- Abstract
Background: A fundamental argument against minimally invasive oncological chest surgery is the risk of overlooking pulmonary nodules due to a lack of intraoperative palpation. In the literature this risk in the treatment of primary lung cancer is given as up to 8.4 % and as more than 15 % in the surgical treatment of pulmonary metastases. Objective: The aim of this study was to evaluate if modern computed tomography (CT) is sensitive enough to replace intraoperative palpation and justify a minimally invasive approach. Patients and methods: The medical records from 92 patients who underwent 95 open lung resections due to pulmonary malignancies from April 2010 through September 2011 at the Medical School Hannover were retrospectively analysed. A comparison was carried out between the lesions detected preoperatively by CT and those removed during surgery and histologically confirmed as being malignant. Patients with more than five nodules suspected of being malignant in the preoperative CT scan were excluded. Results: According to the final histopathological examination 125 malignant nodules were resected and 2 of these were not detected in the preoperative CT scan, which were performed in external hospitals with a slice thickness of 5 mm and 8 mm, respectively. This represents a sensitivity of 98 % for all CT scans in terms of detection of pulmonary nodules. With thin slice CT (slice thickness up to 1.5 mm) a sensitivity of 100 % was even achieved. Conclusion: The results demonstrate that a high sensitivity of thin slice CT for detection of lung nodules can be achieved. Based on these results the categorical reservation with respect to thoracoscopic resection of pulmonary metastases should be reconsidered in suitable patients where a minimally invasive resection is possible. The extent of lymph node dissection is not influenced by these data. Further studies with larger sample sizes are warranted to confirm these results. [ABSTRACT FROM AUTHOR]

Background: Lung cancer is the leading cause of cancer-related death in most western countries in both, males and females, accounting for roughly 20���25% of all cancer deaths. For choosing the most appropriate therapy regimen a definite diagnosis is a prerequisite. However, histological characterization of bronchoscopic biopsies particularly with low tumor cell content is often challenging. Therefore, this study aims at (a) determining the value of DNA methylation analysis applied to specimens obtained by bronchoscopic biopsy for the diagnosis of lung cancer and (b) at comparing aberrantly CpG loci identified in bronchoscopic biopsy with those identified by analyzing surgical specimens. Results: We report the HumanMethylation450-based DNA methylation analysis of paired samples of bronchoscopic biopsy specimens either from the tumor side or from the contralateral tumor-free bronchus in 37 patients with definite lung cancer diagnosis and 18 patients with suspicious diagnosis. A differential DNA methylation analysis between both biopsy sites of patients with definite diagnosis identified 1303 loci. Even those samples were separated by the set of 1303 loci in which histopathological analysis could not unambiguously define the dignity. Further differential DNA methylation analyses distinguished between SCLC and NSCLC. We validated our results in an independent cohort of 40 primary lung cancers obtained by open surgical resection and their corresponding controls from the same patient as well as in publically available DNA methylation data from a TCGA cohort which could also be classified with high accuracy. Conclusions: Considering that the prognosis correlates with tumor stage at time of diagnosis, early detection of lung cancer is vital and DNA methylation analysis might add valuable information to reliably characterize lung cancer even in histologically ambiguous sample material., publishedVersion

