Exosomes in Cancer: The Biology, Function, Diagnosis, and Therapy

MedComm, Volume 7, Issue 11, November 2026.
Tumor‐derived exosomes and nonmembranous extracellular nanoparticles (exomeres/supermeres) constitute a heterogeneous communication network that drives cancer progression. By shuttling functional biomolecules across tissue‐specific barriers, these nanoparticles orchestrate local microenvironmental remodeling, immune suppression, premetastatic niche ...

Reassessing Bone Marrow Aspirate and Trephine Biopsies in Staging for Paediatric and Young Adult Patients With Ewing Sarcoma and Rhabdomyosarcoma

Pediatric Blood &Cancer, Volume 73, Issue 10, October 2026.
ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.

Primitive Neuroectodermal Tumor of the Pancreas

Internal Medicine, 2009
The primitive neuroectodermal tumor (PNET) of the pancreas, a member of Ewing's sarcoma family of tumors, is extremely rare. We treated a 37-year-old Japanese man who had a solitary pancreatic tumor 40 mm in diameter and multiple hepatic tumors with surgical resection. The PNET was positive for CD99 on immunohistochemical staining. Fluorescence in situ

A Rare Instance of Adult Medulloblastoma Presenting Imaging Heterogeneity Correlating With Molecular Subtypes and Anatomical Locations

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT We report an adult medulloblastoma presenting as two imaging‐distinct lesions: a uniformly enhancing torcular mass (WNT‐activated) and a non‐enhancing cerebellar tumor (SHH‐activated). A cohort analysis confirmed torcular location favors uniform enhancement, mimicking meningioma.
