Abstract:
Purpose: To evaluate the feasibility and accuracy of intracavitary electrocardiogram for verifying tip position of peripherally inserted central catheters in cancer patients during follow-up period. Methods: From March 2015 to October 2015, 126 patients involved in eight hospitals who underwent peripherally inserted central catheter placement received intracavitary electrocardiogram and chest X-ray to verify position of the catheter tip during follow-up period. Their intracavitary electrocardiogram was compared with surface electrocardiogram to judge catheter tip landing zone in one of three different anatomical zones. The amplitude of intracavitary electrocardiogram P wave and the ratio of intracavitary electrocardiogram P wave/surface electrocardiogram P wave were measured and showed correlation with catheter tip position confirmed by chest X-ray. Based on chest X-ray principle, all the cases were assigned into three intracavitary electrocardiogram groups to explore the optimal cut-off values for intracavitary electrocardiogram P wave and intracavitary electrocardiogram P wave/surface electrocardiogram P wave by analyzing the receiver operating characteristic. Results: No technique-related complications or adverse events occurred in this study. The matching rate between intracavitary electrocardiogram and chest X-ray method was 93.7%. The optimal cut-off values for intracavitary electrocardiogram P wave were set from 3.15 to 3.75 mV, and intracavitary electrocardiogram P wave/surface electrocardiogram P wave from 1.65 to 3.25. Conclusions: It is demonstrated in this retrospective multicenter study that the intracavitary electrocardiogram method for verifying tip position of peripherally inserted central catheter during follow-up period is feasible and accurate in all adult patients with cancer.

Abstract:
Introduction. L’efficacité de la chimiothérapie intracavitaire dépend de la pénétration du produit au sein du péritoine (CHIP) ou de la plèvre. L’hyperthermie et l’hyperpression peuvent augmenter cette pénétration. Ce travail étudie leur effet intrapéritonéal, puis établit la méthode optimale pour les délivrer. L’étude de la faisabilité et de la tolérance d’une hyperpression intrapleurale est essentielle pour transposer ces bénéfices à la cavité thoracique. Méthodes. Quatre groupes de porcs ont reçu une CHIP ouverte avec de l’oxaliplatine à une concentration constante (150 mg/l) pendant 30 minutes en normothermie ou hyperthermie (42-43°C) ; et en pression atmosphérique ou hyperpression (25 cmH2O). Deux groupes ont reçu une procédure fermée en hyperthermie et hyperpression ou forte hyperpression (40 cmH2O). L’absorption systémique et tissulaire d’oxaliplatine a été étudiée. La tolérance d’une perfusion pleurale a été étudiée chez 21 porcs avec ou sans résection associée, avec ou sans chimiothérapie (cisplatine + gemcitabine), à divers niveaux de pression de 15 à 25 cmH2O. Résultats. L’hyperthermie augmente les concentrations de platine dans les surfaces viscérales (p=0.0014), alors que l’hyperpression l’augmente dans les surfaces viscérales et pariétales (respectivement p= 0.0058 et p= 0.0044). L’association des deux facteurs permet d’obtenir les concentrations les plus importantes dans le péritoine viscéral (p= 0.00001) et pariétal (p= 0.0003). Les concentrations obtenues lors des procédures fermées sont inférieures à celles obtenues en ouvert, même lorsque la pression atteint 40 cmH2O. Une chimiothérapie intrapleurale à 20 cmH2O sans résection associée est le niveau maximal toléré durant 60 minutes. Conclusion. Au cours d’une CHIP, l’hyperthermie augmente la pénétration d’oxaliplatine dans le péritoine viscéral, alors que l’hyperpression est efficace dans le péritoine viscéral et pariétal. Leur association est synergique et la procédure ouverte semble la meilleure pour la délivrer. Une chimiothérapie intrapleurale est faisable à 20 cmH2O dans ce modèle
Introduction. In order to achieve a good effect, chemotherapy drugs need to penetrate into the peritoneal (HIPEC) or pleural tissue. Hyperthermia and high-pressure may enhance this penetration. The aim of this study was to evaluate their peritoneal effect and to establish the best technique to it. A feasibility study of an intrapleural high-pressure was an essential step to export these effects to the thoracic space. Methods. Four groups of pigs underwent an open HIPEC with a constant concentration (150 mg/l) of oxaliplatin during 30 minutes either in normothermia, or in hyperthermia (42-43°C); and either with atmospheric pressure or with high-pressure (25 cmH2O). Two more groups underwent a closed procedure with hyperthermia and either high-pressure or very high-pressure (40 cmH2O). The systemic and tissue