FLOW CYTOMETRIC ANALYSIS OF CANINE MAST CELL TUMOR: DIAGNOSTIC AND PROGNOSTIC APPLICATIONS
Mast cell tumors (MCTs) are the most frequent skin neoplasms in dogs. They first metastasize to lymph nodes (LNs), and can later involve the spleen, liver, bone marrow, and peripheral blood. Early and accurate detection of metastasis is critical for prognosis and treatment planning. My studies evaluate flow cytometry (FC) as a diagnostic and prognostic tool.
A first study validates a FC panel for detecting mast cells in peripheral blood, bone marrow, and LN aspirates, demonstrating high precision and accuracy.
Another study compares FC with cytology and histopathology for identifying metastatic LNs, showing FC could distinguish metastatic (HN2-HN3) from non-metastatic (HN0-HN1) nodes using a 0.3% mast cell threshold, achieving 84.3% accuracy. When combined with cytology, accuracy rose to 92.2%. A FC cutoff of 1.1% is the best to detect HN3 LNs, with a specificity of 98% and sensitivity of 84.2%; an infiltration >4% allows to reach a specificity of 100% for HN3 cases.
A third study assesses the prognostic significance of mast cell percentages in sentinel LNs. Patients with nodal mast cells levels exceeding 1.1% and 4% are respectively 10 and 40 times more likely to experience tumor progression. Therefore, dividing dogs in high-risk (>4%), intermediate-risk (1.1%-4%), and low-risk (<1.1%) groups for disease progression, more tailored treatment and monitoring can be applied, thus improving outcome.
These results position FC as a minimally invasive, accurate method for diagnosing, staging, and prognosticating canine MCTs. Incorporating FC into clinical workflows could enhance early detection, guide individualized treatment, and improve outcome prediction for dogs with MCTs.
