Full textOvarian cancer (OC) is the deadliest gynecological cancer, causing over 200,000 deaths worldwide every year. Diagnosis of OC is extremely difficult and late diagnosis leads to delays in patient management thus reducing the chances of survival. Against this backdrop, we have developed a real-time diagnostic and prognostic tool: SpiderMass. Initially, to enable early diagnosis and preventive action, we focused on the origin of the most aggressive OC subtype: high-grade serous cancer (HGSOC). Following the discovery of lipid and protein markers specific to pre-neoplastic lesions of the fimbria, we highlighted the underlying mechanisms linked to these lesions and confirmed that they were at the origin of HGSOC. Secondly, we studied all the lipid molecular signatures specific to the different OC subtypes to build a classification model using SpiderMass technology for diagnostic. This model, combining both molecular and patient morphological data, was able to recognize all subtypes in real time ex vivo. We have also developed a new mass spectrometry imaging model enabling direct visualization of different immune cells within tissues. This model provides an accurate diagnosis of the different types of ovarian cancer, and can associate a prognosis with them, given that patient survival is closely linked to the infiltration of immune cells within the tumor. We have demonstrated that this imaging model is applicable to several types of cancer, including ovarian cancer and glioblastoma. Combined with these innovative models, SpiderMass guides the surgeon during the operation to reduce excision margins and provides a reliable diagnosis and prognosis to propose the best treatment to the patient

Full textGBM is the most common (∼45% of all gliomas) and aggressive primary malignant brain tumor in adults. As described in this document's introduction, GBM highly heterogeneous phonotype associated with molecular signatures and gene expressions, but also with hypoxic and inflammatory microenvironmental conditions, contribute to frequent recurrence after complete resection-radio/chemotherapy, and explain the multiple therapeutic failures. Most of the current treatment options for GBM, although sometimes multimodal, the survival of GBM patients is not significantly improved, and the challenges to improve patient survival and quality of life remain enormous. Thus, the identification of differentially expressed factors that could better define the biological behavior of GBM, would provide a basis for the development of novel therapies and may be more effective. One of the characteristics of GBMs is their highly migratory and invasive properties, relayed mainly by chemotactic factors belonging to the hypoxic and inflammatory tumor microenvironment. G-protein coupled receptors (GPCRs) and their ligands, particularly the chemokines GPCRs, overexpressed in GBMs and stimulating migration, invasion and neoangiogenesis, play a key role in the development of GBM and the acquisition of an aggressive phenotype. In this context, our team demonstrated that UT, the receptor of urotensin II (UII), a pro-angiogenic and pro-inflammatory chemokine, as well as the well-known chemokine system SDF-1/CXCR4 are systematically co-expressed in GBMs particularly in vascular and perinecrotic areas and their expression are correlated with grade. We also demonstrated in vitro that UII/UT stimulate GBM cells chemotactic migration and invasion via activation of the pathways Gαi/PI3K and Gα13/Rho/ROCK, pathways that have previously been identified for the SDF-1α/CXCR4 system and other chemotactic GPCRs. In addition, a recent principal component analysis of TCGA (The Cancer Genome Atlas) database performed by Alexandre Mutel, PhD student in the team, has identified the expression signature of GPCRs in gliomas and particularly those which are overexpressed in mesenchymal GBM, among which many chemotactic GPCRs are included. Taking together, their redundant expression and signaling activity frequently associated with tumorigenesis, particularly in GBMs, raises the issue of studying signaling nodes common to all these GPCRs. These nodes, are primarily represented by heterotrimeric G proteins, composed of α, β and γ subunits, that couple these GPCRs relaying many intracellular secondary effectors, probably essentials in the regulation of GBM aggressiveness. In this context, the aim of my thesis work was to identify the main Ga, b and g subunits among the 31 G proteins expressed in human gliomas and those more specifically associated with the malignant grade, and the aggressiveness of GBMs and then to determine the role of one of these specific G proteins in GBM cells proliferation and invasion mechanisms. For that, we first analyzed the expression of the 31 subunits (15α, 5β and 11γ) of G proteins from the TCGA database and showed that the mRNA expression of Gαz, Gαi1, Gβ4, Gβ5 et Gγ3 are relatively low in GBMs while Gα12, Gα13, Gα15, Gαi2, Gαi3, Gβ2, Gγ5, Gγ11 and Gγ12 subunits, are particularly overexpressed in GBM and are associated with a poor prognosis in terms of recurrence and patient survival

Full textGliomas are the main primary brain tumours affecting around 4000 new patients in France each year. Half of gliomas are detected in the advanced stage of glioblastoma (grade IV) while 15% of tumours are diagnosed in stage II (diffuse low-grade gliomas-DLGG). These tumors affect young patients and bear characteristic mutations, including a mutation for the enzyme IDH1 commonly found in secondary glioblastomas. These low-grade tumours are treated by surgery, ideally in awake condition but due to their diffuse nature, the residual part will progress inexorably to stage III or IV with overall survival between 5 and 15 years after diagnosis. Tumor progression is highly variable and unpredictable from one patient to another. Foci of tumor progression have been identified in 20% of patients with DLGG. These foci show a higher cell density and an increased Ki67. My thesis work consisted in studying the cellular and molecular changes associated with tumor progression. From the RNA profile of the foci and adjacent territories, I was able to highlight through high-throughput techniques significant decrease in gene expression in the foci, particularly of AGXT2L1/ETNPPL, carboxypeptidase E, EDNRB, SFRP2. I hypothesized that SFRP2 and ETNPLL could oppose cell proliferation and that their decrease would pave the way for tumor transformation. An inverse correlation between the amount of ETNPPL and the survival of patients with hepatocarcinoma has been published. By limiting the amount of phospholipid precursors in the cell, ETNPPL could act as a brake against proliferation and indeed, its decrease in glioma transformation foci could remove this inhibition. My PhD work will have been innovative in the comparative approach of the different tumors’ compartments for each patient studied and will have revealed ETNPPL as correlated to gliomagenesis and as potential therapeutic target

