|A retrospective study was performed on 31 dogs with completely excised, grade II, cutaneous mast cell tumors in order to determine recurrence rates and sites.
Distant tumor recurrence developed in 22% of dogs, and local tumor recurrence developed in 11% of dogs; however, the vast majority of these animals were incompletely staged initially.
Complete surgical excision of grade II mast cell tumors was associated with effective local control in 89% of these dogs.
Therefore, adjuvant radiation therapy might not be indicated in the majority of dogs with complete surgical excision.
