Afatinib as first-line treatment in patients with -mutated non-small cell lung cancer in routine clinical practice.

Background: Lung cancer is a leading cause of cancer-related death in Germany and worldwide. Non-small cell lung cancer (NSCLC) comprises ~80% of lung cancer diagnoses; in White patients, around 10% of NSCLC cases are epidermal growth factor receptor mutation-positive (m+). Head-to-head clinical trials have demonstrated superior efficacy with second-/third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) first-generation EGFR TKIs in m+ NSCLC.

Returning to work in lung cancer survivors-a multi-center cross-sectional study in Germany.

Purpose: To investigate the work situation of lung cancer survivors and to identify the factors associated with their returning to work.

Methods: Descriptive analysis and logistic regression were used to evaluate study population characteristics and independent factors of subsequently returning to work. To analyze time to return to work, Cox regression was used.

Use of psychosocial services by lung cancer survivors in Germany : Results of a German multicenter study (LARIS).

Purpose: Little is known about the use of psychosocial services in lung cancer survivors and patients who have survived the diagnosis for at least one year. We investigated the frequency of use, stratified by radiation therapy received, its associated factors, and the reasons for non-use of those services.

Methods: We performed a multicenter (n = 6 hospitals) cross-sectional study using data from medical records, patient reported questionnaires, and computer-assisted telephone interviews.

Impact of EMT in stage IIIB/IV NSCLC treated with erlotinib and bevacizumab when compared with cisplatin, gemcitabine and bevacizumab.

The aim of the present study was to assess the expression of epithelial-mesenchymal transition biomarkers (E-cadherin and vimentin) and their potential significance as prognostic markers in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC) enrolled in the INNOVATIONS trial, receiving treatment with either erlotinib/bevacizumab (EB) or cisplatin/gemcitabine/bevacizumab (PGB). The tumor tissues of 104 patients were retrospectively analyzed using immunohistochemistry to assess the expression of E-cadherin and vimentin. The distribution between the treatment arms was 46 patients in the EB-arm and 58 in the PGB-arm.

Quality of Life in NSCLC Survivors - A Multicenter Cross-Sectional Study.

Introduction: The objective was to assess quality of life (QoL) in lung cancer survivors, compare it to the general population, and identify factors associated with global QoL, physical functioning, emotional functioning, fatigue, pain, and dyspnea.

Methods: Data from NSCLC patients who had survived 1 year or longer after diagnosis were collected cross-sectionally in a multicenter study. QoL was assessed with the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and the lung cancer module QLQ-LC13 across different clinical subgroups and compared to age- and sex-standardized general population reference values.

ERCC1 assessment in upfront treatment with and without cisplatin-based chemotherapy in stage IIIB/IV non-squamous non-small cell lung cancer.

Prior studies have demonstrated an association between excision repair cross-complementation group 1 (ERCC1) expression level and outcomes in patients with advanced non-small cell lung cancer (NSCLC) treated with platinum-based chemotherapy. The aim of this study was to assess the impact of ERCC1 on survival for patients with stage IIIB/IV non-squamous NSCLC (NS-NSCLC) enrolled in the INNOVATIONS trial, thus receiving as treatment either erlotinib/bevacizumab (EB) or cisplatin/gemcitabine/bevacizumab (PGB). We retrospectively analyzed tumor tissue of 72 patients using immunohistochemistry to assess the expression of ERCC1.

65Plus: open-label study of bevacizumab in combination with pemetrexed or pemetrexed/carboplatin as first-line treatment of patients with advanced or recurrent nonsquamous non-small-cell lung cancer.

Background: The aim of the study was to investigate in terms of noninferiority the efficacy and safety of a monochemotherapy regimen of pemetrexed plus bevacizumab (BevPem) versus carboplatin/pemetrexed plus bevacizumab (BevCPem) in elderly patients as first-line treatment for advanced metastatic or recurrent nonsquamous non-small-cell lung cancer (NSCLC).

Materials And Methods: 65Plus was a Phase III, randomized, open-label study. In total, 253 patients received BevPem (n=119) or BevCPem (n=134).

Comprehensive Biomarker Analyses in Patients with Advanced or Metastatic Non-Small Cell Lung Cancer Prospectively Treated with the Polo-Like Kinase 1 Inhibitor BI2536.

Background: Polo like kinase 1 (PLK1) is frequently upregulated in tumors and is thus viewed as a promising therapeutic target in various cancers. Several PLK1 inhibitors have recently been developed and clinically tested in solid cancers, albeit with limited success. So far, no predictive biomarkers for PLK1 inhibitors have been established.

Erlotinib and bevacizumab versus cisplatin, gemcitabine and bevacizumab in unselected nonsquamous nonsmall cell lung cancer.

Erlotinib with bevacizumab showed promising activity in recurrent nonsquamous (NS) nonsmall cell lung cancer (NSCLC). The INNOVATIONS study was designed to assess in first-line treatment of unselected cisplatin-eligible patients this combination compared to cisplatin, gemcitabine and bevacizumab. Stage IIIB/IV patients with NS-NSCLC were randomised on erlotinib (150 mg daily) and bevacizumab (15 mg·kg(-1) on day 1, every 3 weeks) (EB) until progression, or cisplatin (80 mg·m(-2) on day 1, every 3 weeks) and gemcitabine (1250 mg·m(-2) on days 1 and 8, every 3 weeks) up to six cycles and bevacizumab (15 mg·kg(-1) on day 1, every 3 weeks) (PGB) until progression.

