Topic description
Les tumeurs épidermoïdes de la cavité orale (Oral Squamous Cell Carcinoma, OSCC) sont des tumeurs fréquentes de la tête et du cou. Ces tumeurs apparaissent fréquemment dans un contexte d'exposition au tabac et à l'alcool, et ce sont des cancers relativement fréquents dans le Nord-Ouest de la France. Leur traitement repose essentiellement sur la résection chirurgicale, mais les récidives sont fréquentes. Comme toutes les tumeurs humaines, les OSCC établissent localement un état hypercoagulant qui peut favoriser les complications thromboemboliques. Ces complications constituent une source importante de morbidité et de mortalité chez les patients cancéreux. De toutes les tumeurs humaines, les OSCC sont celles qui expriment le plus les gènes à l'origine de cet état hypercoagulant, même s'il existe de très grandes différences entre les tumeurs individuelles. Nos récentes études de système utilisant des données multi-omics permettent une étude puissante du coagulome de ces tumeurs. Elles suggèrent que les caractéristiques du coagulome des OSCC sont liées au risque de récidive post-chirurgicale des OSCC. Nous proposons un sujet de thèse consacré à l'étude du coagulome des OSCC, envisagé dans le contexte chirurgical. Le projet combine : i) une étude bioinformatique de la dynamique du coagulome des OSCC, destinée à mieux préciser les trajectoires coagulomiques des OSCC dans l'espace (transcriptomique spatiale) et le temps, notamment au fil de la progression / des récidives tumorales ; ii) un volet d'étude in vitro, destiné à reconstituer l'interaction entre cellules cancéreuses, plaquettes et facteurs de coagulation, pour réaliser une étude expérimentale des effets procancers de la coagulation. Globalement, l'étude du coagulome tumoral s'inscrit dans la perspective de la personnalisation du traitement chirurgical des OSCC, grâce à son adossement à la biologie tumorale

Oral Squamous Cell Carcinoma (OSCC) is the most frequent type of head & neck cancer. Due to the high exposition of the French population to tobacco and alcohol, OSCC are frequent in Northern and Western France. Surgical resection with curative intent is the cornerstone of their treatment. Unfortunately, postsurgical recurrence is frequent. Like most human tumors, OSCC are known to locally establish a procoagulant state that favors cancer-associated thrombosis (CAT) and thromboembolic complications. These complications represent a major source of cancer-associated mortality and morbidity for cancer patients. Importantly, among all human tumor types, OSCC express the highest levels of a number of key genes that cause this procoagulant state, however with great heterogeneity among individuals. Our recent studies have applied various Omics and systems approaches to address the regulation and function of the tumor coagulome. Importantly, we have recently observed that the tumor coagulome is linked to the risk of postsurgical recurrence of OSCC. We are therefore proposing a PhD projectt centered on the study of the coagulome of OSCC in the surgical context. The project combines two main axes: i) bioinformatic study of the dynamic coagulome, aiming to explore the trajectories of the coagulome of OSCC in space (spatial transcriptomics) and time, especially along tumor progression/recurrence; ii) in vitro study, with the aim of reconstituting the interactions between OSCC cells, blood platelets and coagulation factors, in order to experimentally address the procancer effets of the coagulation cascade. Overall, our study of the tumor coagulome is part of an effort toward the personalization of the surgical management of cancer. By intersecting tumor biology with the outcome of surgery, we aim to improve and personalize the surgical management of OSCC.

Candidate's profile
Le doctorant devra faire preuve de curiosité, d'une bonne maturité scientifique, et posséder des bases en matière d'analyse moléculaires, de biologie cellulaire, voire en bioinformatique (logiciels R et Python). Une motivation pour les études oncologiques, quoique non strictement requise, serait un avantage.
The PhD candidate should demonstrate curiosity, strong scientific maturity, and a solid foundation in molecular analyses, cell biology, and ideally bioinformatics (R and Python software). While not strictly required, an interest in oncology research would be an advantage.
