Lung cancer screening

Joanna Pancewicz-Wojtkiewicz
Lung cancer is the most common reason of cancer deaths and about 85% of these are non-small-cell lung cancer. Currently, lung cancer therapy is mainly based on the tumor node metastasis (TNM) disease staging and tumor histological classification. Despite therapeutic innovations, the prognosis for lung cancer patients has not significantly changed in the last years. Therefore, a proper understanding of cell signaling pathways involved in cancer pathogenesis seems to be essential for improvement in cancer therapy field...

Inflammation is proposed to increase risk of developing endometrial cancer, but few prospective epidemiologic studies have investigated the relationship between circulating inflammation markers and endometrial cancer risk. In a nested case-control study within the PLCO Screening Trial we measured serum levels of 64 inflammation-related biomarkers in 284 incident endometrial cancer cases and 284 matched controls. Using multivariable logistic regression inflammation markers were evaluated individually and combined into a cross-validated inflammation score...

Lung cancer has the highest mortality rate among cancer patients in the world, in particular because most patients are only diagnosed at an advanced and non-curable stage. Computed tomography (CT) screening on high-risk individuals has shown that early detection could reduce the mortality rate. However, the still high false-positive rate of CT screening may harm healthy individuals because of unnecessary follow-up scans and invasive follow-up procedures. Alternatively, false-negative and indeterminate results may harm patients due to the delayed diagnosis and treatment of lung cancer...

The purpose of the study was to explore the application of artificial neural network model in the auxiliary diagnosis of lung cancer and compare the effects of back-propagation (BP) neural network with Fisher discrimination model for lung cancer screening by the combined detections of four biomarkers of p16, RASSF1A and FHIT gene promoter methylation levels and the relative telomere length. Real-time quantitative methylation-specific PCR was used to detect the levels of three-gene promoter methylation, and real-time PCR method was applied to determine the relative telomere length...

Clinical PI3K inhibition has been somewhat disappointing, due to both inadequate patient stratification and compensatory cell signalling through bypass mechanisms. As such, investigation of PI3K-MEK co-targeted inhibition has been recommended. With high mortality rates and a clear need for new therapeutic intervention strategies, non-small cell lung cancer (NSCLC) is an important setting to investigate the effectiveness of this approach.Here, 174 NSCLC tumours were screened for 150 mutations by Fluidigm technology, with 15 patients being profiled for phosphoprotein expression...

A 69 year-old homeless African American male with prostate cancer diagnosed 2 years prior presents a large mass in the right thigh. Evaluation of the patient revealed a PSA of 9,362 ng/ml. IR biopsy of the leg mass was performed and final pathology indicated metastatic adenocarcinoma of the prostate. While metastatic prostate cancer presents most commonly in bone, lymph nodes, lungs and liver, metastatic disease presenting as a soft tissue mass is extremely rare.(1,2,3) Advent of screening with PSA has led to earlier diagnosis of lower grade disease, yet underserved populations continue to present with aggressive and morbid disease...

Lung cancer is the leading cause of cancer mortality currently. Early diagnosis is crucial to the good prognosis of lung cancer. Evidence has shown that low-dose computed tomography (CT) screening can make the decline in the mortality of lung cancer. However, there are still many problems in the screening, such as, high false-positive rates, overdiagnosis and radiation exposure. As another non-invasive tumor screening method, blood-based tumor markers showed a high sensitivity and specificity in early diagnosis of lung cancer in recent years...

BACKGROUND: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are remarkably effective for treating EGFR-mutant non-small cell lung cancer (NSCLC). However, the individual role of EGFR-TKIs in patients with brain metastasis (BM) arising from EGFR-mutant NSCLC remains unclear. METHODS: Patients with BM secondary to NSCLC and harboring EGFR-activating mutations were retrospectively screened. Patients who received gefitinib or erlotinib to control both extracranial lesions (ECLs) and intracranial lesions (ICLs) were eligible...

BACKGROUND: Evidence suggests that obesity in adulthood is associated with increased risk of "clinically significant" prostate cancer. However, studies of body mass index (BMI) across the adult life course and prostate cancer risks remain limited. METHODS: In a prospective cohort of 69 873 men in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial, we examined associations of prediagnostic BMI across the adult life course with risk of incident prostate cancer and fatal prostate cancer (prostate cancer-specific mortality)...

U2AF homology motifs (UHMs) are atypical RNA Recognition Motif (RRM) domains that mediate critical protein-protein interactions during the regulation of alternative pre-mRNA splicing and other processes. The recognition of UHM domains by UHM Ligand Motif (ULM) peptide sequences plays important roles during early steps of spliceosome assembly. Splicing factor 45 kDa (SPF45) is an alternative splicing factor implicated in breast and lung cancer and splicing regulation of apoptosis-linked pre-mRNAs by SPF45 was shown to depend on interactions of its UHM domain with ULM motifs in constitutive splicing factors...

BACKGROUND: Osimertinib (AZD9291) is an oral, potent, irreversible EGFR tyrosine-kinase inhibitor selective for EGFR tyrosine-kinase inhibitor sensitising mutations, and the EGFR Thr790Met resistance mutation. We assessed the efficacy and safety of osimertinib in patients with EGFR Thr790Met-positive non-small-cell lung cancer (NSCLC), who had progressed after previous therapy with an approved EGFR tyrosine-kinase inhibitor. METHODS: In this phase 2, open-label, single-arm study (AURA2), patients aged at least 18 years with centrally confirmed EGFR Thr790Met-positive mutations, locally advanced or metastatic (stage IIIB/IV) NSCLC who progressed on previous EGFR tyrosine-kinase inhibitor therapy received osimertinib 80 mg orally once daily; treatment could continue beyond progression if the investigator observed a clinical benefit...

BACKGROUND: The density of particulate matter (PM) in mega-cities in China such as Beijing and Shanghai has exceeded basic standards for health in recent years. Human exposure to PMs has been identified as traceable and controllable factor among all complicated risk factors for lung cancer. While the improvement of air quality needs tremendous efforts and time, certain revision of PM's density might happen associated with the adjustment of built environment. It is also proved that urban built environment is directly relevant to respiratory disease...

Targeted therapy in lung cancer changes the prognostic and treatment of patients. MET is an oncogene including exon 14 mutations and gene amplification associated with worse prognosis. We here report the case of a 47-year-old former smoker, woman, with a stage IV lung adenocarcinoma with multiple chemotherapy failure. A MET amplification was identified and the patient consequently received crizotinib. A major response was observed after eight weeks of treatment. MET amplification screening appears to be interesting with some oncogenic-addicted tumor response rate...

The NADPH oxidase proteins catalyse the formation of superoxide anion which act as signalling molecules in physiological and pathological processes. Nox1-dependent NADPH oxidase is expressed in heart, lung, colon, blood vessels and brain. Different strategies involving Nox1 inhibition based on diphenylene iodonium derivatives are currently tested for colorectal cancer therapy. Here, after peptides screening on Nox1-dependent NADPH oxidase assay in HT-29 cells, we identify a peptide (referred to as NF02), cell-active, that potently block Nox1-dependent reactive oxygen species generation...
