Abstract: | Medical records for 20 dogs with histologically confirmed nonsplenic hemangiosarcomas treated with palliative radiation therapy were reviewed to evaluate factors influencing tumor response and survival time. The Kaplan-Meier median survival time of dogs that received palliative radiation therapy was 95 days (range 6 to 500 days). Subjective reduction in tumor size was seen in 14 dogs, with four complete responses. Tumor location was a significant univariate prognostic factor for survival, and dogs with retroperitoneal masses had longer survival times. |
