Nineteen cases were treated surgically, and 1 case was treated conservatively (analgesia and monitoring). Metastatic lesions were detected in 2 of 20 dogs (10%). Four of 19 dogs (21%) treated surgically developed postoperative complications, 1 major (1 of 19 [5.2%]) and 3 minor (3 of 19 [15.8%]). Tumor recurrence was identified in 6 of 19 dogs (31.5%). The 1-, 2-, and 3-year survival rates were 95%, 72%, and 66%, respectively. None of the variables tested were associated with occurrence of complications. Increased distance from the anus, incomplete surgical margins, and decreasing surgeon experience were associated with an increased risk of recurrence. No progression to multiple myeloma was seen in any of the cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Surgical treatment of rectal plasmacytomas is associated with a low major complication rate and long survival.
