Analysis of Immune and Inflammatory Microenvironment Characteristics of Noncancer End-Stage Liver Disease.

Chronic liver injury eventually progresses to cirrhosis and end-stage liver disease (ESLD), which are the leading causes of death in patients with liver disease worldwide. ESLD has a variety of etiologies and a complex pathogenesis. This study analyzed the characteristics of ESLD by studying the immune microenvironment and inflammatory microenvironment of ESLD caused by 4 noncancer diseases, including HBV-ALF, ALF, AILD, and AH. We collected transcriptome data from noncancer ESLD patients, collected liver tissue samples and blood samples from ESLD liver transplant patients, and analyzed the immune and inflammatory microenvironments in the liver and blood. The results showed that with the exception of HBV-induced ESLD, there were no significant differences in immune microenvironment scores among patients with ESLD caused by other noncancer diseases. Moreover, there were no significant differences in the inflammatory microenvironment in the liver and blood of patients with ESLD caused by the 4 noncancer diseases. Furthermore, we found that the cytokine, IL-15, could predict the prognosis of ESLD patients.

Recent advances in recurrent hepatocellular carcinoma therapy.

Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, accounting for 75%-85% of cases. Although treatments are given to cure early-stage HCC, up to 50%-70% of individuals may experience a relapse of the illness in the liver after 5 years. Research on the fundamental treatment modalities for recurrent HCC is moving significantly further. The precise selection of individuals for therapy strategies with established survival advantages is crucial to ensuring better outcomes. These strategies aim to minimize substantial morbidity, support good life quality, and enhance survival for patients with recurrent HCC. For individuals with recurring HCC after curative treatment, no approved therapeutic regimen is currently available. A recent study presented novel approaches, like immunotherapy and antiviral medication, to improve the prognosis of patients with recurring HCC with the apparent lack of data to guide the clinical treatment. The data supporting several neoadjuvant and adjuvant therapies for patients with recurring HCC are outlined in this review. We also discuss the potential for future clinical and translational investigations.

Progress and prospects of biomarkers in primary liver cancer (Review).

Tumor biomarkers are important in the early screening, diagnosis, therapeutic evaluation, recurrence and prognosis prediction of tumors. Primary liver cancer is one of the most common malignant tumors; it has high incidence and mortality rates and seriously endangers human health. The main pathological types of primary liver cancer include hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined HCC­cholangiocarcinoma (cHCC­CC). In the present review, a systematic outline of the current biomarkers of primary liver cancer is presented, from conventional blood biomarkers, histochemical biomarkers and potential biomarkers to resistance­associated biomarkers. The important relationships are deeply elucidated between biomarkers and diagnosis, prognosis, clinicopathological features and resistance, as well as their clinical significance, in patients with the three main types of primary liver cancer. Moreover, a summary of several important biomarker signaling pathways is provided, which is helpful for studying the biological mechanism of liver cancer. The purpose of this review is to provide help for clinical or medical researchers in the early diagnosis, differential diagnosis, prognosis and treatment of HCC.
