The process of implementing early detection of lung cancer with low-dose CT (LDCT) in Germany has gained significant momentum in recent years. It is expected that the ordinance of the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) on the early detection of lung cancer, which has been commented on by the professional societies, will come into effect by the end of 2023. Based on this regulation, the Federal Joint Committee (G-BA) will set up a program for early lung cancer detection with LDCT in the near future. In this position paper, the specialist societies involved in lung cancer screening present key points for a uniform, structured and quality-assured early detection program for lung cancer in Germany to make a constructive contribution to this process.

Positron emission tomography - Computed tomography for staging of mediastinal lymph nodes in patients with non-small cell lung cancer.

Background: The tumor involvement of lymph nodes (LN) in N2 station is a very important factor for the further therapy decision and the prognosis of lung cancer patients. Today, integrated positron emission tomography-computed tomography (PET-CT) is considered to be the new standard in the staging of bronchial carcinoma. The aim of this study is to investigate the correctness of the clinical staging of the mediastinal LNs in operated patients and to investigate the sensitivity and specificity of the PET-CT examination for mediastinal LNs. Subjects and Methods: In the years 2010-2014, 359 patients underwent surgery for bronchial carcinoma. The histological examination of all mediastinal and hilar LNs was used as a reference to the data from the PET-CT examinations. The correctness of the PET staging, overestimation, and underestimation for the N stage was analyzed. In addition, the "sensitivity," "specificity," and "overall accuracy" of the PET-CT examination with regard to the N2 LNs were calculated. Results: It was found that in 8.9% the staging of the mediastinal N2/N3 LN stations was rated too high by the PET and in 11.2% too low. The study showed a sensitivity of 47.37%, a specificity of 90.07%, and an accuracy of 81.01% for the mediastinal LNs. Conclusion: Our study confirms the limited ability of integrated PET-CT in staging the mediastinal LNs. We, therefore, recommend a histological examination of the LNs in patients with PET-positive N2 LNs to avoid false-positive results and to initiate correct therapy.

Résumé Contexte: L'implication tumorale des ganglions lymphatiques (LN) au stade N2 est un facteur très important pour la décision thérapeutique ultérieure et le pronostic des patients atteints de cancer du poumon. Aujourd'hui, la tomographie par émission de positons intégrée (TEP-CT) est considérée comme être la nouvelle norme dans la stadification du carcinome bronchique. Le but de cette étude est d'étudier l'exactitude de la stadification clinique des ganglions lymphatiques médiastinaux chez les patients opérés et d'étudier la sensibilité et la spécificité de l'examen TEP-TDM pour les ganglions lymphatiques médiastinaux. Sujets et méthodes: Dans les années 2010 à 2014, 359 patients ont été opérés d'un carcinome bronchique. L'examen histologique de tous les LN médiastinaux et hilaires a servi de référence aux données des examens PET-CT. La justesse de la mise en scène PET, la surestimation et la sous-estimation pour le stade N ont été analysées. De plus, la " sensibilité ", la " spécificité " et la " précision globale " de l'examen PET-CT en ce qui concerne les N2 LNs ont été calculés. Résultats: Il a été constaté que dans 8,9 % des cas, la mise en scène du médiastin N2/ Les stages N3 LN ont été jugées trop élevées par le PET et dans 11,2 % trop faibles. L'étude a montré une sensibilité de 47,37%, une spécificité de 90,07%, et une précision de 81,01 % pour les LN médiastinaux. Conclusion: Notre étude confirme la capacité limitée de la TEP-TDM intégrée dans la stadification les LN médiastinaux. Nous recommandons donc un examen histologique des ganglions lymphatiques chez les patients avec des ganglions lymphatiques N2 positifs à la TEP pour éviter résultats faussement positifs et d'initier un traitement correct Mots-clés: Cancer du poumon, tomographie par émission de positrons/tomodensitométrie, stadification.

[Monstrous Solitary Fibrous Tumor of the Pleura - A Case Report and Review of the Literature]. / Monströser solitärer fibröser Tumor der Pleura.

