Full textThe ovarian carcinoma is a cancer of very poor prognosis, as diagnosis occurs at an advanced stage. A better understanding of the natural history of this cancer is critical interest in order to discover new targeted therapies and to determine new markers for prognosis prediction and therapeutic follow-up. We have chosen to study the tumour stroma which plays probably a crucial role in the tumorigenesis and drug resistance of ovarian carcinomas. This study highlighted that the amount of blood vessels, mast cells and stroma can be used as prognosis indicators. Then, we have focused our study on peritoneal metastasis which are responsible of the recurrence of this disease. We have also finalized an in vivo mice model of peritoneal carcinosis to investigate the different steps of stroma development. Finally, we have tested on this model the effect of an anti-angiogenic drug associated or not with classical chemotherapy

Full textEGFR inhibition shows synergy with radiation in head and neck carcinomas. Aim 1 was to test the benefit of adding gefitinib to postoperative irradiation with cisplatin in patients with poor histoclinical factors. Aim 2 was to identify predictive biomarkers (EGFR pathways + crosstalks, angiogenesis, tumor-stroma interactions, apoptosis, cell cycle, numan papilloma virus) of outcome to gefitinib. Aim 3 was to compare EGFR protein expression measurement methods (binding assay on membranes, Western blotting (WB) on membranes and total homogenates, and immunohistochemistry (IHC) on tissue microarrays. Distributions and ranges of EGFR expression were method-dependent. Moderate correlations occurred between EGFR expression by binding and WB or IHC. Phosphorylated EGFR levels correlated with total EGFR by WB or ligand binding, but not by IHC. Highest correlation occurred between EGFR and pEGFR levels by WB on membranes. PEGFR/EGFR by WB on membranes declined with increasing EGFR. The gefitinib – chemoradiation combination did not decrease standard treatment dose intensity, but did not benefit the overall population. Insulin-like growth factor 1 receptor (IGF-1R) was a prognostic and predictive biomarker of outcomes to gefitinib. High expression of p21-protein kinase 1 (PAK1), involved in cell motility, by WB, CD31, a biomarker of angiogenesis, and IGF-1R, by IHC, was associated with worse outcomes. An interaction was observed between IGF-1R and Gefitinib, patients with high IGF-1R benefited from gefitinib while those with low IGF-1R fared worse. EGFR tyrosine kinase inhibitors may not afford clinical benefit in unselected populations of head and neck cancer patients. These points to the potential advantage of adaptive clinical design and personalizing treatment for gefitinib based on IGF-1R expression. Confirmatory retrospective studies will be necessary in independent population treated with EGFR Inhibitors

Full textEmerging high-throughput screening technologies are rapidly providing opportunities to identify new biologically and clinically relevant tumor entities previously indistinguishable. They contribute also to the identification of new diagnostic and prognostic biomarkers as well as lists of new potential therapeutic targets. It is in this context that this work is born, at the border between conventional classification and molecular classification. Firstly, we have preformed a series of studies to identify new prognostic markers. We have established a set of 21 proteins whose combined expression distinguished between tumors associated with different long term metastasis-free survival. Then, we have confirmed the concept of molecular taxonomy at the protein level by the identification of molecular subtypes of breast cancer. Lastly, we have started the individual analysis of these subtypes in order to diagnose and to understand the biological mechanisms to witch they are subjected

