Abstract

Background/aim: Clinical staging has become essential in veterinary oncology. It is crucial for creating effective treatment plans and predicting outcomes. Whole-body computed tomography (WBCT) can serve as a comprehensive staging examination, offering a detailed view of a patient's internal anatomy. This retrospective study aimed to assess the diagnostic yield of WBCT in diagnosing cancer in dogs and cats.

Patients and methods: We reviewed medical records of cats and dogs that underwent a WBCT scan between January 2016 and May 2023. Only cases with a confirmed cytological or histological diagnosis of the primary tumor and complete medical records were considered. We collected data on histological diagnoses and diagnostic methods used.

Results: Our study included 57 animals that underwent WBCT for cancer-related reasons. Metastases were detected in 14 dogs, with four showing metastases in multiple locations, five in the lungs, three in the lymph nodes, one in the skeleton, and one in the liver, yielding a diagnostic rate of 31.8%. In cats, metastases were detected in six cases (five in the lungs and one in the lymph nodes), with a diagnostic yield of 46.2%. WBCT identified metastasis in over 35% of cases, including those outside the thoracic and abdominal cavities, indicating potentially greater accuracy than radiography and ultrasound.

Conclusion: WBCT is an effective and safe method for tumor staging and oncological diagnosis in dogs and cats.

肿瘤环境下猫狗全身计算机断层扫描的诊断率

背景/目的：临床分期在兽医肿瘤学中已变得至关重要。它对于制定有效的治疗计划和预测结果至关重要。全身计算机断层扫描（WBCT）可以作为一种全面的分期检查，提供患者内部解剖的详细视图。本回顾性研究旨在评估WBCT诊断狗和猫癌症的诊断率。患者和方法：我们回顾了2016年1月至2023年5月期间接受WBCT扫描的猫和狗的医疗记录。只有细胞学或组织学诊断证实原发肿瘤并有完整医疗记录的病例才被考虑。我们收集了组织学诊断和诊断方法的资料。结果：我们的研究纳入了57只因癌症相关原因接受了WBCT的动物。在14只狗中检测到转移，其中4只显示多部位转移，5只在肺部，3只在淋巴结，1只在骨骼，1只在肝脏，诊断率为31.8%。在猫中，6例发现转移（5例在肺部，1例在淋巴结），诊断率为46.2%。WBCT在超过35%的病例中发现了转移，包括胸腔和腹腔外的转移，表明可能比x线摄影和超声更准确。结论：WBCT是一种安全有效的犬猫肿瘤分期和肿瘤诊断方法。
