Lymph Node Irradiation for Canine Patients with Oral Squamous Cell Carcinoma

Trial ended September 2020.

Patient Disease:

Canine Oral Squamous Cell Carcinoma

Study Name:

Impact of Regional Lymph Node Irradiation on the Anti-Tumor Immune Response for Canine Patients with Oral Squamous Cell Carcinoma

Purpose of the study:

  • To determine how lymph node radiation affects the immune response mounted against cancer cells within the tumor and throughout the body

Primary Eligibility Criteria:

  • Dogs with a confirmed diagnosis of an oral squamous cell carcinoma
  • Good function of liver and kidneys, acceptable blood cell counts, and free of severe underlying disease
  • No evidence of metastatic disease
  • One week washout from chemotherapy; no prior radiation to the tumor or regional lymph nodes
  • Pets must come to CSU for all visits related to the clinical trial

Study Protocol:

  • Once enrolled, dogs will undergo a CT scan for radiation planning purposes, as well as identification of the lymph node(s) primarily associated with the oral tumor
  • Blood, tumor, and lymph nodes will be sampled prior to, during, and after radiation therapy
  • Dogs will be treated with 3 fractions of stereotactic body radiotherapy (SBRT) on Monday, Wednesday, and Friday
  • One week following the last treatment of radiotherapy, dogs will return to the hospital for additional tissue sampling, including surgical excision of one or two lymph nodes

Owner Responsibilities:

  • Follow appointment schedule required by study protocol
  • Payment of the remainder of the costs for SBRT to treat the oral tumor (CT scan for SBRT treatment planning, SBRT), medications, any other tests recommended, as well as in the case of adverse events unrelated to the study

Financial Incentives:

  • A $2500 credit will be given to supplement treatment costs as incentive to participate in this study
  • Owners will not be charged for the additional diagnostic tests or sampling that are associated with this trial (blood work, indirect CT lymphography, tumor biopsy, lymph node aspirate, surgical excision of lymph node, additional anesthesia time) as these will be covered through the funding of the study
  • In the case of adverse events directly related to this trial, up to $2,000 will be provided to supplement the costs of supportive care
