Active clinical trials for "Lung Neoplasms"

A new software product takes two chest radiographs, aligns them, and then subtracts one image from the other. The resulting image represents an image showing any differences between them. The study is to determine whether radiologists using this new software perform better with it than when they do not use it.

This is a retrospective, descriptive analysis of (1) 30 day postoperative results of surgery for lung cancer, (2) 30 day outcome predictors - compared to an earlier similar study in the same hospital (St Olav University Hospital, Trondheim, Norway).

Narrow band imaging (NBI) videobronchoscopy is an optical technique in which filtered light enhances superficial neoplasm based on their neoangiogenic pattern. The objectives of this study investigate its better diagnostic yield in the assessment of lung cancer than conventional flexible bronchoscopy.

The usual response to chemotherapy is decided through the image change by computed tomography (CT), which is taken at least 6-9 weeks. In order to predict the response to chemotherapy earlier, patients received FDG-PET scan at the first cycle of chemotherapy. Chemotherapy was guided by the metabolic response by FDG-PET scan.

L-[3-18F]-α-methyltyrosine (18F-FMT) is an amino-acid tracer for positron emission tomography (PET). The investigators evaluated the value of 18F-FMT PET for the assessment of therapy response in patients with lung cancer as compared with that of 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) PET. The patients with lung cancer underwent PET studies with 18F-FDG and 18F-FMT before and after radio-/chemotherapy. The investigators used the ratio of the SUVmax of the mediastinal (N2) lymph node to the SUVmax of the primary tumor (N/P ratio ). All patients were divided into two groups of N/P ratio<1 and N/P ratio≥1, and the survival time was estimated by Kaplan-Meier method.

Purpose: L-[3-18F]-α-methyltyrosine (18F-FMT) is an amino-acid tracer for PET. We have conducted a clinicopathologic study to elucidate the correlation of angiogenesis with 18F-FMT and 18F-FDG uptake in the patients with non-small cell lung cancer (NSCLC). Method: Thirty-seven NSCLC patients were enrolled in this study, and a pair of PET study with 18F-FMT and 18F-FDG was performed. Uptake of PET tracers was evaluated with standardized uptake value. VEGF, CD31, CD34, LAT1 and Ki-67 labeling index of the resected tumors were analyzed by immunohistochemical staining, and correlated with the clinicopathologic variables and the uptake of PET tracers.

Primary Objectives: To longitudinally assess the natural history of symptoms (prevalence, severity, patterns of symptoms, and the relationship of physical and psychological distress) among post-thoracic surgery for non-small cell lung cancer patients with early stage (stage I-IIIA) disease. To determine crisis events (when symptoms are most severe), their relationship with cancer therapy, surgical techniques and disease, and their relationship with function and quality of life; and to determine current practice patterns of symptom control throughout the six months of the post-surgical phase. To determine the utility of a weekly, telephone-administered interactive voice response symptom assessment (IVR-MDASI) for identifying emergent clinically significant symptoms in this population. To develop symptom severity critical values and critical treatment algorithms for post-operative symptom control for NSCLC patients.

Questionnaire study to observe the incidence and pattern or nausea and vomiting in patients receiving combined chemotherapy and radiation. 83% of patients experience radiation therapy-induced vomiting; significant nausea and vomiting could develop with concurrent chemotherapy despite standard anti-nauseous medication prophylaxis.

The purpose of this study is in non small-cell lung cancer stage IV et IIIB (T4 with pleural effusion) in elderly dependent patients with evaluation of the sequence Gemcitabine first line followed by Erlotinib when progression versus Erlotinib first line followed by Gemcitabine when progression

This phase II trial is studying how well a frailty index and geriatric assessment works in predicting toxicity to front-line chemotherapy in treating patients with stage IV non-small cell lung cancer. A frailty index and geriatric assessment prior to treatment may help identify a better treatment regimen
