Active clinical trials for "Carcinoma, Non-Small-Cell Lung"

In this study, investigators plan to test whether Immune Checkpoint Inhibitor (ICI) treatment leads to an accelerated progression of atherosclerosis in patients with lung cancer. Atherosclerosis is an immune-mediated inflammatory disease and these same checkpoints being targeted for cancer are critical negative regulators of atherosclerosis in animal and cellular models. Aortic plaque progression will be compared between cases (on ICI) and controls from pre-ICI to post-ICI among patients with non-small cell lung cancer. Groups will be matched for age, cancer type and stage and cardiovascular risk factors. Traditional markers of cardiovascular (CVD) risk and cancer-specific factors (ICI mono- and combination therapy, number of cycles, occurrence of immune-related adverse events, chest radiation, steroid use) will be associated with the change in aortic plaque volume.

The effect of body composition on the survival rate is one of the research topics of interest in cancer patients and gaining attention in the last years. Body mass index is often used a proxy measure of total adiposity and previous studies examining the relationship between BMI and cancer outcomes have been showed distinct results . Obese patients with malignancies such as colorectal, breast, and pancreatic cancers, have been shown to have a worse prognosis than normal-weight patients . Nevertheless, obese patients with non small cell lung cancer(NSCLC) have been observed to have a better clinical outcome than normal/low-weight cancer patients . In this study, we examined the effects of subcutaneous adipose tissue, visceral adipose tissue and skeletal muscle volumes on survival in metastatic NSCLC patients under different treatment regimens. Since there is no standard method for adipose tissue measurement, we evaluated the abdominal cavity with multi-slice and single-slice computed tomography measurements.

About 20-30% of patients with stage III non-small cell lung cancer (NSCLC) are unresectable and definitive concurrent radiochemotherapy is the standard care. Intensity-modulated radiation therapy (IMRT) is a new radiotherapy technology, including gross tumor volume (GTV), clinical target volume (CTV), internal target volume (ITV), and planning target volume (PTV) as delineated target volumes. The treatment failure of local advanced NSCLC is mainly caused by local recurrence accounted for 50% and distant metastasis accounted for 50%. Local recurrence occurs both within the radiation field and outside the radiation field. Elective nodal irradiation (ENI) was designed before, however the adverse events (AEs) was not satisfactory. Afterwards, involved field radiotherapy (IFRT) showed that a reduced irradiation field did not increase local recurrence, and lowered the AEs Thus, IFRT has been broadly used in clinical work instead of ENI. IFRT still has disadvantages, including the risk of radiation respiratory events and radiation esophagitis, can the irradiation area be further reduced to reduce adverse reactions without affecting the efficacy? Positron emission tomography -computed tomography (PET-CT) can accurately assess primary tumor and metastatic lymph nodes in NSCLC patients better than CT . A meta-analysis of 39 clinical studies showed that the median sensitivity and specificity of PET-CT for the detection of lymph node involvement were 85% and 90%, respectively, while those of CT alone were only 61% and 79%, respectively. The radiotherapy application of PET-CT in image acquisition can ensure the delineation of both primary tumor and mediastinal lymph node metastasis. Under this condition, can the radiation field be further reduced to lower the dose to normal tissue and radiotherapy-associated AEs? A dosimetry study showed that when a dose of 60 Gy was given to the primary tumor and positive mediastinal lymph nodes, even if the CTV was omitted, a dose of 50 Gy was sufficient to cover the subclinical area.

The main aim is to evaluate sociodemographic and clinical characteristics of advanced Non-Small Cell Lung Cancer (NSCLC) in adults participants with epidermal growth factor receptor (EGFR) exon 20 insertions mutations during the 5 years before data extraction date (from 1-Jan-2017 to 1-Jan-2022). Participants will not receive any drug. This study will only collect the data from the medical records via chart review.

To assess the effectiveness and safety of osimertinib treatment in a real world setting.

It is a study that hypothesize that MR/PET can have better information than current CT image study, about the medical or surgical treatment outcome of lung cancer

This observational study was planned, with the primary objective to observe patient survival following first-line treatment of patients of Stage IIIB/IV Non-small Cell Lung Cancer (NSCLC) with different platinum-based doublets under routine disease management conditions. Further secondary objectives of this study are to provide insights to what extent histologic subtyping and the use of additional prognostic or predictive biomarkers are currently considered for differential therapeutic decisions under routine conditions. All of these data are critical to evaluate the factors for differential therapeutic decisions and their effect on patient outcomes in a real life setting, and they can only be obtained through observational research.

This randomized clinical trial studies enhanced quitline intervention in smoking cessation for patients with non-metastatic lung cancer. Stop-smoking plans suggested by doctors may help patients with early-stage cancer quit smoking

The accurate staging is an essential part for the treatment and prognosis of non-small-cell lung cancer (NSCLC). Whole body MR imaging proved to be effective in staging of NSCLC as much as PET/CT. And there were organs of strength for each modality in the detection of metastasis. Therefore, integrated approach using whole body MR and PET would be more beneficial for the accurate staging of lung cancer with improved diagnostic efficacies and reduced radiation exposure. The aim of this project is to evaluate the diagnostic efficacy of side-by-side reading of whole-body magnetic resonance imaging/ positron emission tomography (MRI/PET) and to compare with that of whole-body magnetic resonance imaging (WB MRI) alone and that of integrated PET/CT in determining the stage of NSCLC. Patients with pathologically-proven NSCLC will be prospectively enrolled, if they are considered as surgical candidates for the treatment of lung cancer through conventional methods of staging, i.e. history taking, physical examination, blood tests, bronchoscopy, and enhanced chest CT scans. PET/CT will be routinely performed for the staging of lung cancer in our institution. For the purpose of this study, whole body MRI will be performed for these patients within 3 days from the date of acquisition of PET/CT. The results of TNM staging from each modality will be collected prospectively and their efficacies can be calculated based on the reference standards. Reference standards of T and N staging will be surgically confirmed. And M staging can be confirmed by biopsy, other imaging modalities, or follow-up more than 6 months. Diagnostic efficacies of coregistered MRI/PET can be evaluated with the comparison from the consecutive two-arm enrollment with random assignment of control group and study group as follows: control group: routine staging work-up with chest CT, PET/CT, and brain MRI study group: routine staging work-up plus whole body MRI for Coregistered MRI/PET

Background: - Research has shown that the Epidermal Growth Factor Receptor (EGFR) gene is an important target for personalized lung cancer treatment. Individuals who have mutations in the EGFR gene have better responses when treated with certain personalized or targeted therapies compared with conventional chemotherapy. These mutations are more frequent in females with lung cancer who have never smoked, and different ethnic groups have different levels of frequency of the mutations. Researchers are interested in collecting more information on EGFR genetic mutations in Hispanics/Latinos with lung cancer, comparing the frequency of these mutations in males and females and smokers and nonsmokers. This study may lead to better, more personalized care approaches for all individuals with lung cancer. Objectives: - To study the frequency of Epidermal Growth Factor Receptor mutations in Hispanic/Latino individuals who have been diagnosed with non-small cell lung cancer. Eligibility: - Hispanic or Latino individuals who have been diagnosed with non-small cell lung cancer and who have lung tissue from a previous biopsy or surgery available for research purposes. Design: Participants will provide consent for researchers to examine lung tissue collected from a previous biopsy or surgery. Treatment will not be provided as part of this protocol.
