Abstract

Osteosarcoma (OSA) is the most common observed primary bone tumor of dogs. This retrospective study, carried out from January 2001 to June 2004, included a total of 50 dogs with appendicular OSA, 28 females and 22 males, diverse races, aged between 1 and 16 years old. Most of the dogs were Rottweiler race (16 dogs), aged between 5 and 9 years old and weighing between 28 and 43kg. Thirty-seven animals showed the tumor in thoracic members and the most affected regions were distal radius, distal radius and ulna (32%) and the proximal humerus (28%). To determine the diagnosis it was used fine needle aspiration cytology associated to histopathology (29 dogs). Metastasis were observed only in 2 animals at the moment of the medical visit. We can conclude that middle-aged dogs weighting more than 30kg are more predisposed to develop this tumor. Thoracic members are most affected. Pulmonary metastasis are rarely detected at the moment of the medical visit. Animals without treatment have evolution time and shorter survival after medical visit. The surgical intervention associate to chemotherapy provides a greater survival time.
