Despite advances in the treatment of hepatitis B and C, metabolic diseases, and addiction, HCC incidence continues to rise. In France, between 2010 and 2015, the five-year survival rate for liver cancer (90% of which is HCC) was 18% for men and 19% for women. Treatment of HCC is based on the BCLC classification (Barcelona Clinic Liver Cancer), which evaluates both cancer progression and liver function (Child-Pugh classification). Patients at early stages (0 or A) have a survival rate of over 5 years, while those at more advanced stages (C or D) have significantly lower survival rates, highlighting the importance of better early detection tools.\n\nCurrent screening for HCC in cirrhotic patients involves biannual US-scan. However, ultrasound sensitivity for detecting tumors smaller than 2 cm is around 25%. Therefore, developing personalized strategies to predict and detect early-stage HCC is crucial to improving patient outcomes. Various clinical and biological scores have been developed to assess the risk of developing HCC in cirrhotic patients, but these scores remain imperfect. Molecular heterogeneity in HCC, as revealed by transcriptomic studies, could explain the variability in outcomes and treatment responses. This heterogeneity in occurrence, phenotype, and progression of HCC suggests individual singularities that are not yet well understood.\n\nThese individual singularities are likely linked to the autonomic nervous system (ANS), particularly in the central nervous system (CNS), which regulates various physiological processes. The ANS consists of the sympathetic nervous system (SNS), mainly adrenergic, and the parasympathetic nervous system (PNS), mainly cholinergic. These two systems function antagonistically but with different temporal dynamics. A better understanding of the interaction between tumor cells and their environment through the ANS could lead to the identification of new biomarkers to predict HCC development and therapeutic targets.\n\nThe role of the ANS in cancer development has been explored in various cancers, including prostate, stomach, pancreatic, breast, and ovarian cancers, where the ANS regulates inflammation and immune responses. In chronic liver diseases, the liver is innervated by both sympathetic and parasympathetic fibers, and this innervation plays a role in regulating metabolism, liver regeneration, and fibrosis progression. Chronic liver disease etiologies, such as alcohol consumption, metabolic syndrome, and viral hepatitis, disrupt the balance between the SNS and PNS, contributing to liver dysfunction. The severity of liver damage is linked to autonomic dysfunction, and heart rate variability, a marker of PNS activity, is correlated with survival in patients with terminal-stage HCC.\n\nOur recent research has shown that patients with HCC exhibit a reconfiguration of the intrahepatic ANS, with a consistent cholinergic orientation at the neuro-hepatic synapse. Patients with parasympathetic orientation (as compared to sympathetic orientation) have more aggressive tumors, shorter survival, and, from a pharmacological perspective, anticholinergics increase sensitivity to targeted HCC therapies. Tumor cells and cytotoxic lymphocytes are most strongly associated with cholinergic receptor enrichment and depletion, respectively.\n\nIn this context, the PSYLIVER-PILOTE study builds on these findings by investigating the involvement of the ANS in HCC through non-invasive extra-hepatic measures. The SNS and PNS are connected to brain regions involved in cognitive, emotional, and social information processing, such as the anterior cingulate cortex, insula, ventromedial prefrontal cortex, amygdala, and hypothalamus. These brain areas are involved in cognitive control and emotional processing. Additionally, experimental data from polyvagal theory and neurovisceral integration theory highlight the role of the ANS in regulating cognitive, emotional, and social processes, as well as psycho-behavioral traits. For instance, confronting a person with cognitive tasks and emotional or social information alters the balance of sympathetic and parasympathetic activity. Similar changes are observed in psycho-behavioral disorders like depression, emotional dysregulation, stress, and aggression.\n\nThus, the PSYLIVER-PILOTE study aims to identify extra-hepatic markers of ANS activity associated with HCC, analyzing both electrophysiological indices (from the peripheral nervous system) and psycho-behavioral indices (from the central nervous system). This project could open new avenues for early HCC detection and the development of personalized treatments",[27,28,29,30],"Hepato Cellular Carcinoma","Cirrhosis","Autonomic Nervous System","Central Nervous System",[32,33,34,35],"HCC","cirrhosis","ANS","NRS","RECRUITING","2026-04-23",{"date":39,"type":40},"2026-04-29","ACTUAL",{"date":42,"type":40},"2026-04-17",{"date":44,"type":21},"2028-04-17",{"name":46,"class":47},"Hospices Civils de Lyon","OTHER",1,{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":55,"eligibilityCriteria":56,"healthyVolunteers":57,"sex":17,"minAge":18,"maxAge":58,"enrollmentInfo":59,"targetDuration":4,"studyType":22,"phases":61,"briefSummary":62,"conditions":63,"keywords":66,"overallStatus":36,"whyStopped":4,"lastUpdateSubmitDate":70,"lastUpdatePostDateStruct":71,"startDateStruct":73,"completionDateStruct":75,"leadSponsor":77,"locationsCount":48},"100629233","mandibular-stretching-and-4-4-8-breathing-exercises-on-autonomic-nervous-system-activity-100629233","NCT07472010","Mandibular Stretching and 4-4-8 Breathing Exercises on Autonomic Nervous System Activity","Investigation of the Effects of Mandibular Stretching Exercise and 4-4-8 Breathing Exercise on Autonomic Nervous System Activity, Muscle Tone, and Psychological State: A Randomized Controlled Trial","MSE-BR","Inclusion Criteria:\n\n* Inclusion Criteria:\n* Healthy university students\n* Age between 18 and 30 years\n* Voluntary participation in the study\n* Ability to understand and perform mandibular stretching exercise and 4-4-8 breathing exercise\n\nExclusion Criteria:\n\n* History of neurological disorders\n* Musculoskeletal disorders affecting the jaw, neck, or respiratory system\n* Respiratory diseases\n* Use of medications that may affect the autonomic nervous system\n* Inability to perform the exercises required in the study",true,"30 Years",{"count":60,"type":21},52,[24],"Mandibular stretching exercises and breathing techniques may influence autonomic nervous system activity, muscle tone, and psychological state.
