Texto completoInitial diagnosis and monitoring of bladder cancer is mainly based on cystoscopy, an invasive examination combined with urine cytology, which has limited sensitivity, especially in the early stages of this cancer. The need for non-invasive tests with improved sensitivity has led to the exploration of urine-based biomarker testing. Despite numerous advancements, no urine-based test is currently recommended for routine clinical use due to the complexity of use, performance, or cost. Vibrational analysis of urine using infrared absorption spectroscopy is an interesting approach for developing an easy-to-use, relatively inexpensive, and clinically applicable urine test. In this thesis, the diagnostic performances of this technique, combined with machine learning tools, were evaluated using urine samples from patients consulting the Urology Department of the Reims University Hospital. Despite the high spectral variability of urine samples, the combined optimization of spectral pretreatments and classification model parameters yielded promising results. Meanwhile, algorithmic developments have been developed to include clinical data, offering a way to improve the performance of these techniques in future investigations

Texto completoThe work reported in this thesis focuses on the development of a multiplex analytical tool for the quantification of selected bladder cancer urinary biomarkers.The aim of the first part of this work is the selection of urinary biomarkers for the diagnosis and recurrence of urothelial tumors. A first study evaluated the selectivity of candidate markers in urine samples of bladder cancer patients. Five of the twenty initial markers were selected for their diagnostic performance. They define Panel 1: VEGF, MMP9, IL8, PTGS2 and EN2. A second study was then conducted to assess the potential of urinary markers and clinical parameters for the diagnosis of bladder cancer recurrence. Two types of urine samples were thus evaluated: samples from recurrent bladder cancer patients and samples from bladder cancer patients without recurrence. Panel 2 was then defined based on the best performing multivariate regression model. It includes the following clinical and molecular parameters: number of past recurrences, number of BCG therapies, tumor stage at diagnosis, CDH1, IL8, ErbB2, IL6, EN2 and VEGF.The second part involves the development of a multiplex test for the quantification of the selected markers. It is a high-throughput automated platform in a 96-well microtiter plate format. It was designed as a multiplex sandwich immunoassay based on a protein microarray. The platform development began with Panel 1 for which three of the five markers (VEGF, MMP9 and IL8) were successful integrated into a multiplex immunoassay. The end of the second marker selection study marked the development transition from Panel 1 to Panel 2. With the exception of EN2, requiring a different immunoassay configuration, all the Panel 2 markers were integrated into the platform

Texto completoMRI is an increasingly important imaging modality for prostate cancer diagnosis. Further indications are being validated in prostate cancer to establish the prognostic, to guide treatment and to follow up patients especially after partial treatment. The first part of this work has focused on clinical studies of MRI in patient selection for active surveillance. The performance of MRI particularly in the detection of anterior cancers would reduce the risk of initial underestimation of tumor burden and therefore reduce the risk of reclassification during active surveillance protocols. The second part of this work has focused on the correlation between the signal abnormalities on MRI and intra-prostatic areas. We used a simple and reproducible technique for MRI and histopathology registration and we correlated signal abnormalities recorded on MRI with quantitative histopathological parameters at prostatectomy surgical specimens

Texto completoThe work reported in this thesis focuses on the development of new multiplex analytical devices on biochip or electrode microarray format, dedicated to diagnosis and environmental monitoring. The objective of the first research axis is diagnosis, thanks to the detection in patients’ serum of a panel of antibodies, biomarkers of a pathological state. For that purpose, two immunotests have been developed, enabling the multiparametric detection of specific antibodies by automated and high-throughput analysis of serum samples. This approach is based on the antibodies capture by antigens probes immobilized in a matrix of spots on a membrane surface composing the wells bottom of a micro-titer plate. Enzyme-labeled antibodies have been used, providing a colorimetric detection. This device enabled the achievement of the analysis of 96 samples in less than three hours and has been applied to different applications. The first one consists of allergy diagnosis, and the second focuses on cancer diagnosis. The second part of this work is applied to environmental monitoring, through water analysis. Different types of pollutants have been defined as targets: pesticides, toxins and explosives. In order to integrate them in a matrix of probes, different conjugates have been synthesized with these haptens. After screening and optimization of the conjugates through their reactivity and cross-reactivity with the specific antibodies, the developed device demonstrated his analytical performances in terms of sensitivity and selectivity. Finally, for the European Project BONAS, a last sensor based on water analysis has also been developed. This electrochemical microarray aims to detect explosives precursors, used in improvised explosive devices, for the localization of hidden bomb factory. The chip was designed as a screen-printed electrode network, which was modified by different metals electrodeposition

Texto completoThis work describes a mosaicing algorithm for constructing panoramic images of internal walls of the bladder. Time relating to the construction of panoramic images including the interesting parts must be shorter than that required by a standard cystoscopic examination. The mosaicing algorithm must be robust against lighting conditions, morphologic and texture variations relating to instruments and patient anatomy. These panoramic images could be used by a clinician for guiding further exams, storing non-redundant data and following-up evolution of lesions. The preprocessing of cystoscopic images is the first stage of the algorithm. Preprocessing consists of shading correction and fiber optics pattern attenuation occurring in fiberscope acquired images. The second stage is image registration. The chosen solution consist of cross-correlating images (using their Fourier transforms) in order to have initial translations for an iterative registration algorithm based on the sum of squared differences of images. In the third stage, images are projected in the coordinate system of the panoramic image using global transformations computed with matrices given by the iterative registration. We use a weighted average of pixel intensities to blend visible borders of images produced in the projection process. Numerical results obtained with a phantom and qualitative results obtained with real sequences show that our automatic approach is robust and allows for a fast construction of panoramic images in a period of time that is shorter than the duration of a clinical cystoscopic examination. Our experiments showed that the registration algorithm can handle geometric transformations that are larger than those existing typically in a video-sequence (90% of superposition between successive images in this case)

Texto completoThe aim of this thesis is to facilitate bladder cancer diagnosis. The reference clinical examination is cystoscopy, where an endoscope, inserted into the bladder, allows to visually explore the organ's internal walls on a monitor. The main restriction is the small field of view (FOV) of the instrument, which complicates lesion diagnosis, follow-up and treatment traceability.In this thesis, we propose robust and accurate algorithms to create two- and three-dimensional large FOV maps from cystoscopic video-sequences. Based on recent advances in the field of discrete energy minimization, we propose transformation-invariant cost functions, which allow to robustly register image pairs, related by large viewpoint changes, with sub-pixel accuracy. The transformations linking such image pairs, which current state-of-the-art bladder image registration techniques are unable to robustly estimate, are required to construct maps with several overlapping image trajectories. We detect such overlapping trajectories automatically and perform non-linear global map correction. Finally, the proposed energy minimization based map compositing algorithm compensates small texture misalignments and attenuates strong exposure differences. The obtained textured maps are composed by a maximum of information/quality available from the redundant data of the video-sequence. We evaluate the proposed methods both quantitatively and qualitatively on realistic phantom and clinical data sets. The results demonstrate the robustness of the algorithms, and the obtained maps outperform state-of-the-art approaches in registration accuracy and global map coherence
