Active clinical trials for "Lung Neoplasms"

Does the routine clinical practice of follow up after primary treatment in lung cancer patients has any utility.

The purpose of this study is to characterize the demographic and clinical aspects, and describe the frequency and type of KRAS mutation in a Brazilian population sample with advanced non-small cell lung cancer (NSCLC).

There is currently a lack of published HER3 expression prevalence data among non-small cell lung cancer (NSCLC) patients. The estimation of HER3 expression prevalence in this population using archival tissue samples and the assessment of associated patient characteristics in real world (RW) data will ultimately inform clinical strategy and increase awareness among health care providers (HCPs) and the greater medical community to improve patient care.

In developed countries cancer has become the second leading cause of death after cardiovascular disease. The lung is a particularly exposed organ since broncho-pulmonary cancers rank second in terms of incidence, and the first rank in terms of mortality of all cancers listed in like reported in United States. Lung resection surgery is currently the recommended curative treatment for the early stages of non-small cell lung cancer (NSCLC). Despite this preferred indication, some patients can not be eligible for surgery because of their cardiovascular or respiratory comorbidities or their impaired functional capacity. Thus, the evaluation of aerobic capacity through cardiopulmonary exercise testing (CPET) of patients estimated at risk of postoperative complication is now recommended to estimate the level of predictive risk associated. The American Thoracic Society and the European Respiratory Socitety agree on thresholds of <10 and> 20 ml/kg/min of maximum oxygen uptake (VO2peak) respectively determining a high or low postoperative risk, between these two thresholds risk is considered moderate. Aerobic capacity is traditionally expressed in terms of maximum oxygen uptake (VO2max or VO2peak) evaluated during an incremental CPET. In patients with significant respiratory impairment, these tests are often limited by ventilation and sub-maximally on the metabolic or cardiac parameters. However, the analysis of the VO2 kinetic during a constant-intensity test of moderate intensity is also a relevant way of measuring aerobic conditioning. Indeed, the time constant (τ) of phase II of VO2 kinetics (VO2τ) is a marker that closely reflects the adjustment of oxidative metabolism in skeletal muscle. Analysis of the kinetic parameters of the cardio-respiratory response to exercise has been shown to be reproducible and training-sensitive in patients with chronic obstructive pulmonary disease (COPD). The value of VO2τ was also reported to be strongly correlated with markers of severity and prognosis in COPD patients. Previous work has shown that exercise training can improve the speed of the VO2 kinetic response in COPD patients as well as in healthy subjects. To date, no study to our knowledge has evaluated the kinetics of the cardiorespiratory response during moderate intensity constant-load test in patients with NSCLC. In this context, this work aims to evaluate the applicability of this measure as well as its evolution during a preoperative exercise training program in patients with NSCLC.

Whether using a guide sheath can increase the diagnostic yield rate after the lesion is located by radial endobronchial ultrasound

Lung cancer is one of main cause of cancer death in worldwide, characterized of low 5-year survival rate of less than 20%. Pulmonary nodule is considered as the typical imaging manifestation in early stage of lung cancer. The National Lung Screen Trial has demonstrated that the mortality rates could decline greatly, by the utility of low-dose helical computed tomography for screen of pulmonary nodules. Thus, automatic detection, diagnosis and management of pulmonary nodules, play the vital roles in computer-aided lung cancer screening and early intervention.

Conduct a prospective study to compare gene detection by ctDNA with tumor tissue DNA via targeted DNA sequencing in surgical NSCLC patients.

The study aims to explore the prevalence of EGFR mutations assessed with ctDNA samples in advanced NSCLC, who had received ≤ 1 prior systemic chemotherapy regimens.

This study will be carried out on 40 subjects at Chest department Tanta university hospital The subjects will be classified into three groups: Group I: will include ten non smoker volunteers (control group I). GroupII: will include ten smoker volunteers (control groupII). Group III: will include twenty NSCLC patients confirmed by pathological examination of bronchoalveolar examination (BAL), brush and/or biopsy.

The COPDGene® / Lung Cancer Database Study is a nested case-control study. This study is an ancillary study to COPDGene® Phase 1 and Phase 2. Lung cancer cases, which have been reported by COPDGene® subjects since the time of COPDGene® study enrollment, will be retrospectively verified with additional medical data collection pertaining to lung cancer. Additional 'control' subjects will also be identified and verified as a 'no lung cancer controls'. Data previously collected through the COPDGene® Study, including QCT results and clinical results (medication use, rate of acute exacerbations of COPD, etc) will be used as variables for analysis.
