Article Abstract

Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer. According to the American Cancer Society, among patients diagnosed with advanced liver cancer, HCC has the sixth-highest incident rate, resulting in a poor prognosis. Surgery, radiofrequency ablation, transcatheter arterial chemoembolization, radiation, chemotherapy, targeted therapy and immunotherapy are the current treatment options available. Immunotherapy, which has emerged as an innovative treatment strategy over the past decade, is serving a vital role in the treatment of advanced liver cancer. Since only a small number of individuals can benefit from immunotherapy, biomarkers are required to help clinicians identify the target populations for this precision medicine. These biomarkers, such as PD-1/PD-L1, tumor mutational burden and circulating tumor DNA, can be used to investigate interactions between immune checkpoint inhibitors and tumors. The present review summarizes information on the currently available biomarkers used for immunotherapy and the challenges that are present.

Background: Alcohol consumption is a risk factor for certain cancers and is increasing in the United States. We estimated the impact of alcohol consumption on cancer incidence trends in the United States from 2008-2019 across six alcohol-related cancers among men and women.

Methods: Average daily alcohol consumption (ADC) was calculated from the National Health Interview Survey (NHIS, 1998-2009) and adjusted to per capita sales data to account for underreporting alcohol use.

Acute or chronic liver damage can result in Hepatic Encephalopathy (HE), a potentially fatal neuropsychiatric condition that leads to cerebral and neurological alterations. Dapagliflozin (DAPA), an orally active Sodium/Glucose cotransporter 2 inhibitor with long duration of action. The study aim was to evaluate the potential protective impact of DAPA against HE caused by Thioacetamide (TAA) in rats.

Background: The suppressor of tumorigenesis 2 (ST2) has emerged as one of the most promising biomarkers for predicting mortality of acute graft-versus-host disease (aGvHD) when measured at the onset of symptoms, but detailed time course studies are needed to understand the potential of ST2 as a risk marker of both aGvHD and chronic graft-versus-host disease (cGvHD), potentially allowing pre-emptive adjustment of immunosuppressive treatment.

Procedure: We measured ST2 levels in 117 children undergoing standard hematopoietic stem cell transplantation (HSCT) before conditioning and at regular intervals post-HSCT.

Results: ST2 levels were significantly increased from Day +7 in patients developing aGvHD of any grade (no GvHD: 23.

Background: The Middle East and North Africa (MENA) region is undergoing demographic shifts potentially increasing metabolic dysfunction-associated steatotic liver disease (MASLD) and its complications. We assessed MASLD prevalence and liver disease burden from 2010 to 2021.

Methods: Data from Global Burden of Disease (GBD), United Nations Population Division and NCD Risk Factor Collaboration covering 21 MENA countries were used for annual percent change (APC) trends per Joinpoint regression.

Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths, primarily due to late-stage diagnosis. In this multicenter study, our goal is to identify functional biomarkers that stratify the risk of HCC in patients with cirrhosis (CP) for early diagnosis.

Methods: Five thousand and eight serum proteins (Somascan) were analysed in Cohort A (477 CP, including 125 HCC).