Diese Arbeit beschäftigt sich mit der computerassistierten Diagnose (CAD) zur Detektion von Lungenknoten. Der Lungenkrebs ist einer der häufigsten Todesursachen auf der Welt. Der Hauptauslöser für Bronchialkarzinome ist der vermehrte Tabakkonsum. Die schädlichen Stoffe können Zellen schädigen und somit dem Atmungsorgan schaden. Um die Sterberate zu senken, ist eine Frühdiagnose des Bronchialkarzinoms notwendig, da diese Lungenerkrankung meistens symptomfrei entsteht. Bei späteren Stadien ist eine vollständige Heilung des Öfteren nicht möglich. Daher ist der Einsatz von CAD Systemen von großer Bedeutung. CAD Systeme sind in der Lage, anhand von „lernenden“ Algorithmen, Lungenknoten zu detektieren. Für das Trainieren der Systeme wird eine große Datenbank benötigt. Umso mehr Lernmaterial zur Verfügung steht, desto besser können CAD Systeme trainiert werden. Die künstliche Intelligenz spielt dabei eine wichtige Rolle, da während des Lernprozesses keine Beispiele auswendig gelernt, sondern bestimmte Muster eingeprägt werden. Diese erworbenen Kenntnisse werden dann an unbekannte Daten angewendet. Laut einigen Studien konnte festgestellt werden, dass anhand CAD Systeme die Detektionsrate und Sensitivität erhöht werden konnten. Weitere Studien haben auch gezeigt, dass CAD Systeme mehr an Bedeutung in der Medizin gewonnen haben. Die Befundungszeit konnte auch wesentlich gesenkt werden. Zusätzlich können CAD Systeme als Lerntools für Radiolog*innen und Radiologietechnolog*innen dienen. Da viele Berufsgruppen in der Radiologie häufig zusammenarbeiten ist es notwendig, sich gegenseitig zu unterstützen und bei Verdacht auf eine gefährliche Krankheit, Ärzt*innen auf die Röntgenaufnahme aufmerksam zu machen. Zu beachten ist auch, dass auf dem Gebiet der Radiologie, die kontinuierliche Entwicklung und Aktualisierung von Verfahren beziehungsweise Modalitäten mehr zunimmt. Als Radiologtechnolog*in ist es daher wichtig, stets auf dem neuesten Stand der Technik zu sein. This thesis deals with computer-assisted diagnosis (CAD) for the detection of lung nodules. Lung cancer is one of the leading causes of death in the world. The main trigger for bronchial carcinoma is increased tobacco consumption. The harmful substances can damage cells and thus damage the respiratory system. In order to reduce the mortality rate, the early diagnosis of bronchial carcinoma is necessary, as this lung disease usually develops without symptoms. Complete healing is often not possible in later stages. Therefore, the use of CAD systems is of great importance. CAD systems can detect lung nodules using machine learning algorithms. A large database is required to train the systems. The more learning material is available, the better CAD systems can be trained. Artificial intelligence plays an important role here, since no examples are learned by heart during the learning process, but rather certain patterns are imprinted. This acquired knowledge is then applied to unknown data. According to some studies, it could be determined that the detection rate and sensitivity could be increased using CAD systems. Further studies have also shown that CAD systems have gained more importance in medicine. The time of diagnosis could also be reduced significantly. In addition, CAD systems can serve as learning tools for radiologists. Since many professional groups in radiology often work together, it is often necessary to support each other and to draw the attention of doctors to the X-ray if a dangerous disease is suspected. It should also be noted that in the field of radiology the continuous development and updating of procedures and modalities is increasing. As a radiologist technologist, it is therefore important to always be up to date with the latest technology.

