PD‐L1, PD‐1, and CTLA‐4 mRNA In Situ Expression by Canine Oral Melanoma Cells and Immune Cells of the Tumour Microenvironment

open access: yesVeterinary and Comparative Oncology, Volume 23, Issue 2, Page 141-151, June 2025.
ABSTRACT Canine oral melanoma (OM) exhibits poor prognosis and limited treatment options. The success of immune checkpoint inhibitors (ICIs) in human melanoma has driven interest in similar therapeutic approaches in the dog, although the immunosuppressive mechanisms adopted by canine OM remain unclear. This study aimed to evaluate the expression of the

Novel clinical trial designs emerging from the molecular reclassification of cancer

open access: yesCA: A Cancer Journal for Clinicians, Volume 75, Issue 3, Page 243-267, May/June 2025.
Abstract Next‐generation sequencing has revealed the disruptive reality that advanced/metastatic cancers have complex and individually distinct genomic landscapes, necessitating a rethinking of treatment strategies and clinical trial designs. Indeed, the molecular reclassification of cancer suggests that it is the molecular underpinnings of the disease,
