Immunohistochemical characterization of peritoneal inclusion cysts with squamous metaplasia

Histopathology, EarlyView.
Aims Peritoneal inclusion cysts (PICs) are mesothelial‐lined cysts that can uncommonly develop squamous metaplasia. Here, we describe the immunophenotype of PICs with squamous metaplasia using a comprehensive immunohistochemical (IHC) panel. Methods and results We collected surgical excisions of PICs with squamous metaplasia from our institution and ...

Molecular Features of Metaplastic Breast Carcinoma: An Infrequent Subtype of Triple Negative Breast Carcinoma

Cancers, 2020
Metaplastic breast carcinoma (MBC) is a heterogeneous group of infrequent invasive carcinomas that display differentiation of the neoplastic epithelium towards squamous cells and/or mesenchymal-type elements. Most MBC have a triple negative phenotype and

A Phase II Pilot Study of Anti‐PD‐L1, Durvalumab, and a PARP Inhibitor, Olaparib in Patients With Metastatic Triple‐Negative Breast Cancer With or Without Germline BRCA Mutation

Cancer Medicine, Volume 14, Issue 23, December 2025.
ABSTRACT Background Immunostimulatory effects of PARP inhibitors could increase sensitivity to immune checkpoint inhibitors. The previous Phase II trial (MEDIOLA) reported clinical benefits of durvalumab and olaparib (D + O) in patients with germline BRCA‐mutated (gBRCAm) HER2‐negative metastatic breast cancer.

Epigenetic dynamics in gastric cancer precancerous lesions: From molecular mechanisms to precision risk stratification

Clinical and Translational Discovery, Volume 5, Issue 6, December 2025.
Gastric precancerous lesions undergo dynamic epigenetic alterations—including DNA methylation, 5‐hydroxymethylcytosine, non‐coding RNAs, and RNA editing—throughout the Correa's cascade. The integration of these multi‐omics epigenetic signatures facilitates non‐invasive risk stratification, which guides personalised surveillance strategy and targeted ...