Background: Ultrasound elastography has emerged as a non-invasive tool to “palpate” the previously unpalpable deeply buried organs and has established itself as a reliable, radiation-free and a cost-effective diagnostic equipment for quantifying the degree of stiffness of various normal and pathological tissues in the body. Given the aerated nature of pulmonary parenchyma; studies on lung elastography are scarce. Very few studies examined the use of ARFI in peripheral pulmonary consolidations (PPCs) and almost all of them excluded consolidations accompanied by pleural effusion (PE). The purpose of this study was to evaluate the diagnostic performance of ultrasound (US) point shear wave elastography (pSWE) using Acoustic Radiation Force Impulse (ARFI) technology in different benign and malignant PPCs. Methods: 107 consecutive patients with PPCs who underwent sonographic examinations between April to December 2020 at the university hospital of Marburg, Germany were recruited in the study. A verbal consent was obtained from each patient to perform an ARFI study of the PPC. 20 patients (n=20) were excluded due to the following reasons: 10 patients (n=10) due to measurement’s failure, 5 patients (n=5) due to incompliance (breath holding) with invalid measurements, 5 PPCs (n=5) due to uncertain diagnosis. Finally, 87 patients (n=87) were included in the final analysis. The ARFI studies were retrospectively analyzed and correlated to the final diagnosis. All patients received a conventional lung US examination in addition to an ARFI study (11 valid measurements in meters per second (m/s) were obtained for each PPC). Atelectatic consolidations accompanied by pleural effusions (PE) were also included. The diagnosis was confirmed by means of cyto-histological examination (performed in 73/87 (83.9%) of the patients) or by means of computer tomography (CT) and or chest-X-ray in correlation to the clinical picture (a CT scan was available in 84/87 (96.6%) of the cases). A receiver operating characteristic (ROC) analysis was implemented to examine the mean ARFI velocities (MAV) for potential cut-off values between benign and malignant PPCs. The study was approved by the local ethics committee of the Philipps-university in Marburg. Results: The 87 patients (49 males and 38 females) had a mean age of 65±14 years (range 28-88 years). The mean body mass index (BMI) was 24.1±3.5 Kg/m2. History of smoking and chronic pulmonary disease (CPD) was present in 61% (53/87) and 36% (31/56), respectively. 55% (48/87) of the PPCs were accompanied by PE. There was 58 benign PPCs (bPPCs) and 29 malignant PPCs (mPPCs). Large consolidation’s size was suggestive of malignancy (p=0.01), the mean size of mPPCs was 6.26 ±3.12 cm and of bPPCs 4.02 ±1.98 cm. A cutoff size of 4.75 cm has a sensitivity and specificity of 65.5% and 82.5%, respectively in diagnosing mPPCs (AUC=0.729, 95% CI= 0.577-0.881). Consolidations accompanied by PE had lower MAV values and were more likely to be benign (P 0.05). bPPCs demonstrated significantly lower MAV values as mPPCs (1.82±0.97 vs. 3.05±0.73 m/s) (p

Trotz des enormen Forschungsaufwands führt Lungenkrebs immer noch zu den meisten durch Krebs verursachten Todesfällen. In den letzten Jahren wurden mit gezielten Therapien und Immuncheckpoint-Inhibitoren zwar Fortschritte erzielt, allerdings sprechen nicht alle Patienten auf diese Behandlungen an oder entwickeln schlussendlich Resistenzen. Daher müssen auch andere Ansätze, wie die Immunzelltherapie, in Betracht gezogen werden. In dieser Arbeit wird die Hypothese aufgestellt, dass der Knockout von A20 zu verbesserten anti-Tumor Eigenschaften von NK-Zellen führt und dass der adoptive Transfer dieser Zellen eine Alternative zur Behandlung von LUAD darstellt. Zu diesem Zweck wurden A20Δ/+- und A20Δ/Δ- NK-Zellen aus Mausmodellen isoliert, charakterisiert, und ihre zytotoxischen Eigenschaften sowohl in vitro als auch in vivo getestet. A20Δ/+- NK-Zellen zeigten keine Unterschiede, weder in der IFNγ-Expression noch in in-vitro killing assays. A20Δ/Δ- NK-Zellen zeigten eine reduzierte Viabilität, und konnten nicht in Kultur gehalten werden. Dementsprechend wurde die Hypothese widerlegt und gezeigt, dass A20-defiziente NK-Zellen keine sinnvolle Option zur Behandlung von KRAS-getriebenen LUAD