Active clinical trials for "Bronchial Neoplasms"

Identify the best combination of predictive variables that influence ionizing radiation dose and improved image quality through analysis and quantification of PET-CT images in simulators and patients.

Study of the modification of the fixation(binding) of Fluoro-2-deoxy-D-glucose (FDG), fluoro-misonidazole (FMISO) and 3'deoxy-3-fluoro-thymidine deoxy-3-fluoro-thymidine (FLT) measured in tomography by broadcast(emission,issue) of positrons (PET) at patients before and in the course of exclusive radiotherapy or concomitant radiochemotherapy for primitive bronchial cancer. This protocle allows to study the simultaneous variations of the metabolism, the hypoxie and the cellular proliferation by PET SCAN at 5 patients reached(affected) by a primitive bronchial cancer in the course of exclusive radiotherapy for primitive bronchial cancer not small cell lung. The investigators are also going to study several scenarii of optimization of the radiotherapy according to the variations of the tumoral metabolism, the hypoxie and the cellular proliferation measured in the course of radiotherapy (theoretical study on console using the scanner and the various examinations).

A multi-centre observational, non-interventional study is to dynamically monitor the changes of circulating tumor DNA (ctDNA) in late stage NSCLC patients under Gefitinib treatment.