Localized solitary fibrous tumors are a rare entity and are mostly found in the thorax, but can also occur in the liver, skin, meninges, peritoneum, and pericardium. Making the diagnosis is often difficult because of the various micromorphologic outlooks. The histopathological assessment with differentiated immunohistochemistry is decisive. Surgical resection of the localized solitary fibrous tumors is the therapy of choice. The recurrence and metastasis rates depend on the histological dignity and are in total very low. Therefore, continuous follow-up examinations are indicated. We report on a 76-year-old female patient with a monstrous solitary fibrous tumor of the pleura who complained of exertional dyspnea and sharp pain in the right thoracic region for several weeks. Computed tomography showed a massive, heterogeneous pulmonary mass 22 cm in diameter in the middle and lower field of the right lung with compression of the diaphragm and mediastinum. The tumor was completely resected through a double thoracotomy in the 5th and 8th ICR. Intraoperatively, the tumor was stalked to the middle lobe. In order to completely remove the tumor, a wedge resection was also performed from the middle lobe. The tumor weighed 2.4 kg. The diagnosis of a solitary fibrous tumor of the pleura was made histologically and immunohistochemically. Postoperatively, the lung has fully expanded. There was no evidence of a relapse at the 3-month follow-up examination. The clinical symptoms, diagnosis, treatment options, risk of recurrence and the prognosis of these tumors are shown and discussed in accordance with the literature.

[Health-Related Quality of Life in Patients with Non-Small Cell Lung Cancer before and after Surgery - a Comparison between Thoracotomy and Video-Assisted Thoracoscopic Surgery]. / Untersuchungen zum Verlauf der Lebensqualität vor und bis 2 Jahre nach anatomischer Resektion bei Patienten mit Lungenkarzinom ­ ein Vergleich zwischen anterolateraler Thorakotomie und videoassistierter Thorakoskopie.

BACKGROUND: Earlier studies have proven that in patients with non-small cell lung cancer video-assisted thoracoscopic surgery is functionally superior to thoracotomy in terms of perioperative and postoperative complications. The objective of this work was to determine whether there is a difference in health-related quality of life (HRQoL) of patients with non-small cell lung cancer - compared to the German normal population - before and after surgery. Moreover, HRQoL after thoracotomy was compared to HRQoL after video-assisted thoracoscopic surgery (VATS). MATERIAL AND METHODS: Based on retrospective data generated during a 7-year period (2010 - 2017), 327 patients with non-small cell lung cancer who underwent therapy were examined. Patients either underwent thoracotomy or video-assisted thoracoscopic surgery. 456 of short form 12 questionnaires were analysed. Via norm-based scoring, and physical and mental component summaries (PCS and MCS) were calculated before and 6, 12, and 24 months after treatment. Using t tests, potential differences in physical and mental component summaries were evaluated between patients and the German normal population as well as between patients after thoractomy and after VATS. RESULTS: Up to 24 months after surgery, the physical dimension of HRQoL is significantly reduced, while the mental component summary does not significantly differ from the German population. Moreover, thoracotomy and VATS gave equivalent values for health-related quality of life. CONCLUSION: With respect to health-related quality of life, thoracotomy and video-assisted thorascopic surgery are equivalent in the long term. But there was a trend to improvement with both summary scores that might indicate superiority of video-assisted thoracoscopic surgery.

[Pain Treatment After Thoracic Surgery]. / Schmerztherapie nach thoraxchirurgischen Eingriffen.

The treatment of pain after thoracic surgery is a challenge and takes place in the individual clinics mostly according to clinic internal standards. It exists no currently valid S3 guideline for the treatment of acute perioperative and posttraumatic pain. For an effective pain treatment as well individual pain experience as the pain intensity of the various thoracic surgical procedures must be considered. Regular pain assessment with appropriate methods and their documentation form the basis for adequate and adapted pain therapy.There are a number of different pain therapy methods, non-medicamentous and drug-based methods, whose effectiveness is described in the literature partially different. For the treatment of acute postoperative pain after thoracic surgery, mainly drug-related procedures are used, except for physiotherapy as a non-medicamentous method. Increasingly, alternative procedures for the peridural catheter as a therapeutic gold standard in the treatment of pain after thoracic surgery are used. Their application can be integrated into a therapeutic algorithm.

Nurses' knowledge of care of chest drain: A survey in a Nigerian semiurban university hospital.

BACKGROUND/OBJECTIVE: Inefficient nursing care of chest drains may associated with unacceptable and sometimes life-threatening complications. This report aims to ascertain the level of knowledge of care of chest drains among nurses working in wards in a teaching hospital in Nigeria. METHODS: A cross-sectional study among nurses at teaching hospital using pretested self-administered questionnaires. RESULTS: The majority were respondents aged between 31 and 40 years (45.4%) and those who have nursing experience between 6 and 10 years. Only 37 respondents (26.2%) had a good knowledge of nursing care of chest drains. Knowledge was relatively higher among nurses who cared for chest drains daily, nurses who have a work experience of <10 years, low-rank nurses and those working in the female medical ward; however, the relationship were not statistically significant (P > 0.05). Performance was poor on the questions on position of drainage system were not statistically significant with relationship to waist level while mobilizing the patient, application of suction to chest drains, daily changing of dressing over chest drain insertion site, milking of tubes and drainage system with dependent loop. CONCLUSION: The knowledge of care of chest drains among nurses is poor, especially in the key post procedural care. There is an urgent need to train them so as to improve the nursing care of patients managed with chest drains.

