Palliative care in lung cancer: tumour- and treatment-related complications in lung cancer and their management.

Palliative care pertains to the holistic multidimensional concept of "patient-centred" care. It is an interprofessional specialty, primarily aiming to improve quality of care for cancer patients and their families, from the time of diagnosis of malignant disease, over the continuum of cancer care, and extending after the patient's death to the period of bereavement to support the patient's family. There are various complex and frequently unmet needs of lung cancer patients and their families/caregivers, not only physical but also psychological, social, spiritual and cultural.

Different approach to M descriptor for future staging of oligometastatic disease in SCLC: A cross-sectional survival analysis.

Purpose: This study aimed to investigate the impact of oligometastasis and the M descriptor on survival in small cell lung cancer (SCLC).

Methods: This multicenter, retrospective study included patients with newly diagnosed extensive-stage SCLC(ES-SCLC) from 2010 to 2020. Subgroups: Group 1: single metastasis in a single organ, Group 2: 2-5 metastases in a single organ, Group 3: 6 or more metastases in a single organ, and Group 4: metastases in two or more organs.

Potential role of pre-treatment bone marrow SUVmean to liver SUVmean ratio (BM/L) and comparison of primary tumour FDG uptake with brain FDG uptake in predicting survival in limited-stage lung cancers.

Introduction: The survival rates of patients with limited-stage small-cell lung cancer are low despite curative treatment. Accordingly, we investigated the disease prognosis by comparing the pre-treatment bone marrow mean standardised uptake values (SUVmean) / liver SUVmean ratio (BM/L) and primary tumour FDG uptake and brain FDG uptake to prognosis.

Materials And Methods: This was an observational, retrospective, single-centre study of patients with limited-stage small-cell lung cancer.

Could PD-L1 positivity be associated with venous thrombosis in patients with non-small cell lung cancer?

The risk of venous thromboembolism (VTE) is increased in non-small cell lung cancer (NSCLC), and defining at-risk patients is important. Thus, we aimed to assess the association between programmed cell death ligand 1 (PD-L1) expression and VTE [pulmonary embolism (PE), deep venous thrombosis (DVT)] in NSCLC. In this retrospective, observational multicentre study, 369 patients with NSCLC who had PD-L1 immunohistochemistry based on biopsies taken between January 2017 and December 2019, were divided as PD-L1-positive (n = 181) and -negative (n = 188) groups, and low-positive (n = 99) and high-positive (n = 82) PD-L1 groups.

Evaluation of Exudative Pleural Effusions: A Multicenter, Prospective, Observational Study.

Purpose: The aim of this study is to determine the diagnostic performances of pleural procedures in undiagnosed exudative pleural effusions and to evaluate factors suggestive of benign or malignant pleural effusions in tertiary care centers.

Methods: This was a multicenter prospective observational study conducted between January 1 and December 31, 2018. A total of 777 patients with undiagnosed exudative pleural effusion after the initial work-up were evaluated.

The efficacy of F-FDG PET/CT in monitoring disease progression in malignant pleural mesothelioma.

Objective: In the event of suspicion of malignant pleural mesothelioma (MPM) progression, imaging plays an important role. We aimed to evaluate the efficacy of F-FDG PET/CT in monitoring disease progression by comparing it with CT, and estimate median overall survival (OS) according to progression status with CT and F-FDG PET/CT.

Materials And Methods: This was an observational, retrospective, single-institution study with MPM patients who had both F-FDG PET/CT and CT for monitoring disease progression from March 2009 to February 2020.

Characteristics of our hypoxemic COVID-19 pneumonia patients receiving corticosteroids and mortality-associated factors.

Background: COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia.

Clinical management of lung cancer patients with respiratory symptoms during the COVID-19 pandemic.

Objective: There are many clinical conditions, such as lung cancer, that need to be followed up and treated during a pandemic. Providing health care for patients who are immune-suppressive requires extra care.

Method: Among 108 lung cancer patients who had been hospitalized during the COVID-19 pandemic, 18 with respiratory symptoms were evaluated retrospectively.

The success of non-invasive mechanical ventilation in lung cancer patients with respiratory failure.

Introduction And Aim: Despite the improvement in survival among patients with lung cancer as a result of the development of novel treatment options, acute respiratory failure (ARF), which may occur because of the disease itself, comorbidities or complications in treatment may be life threatening. The most commonly utilised treatment option in cancer patients with ARF is invasive mechanical ventilation (IMV). The prognosis of lung cancer patients admitted to the intensive care unit is poor.

Comparing effectiveness of intelligent volume-assured pressure support (iVAPS) vs bi-level positive airway pressure spontaneous/timed (BPAP S/T) for hypercapnic respiratory failure in chronic obstructive pulmonary disease.

