BACKGROUND: Epidermal growth factor receptor (EGFR) mutation testing in tumor tissue is now a common practice in selecting non-small cell lung cancer (NSCLC) patients for EGFR tyrosine kinase inhibitor (TKI) treatment. However, tumor tissues are often absent or insufficient for the testing. Blood is a potential substitute providing a noninvasive, easily accessible and repeatedly measureable source of genotypic information. However which is the best blood EGFR mutation testing method remains unclear...

Personalized, individualized, targeted therapy has successfully found entrance in the palliative treatment of lung cancer as they enable a personalized and individualized strategy going ahead with biomarker testing. Due to the crescending amount of predictive molecular and immunhistochemical analyses at different time points during therapy the need for more and actual tumor tissue increases; however these samples cannot always be obtained without major discomfort for the patients. Therefore, analyses from blood, the so called "liquid biopsy", is an alternative or additional method...

Lung cancer is the leading cause of cancer deaths worldwide, with smoking as the main risk factor. The use of low-dose computed tomography (LDCT) as a screening method has shown a 20% lung cancer specific mortality benefit; however, widespread implementation is estimated to add $1.3-$2.0 billion in annual national health care expenditures. Blood-based microRNAs (miRNAs), have been investigated in detail and found to be potentially useful biomarkers indicating the presence of lung cancer, especially when used as a companion test to LDCT...

BACKGROUND: When tumour tissue is unavailable, cell-free DNA (cfDNA)can serve as a surrogate for genetic analyses. Because mutated alleles in cfDNA are usually below 1%, next-generation sequencing (NGS)must be narrowed to target only clinically relevant genes. In this proof-of-concept study, we developed a panel to use in ultra-deep sequencing to identify such mutations in cfDNA. METHODS: Our panel ('SiRe') covers 568 mutations in six genes (EGFR, KRAS, NRAS, BRAF, cKIT and PDGFRα)involved in non-small-cell lung cancer (NSCLC), gastrointestinal stromal tumour, colorectal carcinoma and melanoma...

Long interspersed nuclear element 1 (LINE-1 or L1) belongs to the non-long terminal repeat (non-LTR) retrotransposon family, which has been implicated in carcinogenesis and disease progression. Circulating tumor cells (CTCs) are also known to be involved in cancer progression. The present study aimed to compare the L1 expression between circulating tumor cells and non-cancerous samples. Blood samples were collected from 10 healthy individuals and 22 patients with different types of cancer. The whole blood cells were isolated using enrichment protocols and the DNA and RNA were extracted...

BACKGROUND: Docetaxel is a cytostatic agent approved for treatment of non-small cell lung cancer as well as other cancers. Although docetaxel is an effective cytostatic agent, its effectiveness in clinical practice is associated with a variety of acute and long term side-effects. To overcome systemic side effects, a slow release formulation based on calcium sulfate with docetaxel for intra-tumoral administration was developed. METHODS: Two formulations with the calcium sulfate NanoZolid technology were generated with a twofold difference in docetaxel drug load...

BACKGROUND: Routine clinical application of circulating tumour cells (CTCs) for blood based diagnostics is yet to be established. Despite growing evidence of their clinical utility for diagnosis, prognosis and treatment monitoring, the efficacy of a robust platform and universally accepted diagnostic criteria remain uncertain. We evaluate the diagnostic performance of a microfluidic CTC isolation platform using cytomorphologic criteria in patients undergoing lung cancer surgery. METHODS: Blood was processed from 51 patients undergoing surgery for known or suspected lung cancer using the ClearBridge ClearCell FX system(TM) (ClearBridge Biomedics, Singapore)...

BACKGROUND: Pneumonectomy is a proven treatment for lung diseases. We sought to present a comparison between video-assisted thoracic surgery pneumonectomy (VATS-P) and conventional thoracotomy pneumonectomy (CP) on perioperative outcomes and short-term measures of convalescence. METHODS: A retrospective cohort study was performed to assess perioperative outcomes among patients underwent VATS-P and CP. A total of 32 patients undergoing VATS-P were matched 2:1 about comorbidity, surgical indication, tumour size and lesion location to a previous cohort of 64 patients who underwent CP...

INTRODUCTION: Most pulmonary nodules found on imaging studies are indeterminate, but because of the concern for lung cancer, all patients require further evaluation with resultant radiation risk, significant cost and delays in diagnosis. We hypothesized that a diagnostic blood test based on detection of autoantibodies against cancer antigens would be able to distinguish a benign nodule from lung cancer. METHODS: We identified a panel of 25 serum autoantibodies associated with NSCLC and constructed a protein microarray containing the autoantigens...

BACKGROUND: One-lung ventilation during thoracic surgery frequently disturbs normal systemic oxygenation. However, the effect of anesthetics on arterial oxygenation during one-lung ventilation has not been well established in human study. In this clinical trial, we investigated whether a difference between desflurane-remifentanil and propofol-remifentanil anesthesia can be observed with regard to oxygenation during one-lung ventilation for thoracoscopic surgery. METHODS: Adult patients with lung cancer, scheduled for video-assisted thoracoscopic lobectomy without preoperative oxygen support, were screened and randomized to receive desflurane or propofol, with remifentanil continuous infusion in both groups...

Liquid biopsy is a blood test that detects evidence of cancer cells or tumor DNA in the circulation. Despite complicated collection methods and the requirement for technique-dependent platforms, it has generated substantial interest due, in part, to its potential to detect driver oncogenes such as epidermal growth factor receptor (EGFR) mutants in lung cancer. This technology is advancing rapidly and is being incorporated into numerous EGFR tyrosine kinase inhibitor (EGFR-TKI) development programs. It appears ready for integration into clinical care...

Inhaled titanium dioxide (TiO2) nanoparticles (NPs) can have negative health effects, and have been shown to cause respiratory tract cancer in rats. Inflammation has been linked to oxidative stress, and both have been described as possible mechanisms for genotoxicity of NPs, but rarely examined side-by-side in animal studies. In the present study, a wide range of complementary endpoints have been performed to study TiO2 P25 NP-induced genotoxicity in lung overload and non-overload conditions. Additionally, lung burden, inflammation, cytotoxicity and oxidative stress have also been evaluated in order to link genotoxicity with these responses...
