RESULTS OF SURGICAL TREATMENT OF ADRENAL TUMORS WITH OR WITHOUT INVOLVEMENT OF THE VENA CAVA: 42 DOGS (1993– 2003). F. Bernard , E. Monnet , EJ Ehrhart , S. J. Withrow . University College Dublin, Belfield, Ireland; Colorado State University, Fort Collins, Colorado, USA. Introduction: The purpose of this study was to evaluate the effect of involvement of the vena cava on outcome of dogs surgically treated for adrenal tumor. Material and Methods: Medical records of dogs surgically treated for an adrenal mass were reviewed for signalment, duration of signs prior to presentation, complete blood count values, serum chemistry panel values, concurrent diseases, adrenal gland affected, histopathologic diagnosis, surgical procedure, caudal vena cava involvement, and development of complications. Short-term survival was defined as within 14 days after surgery. Proportional hazard univariate analysis was used to evaluate risk factors for survival. Results: Eight dogs were diagnosed with an adrenocortical adenoma, 22 with an adrenocortical carcinoma, and 12 with a pheochromocytoma. Eight dogs had involvement of the vena cava. Involvement of the vena cava (HR: 5.5, 95% CI: 2.2–24.0, p1⁄4 0.002), nephrectomy (HR: 3.0, 95% CI: 1.3–7.0, p1⁄4 0.002), transfusion during anesthesia (HR: 5.4, 95% CI: 2.0–24.0, p1⁄4 0.0003), DIC (HR: 7.9, 95% CI: 2.4–37.0, p1⁄4 0.0006), hypotension (HR: 5.1, 95% CI: 1.8–22.8, p1⁄4 0.002), and peritonitis (HR: 3.6, 95% CI: 1.2– 10.4, p1⁄4 0.02) were risk factors for short-term survival. Extensive involvement of the vena cava extending cranially to the hepatic veins was a risk factor for short-term survival (HR: 8.2, 95% CI: 3.0–37.3, p o0.0001). Involvement of the caudal vena cava had no effect on long-term survival (HR: 2.6, 95% CI: 0.5–8.3, p1⁄4 0.19). Discussion/Conclusion: Involvement of the vena cava is associated with a higher surgical mortality rate but it does not affect the long-term prognosis in dogs with an adrenal mass. The extent of the vena cava involvement should be determined before surgical treatment of adrenal tumor.
