Plain-English summary

Eight dogs with spinal pain and neurological issues were found to have tumors in their vertebrae. Among them, four had a single tumor (solitary plasmacytoma), three had multiple tumors (multiple myeloma), and one had two tumors without spreading. Treatment varied: two dogs with multiple myeloma received chemotherapy and lived for 17 and 26 months, while two dogs with solitary plasmacytomas underwent both chemotherapy and radiation. One of these dogs lived for four months before being euthanized due to complications, while the other survived an impressive 65 months before developing multiple myeloma.

Abstract

The case histories of 8 dogs with spinal pain and neurologic deficits associated with vertebral plasma cell tumor are reviewed. Four dogs had solitary plasmacytoma, 3 had multiple myeloma, and 1 dog had 2 vertebral lesions with no evidence of disseminated disease. Four dogs were treated: 2 with multiple myeloma received chemotherapy only and survived 17 and 26 months, respectively. Two dogs with solitary plasmacytomas of the spine had chemotherapy and radiotherapy: the 1st survived 4 months and was euthanized after developing radiation myelopathy; the 2nd survived 65 months before developing multiple myeloma. The diagnosis of solitary plasmacytoma of the spine versus multiple myeloma is discussed.
