PROGNOSIS FOR DOGS WITH STAGE-I OR STAGE-II SPLENIC HEMANGIOSARCOMA TREATED BY SPLENECTOMY ALONE - 32 CASES (1991-1993)

A retrospective analysis was performed on the case records of 32 dogs with Stage I or II splenic hemangiosarcoma that were treated by splene ctomy alone and that survived the seven-day postoperative period. Medi an survival time for these 32 cases was 86 days (mean, 116 days; range , 14 to 470 days), and the one-year survival rate was estimated to be 6.25%. Survival was not influenced by signalment, presenting signs, st age of disease, or clinicopathological findings. The data provides a b asis from which to evaluate adjuvant chemotherapy for splenic hemangio sarcoma that is confined to the spleen macroscopically.