absorption of oxaliplatin were studied. The haemodynamic and respiratory tolerance of a pleural infusion was also tested in 21 pigs with and without associated resection; with and without chemotherapy infusion (cisplatin + gemcitabin) and at various levels of pressure (from 15 to 25 cmH2O). Results. Hyperthermia enhances the concentrations of platinum in visceral surfaces (p=0.0014), whereas high-pressure enhances it both in visceral and in parietal surfaces (p= 0.0058 and p= 0.0044, respectively). Their association obtains the highest concentrations both in the visceral (p= 0.00001) and the parietal peritoneum (p= 0.0003). The concentrations obtained during closed procedure are lower than those achieved with the open technique, even with 40 cmH2O of pressure. A 60-minutes intrapleural chemotherapy perfusion with 20 cmH2O of pressure without any lung resection was the maximal tolerated level. Conclusion. During HIPEC, hyperthermia improves the penetration of oxaliplatin in the visceral peritoneum, whereas high-pressure is effective in both peritoneal surfaces. Their association is synergic and the open technique seems to be the best one to deliver it. An intrapleural chemotherapy with a 20 cmH2O pressure is feasible in this model

Le travail présenté dans cette thèse concerne l'étude, la réalisation et la caractérisation des sondes ultrasonores pour le traitement des tumeurs cancéreuses vaginales, prostatiques ou du rectum; par hyperthermie intra cavitaire. La première partie présente l'approche théorique des caractéristiques des différentes céramiques utilisées. Nous avons étudié le rendement, l'impédance électrique et le circuit électrique équivalent. Un algorithme, utilisant la méthode d'intégration de Simpson, permet le calcul numérique du diagramme de rayonnement. La deuxième partie présente la méthodologie et les résultats expérimentaux. La distribution spatiale de l'intensité acoustique dans l'eau et le glycérol a été mesurée par un détecteur piézo-électrique de petite taille. Ainsi la directivité et la profondeur de pénétration des faisceaux ultrasonores ont été déterminées. Il est montré qu'une vobulation permet d'améliorer l'homogénéité du faisceau sur toute son ouverture. Ainsi ont été étudiées les variations des gradients thermiques dans l'espace, en fonction du temps et de la puissance d'émission. Le refroidissement des applicateurs en surface permet de produire un échauffement en profondeur.

Abstract:
La curiethérapie est une technique ancienne utilisant des sources scellées de faible ou moyenne énergie, toujours pertinente aux plans thérapeutique et économique et toujours en évolution (e.g. curiethérapie à Haut Débit de Dose (HDD)). Cette modalité de traitement permet de délivrer une forte dose d'irradiation dans un volume-cible limité, et permet de minimiser le risque de cancer radio-induit en préservant les Organes à Risques (OAR). Cependant, elle génère des gradients de dose élevés rendant la dosimétrie in vivo délicate à mettre en oeuvre. Les écarts constatés entre doses délivrées et prescrites sont ainsi fréquemment supérieurs à l'écart maximal toléré par la réglementation (± 5%) en usage pour la radiothérapie externe conventionnelle et rendue obligatoire en France par décret depuis 2011. Ce travail de thèse s'est déroulé dans le cadre du projet ANR-TECSAN INTRADOSE et exploite les acquis technologiques antérieurs démontrés à l'issue du projet Européen MAESTRO et du projet ANR-TECSAN CODOFER, en particulier une instrumentation RL/OSL (Radioluminescence - Optically Stimulated Luminescence) multivoies réalisée et validée au plan préclinique dans le cadre du projet MAESTRO. Le projet INTRADOSE a pour objectif de démontrer la faisabilité d'une Dosimétrie In Vivo (DIV) intracavitaire par cathéter dosimétriques à fibres optiques et cristaux d'alumine Al2O3:C dans le but d'améliorer la sécurité des patients traités par Curiethérapie HDD. Ce nouveau type de détecteur permet de mesurer une distribution de doses (mulitpoints) proche des OAR, il présente un petit diamètre (