The gefitinib long-term responder (LTR)--a cancer stem-like cell story? Insights from molecular analyses of German long-term responders treated in the IRESSA expanded access program (EAP).

Background: In selected patients with advanced non-small cell lung cancer (NSCLC) the EGFR (epidermal growth factor receptor) tyrosine kinase inhibitor (TKI) gefitinib (IRESSA) shows response rates of ≥ 70% and a significant prolongation of progression free survival (PFS). However, cogent biomarkers predicting long-term response to EGFR-TKIs are yet lacking. Cancer stem-like cells (CSC) are thought to play a pivotal role in tumor regeneration and appear to be influenced by the EGFR-pathway.

Molecular biomarkers in non-small-cell lung cancer: a retrospective analysis of data from the phase 3 FLEX study.

Background: Findings from the phase 3 FLEX study showed that the addition of cetuximab to cisplatin and vinorelbine significantly improved overall survival, compared with cisplatin and vinorelbine alone, in the first-line treatment of EGFR-expressing, advanced non-small-cell lung cancer (NSCLC). We investigated whether candidate biomarkers were predictive for the efficacy of chemotherapy plus cetuximab in this setting.

Methods: Genomic DNA extracted from formalin-fixed paraffin-embedded (FFPE) tumour tissue of patients enrolled in the FLEX study was screened for KRAS codon 12 and 13 and EGFR kinase domain mutations with PCR-based assays.

The efficacy and safety of BI 2536, a novel Plk-1 inhibitor, in patients with stage IIIB/IV non-small cell lung cancer who had relapsed after, or failed, chemotherapy: results from an open-label, randomized phase II clinical trial.

Objective: To investigate the efficacy, safety, and pharmacokinetics of two dosing schedules of BI 2536, a novel polo-like kinase-1 inhibitor, in patients with relapsed stage IIIB/IV non-small cell lung cancer.

Methods: Ninety-five patients were randomized to intravenous BI 2536 on day 1 (200 mg) or days 1 to 3 (50 or 60 mg) of a 21-day treatment course. BI 2536 doses were escalated beyond course 2 if well tolerated.

A phase II study of irinotecan (CPT-11) and carboplatin in patients with limited disease small cell lung cancer (SCLC).

Purpose: The aim of this phase II trial was to evaluate the efficacy and safety of a combination chemotherapy containing irinotecan (CPT-11) and carboplatin as first-line treatment of patients with small cell lung cancer (SCLC).

Patients And Methods: From December 2002 to May 2004 61 patients with limited disease (IASLC classification) were enrolled who were not suitable for concurrent chemo-radiotherapy. Eighteen of the 61 patients (29.

Dysfunctional inhibitory muscarinic receptors mediate enhanced histamine release in isolated human bronchi.

In human airways mucosal mast cells are under the control of inhibitory muscarinic receptors. The described experiments tested, whether the inhibitory potency of two muscarinic receptor agonists (oxotremorine, acetylcholine) becomes impaired in advanced chronic obstructive pulmonary disease (COPD). Isolated human bronchi obtained from 26 patients with lung cancer were separated into two groups.

Pemetrexed combined with oxaliplatin or carboplatin as first-line treatment in advanced non-small cell lung cancer: a multicenter, randomized, phase II trial.

Purpose: To determine efficacy and toxicity of two pemetrexed-based regimens in chemonaive patients with locally advanced or metastatic non-small cell lung cancer.

Experimental Design: Patients were randomly assigned to receive pemetrexed 500 mg/m(2) plus oxaliplatin 120 mg/m(2) (PemOx) or pemetrexed plus carboplatin AUC6 (PemCb). All drugs were given on day 1 of a 21-day cycle for up to six cycles.

Highly focused T cell responses in latent human pulmonary Mycobacterium tuberculosis infection.

The elucidation of the molecular and immunological mechanisms mediating maintenance of latency in human tuberculosis aids to develop more effective vaccines and to define biologically meaningful markers for immune protection. We analyzed granuloma-associated lymphocytes (GALs) from human lung biopsies of five patients with latent Mycobacterium tuberculosis (MTB) infection. MTB CD4+ and CD8+ T cell response was highly focused in the lung, distinct from PBL, as assessed by TCR-CDR3 spectratyping coupled with a quantitative analysis of TCR VB frequencies.

Longitudinal analysis of Mycobacterium tuberculosis 19-kDa antigen-specific T cells in patients with pulmonary tuberculosis: association with disease activity and cross-reactivity to a peptide from HIVenv gp120.

CD8(+) T cells play a central role in immune protection against infection with Mycobacterium tuberculosis. One of the target epitopes for anti-M. tuberculosis directed CD8(+) T cells is the HLA-A2-restricted 19-kDa lipoprotein peptide VLTDGNPPEV.