sind. Dennoch bleiben NK-Zellen eine attraktive Option und die Modifikation anderer Gene könnte zu vielversprechenderen Effekten führen. Um Tumor-Immunzellinteraktionen zu untersuchen, ist es notwendig, ein Tumormodell zu verwenden, das eine starke Immunantwort hervorruft. Klassischen Modellen fehlt jedoch meist diese Eigenschaft. Ein zweites Ziel dieser Arbeit war es, eine Tumorzelllinie zu charakterisieren, die OVA exprimiert, ein Protein, das Neoantigene in Krebserkrankungen simuliert und eine starke Immunantwort auslösen soll. Kaplan-Meier- und FACS-Analysen wurden durchgeführt, um OVA+ und OVA--Tumore zu verglichen und die Auswirkungen von OVA auf die Immunzellinfiltration zu bestimmen. Obwohl OVA+-Tumore das Überleben der Mäuse verlängerten, zeigte die FACS-Analyse unveränderte Immunzellinfiltration, was darauf hindeutet, dass OVA+ Tumorzellen keine stärkere Immunantwort hervorrufen. Eine detailliertere Beschreibung ist daher notwendig, um das Modell zu verstehen und um es für die Untersuchung von Tumor-Immunzellinteraktionen nutzen zu können. Despite the enormous effort being made, lung cancer is still the number one cause for cancer related deaths. Indeed, major progress has been made in recent years as targeted therapies and immune checkpoint blockade replaced chemotherapy as the first choice of treatment for advanced lung cancer. However, not all patients respond to ICB and both ICB and targeted therapy eventually result in resistance. Therefore, other promising approaches, such as immune cell therapy, must be considered as well. In this thesis it is hypothesized that the knockout of A20 results in enhanced anti-tumorigenic properties of NK cells, and that the adoptive transfer of these cells is a safe alternative to treat LUAD. For this purpose, several mouse models were used to generate and isolate both A20Δ/+- and A20Δ/Δ- NK cells. The cells were characterized, and their cytotoxic properties were tested both in vitro and in vivo. A20Δ/+- NK cells did not show significant differences regarding both IFNγ expression and in vitro killing properties. A20Δ/Δ- NK cells showed a clearly reduced viability as they cannot be maintained in culture after isolation. Taken together the results demonstrate that the hypothesis was disproved and that A20 deficient NK cells are not a reasonable option to treat KRAS driven LUAD. Nevertheless, NK cells remain an attractive target and the modification of other genes might lead to more promising effects. To study tumor-immune cell interactions, it is necessary to use a tumor model that elicits strong immune responses. However, classical models usually lack this desired characteristic, due to low mutational burden. A second aim of this thesis was to characterize a tumor cell line that expresses OVA, a protein that mimics neoantigens in human cancers and thus should induce strong immune cell activation. Kaplan-Meier- and FACS analysis were performed to demonstrate the impact of OVA with respect to immune cell infiltration. Although OVA expressing tumors prolonged the survival of mice, FACS analysis did not reveal changes in immune cell infiltration, suggesting that OVA expressing tumor cells do not elicit a stronger immune response. A more detailed characterization is therefore needed to completely understand the tumor model and to be able to use it for the study of tumor-immune cell interactions. vorgelegt von: Georg Petroczi MolecularBiotechnology Enthält Literaturangaben Wien, FH Campus Wien, Masterarb., 2021

Lungenkrebs ist die häufigste Ursache für krebsbedingte Todesfälle weltweit.[1] In den letzten Jahren hat jedoch die sogenannte Präzisionsmedizin die Krebstherapie von Nicht-kleinzelligen Lungenkrebs-Patienten (NSCLC-Patienten) revolutioniert. Die Identifizierung von prädikativen Biomarkern sowie das detaillierte genetische Verständnis ermöglichte die Entwicklung niedermolekularer Verbindungen zur gezielten Inhibierung der aberranten Zielstrukturen genetisch definierter Patientengruppen. Durch die gezielte Adressierung der onkogenen Zielproteine können die Nebenwirkungen verringert werden, wodurch die Präzisionsmedizin eine vielversprechende Alternative zur platinbasierten Chemotherapie darstellt.