Hypothesis: Dogs with primary lung tumors can be safely and effectively treated with image-guided SRS.

Background and Rationale

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. The radiation is intended to damage the DNA of the cancer cells beyond repair so that they stop dividing or die. Stereotactic radiosurgery (SRS) is an advanced form of radiation therapy that delivers high-dose radiation with sub-millimeter precision, enabling precise targeting of a tumor with minimal collateral damage to nearby healthy tissue.

SRS has been used to successfully treat both operable and inoperable lung tumors in people.1–7 Studies have revealed that SRS is well-tolerated, results in minimal complications and toxicities, maintains or improves quality of life, and results in equivalent survival times when compared to surgery for people with operable tumors.1–4,6 Additionally, the peri-procedural morbidity and mortality rate is less for the SRS-treated patients than for those treated surgically.

Study Design

This is a single-arm prospective study. Eligible patients will be treated with a metric-driven protocol consistent with the quality assurance practices of PetCure Oncology and the PetCure Scientific Advisory Board. The protocol has been developed with the guidance of the Scientific Advisory Board.

Eligibility Criteria

Any canine patient diagnosed with a primary lung tumor is potentially eligible for study entry provided they meet all of the following requirements:

  1. Histologic or cytologic confirmation of malignancy is desired, but this requirement may be waived for patients with central/inaccessible tumor locations
  2. Complete reference lab bloodwork must be available and less than two weeks old
  3. A diagnostic CT scan of the thorax must be performed prior to patient enrollment. Evidence of metastatic disease is exclusionary for this study, but alternative treatment paths may be available.
  4. Significant co-morbidities that would impact the patient’s ability to tolerate/survive multiple anesthetic events is exclusionary
  5. Caregivers must sign informed consent that they understand this is an ongoing clinical study to better define the role of SRS in the treatment of primary lung tumors in dogs
  6. Caregivers must agree to follow the prescribed follow-up procedure, including repeat CT scans at 3 and 12 months post-treatment and an autopsy at PetCure’s expense for any patient that dies following enrollment in the study

Terms of the Study

PetCure Oncology is interested in better defining the role of SRS for the treatment of canine patients with primary lung tumors. While this form of therapy is already being used to treat veterinary patients with lung cancer, there are no controlled, prospective studies in the veterinary literature that are designed to truly define the risks and benefits of this kind of radiation therapy for tumors of the canine lung. In order to facilitate case accrual in an appropriate manner, PetCure Oncology will:

  1. Provide an SRS video consult free of charge
  2. Provide the treatment-planning CT free of charge
  3. Provide entire SRS treatment course at subsidized cost of $4,500 for up to 30 enrolled patients
  4. Provide the two-week checkup free of charge
  5. Provide the 3- and 12-month follow-up CT free of charge