Full textWe developed a region of interest-based (ROIs) computer-aided diagnosis system (CAD) to characterize International Society of Urological Pathology grade (ISUP) ≥2 prostate cancers at multiparametric MRI (mp-MRI). Image parameters from two multi-vendor datasets of 265 pre-prostatectomy and 112 pre-biopsy MRIs were combined using logistic regression. The best models used the ADC 2nd percentile (ADC2) and normalized wash-in rate (WI) in the peripheral zone (PZ) and the ADC 25th percentile (ADC25) in the transition zone (TZ). They were combined in the CAD system. The CAD was retrospectively assessed on two multi-vendor datasets containing respectively 158 and 105 pre-biopsy MRIs from our institution (internal test dataset) and another institution (external test dataset). Two radiologists independently outlined lesions targeted at biopsy. The Prostate Imaging-Reporting and Data System version 2 (PI-RADSv2) score prospectively assigned at biopsy and the CAD score were compared to biopsy findings. At patient level, the areas under the Receiver Operating Characteristic curve (AUC) of the PI-RADSv2 score were 82% (95% CI: 74-87) and 85% (95% CI: 79-91) in the internal and external test datasets respectively. For both radiologists, the CAD score had similar AUC results in the internal (82%, 95% CI: 76-89, p=1; 84%, 95% CI: 78-91, p=1) and external (82%, 95% CI: 76-89, p=0.82; 86%, 95% CI: 79-93, p=1) test datasets. Combining PI-RADSv2 and CAD findings could have avoided 41-52% of biopsies while missing 6-10% of ISUP≥2 cancers. The CAD system confirmed its robustness showing good discrimination of ISUP ≥2 cancers in a multicentric study involving 22 different scanners with highly heterogeneous image protocols. In per patient analysis, the CAD and the PI-RADSv2 had similar AUC values (76%, 95% CI: 70-82 vs 79%, 95% CI: 73-86; p=0.34) and sensitivities (86%, 95% CI: 76-96 vs 89%, 95% CI: 79-98 for PI-RADSv2 ≥4). The specificity of the CAD (62%, 95% CI: 53-70 vs 49%, 95% CI: 39-59 for PI-RADSv2 ≥4) could be used to complement the PI-RADSv2 score and potentially avoid 50% of biopsies, while missing 13% of ISUP ≥2 cancers. These findings were very similar to those reported in the single center test cohorts. Given its robustness, the CAD could then be exploited in more specific applications. The CAD first provided good discrimination of ISUP ≥2 cancers in patients under Active Surveillance. Its AUC (80%, 95% CI: 74-86) was similar to that of the PI-RADS score prospectively assigned by specialized uro-radiologists at the time of biopsy (81%, 95% CI: 74-87; p=0.96). After dichotomization, the CAD was more specific than the PI-RADS ≥3 (p<0.001) and the PI-RADS ≥4 scores (p<0.001). It could offer a solution to select patients who could safely avoid confirmatory or follow-up biopsy during Active Surveillance (25%), while missing 5% of ISUP≥2 cancers. Finally, the CAD was tested with the pre-prostatectomy mp-MRIs of 56 Japanese patients, from a population which is geographically distant from its training population and which is of interest because of its low prostate cancer incidence and mortality. The CAD obtained an AUC similar to the PI-RADSv2 score assigned by an experience radiologist in the PZ (80%, 95% CI: 71-90 vs 80%, 95% CI: 71-89; p=0.886) and in the TZ (79%, 95% CI: 66-90 vs 93%, 95%CI: 82-96; p=0.051). These promising and robust results across heterogeneous datasets suggest that the CAD could be used in clinical routine as a second opinion reader to help select the patients who could safely avoid biopsy. This CAD may assist less experience readers in the characterization of prostate lesions

Full textHuman ovarian cancer (OvCa) is the deadliest gynecologic malignancy and existing surgical/chemotherapeutic treatment options have been relatively static for decades. We propose that understanding OvCa cell fate decisions taken in response to chemotherapy could guide new therapeutic opportunities. Damage-induced cellular senescence is often associated with TP53 activity, which is heavily mutated in high grade serous (HGS) OvCa (>90%), the most common form of this disease. Here, using patient derived tissues, we show that primary HGS-OvCa cultures predominantly trigger CDKN2A- associated (p16INK4A isoform) senescence following exposure to stress or chemotherapy. Key senescence hallmarks including altered morphology, senescence-associated-Betagalactosidase, DNA damage, cell cycle arrest and the senescence-associated secretory phenotype were evaluated and detected in damaged cells. Using tissue microarrays built from pre- and post-treatment human HGS-OvC tissue samples with accompanying clinical data, we quantified post-treatment hallmarks of senescence including reduced cell proliferation weeks after chemotherapy. Importantly, p16INK4A expression in pretreatment HGS-OvC samples correlated with increased patients survival, suggesting for the first time that senescence-competence in human cancer cells may have a beneficial impact on treatment outcomes for patients. In order to guide the potential improvement of existing human therapies via pharmacological senescence manipulation, our results suggests that it is important to determine for many types of human cancer whether treatment-induced senescence positively or negatively impacts disease progression and patient survival.
