Cancer Panel From Blood of Lung Cancer Patients
Non Small Cell Lung Cancer MetastaticNon Small Cell Lung Cancer RecurrentMolecular profiling of lung cancers using circulating tumor DNA (ctDNA) in the blood of patients is rapidly becoming established as a useful source of information to aid clinical decision-making. This study is aimed to to compare concordance rate between tissue based cancer panel analysis and blood based cancer panel analysis in lung cancer patients (both by NGS technique).
A Retrospective EGFR Mutation Status Study in Chinese NSCLC Patients Using Paired Plasma and Tissue...
CarcinomaNon-Small-Cell LungEGFR mutations plays an essential role in EGFR-TKIs treatment. However, for some patients, tissue samples are not available. The purpose of this study is to determine whether blood sample is feasible for EGFR mutation detection.For late stage NSCLC, we hypothesis plasma sample is an alternative for detecting EGFR mutations.
Characterization of Peripheral Muscle Function in Patients With Non-small-cell Lung Cancer
Non-Small-cell Lung CancerRationale: With 1.6 million new cases diagnosed each year and 1.3 million deaths, lung cancer is the leading cancer-related death worldwide and it represents a pressing health issue. Patients with lung cancer are more likely to experience cachexia, a severe debilitating disorder causing fatigue, weight loss, muscle wasting and associated with reduced physical function, increased chemotherapy toxicity and reduced survival. This syndrome occurring in about 80% of advanced cancer patients is the direct cause of death in about 20% of cases. However, despite the importance of cachexia in lung cancer, its mechanisms ans its relation with muscle function and effort tolerance are still unknown. Aim: To explore muscle function, signaling pathways and its relationship to impaired functional capacity of patients with non-small-cell lung cancer(NSCLC); depending of whether they have cachexic state at diagnosis. Methods: This study will be conducted at the Institut universitaire de cardiologie et de pneumologie de Québec. 56 patients newly diagnosed of NSCLC will be recruited and separated whether or not they have a cachexic state. The evaluation will need two visits separated by 5 days. During the evaluation the following tests will be done: Anthropometric measures Level of daily physical activity Pulmonary function test Maximal incremental cardiopulmonary exercise test on ergocycle Endurance test on ergocycle Muscle function tests Magnetic stimulation Quadriceps biopsy
