienten mit solitarer Hirn- oder Nebennierenmetastase, sollte entsprechend der deutschen S3-Leitlinienempfehlung fur diese Patienten in Einzelfallen auch ein chirurgisches Vorgehen bei pulmonal metastasierten NSCLC in Betracht gezogen werden.

Hintergrund: Ein 70-jahriger pneumologischer Patient mit seit vielen Jahren bestehender COPD und Sauerstofflangzeittherapie entwickelte im Verlauf seiner Erkrankung ein komplexes Beschwerdebild. Im mehrwochigen stationaren Verlauf erfolgte eine Behandlung von ausgepragten korperlichen Symptomen wie Luftnot, Angst und Schmerzen. Nach Ubernahme auf die Palliativstation war schlieslich nur noch die umfassende finale Begleitung im stationaren Setting moglich. Die in unserem Zentrum vorhandene palliativmedizinische Expertise wurde in diesem Fall zu spat in die therapeutischen Prozesse mit einbezogen. Das fuhrte zu einer schlechteren Kontrolle der oben genannten Symptome. Des Weiteren konnte der Wunsch des Patienten nach umfassender ambulanter Versorgung nicht rechtzeitig umgesetzt werden, da die Schwere des Krankheitsbildes nicht fruhzeitig erfasst wurde. Instrumente zur rechtzeitigen Erfassung eines nicht malignen pneumologischen Krankheitsbildes mit Bedarf einer zusatzlichen palliativmedizinischen Versorgung sind nicht etabliert.

Hintergrund: Das PET/CT mit F-18-Fluordesoxyglukose (FDG) hat eine hohe Sensitivitat (89 – 100 %) und zufriedenstellende Spezifitat (79 – 95 %) fur die Diagnose des NSCLC. Gegenwartig wird es uberwiegend im praoperativen Staging eingesetzt. Dies fuhrt in ca. 15 % aller Falle zu einer Diagnose von Fernmetastasen, die weder klinisch vermutet noch durch eine vorausgegangene konventionelle Bildgebung erkannt wurden. Wir pruften, ob die daraus resultierende Umstadiierung dieser Falle einen Einfluss auf das statistische Gesamtuberleben von Patienten im palliativen Stadium IV haben kann. Ziel: Vergleich des Gesamtuberlebens von Patienten mit Stadium IV NSCLC, die mittels FDG-PET/CT stadiiert wurden, mit Patienten, bei denen ausschlieslich konventionelle Bildtechnologien zum Stadiieren verwendet wurden. Methoden: Wir haben das Gesamtuberleben aller Patienten unserer Klinik mit der Neudiagnose eines NSCLC im Stadium IV aus dem Jahre 2009 ( n = 254) analysiert. 96 /254 (38 %) Patienten wurden mittels FDG-PET/CT stadiiert, 158 /254 (62 %) mittels konventioneller Methoden (CT-Gruppe). Die Uberlebensdaten wurden mittels Kaplan-Meier-Statistik verglichen. Ergebnisse : Die Patienten in der PET/CT-Gruppe waren junger (65 ± 11) als die der CT-Gruppe (68 ± 10 Jahre, p = 0,008). Das mediane Gesamtuberleben aller Patienten lag bei 246 Tagen (Bereich: 217 – 275 Tage); 338 Tage fur die PET/CT-Gruppe (Bereich: 247 – 429 Tage) und 207 fur die CT-Gruppe (Bereich: 161 – 253 Tage, p = 0,001), entsprechend einem Unterschied im medianen Gesamtuberleben von 131 Tagen (4,4 Monate). Schlussfolgerung : Der heutige Einsatz des FDG-PET/CT im Rahmen des uberwiegend praoperativen Stagings beim NSCLC identifiziert eine prognostisch gunstigere Gruppe an fernmetastasierten Patienten. Deren konsequente Umstadiierung in ein palliatives Stadium IV fuhrt zu einer therapieunabhangigen Verlangerung des mittleren Gesamtuberlebens innerhalb dieses Stadiums.

Die Datenlage zur Versorgungsqualitat von Patienten mit Lungenkrebs in Deutschland ist unzureichend. Zwar existiert mit der S3-Leitlinie Lungenkarzinom aus dem Jahr 2010 eine gute wissenschaftliche Handlungsgrundlage fur die mitunter komplexen Behandlungspfade, jedoch ist nicht belegt, inwieweit die entsprechenden Leitlinienempfehlungen bundesweit umgesetzt werden oder welche Therapien uberhaupt bei einer der prognostisch schlechtesten Tumorentitaten zur Anwendung kommen. Im Rahmen des Nationalen Krebsplans aus dem Jahr 2008 wurden konkrete Handlungsziele zur systematischen Verbesserung der onkologischen Versorgung in Deutschland formuliert. Als ein wesentliches Ziel wird eine bundesweite Neugestaltung und Vereinheitlichung von Tumordokumentation und Qualitatssicherung zur nachhaltigen Steigerung der Versorgungsqualitat gefordert. Dieser Ubersichtsartikel erlautert die zentralen Begrifflichkeiten und untersucht, inwieweit die Handlungsziele des Nationalen Krebsplanes beim Lungenkarzinom bislang umgesetzt wurden.

Die „International Standards for Tuberculosis Care“ (ISTC) wurden u. a. von der Weltgesundheitsorganisation (WHO) als Grundlage dafur entwickelt, dass weltweit die Betreuung von Tuberkuloseerkrankten – auch jenseits staatlicher Tuberkuloseprogramme und offizieller Gesundheitssysteme – auf Basis international abgestimmter, wenn moglich evidenzbasierter Standards erfolgt. Damit wenden sich die ISTC primar an ressourcenarme Lander mit hoher Tuberkulosepravalenz. Hier vorgestellt wird die deutsche Ubersetzung der 2009 veroffentlichten 21 Standards zu den Bereichen Diagnostik, Therapie, Koinfektion (insbesondere mit HIV) und Public Health. Die begleitenden Kommentare stellen dar, wie diese Standards in Deutschland aufgrund der hier vorhandenen medizinischen Moglichkeiten bzw. landesspezifischer Besonderheiten anzupassen sind.