The brachytherapy is an old technique using sealed radioactive sources of low or average energy. This technique is still therapeutically and economically relevant today and always evolving (e.g. High Dose Rate (HDR) brachytherapy). This treatment enables to deliver a high dose of irradiation in a limited tumoral volume and enables to minimize the risk of radiation-induced cancer as preserving the Organs at Risks (OAR). However, this technique generates high dose gradients, which makes in vivo dosimetry difficult to implement. Hence, the deviations observed between doses delivered and prescribed are often up to the maximal deviation tolerated by the nuclear safety regulations (± 5%) in conformational radiotherapy. Those regulations have been made mandatory in France since 2011. This thesis has been done within the framework of the ANR-TECSAN INTRADOSE project and is based on the past technological benefits demonstrated during the MAESTRO European project and the ANR-TECSAN CODOFER project, in particular a RL/OSL multichannel instrumentation (Radioluminescence - Optically Stimulated Luminescence) made and validated in preclinical evaluation during the MAESTRO project. The purpose of the INTRADOSE project is to demonstrate the feasibility of the intracavitary In Vivo Dosimetry (IVD) by dosimetric catheter using optical fibers and alumina crystals Al2O3:C with the aim of improving the safety of patients treated by HDR brachytherapy. This new probe enables to measure a dose distribution (several points) close to the OAR, it offers a little diameter (

Abstract:
Les tumeurs cérébrales primitives de haut grade représentent un enjeu de soins depremière importance. En effet, les plus fréquentes d’entre elles ; les glioblastomes (GBM) sont incurables. Leur médiane de survie est d’une quinzaine de mois lorsque les patients ont bénéficié d’une chirurgie d’exérèse optimale suivie des traitements adjuvants recommandés que sont la radiothérapie et la chimiothérapie. Malgré ces traitements, la récidive est la règle,et ce la plupart du temps à proximité de la cavité d’exérèse initiale. De nouvelles techniques ont vu le jour afin d’améliorer le contrôle local de la tumeur, citons l’implantation des pastilles de carmustine au sein de la cavité chirurgicale. Toutefois le bénéfice de ce type de thérapeutique complémentaire reste limité.C’est dans ce contexte que l’idée d’appliquer la thérapie photodynamique (PDT) aux GBM a émergé. Ce traitement repose sur la présence synchrone de trois éléments : une molécule photosensibilisante, de l’oxygène et l’illumination à une longueur d’onde spécifique déclenchant une cascade métabolique favorisant la mort des cellules gliales cancéreuses.Grâce au développement de photosensibilisant plus spécifique des cellules cancéreuses (PpIX 5-ALA), et notamment gliales, la thérapie photodynamique cérébrale apparaît comme une thérapie additionnelle prometteuse, ayant potentiellement un effet synergique avec les traitements adjuvants recommandés.Dans le cadre de GBM opérables, la PDT intracavitaire a pu être évaluée par notre équipe lors d’un essai clinique de phase I (INDYGO), démontrant sa sécurité d’usage et confirmant des résultats oncologiques encourageants. L’évaluation de la dose de lumière optimale permettant de traiter plus en profondeur reste à réaliser. Un essai de phase II(DOSYNDIGO) y est dédié et est en cours de période d’inclusion.Toutefois, certaines lésions de par leur topographie ne peuvent être opérées sans engendrer des déficits neurologiques permanents et péjoratifs pour le pronostic du patient.L’absence de chirurgie d’exérèse initiale grève d’autant plus le pronostic ultérieur de la maladie en réduisant la période de survie sans progression et survie globale. Dans le cas des patients ne pouvant bénéficier d’une chirurgie d’exérèse, la PDT intracavitaire ne pouvait avoir lieu.C’est dans ce contexte que nous avons mené nos travaux de recherche en direction de la PDT interstitielle (iPDT). Ce traitement minimalement invasif consiste en l’introduction d’une ou plusieurs fibres optiques en conditions stéréotaxiques au sein de la tumeur ou à proximité immédiate afin de délivrer l’illumination requise sans réaliser de craniotomie ni de dissection du parenchyme cérébral. L’iPDT pourrait être indiqué pour les patients nouvellement diagnostiqués non opérables, mais aussi à la récidive. L’iPDT viendrait en complément des standards de soins, sans les modifier. Nous avons rapporté les données de la littérature concernant l’iPDT, puis nous avons proposé des données originales décrivant une procédure clinique standardisée basée sur un algorithme dosimétrique dédié, avant d’entrevoir un essai clinique de phase I
High-grade primary brain tumors represent a major care issue. Indeed, the mostfrequent of these tumors, glioblastoma (GBM), have an appalling prognosis. Their mediansurvival is about 15 months when patients have undergone optimal excision surgery followedby the recommended adjuvant treatments of radiotherapy and chemotherapy. In spite of thesetreatments, recurrence is the rule, and most of the time close to the initial excision cavity. Newtechniques have been developed to improve local control of the tumor, such as the implantationof carmustine wafers in the surgical cavity. However, the benefit of this type of complementarytherapy is limited.It is in this context that the idea of applying photodynamic therapy (PDT) to GBM hasemerged. This