Membranous Overexpression of Fibronectin Predicts Microvascular Invasion and Poor Survival Outcomes in Patients with Hepatocellular Carcinoma.
Gut Liver
January 2025
Department of Pathology, Seoul National University College of Medicine, Seoul, Korea.
Background/aims: Fibronectin (FN) has recently been identified as being overexpressed in patients with hepatocellular carcinoma (HCC) and deemed a promising biomarker of vascular invasion. The aim of this study was to examine the patterns of FN expression in HCC cells and their clinicopathological significance, such as their association with vascular invasion and angiogenesis patterns.
Methods: Immunohistochemical analysis of FN was conducted using tissue microarrays from 258 surgically resected HCCs and matched nontumorous liver tissues.
PLASMA EXPRESSION LEVELS OF MICRORNA-21 MIGHT HELP IN THE DETECTION OF HCV PATIENTS COMPLICATED BY HEPATOCELLULAR CARCINOMA.

Department of Internal Medicine, Faculty of Medicine, Benha University, Benha, Egypt.
Objective: To investigate the ability of the estimated plasma gene-expression levels of microRNA (miR)-21 and 126 to define patients suspected to have hepatocellular carcinoma (HCC) among patients with complicated hepatitis-C virus (HCV) infection.
Methods: Patients with uncomplicated (U-HCV) or complicated HCV underwent clinical and ultrasonographic (US) evaluations and assessment for the computerized hepatorenal index, hepatic steatosis index and fibrosis indices. Blood samples were obtained for estimation of serum levels of alpha-fetoprotein (AFP) and tumor necrosis factor-α (TNF-α), and plasma expression levels of miR-21 and miR-126 using the quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR).
Extracranial and nonvaginal extragonadal malignant germ cell tumors: 12 cases at a Chinese institution over the last 38 years.
Arch Gynecol Obstet
January 2025
Department of Obstetrics and Gynecology, National Clinical Research Center for Obstetric & Gynecologic Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Purpose: To provide a comprehensive understanding and propose a strategy for the management of extragonadal malignant germ cell tumors (EMGCTs) arising from extracranial and nonvaginal sites.
Methods: We retrospectively reviewed the cases of 12 patients with EMGCTs arising from extracranial and nonvaginal sites treated in our center over the past 38 years. Data on clinicopathological characteristics, treatment modalities, and follow-up information were analyzed.
Paratesticular/inguinal SMARCB1/INI1 deficient carcinomas with yolk sac tumour-like differentiation are aggressive somatic malignancies.
Histopathology
January 2025
Department of Diagnostic and Molecular Pathology, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.
Aims: Extragonadal yolk sac tumour (YST) is rare, and may present a diagnostic challenge. YST differentiation was recently reported in some somatically derived tumours in the sinonasal location and in the female genital tract, together with a SMARCB1/INI1 loss. We report two paratesticular/inguinal tumours with striking morphological and immunohistochemical similarities with YST, further expanding the spectrum of extragonadal tumours with YST-like morphology and SMARCB1/INI1 loss.

Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality globally due to HCC late diagnosis and limited treatment options. MiRNAs (miRNAs) emerged as potential biomarkers for various diseases, including HCC. However, the value of miRNA-101 as a serum biomarker for HCV-induced HCC has not been fully investigated.
