Comparison of Auto‐Contouring Tools for Delineation of Normal Organs at Risk in Paediatric Patients Undergoing Radiotherapy

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S62-S72, April 2026.
Contouring organs at risk (OARs) manually in paediatric patients undergoing cranial‐spinal radiation therapy (CSI) is a time‐consuming, labour‐intensive task. This study aims to assess the accuracy and clinical acceptability of auto‐contours produced by the Siemens DirectORGANS auto‐contouring software on paediatric patients receiving CSI treatment ...

Oncolytic Therapy: Delivery System and New Therapeutic Strategies for Cancer

MedComm, Volume 7, Issue 4, April 2026.
This review summarizes recent advances in nanoparticle‐ and cell‐mediated OVs delivery strategies that improve biodistribution and tumor targeting while limiting immune clearance. It also examines combination approaches that enhance therapeutic efficacy through tumor microenvironment modulation or immune activation, thereby overcoming immunosuppression

A Rare Presentation of Teratocarcinosarcoma as a Carinal Mass With Review of Literature

Respirology Case Reports, Volume 14, Issue 4, April 2026.
We report a rare presentation of teratocarcinosarcoma arising at the carina with bilateral main bronchial obstruction, resulting in critical airway compromise. Urgent bronchoscopic debulking followed by definitive chemoradiotherapy achieved sustained disease control with no recurrence at 4‐year follow‐up. This case highlights the importance of accurate

First Case of Neuroblastoma‐Like Somatic‐Type Malignancy Arising in the Teratomatous Component of a Mixed Non‐Seminomatous Testicular Germ Cell Tumor in an Adult

Clinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Somatic malignant transformation (SMT) in germ cell tumors (GCTs) is a rare but clinically significant event. Among non‐seminomatous germ cell tumors (NSGCTs), teratomas can undergo malignant transformation, with neuroblastoma‐like differentiation being exceptionally rare.