Cerebral infarct complicating traumatic pneumatocele: a rare sequela following blunt chest trauma.

Systemic air embolism is known to rarely complicate blunt chest trauma. However, cerebral infarction caused by air emboli possibly originating from a traumatic pneumatocele has not been previously reported. We report a case of a 46-year-old woman who sustained blunt chest trauma with multiple rib and clavicular fractures, hemothorax and a huge, tense traumatic pneumatocele. She subsequently developed clinical and radiologic features of cerebral infarction. The cerebral infarct is likely to be secondary to cerebral air embolism originating from a traumatic pneumatocele.

Ergonomics in thoracoscopic surgery: results of a survey among thoracic surgeons.

OBJECTIVES: The frequent and prolonged use of thoracoscopic equipment raises ergonomic risks which may cause physical distress. We aimed to determine the relationship between ergonomic problems encountered in thoracoscopic surgery and physical distress among thoracic surgeons. METHODS: An online questionnaire which investigated personal factors, product factors, interaction factors and physical discomfort was sent to all members of the European Society of Thoracic Surgeons (ESTS). RESULTS: Of the respondents, 2.4% indicated that a one arm's length should be the optimal distance between the surgeon and the monitor. Only 2.4% indicated that the monitor should be positioned below the eye level of the surgeon. Most of the respondents agreed, partially to fully, that they experienced neck discomfort because of inappropriate monitor height, bad monitor position and bad table height. Most respondents experienced numb fingers and shoulder discomfort due to instrument manipulation. Most of the respondents (77.1%) experienced muscle fatigue to some extent due to a static posture during thoracoscopic surgery. The majority of respondents (81.9, 76.3 and 83.2% respectively) indicated that they had varying degrees of discomfort mainly in the neck, shoulder and back. Some 94.4% of respondents were unaware of any guidelines concerning table height, monitor and instrument placement for endoscopic surgery. CONCLUSIONS: Most thoracic surgeons in Europe are unaware of ergonomic guidelines and do not practise them, hence they suffer varying degrees of physical discomfort arising from ergonomic issues.

Pyothorax-associated lymphoma (PAL): report and review of a rare entity.

Pyothorax-associated lymphoma (PAL) is a rare haematological malignancy often associated with artificial pneumothorax due to the treatment of pulmonary tuberculosis. A 76 year old man with chronic tube-drained pyothorax and a history of artificial pneumothorax for pulmonary tuberculosis was admitted to our hospital because of progressive right thoracic pain, weight loss, and pyrexia. After clinical examination and imaging processes a chest wall tumour anterior on the right side was diagnosed as well as a persisting pyothorax. Surgery was performed to resect the tumour and drain the pleural cavity. A diagnosis of a high grade B-cell lymphoma was established after histological examination of the surgical biopsy. Epstein-Barr virus (EBV) was identified in the tumour by immunocytochemical and molecular methods. Additional gastric involvement of B-cell lymphoma could be diagnosed by gastroscopy because of postoperative gastrointestinal bleeding. The patient received chemotherapy with 2 courses of cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP). The response was favourable initially, but 2 months later the patient died because of lymphoma progression.Most cases of PAL have been described by Japanese investigators and only a few cases are reported in Western countries. To the best of our knowledge this case of PAL is the first to be documented in Germany.Awareness of this rare entity, together with diligent histological examination, in patients with chronic pyothorax are essential for a correct diagnosis and correct early treatment.

Surgery and adjuvant therapy in patients with diffuse peritonitis: cost analysis.

In a prospective, randomized, controlled trial the effect of high dose intravenous antithrombin III and intraabdominal donor serum was analyzed in 36 patients with diffuse secondary peritonitis. The direct cost for treatment was 25,370 euros per patient, and the post acute hospital care costs and societal costs were 6273 euros. The cost for intensive care of these patients accounted for approximately 83% of the direct costs, while the expenditures for operating theater and general wards accounted for 9% each. The most expensive factors were staff, medication, and blood products. The hospital incurred a deficit of 3696 euros for each patient after reimbursement from public health insurance companies. Quality of life as assessed by the gastrointestinal quality of life index (GIQI) showed a good outcome. On average 11 quality adjusted life years (QALY) were achieved. The cost per QALY was 2631 euros. Use of adjuvant therapy was associated with a reduced duration of intensive care unit (ICU) treatment, times on mechanical respiration, and hemofiltration; the cost of treatment was reduced by 6614 euros per patient. The additional cost of antithrombin III (5155 euros) was more than offset by the savings made when adjuvant therapy was used.
