Iridium-192 interstitial brachytherapy as adjunctive treatment for canine cutaneous mast cell tumors

J Am Anim Hosp Assoc. 2004 Jul-Aug;40(4):309-15. doi: 10.5326/0400309.

Abstract

Eleven dogs with cutaneous mast cell tumors (MCTs) were treated with surgery and iridium-192 ((192)Ir) interstitial brachytherapy. Minimum tumor doses ranged from 47.2 to 63.3 Gy. Treated tumors were classified as grade II (n=7) or III (n=4). Five dogs had recurrences with a median progression-free interval of 1391 days, and six dogs had no recurrence at a median follow-up time of 942 days. Acute adverse effects were well tolerated, and late effects were mild. One dog developed a second tumor of a different cell type in the radiation treatment field.
