Drug dose and drug choice: Optimizing medical therapy for veterinary cancer.

Although novel agents hold great promise for the treatment of animal neoplasia, there may be room for significant improvement in the use of currently available agents. These improvements include altered dosing schemes, novel combinations, and patient‐specific dosing or selection of agents. Previous studies have identified surrogates for "individualized dose intensity,", for example, patient size, development of adverse effects, and pharmacokinetic parameters, as potential indicators of treatment efficacy in canine lymphoma, and strategies for patient‐specific dose escalation are discussed. Strategies for treatment selection in individual patients include conventional histopathology, protein‐based target assessment (eg, flow cytometry, immunohistochemistry, and mass spectrometry), and gene‐based target assessment (gene expression profiling and targeted or global sequencing strategies). Currently available data in animal cancer evaluating these strategies are reviewed, as well as ongoing studies and suggestions for future directions. [ABSTRACT FROM AUTHOR]
