Active clinical trials for "Lung Neoplasms"

The purpose of this study is to develop an ultra sensitive assay of mutation detection on circulating tumor DNA (ctDNA) for treatment, diagnosis and monitoring disease progression of Non-Small Cell Lung Cancer (NSCLC).

In addition to their role in allergic inflammation, mast cells are often found at the site of tumors. They have been attributed both to pro- and anti-tumorigenic roles depending on the tumor type. Secretion of mast cell mediators such as histamine, tryptase, fibroblast growth factor (b-FGF), vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) can enhance tumor growth and angiogenesis while TNF-a and heparin act as tumor suppressors. The non-small cell lung cancer constitutes the majority of cases of lung cancer. In lung cancer, mast cell numbers correlate with tumor angiogenesis and poor prognosis. In this work, we are interested to determine the factors in lung cancer microenvironment that attribute to mast cell activation. Beside the tumor cells themselves, the cancer microenvironment includes other cells such as fibroblasts. The fibroblasts arising from tumor stroma, called cancer-associated fibroblasts (CAFs), undergo activation, and have different feature compared to normal fibroblasts (NFs). In this work we are interested to determine whether CAF cells derived from lung tumors, together with the lung cancer cells, or microvesicles-derived from these cells, are able to stimulate mast cells to degranulate and/ or to release various cytokines and chemokines. For this propose, during surgery of patients with lung cancer, we will take unnecessary sample from the cancer and from normal area for purification of CAF or normal fibroblast cells. Those cells will be co-cultured with both lung cancer cell line (A-549) or microvesicles-derived from these cells, and human mast cell line (LAD2). Supernatants will be collected for determine degranulation and cytokine release from these mast cells.

A pilot study to observe satisfaction of analgesia with intercostal catheters after VATS lobectomy.

This observational study will evaluate the safety and efficacy of Tarceva (erlotinib) in routine clinical practice as second-line treatment in patients with recurrent or metastatic non-small dell lung cancer (NSCLC). Data will be collected from patients who have received 1 course of standard systemic chemotherapy, experienced disease progression, and who are receiveingTarceva in a second-line setting. Patients will also be followed through third-line treatment if there is disease progression on Tarceva therapy.

Lung cancer is one of the most deadly types of cancer and the leading cause of death in cancer in Sweden. Five year survival is 10% in men and 15% in women. Approximately 3300 individuals in Sweden are diagnosed each year and the incidence of adenocarcinoma is increasing. Lung cancer patients are to a great extent currently being diagnosed by exfoliative cytology. However, new drugs leading to more personalized treatments will demand more specific classification of tumour types. Today EGFR mutation status is becoming an important factor when deciding treatment strategy for patients with Non-Small Cell Lung cancer. Sufficient tumour material must be available if EGFR mutation status is to be tested. Core needle biopsy is one way to obtain the quantity of material needed when testing mutation status. The portion of patients having core needle biopsies is believed to vary greatly between hospitals in Sweden, a difference from 20% to 70 % have been assumed, but is not yet confirmed in studies. This study will investigate the current situation and procedures when patients are diagnosed with lung cancer. The results can be used to describe any possible adverse events connected to the procedure and possibly contribute to development of a better decision tool to be used when deciding if a core needle biopsy is to be performed or not. More and more therapeutical targets having similar problems are likely to be developed in the future. An investigation of current quality and procedures when diagnosing lung cancer by biopsies will facilitate future diagnosing of lung cancer and ensure that personalized treatments can be offered to patients.

RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in tissue and blood samples from patients with early-stage non-small cell lung cancer.

Metabolism and DNA adduct formation are critical in cancer induction by NNK. The investigators goal is to understand whether the observed ethnic/racial differences in lung cancer incidence are due to variations in NNK metabolism. The investigators overall hypothesis is that cancer susceptibility relates to carcinogen dose and to the balance between carcinogen metabolic activation and detoxification. The investigators propose to test this hypothesis via investigation of potential differences in NNK metabolic activation and detoxification in African American and European American smokers.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in blood samples from patients with refractory non-small cell lung cancer previously treated with sorafenib tosylate.

The purpose of the research study is to develop a new, more sensitive, and less invasive test for diagnosing lung cancer at an earlier stage, when it can more easily be cured. The investigators hypothesize that certain genes are expressed differently in current and former smokers who have lung cancer, and this difference in gene expression may be a biomarker for lung cancer.

Objectives: Evaluation of an amplitude based gated Positron Emission Tomography (PET) data acquisition system for all GE Discovery Positron Emission Tomography/ Computed Tomography (PET/CT) scanners.
