Molecular characterization of EBV-associated primary pulmonary lymphoepithelial carcinoma by multiomics analysis.
BMC Cancer
January 2025
Department of Respiratory and Critical Care Medicine, The First Affiliated Hospital of Guangxi Medical University, Nanning, Guangxi Zhuang Autonomous Region, China.
Background: Primary pulmonary lymphoepithelial carcinoma (pLEC) is a subtype of non-small cell lung cancer (NSCLC) characterized by Epstein-Barr virus (EBV) infection. However, the molecular pathogenesis of pLEC remains poorly understood.
Methods: In this study, we explored pLEC using whole-exome sequencing (WES) and RNA-whole-transcriptome sequencing (RNA-seq) technologies.
How Do I Diagnose Fibrolamellar Carcinoma?
Mod Pathol
January 2025
Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN. Electronic address:
Fibrolamellar carcinoma (FLC) is a unique primary carcinoma of liver that is characterized by distinct morphologic findings and a recurrent DNAJB1::PRKACA gene fusion. It typically presents in young individuals without underlying liver dysfunction. FLC is a difficult diagnosis when based only on morphology and misdiagnosis is not uncommon.

Endocrinol Metab (Seoul)
January 2025
Department of Endocrinology, JSS Medical College, JSS Academy of Higher Education and Research, Mysore, India.
Background: Data on the carcinogenic potential of tirzepatide from randomized controlled trials (RCTs) are limited. Furthermore, no meta-analysis has included all relevant RCTs to assess the cancer risk associated with tirzepatide.
Methods: RCTs involving patients receiving tirzepatide in the intervention arm and either a placebo or any active comparator in the control arm were searched through electronic databases.
Ongoing chromothripsis underpins osteosarcoma genome complexity and clonal evolution.
Cell
January 2025
European Molecular Biology Laboratory, European Bioinformatics Institute, Hinxton CB10 1SA, UK. Electronic address:
Osteosarcoma is the most common primary cancer of the bone, with a peak incidence in children and young adults. Using multi-region whole-genome sequencing, we find that chromothripsis is an ongoing mutational process, occurring subclonally in 74% of osteosarcomas. Chromothripsis generates highly unstable derivative chromosomes, the ongoing evolution of which drives the acquisition of oncogenic mutations, clonal diversification, and intra-tumor heterogeneity across diverse sarcomas and carcinomas.

Int J Surg Case Rep
January 2025
Department of Pathology, The First Affiliated Hospital of Zhejiang University School of Medicine, No.79 Qingchun Road, Hangzhou, Zhejiang 310003, China. Electronic address:
Introduction: Clear cell hidradenoma (CCH) is a rare type of benign breast tumor that may undergo malignant transformation in a few cases. It clinically manifests as a painless breast mass, and may include nipple discharge. Complete surgical excision with adequate safety margins is the primary treatment.