[2,3] Genetische Mutationen, die zur Entstehung und zur Progression von NSCLC führen, sind häufig in den Rezeptor-Tyrosinkinasen zu finden. Hierbei sind im Rahmen dieser Arbeit vor allem der epidermale Wachstumsfaktor-Rezeptor (EGFR) sowie der humane epidermale Wachstumsfaktor-Rezeptor 2 (Her2) zu nennen.[4,5] Die Entstehung von Resistenzmutationen innerhalb der Kinase-Domäne von EGFR, während der Behandlung mit zielgerichteten Tyrosinkinase-Inhibitoren, erfordert das stetige Aufklären der Resistenzmechanismen sowie die Entwicklung neuer Wirkstoffe.[6] Daher ist ein detailliertes Verständnis der Mutanten sowie der Protein-Inhibitor-Interaktionen auf molekularer Ebene für die Entwicklung neuartiger Verbindungen erforderlich. Die Proteinkristallographie stellt eine wichtige Methode zur Strukturaufklärung dar. [7,8] Allerdings sind bis zur finalen Kristallstruktur viele Herausforderungen wie das Konstruktdesign, die Proteinexpression in unterschiedlichen Expressionssystemen sowie die Proteinreinigung und die Identifizierung geeigneter Kristallisation-bedingungen zu meistern. Nach Optimierung der genannten Arbeitsschritte konnten im Rahmen dieser Arbeit verschiedene Kristallisationssysteme Krebs-relevanter EGFR-Varianten etabliert werden, mit deren Hilfe ein verlässliches Wachstum qualitativ hochwertiger Proteinkristalle in Komplex mit niedermolekularen Verbindungen für die Strukturaufklärung ermöglicht werden konnte. Neben dem Interaktionsnetzwerk der Verbindungen und es Zielproteins konnten wichtige strukturelle Einblicke für weitere strukturbasierte Designansätze neuartiger Inhibitoren sowie Optimierungen bereits vorliegende Inhibitoren identifiziert werden. Im Rahmen dieser Arbeit konnten insgesamt 47 finale Kristallstrukturen der EGFR-Mutationsvarianten generiert werden, von denen bisher zwölf in der Protein Data Bank publiziert wurden. [1] F. Bray, J.

Background Cancer in advanced stages represents one of the biggest challenges for medicine in achieving the best possible treatment results regarding patients' expectations. Several fac- tors may influence the treatment. One is the patients' cooperation (compliance and adherence), whereas the declarative attitude towards therapy has been rarely investigated. This study aimed to investigate how the attitude towards chemotherapy and its side effects looks like and whether this attitude can be seen as a prognostic factor for survival. Methods There were analyzed data from a completed randomized Phase III trial in non-small cell lung cancer "sequential Mono vs. dual vs. triple combination therapy". A total of 272 patients with NSCLC in tumor stage IIIB or IV aged between 34-75 from 24 clinics in Germany were analyzed. The patients should fulfill before and after the treatment a ques- tionnaire on attitude towards chemotherapy. There were ten examples of chemotherapy side effects, and the patients were asked about their acceptance according to their poten- tial benefit. The patients had to keep a diary during the treatment, where the toxicity symptoms, according to NCI-CTC, and laboratory test results of the study participants were recorded. Furthermore, there was a quality of life questioner, according to EORTC, fulfilled. Results The vast majority of the patients were ready to endure the side effects of chemotherapy. The biggest concerns presented here vomiting, rashes, and numbness of the limbs. The acceptance increased with the potential profit of the therapy. However, it was observed that those who were not accepting these side effects had a longer OS; the longer, the higher the grade of potential treatment benefit rejection. This trend was seen in all exam- ples of the side effects. It was statistically relevant (Log-rank p=0,027) in the question concerning the attitude towards blood transfusion, where the OS was 1,5 higher in those who rejected blood transfusion even if its acceptance hypothetically led to 1-year life prolongation (12,5 vs. 8 months). Additionally, it was observed that behind the known factors as the Karnofsky Index or the presence of metastasis also transfusion during the first cycle might be seen as a statistically relevant unfavorable survival predictive factor (Log-rank p=005) Discussion In the study, the most important aspect for the patients was life prolongation even if as- sociated with more side effects. However, the negative attitude towards side effects