Повний текст джерелаHead and Neck Squamous Cell Carcinomas (HNSCC) were the seventh most frequent tumors worldwide in 2020. Although therapeutic perspectives have evolved favorably over the last ten years, the search for useful biomarkers for therapeutic stratification remains a major challenge for these tumors. In addition, the induction of antitumor adaptive immunity seems to be an increasingly important mechanism for the efficacy of approved therapies in HNSCC. In this perspective, the study of the interactions between tumor cells and immune cells of the tumor microenvironment (TM) is essential. Several anticancer therapies have been reported for the induction of tumor cell death by ferroptosis, an iron-dependent regulated necrosis that occurs during unresolved oxidative stress in the cell. In the first part of our work we focused on the possibility of exploiting ferroptosis in Human Papillomavirus positive HNSCC (HPV+ve HNSCC), which usually show higher oxidative stress than HPV negative HNSCC (HPV-ve HNSCC). Using in silico analyses, we observed low expression of SLC7A11, an essential transporter in the cell for the synthesis of glutathione, an inhibitor of oxidative stress, in HPV+ve HNSCC compared to HPV-ve HNSCC. In vitro, HNSCC cell lines expressing HPV E6/E7 transforming proteins showed higher sensitivity to erastin-induced ferroptosis compared to their parental cell lines. In the second part of our work, we studied the regulation of PD-L1 (Programmed Death-Ligand 1) expression by different approved therapies in HNSCC. The expression of PD-L1 by tumor and inflammatory cells of the TM is indeed partly responsible for the frequent inactivation of cytotoxic T cells of the TM, and thus represents an obstacle for the induction of antitumor adaptive immunity. We observed a specific regulation of PD-L1 by 5-fluorouracil (5-FU) that was dependent on the DNA damage response and the JAK / STAT pathway

Повний текст джерелаCetuximab (CTX) is an anti-EGFR monoclonal antibody approved in head and neck cancer, which prescription modalities may be improved. After induction chemotherapy (Tremplin study), compared to cisplatin, CTX was less toxic but did not improve larynx preservation. During first infusion, CTX can induce an anaphylaxis reaction due to the presence of preexisting anti-αGal IgE. Predictive assays detecting these IgE were developed and tested in 41 patients, with sensitivity and negative predictive values of 100%. Relationship between serum concentrations and efficacy/toxicity was studied in 34 patients. CTX pharmacokinetics was described using a model combining non-saturable (CL) and saturable (k0) eliminations. Global clearance, which reflects patient exposure, was related to progression free and overall (OS) survivals. Severe radiation dermatitis was also associated with OS. A pharmacokinetic simulation suggests that, in comparison to standard CTX infusion, an infusion every three weeks will lead to similar AUC but to different residual concentrations

Повний текст джерелаThe objective of the thesis was to decipher the molecular state of tumor infiltrating dendritic cell (DC) and their relation to the tumor microenvironment. By combining the analysis of human tumor samples by flow cytometry and RNA sequencing, of tumor secretome and of a large dataset of in vitro DC-Tcell interactions I obtained 2 main findings. First, we reported a novel classification of human activated DC, that are either “secretory” that is specialized in secreting cytokines and chemokines, or “helper” that is specialized at inducing the secretion of a broad range of T helper cytokines after cell co-culture. DC infiltrating inflamed human head and neck cancer matched the “secretory” phenotypic and transcriptomic signatures. Beyond this novel biological concept, this classification is of importance as a theoretical basis for adjuvant-based immunotherapy. Secondly, we showed that tumor inflammation was not the main prognostic factor for oral cavity cancer (OCC) patients, but that MMP2 and the presence of extra-nodal extension were independent predictors of reduced disease-specific survival. We could stratify OCC into 4 prognostic groups and showed that they had similar expected rates of response to immunotherapy. Our data may serve to design a biomarker-driven clinical trial proposing neoadjuvant chemotherapy or immunotherapy to high-risk patients, with the goal of reducing the percentage of OCC patients that will present with early and severe recurrences

