[Determination of the potential doubling time of tumors using bromodeoxyuridine and flow cytometry]

Tumor growth-rate affects prognosis and treatment planning. The injection of bromodeoxyuridine in dogs and cats permits determination of the potential doubling time following a biopsy of neoplastic tissue and flow cytometric analysis. The essentially non-invasive method gives exact results within 24 hours. This report describes a method to measure potential tumor doubling time of different tumors, and presents results of canine and feline tumors.
