I have a question for the vets on the list. Virtually all of the discussion about the treatment of insulinoma focuses on corticosteroid treatment. Have any of the vets on the FML tried or heard of using streptozocin? (The brand name is Zanosar by Upjohn, although it may go by a different trade name if it's used for veterinary practice.) As I understand it, streptozocin preferentially kills off islet cells, which secrete insulin. Could this be used as Lysodren is used in treating adrenal tumors? Streptozocin is pretty toxic to the kidneys, so it's not a wonder drug, but I haven't heard any mention of this among many discussions of insulinoma in ferrets. --Jeff Johnston [Posted in FML issue 1548]