Повний текст джерелаHead and neck squamous cell carcinomas (HNSCC) have a poor prognosis, due to their resistance to standard treatments. In most cases, locoregional recurrence or metastases occur. This study has focused on the role of cancer stem cells (CSC) in the radioresistance of the SQ20B HNSCC cell line and their therapeutic targeting in association with photon or carbon ions irradiation. A subpopulation of SQ20B-CSC has been isolated by cell sorting based on 3 specific characteristics of HNSCC-CSC : Hoechst 33342 exclusion, CD44 expression and high aldehyde dehydrogenase activity (ALDH). SQ20B/SP/CD44high/ALDHhigh cells show the CSC characteristics (in vitro and in vivo tumorigenesis, high radioresistance). The response of CSC to both types of irradiation was compared to the non-“stem cells” SQ20B/SP/CD44low sub-population. The observed radioresistance involves a decrease in apoptotic cell death, an increase in proliferative capacities and an overexpression of the Bmi1 self-renewing signaling pathway. The radiosensitizing effects of 3 molecules targeting the CSC has been demonstrated : an induction of apoptotic cell death by the inhibition of the G2/M phase arrest after a treatment with UCN01 ; an inhibition of proliferative capacities using the all-trans-retinoic acid (ATRA) which induce their differentiation ; and an inhibition of Bmi1 by artesunate. These treatments, alone or in combination (UCN01+ATRA) have a synergistic effect with photon or carbon ion irradiation to overcome CSC radioresistance. Preclinical and clinical studies should confirm the benefit of targeting CSC and improve the control of tumor escape in patients with radioresistant HNSCC cancers

Повний текст джерелаB-vitamins and factors related to one-carbon metabolism (OCM) pathway help to maintain DNA synthesis and regulate gene expression and may affect cancer risk. The overarching aim of this thesis is to investigate the importance of OCM biomarkers in the etiology of three distinct cancer sites that differed in their strength of association with smoking. Papers included in this thesis were conducted within two prospective studies, the European Prospective Investigation into nutrition and Cancer (EPIC) study and the Lung Cancer Cohort Consortium (LC3). In paper 1, we investigated if OCM biomarkers are associated with incidence and survival of cancer of the head and neck and esophagus in the EPIC study. We observed that subjects with higher concentrations of homocysteine had increased risk of developing head and neck cancer. In paper 2, we investigated if OCM biomarkers are associated with incidence and survival of renal cell carcinoma (RCC) in the EPIC study. We observed that study subjects with elevated vitamin B6 concentrations had lower risk of RCC in a dose-response fashion and improved survival following diagnosis. In paper 3, we investigated whether OCM factors are associated with lung cancer risk in the LC3 study. Overall, we observed a weak inverse association, with no clear trend, between concentrations of vitamin B6 and folate and risk of lung cancer. The most important conclusion is that elevated vitamin B6 concentrations are associated with lower risk of developing RCC, and also better prognosis among RCC cases. Further studies are warranted to evaluate if vitamin B6 exerts a causal influence on RCC etiology and mortality, or if other metabolic factors are involved

Повний текст джерелаResistance to epidermal growth factor receptor (EGFR) targeted therapy triggered by the tumor niche in head and neck squamous cell carcinoma (HNSCC) represents a challenge in research and in clinics. Despite the fact that over 15% of HNSCC overexpress EGFR, HNSCC are refractory to EGFR Tyrosine Kinase Inhibitors (TKIs) targeted therapy and yet the molecular and cellular mechanisms of EGFR-TKIs resistance in HNSCC are unknown. The tumor niche plays an important role in conventional chemotherapeutic resistance. Cancer associated fibroblasts (CAFs), the most prominent stromal cell in tumor niche, participate in this process. Notably, CAFs are responsible for tumor tissue fibrosis an excessive extracellular matrix (ECM) remodeling that increases matrix stiffness. In carcinoma cells, adhesion to stiff substrate triggers mechano-dependent intracellular signaling pathways that favor tumor resistance to conventional chemotherapies. My work demonstrates that ECM stiffening is responsible for a significant increase of squamous cell carcinoma (SCC) survival upon the treatment with EGFR TKIs, conventional chemotherapies and combination of both. Over 60% more cells survive treatment with the gefitinib EGFR TKI compared to cells plated on soft matrix. Same effect was observed on matrix derived from CAFs that is known to be stiffer compared to the one derived from fibroblasts isolated from normal skin. Further analysis revealed an induction of partial epidermal-to-mesenchymal transition (EMT) in cells plated on rigid matrices. EMT is know to play a role in resistance of cancer cells to treatments, and I have demonstrated that downregulation of know transcriptional factors involved in EMT leads to an increase of cell susceptibility to EGFR TKI when plated on stiff matrix. To understand in more detail what drives the resistance of SCC cells when plated on stiff we conduced an RNA sequencing. RNA sequencing of SCC12 cells plated on soft and stiff matrix revealed AXL as main driver of EGFR TKI resistance in HNSCC. I was able to demonstrated that inhibiting AXL in SCC cells, lying on stiff matrices, reverts the EGFR TKI resistance triggered by the tumor niche. Moreover, I show in 3D cell culture the importance of combining AXL and EGFR TKI in treatment of SCCs. Our overall goal was to identify novel therapeutic targets with reduced resistance opportunity. Finally, research presented in this manuscript carries potential in establishing a prediction biomarker to the response of HNSCCs and other cancers to EGFR TKIs

