Tumor Microenvironment Biomarkers Correlated with Proliferative Activity and Immune Response in Extragastrointestinal Stromal Tumors: Exploring Variations in Different Age Groups.

Introduction: Extra-gastrointestinal stromal tumors (EGISTs) are non-gastrointestinal sarcomas originating from Cajal-like cells. Recent studies show the tumor microenvironment is crucial and highlight the importance of intra-tumoral leukocyte populations in malignancies, which are greatly impacting treatment strategies in EGISTs.

Aim And Objectives: This study aims to characterize intra-tumoral leukocyte populations in EGISTs, correlating proliferative index (ki67) with leukocyte density and examining age-related effects on proliferative activity and immune response.

Type II pleuropulmonary blastoma in a fetus: case report of a rare mesenchymal mediastinal tumor and literature review.

Mediastinal tumors are exceedingly rare during fetal development, presenting significant diagnostic challenges and potentially leading to severe outcomes such as stillbirth or metastatic disease if not promptly identified and managed. Pleuropulmonary blastomas are primitive mesenchymal tumors often linked to mutations in the DICER1 gene, indicating a hereditary pattern associated with other common adult neoplasms with dominant inheritance. This report describes a case involving a 20-year-old Caucasian woman whose pregnancy was complicated by a stillbirth in the second trimester.

GATA4 rs61277615, rs73203482, and rs35813172 in Newborns with Transposition of the Great Arteries.

Congenital heart disease is the most common malformative pathology in newborns, with a worldwide incidence at 0.4-5%. We investigated the possible relationship between variations in nucleotide sequences and specific cardiac malformations in the GATA-binding factor 4 (GATA4) exon 1 region by using Sanger sequencing.

Impact of V600E Mutation on Event-Free Survival in Patients with Papillary Thyroid Carcinoma: A Retrospective Study in a Romanian Population.

We aimed to evaluate the prognostic value of V600E mutation in a series of 127 papillary thyroid carcinoma (PTC) cases as a single factor, and in synergic interaction with other standard risk factors. V600E mutation was assessed by real-time PCR. Event-free survival (EFS) was calculated between the date of the first evaluation and the date of occurrence of an adverse event or the date of the last known status.
