Incorporation of PET/CT into Radiation Therapy Planning for Canine Nasal Tumors

Study Details:  Incorporation of PET/CT into Radiation Therapy Planning for Canine Nasal Tumors.

Species: Canines

Tumor: Nasal tumors

Purpose of study: Nasal tumors are common in dogs and most effectively treated with radiation therapy. Unfortunately, recurrence rate of nasal tumors unfortunately remains high even with the most current radiotherapy and imaging techniques. The use of PET/CT for radiation treatment planning has greatly improved treatment of human head and neck cancers but this technology has not been widely used in pets with cancers, including nasal tumors. PET stands for Positron Emission Tomography, which uses a radioactively labeled glucose tracer to image and measure the most aggressive areas of a tumor based on its metabolism, whereas more traditional CT imaging allows you to only visualize the anatomy. PET/CT is completely new to veterinary medicine and we expect it to provide valuable information that can improve our diagnosis and treatment of veterinary cancer patients.  We will then compare the results from the two types of scans (PET/CT versus CT scan) to determine which most accurately defines tumor margins and ultimately results in the most effective treatment of the disease.

As part of this clinical trial, your pet will receive a PET/CT scan under general anesthesia for further diagnostic information and radiation planning for treatment of his/her nasal tumor. Your pet will recover from anesthesia in the nuclear medicine ward and stay there for several hours after the procedure while the radioactive glucose tracer fades away. Participation in the clinical trial is complete once the PET/CT has been performed. Your pet may benefit directly from having a PET/CT scan if this new type of scan allows us to identify additional areas of tumor that should be treated. For more information, click here.