Full textToday Immunotherapy is clearly an alternative choice in the treatment of cancers. Its main objective is to enhance the cytotoxic immune response against tumor cells while preserving normal cells. We have previously demonstrated that there is an antitumor immune response in the Non-Small-Cell lung carcinoma (NSCLC) and cytotoxic T lymphocytes (CTL) contribute to NSCLC tumor regression. We further showed that the CD103 integrin interaction (oftenly expressed on tumor infiltrating lymphocytes (TIL)) with its ligand, the epithelial cell marker E-Cadherin, expressed at the surface of tumor cells, is necessary for the polarization and exocytosis of TIL cytotoxic granules and to trigger the lysis of the tumor target cells. The main purpose of my thesis project is to determine the actual role/ contribution of CD8+/CD103+ T lymphocytes (infiltrating the epithelial tumors) in the regulation of antitumor CTL response and to study the role of CD103 in the regulation of their in situ effector functions. Firstly, TIL infiltrating human NSCLC were characterized at transcriptional and phenotypic level. My results show that CD8+/CD103+ T lymphocytes have a molecular signature characteristic of memory T cells resident in tissues (MRT), with expression of CD69 receptors and CD45RO. My results also showed that this cell population co-Expresses the inhibitory receptors, PD-1 and Tim-3.In a second step, I studied the functionality of CD8+/CD103+ TIL and the role of CD103 in the regulation of anti-Tumor cytotoxic activity. My results have first indicated that CD103+ TIL are more sensitive to activation induced cell death (AICD) than TIL-CD103- and CD103+ TIL express granzyme B and CD107a after specific activation. Furthermore, CD103+ TIL are able to exert a specific cytotoxic activity against autologous tumor cells following the neutralization of PD-1- PD-L1 interaction, and that of anti-CD103 antibody inhibits this blocking function. After, I analyzed the impact of the expression of CD103 on the surface of TIL on the survival of patients with NSCLC stage 1. My results revealed that this integrin promotes the infiltration of TIL in epithelial tumor regions and a strong expression of CD103 on TIL correlates with improved patient survival. Finally, I examined the role of CD103 in this function and the antitumor immune response in vivo. My preliminary results showed a tumor growth delay of LL2 tumors transfected with E-Cadherin and CCL5 grafted in CD103-WT mice. Furthermore inhibition of growth correlates with a higher tumor infiltrating with CD8+/CD103+ T lymphocytes. These results suggest an important role of the coexpression of CCL5 and E-Cadherin by the tumor in the recruitment and retention of CTL at the tumor site. The whole work supports the role of CD103 in regulating the CD8 T cells-Mediated immune response in epithelial tumors and the usefulness of anti-PD-1 neutralizing and anti-Tim-3 for reversing the depletion of this lymphocyte population CD8+ / CD103+

Full textHigh Troughput technologies dissect several aspects of cancer. Transcriptomic analyses have defined five breast cancer molecular subtypes. During my phD I analysed two molecular subtypes associated with agressive phénotype and bad prognosis : ERBB2 and Luminal B subtypes. Firstly, I caracterized genomic heterogenity of ERBB2 amplified tumors which is related to estrogen receptor (ER) expression. Integrated genomictranscriptomic analyses identified PVT1 and TRSP1 as candidate oncogenes in ER positive ERBB2 amplified tumors. On the contrary, RE négative tumors express Wnt/ß-catenin related genes, an other interesting therapeutic strategy. Secondly, genomic analyses of Luminal B tumors point 8p12 amplification as the major genomic évents. This amplification target several known putative oncogenes (RCP, ZNF703, PPAPDC1B…). ZNF703 overexpression induced cancer stem cells increase in MCF7 cell line. ZNF703 co-localise with SMRT and PHB-2 in the nucleus. Finally, ZNF703 overexpression reduce RE transcriptionnal activity. These results are concordant with others showing that ZNF703 as un HDAC dependant transcriptionnal répression activity. Thus, HDAC inhibitors could be a interesting therapeutic strategy for luminal B tumors. Together, these studies show importance of combination of several aspect to define potential therapeutic strategy associated with breast cancer molecular subtypes

Full textWorldwide each year, more than 150 000 women die from epithelial ovarian cancer largely due to emergence of resistance to chemotherapy. Approximately half of these cancers display molecular alterations that cause deficiency of DNA repair via homologous recombination (HRD), which confer sensitivity to PARP protein inhibitors (PARPi). To date, there is no test capable of fully identifying the HRD phenotype, thus limiting access to these treatments. In this context, we are developing functional assays based on the use of tumor explant slices and then, on the use of tumor organoids derived from ovarian tumors of chemotherapy-naive or previously treated patients. The culture of explants was unsuitable for this application and we then focused our work on tumor organoids. Tumor organoids were exposed to carboplatin (first-line treatment) and two PARP inhibitors (olaparib and niraparib) used for maintenance therapy. In parallel, we collected clinical data from patients (survival, platinum-free interval, RECIST, treatments) to evaluate the predictive potential of these models. The established tumor organoids responded heterogeneously to different drugs, and our results show that the organoid-based assay is capable of identifying patients highly resistant to carboplatin, suggesting that this functional assay could have a predictive value for patients treated with carboplatin. Regarding the potential of organoids in predicting PARPi response, multiple sensitivity profiles have been identified, but the correlation with clinical response has yet to be determined by studies conducted on tumor samples from patients treated with these drugs

