Full textIndividualized margins in radiotherapy planning of lung cancer: analysis of physiological movements and their dosimetric impacts OBJECTIVE: This study is an analysis of physiological movements and their dosimetric impacts when a single thoracic CT-scan is used for treatment planning purposes in radiation oncology. METHODS: This is a study of 15 patients. Three-dimensional conformal radiation therapy was (3D-CRT) was used. A reference clinical plan was constructed and compared with plans using individualized margins (obtained by using five CT-scans). Volumetric and dosimetric analyses were made for each. RESULTS: The total volume occupied by GTV progressed quickly with the fusion of CT-scans. For a similar coverage, target volume was smaller and lung irradiation was slightly decreased. CONCLUSIONS: Even if the individualized margin was used, it produced a limited clinical advantage. All techniques that increase total volume with an aim to include more movements should come to similar conclusions.

Full textA major challenge in lung cancer treatment in radiotherapy is to take into account organs movements and deformations in order to improve dose coverage of the tumor and spare the surrounding healthy tissues. We focused on intensity based deformable registration methods applied to 3D computed tomography scans (3D-CT) of the thorax. The goal is to extract movement and deformation information of lungs and tumor. During this PhD we developed a deformable registration platform with multiples regularizations techniques of vector fields. We did three main studies. In the first one we used deformable registration to study the breath-hold reproducibility with ABC device. The breath-hold was efficient for patients with normal lung behavior and inefficient for patients with lung discrepancies. In the second study, we used 4D-CT acquisitions (a 4D-CT acquisition is a set of 3D-CT images acquired over the free-breathing respiration cycle). The goal was to extract and follow thorax movements for a free-breathing treatment and 4D dosimetric studies. We built a first 4D-CT image model with two 3D-CT images acquired at end-inhale and end-exhale stages of the respiration cycle. The long-term goal is to have a complete model of lung and thorax, allowing tumor tracking and respiration synchronized irradiation, in order to optimize the lung cancer treatment in radiotherapy

Full textThe tumour blood vessels are immature and dysfunctional, limiting the distribution and efficacy of anticancer drugs. Conventional radiotherapy (2Gy / day) improves their structure, reduces hypoxia and improves the biodistribution of concomitant treatments. However, hypofractionated radiotherapy, using higher doses per fraction, tends to replace conventional schedules. Their consequences on the tumour microenvironment are poorly understood. Our goal was to define the impact of different fractionation schedules on the tumour vascular microenvironment. A fractionation scale, ranging from 2 to 12Gy per fraction, was implemented on two cancer models (prostate and lung). Several phenotypical and functional aspects of the vasculature and anti-tumour efficacy were studied. A radiation-induced vascular maturation was observed, including an increased pericyte coverage and an improved distribution of doxorubicin. In both models, tumour control was better for hypofractionated schedules. Vascular pseudo-normalization was poorly sensitive to fractionation, but hypoxia was improved in a dose-dependent manner. The depth and duration of the improvement was greater in the slow-growing prostate cancer model: hypoxia seemed to depend as much on the kinetics of repopulation of the model as on the quality of the blood supply. Our results highlight the mutual influence of tumour and vascular responses to irradiation. They will be useful to optimize the future delivery schedule of anticancer treatments

Full textThe thoracic radiotherapy is complex du to the presence of great thicknesses and very sensitive organs. It profited from advanced conformal radiotherapy and breathing control. The dosimetric validation of clinical conditions, using anthropomorphic phantoms, consisted in simulating three types of target volumes, three photons quality index, three lung volumes densities and the irradiation with intensity modulation. The measurements, using radiochromic films, helped to evaluate the algorithm used, for configurations close to the treatments conditions. Recommendations, resulting from this work, relate to the choices of quality index, analytical calculation in the presence of low densities, dosimetric validation methods and the practice of intensity modulated

Full textA computed tomography (CT) represents the 3D map of the linear attenuation coefficients of a X-ray beam. If the patient breath and the motion is not taken into account, the CT images of the thorax are disturbed by strong artifacts such as blur, streaks and bands. The objective of this thesis is to propose methods to correct these artifacts and to apply them in the context of the radiotherapy of the lung cancer to sequences of cone-beam projections acquired with a CT scanner mounted on the gantry of a linear accelerator. The first method uses a respiratory signal to select for the reconstruction the projections corresponding to a same phase. To apply it, we proposed a method to extract automatically the respiratory signal from the cone-beam projections. A quantitative analysis was then performed on simulated data to evaluate the impact of the reconstruction algorithm and of the different selection parameters of the cone-beam projections. We obtain thus CT images without blur but with a quality limited due to the small number of projections used. Other approaches modify the reconstruction algorithm to compensate for the respiratory motion using a realistic model, which allows to use all the acquired projections. We proposed two motion compensated reconstruction methods. The first one is analytic and based on a heuristic. The second one solves the problem algebraically from a discrete formulation of the transformations at stake via two new approaches, one forward and the other backward
