摘要
背景肾上腺受体拮抗剂治疗嗜铬细胞瘤（PCC）犬的存活率尚未被描述或与手术治疗病例进行比较。假设/目的本研究的目的是评估医学和外科治疗犬PCC的生存率，并探讨与生存率相关的因素。实验动物：255只患PCC的狗，分别接受不切除肾上腺的α -肾上腺受体拮抗剂（AA）治疗（第1组，n = 75）、肾上腺切除+/ - AA治疗（第2组，n = 128）或两者均不治疗（第3组，n = 52）。方法回顾性的、多中心的病历资料。使用Kaplan-Meier估计计算1组和2组的中位总生存时间（OST），然后使用Log-Rank检验比较1组和2组之间的差异。Cox比例风险分析确定了与1组和2组单独或联合生存相关的因素。结果所有病例的中位OST为854天（95% CI: 572-1136）。组1的中位OST（247天，95% CI: 76-418天）低于组2（927天，95% CI: 587-1267天；p < 0.001）。第2组术前AA治疗的88/92只（97.8%）存活至出院，未术前AA治疗的23/27只（85.2%）存活至出院（p = 0.03）。在两组合并（HR 0.5; 95% CI 0.3 - 0.9; p = 0.02）和单独组2 （HR 0.3; 95% CI 0.1-0.7; p = 0.01）中，就诊时缺乏临床体征与生存率增加相关。结论及临床意义与未行肾上腺切除术的犬相比，行肾上腺切除术的犬PCC存活时间更长。
A Multicenter, Retrospective Analysis of Long-Term Survival in 255 Dogs With Pheochromocytoma Treated With Alpha-Adrenoreceptor Antagonists or Surgery (2010–2021)
Background
The survival of dogs with pheochromocytoma (PCC) treated with adrenoreceptor antagonists has not been described or compared to surgically managed cases.
Hypothesis/Objectives
The objective of this study is to evaluate the survival of medically and surgically managed dogs with PCC and investigate factors associated with survival.
Animals
Two hundred fifty-five dogs with PCC, treated with alpha-adrenoreceptor antagonists (AA) without adrenalectomy (Group 1, n = 75), adrenalectomy +/– AA (Group 2, n = 128), or neither treatment (Group 3, n = 52).
Methods
Retrospective, multicenter review of medical records. Median overall survival time (OST) for Groups 1 and 2 combined was calculated using Kaplan–Meier estimates, and then compared between Group 1 and Group 2 using Log-Rank testing. Cox proportional hazard analysis identified factors associated with survival in Groups 1 and 2 individually and combined.
Results
Median OST for all cases was 854 (95% CI: 572–1136) days. Median OST was lower in Group 1 (247 days, 95% CI: 76–418 days) than in Group 2 (927 days, 95% CI: 587–1267 days; p < 0.001). In Group 2, 88/92 dogs (97.8%) that received presurgical AA treatment survived to discharge compared to 23/27 (85.2%) that did not receive AA pretreatment (p = 0.03). Lack of clinical signs at presentation was associated with increased survival in both groups combined (HR 0.5; 95% CI 0.3–0.9; p = 0.02) and in Group 2 alone (HR 0.3; 95% CI 0.1–0.7; p = 0.01).
Conclusions and Clinical Importance
Dogs with PCC treated with adrenalectomy have longer survival compared to those managed with AA without adrenalectomy.