Full textThe increased incidence and the lack of therapeutic resources for non-operable forms of HPV+ cancer patients constitutes a major challenge. High immunosurveillance in HPV-associated tumors and the presence of viral antigens associated with oncogenesis of these cancers should focus on the development of immunotherapy strategies such as anti-tumor vaccination and adoptive transfer of TILs. These technological advances encourage a better understanding of immune responses in these pathologies and aim to develop strategies combining immunotherapies for the treatment of all HPV-related cancers. We first looked for tumor antigens associated with the prognosis of patients with anal canal cancer. The patients were treated with a combination of chemotherapy whose therapeutic benefit was demonstrated by our team. Monitoring specific T-immune responses in the peripheral blood of these patients has shown that telomerase is a tumor antigen associated with SCCA; and moreover that the presence of Telomerase-specific LT Th1 is a predictor of progression-free survival at 12 months. Our data also highlighted the influence of M-MDSC on the T-specific immune responses of our antigens as well as on the survival of patients with SCCA. As a result, M-MDSCs are a prognostic factor in the response to treatment of patients with metastatic SCCA treated with chemotherapy. The second work of this thesis validated the feasibility of isolating TILs from biopsy samples from patients with HPV-associated cancer. The specific T immune responses of HPV16 oncoproteins are correlated in 50 and 60% of cases between peripheral blood and tumor. The final objective of this thesis work demonstrated the immunogenicity of the SALL4 protein, a transcription factor associated with pluripotency and self-renewal of embryonic stem cells. We have generated anti-SALL4 CD4 Th1 response analysis technology to monitor immune responses in patients with digestive adenocarcinoma. Our work has also shown a low frequency of SALL4-specific T responses in the peripheral blood of patients with SCCA. These results suggest that the presence of specific SALL4 responses in the peripheral blood of SCCA patients could be subject to immunomonitoring resulting in a decrease in the frequency of CD4 LT SALL4+. It would be interesting to analyze the presence of specific LT of this antigen in the early forms of HPV-related cancers

Full textBladder cancer is the sixth cause of cancer mortality in France and its incidence is increasing since the last 20 years, with no improvement in survival outcomes. Bladder carcinogenesis involves different molecular mechanisms such as in many cancers. The recent development of new targeted therapies targeting signaling pathways provides new therapeutic hopes.In this work, we choose to study three molecular pathways in order to identify new prognostic markers and new therapeutic targets in urothelial carcinoma: angiogenesis, Hedgehog signaling pathway, and microRNAs. Real-time quantitative RT-PCR was performed to measure simultaneously expression levels of several genes with precise and reproductible RNA quantification. Our results were correlated with clinical outcomes to identify new molecular markers associated with bladder cancer evolution and to guide the potential use of targeted therapies.We were able to demonstrate that expression levels of several transcripts differ significantly in bladder tumors as compared to normal bladder and that some of them may have a prognostic implication. This is the case of VEGF, which appears to be an interesting molecular marker since there are targeted therapies specifically targeting the pathway and several ongoing trials in bladder cancer. The Hedgehog pathway also appears to be altered in bladder tumors, with a ligand-dependent activation. Then, we were able to identify several deregulated microRNAs and describe a molecular 3 miRNA-signature (miR-9, miR-182 and miR-200b) having a prognostic value in muscle-invasive bladder tumors. All these studies confirm the major interest of molecular biology and new targeted therapies in the treatment of bladder cancer, with the hope of improving management and evolution

Full textThe aim of this thesis was to study the distribution, determinants and consequences of time to diagnosis of cancer in children, through a systematic review of the literature and an analysis of lawsuits in France and Canada, and two population-based studies of tumors with particularly long diagnosis delays: medulloblastoma and Ewing sarcoma.The systematic review did not identify any significant decreases in time to diagnosis during the studies. Long times to diagnosis were associated with older age, histological type and location of the tumor. Associations between time to diagnosis and severity of the disease varied. Only a third of the court-appointed experts (n = 56) provided testimony concordant with the available medical literature.The median time to diagnosis of children with medulloblastoma in the area of Paris (n = 166) was 65 days. Diagnosis delays were paradoxically associated with less frequent metastasis and favorable histology, but not with survival, or sequelae.The median time to diagnosis of children with Ewing sarcoma in France (n = 436) was 70 days. Diagnosis delays, related with older age and tumor location, were not associated with tumor size, presence of metastasis, surgical outcome, or survival.For some tumors, an association between time to diagnosis and severity of the disease is well established (e.g. retinoblastoma), or highly probable. For others, the lack of demonstrated associations could tone down the perception of the supposed consequences of diagnosis delays - but does not exempt from trying to reduce them, in order to alleviate their psychological consequences
