DCA - Helping To Select Therapy
PetScreen provide a test that can help your vet find the best therapy for your pet. Although surgery is widely used to treat cancers, modern drug treatment has much to offer cancer patients. There are now many drugs available which are very effective and have minimal side effects. PetScreen provides a unique service to your vet to help them select the best anticancer drugs for your dog. We call this service the Directed Chemosensitivity Assay (DCA), because it helps direct your vet towards the most effective treatment for your individual pet.
As part of routine diagnosis for cancer, the vet will take a small sample of the lump (called a biopsy) for analysis under the microscope by a specialist. This analysis will tell the vet what the cancer is and will indicate how aggressive it might be. This information will then be used to decide on a course of treatment. One of the problems with chemotherapy is that the tumour might be resistant to the drug that has been chosen, and historically, the vet has no way of knowing this until treatment has started. Our DCA gives the vet more information by testing the biopsy against a range of different drugs in the laboratory before they begin treatment.
