Lung Cancer - Molecular Markers

September 27, 2016
The authors assessed the relationship between second hand smoke exposure in non-smokers and mortality related to lung cancer using serum cotinine levels.  Cotinine levels were associated with survival, death from lung cancer, and death from all cancers after adjustment.  Such levels identify second hand smoke effects.

This is an outstanding and provocative editorial comment concerning treatment costs of lung cancer based on an article published in the last issue of the European Respiratory Journal.  It reveals discrepancies in access to new therapies based on therapeutic targets due to molecular testing and treatment costs.

This comprehensive review outlines changes in the WHO classification of lung tumors, chagnes that will affect our clinical practice in the near future.

Pts with suspected lung cancer underwent sampling of normal-appearingbronchial epithelial cells in the main bronchi, unrelated to the suspected tumor.  Gene expression was analyzed and classified.  Classification for cancer was about 75% accurate.

Targeting specific genetic changes in cancer cells offers patients personalized therapy for their tumors.  The number of identified abnormalities is rapidly increasing, and determining whether they represent driver mutations or background noise is increasingly difficult.  The IBM Watson supercomputer will be used by 10 US cancer centers to identify a

Concerns remain about the definition of a high risk population who can benefit from low-dose computed tomography screening programs.

Samples from tissue microarrays of 552 NSCLC patients were analyzed to measure the levels of 3 different tumor-infiltrating lymphocytes (TILs): CD3, CD8, and CD20. An elevated level of CD3 or CD8 was associated with longer survival.

This study was conducted in 94 lung adenocarcinoma patients matching pairs from current, former and never smokers' lung adenocarcinoma and non-malignant lung parenchymal tissue.   Investigators discovered different smoking-specific microRNA differences.

Differentiating a primary lung cancer from an intrapulmonary metastasis can be challenging.  The authors developed a lineage test using whole genome amplification and next-generation sequencing to identify breakpoints in known primary tumors and known metastases.  Independent primary tumors did not share any genomic rearrangements, whereas primary tu

In this promising investigation, authors have found changes associated with airway cancerization in large airways in lung cancer patients, while these changes are absent in cancer-free smokers. And in addition, with shorter distance from tumors, airway cancerization expression increases statistically.