Background And Aim: Intelligent volume-assured pressure support (iVAPS) is a relatively new hybrid mode of non-invasive ventilation (NIV). There is still limited evidence for iVAPS. The aim of this study was to compare the effectiveness of iVAPS to that of bi-level positive airway pressure spontaneous/timed (BPAP S/T) in patients with acute hypercapnic respiratory failure or acute-on-chronic hypercapnic respiratory failure caused by acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the emergency department.

Association of depression with improper use of inhaler devices by patients with obstructive disease.

Introduction: Obstructive pulmonary disease may cause some psychiatric disorders such as depression, similar to other chronic diseases. Patients with chronic obstructive pulmonary disease or asthma are especially susceptible to inhaler technique errors. The aim of this study was to evaluate the depression that can affect improper use of inhaler devices and to show the contribution of age, sex, and education to correct usage.

Effect of Asbestos Exposure on the Frequency of EGFR Mutations and ALK/ROS1 Rearrangements in Patients With Lung Adenocarcinoma: A Multicentric Study.

Objective: The aim of this study is to investigate the effect of asbestos exposure on cancer-driver mutations.

Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded.

Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.

The Clinical Impact of Re-biopsies in Lung Adenocarcinoma: a Retrospective Multicenter Study.

If a patient's cancer progresses while undergoing targeted therapy, a re-biopsy is not mandatory. But when evaluating the benefits and risks on a case-by-case basis (transformation to small cell, assessing for a clinical trial), physicians should inform patients about the possible need for a re-biopsy (5). This was a retrospective and multicentre study.

Treatment outcomes in oligometastatic non-small-cell lung cancer: A single-centre experience.

Background: Even in oligometastatic stage 4 disease, survival rates are higher when curative approaches focus on both the primary tumour and metastasis. So, we aim to analyse our results of oligometastatic disease retrospectively.

Methods: In total, data on 52 non-small-cell lung cancer (NSCLC) patients with limited metastasis (one to three synchronous/metachronous) were retrospectively analysed.

Prognostic significance of preoperative consolidation to maximum tumour diameter ratio and SUVmax in pathological stage I lung adenocarcinoma.

Objectives: Consolidation/tumour (C/T) ratio means the maximum diameter of the consolidation is divided by the maximum diameter of the tumour and it is predictive for pathologic subtypes and prognosis after resection of the tumour. The purpose of this study is to clarify impact of C/T ratio along with maximum standardized uptake value (SUV) in pathological stage I lung adenocarcinoma.

Methods: Only patients with pathological stage I lung adenocarcinoma diagnosed by resection were included.

High serum YKL-40 level is associated with poor prognosis in patients with lung cancer.

Introduction: YKL-40 is a glycoprotein that plays role in inflammation and malignant processes. High serum YKL-40 levels are associated with short survive in cancer and chronic obstructive pulmonary disease (COPD) is another reason to increase its' level. However, limited knowledges are known in YKL-40 along with lung cancer and COPD.

Frequency of vitamin K oxidoreductase complex subunit-1 (VKORC1) polymorphisms and warfarin dose management in patients with venous thromboembolism.

Warfarin works by inhibiting VKORC1, so polymorphisms of this gene modify the required drug dose. The aim of this study is to examine the relation between therapeutic weekly dose of warfarin and C1173T/G1639A polymorphism of VKORC1 in patients with VTE. Seventy-five patients with VTE were enrolled.

Severe Pneumonia Treated Succesfully with Levofloxacin and Oseltamivir During Flu Epidemic.

Viral pneumonia is an important cause of community acquired pneumonias (CAP). It's not only specific to childhood period. Although immunocompromised adults are susceptible; all young and healthy adults are at risk.

Prognostic significance of serum vascular endothelial growth factor and Angiopoietin-2 in patients with lung cancer.

Introduction: Vascular endothelial growth factor (VEGF) and Angiopoietin-2 (Ang-2) are major angiogenic mediators in neovascularization process. In current literature both biomarkers are discussed separately and only for non-small cell lung cancer (NSCLC). So in this study we aimed to examine them together for both cell types NSCLC and small cell lung cancer (SCLC).

Pulmonary alveolar proteinosis and successful therapy with combined lavage procedures: Case reports.

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the accumulation of lipoproteinaceous material within alveolar spaces. Whole-lung lavage (WLL) has been the most common therapeutic intervention for this disorder. However, patients presenting with PAP are usually hypoxemic or in poor clinical condition, and WLL may be impossible to perform.

[Early use of noninvasive mechanical ventilation in patients with acute hypercapnic respiratory failure in a respiratory ward: a prospective study].

Background: In recent years, the optimal location for noninvasive mechanical ventilation (NIMV) has been a matter of debate. Our aim was to detect the effectiveness of NIMV in acute hypercapnic respiratory failure (AHRF) in respiratory ward and factors associated with failure.

Methods: 69 patients treated with NIMV in respiratory ward were prospectively evaluated.