of the treatment, especially blood transfusion, was surprisingly a favorable prognostic factor for survival. An explanation of this trend remains hidden, but it may indicate that psychologic attitude plays an underestimated role in therapy success. Furthermore, in the study, blood transfusion during the first cycle of chemotherapy might be rated as a negative prognostic factor. To answer the question, if these observations are clinically relevant further studies on these issues are needed., Hintergrund Krebserkrankungen in fortgeschrittenem Tumorstadium stellen einer der größten Herausforderung für die Medizin beim Erzielen der bestmöglichsten Ergebnisse in Bezug auf die Erwartungen der Patienten dar. Es bestehen mehrere Faktoren, die Einfluss auf die Behandlung nehmen können. Einer der Faktoren ist die Zusammenarbeit der Patienten (Compliance and Andherence), wobei die deklarative Einstellung gegenüber einer Therapie bisher selten untersucht worden ist. Ziel der Arbeit war es, zu untersuchen, welche Einstellung die Patienten gegenüber einer Chemotherapie und deren Nebenwirkungen vertreten und ob diese Einstellung als prognostischer Faktor für das Überleben gewertet werden kann. Methodik Es wurden die Daten einer abgeschlossenen randomisierten Phase-III-Studie bei NSCLC, sequenzielle Mono- vs. Zweifach- vs. Dreifachkombinationstherapie, analysiert. Insgesamt wurden zweihundertzweiundsiebzig Patienten im Alter zwischen vierunddreißig und fünfundsiebzig aus vierundzwanzig Kliniken aus Deutschland, die sich in Tumorstadium IIIb oder IV des NSCLC befanden, analysiert. Die Patienten sollten vor und nach der Therapie einen von der psychologischen Fakultät der Universität Marburg erstellten Fragebogen bezüglich ihrer Einstellung zur Chemotherapie ausfüllen. Unter anderem wurden dabei zehn Beispiele verschiedener Nebenwirkungen der Therapie benannt. Die Patienten wurden gebeten, anzugeben, wie (hoch oder niedrig) ihre Akzeptanz der Ne- benwirkungen in Abhängigkeit vom potenziellen Nutzen einer solchen Entscheidung wäre. Von den Studienteilnehmern wurde ein Patiententagebuch geführt, in dem Toxizitätskriterien, Symptome nach NCI-CTC und Laborparameter dokumentiert wurden. Zusätzlich wurden während der Studie Daten zur Lebensqualität nach EORTC erhoben. Ergebnisse Die überwiegende Mehrheit der Patienten war bereit, die Nebenwirkungen der Chemo- therapie zu ertragen. Die größten Bedenken stellten dabei Erbrechen, Hautausschläge und Taubheitsgefühle dar. Die Akzeptanz nahm mit dem potenziellen Gewinn der Therapie zu. Es wurde aber auch beobachtet, dass jene Patienten, die die Nebenwirkungen einer Therapie ablehnten, eine längere OS erreichten. Der Trend wurde in allen genannten Beispielen von Nebenwirkungen beschrieben. Statistisch relevant (Log-Rank p = 0,027) er- scheint das in der Abfrage der Einstellung zur Bluttransfusion, bei der das Gesamtüber- leben sogar anderthalb Mal länger ausfiel, als bei denjenigen, die diese Nebenwirkung nicht akzeptierten, auch wenn eine solche Chemotherapie potenziell zur Lebensverlängerung von einem Jahr geführt hätte (12,5 vs. 8 Monate). In der Arbeit konnte darüber hinaus beobachtet werden, dass neben den bekannten Faktoren wie dem Karnofsky-Index oder dem Vorhandensein von Metastasen auch die Entscheidung zur Bluttransfusion während des ersten Zyklus einen statistisch relevanten negativen prädiktiven Einfluss auf das Gesamtüberleben nahm (Log-Rank p = 0,005). 7.1.4 Diskussion Gemäß der Studie lag für die Patienten in der Lebensverlängerung, die auch auf Kosten mehrerer Nebenwirkungen gewünscht war, der wichtigste Faktor. Auf der anderen Seite zeigte sich eine negative Einstellung gegenüber Nebenwirkungen insbesondere bei Bluttransfusionen überraschend als positiver prognostischer Faktor für das Überleben. Es konnte keine Erklärung für diesen Trend gefunden werden. Es zeigt aber, dass die psychologische Einstellung gegenüber der Therapie eine unterschätzte Rolle im Therapieerfolg spielen dürfte. In der Arbeit konnte darüber hinaus beobachtet werden, dass Bluttransfusion schon während des ersten Chemotherapie-Zyklus als negativer Prognosefaktor zu werten ist. Um zu beantworten, ob diese Beobachtungen auch klinisch relevant sind, müssten allerdings weitere Untersuchungen in diesem Bereich durchgeführt werden.

