A Case of Advanced Hepatocellular Carcinoma with Bone Metastases Managed with Tyrosine Kinase Inhibitors and Aggressive Palliative Radiation Therapy: Role of Combination Therapy for Extending Survival

We report the case of a 68-year-old man with advanced hepatocellular carcinoma (HCC) with multiple bone metastases (BM) treated with tyrosine kinase inhibitors. Despite an insufficient disease control on BM with a progression free survival (PFS) of 6 months, sorafenib was not discontinued and multiple radiation therapy (RT) sessions with a palliative purpose were performed. Thanks to this aggressive radiotherapy approach in order to control the bone tumor burden, the patient has continued sorafenib for 34.6 months achieving an overall survival (OS) of 41.3 months. This result highlights the importance of a tailored management of patients with advanced HCC and the role of the RT for BM control, even if at lower cumulative radiation dose, for extending patient survival

The Perceived Ability of Gastroenterologists, Hepatologists and Surgeons Can Bias Medical Decision Making

: Medical errors are a troubling issue and physicians should be careful to scrutinize their own decisions, remaining open to the possibility that they may be wrong. Even so, doctors may still be overconfident. A survey was here conducted to test how medical experience and self-confidence can affect physicians working in the specific clinical area. Potential participants were contacted through personalized emails and invited to contribute to the survey. The "risk-intelligence" test consists of 50 statements about general knowledge in which participants were asked to indicate how likely they thought that each statement was true or false. The risk-intelligence quotient (RQ), a measure of self-confidence, varies between 0 and 100. The higher the RQ score, the better the confidence in personal knowledge. To allow for a representation of 1000 physicians, the sample size was calculated as 278 respondents. A total of 1334 individual emails were sent to reach 278 respondents. A control group of 198 medical students were also invited, of them, 54 responded to the survey. The mean RQ (SD)of physicians was 61.1 (11.4) and that of students was 52.6 (9.9). Assuming age as indicator of knowledge, it was observed that physicians ≤34 years had a mean RQ of 59.1 (10.1); those of 35-42 years had 61.0 (11.0); in those of 43-51 years increased to 62.9 (12.2); reached a plateau of 63.0 (11.5) between 52-59 years and decreased to 59.6 (12.1) in respondents ≥60 years (r2:0.992). Doctors overestimate smaller probabilities and under-estimate higher probabilities. Specialists in gastroenterology and hepato-biliary diseases suffer from some degree of self-confidence bias, potentially leading to medical errors. Approaches aimed at ameliorating the self-judgment should be promoted more widely in medical education

Noncoding RNAs in Hepatocellular Carcinoma: Potential Applications in Combined Therapeutic Strategies and Promising Candidates of Treatment Response

The incidence of hepatocellular carcinoma (HCC) is increasing, and 40% of patients are diagnosed at advanced stages. Over the past 5 years, the number of clinically available treatments has dramatically increased for HCC, making patient management particularly complex. Immune checkpoint inhibitors (ICIs) have improved the overall survival of patients, showing a durable treatment benefit over time and a different response pattern with respect to tyrosine kinase inhibitors (TKIs). Although there is improved survival in responder cases, a sizeable group of patients are primary progressors or are ineligible for immunotherapy. Indeed, patients with nonviral etiologies, such as nonalcoholic steatohepatitis (NASH), and alterations in specific driver genes might be less responsive to immunotherapy. Therefore, improving the comprehension of mechanisms of drug resistance and identifying biomarkers that are informative of the best treatment approach are required actions to improve patient survival. Abundant evidence indicates that noncoding RNAs (ncRNAs) are pivotal players in cancer. Molecular mechanisms through which ncRNAs exert their effects in cancer progression and drug resistance have been widely investigated. Nevertheless, there are no studies summarizing the synergistic effect between ncRNA-based strategies and TKIs or ICIs in the preclinical setting. This review aims to provide up-to-date information regarding the possible use of ncRNAs as therapeutic targets in association with molecular-targeted agents and immunotherapies and as predictive tools for the selection of optimized treatment options in advanced HCCs

Serum micrornas as novel biomarkers for primary sclerosing cholangitis and cholangiocarcinoma

The diagnosis of primary sclerosing cholangitis (PSC) is difficult due to the lack of sensitive and specific biomarkers, as is the early diagnosis of cholangiocarcinoma (CC), a complication of PSC. The aim of this study was to identify specific serum miRNAs as diagnostic biomarkers for PSC and CC

RANK-RANKL-OPG Axis in MASLD: Current Evidence Linking Bone and Liver Diseases and Future Perspectives

Metabolic dysfunction-associated steatotic liver disease (MASLD)-and its worse form, metabolic-associated steatohepatitis (MASH), characterised by inflammation and liver damage-corresponds to the liver's involvement in metabolic syndrome, which constitutes an economic burden for healthcare systems. However, the biomolecular pathways that contribute to steatotic liver disease are not completely clear. Abnormalities of bone metabolism are frequent in people affected by metabolic liver disease, with reduced bone density and an increased risk of fracture. Receptor activator of NF-kappa B (RANK), receptor activator of NF-kappa B ligand (RANKL), and osteoprotegerin(OPG) are critical regulators of bone metabolism, performing pleiotropic effects, and may have potential involvement in metabolic disorders like MASLD, resulting in a topic of great interest and intrigue. This narrative review aims to investigate this potential role and its implications in MASLD development and progression and in hepatocellular carcinoma, which represents its worst complication

Management of adverse events with tailored sorafenib dosing prolongs survival of hepatocellular carcinoma patients

Sorafenib is associated with multiple adverse events (AEs), potentially causing its permanent interruption. The impact of the physicians experience on the management of these AEs and the relative implications on clinical outcomes are unknown. We verified if the AEs management changed over time and if these modifications impacted on treatment duration and overall survival (OS)
