Filter by:There is a possible implication of sleep apnea syndrome via night-time intermittent hypoxemia in perturbation of quality of life and tumour progression to patients with a bronchial cancer. The aim of the study is to evaluate this possibility with the help of a night record of sleep and quality of life questionnaires.
Diagnose lung cancer at an early stage is crucial for effective treatment. At these early stages, cancer is usually invisible in ambient white light when the endoscopic analysis of the bronchial mucosa. This lining is self-fluorescent at its illumination by blue light. These widely distributed autofluorescence methods detect early mucosal abnormalities. They are very sensitive but not specific to recognize the lung cancer. Thanks to European funding (EURIMUS), a new tool with fluorescent UV light has been developed. The purpose of this preliminary study is to verify the suitability for specific detection of cancerous tissue in Pneumology of this fluorescence method versus histological analysis of the tissue.
The purpose of this study is to determine whether 18F-Al labeled RGD is safety and effective for cancer diagnosis and therapy response.
In this study it will be analyzed how often the sleep apnea syndrome can be observed in patients with newly diagnosed lung cancer with the help of ApneaLink device by ResMed.
Gefitinib was the first epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) approved for the treatment of advanced non-small cell lung cancer (NSCLC). Results from two randomised phase II trials (IDEAL 1 and 2) suggested that gefitinib was efficacious and less toxic, compared with previous results, than was chemotherapy in patients with previously-treated non-small-cell lung cancer. Two phase III trials of gefitinib in advanced non-small-cell lung cancer followed on from the IDEAL phase II studies: Iressa Survival Evaluation in Lung cancer (ISEL) and Iressa NSCLC Trial Evaluating REsponse and Survival versus Taxotere (INTEREST). Although the phase III ISEL trial failed to prove the superiority of gefitinib treatment compared to placebo in previously treated patients, a subgroup analysis demonstrated improved survival in particular populations (Asians and non-smokers). The INTEREST study compared an EGFR tyrosine kinase inhibitor with chemotherapy in pretreated advanced non-small-cell lung cancer. In INTEREST, survival was similar for gefitinib and docetaxel in almost all subgroups; no EGFR-related biomarker or any clinical factor (including female sex, adenocarcinoma histology, never-smoker, and Asian ethnicity) appeared to be predictive of a greater survival benefit for gefitinib versus docetaxel. However, these factors may still be predictive of a greater survival benefit for gefitinib and/or docetaxel versus best supportive care; alternatively, they may just be good prognostic factors. Progression free survival and overall response rate was no statistically significant difference between gefitinib and docetaxel. This suggests gefitinib can provide similar overall survival to docetaxel in pretreated advanced non-small-cell lung cancer patients. These studies have demonstrated that gefitinib is effective for the second-line treatment of NSCLC. Now, gefitinib is recommended in advanced and metastatic NSCLC as second-line chemotherapy. But, there was no prospective study with gefitinib in NSCLC wih squamous cell histology. This trial will investigate the efficacy and safety of gefitinib in locally advanced, metastatic NSCLC patients with squamous cell histology who have failed first-line chemotherapy.
The knowledge concerning the biology of the human tumors do not stop widening, in particular concerning the molecular mechanisms at the origin of the process of carcinogenesis and its ability to become perpetual. The identification and the increasing knowledge of these abnormalities allowed during these last years the development of therapeutic strategies targeting specifically the molecular pathways involved in the carcinogenesis. It quickly lead to numerous therapeutic successes in association with conventional chemotherapy, allowing a better individualization of the treatment according to the biological characteristics of the tumor of the patient. However such therapeutics are effective only if the patients carries specific genomic mutations making necessary the systematic research for one kind of mutation. The problem is that currently the mutational status is frequently made on the tissue resulting from the initial tumor biopsy, and as it is not excluded that the evolution of the biology of the metastasis reports a different genomic status, the only theoretical solution is then to make biopsy systematically on metastasis, what is not always technically possible. The problem still complicates when the investigators know that the biology of the tumor may evolve in time, particularly under treatment, with appearance of chemotherapy resistant clones. The monitoring of the genomic status of the tumor thus appears to be a crucial stake in the next years in cancer research as far as the efficiency of numerous therapeutic targeted put at the disposal of the clinician, depends on it largely. The repeated access to tumor tissue, during the follow-up of the patient in treatment, seems from then on indispensable to guide prematurely the therapeutics, in particular by stopping a targeted therapeutics which the investigators know that it is not any more going to be effective, and so avoiding exposing the patient to useless toxicity of a treatment often extremely expensive, and of which usage should have to be reserved to patient who could respond to it. The access to the circulating tumor cells in the blood of patients is a repeatable, not invasive technique (blood test) and henceforth accessible thanks to a technique using a magnetic sorting of the tumor cells selected by an antibody directed against the tumor antigen EpCAM. This new technology (CellSearch, Veridex system) totally standardized and automated, allows from a total sample of blood of the patient, to determine the quantity of circulating tumor cells (CTC).The number of CTC seems to constitute in recent studies, a powerful prognosis tool at the moment diagnosis, but also during treatment, according to its decrease or not under chemotherapy. In United States, the Food and Drug Administration (FDA) recently approved the use of this system for the quantification of the CTCs in the care of the patients affected by breast, colon, and prostate cancer. The CellSearch system will probably become in the future years an indispensable tool to help the clinicians to encircle better the prognosis of their patient. This technology already allows to realize besides a quantification, the isolation of viable CTCs, from which the genetic material can be extracted, amplified thus potentially analyzed. The investigators thus see all the interest which such a device can represent in the non invasive monitoring of the patients under treatment targeting molecular abnormality susceptible to evolve in time. The investigators thus propose to study thanks to the system CellSearch the feasibility of the research for the mutation of K-Ras and EGFR in the CTC of patients carriers of a metastatic non small cells bronchial carcinoma. Secondly, the investigators research will be interested in the possible conflicts existing between the primitive tumor and the CTCs for the various popular mutations. In case of feasibility of the method, and the good initial concordance between the genomic status of the CTCs and that of the tumor, the investigators shall describe the genomic evolution under treatment monitoring the CTCs of the patients under targeted therapeutics. The investigators shall describe then if the premature observation of modification precedes the appearance of an effective resistance in treatments.
In this Phase II clinical trial the investigators will use four human non-small cell lung cancer cell lines that have been previously established in tissue culture laboratory. The investigators will gene modify these tumor cells in the laboratory to block their TGF-beta secretion. The investigators will inject the genetically engineered cells as vaccines in patients with stages II to IV non-small cell lung cancer. Our rationale for using other people's tumor cells is that lung tumor cell lines belonging to different people have been shown to share common characteristics that are recognized by non-self immune systems.
In the UK, staging of lung cancer is time consuming (taking on average more than 3 weeks), costly and inaccurate in up to 20% of cases. The investigators wish to determine whether using the newer techniques of endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS) improves lung cancer staging. The investigators' hypothesis is that EUS (endoscopic ultrasound) or EBUS (endobronchial ultrasound guided transbronchial needle aspirate) as a first test after CT scan in the diagnosis and staging of lung cancer will result in a reduction in the time from first outpatient appointment to treatment decision, a reduction in the total number of scans and investigative operations, fewer outpatient attendances and a reduction in healthcare costs.
