REVIEW
Kaixian Zhang, Qianqian Yuan
Lung cancer continues to be a major health problem and the most common cancer-related mortality worldwide with about 80%-85% patients suffering from nonsmall cell lung cancer (NSCLC). More than 80% of NSCLC cases are often diagnosed as advanced stage and harbor epidermal growth factor receptor (EGFR) activating mutation. Although great success in initial response to EGFR-tyrosine kinase inhibitors (EGFR-TKIs) are found in EGFR-mutant NSCLC patients, acquired resistance usually occurs on the continuous treatment...

We investigate the impact of magnetic resonance (MR) on the staging and radiotherapy planning for patients with nonsmall cell lung cancer (NSCLC).A total of 24 patients with NSCLC underwent MRI, which was fused with radiotherapy planning CT using rigid registration. Gross tumor volume (GTV) was delineated not only according to CT image alone (GTVCT), but also based on both CT and MR image (GTVCT/MR). For each patient, 2 conformal treatment plans were made according to GTVCT and GTVCT/MR, respectively. Dose-volume histograms (DVH) for lesion and normal organs were generated using both GTVCT and GTVCT/MR treatment plans...

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...

Multidrug resistance (MDR) is a main obstacle in cancer chemotherapy. The MDR mechanisms involve P-glycoprotein (P-gp) overexpression, abnormality of apoptosis-related protein, and altered expression of drug-targeting proteins. Therapeutic proteins are emerging as candidates for overcoming cancer MDR because of not only their large molecular size that potentially circumvents the P-gp-mediated drug efflux but also their distinctive bioactivity distinguished from small-molecular drugs. Herein we report trichosanthin, a plant protein toxin, possesses synergistic effect with paclitaxel (PTX) in the PTX-resistance A549/T nonsmall cell lung cancer (NSCLC) cells, by reversing PTX-caused caspase 9 phosphorylation and inducing caspase 3-dependent apoptosis...

RATIONALE: Most of nonsmall cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR) activating mutations eventually acquire resistance to the first EGFR-tyrosine kinase inhibitors (TKIs) therapy after varying periods of treatment. Of note, approximately one-third of those patients develop brain metastases, which deteriorate their quality of life and survival. The effect of systemic chemotherapy on brain metastases after acquisition of EGFR-TKI resistance is limited, and thus far, whole-brain radiation therapy, which may cause the harmful effect on neurocognitive functions, has been the only established therapeutic option for especially symptomatic brain metastases...

This paper presents an improved GrowCut (IGC), a positron emission tomography-based segmentation algorithm, and tests its clinical applicability. Contrary to the traditional method that requires the user to provide the initial seeds, the IGC algorithm starts with a threshold-based estimate of the tumor and a three-dimensional morphologically grown shell around the tumor as the foreground and background seeds, respectively. The repeatability of IGC from the same observer at multiple time points was compared with the traditional GrowCut algorithm...

REVIEW
Fraser R Millar, Sam M Janes, Adam Giangreco
Lung cancer is the most lethal cancer type worldwide, with the majority of patients presenting with advanced stage disease. Targeting early stage disease pathogenesis would allow dramatic improvements in lung cancer patient survival. Recently, cell migration has been shown to be an integral process in early lung cancer ontogeny, with preinvasive lung cancer cells shown to migrate across normal epithelium prior to developing into invasive disease. TP53 mutations are the most abundant mutations in human nonsmall cell lung cancers and have been shown to increase cell migration via regulation of Rho-GTPase protein activity...
