Abstract
The functional results of partial or total hemipelvectomy in seven dogs and two cats with sarcomas involving the pelvis were excellent, and the cosmetic outcome was acceptable to all owners. Tumors in two dogs were inoperable. Locally recurrent cancer occurred in two animals and metastases occurred in three animals. Three dogs survived longer than 2.5 years and the overall and disease-free survival at 12 months was 62%. It appears that osteosarcoma of the pelvis is at least as aggressive as osteosarcoma of limbs and, unless effective adjuvant therapy is used, poorer survival results are likely in dogs with osteosarcoma than with other sarcomas of the pelvis. Hemipelvectomy is an aggressive surgical procedure that can be used successfully in selected dogs and cats with cancer involving the pelvis.
