Development of Circulating Tumour Cell Molecular Diagnostics Using a Novel Microfluidic Device
Patients With Non-small Cell Lung CancerTo compare EGFR mutations between primary non-small cell lung cancer (NSCLC) tumours and corresponding CTCs isolated by a label-free microfluidic device-based system To characterize the association between clinical response in NSCLC patients treated with gefitinib and serial changes in CTC EGFR mutations detected by a label-free microfluidic device-based system The investigators recently developed a label-free, microfluidic device for capturing circulating tumour cells (CTCs) and acquired a Fluidigm Biomark digital PCR instrument for reliable low-level DNA quantification. The overall aim of this study is to test the feasibility of using these state-of-the-art devices to reliably detect clinically relevant EGFR mutations in CTCs.
Gene-expression Profiles in CNS-metastatic Non-small Cell Lung Cancer
Brain DiseaseMetastasis1 moreNon small-cell lung cancer (NSCLC) accounts 85% of all lung cancer.The development of brain metastasis diminished life expectancy to less than one year with a median survival of less than three months. In NSCLC cancer, approximately 50% of patients with locally advanced disease develop brain metastasis at some time during the natural of disease. The central nervous system constitutes the first site of recurrence in 15 to 40% of these patients. Microarrays evaluate the diagnosis, treatment and prognosis of lung cancer.There are no studies that specifically evaluate the relationship between a genetic profile of NSCLC and metastasis to the CNS, with the purpose of distinguishing a subgroup of patients that will benefit of prophylactic treatment.What is the association between a genetic profile on NSCLC and the development of CNS metastasis.Obtaining a genetic profile from the primary NSCLC tumor cells, by using microarrays, we can predict the development of CNS metastasis arise a subgroup of patients that could benefit from prophylactic cranial radiation with which their quality of life and prognosis most probably will increase.Objective:Determine the association between a genetic profile from the primary tumor cells and the development of central nervous system metastasis in patients with non small-cell lung cancer.A genetic profile from the primary tumor cells are associated with the development of central nervous system metastasis in patients with NSCLC. A clinical, prospective, analytic, open, non randomized, prognostic and observational cohort with 66 patients with NSCLC who authorize a biopsy study from February, 2008 to December, 2012, INMEGEN institute will be in charge of performing the microarrays and the computer analysis in order to obtain the different genetic profiles that will be differentially expressed related with CNS metastasis risk profiles. Patients will be followed-up by means of the external consult of lung neoplasms. The statistical analysis will be performed using tests like Student's t or Mann-Whitney's U test. A multivariate analysis of logistic regression will be performed. Global survival time will be analyzed using Kaplan-Meier's technique and the comparison between groups will be performed with log-rank test. The adjustment for potential confusors will be performed using multivariate regression analysis. For result representation, we will use tables and graphs and pertinent measures will be taken to disclose the study.
Preconditioning Chemotherapy Combination With Cytokine Induced Killer Cell (CIK) Immunotherapy
Non Small Cell Lung CancerThis clinical Trial is proposed to explore whether preconditioning chemotherapy of Paclitaxel+cisplatin(TP)regimen combined with autologous adoptive CIK cell immunotherapy could benefit NSCLC patients with a better clinical outcome.

A Multi-center Prospective Observational Biomarker Study on EGFRm+ Non-small Cell Lung Cancer Patients...
Non-small Cell Lung CancerLeptomeningeal MetastasisLeptomeningeal metastasis (LM) is one of the disastrous events when managing advanced Non-small cell lung cancer (NSCLC) due to a grave prognosis. Although intrathecal (IT) chemotherapy and brain and/or spinal axis irradiation show some effects for LM in advanced NSCLC, the prognosis is still poor with median survival less than 12-14 weeks. Epidermal growth factor (EGFR) tyrosine kinase inhibitors (TKIs) showed to be effective for LM in selected NSCLC patients in some retrospective research. Our single-center prospective research indicated that the incidence of EGFR sensitive mutations (EGFRm+) in NSCLC-LM patients was high and EGFR-TKIs showed a survival benefit for LM in EGFRm+ NSCLC patients. A multi-center prospective observational biomarker study will be started in 11 lung cancer center based on our single-center prospective research result. The aims of the study are to find predictive biomarkers for LM in advanced NSCLC, to establish EGFR-TKIs based comprehensive treatment for appropriate EGFRm+ LM cases, and to establish effective clinical assessment criteria for NSCLC-LM EGFR-TKIs treatment.
PDX Models From EGFR Mutant Tumors
Non Small Cell Lung CancerA biospecimen collection study from individuals with EGFR mutant cancers resistant to EGFR TKIs or those harboring an Exon 20 insertion mutation.
Analysis of Biopsy Specimens to Study Responses to PD-1 or PD-L1 Therapies
Non Small Cell Lung CancerThe purpose of this study is to attempt to obtain an on-treatment biopsy in participants with non-small cell lung cancer who are receiving standard treatment with a drug that targets the PD-1 or PD-L1 protein.
Epidermal Growth Factor Receptor (EGFR) T790M Mutation Testing Practices in Hong Kong
Non-small Cell Lung CancerTo describe the T790M mutation status of patients with locally advanced/metastatic NSCLC who progressed on previous EGFR TKI treatment in a real-world setting.
A Study of Cesium-131 Brachytherapy Following Sub-Lobar Resection for Early Stage Non Small Cell...
NSCLCNon Small Cell Lung CancerFor patients diagnosed with early (Stage I) non-small cell lung cancer, a lobe of lung is usually removed at surgery to treat the cancer. For some patients, the removal of a lobe of lung may leave too little lung behind for easy breathing. For some of these patients, it may be possible to perform a smaller-scale surgery ("sub-lobar resection") and place a radioactive implant behind to prevent the cancer from growing back. This study will see how these patients do in terms of controlling their disease treated with a radioactive implant called Cesium-131.