eep learning algorithms have become the first choice as an approach to medical image analysis, face recognition, and emotion recognition. In this survey, several deep-learning-based approaches applied to breast cancer, cervical cancer, brain tumor, colon and lung cancers are studied and reviewed. Deep learning has been applied in almost all of the imaging modalities used for cervical and breast cancers and MRIs for the brain tumor. The result of the review process indicated that deep learning methods have achieved state-of-the-art in tumor detection, segmentation, feature extraction and classification. As presented in this paper, the deep learning approaches were used in three different modes that include training from scratch, transfer learning through freezing some layers of the deep learning network and modifying the architecture to reduce the number of parameters existing in the network. Moreover, the application of deep learning to imaging devices for the detection of various cancer cases has been studied by researchers affiliated to academic and medical institutes in economically developed countries; while, the study has not had much attention in Africa despite the dramatic soar of cancer risks in the continent., publishedVersion

Die Expression des KCa3.1-Kanals im Lungenkrebs beeinflusst die Prognose. Ferner wird die Extravasation von Lungenkrebszellen durch Kanalblockade ICAM-1-abhängig reduziert. Es wurde die Hypothese aufgestellt, dass KCa3.1-Kanäle auch in den Mitochondrien von Lungenkarzinom- und Endothelzellen exprimiert werden. Durch Kanalinhibition wird demnach das mitochondriale Membranpotenzial (MMP) hyperpolarisiert, die ROS-Produktion gesteigert, und vermehrt ICAM-1 an den Zelloberflächen präsentiert. Mittels Western Blot und Immunfluoreszenz konnte in dieser Arbeit die Expression von mitoKCa3.1-Kanälen in zwei Lungenkrebszelllinien aufgewiesen, und für eine Endothelzelllinie nahegelegt werden. Durch den KCa3.1-Inhibitor TRAM-34 wurde in Lungenkrebszellen eine Hyperpolarisation des MMP hervorgerufen. Das Vorkommen funktionaler KCa3.1-Kanäle in lungenkarzinomatösen Mitochondrien steht im Einklang mit der Hypothese. Dieser Kanal könnte zukünftig also in der Krebstherapie anvisiert werden.

Hintergrund und Ziele: Der Stellenwert der Lebensqualität ist heute in Hinblick auf das ständig erweiterte Therapiespektrum und die daraus resultierende verlängerte Überlebenszeit der Patienten durch effizientere Behandlungsmöglichkeiten so groß wie nie zuvor. Lebensqualität fließt als zentraler Punkt in die Bewertung von Therapien bei onkologischen Patienten mit ein. Hintergrund der Arbeit ist eine internationale Studie zur Aktualisierung des lungenkrebsspezifischen EORTC-Fragebogenmoduls QLQ-LC13, das bereits seit 20 Jahren der Erfassung der Lebensqualität von Lungenkrebspatienten dient. Nach dem EORTC Module Development Manual wird der Kernfragebogen EORTC QLQ-LC13 in einem 4-stufigen-Prozess dem aktuellen Stand in Diagnostik und Therapie angepasst. Bei dieser Arbeit handelt es sich um eine Teiluntersuchung der internationalen Phase 4 Studie zur Testung der psychometrischen Eigenschaften des neu zusammengestellten EORTC QLQ-LC29 Fragebogens. Hauptziel der vorliegenden Studie ist es, das Hornheider Screening-Instrument und die EORTC Fragebögen gleichzeitig einzusetzen und deren Gemeinsamkeiten und Unterschiede zu untersuchen. Methodik: In dieser Teilstudie der prospektiven klinischen Multicenterstudie wurden 81 Patienten mit histologisch gesichertem Bronchialkarzinom rekrutiert, welche sich in Behandlung am Universitätsklinikum Regensburg oder im Krankenhaus der Barmherzigen Brüder Regensburg befanden. Für die Befragung wurden dabei der Kernfragebogen EORTC QLQ-C30, das aktualisierte Modul QLQ-LC29 sowie das Hornheider Screening-Instrument verwendet. Die Lebensqualitätsfragebögen wurden