Mammary Tumor (Fibroadenoma): Assessing a Treatment in Pet Rats

Title: Evaluation of deslorelin implants on fibroadenoma recurrence in rats

Purpose: The objective of this clinical study is to determine whether the deslorelin implant (Suprelorin®) can prevent the recurrence of certain mammary tumors in rats, as these tumors frequently re-occur after surgical removal.

Contact: Email capeservice@ucdavis.edu 

Participation Requirements: Female rats that are not spayed and diagnosed with a subcutaneous mass that could be a mammary tumor

Initial Evaluation for Participation: Physical examination indicating no contraindication for anesthesia


  • While your rat is under anesthesia, the mass will be surgically removed. It will then be analyzed to confirm diagnosis of a fibroadenoma, a process that may take several days.
  • If the diagnosis is confirmed and you have elected for your rat to have the implant:
    • The implant will be placed while your rat is sedated, approximately one month of the mass being removed.
    • A recheck exam will be performed every 6 months or sooner if you detect a mass. During these examinations, your veterinarian will be performing a complete physical examination and palpate for masses in the mammary tissue as is standard for any consultation.
  • You may also receive phone calls or email every few months to monitor how your rat is doing.

Benefits: The study will cover the cost of the implant while your rat is enrolled in the trial.

Although there are potentially no benefits if your rat receives the placebo (inactive) implant, the active implant may help to prevent the recurrence of the mammary tumor.

Owner Responsibilities: If you allow your rat to participate in this study, you will be responsible for bringing your rat to your veterinarian for a routine visit every 6 months (or more often if you notice any mass recurrence or any abnormal clinical signs) and covering costs of the anesthetic and surgical fees, post-operative treatments and hospitalization, as well as recheck examinations required for your rat. If the implant proves to prevent mammary tumor recurrence and you would like your rat to be implanted with another deslorelin implant in a year, the cost of this implant will be at your charge.