Several new international recommendations have been published since the German Central Committee against Tuberculosis (DZK) published its recommendations for drug treatment of tuberculosis (TB) in 2001 and for chemoprevention of latent tuberculosis infection (LTBI) in 2004. These international publications have been integrated in the present new recommendations which describe both the treatment of active TB and preventive treatment, pointing out specific adaptations for Germany. Separate sections deal with the current management of mono-, poly-, and multiresistance or drug intolerance, of TB in children, of different forms of extrapulmonary TB, of LTBI and of special situations such as HIV infection, renal or hepatic insufficiency, infection following BCG instillation in bladder cancer or in case of adverse drug reactions. The following aspects differ from the previous recommendations: A three-drug regimen for the so-called fully susceptible minimal TB is no longer recommended in adults. A dosage of 15 mg/kg body weight of ethambutol for adults is regarded as sufficient. Four secondline drugs (supplemented by pyrazinamide, where appropriate) are recommended for multidrug-resistant tuberculosis (MDR-TB). MDR-TB should be treated over a period of at least 20 months, with an injectable drug administered for a minimum of 8 months (initial phase). Ciprofloxacine and ofloxacine are no longer used to treat TB. It is also recommended to offer an HIV test to all TB patients to complement antiretroviral therapy, if necessary, and to adapt the antituberculous therapy accordingly.

Context: The treatment of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) is consistently difficult. Besides resistances, drug availability can be problematic and costs for therapy are high. Aims: Our aim was to evaluate alternatives in treatment of MDR and XDR TB other than using second-line drugs. Materials and Methods: We analyzed retrospectively the minimal inhibitory concentrations (MICs) of first-line drugs for 44 multidrug–resistant Mycobacterium tuberculosis isolates determined in our institute over a period of 20 years (1990 - 2010, n = 44). Drug susceptibility testing (DST) was performed using the proportion method on Lowenstein–Jensen Medium or Middlebrook 7H10 agar. MICs were defined as the lowest drug concentration after two-fold serially diluted concentration of the drugs that inhibits growth of more than 99.0% of a bacterial proportion of the tested M. tuberculosis within 14 to 21 days of incubation at 37°C. Statistical Analysis Used: Summation. Results: The MICs of isoniazid and ethambutol were equal or slightly above the critical concentration in most of the strains (92% and 84%, respectively), defined as “low-level resistance”. Rifampicin and streptomycin exhibited very high MICs in most of the strains (100% and 77%, respectively), indicating a “high-level resistance”. Conclusion: Our results indicate that isoniazid and ethambutol could still play a role in treating MDR and XDR TB patients if low-level resistance is detected. Quantitative DST seems to be promising for the recognition of residual drug activity, but has to be confirmed by clinical studies.

The aim of this study was to investigate treatment failure (TF) in hospitalised community-acquired pneumonia (CAP) patients with regard to initial antibiotic treatment and economic impact. CAP patients were included in two open, prospective multicentre studies assessing the direct costs for in-patient treatment. Patients received treatment either with moxifloxacin (MFX) or a nonstandardised antibiotic therapy. Any change in antibiotic therapy after >72 h of treatment to a broadened antibiotic spectrum was considered as TF. Overall, 1,236 patients (mean ± SD age 69.6 ± 16.8 yrs, 691 (55.9%) male) were included. TF occurred in 197 (15.9%) subjects and led to longer hospital stay (15.4 ± 7.3 days versus 9.8 ± 4.2 days; p < 0.001) and increased median treatment costs (€2,206 versus €1,284; p

para-Aminosalicylic acid (PAS) is commonly used in the treatment of drug-resistant tuberculosis, including multidrug-resistant tuberculosis. Since its first use in the 1940s, hypersensitivity reactions frequently limit its use in clinical practice. Cases of successful desensitization against PAS using orally administered ascending doses are described in the literature. A 25-year-old patient with severe pulmonary multidrug-resistant tuberculosis developed drug fever with rash, acral cyanosis, and shivering immediately after the intravenous application of PAS. Hard gelatine capsules containing PAS dry substance were prepared in order to desensitize this patient. Encapsulated PAS was applied orally in rising doses starting with 10 mg/day and doubling the dose every 2 days until the half-maximal dose of 5,120 mg was reached. Desensitization covers a period of 21 days. Subsequent intravenous application of PAS at the full dose was well tolerated. In a 12-month follow-up period, no more allergic reactions appeared. PAS dry substance encapsulated in hard gelatine capsules and administered orally in rising concentrations may be useful to archive a successful desensitization for subsequent intravenous applications.

BACKGROUND: The care of lung cancer patients in Germany has not been systematically evaluated yet. The aim of this article is to give an overview on the current state of lung cancer care on the basis of existing data. METHODS: In April and May 2010, a literature search was performed in order to collect relevant information concerning epidemiology as well as diagnostic, therapeutic (systemic therapy, radiotherapy, surgery, palliative therapy), and interdisciplinary structures in lung cancer treatment. RESULTS: The published database on lung cancer care in Germany is overall deficient. Treatment of lung cancer patients is mainly located in hospitals, particularly in chest clinics or specialised departments. The access of hospitals for an outpatient treatment as provided per § 116b SGB V has not yet been realised in all German states. CONCLUSIONS: A systematic and prospective evaluation of lung cancer care is necessary in order to better allocate resources in the future.
