About this episode
Send a textA splenic mass is one of those findings that can flip a normal day into a crisis. You may have an older Labrador or Golden Retriever, an ultrasound that shows a splenic tumor, and an owner asking the question you cannot fully answer yet: “Is it cancer?” We sit down with Dr. Janet Grimes to unpack why that gap between suspicion and certainty is so hard in canine medicine and why better preoperative diagnostics for splenic masses could change everything from emergency decisions to long-term screening.We walk through what veterinarians currently juggle when counseling clients, including the role of hemoabdomen, the wide spread in prognosis between benign lesions and canine hemangiosarcoma, and how rules of thumb like the double two-thirds rule fit (or do not fit) in different clinical scenarios. Then we zoom in on the science of microRNAs: tiny non-coding RNA molecules that regulate gene expression and can be detected in circulation, making them promising minimally invasive biomarkers for veterinary oncology.Dr. Grimes explains how a multi-marker microRNA panel is built from blood samples and measured with quantitative RT-PCR, why panels can be more specific than single markers, and what it could look like to use this as a send-out test today with the longer-term goal of a cage-side diagnostic. We also discuss the real-world barriers: differentiating hemangiosarcoma from other splenic malignancies, avoiding misleading results in sick dogs, and integrating any new test as an adjunct to physical exam, imaging, and standard lab work.If you care about earlier cancer detection in dogs, smarter decision-making around splenectomy, and the future of blood-based cancer diagnostics, listen through to the end and share this with a colleague.