treatment is based on the synchronous presence of three elements: aphotosensitizer molecule, oxygen and illumination at a specific wavelength triggering ametabolic cascade promoting the death of cancerous glial cells. Thanks to the development ofphotosensitizers specific to cancer cells (PpIX 5-ALA), especially glial cells, brain PDT appearsto be a promising additional therapy, potentially having a synergistic effect with gold-standardadjuvant treatments.In the context of operable GBM, intracavitary PDT has been evaluated by our team ina phase I clinical trial (INDYGO), demonstrating its safety and confirming encouragingoncological results. The evaluation of the optimal light dose for deeper treatment remains tobe done. A phase II trial (DOSYNDIGO) is dedicated to this and is currently in the inclusionperiod.However, some lesions, because of their topography, cannot be operated on withoutcausing permanent neurological deficits that are disabling for the patient prognosis. Theabsence of initial excisional surgery further compromises the prognosis of the disease byreducing the period of progression-free survival and total survival. In patients who could notbenefit from excisional surgery, this additional intra-cavity treatment could not take place. Thisis why we conducted our research work towards interstitial PDT. This involves introducing oneor more optical fibers under stereotactic conditions into the tumor or in its immediate vicinity inorder to deliver the required illumination without performing a craniotomy or dissecting thebrain parenchyma. This minimally invasive treatment represents a real opportunity for allpatients who cannot be operated on, either at the initial diagnosis of their GBM or at recurrence.This interstitial treatment would complement standard of care without modifying it. We reportedthe current data regarding iPDT available in the literature, then we proposed original data witha standardized clinical procedure based on a dedicated dosimetry algorithm, before lookingforward to a phase I clinical trial

Abstract:
Las señales electrocardiográficas, ya sea adquiridas en la piel del paciente (electrocardiogamas de superficie, ECG) o de forma invasiva mediante cateterismo (electrocardiogramas intracavitarios, iECG) ayudan a explorar la condición y función cardíacas del paciente, dada su capacidad para representar la actividad eléctrica del corazón. Sin embargo, la interpretación de las señales de ECG e iECG es una tarea difícil que requiere años de experiencia, con criterios diagnósticos complejos para personal clínico no especialista, que en muchos casos deben ser interpretados durante situaciones de gran estrés o carga de trabajo como en la unidad de cuidados intensivos, o durante procedimientos de ablación por radiofrecuencia (ARF) donde el cardiólogo tiene que interpretar cientos o miles de señales individuales. Desde el punto de vista computacional, el desarrollo de herramientas de alto rendimiento mediante técnicas de análisis basadas en datos adolece de la falta de bases de datos anotadas a gran escala y de la naturaleza de “caja negra” que están asociados con los algoritmos considerados estado del arte en la actualidad. Esta tesis trata sobre el entrenamiento de algoritmos de aprendizaje automático que ayuden al personal clínico en la interpretación automática de ECG e iECG. Esta tesis tiene cuatro contribuciones principales. En primer lugar, se ha desarrollado una herramienta de delineación del ECG para la predicción de los inicios y finales de las principales ondas cardíacas (ondas P, QRS y T) en registros compuestos de cualquier configuración de derivaciones. En segundo lugar, se ha desarrollado un algoritmo de generación de datos sintéticos que es capaz de paliar el impacto del reducido tamaño de las bases de datos existentes para el desarrollo de algoritmos de delineación. En tercer lugar, la metodología de análisis de datos de ECG se aplicó a datos similares, en registros electrocardiográficos intracavitarios, con el mismo objetivo de marcar inicios y finales de activaciones locales y de campo lejano para facilitar la localización de sitios de ablación adecuados en procedimientos de ARF. Para este propósito, el algoritmo de delineación del ECG de superficie desarrollado previamente fue empleado para preprocesar los datos y marcar la detección del complejo QRS. En cuarto y último lugar, el algoritmo de delineación de ECG de superficie fue empleado, junto con un algoritmo de reducción de dimensionalidad, Multiple Kernel Learning, para agregar la información del ECG de 12 derivaciones y lograr la identificación de marcadores que permitan la estratificación del riesgo de muerte súbita cardíaca en pacientes con cardiomiopatía hipertrófica.
