    Survival data from glioma-bearing French bulldogs treated with immunotherapy, stereotactic radiation therapy, sonodynamic therapy, and palliative care

    This retrospective, multi-institutional study was conducted to examine survival outcomes in immunotherapy-treated French bulldogs compared to closely related breeds, and to French bulldogs treated with several other treatment modalities. French bulldogs treated with immunotherapy experienced significantly shorter overall survival (OS) than boxers and Boston terriers (132 vs. 221 days, respectively). French bulldogs treated with immunotherapy had no significant difference in OS compared to French bulldogs treated palliatively, whereas dogs treated with either a novel therapy involving sonodynamic therapy or stereotactic radiation therapy had significantly longer OS. This study provides evidence for an immunotherapy-resistant form of HGG in French bulldogs, suggesting that the breed harbors key molecular differences affecting the tumor and tumor-immune microenvironment and subsequent poor response to treatment.

    Transcriptomic data from RNA Sequencing of canine high grade glioma tumor samples
    (2024-11-15) Arnold, Susan A; Pluhar, G. Elizabeth; Abrahante Llorens, Juan E; saarnold@umn.edu; Arnold, Susan; University of Minnesota Canine Brain Tumor Program
    These files contain the raw data for bulk RNA sequencing performed on canine high grade glioma tumor samples. These samples were obtained from three breeds of dogs: French bulldogs, boxers, and Boston terriers. All dogs were enrolled in immunotherapy clinical trials within the University of Minnesota Canine Brain Tumor Program. They were obtained from two different time points relative to treatment: pre-treatment and post-treatment. Treatment consisted of surgical resection and immunotherapy. The purpose of these data are to provide a comprehensive profile of how canine high grade glioma transcriptomes change in response to immunotherapy treatment, and to determine if there are breed-associated changes in differential gene expression.
