Background/aim: Cemiplimab in patients with non-small cell lung cancer (NSCLC) with PD-L1 (programmed death ligand type 1) expression ≥50% showed a significant improved overall survival (OS) with increasing expression of PD-L1. To our knowledge there exist no similar data published for pembrolizumab regarding the increased OS in relation to the PD...

Background: Stage III non-small cell lung cancer (NSCLC) is a highly heterogeneous stage due to its subgroups (IIIA-IIIC) comprising both resectable and unresectable tumors. Accurate determination of the extent of the disease is essential for excluding stage IV and choosing the optimal treatment regimen. Whole body positron emission tomography and...

Purpose The aim of our study was to evaluate if therapeutic success in the first-line of anticancer treatments in patients with NSCLC may predict treatment success in the following lines. Methods We analyzed the data of patients with NSCLC stage III/IV from the TULUNG registry separately for chemotherapy, TKIs, ALK inhibitors, and immunotherapy in...

Background/aim: The aim of this study was to investigate possible association between adverse events of nivolumab therapy and the effectiveness of treatment in patients with non-small cell lung cancer (NSCLC). Focusing on serious adverse events (i.e., those of grade ≥3), we evaluated overall survival (OS), progression-free survival (PFS), as well...

Background: Programmed death-ligand 1 (PD-L1) expression is a standard predictor in the selection of immunotherapy for locally advanced/advanced non-small cell lung cancer (NSCLC). However, comedication with corticosteroids or non-steroidal anti-inflammatory drugs (NSAIDs) may influence the effectiveness of this treatment as documented in several...

Aim: This study compared the results of nivolumab treatment in patients with pulmonary adenocarcinomas based upon previous chemotherapeutic regimens. Patients and methods: The data source for this retrospective study was the Czech VILP registry of patients with nivolumab-treated adenocarcinomas in second and higher lines of treatment. In relatio...

Background/aim: This study aimed at contributing to a better diagnosis of lung cancer by analyzing the patient's symptoms and their linkage to other characteristics. Patients and methods: We analyzed the data of 3,322 patients from LUCAS (LUngCAncerfocuS) National Registry of the Czech Republic. Overall survival was assessed using the Kaplan-Mei...

Background/aim: Due to some interconnectedness at the molecular level, this study assessed the possible influence of laboratory parameters associated with systemic inflammatory environment on programmed death-ligand 1 (PD-L1) expression in non-small cell lung carcinoma (NSCLC). Patients and methods: We assessed effects of c-reactive protein (CRP...

Background/aim: LUCAS is a clinical lung cancer registry (ClinicalTrials.gov identifier is NCT04228237), prospectively collecting data from newly diagnosed lung cancer patients in seven pneumooncology centers in the Czech Republic, since June 1, 2018. The aim of the study was to assess the stage of the disease at the time of diagnosis, percentage...

Background/aim: Per literature, patients with epidermal growth factor receptor (EGFR) exon-20 insertions respond poorly to tyrosine kinase inhibitors (TKIs). This study analyzed real-world data to examine the prognostic and predictive value of these mutations. Patients and methods: We conducted a retrospective cohort study using Czech TULUNG Reg...

Background/aim: Platinum-based chemotherapy with pemetrexed or paclitaxel/bevacizumab are regimens used in combination with checkpoint inhibitors in non-squamous non-small cell lung cancer (NSCLC) treatment. We conducted a real-world study to compare the outcomes of these chemotherapeutic regimens. Patients and methods: We investigated 1,534 pat...

Background/aim: We investigated efficacy differences for afatinib versus gefitinib in non-small-cell lung cancer (NSCLC) according to epidermal growth factor receptor (EGFR) mutations. Patients and methods: We retrospectively analysed data for 343 patients with NSCLC with performance status 1 having EGFR mutations treated with gefitinib or afati...

Background Data regarding real‐life effectiveness of any treatment may improve clinical decision‐making. The aim of this study was to evaluate real‐life effectiveness of tyrosin‐kinase inhibitors, bevacizumab and pemetrexed as first‐line treatments in patients with advanced/metastatic non‐small cell lung cancer (NSCLC). Methods We analyzed data of...

Aim: To investigate potential association between administration of corticosteroids, antibiotics, probiotics, proton pump inhibitors, non-steroidal anti-inflammatory drugs (NSAID), statins and metformin and outcome in patients with non-small cell lung cancer (NSCLC) treated with nivolumab. Patients and methods: A total of 224 patients with advan...

Aim: To compare survival outcomes in patients with non-small cell lung cancer (NSCLC) treated with modern-era drugs (antifolates, antiangiogenics, tyrosine kinase and anaplastic lymphoma kinase inhibitors, immunotherapy) with treatment initiation in 2011-12 and 2015-16, respectively. Patients and methods: Prospective data from Czech TULUNG Regis...

Aim: To investigate potential associations between clinical and standard peripheral blood biomarkers and clinical outcome in patients with non-small cell lung cancer (NSCLC) treated with nivolumab. Patients and Methods: A total of 120 patients with advanced NSCLC treated at seven comprehensive cancer care centers were analyzed in this national retr...

Background: Patients with advanced anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) may gain significant benefit from treatment with the first-generation ALK inhibitor crizotinib. This study investigated the effects of crizotinib in advanced ALK-positive NSCLC patients via analyzing data submitted to the TULUNG registr...

Lung cancer is the leading cause of cancer-related mortality in the world. Chemotherapy has been the mainstay of treatment for advanced non-small cell lung cancer (NSCLC) and platinum-based derivatives have been shown to improve overall survival. The aim of the present study was to investigate the DNA damage [single strand breaks (SSBs) and DNA cro...

Erlotinib is an epidermal growth factor receptor tyrosine-kinase inhibitor. Clinical trials have shown its efficacy in advanced non-small cell lung cancer (NSCLC). We conducted a large retrospective study based on clinical experience aiming to prove erlotinib's efficacy and safety in patients with advanced-stage squamous cell NSCLC. Totally 375 pat...

Associations between nasal and bronchial impairment have been repeatedly described in chronic obstructive pulmonary disease (COPD), whereas nasal mucociliary clearance (MCC) in COPD patients is not yet fully understood. We studied nasal MCC parameters in COPD patients and compared them with healthy adults (HA) and with cystic fibrosis (CF) patients...

Spiritual life of the elderly patients is very important, but in practice the medical staff hardly thinks about the spiritual needs. According to foreign studies, a lively faith has a positive curative effect. The aim of our work was the evaluation of the influence of faith to the survival of illness in the elderly and the description of spiritual...
