Article Synopsis
  • The study investigates the genetic links between vitamin D transporter protein and cytochrome P450-24A1 in cirrhosis patients, both with and without hepatocellular carcinoma (HCC), analyzing their demographic, clinical, and biochemical profiles.
  • A total of 383 individuals were categorized into three groups: patients with cirrhosis and HCC, patients with isolated cirrhosis, and a control group without liver disease, using genetic analysis methods like real-time PCR.
  • Results indicated that specific genetic polymorphisms were more common in patients with HCC, highlighting factors such as advanced age, smoking, and diabetes as predictors for cirrhosis and HCC, while some genetic markers correlated with improved survival

Introduction: Cholangiocarcinoma (CCA) is the second most common type of primary liver cancer. Several factors, such as epigenetic changes in promoter genes, gene expression, and microRNAs (miR), can contribute to genomic instability in cancer. This study aimed at evaluating the expression of VEGF, miRs 145-3p, and 101-3p in patients with CCA and their potential as biomarkers for diagnosis and prognosis of CCA.

The use of appropriate instruments for social assessment in health aims at both the participation of the subject and effectiveness in resolving demands. The objective of this study was to characterize the population assessed by the Validated Social Assessment Instrument and its implications; a descriptive, documental study with participant and dialectical observation. The data survey were taken from the social assessments applied from July 2020 to June 2021 in a transplant center in northwestern São Paulo state in Brazil.

Background: Hepatocellular Carcinoma (HCC) is the primary liver cancer with high incidence and mortality rates. Currently one of the major etiologies for liver disease, HCC and liver transplantation is nonalcoholic fatty liver disease (NAFLD). The aim of the present study was to evaluate the epidemiological, histopathological and clinical aspects of HCC transplant patients, with emphasis on NAFLD etiology.

The liver transplant patient was admitted to the hospital with hyperemic, granulomatous, ulcerated lesion in the anterior compartment of the right lower limb with report of local trauma. The agent was isolated from biopsy of the lesion and lymph nodes of the right lower limb. In this case, the treatment was difficult because the patient has severe pulmonary hypertension and took the following drugs: warfarin, sildenafil, and tacrolimus.

Hepatocellular carcinoma (HCC) is a cause of several deaths related to cancer worldwidely. In early stage, curative treatments such as surgical resection, liver transplant and local ablation can improve the patient ´s survival. However, the disease is detected in advanced stage; moreover some available therapies are restricted to palliative care and local treatment.

Aim: To evaluated the association of the risk factors and polymorphisms in , , and genes.

Methods: Patients with cirrhosis ( = 116), hepatocellular carcinoma (HCC) ( = 71) and controls ( = 356) were included. Polymerase chain reaction followed by enzymatic digestion and allelic discrimination technique real-time PCR techniques were used for analysis.

Hepatocellular carcinoma (HCC) is the most common primary neoplasia of the liver. Major risk factors for hepatocellular carcinoma include chronic liver diseases, carcinogenic agents, and genetic alterations as well as vascular endothelial growth factor (VEGF) involved in angiogenesis process. The aim of this study was to evaluate the association of (C936T and A1154G) with HCC and cirrhosis, in addition to serum levels of VEGF, clinical profile, lifestyle habits, and comorbidities.

Liver cancer is the sixth most commonly occurring cancer globally, and the main histological type is hepatocellular carcinoma. This type of neoplasia has a poor prognosis due to a high rate of recurrence and intrahepatic metastasis, which are closely are closely associated with the angiogenic process. Vascular endothelial growth factor (VEGF), which is under the control of hypoxia inducible factor-1α (HIF-1α), stimulates the proliferation of endothelial cells and increases cell permeability, promoting the growth, spread and metastasis of tumors.