anschließend ausgewertet und mit den Ergebnissen des Hornheider-Screening-Instruments verglichen. Die Studie wurde von der Ethikkommission der Universität Regensburg genehmigt (Bearbeitungsnummer 16-101-0059). Ergebnisse: 39 Patienten (48,1%) gelten laut HSI als betreuungsbedürftig bzw. als psychosozial belastet. Die höchste Korrelation der beiden Messinstrumente ergibt sich zwischen HSI und der EORTC-Skala „emotionale Funktion“, r=-0,591, p, Background: Although, overall survival is the ultimate criterion for an oncological therapy, quality of life becomes a more and more important issue in the treatment of lung cancer. The current report is based on a satellite project within a prospective, international, cross-cultural, multicenter study to validate the EORTC QLQ-LC29, a new designed module to assess the quality of life of lung cancer patients. The goal of the present project was to administer the Hornheide Screening Instrument (HSI) and the EORTC QLQ-C30/-LC29 in a sample of lung cancer patients in order to analyze agreements and possible differences between the instruments. Method: The study recruitment for this satellite project took place from April 2016 to April 2017 and 81 patients with diagnosed lung cancer were recruited in the University Hospital Regensburg and the hospital Barmherzige Brüder in Regensburg. Patients were asked to fill in the EORTC QLQ-C30 questionnaire, the recently updated lung cancer module QLQ-LC29 and the Hornheide Screening Instrument. The instruments were analyzed and compared to each other. Approval from the Ethical Committee of the University Regensburg was obtained (reference number 16-101-0059). Results: According to the HSI, 39 patients (48,1%) needed psychosocial support. The most prominent correlation between the EORTC and the Hornheide Screening Instrument was found in “emotional function” (r=0,591, p

BackgroundCancer is characterized by an accumulation of somatic mutations, of which a significant subset can generate cancer-specific neoepitopes that are recognized by autologous T cells. Such neoepitopes are emerging as important targets for cancer immunotherapy, including personalized cancer vaccination strategies.MethodsWe used whole-exome and RNA sequencing analysis to identify potential neoantigens for a patient with non-small cell lung cancer. Thereafter, we assessed the autologous T-cell reactivity to the candidate neoantigens using a long peptide approach in a cultured interferon gamma ELISpot and tracked the neoantigen-specific T-cells in the tumor by T-cell receptor (TCR) sequencing. In parallel, identified gene variants were incorporated into a Modified Vaccinia Ankara-based vaccine, which was evaluated in the human leucocyte antigen A*0201 transgenic mouse model (HHD).ResultsSequencing revealed a tumor with a low mutational burden: 2219 sequence variants were identified from the primary tumor, of which 23 were expressed in the transcriptome, involving 18 gene products. We could demonstrate spontaneous T-cell responses to 5/18 (28%) mutated gene variants, and further analysis of the TCR repertoire of neoantigen-specific CD4+ and CD8+ T cells revealed TCR clonotypes that were expanded in both blood and tumor tissue. Following vaccination of HHD mice, de novo T-cell responses were generated to 4/18 (22%) mutated gene variants; T cells reactive against two variants were also evident in the autologous setting. Subsequently, we determined the major histocompatibility complex restriction of the T-cell responses and used in silico prediction tools to determine the likely neoepitopes.ConclusionsOur study demonstrates the feasibility of efficiently identifying tumor-specific neoantigens that can be targeted by vaccination in tumors with a low mutational burden, promising successful clinical exploitation, with trials currently underway., publishedVersion
