LNMRI for Detecting Metastatic Lymph Nodes

Trial ended August 2021.

Patient Disease:

Canine Oral Tumors (melanoma, fibrosarcoma, tonsillar or salivary carcinoma)

Study Name:

LNMRI for Detecting Metastatic Lymph Nodes

Purpose of the study:

  • To determine if a novel, non-invasive imaging method utilizing iron nanoparticles is more sensitive than other types of imaging for diagnosing metastatic lymph nodes

Primary Eligibility Criteria:

  • Dogs with a diagnosis of oral melanoma, oral fibrosarcoma, tonsillar squamous cell carcinoma, or salivary carcinoma; other oral tumor types may be eligible on a case-by-case basis
  • Surgical removal of primary tumor okay if surgical site can be easily identified
  • No prior chemotherapy or radiation to the head/neck region
  • No prior removal of head/neck lymph nodes
  • Pets must come to CSU for all visits related to the clinical trial

Study Protocol:

  • Day 1: Dogs anesthetized for short MRI +/- CT scan; after recovery from anesthesia, iron nanoparticle drug is given as an IV infusion
  • ​​​​​Day 3: Anesthesia for repeat MRI +/- CT scan (if not done on Day1) 48 hours following drug infusion followed by surgical removal of regional lymph nodes

Owner Responsibilities:

  • You are responsible for the initial testing to determine study eligibility (sampling of the primary tumor, chest radiographs and bloodwork; approximately $400-700 depending on the tests performed) and any other tests recommended by your pet’s oncologist
  • You are expected to make and keep all appointments associated with the study

Financial Incentives:

  • All costs related to the study protocol including the costs of imaging, drug infusion, and lymph node removal are covered by the study
  • Owners will receive a $250 credit to their VTH account upon completion of the study to put towards further treatment
  • Should your pet have any significant allergic reactions during administration of the medication and require hospitalization, the trial will pay for treatments associated with this incident only
