Article Synopsis
  • Desmoid-type fibromatosis (DTF) is a benign but aggressive tumor caused by persistent activation of fibroblasts, differing from transient activation seen in reactive fibrosis (RF).
  • A comparative analysis of gene expression in DTF and RF tissues revealed over 4,200 genes uniquely expressed in DTF, linked to development and muscle function, while RF genes pertained to immune responses.
  • Key transcription factors associated with DTF were identified, and specific genes showed potential as biomarkers, with TWIST2 outperforming β-catenin as a diagnostic indicator for DTF.

Article Synopsis
  • The study focuses on the rare types of cervical cancers known as human papillomavirus-independent squamous cell carcinoma (HPVI SCC) and adenosquamous carcinoma (HPVI ASC), analyzing their characteristics and patient outcomes.
  • Researchers reviewed medical records and pathology slides from six patients and conducted immunostaining on tumor samples, with findings showing that most patients had advanced disease at diagnosis and experienced poor outcomes, including metastasis in some cases.
  • The study concluded that HPVI SCC is aggressive with a generally poor prognosis, highlighting the need for more research to understand the link between tumor features and clinical behavior in HPVI ASC.

Background: Transcranial direct current stimulation (tDCS) is a therapeutic tool for improving post-stroke gait disturbances, with ongoing research focusing on specific protocols for its application. We evaluated the feasibility of a rehabilitation protocol that combines tDCS with conventional gait training.

Methods: This was a randomized, double-blind, single-center pilot clinical trial.

Diffuse axonal injury (DAI) following sudden acceleration and deceleration can lead to cognitive function decline. Various treatments have been proposed. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive stimulation technique, is a potential treatment for enhancing neuroplasticity in cases of brain injury.

Background: The exosome-mediated extracellular secretion of miRNAs occurs in many cancers, and RAB27A is a potent regulator of exosome secretion. For metastatic renal cell carcinoma (RCC), this study examines the mechanisms of cancer metastasis via the RAB27A-regulated secretion of specific miRNAs.

Methods: RAB27A knockdown (KD) and overexpressing (OE) RCC cells were used to examine cell migration and adhesion.

Perilipin (PLIN) is a major structural protein located on the surface of lipid droplets. PLIN plays an important role in human metabolism and is associated with metabolic diseases, such as obesity, diabetes, hypertension, and endocrine disorders. The dysregulation of lipid metabolism is one of the most prominent metabolic changes observed in cancers.

Intravascular lymphoma is characterized by an exclusively intravascular distribution of tumor cells. Intravascular natural killer/T-cell lymphoma (IVNKTL) is extremely rare, highly aggressive, commonly Epstein-Barr virus (EBV)-positive, and predominantly affects the skin and central nervous system. Here we report a case of IVNKTL diagnosed in a 67-year-old female, presenting with persistent intermittent fever and skin rashes throughout the body.

Background/aim: The neonatal Fc receptor (FcRn) is a major histocompatibility class I-like molecule responsible for the transfer of passive humoral immunity from a mother to her newborn. Recent research revealed that FcRn is involved in antigen-presentation, humoral immunity and antitumor immunity of various types of cancer, such as lung, colon and breast. Lung cancer is the leading cause of cancer-related death and non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancer.

Background/aim: RAB27A and RAB27B are involved in exosome secretion. To date, there have been many attempts to elucidate the roles of RAB27A and RAB27B in the prognosis of various cancer types. The association of RAB27A and RAB27B expression with the clinical and pathological features was evaluated in patients with stomach cancer.

Background: Myoferlin is a multifunctional protein expressed in various normal and cancer cells, with novel oncogenic roles being newly discovered. Recently, correlations have been found between myoferlin expression and unfavorable prognosis in various carcinomas. This study investigated the prognostic role of myoferlin expression in papillary thyroid carcinoma (PTC), specifically that associated with nodal metastasis.

A cardiac calcified amorphous tumor (CAT) is a rare non-neoplastic mass of the heart with histological characteristics comprising calcification and amorphous fibrous material. Little is known regarding the incidence, symptoms, and therapeutic strategies for CAT. Echocardiography and computed tomography were performed on a 48-year-old man who had a cardiac mass that was accidentally discovered on admission to a local hospital for a fracture related to a trauma that occurred 1 month prior.

Background/aim: Core needle biopsy (CNB) has been widely used as an alternative method to ultrasound-guided fine-needle aspiration cytology for histological diagnosis of thyroid specimens. However, nuclear artifactual vacuoles (NuVas) produced during tissue processing can be very difficult and sometimes impossible to distinguish from intranuclear inclusions (NuIns). P62 is an autophagy receptor that recognizes, targets, and eliminates toxic cellular materials during autophagy.

Background/aim: Programmed death ligand-1 (PD-L1) and programmed death protein 1 (PD-1) expression levels in many tumors and their correlation with prognosis have been actively studied. However, studies on PD-1 expression and its prognostic value in clear cell renal cell carcinoma (ccRCC) are limited and controversial. In this study, we describe the expression of PD-1 and its prognostic significance and association with clinical features in patients with ccRCC.

Background/aim: We aimed to evaluate the characteristics of gastric carcinoma with high excision repair cross complementing 1 (ERCC1) expression and the prognostic value of ERCC1 expression.

Materials And Methods: ERCC1 expression was evaluated by immunohistochemistry in 309 surgically resected gastric carcinoma specimens using a tissue microarray. Cancer-related survival was analysed using competing risk analysis.
