Active clinical trials for "Lung Neoplasms"

Calculating which cardiac substructure accepting with the highest radiation dose by conventional radiotherapy, then to investigate the relationship between the changes of global longitudinal strain or cardiac magnetic resonance imaging and cardiac biomarkers and the certain cardiac substructure for stage N2-3 non-small cell lung cancer

In image-guided radiotherapy (IGRT), the repeated and increasingly intensive use of on-board positioning imaging, using 2D or 3D Mega-Volt (MV) or kilo-Volt (kV) imaging devices (cone-beam or CBCT scanners), is leading the international medical community to question the potential impact of these additional doses delivered to the patient, especially in at-risk populations such as children and young adults. The doses delivered to the patient by positioning imaging are still relatively unknown, due to the lack of experimental means and software available in clinical routine to easily and accurately evaluate these doses. The main objective is to estimate by personalized Monte Carlo calculation the physical doses delivered to the patient's organs by the onboard imaging systems during their radiotherapy treatment. The obtained imaging doses will be compared according to different irradiation scenarios commonly used in clinical routine as well as according to the treated location.

Since radiation dose escalation to a large volume of tumour inevitably will induce higher toxicity than is currently the case, efforts must be made to limit the volume of tissue irradiated. Moreover, the irradiation of larger tumour volumes leads to a lower achievable tumour dose when keeping the normal tissue doses constant. Central is thus the question whether it would be possible to limit the volume of tumour to be boosted by selectively escalating the radiation dose to specific disease sites which are theoretically more prone to relapse.

This study plan to enroll 852 patients with pulmonary nodules smaller than 3 cm in diameter, whose DNA and RNA will be extracted from mature red blood cells isolated from peripheral blood. The DNA 5-methylcytosine(5-mC) and RNA 2'-O-methylation information will be acquired by NGS and Nm Judge Universally sequencing (NJU-Seq), which will be used to establish models to distinguish patients with benign and malignant nodule in the training group and further evaluated in the validation group. The pathological results will be acquired after surgery or biopsy as standard in the study.

This study is a single-center, real-world and large-population-based retrospective study. In the current study, the investigators not only describe the changes of demographic and basic clinicopathological characteristics of lung cancer during recent years but delineate the correlation between clinicopathological features and common clinical blood tests in such a large population.

The role of this observational study is to access the feasibility of providing lung cancer screening using a designated nurse navigator through lung cancer screening clinic. Eligible participants will be identified using medical records, eligibility will be confirmed through phone call, screening visits will be scheduled as in-person visit or telehealth visit. Computed tomography screening will be performed at an approved center closer to the individuals place of living and results will be discussed during follow-up in-person visit or telehealth visit.

Aim 1 - Launch Pilot Study. In this aim, the investigators seek to launch a pilot study and enroll 12 eligible patients with advanced small cell lung cancer (SCLC) and to obtain the necessary tumor biopsies to yield sufficient DNA and RNA for Genome-Wide Sequencing (GWS). Aim 2 - Treatment Selection. Completion of this study aim will provide a new clinical paradigm in the treatment of SCLC such that each individual patient would be treated with a single-agent or combination therapy of commercially available agents that relates to particular target(s) that have been identified via GWS.

TITLE : Circulating tumor cells identification in advanced stage non-small cell lung cancer (CIRCUBRONCH) BACKGROUND : Circulating tumor cells identification is a new field of research in oncology, and some studies have been conducted with success on breast and prostate cancer. Nearly 80% of lung cancers are diagnosed in an advanced stage (IIIB, and IV). Circulating tumor cells identification and monitoring these cells after treatment could help the clinicians to detect relapse or be a prognostic factor. PRIMARY OBJECTIVE : Circulating tumor cells identification, and monitoring in advanced stage lung cancers (IIIB and IV). SECONDARY OBJECTIVES : Predictive value of the monitoring of circulating tumor cells on the therapeutic response. Prognostic value of identification of circulating tumor cells at the time of diagnosis. STUDY DESIGN : This study is a prospective, monocentrique trial analyzing the identification of circulating tumor cells in stage IIIB, and IV non-small cell lung cancers. Duration of the inclusions: 54 months. Duration of the study: 66 months. PROCEDURES : Detection of circulating tumor cells with CellSearch system (Veridex), and a cut-off of 5 cells/7,5 ml of blood. SAMPLE SIZE : 200 patients STATISTICAL ANALYSIS : Detection of circulating tumor cells is predicted in 20% of stage IIIB, and IV non-small cell lung cancers included in this study. The cut-off is 5 circulating tumor cells per 7,5 ml of blood.

The occurrence and progression of lung cancer is related to visceral adipose tissue (VAT). Epicardial adipose tissue (EAT) is a kind of VAT, producing a variety of inflammatory cytokines and adipokines, participating in the formation of local inflammation, promoting the formation of pre-thrombotic state, and leading to the occurrence of thromboembolism. Patients with lung cancer have increased inflammatory response and are more prone to suffer thrombosis. However, in lung cancer patients, the clinical correlation between EAT and pulmonary embolism has not been reported. Objective: To analyze the risk factors of poor prognosis in lung cancer patients with PE, and to explore the predictive value of EAT in pulmonary embolism events and death in lung cancer patients. Methods: EAT volume and density, as well as anthropometric and blood biomarkers, were evaluated in a sample of lung cancer patients, half with pulmonary embolism and half without. The incidence of adverse prognosis and related factors were followed up by telephone.

The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.