Повний текст джерелаThe goal of tumor surgery is the complete removal of the primary tumor with sufficient safety margins. Obtaining negative margins is essential for complete healing and it also reduces the risk of developing metastases. Currently, tumor limits are established by visual inspection, palpation and extemporaneous histological evaluation. Nevertheless, this has the disadvantage of being time-consuming and sometimes inaccurate. Fluorescence-guided surgery seems to provide answers to this problem of tumor delimitation with the disadvantage of a lack of specificity for the tumor tissue of the most used marker (indocyanine green, ICG). Moreover, different camera systems exist to guide these surgeries and it seems important to explore their capabilities before introducing them in the clinic.The main objective of this project was to optimize tumor labeling in the context of near- infrared fluorescence guided surgery.For this purpose, we coupled ICG with aptamers (E8 and V8) in order to specifically target tumor cells. Two cell lines were studied: FaDu cells from pharyngeal squamous cell carcinomas and U87 cells from human glioblastomas. The FaDu cells were chosen as a positive model because they present the targets of the E8 and V8 aptamers while the U87 cells were the negative model. These 2 cell types have the ability to associate in homogeneous cell clusters thus constituting a very interesting diffusion model. First results suggesting a specific labeling were obtained by microscopy and flow cytometry. In order to increase the amount of ICG bound to aptamers, ICG aggregates were formed and bound to aptamers.Furthermore, we propose a simple, reproducible and innovative model reproducing the microinvasion by tumor cells in the periphery of the primary tumor. It is a model made of spheroids included in a phantom reproducing the optical properties of tissues

Повний текст джерелаSuccessful chemotherapeutics can induce a type of tumour cell death that is immunogenic, implying that patient’s dying cancer cells function as a therapeutic vaccine and elicit an anti-tumour immune response that controls the residual disease. The three main hallmarks of immunogenic cell death (ICD) are the pre-apoptotic exposure of calreticulin (CRT) on the cell surface, the autophagy-dependent secretion of ATP during the blebbing phase of apoptosis and the post-apoptotic release of the chromatin-binding non-histone protein high mobility group B1 (HMGB1). CRT, ATP and HMGB1 interact with CD91, purinergic receptor P2X, ligand-gated ion channel, 7 (P2RX7) and Toll-like receptor 4 (TLR4), respectively, on the surface of dendritic cells (DCs), thus promoting the engulfment of dying cells, the production of IL-1β and the cross-presentation of tumour-associated antigens to T cells, respectively.Our laboratory has demonstrated that adjuvant chemotherapy exhibits a reduced efficacy in breast and colorectal cancer patients bearing single-nucleotide polymorphisms (SNPs) that compromise the function of P2RX7 or TLR4, such as rs3751143 in P2RX7 (Glu496Ala) and rs4986790 in TLR4 (Asp299Gly).Driven by these results, underpinning the intimate relationship between the success of anti-cancer chemotherapy and an operational immune system, we decided to investigate the effect of these SNPs on disease outcome among non-small cell lung carcinoma (NSCLC) and head and neck squamous cell carcinoma (HNSCC) patients. Additionally, we focused our attention on a SNP in autophagy related 16-like 1 (ATG16L1), namely rs2241880 (Thr300Ala), which compromises the activity of one pivotal autophagic gene. In NSCLC patients, loss-of-function ATG16L1, P2RX7 and TLR4 alleles do not affect overall survival, irrespective of the administration and type of chemotherapy. Conversely, HNSCC patients bearing at least one loss-of-function ATG16L1 or TLR4 allele exhibit a reduced disease-free survival when compared to their wild-type counterparts. This is the first report highlighting a putative prognostic biomarker for this malignancy. Furthermore, taking advantage of a high throughput genotyping study, we delineated a SNP-based signature that predicts the response of breast cancer patients to anthracycline- and taxane-based neoadjuvant chemotherapy. Particularly, the combination of two classical clinicophatological parameters (age at diagnosis and estrogen receptor) and genotype at the ECE1 (rs1076669 Thr341Ile) and PZP (rs2277413 Val813Ala) loci allowed us to define three broad categories with a correspondent probability of achieving pathological complete response. The identification of new biomarkers associated with a reduced/absent response to chemotherapy appears critical for selecting appropriate therapeutic alternatives, and avoiding undesired side effects among non-responders
