Although radiation and surgery have been combined for the treatment of cancer in humans and animals since the 1920s, little has been written about the methods of combining radiation and surgery and the efficacy of this combination for the treatment of animal tumors. The number of surgeries (1 or > 1) were compared with respect to time to first recurrence and survival time. Median survival times of dogs receiving: 1) no therapy or only symptomatic therapy, 2) surgery (+/- 125I), or 3) cobalt-60 radiation (+/- hyperthermia, +/- surgery) were 0.2, 0.9, and 4.9 months, respectively.
