PFS24 as a prognostic milestone in patients with newly diagnosed primary CNS lymphoma.

High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation has significantly improved overall survival (OS) in primary central nervous system lymphoma (PCNSL). However, early identification of long-term survivors remains a challenge. Progression-free survival at 24 months (PFS24) has emerged as a key prognostic marker in diffuse large B-cell lymphoma, but its relevance in PCNSL is still unclear.

ARID1A mutations protect follicular lymphoma from FAS-dependent immune surveillance by reducing RUNX3/ETS1-driven FAS-expression.

The cell death receptor FAS and its ligand (FASLG) play crucial roles in the selection of B cells during the germinal center (GC) reaction. Failure to eliminate potentially harmful B cells via FAS can lead to lymphoproliferation and the development of B cell malignancies. The classic form of follicular lymphoma (FL) is a prototypic GC-derived B cell malignancy, characterized by the t(14;18)(q32;q21)IGH::BCL2 translocation and overexpression of antiapoptotic BCL2.

Stealthy Invader: Clinically Inapparent But Rapidly Progressive Multifocal Metastatic Melanoma Unveiled as Root Cause of Liver Failure.

Background: Acute liver failure (ALF) secondary to metastatic melanoma presents a rare and diagnostically challenging clinical scenario.

Case Report: We report the case of a 57-year-old male who succumbed to fulminant liver failure attributed to hepatic infiltration by malignant melanoma. Despite extensive diagnostic evaluation, the underlying cause of ALF remained elusive until postmortem examination revealed multifocal metastatic melanoma.

PARP14 is a novel target in STAT6 mutant follicular lymphoma.

The variable clinical course of follicular lymphoma (FL) is determined by the molecular heterogeneity of tumor cells and complex interactions within the tumor microenvironment (TME). IL-4 producing follicular helper T cells (T) are critical components of the FL TME. Binding of IL-4 to IL-4R on FL cells activates JAK/STAT signaling.

Improved Recovery from Liver Fibrosis by Crenolanib.

Chronic liver diseases are associated with excessive deposition of extracellular matrix proteins. This so-called fibrosis can progress to cirrhosis and impair vital functions of the liver. We examined whether the receptor tyrosine kinase (RTK) class III inhibitor Crenolanib affects the behavior of hepatic stellate cells (HSC) involved in fibrogenesis.