Electrocardiographic signals, either acquired on the patient’s skin (surface electrocardiogam, ECG) or invasively through catheterization (intracavitary electrocardiogram, iECG) offer a rich insight into the patient’s cardiac condition and function given their ability to represent the electrical activity of the heart. However, the interpretation of ECG and iECG signals is a complex task that requires years of experience, difficulting the correct diagnosis for non-specialists, during stress-related situations such as in the intensive care unit, or in radiofrequency ablation (RFA) procedures where the physician has to interpret hundreds or thousands of individual signals. From the computational point of view, the development of high-performing pipelines from data analysis suffer from lack of large-scale annotated databases and from the “black-box” nature of state-of-the-art analysis approaches. This thesis attempts at developing machine learning-based algorithms that aid physicians in the task of automatic ECG and iECG interpretation. The contributions of this thesis are fourfold. Firstly, an ECG delineation tool has been developed for the markup of the onsets and offsets of the main cardiac waves (P, QRS and T waves) in recordings comprising any configuration of leads. Secondly, a novel synthetic data augmentation algorithm has been developed for palliating the impact of small-scale datasets in the development of robust delineation algorithms. Thirdly, this methodology was applied to similar data, intracavitary electrocardiographic recordings, with the objective of marking the onsets and offsets of events for facilitating the localization of suitable ablation sites. For this purpose, the ECG delineation algorithm previously developed was employed to pre-process the data and mark the QRS detection fiducials. Finally, the ECG delineation approach was employed alongside a dimensionality reduction algorithm, Multiple Kernel Learning, for aggregating the information of 12-lead ECGs with the objective of developing a pipeline for risk stratification of sudden cardiac death in patients with hypertrophic cardiomyopathy.

Abstract:
Intracavitary ultrasound hyperthermia applicators have the potential to better heat certain tumor sites, especially in the pelvic region, than external techniques. To allow deep, controlled heating, an intracavitary phased array has been developed. The hardware required to drive the array was also developed; including amplifiers, phase shifters, power meters and matching circuits. The entire system is computer controlled and capable of driving up to 64 individual ultrasound transducers. This system was used to conduct acoustic field measurements and in vivo perfused kidney experiments with the phased arrays. These results show that these arrays focus as predicted, and are capable of controlling the heating field by electrically controlling the position of the focus.

Abstract:
Echocardiography is a key diagnostic method in the management of patients with cardiomyopathies.The main echocardiographic findings of hypertrophic cardiomyopathy are asymmetric hypertrophy of the septum, increased echogenicity of the myocardium, systolic anterior motion, turbulent left ventricular (LV) outflow tract blood flow, intracavitary gradient of dynamic nature, mid-systolic closure of the aortic valve and mitral regurgitation. The degree of hypertrophy and the magnitude of the obstruction have prognostic meaning. Echocardiography plays a fundamental role not only in diagnostic process, but also in management of patients, prognostic stratification, and evaluation of therapeutic intervention effects.In idiopathic dilated cardiomyopathy, echocardiography reveals dilation and impaired contraction of the LV or both ventricles. The biplane Simpson’s method incorporates much of the shape of the LV in calculation of volume; currently, three-dimensional echocardiography accurately evaluates LV volumes. Deformation parameters might be used for detection of early ventricular involvement. Stress echocardiography using dobutamine or dipyridamole may contribute to risk stratification, evaluating contractile reserve and left anterior descending flow reserve. LV dyssynchrony assessment is challenging and in patients with biventricular pacing already applied, optimization of atrio-interventricular delays should be done. Specific characteristics of right ventricular dysplasia and isolated LV non-compaction can be recognized, resulting in an increasing frequency of their prevalence. Rare forms of cardiomyopathy related with neuromuscular disorders can be studied at an earlier stage of ventricular involvement.Restrictive and infiltrative cardiomyopathies are characterized by an increase in ventricular stiffness with ensuing diastolic dysfunction and heart failure. A variety of entities may produce this pathological disturbance with amyloidosis being the most prevalent. Storage diseases (Fabry, Gaucher, Hurler) are currently treatable and early detection of ventricular involvement is of paramount importance for successful treatment. Traditional differentiation between constrictive pericarditis (surgically manageable) and the rare cases of restrictive cardiomyopathy should be properly performed.
